Problems solved by technology

The non-full-phase function needs to test a total of twelve circuit breaker auxiliary nodes, the number of actions is large, and it is easy to miss
[0004] In the traditional method, three people are required to cooperate to complete the work, which requires a large number of people, is difficult to cooperate, and takes a long time. Multiple tests will cause damage to the circuit breaker
Once the short circuit jumps and the closing circuit is the outlet, it is impossible to check the correctness of the wiring, which will easily cause the two sets of control circuits to short-circuit each other and DC grounding. At the same time, this method requires multiple manual closings, which greatly increases the number of circuit breaker operations. Affect the life of the circuit breaker
Mistakes in the non-full-phase function test of the circuit breaker will cause accidents: when the non-full-phase function pressure plate is put into use, the circuit breaker will trip directly, causing the line to trip by mistake; Short circuit, resulting in the situation that the two sets of control circuits are both grounded, which eventually leads to misoperation of the busbar protection and tripping of the busbar by mistake

Abstract

The invention discloses a breaker non-full-phase function testing device which comprises a power supply module, an alarm module, an output module, a micro-processing unit (MCU), a display module, a test button and a time module. The power supply module, the alarm module, the output module, the display module, the test button and the time module are connected with the micro-processing unit (MCU), and the test button is used for driving the micro-processing unit (MCU) to start a task. The device is used for driving the micro-processing unit (MCU) to start a task. By using the device, the problemthat the inspection work is completed by three persons in cooperation in the past is solved, one person can independently complete the inspection work, and the working efficiency is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of relay protection, and in particular relates to a non-full-phase functional testing device for a circuit breaker. Background technique [0002] At present, the non-full-phase function test of the circuit breaker is an indispensable inspection content in the infrastructure acceptance and maintenance pre-test of the circuit breaker in the relay protection profession. [0003] The staff continues to use the traditional method for inspection, and at least three people are required to cooperate to complete the work. One person performs non-full-phase pressure plate switching and switch opening and closing at the HSBC cabinet or terminal box, and one person monitors it. At the same time, another person needs to check the indication position of the operation box and the recording signal in front of the protective screen. The traditional non-full-phase test requires a large number of people, which is dangerous, a...
