Disconnecting switch and conducting loop structure thereof

Abstract

The invention discloses a conducting loop structure. The conducting loop structure is characterized in that the sidewall of one side of a fixed contact, close to a rotating arm, comprises a first wall and a second wall which are distributed up and down; one end of the first wall is fixedly connected with the upper wall of the fixed contact while the other end of the first wall extends into the fixed contact; a first compressing spring is arranged between the other end of the first wall and the upper wall, and two ends of the first compressing spring are respectively connected with the upper wall and the first wall; one end of the second wall is fixedly connected with the lower wall of the fixed contact while the other end of the second wall extends into the fixed contact; a second compressing spring is arranged between the other end of the second wall and the upper wall, and two ends of the second compressing spring are respectively connected with the lower wall and the second wall; a clamping groove used for containing a moving contract is formed between the first wall and the second wall; and the moving contract is specifically a conducting plate which can be arranged into the clamping groove in a clamping manner. By adopting the conducting loop structure, the problem that the low switching-in success rate is generated to further impact the safety and stability of equipment and a power grid in running can be solved. The invention also provides a disconnecting switch comprising the conducting loop structure.

Description

technical field [0001] The invention relates to the technical field of high-voltage switches, more specifically, to an isolating switch and its conductive circuit structure. Background technique [0002] Three-column horizontal rotary double-break high-voltage AC isolating switch is widely used in 220kV outdoor power distribution devices to realize electrical isolation. [0003] see Figure 1 to Figure 3 , The isolation switch includes three insulators 04 arranged side by side, the ones on both sides are supporting insulators, the middle one is a rotating insulator, the top of the supporting insulator is provided with a static contact 01, and the top of the rotating insulator is provided with a rotating insulator through a bracket 03. The center line of the rotating arm 02, and the two ends of the rotating arm 02 are provided with movable contacts 05. In the prior art, there are two closing methods, one of which is the contact turning-in type: when the static contact is in ...
