DIGITAL CONTROLLING SYSTEM FOR MONITORING INTERNAL ABNORMAL STATE OF SWITCHGEAR

摘要

PURPOSE: A digital control system for monitoring the state of an internal switchboard is provided to sense an abnormal state on time by installing a temperature sensor and a flame sensor inside of a switchboard. CONSTITUTION: A temperature sensor(25) inputs measured temperature data into a temperature measurement terminal. The temperature sensor is installed in the connection part of a bus bar and a breaker in a non-contact way. An operation sensor(21) inputs detected operation data into an operation input terminal. A flame sensor(26) inputs detected flame data into a flame sensing terminal. A digital controller(100) operates an alarm issue device and an automatic extinguishing device by sensing an abnormal state.
