AI Technical Summary

Technical Problem

Existing circuit breaker anti-pumping and three-phase inconsistency testing methods require two people to work together, which wastes human resources, risks unreliable contact, involves many test steps that are easy to overlook, and calculates the three-phase inconsistency action time is time-consuming, laborious, and prone to errors.

Method used

Design a fully automatic circuit breaker anti-pumping and three-phase inconsistency test system, including a monitoring device and a control device. The system uses a camera to monitor the circuit breaker position in real time, a biological monitoring alarm to prevent personnel from approaching, and realizes automatic opening and closing control of the circuit breaker through a switch interface and a processing module. An FPGA chip is used for logic judgment and control.

Benefits of technology

It enables single-person operation of circuit breaker testing, simplifies wiring, enhances safety, improves the accuracy and convenience of test results, avoids the risks of DC grounding and accidental contact, and reduces waste of human resources and calculation errors.

Abstract

This invention discloses a fully automatic circuit breaker anti-pumping and three-phase inconsistency testing system and its operating method, relating to the field of power system testing. Traditional anti-pumping testing methods require two people, wasting manpower and posing safety risks. This invention includes a monitoring device and a control device communicatively connected to the monitoring device. The monitoring device includes a camera for monitoring the circuit breaker, a position adjustment mechanism for adjusting the camera's position, and a bio-monitoring alarm for triggering an alarm when personnel approach. The control device includes a switching interface connected to the circuit breaker, a switching processing module connected to the switching interface, a touch screen for display and human-machine interaction, a communication module connected to the monitoring device, and a controller connected to the switching processing module, touch screen, and communication module. This technical solution is compact and lightweight, can be operated by a single person, and ensures safe testing.
