Embodiment Construction

[0031] Example of a circuit breaker:

[0032] The circuit breaker includes an energized conductor 6 and a contact finger assembly installed on the energized conductor 6. The electrical connection or de-energization of the energized conductor 6 is realized through the plug-in fit of the contact finger assembly. The specific structure of the circuit breaker is as follows: Figure 1~Figure 4 shown. The contact finger assembly includes a step-shaped contact seat 3 composed of two concentric cylinders. The middle part of the contact seat 3 is provided with a bolt perforation 33 for connecting with the corresponding threaded hole on the current conductor 6. The contact seat 3 is fixedly connected by a bolt 5. energized conductor 6. The diameter of the upper cylinder 31 of the contact seat 3 is smaller, and the diameter of the lower cylinder 32 is larger. The upper end surface of the lower cylinder beyond the upper cylinder forms a shoulder 34 of the contact seat 3, and the shoulder...

Abstract

The invention relates to a contact finger plate, a contact finger plate processing method, a contact finger, a contact finger assembly, and a circuit breaker, thereby solving a problem of high processing and manufacturing costs in the prior art. The contact finger plate is formed by compressing a panel, so that the material utilization rate is improved; no extra manufacturing die or forging processing equipment needs to configure, so that the production manufacturing cost and production manufacturing period of the contact finger are reduced substantially.

Description

technical field [0001] The invention relates to a contact finger, a processing method for the contact finger, a contact finger, a contact finger assembly and a circuit breaker. Background technique [0002] In the field of high-voltage switchgear, the switching on and off of the high-voltage switch depends on the cooperation of the dynamic and static contact finger components, so the contact finger component is one of the most important components in the field of high-voltage switchgear. The contact finger assembly includes the contact finger and the contact seat used to fix the contact finger. For some self-supporting contact fingers including the base body and the elastic contact piece, since there is a gap between the contact fingers, it is necessary to set a shielding cover around the contact finger to Control the airflow and electric field at the gap. In order to ensure a reliable electrical connection between the elastic contact piece and the corresponding contact, th...
