Embodiment Construction

[0032] The specific embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0033] Example 1 of the tooling for the circuit breaker operation test, such as figure 2 image 3 As shown in the figure, it includes the sealing plate 4 fixed on the wire inlet or outlet of the circuit breaker casing. Since the structure of the sealing plate 4 fixed on the wire inlet or outlet is the same, the wire inlet is taken as an example here. The plate 4 is fixed on the flange plate 1 of the line inlet, and the sealing plate 4 is fixed with a terminal block for conducting the electrical signals on the incoming line conductor or the outgoing line conductor in the circuit breaker to the outside.

[0034] The terminal block includes a cylindrical inner core conductor 7, the upper end of the inner core conductor 7 is an outer connecting end for connecting with external testing equipment, and the outer connecting end is provided with a th...

Abstract

The present invention relates to the field of circuit breaker testing, in particular to a tooling for circuit breaker operation test, which includes a sealing plate for fixing on the line inlet or line outlet of the circuit breaker housing. The electrical signal on the incoming conductor or outgoing conductor is transmitted to the external terminal block, and the terminal block has an external connection end for connecting with external test equipment and an internal connection end for connecting with the incoming or outgoing conductor. The internal connection The end is provided with a plug-in conductive structure for plugging and conducting with the incoming conductor or outgoing conductor. The plug-in conductive structure includes an elastic conductor for elastic conductive contact with the incoming conductor or outgoing conductor. Compared with the existing technology, there is no It needs to be fixed by bolts, which simplifies the preparation process in the early stage of the test and improves the test efficiency.

Description

technical field [0001] The invention relates to the field of circuit breaker testing, in particular to a tooling for circuit breaker operation testing. Background technique [0002] At present, when the circuit breaker is tested for operation, such as figure 1 As shown, it is necessary to seal the inlet 111 and outlet 113, fill with a certain pressure of sulfur hexafluoride insulating gas, and connect the conductor of the inlet and outlet of the circuit breaker 112 to the connector of the test equipment to perform operations such as insulation resistance measurement. Therefore, there is a need for a test tool that can seal the wire inlet 111 and the wire outlet 113 and can lead out the incoming and outgoing wire conductors. [0003] The Chinese utility model patent with the authorization announcement number CN205539379U discloses a tool for testing the mechanical characteristics of a circuit breaker, including a sealing plate fixed on the flange of the circuit breaker shell...
