Abstract

The invention discloses a double-contact type load switch. The double-contact type load switch comprises a shell, a first contact part which is arranged on the peripheral wall of the shell, wherein afirst contact and a second contact are arranged on the first contact piece in a protruding mode, the first contact and the second contact protrude in the axial direction of the shell, and the first contact protrudes out of the second contact; a second contact part which is rotationally connected in the shell, can rotate around the axis of the shell and is used for being connected with the first contact and the second contact in a matched mode, wherein the second contact is closer to the second contact than the first contact. The first contact part is provided with the first contact and the second contact, and the first contact and the second contact are subjected to arcing, so that the separation distance between the first contact and the second contact and the second contact part can be shortened, and the arc extinguishing speed is increased; and the second contact is closer to the second contact than the first contact, so that the damage degree of the electric arc to the first contact can be reduced.

Description

technical field [0001] The invention relates to the technical field of switches, in particular to a double-contact load switch. Background technique [0002] The load switch has an arc extinguishing function, which is often used in high-voltage power grids to ensure the safety of the switch when it is opened and closed, and to reduce the safety problems caused by the arc. [0003] When the load switch in the past is used, due to the slow arc extinguishing speed, it is easy to cause safety accidents such as fire or explosion, which cannot guarantee safety and is not conducive to production. Contents of the invention [0004] The present invention aims to solve at least one of the technical problems existing in the prior art. For this reason, the present invention proposes a double-contact load switch, which can speed up the arc extinguishing speed and ensure safety. [0005] A double-contact load switch according to an embodiment of the first aspect of the present inventi...
