A circuit breaker unlocking power supply wiring device for mechanical characteristic test of handcart circuit breaker

Abstract

The invention provides a circuit breaker unlocking power supply wiring device for testing mechanical properties of a handcart circuit breaker, which comprises an AC / DC conversion plug and two binding posts, wherein the AC / DC conversion plug is used for connecting a secondary aviation plug of the handcart circuit breaker, the two binding posts are used for connecting a circuit breaker unlocking power supply, and the two binding posts are respectively connected with corresponding incoming line terminals of the AC / DC conversion plug through a cable. The circuit breaker unlocking power supply wiring device can provide an unlocking power supply for testing the mechanical properties of the handcart circuit breaker through the currently connected unlocking power supply, and enables the handcart circuit breaker to be electrified to remove mechanical locking thereof, thereby being convenient to improve the test efficiency. The circuit breaker unlocking power supply wiring device for testing the mechanical properties of the handcart circuit breaker further comprises a box body, a rotating shaft, a supporting plate and a barrel body, wherein the box body, the rotating shaft, the supporting plate and the barrel body form a pay-off structure with a specific structure. Application of the pay-off structure facilitates collection and release of the two cables under the premise of not affecting the test and helps to keep the neatness of wiring at the test field.

Description

technical field [0001] The invention relates to the field of auxiliary equipment for testing the mechanical characteristics of handcart circuit breakers, in particular to a circuit breaker unlocking power supply wiring device for testing the mechanical characteristics of handcart circuit breakers. The handcart breaker connection unlocks the convenience of power. Background technique [0002] High-voltage circuit breakers are important control devices in power systems. When the power system is running normally, it can cut off and connect the lines and the no-load and load currents of various electrical equipment; when the power system fails, it cooperates with the relay protection to quickly cut off the fault current to prevent expansion scope of the accident. Therefore, the quality of the high-voltage circuit breaker directly affects the safe operation of the power system. [0003] There are a large number of high-voltage circuit breakers in the power grid, and the operat...
