Description
Technical field
The utility model relates to a kind of switch arc-control device, specifically a kind of contact-making switch arc-control device.
Background technology
When supply voltage exceedes tens of volt, drop-out current when tens of peace is above, be reduce the space of electric arc to the scaling loss of contact and the expansion of restriction electric arc, usually need the measure taking to strengthen arc extinguishing ability, for this reason and the device adopted is called arc-control device.And existing arc-control device or complex structure, high cost, or arc quenching effect is undesirable, cannot satisfy the demands.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of can the contact-making switch arc-control device of fast arc extinction.
The utility model for solving the problems of the technologies described above adopted technical scheme is: a kind of contact-making switch arc-control device, comprise two connect fixed contact in circuit and one be connected on driving mechanism, and can contact with two fixed contacts under driving mechanism drives simultaneously, thus the moving contact of turning circuit, two described fixed contacts are symmetrical arranged, and be spaced from each other, the contact of two fixed contacts is all towards moving contact, moving contact is laterally crossed between two fixed contacts, and the two ends of moving contact are respectively equipped with the contact contacted with two fixed contacts; Be respectively equipped with an insulation arc extinguishing board in the both sides of two fixed contacts, insulation arc extinguishing board is provided with the slit that the distribution arrangement along moving contact and fixed contact extends, and slit be all corresponding with the contact of moving contact and fixed contact.
Described slit is divided into entrance and arc extinguishing section two parts along its depth direction, entrance is towards moving contact and fixed contact, its width is greater than the diameter of the electric arc formed between moving contact and fixed contact, and the width of arc extinguishing section is less than the diameter of the electric arc formed between moving contact and fixed contact.
The beneficial effects of the utility model are: two symmetrically arranged fixed contacts parallel with the electric arc produced between moving contact, and the sense of current is contrary, thus produce the magnetic field of repelling each other around two electric arcs.This magnetic field forces two electric arc oppositely movements, and is elongated by electric arc, extinguishes to impel it.Further, insulation arc extinguishing board is set respectively in the both sides of two fixed contacts, by the magnetic fields that repels each other be away from two electric arcs be driven into slit, by slit to the cooling of electric arc and deionization, accelerate arc extinguishing.

Embodiment
Structure of the present utility model composition and connected mode is illustrated below in conjunction with accompanying drawing.
A kind of contact-making switch arc-control device, comprises two fixed contacts 1 and a moving contact 2, two fixed contacts 1 are connected on two nodes of circuit, by controlling the connection of two fixed contacts 1 or disconnecting the break-make of control circuit.Moving contact 2 is connected on driving mechanism, and this driving mechanism can be linkage or action bars, handle etc.Moving contact 2 can solve under driving mechanism drives or away from fixed contact 1, moving contact 2 can contact with two fixed contacts simultaneously, is coupled together by two fixed contacts, thus turning circuit.Two described fixed contacts 1 are symmetrical arranged, and are spaced from each other, and wear to keep can not being electrically shocked between the two.The contact of two fixed contacts is all towards moving contact, and moving contact is laterally crossed between two fixed contacts, and the two ends of moving contact are respectively equipped with the contact contacted with two fixed contacts.When producing electric arc between fixed contact and moving contact for two, two electric arcs parallel, and the sense of current is contrary, thus produce the magnetic field of repelling each other around two electric arcs.Two electric arc under the promotion in magnetic field of repelling each other rapidly away from, be convexly curved and be elongated, thus accelerating the extinguishing of electric arc.
In order to extinguish arcs faster, be respectively equipped with an insulation arc extinguishing board 3 in the both sides of two fixed contacts 1.This insulation arc extinguishing board can adopt the insulating material such as asbestos, cement, pottery to make.Insulation arc extinguishing board is provided with the slit 4 that the distribution arrangement along moving contact and fixed contact extends, and slit is all corresponding with the contact of moving contact and fixed contact.Distance between insulation arc extinguishing board 3 and fixed contact 1 should be less than the ultimate range that electric arc can depart under magnetic fields, thus electric arc is driven in slit.Described slit 4 is divided into entrance 401 and arc extinguishing section 402 two parts along its depth direction, and entrance is towards moving contact and fixed contact, and its width is greater than the diameter of the electric arc 5 formed between moving contact and fixed contact, is beneficial to electric arc and enters slit.The width of arc extinguishing section is less than the diameter of the electric arc formed between moving contact and fixed contact, to accelerate the extinguishing of electric arc in arc extinguishing section.
Described arc extinguishing section is divided into multiple space by the insulating barrier arranged along slit length direction, and each space communicates with entrance, and its extinguishing further can be accelerated in divided each space that enters of electric arc.
