Technical Field

The invention belongs to the technical field of direct-current high-voltage switches, and particularly relates to an arc extinguish chamber structure for a direct-current high-voltage switch.

Background

The high-voltage direct-current switch is one of key devices of a direct-current transmission system, is used for switching operation modes and removing faults of the direct-current transmission system, cannot extinguish electric arcs through zero points like an alternating-current system due to the fact that current of the direct-current system does not have natural zero crossing points, and further cuts off the current, so that the extinguishing mode of the electric arcs is a core problem, and the high-voltage direct-current switch is divided into a mechanical direct-current switch, a solid-state direct-current switch and a mixed direct-current switch according to the extinguishing.

However, in the existing arc extinguish chamber structure for the direct-current high-voltage switch, the lower end surface is parallel to the static contact current conducting plate, so that the arc voltage at the static contact plate cannot be further improved, and the problem of insufficient arc voltage is caused.

Disclosure of Invention

In order to overcome the defects of the prior art, the invention provides the arc extinguish chamber structure for the direct-current high-voltage switch, which effectively solves the problems that the arc voltage at the static contact plate cannot be further improved, the arc voltage is insufficient and the gas outlet at the static contact plate is not smooth due to the fact that the lower end surface of the arc extinguish chamber structure for the direct-current high-voltage switch is parallel to the static contact current conducting plate.

In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides an explosion chamber structure for direct current high voltage switch, including first partition panel, logical groove has been seted up to first partition panel bottom, logical groove top is installed second V type piece, first partition panel bottom is connected with first V type piece, first partition panel middle part one side is fixed with first cardboard, first curb plate has been cup jointed in the first cardboard outside, first fixed orifices has been seted up at first curb plate middle part, first partition panel middle part opposite side is fixed with the second cardboard, the second curb plate has been cup jointed in the second cardboard outside, the second fixed orifices has been seted up at second curb plate middle part, the roof is installed on first partition panel top, roof bottom one side is fixed with first splint, the second splint are installed to roof bottom opposite side.

Preferably, a rubber sleeve is sleeved inside the first fixing hole.

Preferably, the first partition plate is a metal member.

Compared with the prior art, the invention has the beneficial effects that:

the lower end surface of the structure of the invention is not parallel to the static contact conducting plate, the arc voltage of the electric arc at the static contact plate is improved, the sufficient arc voltage is ensured, and the air outlet at the static contact plate is smooth.
