Embodiment Construction

[0009] Embodiments are described in detail with reference to the accompanying drawings. An air switch breaker, including an insulating terminal 1 and a rod body 2, the insulating terminal 1 is fixedly connected to the rod body 2, and the end side of the insulating terminal 1 is provided with an outer arc-shaped hook matching the air switch 3. In this way, during use, according to the arc-shaped movement characteristics of the air switch, ensure that the outside of the hook in contact with the air switch is arc-shaped, which is convenient for operation. The other side of the end of the insulating terminal 1 is provided with a V-shaped groove 4 to ensure The air switch can be closed reliably.

[0010] The rod body 2 of the present invention includes an inner rod 5 and an outer rod 6 , wherein the inner rod 5 is inserted into the rod body of the outer rod 6 and is fixedly connected by a fixed connecting sleeve 7 fixed to the end of the outer rod 6 . The rod body 2 is made of sta...

Abstract

The invention discloses an air switch breaker. According to main points of the technical scheme, the air switch breaker comprises an insulation end head and a rod body, wherein the insulation end head is fixedly connected with the rod body, one side at a tail end of the insulation end head is provided with an outer arc hook in matching with an air switch, and the other side is provided with a V-shaped groove. The air switch breaker completely solves a problem of influence of insufficient height on real-time closing/opening of the air switch and can further be used in a household air switch.

Description

technical field [0001] The invention relates to a device for opening and closing an air switch, in particular to an air switch breaker. Background technique [0002] The air switch behind the relay protection screen needs to be disconnected and closed during switching operation of the substation. Due to the high position of the air switch, short duty personnel often need to stand on a stool to realize the disconnection of the air switch, which brings a lot of trouble to the work. Many inconveniences. Contents of the invention [0003] In order to overcome the disadvantages of the prior art, the present invention provides an air switch breaker with simple structure and convenient use. [0004] The technical solution of the present invention is: an air switch breaker, including an insulating terminal and a rod body, characterized in that: the insulating terminal is fixedly connected to the rod body, and the end side of the insulating terminal is provided with an air The sw...
