所述备自投装置校验仪主机（1）可与超高压行业现有的检验仪相同，也可以主要有三大部分组成：1、备自投装置跳合闸重动部分；2、模拟断路器和电压、电流切换部分3、控制、显示部分。The main unit (1) of the calibrator of the standby automatic switching device can be the same as the existing testing instrument in the ultra-high voltage industry, and can also mainly consist of three major parts: 1. The tripping and closing part of the standby automatic switching device; 2. Simulated open circuit Device and voltage, current switching
一、备自投装置跳合闸重动部分：1. The tripping and closing part of the standby automatic switching device:
由于备自投装置输出的接点容量不够，不能切断模拟断路器的回路电流，因此需要对备自投装置输出的接点进行重动以增加接点容量。结构图12和图13，简要介绍备自投装置跳合闸重动回路原理图：因为我们的备自投装置所连接的断路器有4台（工作电源的高压侧和低压侧开关，备用电源的高压侧和低压侧开关。），所以图12包括了4台开关的跳、合闸接点的重动回路。图12中KOM1和KOM2分别为备自投装置输出的跳开工作电源高压侧和低压侧开关跳闸接点，分别启动跳闸重动继电器KCO1和KCO2，然后跳开图13中的模拟断路器KM1和KM2。Since the output contact capacity of the standby automatic switching device is not enough to cut off the loop current of the simulated circuit breaker, it is necessary to reset the output contact of the standby automatic switching device to increase the contact capacity. Structural diagrams 12 and 13 briefly introduce the schematic diagram of the tripping, closing and resetting circuit of the standby automatic switching device: because there are 4 circuit breakers connected to our standby automatic switching device (high-voltage side and low-voltage side switches of the working power supply, backup power supply The high-voltage side and low-voltage side switches.), so Figure 12 includes the reset circuit of the tripping and closing contacts of the 4 switches. In Figure 12, KOM1 and KOM2 are respectively the trip contacts of the high-voltage side and low-voltage side switches of the working power supply output by the standby self-injection device, respectively start the trip reset relays KCO1 and KCO2, and then trip the analog circuit breakers KM1 and KM2 in Figure 13 .
二、模拟断路器和电压、电流切换部分：2. Analog circuit breaker and voltage and current switching part:
由于备自投装置动作需要一定的条件：1、充电条件：工作电源的三相电压为57.7V,一相电流有电流存在，并且高压侧和低压侧开关在合闸位置；2、动作条件：工作电源的高低压侧断路器因故障原因跳闸或开关偷跳，工作电源的电压、电流消失，并且备用电源电压正常。只有满足以上两个条件，备自投装置才能正确动作。为了满足备自投动作的两个条件，我们设计了模拟断路器和电压、电流、切换部分,原理如图13。原理介绍：①QF1为快分开关控制模拟断路器KM1和KM2合闸，当快分开关QF1合上时，模拟断路器KM1和KM2动作输出常开接点给备自投装置，模拟工作电源的高压侧和低压侧开关在合闸位置，同时利用KM1和KM2的辅助接点把工作电压和电流切换至备自投的电压、电流回路，模拟工作电源的正常运行状态，在这种状态下，备自投装置会延时充电。②充电完成后断开快分开关QF1，模拟断路器KM1和KM2因失电而跳开，因此备自投装置会失去工作电源的电压、电流和断路器的合闸位置接点，这样模拟断路器因故障原因跳闸或开关偷跳的状态。③由于的备自投的动作条件要求备用电源电压正常，因此设置备用电压切换继电器KM5，当合上快分开关QF2时，把电压切换至备自投装置，这样模拟备自投备用电压回路。④备自投装置在满足动作条件后正确动作，输出KC1和KC2合闸接点，合上备用电源模拟断路器KM3和KM4。通过以上介绍，模拟断路器和电压、电流、切换部分和备自投装置跳合闸重动部分相互配合能可靠校验“备自投装置”的动作逻辑，而无需停用一次设备。Certain conditions are required for the operation of the standby automatic switching device: 1. Charging conditions: the three-phase voltage of the working power supply is 57.7V, there is current in one phase current, and the high-voltage side and low-voltage side switches are in the closing position; 2. Operating conditions: The circuit breaker on the high and low voltage side of the working power supply trips or the switch slips due to a fault, the voltage and current of the working power supply disappear, and the voltage of the backup power supply is normal. Only when the above two conditions are met, the standby automatic switching device can operate correctly. In order to meet the two conditions of the standby automatic switching action, we designed the analog circuit breaker and the voltage, current, and switching parts. The principle is shown in Figure 13. Principle introduction: ① QF1 is a fast-opening switch that controls the closing of analog circuit breakers KM1 and KM2. When the quick-opening switch QF1 is closed, the analog circuit breakers KM1 and KM2 act to output normally open contacts to the backup self-switching device, simulating the high-voltage side of the working power supply And the low-voltage side switch is in the closing position, and at the same time, use the auxiliary contacts of KM1 and KM2 to switch the working voltage and current to the voltage and current loop of the standby self-injection, simulating the normal operating state of the working power supply. In this state, the standby self-injection The device will charge with a delay. ②Turn off the quick opening switch QF1 after the charging is completed, and the simulated circuit breaker KM1 and KM2 will trip due to power failure, so the standby self-switching device will lose the voltage and current of the working power supply and the closing position contact of the circuit breaker, thus simulating the circuit breaker The status of a trip or switch slipping due to a fault. ③Because the operation condition of standby automatic switching requires that the voltage of the standby power supply is normal, the standby voltage switching relay KM5 is set. When the quick release switch QF2 is closed, the voltage is switched to the standby automatic switching device, thus simulating the backup voltage circuit of standby automatic switching. ④ The standby self-switching device operates correctly after meeting the operating conditions, outputs the closing contacts of KC1 and KC2, and closes the analog circuit breakers KM3 and KM4 of the standby power supply. Through the above introduction, the cooperation between the simulated circuit breaker and the voltage, current, switching part and the tripping and resetting part of the standby automatic switching device can reliably verify the action logic of the "standby automatic switching device" without stopping the primary equipment.
