GB/T 1094.6-2011 Arc Suppression Reactor Coil Grounding Device

Complete Set Of Arc Suppression Coil Grounding Device,Current Limiting Reactors

1. Overview of Complete Set Of Arc Suppression Coil Grounding Device,Current Limiting Reactors

The complete set of arc suppression coil grounding device is used in the power grid where the single-phase ground fault capacitance current of the system exceeds 10A. The main equipment included in the device includes: dry-type grounding transformer, dry-type arc suppression coil, vacuum on-load switch, controller, damping resistor Box, parallel middle resistance box (optional), isolating switch, voltage transformer, lightning arrester, etc.

2. Purpose of Complete Set Of Arc Suppression Coil Grounding Device,Current Limiting Reactors

The main function of the arc suppression coil grounding device is to automatically measure the capacitance current of the system in the normal operation of the grid system, and automatically enter the compensation state when the system is single-phase grounded, and output and system single-phase between the neutral point of the system and the ground. The inductive compensation current corresponding to the grounding capacitance current can limit the grounding current and eliminate the grounding arc. After the grounding fault is eliminated, it will automatically exit the compensation state.
