技术领域technical field
本发明涉及气相色谱试验采气注气领域，具体而言，涉及一种绝缘油容器的注气装置及其注气方法。The invention relates to the field of gas extraction and gas injection for gas chromatography experiments, in particular to a gas injection device for an insulating oil container and a gas injection method thereof.
背景技术Background technique
在利用振荡脱气法进行脱气操作的过程中，试验人员需取5ml玻璃注射器，并用氮气对该注射器进行冲洗1至2次，再用该注射器准确地抽取5.0ml氮气(即平衡气)，然后将注射器内的气体缓慢注入有试验油的另一注射器中。由于试验人员需频繁地进行取气操作，因而试验人员对取气装置的采样隔垫的扎刺十分频繁，试验人员需要经常性地进行维护检查，需经常更换采样隔垫，以防止隔垫被扎漏后平衡气体的纯度下降而影响试验的准确性。这样的取气方法费时费力，试验人员的试验工作量大时，更需频繁地更换隔垫，因而降低了试验人员的工作效率。During the degassing operation using the vibration degassing method, the tester needs to take a 5ml glass syringe, flush the syringe with nitrogen for 1 to 2 times, and then use the syringe to accurately extract 5.0ml of nitrogen (that is, the balance gas). Then slowly inject the air in the syringe into another syringe containing the test oil. Because the testers need to frequently perform air extraction operations, the testers puncture the sampling septum of the air intake device very frequently, and the testers need to perform maintenance and inspection frequently, and the sampling septum needs to be replaced frequently to prevent the septum from being damaged. After leaking, the purity of the balance gas decreases, which affects the accuracy of the test. Such a gas extraction method is time-consuming and labor-intensive, and when the test workload of the test personnel is heavy, the septum needs to be replaced more frequently, thereby reducing the work efficiency of the test personnel.

该注气装置包括第一注射筒和第二注射筒，并且第一注射筒和第二注射筒有活塞组件进行驱动，从而通过第一管路进行采气操作而从起源处抽取平衡气，并通过第二管路进行注气操作而将平衡气注入绝缘油容器中。应用本发明的技术方案，试验人员可以在试验的过程中实现抽取平衡气和注入平衡气的自动化操作，从而利用本发明的自动化的注气装置实现定量、快速地采气、注气操作，保证了试验结果的准确性，并且提高了试验工作的工作效率。The gas injection device includes a first injection cylinder and a second injection cylinder, and the first injection cylinder and the second injection cylinder are driven by a piston assembly, so that the gas recovery operation is performed through the first pipeline to extract the balance gas from the source, and The balance gas is injected into the insulating oil container through the gas injection operation of the second pipeline.

在本实施例中，第一注射筒10的容积与第二注射筒20的容积相等。 In this embodiment, the volume of the first syringe 10 is equal to the volume of the second syringe 20 . the
具体地，注气装置还包括：第一三通阀12，第一注射筒10与第一三通阀12的第一接口连通，气源200通过第一管路11与第一三通阀12的第二接口连通，绝缘油容器通过第二管路 50与第一三通阀12的第三接口连通。注气装置还包括：第二三通阀22，第二注射筒20与第二三通阀22的第一接口连通，气源200通过第三管路与第二三通阀22的第二接口连接，放空管路60与第二三通阀22的第三接口连通。优选地，第一三通阀12和第二三通阀22均为电磁阀。Specifically, the gas injection device further includes: a first three-way valve 12 , the first syringe 10 communicates with the first port of the first three-way valve 12 , the gas source 200 communicates with the first three-way valve 12 through the first pipeline 11 The second port of the insulating oil container is communicated with the third port of the first three-way valve 12 through the second pipeline 50. The gas injection device also includes: a second three-way valve 22, the second syringe 20 communicates with the first port of the second three-way valve 22, and the gas source 200 communicates with the second port of the second three-way valve 22 through the third pipeline connected, the venting pipeline 60 communicates with the third port of the second three-way valve 22 . Preferably, both the first three-way valve 12 and the second three-way valve 22 are solenoid valves.
如图1所示为该注气装置处于初始状态。此时，如图2示出了控制第第一三通阀12和第二三通阀22电路连接状态。电源100给整个控制电路提供电能。在初始状态下，必须保证电源控制开关101是处于断开状态的，控制转换开关102位于E位置处，其余控制开关则不作要求，即控制第一管路11上的第一三通阀12的开关可以处于A位置，也可以处于B位置，相同地，控制第二管路50上的第二三通阀22的开关可以处于C位置，也可以处于D位置。As shown in Figure 1, the gas injection device is in its initial state. At this time, as shown in FIG. 2 , the control circuit connection state of the first three-way valve 12 and the second three-way valve 22 is shown. The power supply 100 provides electric energy for the entire control circuit. In the initial state, it must be ensured that the power supply control switch 101 is in the disconnected state, the control switch 102 is located at the E position, and the remaining control switches are not required, that is, the first three-way valve 12 on the first pipeline 11 is controlled. The switch can be at position A or position B. Similarly, the switch controlling the second three-way valve 22 on the second pipeline 50 can be at position C or position D.
具体地，气源200的出口连接有载气管路40，载气管路40的远离气源200的一端与第一管路11和第三管路21均连接。载气管路40上设置有用于导通或切断载气管路40的载气切断阀41。Specifically, the outlet of the gas source 200 is connected with a carrier gas pipeline 40 , and the end of the carrier gas pipeline 40 away from the gas source 200 is connected with both the first pipeline 11 and the third pipeline 21 . The carrier gas pipeline 40 is provided with a carrier gas cut-off valve 41 for conducting or cutting off the carrier gas pipeline 40 .
如图3所示，当注汽装置进行采气操作的时候，工作人员将第一三通阀12的第一接口和第二接口连通，即工作人员控制如图4所示的电路连接，使得电源控制开关101闭合，然后使控制第一三通阀12的开关可以处于A位置，从而将气源与第一注射筒10连通，并且将第二三通阀22的第一接口和第二接口连通，即工作人员使控制第二三通阀22的开关处于D位置，从而将第二注射筒20与放空管路60连通。然后，工作人员开启载气管路40上的载气切断阀41,以进行取气操作。活塞组件30在初始状态下第一活塞体位于第一注射筒10的注射最处，而第二活塞体位于第二注射筒的筒口处。当载气切断阀41开启后，第一活塞体在气源200的气体压力下从左往右移动。当取气完成后，此时，第一活塞体位于第一注射筒10的筒口处，而第二活塞体则运动至第二注射筒20的注射口处。取气完成后，使控制第一三通阀的开关处于B位置如图5所示，电源控制开关101保持关闭，控制第二三通阀的开关处于D位置，并且工作人员关闭载气切断阀41，这样，气源200内的平衡气氮气就停止注入第一注射筒10内。As shown in Figure 3, when the steam injection device is performing gas extraction operations, the staff connects the first interface and the second interface of the first three-way valve 12, that is, the staff controls the circuit connection as shown in Figure 4, so that The power control switch 101 is closed, and then the switch controlling the first three-way valve 12 can be in position A, thereby connecting the air source with the first syringe 10, and connecting the first port and the second port of the second three-way valve 22 Communication, that is, the worker puts the switch controlling the second three-way valve 22 at the D position, so as to communicate the second syringe 20 with the venting pipeline 60 . Then, the staff opens the carrier gas cut-off valve 41 on the carrier gas pipeline 40 to perform the gas extraction operation. In the initial state of the piston assembly 30 , the first piston body is located at the injection end of the first syringe 10 , and the second piston body is located at the mouth of the second syringe. When the carrier gas cut-off valve 41 is opened, the first piston body moves from left to right under the gas pressure of the gas source 200 . After the gas extraction is completed, the first piston body is located at the mouth of the first syringe 10 , and the second piston moves to the injection port of the second syringe 20 . After the gas extraction is completed, put the switch controlling the first three-way valve at position B, as shown in Figure 5, keep the power control switch 101 off, keep the switch controlling the second three-way valve at position D, and close the carrier gas shut-off valve 41. In this way, the balance gas nitrogen in the gas source 200 stops injecting into the first syringe 10.
如图6和图7所示，图7示出了对应于注气操作的第一种电路连接结构示意图，工作人员对平衡气进行注气操作。工作人员使电源控制开关101保持闭合状态，控制第一三通阀的开关保持在B位置，控制第二三通阀的开关保持在D位置，这时，电路中的控制转换开关102转换到F位置处。这样，第一注射筒10与绝缘油容器连通，第二注射同与气源200连通。当开启载气切断阀41后，第二活塞体在平衡气压力的推动下将第一注射筒10内的平衡气注入绝缘油容器中，以置换出绝缘油中溶解的甲烷、乙烯、乙烷、乙炔、一氧化碳、二氧化碳和氢气等其中气体，从而对这些气体应用振荡脱气法进行色谱分析，进而分析设备的潜伏性故障。As shown in Fig. 6 and Fig. 7, Fig. 7 shows a schematic diagram of the first circuit connection structure corresponding to the gas injection operation, and the staff performs the gas injection operation on the balance gas. The staff keeps the power control switch 101 closed, the switch controlling the first three-way valve is kept at position B, and the switch controlling the second three-way valve is kept at position D. At this time, the control switch 102 in the circuit is switched to F location. In this way, the first injection cylinder 10 communicates with the insulating oil container, and the second injection cylinder communicates with the gas source 200 . When the carrier gas cut-off valve 41 is opened, the second piston body injects the balance gas in the first syringe 10 into the insulating oil container under the pressure of the balance gas to replace the methane, ethylene, and ethane dissolved in the insulating oil , Acetylene, carbon monoxide, carbon dioxide and hydrogen and other gases, so that these gases can be analyzed by vibration degassing method for chromatographic analysis, and then the latent failure of the equipment can be analyzed.
同样地，如图8所示，图8示出了对应于注气操作的第二中电路控制示意图，在进行注气时，工作人员还可以使控制第一三通阀12的开关处于A位置，而其余开关均与第一电路连接方式相同。这样的电路控制，同样能使第一注射筒10和绝缘油容器连通，气源200和第二注射筒20连通，从而工作人员开启载气切断阀41进行注气操作。Similarly, as shown in Fig. 8, Fig. 8 shows a schematic diagram of the second circuit control corresponding to the gas injection operation. During the gas injection, the staff can also make the switch controlling the first three-way valve 12 be in position A , and the other switches are connected in the same way as the first circuit. Such circuit control can also make the first injection cylinder 10 communicate with the insulating oil container, and the gas source 200 communicate with the second injection cylinder 20, so that the staff opens the carrier gas cut-off valve 41 to perform the gas injection operation.
如图9所示，在注气操作完成后，保持控制转换开关102位于F位置，而控制第一三通阀12的开关可以处于A位置，控制第二三通阀22的开关处于D位置。这样，工作人员将载气切断阀41关闭，从而停止注气操作。As shown in FIG. 9 , after the gas injection operation is completed, keep the control switch 102 at the F position, and the switch controlling the first three-way valve 12 may be at the A position, and the switch controlling the second three-way valve 22 may be at the D position. In this way, the worker closes the carrier gas cut-off valve 41, thereby stopping the gas injection operation.
如图10所示，保持电源控制开关101闭合，而将控制转换开关102位于E位置，控制第一三通阀12的开关处于A位置，控制第二三通阀22的开关处于C位置，这样，只要工作人员将控制第二三通阀22的开关再次处于D位置，就变为进行取气操作的电路控制结构了。As shown in Figure 10, keep the power supply control switch 101 closed, and the control changeover switch 102 is in the E position, the switch for controlling the first three-way valve 12 is in the A position, and the switch for controlling the second three-way valve 22 is in the C position, thus , as long as the staff will control the switch of the second three-way valve 22 in the D position again, it will become a circuit control structure for air intake operation.
在本实施例中，载气管路40的远离气源200的一端连接有三通接头，且第一管路11和第三管路21均与三通接头连通。In this embodiment, the end of the carrier gas pipeline 40 away from the gas source 200 is connected to a three-way joint, and both the first pipeline 11 and the third pipeline 21 are connected to the three-way joint.
根据本法明的另一方面，本发明提供了一种绝缘油容器的注气方法，使用了上述的注气装置，注气方法包括以下步骤：According to another aspect of the present invention, the present invention provides a gas injection method for an insulating oil container, using the above gas injection device, and the gas injection method includes the following steps:
步骤S1：将第一注射筒10与气源200连通，将第二注射筒20与放空管路60连通；Step S1: Connect the first syringe 10 to the air source 200, and connect the second syringe 20 to the venting pipeline 60;
