Test method and test equipment for circuit breaker

Abstract

A circuit breaker testing device, which includes a rotary platform for carrying the circuit breaker and testing devices arranged around the rotary platform, the rotary platform is provided with a plurality of stations that cooperate with the testing device, and the rotary platform is provided with a fixed The test fixture of the circuit breaker is equipped with an automatic closing device between the test devices. During the movement of the circuit breaker between the test devices, the rotary platform drives the circuit breaker to close the circuit breaker through the automatic closing device, and the rotary platform drives the circuit breaker. During the movement between the test devices, the circuit breaker can be automatically closed by the automatic closing device, which is convenient for the next test device to test the circuit breaker. The circuit breaker will be tested once every time the rotary platform moves at a frequency. The closing operation of the circuit breaker does not need to occupy additional operating frequencies and stations of the slewing platform. The invention also improves a circuit breaker testing method, which has higher testing efficiency and saves space.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a testing method and testing equipment for a circuit breaker. Background technique [0002] An important part of the circuit breaker electrical control system. The circuit breaker generally includes two working states of closing and opening. In the process of testing the circuit breaker, it is necessary to perform closing or opening operations on the circuit breaker through multiple devices For example, when it is necessary to test multiple parameters of the circuit breaker from closing to opening state, after each parameter is tested, an additional device needs to be set up to drive the circuit breaker to reset to the closed state before the next parameter test can be performed. This additional device often takes up an additional station, causing unnecessary waste, and the entire testing process is also relatively cumbersome, and the testing efficiency is also lo...
