Embodiment Construction

[0028] Attached below Figure 1-4 The present invention is further illustrated with specific examples.

[0029] like figure 1 As shown, the main structure of an arc-proof contact is shown. An arc-proof contact includes a contact body 1, and the contact body 1 includes a static conductive rod 10 and a movable conductive rod 11 that are axially butted when conducting electricity. When in use, the movable conductive rod 11 moves relative to the static conductive rod 10 in the axial direction until the two contact each other and become energized, or separate from each other to de-energize, the butt end of the static conductive rod 10 is detachably installed with a static contact Assembly 100 for replacement, the butt end of the movable conductive rod 11 is detachably installed with the movable contact assembly 110 for replacement, the static contact assembly 100 and the movable contact assembly 110 are arranged opposite and contact each other when conducting electricity.

Abstract

The invention relates to an anti-arc contact in the technical field of electric power contact. The butt end of the rod is detachably installed with a moving contact assembly, the static contact assembly and the moving contact assembly are arranged oppositely, and are in contact with each other when conducting electricity; the static contact assembly includes a static contact seat, a static contact The butt end of the seat and the static conductive rod is detachably connected, and the static conductive set is detachably set on the static contact seat; the moving contact assembly includes a moving contact seat, and the butt end of the moving contact seat and the moving conductive rod The connection is disassembled, and a moving conductive set is detachably sleeved on the moving contact seat. In order to solve the problems in the prior art that the contacts are easily damaged and the anti-arc effect is poor.

Description

technical field [0001] The invention relates to the technical field of power contact, in particular to an arc-proof contact. Background technique [0002] Arc is a gas discharge phenomenon, an instantaneous spark generated by a current passing through some insulating medium (such as air), an arc is a self-sustaining gas conduction, and most of its carriers are electrons generated by primary electron emission, and the contact metal Electrons escape from the surface due to primary electron emission (thermoionic emission, field emission or photoemission), and gas atoms or molecules in the gap will generate electrons and ions due to ionization (collision ionization, photoionization and thermal ionization). [0003] At present, an arc will be generated during the use of the power distribution switch, and the generation of the arc will easily cause the contacts of the power distribution switch to be damaged during use. The contacts of the existing power distribution switch are les...
