Embodiment Construction

[0014] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.

[0015] Such as Figure 1-3 As shown, a moving and static contact plug-and-pull limit mechanism includes a static contact 1 and a moving contact 2, and a gear lever 3 is connected to the upper inner side of the static contact 1; specifically, the static contact 1 A connecting plate 11 is extended downward; a pin shaft 12 is connected with the connecting plate 11; the gear rod 3 is sleeved on the pin shaft 12, and can figure 1 Rotate freely around the pin shaft 12 in the plane.

[0016] One end of the gear lever 3 is connected to the static contact 1, and the other end is a free end;

[0017] The insertion of the moving contact 2 makes the gear lever 3 be forced to rotate inwardly and upwardly relative to the static contact 1. When the moving contact 2 and the static contact 1 are connected in place, the rotation of the gear lever 3 is not aff...

Abstract

The invention relates to an insertion and extraction limiting mechanism for a moving contact and a stationary contact. The mechanism comprises the stationary contact and the moving contact, wherein astop lever is connected with the top of the inner side of the stationary contact, and can freely rotate around the joint between the stop lever and the stationary contact; the stop lever is forced torotate when the moving contact is inserted; and after the moving contact and the stationary contact are properly connected, the stop lever rotates until the lower end of the stop lever falls behind the moving contact. The mechanism provided by the invention has the advantage that the moving contact can be prevented from being extracted due to misoperation.

Description

technical field [0001] The invention relates to a high-voltage circuit breaker dynamic and static contact connection technology, and specifically discloses a dynamic and static contact insertion and removal limiting mechanism. Background technique [0002] High-voltage isolating switch is an important switching device in the electrical system of power plants and substations, and it needs to be used in conjunction with high-voltage circuit breakers. [0003] In the circuit breaker, the plugging and unplugging of the moving and static contacts is used to realize the connection of the circuit; in practical applications, the moving contact will be pulled out due to the operator's misoperation, that is, the power will be cut off suddenly, and arc light will be generated, which poses a safety hazard . Contents of the invention [0004] The purpose of the present invention is: to solve the above problems, to provide a simple structure, easy to operate and use of the movable and ...
