Description

technical field [0001] The invention relates to the technical field of electric power facilities, in particular to a data networking monitoring grounding variable arc suppression coil parallel-connected small resistance complete set. Background technique [0002] The arc suppression coil is a kind of compensation device used in the small current grounding system. When a single-phase ground fault occurs in the system, the arc suppression coil generates an inductive current to compensate the ground capacitance current, so that the current passing through the ground point is lower than the intermittent arc or maintains stability. The current value required by the arc can eliminate the arc at the grounding point. [0003] The defects of the existing arc suppression coils are: the existing arc suppression coil devices are relatively single, and are basically operated by a single unit, which will easily lead to insufficient performance of the arc suppression coils, incomplete arc ...

[0004] The existing arc suppressing coil device cannot debug and control the current resistance during operation, and it cannot better ensure stable voltage regulation during operation, resulting in unstable voltage during operation of the device. The existing small Due to the high interference of data collection, the resistance system leads to frequent startups. At the same time, with the continuous development of Internet of Things technology, various power facilities and regional power grids are increasingly becoming an interconnected whole, and their degree of automation is also increasing. Accurate Understanding and monitoring the various working data and operating status of the grounding substation line is the key core of the stability and reliability of the ground substation arc-suppression coil with parallel small resistance complete set of devices. For this reason, we propose a data networking monitoring grounding substation arc-suppression coil The complete set of parallel small resistors integrates arc suppressing coils and small resistors, which is convenient for the maintenance and transformation of power facilities, and at the same time ensures the accuracy of data collection, prevents false transmissions due to data collection errors, and ensures the normal input of small resistors to prevent failures. , the situation of refusal occurs due to the failure of the executive switch
