Description
Technical Field
The utility model relates to a isolator, concretely relates to isolator's arc extinguishing system.
Background
The isolating switch is used for infrequent connection and disconnection of circuits and electrical isolation in power distribution equipment of industrial and enterprise, and is widely applied to power distribution systems and automation systems in building, electric power, petrochemical industry and other industries. Isolator includes base, apron, handle, operating device, contact system, the arc extinguishing system of setting in the base, and current isolator's arc extinguishing system's structural design is unreasonable to this arc extinguishing system's arc extinguishing effect is relatively poor, and this isolator's arc extinguishing system still has the defect that the structure is complicated, the performance is unreliable, the assembly is not convenient.
Disclosure of Invention
An object of the utility model is to overcome prior art's defect, provide a simple structure, stable performance is reliable, the assembly is convenient, the effectual isolator's of arc extinguishing system.
For realize above-mentioned mesh, the utility model discloses an isolator's arc extinguishing system, including base, rotation setting contact frame in the base, with contact frame linkage complex moving contact, the both ends punishment that corresponds the moving contact do not set up two static contacts in the base, correspond two static contacts and the moving contact between the department set up two sets of arc extinguishing subassemblies in the base respectively, the arc extinguishing subassembly including corresponding between moving contact and the static contact locate to set up the explosion chamber in the base, correspond the below department of static contact and set up the first magnet on the contact frame, one side of explosion chamber on have the arc extinguishing passageway of shroud on the motion trail of moving contact, the contact frame on correspond arc extinguishing passageway department and be provided with second magnet.
The beneficial effect of above-mentioned structure is: arc extinguishing channel shroud of explosion chamber is on the movement track of moving contact to electric arc can enter into the explosion chamber fast, thereby can realize extinguishing fast of electric arc, and first magnet, second magnet can play the magnetism and blow the effect, are favorable to the cooling of electric arc, and first magnet, second magnet can blow electric arc into in the explosion chamber, thereby can realize extinguishing fast of electric arc. Therefore, the arc extinguishing system of the isolating switch has the advantages of simple structure, stable and reliable performance, convenience and quickness in assembly and good arc extinguishing effect.
Particularly, a clamping groove is formed in the position, corresponding to the second magnet, of the contact frame, a plurality of limiting convex strips are arranged in the clamping groove, the second magnet is clamped in the clamping groove, and the limiting convex strips are abutted to the second magnet respectively. The second magnet and the contact frame are assembled in a clamping fit mode, so that the second magnet and the contact frame are assembled conveniently, and the assembly efficiency of an arc extinguishing system of the isolating switch is improved.
Particularly, the base on correspond explosion chamber department and be provided with the draw-in groove, the explosion chamber block in the draw-in groove, and constitute the joint cooperation of explosion chamber and base. The arc extinguish chamber and the base are assembled in a clamping matching mode, so that the arc extinguish chamber and the base are convenient to assemble, and the assembly is more convenient.

Detailed Description
As shown in fig. 1-3, an embodiment of the present invention is an arc extinguishing system of isolating switch, including base 10, rotate the contact frame 11 that sets up in base 10, with contact frame 11 linkage complex moving contact 12, correspond two static contacts 13 that the both ends punishment of moving contact 12 set up respectively in base 10, correspond two sets of arc extinguishing components 20 that department set up respectively in base 10 between two static contacts 13 and the moving contact 12, arc extinguishing component 20 including corresponding moving contact 12 and static contact 13 between the explosion chamber 21 that department set up in base 10, correspond the below department of static contact 13 and set up first magnet 22 on contact frame 11, one side of explosion chamber 21 on have arc extinguishing channel 211 of shroud on the motion trail of moving contact 12, contact frame 11 on correspond arc extinguishing channel 211 department and be provided with second magnet 23. The contact holder 11 is provided with a clamping groove 111 corresponding to the second magnet 23, the clamping groove 111 is provided with a plurality of limiting convex strips 112, the second magnet 23 is clamped in the clamping groove 111, and the plurality of limiting convex strips 112 respectively abut against the second magnet 23. The second magnet and the contact frame are assembled in a clamping fit mode, so that the second magnet and the contact frame are assembled conveniently, and the assembly efficiency of an arc extinguishing system of the isolating switch is improved. The base 10 on correspond explosion chamber 21 department and be provided with draw-in groove 101, explosion chamber 21 block in draw-in groove 101, and constitute the joint cooperation of explosion chamber 21 and base 10. The arc extinguish chamber and the base are assembled in a clamping matching mode, so that the arc extinguish chamber and the base are convenient to assemble, and the assembly is more convenient.
Arc extinguishing channel shroud of explosion chamber is on the movement track of moving contact to electric arc can enter into the explosion chamber fast, thereby can realize extinguishing fast of electric arc, and first magnet, second magnet can play the magnetism and blow the effect, are favorable to the cooling of electric arc, and first magnet, second magnet can blow electric arc into in the explosion chamber, thereby can realize extinguishing fast of electric arc. Therefore, the arc extinguishing system of the isolating switch has the advantages of simple structure, stable and reliable performance, convenience and quickness in assembly and good arc extinguishing effect.
