Embodiment Construction

[0011] see picture 1, figure 2 , image 3 , Figure 4 , The present invention includes a cylindrical insulating housing 1 and an operating mechanism. The housing 1 is provided with a moving contact 2, a static contact 3, 11, and a grounding contact 4. The moving contact 2 is installed on the main shaft 10, and the static contact 3 11. The ground contact 4 is connected to the inner wall of the housing 1, the static contacts 3 and 11 are respectively distributed on both sides of the moving contact 2, the static contact 3 is connected to the incoming terminal 5, and the static contact 11 is connected to the outgoing terminal 9 The main shaft 10 extends out of the housing 1 through a dynamic sealing system and is connected with the operating mechanism 7. The housing 1 is filled with sulfur hexafluoride, and the cylindrical insulating housing 1 is a die-cast cylindrical whole. The dynamic sealing system includes a transparent cover 6, see image 3 , Figure 4 , The transparent cover 6 i...

Abstract

The disclosed switch includes a cylindrical insulation shell body and operation mechanism. Moving contact, static contacts and grounded contact are setup inside the shell body. The said moving contact is installed on the principal axis. The static contacts and grounded contact are connected to inner wall of the shell body. The static contacts are located at two sides of the moving contact. One side of the static contacts is connected to input terminal, and the other side is connected to the output terminal. Through dynamic seal system, the principal axis is extended out of the shell body and is connected to the operation mechanism. Sulphur hexafluoride is filled inside the shell body. Characters are that the cylindrical insulation shell body is a die casting cylindrical whole.

Description

(1) Technical field [0001] The invention relates to an electrical switch, in particular to an indoor AC high-voltage enclosed load switch. (2) Background technology [0002] The existing indoor AC high voltage enclosed load switch includes a cylindrical insulating shell and an operating mechanism. The shell is provided with a moving contact, a static contact and a grounding contact, and the moving contact is installed on the main shaft. The static contact and the grounding contact are connected to the inner wall of the housing and distributed on the side of the moving contact. The main shaft extends out of the housing through a dynamic sealing system and is connected to the operating mechanism. The housing is filled with hexafluoride sulfur. The shortcoming of this load switch is that its cylindrical insulating shell is connected by half-circular tanks. Due to the large joint sealing surface between the two semi-circular tanks, it is difficult to ensure the sealing performance an...
