An electrical control cabinet integrating circuit breaker test and debugging functions

Abstract

The invention relates to an electric control cabinet integrated with circuit breaker test and debugging functions. The electric control cabinet includes a control room terminal box and a station terminal box. The control room terminal box includes a control room terminal box body and a control room terminal cover plate matched with the control room terminal box body. The control room terminal boxbody has a built-in control room control circuit board. The control room control circuit board is connected with a circuit breaker mechanical characteristic tester and an external power supply througha control room jack unit. The station terminal box includes a station terminal box body and a station terminal box cover plate matched with the station terminal box body. The station terminal box body has a built-in station control circuit board. The station control circuit board is also connected with upper and lower contacts of a circuit breaker, a circuit breaker mechanism box secondary circuit terminal block, an angle sensor, an external power supply an external grounding grid through a station jack unit. The electric control cabinet of the invention integrates the circuit breaker test and debugging functions, improves the work efficiency, and reduces the error rate of the wiring.

Description

technical field [0001] The invention relates to the field of circuit breaker testing and debugging, in particular to an electrical control cabinet integrating circuit breaker testing and debugging functions. Background technique [0002] The existing technical solution is: during the debugging stage of the circuit breaker, when measuring the stroke of the circuit breaker body, it is necessary to use a simple light fitting and a connection line (hereinafter referred to as the connection line) connected to the dynamic and static contacts of the circuit breaker to connect, and the total It needs to be wired three times; when adjusting the circuit breaker body to the light, one person is responsible for adjusting the body stroke, and the other person needs to go to the simple light fitting to understand the change of the display light and then adjust the four-linkage. Walking back and forth requires wiring once , and time-consuming and labor-intensive; when performing energy sto...

AI Technical Summary

Problems solved by technology

[0004] 1. Repeated wiring takes more time

[0005] 2. The three-phase power supply needs to be quoted from the power panel, which is extremely inconvenient and increases the risk of power consumption

[0006] 3. After interrupting the circuit breaker debugging and experiment, the equipment and instruments need to be put into the warehouse, and then when debugging or experimenting, the instruments and wiring need to be moved again, which wastes a lot of time

[0008] 5. The wiring is confusing, which may increase the error rate of wiring
