技术领域technical field
本发明涉及电力电缆领域，具体涉及一种内置式高压电缆接头测温装置及方法。The invention relates to the field of power cables, in particular to a built-in high-voltage cable joint temperature measuring device and method.
背景技术Background technique
高压电缆作为城市的血脉，提供着城市生活所需的能量。一旦电缆出现故障，对城市生活造成的影响不可估量。高压电路主要故障位置为高压电缆接头，做好高压电缆接头检测，是确保高压电缆稳定工作的要点。高压电缆检测技术包含温度检测和局放检测，温度检测包含光纤检测和内置温度检测。As the blood of the city, high-voltage cables provide the energy needed for urban life. Once the cable fails, the impact on urban life is immeasurable. The main fault location of the high-voltage circuit is the high-voltage cable connector. Doing a good job in the detection of the high-voltage cable connector is the key point to ensure the stable operation of the high-voltage cable.

公开号为CN103837260A的发明专利公开了一种电缆接头光纤测温装置，线缆接头被上夹板和下夹板通过螺栓夹持，在上夹板上有上变形齿，在平板的下部有下变形齿，在上变形齿与下变形齿之间夹持有信号光纤，信号光纤的另一端与测试单元连接，上变形齿的热膨胀系数大于螺栓的膨胀系数；当线缆接头温度升高后，导致上变形齿变高，从而使上变形齿与下变形齿之间的距离靠近，使信号光纤的微弯曲率增加，导致信号光纤内传输的光信号衰减，则测试单元监测到光信号的变化，并将该变化值传递给处理单元，后者计算出线缆接头温度的变化，并根据变化的大小判断下一步是报警还是继续监测，但是光纤测温检测的是光纤植入电缆结构层所在部位的温度，并非电缆导芯的真实温度，且在电缆入地铺设过程中，因为承受大力牵引和拉伸极易断裂，导致测温功能丧失，因此，在实际应用中光纤测温技术存在很大限制。The invention patent with publication number CN103837260A discloses an optical fiber temperature measurement device for a cable joint. The cable joint is clamped by an upper splint and a lower splint through bolts. The upper splint has upper deformation teeth, and the lower part of the flat plate has lower deformation teeth. A signal optical fiber is clamped between the upper deformation tooth and the lower deformation tooth, and the other end of the signal fiber is connected to the test unit. The thermal expansion coefficient of the upper deformation tooth is greater than that of the bolt; when the temperature of the cable joint increases, the upper deformation is caused The teeth become higher, so that the distance between the upper deformed teeth and the lower deformed teeth is close, which increases the micro-bending rate of the signal fiber and causes the optical signal transmitted in the signal fiber to be attenuated. The change value is passed to the processing unit, which calculates the change in the temperature of the cable joint, and judges whether the next step is to alarm or continue monitoring according to the size of the change, but the optical fiber temperature measurement detects the temperature of the part where the optical fiber is implanted into the cable structure layer. , not the real temperature of the cable guide core, and during the laying process of the cable into the ground, it is easy to break due to strong traction and stretching, resulting in the loss of the temperature measurement function. Therefore, the optical fiber temperature measurement technology has great limitations in practical applications.

The power take-off ring is a new type of power supply device that uses the principle of electromagnetic induction to obtain electrical energy and achieve stable voltage output. It adopts an open design, which is easy to install and operate. The inner diameter of the transformer can be selected according to the diameter of the high-voltage line, and the transformers of different types and specifications can be matched according to the current of the high-voltage line. Power supply shock, with overcurrent protection device, can be used to install on high-voltage cables with a large current range, output stable DC power, with battery intelligent charging and discharging interface, can continue to maintain in the state of insufficient power supply or power failure The device is working normally. The electric energy obtained by the power taking ring provides wireless power supply for the built-in
