Embodiment Construction

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

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

[0034] The terminal block includes a columnar inner core conductor 7, the upper end of the inner core conductor 7 is an outer connection end for connecting with an external test equipment, and the outer connection end is provided with a threaded hole for ...

Abstract

The invention relates to the field of circuit breaker testing, in particular to a tool for breaker operation test. The tool comprises a sealing plate used for being fixed to a wire inlet or a wire outlet of a circuit breaker shell. The sealing plate is fixedly provided with a terminal base which is used for transmitting an electric signal on an inlet wire conductor or an outlet wire conductor in the circuit breaker to the outside. The terminal base is provided with an outer connecting end used for being connected with an external test device and an inner connecting end used for being connectedwith an inlet wire conductor or an outlet wire conductor. The inner connecting end is provided with the plug-in conductive structure used for plug-in conduction with the inlet wire conductor or the outlet wire conductor, the plug-in conductive structure comprises the elastic conductor used for elastic conductive contact with the inlet wire conductor or the outlet wire conductor, and compared withthe prior art, the plug-in conductive structure does not need to be fixed through a bolt, simplifies the preparation process in the early stage of a 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 test. Background technique [0002] Currently, when performing operational tests on circuit breakers, such as figure 1 As shown, it is necessary to seal the wire inlet 111 and the wire outlet 113, fill in a certain pressure of sulfur hexafluoride insulating gas, and conduct insulation resistance measurement and other operations by connecting the conductors of the inlet and outlet wires of the circuit breaker 112 with the joints of the test equipment. Therefore, there is a need for a test tool that can close the wire inlet 111 and the wire outlet 113 and can lead the wire inlet and outlet conductors out. [0003] The Chinese utility model patent with the authorized notification number CN205539379U discloses a tool for testing the mechanical characteristics of circuit breakers, including a sealing plate fixed on the flange of the circu...
