Difference Analysis of Operation Stability of Vacuum Circuit Breaker in 10KV Power Distribution System

Abstract

As an important part of power transmission and transformation equipment, vacuum circuit breakers have become the core device for protecting and controlling electrical lines in high-voltage electrical equipment. This paper expounds the different types of test methods for the preventive test of high and low voltage distribution rooms. Taking the 10kV high and low voltage distribution system in use as the analysis object, 37 units are randomly selected as samples, and statistical principles are used to analyze differences, extract point estimation and interval Estimating eigenvalues, judging the stability and balance of the overall operation of the vacuum circuit breaker in the power distribution system, and providing a basis for the safe use and preventive testing of the power distribution system.
