Abstract
Single pressure type arc-chutes for breaker, including shell, static contact, moving contact and pull rod, the static contact is connected to enclosure interior, the moving contact is correspondingly connected to below static contact by pull rod, piston is socketed on the outside of the pull rod, piston cylinder is socketed on the outside of the piston, gas chamber is formed between the piston and piston cylinder, the pull rod passes through the through-hole of piston cylinder upper end, and pull rod is connect with piston cylinder, heat collection mouth is equipped between the static contact and moving contact, the heat collection mouth is connected to gas chamber.Compared with prior art, single pressure type arc-chutes for breaker of the utility model, energy when collecting static contact and moving contact generation electric arc by heat collection mouth are used to compressed gas, and structure design is simple, and reduces the use of energy consumption.
Description
Technical field
The utility model relates to field of circuit breakers, in particular to a kind of single pressure type arc-chutes for breaker.
Background technique
Arc-chutes are the contacts around switch, for limiting arc space position and accelerating the device of arc extinction.Tradition
Energy required for arc extinguishing is all from external operating mechanism in arc-chutes, and when arc extinguishing, electric arc produces between static contact and moving contact
Raw heat, which can be collected, carrys out arc extinguishing for pushing equipment compressed gas, can save part energy.
Utility model content
The technical problems to be solved in the utility model is in view of the above shortcomings of the prior art, and to provide a kind of for open circuit
Single pressure type arc-chutes of device.
In order to solve the above technical problems, the technical solution adopted in the utility model is:
For single pressure type arc-chutes of breaker, including shell, static contact, moving contact and pull rod, the static contact connection
In enclosure interior, the moving contact is correspondingly connected to below static contact by pull rod, is socketed with piston on the outside of the pull rod, described
It is socketed with piston cylinder on the outside of piston, forms gas chamber between the piston and piston cylinder, the pull rod passes through the logical of piston cylinder upper end
Hole, and pull rod is connect with piston cylinder, and heat collection mouth, the heat collection mouth and gas are equipped between the static contact and moving contact
Room connection.
Further, arc extinguishing nozzle is equipped between the static contact and moving contact, the arc extinguishing nozzle is connected to piston cylinder
Top.
Compared with prior art, single pressure type arc-chutes for breaker of the utility model, are received by heat collection mouth
Energy when collecting static contact and moving contact generation electric arc is used to compressed gas, and structure design is simple, and reduces the use of energy consumption.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Figure 1, single pressure type arc-chutes of breaker, including shell 1, static contact 2, moving contact 3 and pull rod 4 are used for,
The static contact 2 is connected to inside shell 1, and the moving contact 3 is correspondingly connected to 2 lower section of static contact, the pull rod by pull rod 4
4 outsides are socketed with piston 5, and piston cylinder 6 is socketed on the outside of the piston 5, and gas chamber 7 is formed between the piston 5 and piston cylinder 6,
The pull rod 4 passes through the through-hole of 6 upper end of piston cylinder, and pull rod 4 is connect with piston cylinder 6, and pull rod 4 and external operating mechanism connect
It connects, when closing a floodgate, does not generate electric arc between static contact 2 and moving contact 3 also, pull rod 4 continues to move downward, and is compressed and is lived by pull rod
Plug cylinder 6 generates a part of pressure, compressed gas, when static contact 2 and the generation electric arc of moving contact 3, due to static contact 2 and moving contact
It is equipped with heat collection mouth 8 between 3, and heat collection mouth 8 is connected to gas chamber 7, piston cylinder 6, compression are shunk by the heat of generation
Gas, the energy by collecting electric arc can save mechanism energy consumption.
Further, arc extinguishing nozzle 9 is equipped between the static contact 2 and moving contact 3, the arc extinguishing nozzle 9 is connected to work
High pressure gas is blowed to electric arc by arc extinguishing nozzle 9, and then extinguishes electric arc by 6 top of plug cylinder.
The utility model is not limited to the embodiment described, and those skilled in the art is not departing from the utility model
Spirit is that still may make some modifications or changes, therefore the rights protection scope of the utility model is with claims in the open scope
Subject to the range of restriction.
