Description

Overview

In power system of 6-66KV, when capacitive current associated with single phase ground fault excess 10A (It is 30A in 6-10KV cable circuit system), arc suppression coil device should be adopted to prevent arc grounding, remove earth fault and improve power supply quality.

MRD-XHZ Arc-Suppression Coil with Adjustable Tuning Compensation Device employs standard industrial computer system, bus-organization, multilayer PCB and full-color LCD screen to provide system with stable operation, visual display, strong anti-interference capability, perfect parameter settings and information query function.

MRD-XHZ Arc-Suppression Coil with Adjustable Tuning Compensation Device adopts 6-110KV voltage grade and is widely used in transformer substations of large factories and mines.

Features
1. Controller adopts industrial computer platforms, dual-CPU framework and multilayer PCB processing to ensure stable and reliable operation
2. With full-color LCD screen, the running state, system capacitive current, neutral voltage, neutral current, out-of-resonance degree, residual current and fault-times of single-phase can be displayed, set and inquired conveniently
3. The adjusting range is wide, between 0-100% rated current and also accurate and quick
4. Embedded high voltage grounding line selection module employs residual incremental method and active power method making the line selection accurately and quickly
5. Equipped with RS232 and RS485 communication interface, our product can communicate with supervising computer to achieve signal teleportation
6. Our product can realize acoustic alarm of single-phase earth fault
7. Equipped with standard parallel printer, our product can finish data printing and ground information printing
8. Our product possess one system controlling two sets device function, namely, two sets of arc suppression coil in the same system can transform automatically along with the system operation
