本发明涉及光纤光栅传感技术领域，涉及一种基于光纤光栅的温度传感器，尤其涉及一种在高电压、高电磁等恶劣环境下有效连接光纤光栅的耐温耐压光纤适配器及其制作检测工艺。The present invention relates to the field of optical fiber grating sensing technology, relates to a temperature sensor based on optical fiber grating, in particular to a temperature-resistant and pressure-resistant optical fiber adapter for effectively connecting optical fiber gratings under high voltage, high electromagnetic and other harsh environments and its production and detection process .
背景技术Background technique
电力设备在运行过程中，受电、热、自然环境、长期工作、超负荷工作等因素影响，容易导致设备老化、性能下降，可靠性降低，甚至危及系统的安全运行。如变压器、开关柜、环网柜触头或电缆接头等位置因接触不良，接触电阻增大，导致触头温升过高，引起火灾、爆炸等事故。因此，有必要对电力设备进行实时、在线监测，及时发现故障，将事故消除在萌芽状态，延长设备使用寿命。一般采用传感器对其电力设备进行安全监测。During the operation of power equipment, it is affected by factors such as electricity, heat, natural environment, long-term work, overload work, etc., which can easily lead to equipment aging, performance degradation, lower reliability, and even endanger the safe operation of the system. For example, due to poor contact in transformers, switch cabinets, ring network cabinet contacts or cable joints, the contact resistance increases, resulting in excessive temperature rise of the contacts, causing fires, explosions and other accidents. Therefore, it is necessary to carry out real-time and online monitoring of power equipment, find faults in time, eliminate accidents in the bud, and prolong the service life of equipment. Generally, sensors are used to monitor the safety of its power equipment.
然而传统的温度传感器不能同时满足稳定性、耐久性、既可粘贴也可埋入、分布式在线数据采集等要求。光纤光栅是一种性能良好的温度传感元件，无论在技术成熟度，还是成本上都已经取得了实质的突破。光纤光栅用于温度传感的主要优点体现在：不受电磁干扰，电绝缘性好；耐久性好；质量轻、体积轻、对结构影响小、易于布置；既可以实现点测量；绝对测量；节省线路，只用一根线就可以传送温度状态信号；信号、数据可多路传输，便于与计算机连接，单位长度上信号衰减小；灵敏度高，精度高；频带宽，信噪比高等。因此，光纤光栅技术有着广阔的应用前景。考虑到裸光纤光栅特别脆弱，尤其是抗剪能力较差，直接将其作为温度传感器无法胜任传感器布设以及恶劣的服役环境，因此，对裸光纤光栅进行封装处理，是将光纤光栅作为温度传感器推广应用的一个必然环节。However, traditional temperature sensors cannot meet the requirements of stability, durability, pasting or embedding, and distributed online data collection at the same time. Fiber Bragg Grating is a temperature sensing element with good performance, and has made substantial breakthroughs in terms of technology maturity and cost. The main advantages of fiber gratings for temperature sensing are: no electromagnetic interference, good electrical insulation; good durability; light weight, light volume, small impact on the structure, easy to arrange; both point measurement and absolute measurement; Save lines, only one line can be used to transmit temperature status signals; signals and data can be multiplexed, easy to connect with a computer, and the signal attenuation per unit length is small; high sensitivity, high precision; wide frequency band, high signal-to-noise ratio, etc. Therefore, fiber grating technology has broad application prospects. Considering that the bare fiber grating is particularly fragile, especially the poor shear resistance, directly using it as a temperature sensor is not suitable for sensor layout and harsh service environment. Therefore, packaging the bare fiber grating is to promote the fiber grating as a temperature sensor. An inevitable part of the application.
光纤适配器是光纤与光纤之间进行可拆卸（活动）连接的器件，它是把光纤的两个端面精密对接起来，以使发射光纤输出的光能量能最大限度地耦合到接收光纤中去，并使由于其介入光链路而对系统造成的影响减到最小，这是光纤连接器的基本要求。在一定程度上，光纤连接器也影响了光传输系统的可靠性和各项性能。但是现有的光纤适配器虽然有价格低廉，安装方便，互换性和重复性能良好等优点；但均存在只能在普通工况下工作，不耐压，不耐温不能适应恶劣环境中；且现有的光纤适配器的结构基本如下，由壳体（对C形环和固定件起保护作用，同时可以固定在所需的物体上，并有相应的不同的接口形式与光纤跳线相连接），C形环（陶瓷，光纤插头在C形环内接触，其起到调整，定位等作用），固定件（固定C形环），等组成；有些适配器内包含有弹簧等调整件，起到调整定位的作用，在此不详细列出。现有技术下的光纤适配器均为开放式结构，不具备密封条件，且使用温度范围小，不能满足电力行业中的各种恶劣环境中的使用。Optical fiber adapter is a device for detachable (movable) connection between optical fiber and optical fiber. It precisely butts the two end faces of optical fiber so that the optical energy output by the transmitting optical fiber can be coupled to the receiving optical fiber to the maximum extent. Minimizing the impact on the system due to its intervention in the optical link is a basic requirement for fiber optic connectors. To a certain extent, fiber optic connectors also affect the reliability and performance of optical transmission systems. However, although the existing optical fiber adapters have the advantages of low price, convenient installation, good interchangeability and repeatability; but they all have the disadvantages that they can only work under normal working conditions, are not resistant to pressure and temperature, and cannot adapt to harsh environments; and The structure of existing fiber optic adapters is basically as follows, consisting of a housing (which protects the C-shaped ring and the fixing part, and can be fixed on the required object at the same time, and has corresponding different interface forms to connect with the fiber jumper) , C-shaped ring (ceramic, fiber optic plugs are in contact with the C-shaped ring, which plays the role of adjustment, positioning, etc.), fixing parts (fixing the C-shaped ring), etc.; some adapters contain adjustment parts such as springs, which play a role The function of adjusting positioning is not listed in detail here. The optical fiber adapters in the prior art are all open structures, do not have sealing conditions, and have a small operating temperature range, which cannot be used in various harsh environments in the power industry.
