The arc suppressing coil is an adjustable inductance coil installed on the neutral point of the power grid. When a single-phase ground fault occurs in the system, the arc suppressing coil provides inductive current to the earth to compensate the capacitive current existing in the system, and the fault at the fault point The current is reduced to the minimum, preventing various harmful phenomena when the system has a single-phase ground fault, and effectively suppressing ground arcing and ground resonance overvoltage. According to the national standard, the system is guaranteed to run for 2 hours with faults. Arc suppression coil type

Model Description
Technical Parameters
Structural principle description The turn-adjustable arc suppression coil is equipped with multiple taps on the arc suppression coil, and the taps of the arc suppression coil are adjusted by an on-load voltage regulating switch to change the inductance value. When the power grid is running normally, the microcomputer controller calculates the ground capacitance current under the current running state of the power grid through real-time measurement, and adjusts the on-load voltage tap changer according to the preset minimum residual current value or detuning degree. switch to adjust to the required compensation gear, when a single-phase ground fault occurs in the power grid, the residual current at the fault point can be limited within the set range. The overall composition of the Japanese turn-adjusting arc-suppression coil complete set Turn-adjustable arc-suppression coil consists of grounding transformer (used when the system has no neutral point), single-pole isolating switch, lightning arrester, turn-adjustable arc-suppression coil, on-load regulating switch, damping resistance box, current transformer, voltage transformer, The primary system circuit diagram and overall structure of the complete set of devices composed of control panel and controller are shown in the figure.
