Product Description

High Voltage Circuit Breaker Mechanical Characteristic Tester

Introduction

A circuit breaker analyzer is an instrument used to check and evaluate the function of a circuit breaker to ensure the safety and reliability of its operation in an electrical system. It is usually used for parameter detection and analysis of AC high-voltage switches such as AC high-voltage circuit breakers, load switches, and disconnectors.
 

Advantages

(1) The analyzer integrates a vibration test function, providing a new method for testing the mechanical characteristics of circuit breakers, which is simpler and more effective.
(2) The test results contain more information about the circuit breaker. For circuit breakers with potential failure risks or failures, the cause of the failure can be quickly located.
(3) There is no need to change the original wiring connection method of the circuit breaker to achieve live detection of the mechanical characteristics of the circuit breaker.
(4) The arc extinguishing contact analysis module allows users to automatically evaluate the wear degree of the arc extinguishing contacts inside the circuit breaker without disassembling the circuit breaker.
(5) The circuit breaker circuit resistance measurement can be completed with the instrument alone, and users do not need to purchase a separate circuit resistance tester, which reduces the weight of the on-site test instrument and saves user costs.

Why do we need to test circuit breakers regularly?

When a fault such as a short circuit or current overload is detected by a protective relay, a trip impulse is sent to the circuit
breaker. The circuit breaker must function as specified and interrupt the current as soon as possible or severe damage may occur.The damage caused by a malfunctioning circuit breaker can often be catastrophic, resulting in significant damage to the electrical system.
Given that circuit breakers may be inactive for months or even years prior to a fault, a regime of circuit breaker testing is an important safety factor. Proper functionality of a breaker is reliant on a number of individual components that have to be calibrated and tested at regular intervals to ensure the complete and successful breaking of the circuit when triggered. Poorly maintained circuit breakers may not activate after receiving the trigger signal sent by the protective.
