Analysis of 3 300 V Explosion-Proof Reactive Power Auto- Compensator Switching Phase in Coal Mine
Abstract：During the process of switching reactive power compensation device, turning on or off switch will interfere with distribution system, which causes the over voltage or surge disturb of the power system, directly influences the safety coal production. In order to improve the power supply quality of underground 3 300 V coal mine, an auto-compensator based on phase select is proposed. Switching technique of phase selecting selects the best switch phase, this can realize smooth transition without impact, effectively weak the effect of electromagnetic transient and ensure the power supply quality at underground coal mine. This device has good effect by lab testing.
