Research on Relay Protection Technology for Lighting Load in High Voltage Power Supply System
CHEN Xiangjie
Abstract：The safe and stable operation of lighting load in high-voltage power supply system is directly related to the operation environment and personal safety on industrial site.The relay protection technology of lighting load is the key link to ensure the reliability of its power supply.This paper takes the high-voltage power supply system as the research object,analyzes the application status of existing protection technology,systematically sorts out the shortcomings of traditional technology in terms of practicability and response sensitivity,and then proposes a systematic and operable scheme.The anti-interference ability and quick power-offresponse ability of the lighting system are improved by clarifying the protection objectives,selecting relay equipment,optimizing the setting calculation and coordinating the strategy.
