Description
Technical field
A kind of switch contact is the utility model is related to, more particularly to a kind of switch resistance arcing contact device.
Background technology
Existing common on-load switch drop-out current arc time in air, nitrogen is grown, and electric arc yield is big, using blowing
The mode of gas or magnetic blow-out formula cooling partition electric arc, since the arc time is grown, contact burning is fast, the short reliability of product service life
It is low.Security when in this case, to extend the service life of contact and ensureing on/off switch switch is, it is necessary to cut-off big electricity
Stream, although when so protecting contact breaking and making will not melting welding, be easy to cause and cut-off that arcing is long to cause failure of interruption
Phenomena such as, and the amount of labour of operator is increased to a certain extent, complicated, the problems such as efficiency is low.
Utility model content
Technical problem to be solved in the utility model be overcome the deficiencies of the prior art and provide it is a kind of it is simple in structure,
The switch resistance arcing contact device of easy to operate, safe to use and service life length.
Technical solution is used by the utility model：The utility model includes the static contact and moving contact to cooperate,
The static contact includes main contact, flow plug and connection auxiliary contact, the flow plug and is arranged at the main contact and the company
Between connecing auxiliary contact, the afterbody of the connection auxiliary contact is stretched out to the direction of the moving contact；The moving contact is to described
When static contact closes, the connection auxiliary contact is first touched, then touches the main contact again.
Further, the main contact is flat vertical contact block, and the main contact is equipped with mutual with the flow plug
The connecting hole of cooperation.
Further, the connection auxiliary contact 4 include the Horizontal Cylinder feeler lever one that is connected with the flow plug 3 and with
The tilted cylindrical envelope body feeler lever two that the Horizontal Cylinder feeler lever one is connected, the afterbody of the tilted cylindrical envelope body feeler lever two are located at institute
State on the track of movement radian of 1 contact of moving contact.
Further, the upper end of the flow plug is connected with the connecting hole of the main contact, the lower end of the flow plug and institute
Feeler lever one is stated to connect.
Further, the switch resistance arcing contact device further includes the quiet bearing of switch, and the lower end of the moving contact is opened with described
Close quiet bearing rotation connection.
The beneficial effects of the utility model are：Since the utility model includes the static contact and moving contact of mutual cooperation, institute
Stating static contact includes main contact, flow plug and connects auxiliary contact, and the flow plug is arranged at the main contact and the connection
Between auxiliary contact, so, the utility model is not only simple in structure, and because of the setting of flow plug, is switched in divide-shut brake process
In need not cut-off high current so that when protecting contact breaking and making will not melting welding, cut-off that arcing is long to cause failure of interruption
Phenomena such as, extend service life and ensure that safety in utilization.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the utility model；
Fig. 2 is the structure diagram of the static contact.
Embodiment
As depicted in figs. 1 and 2, the utility model includes the static contact and moving contact 1 to cooperate, and the static contact includes
Main contact 2, flow plug 3 and connection auxiliary contact 4, the flow plug 3 are arranged at the main contact 2 and the connection auxiliary contact
Between 4, the afterbody of the connection auxiliary contact 4 is stretched out to the direction of the moving contact 1；The moving contact 1 is to the static contact
During closure, the connection auxiliary contact 4 is first touched, then touches the main contact 2 again.
In the present embodiment, the main contact 2 is flat vertical contact block, and the main contact 2 is equipped with and the resistance
Flow the connecting hole that device 3 cooperates.
In the present embodiment, the connection auxiliary contact 4 includes the Horizontal Cylinder feeler lever being connected with the flow plug 3
One and the tilted cylindrical envelope body feeler lever two that is connected with the Horizontal Cylinder feeler lever one, the afterbody of the tilted cylindrical envelope body feeler lever two
It is such to ensure that the moving contact 1 be with most when closure on the track of the movement radian of 1 contact of moving contact
Fast speed is contacted with the tilted cylindrical envelope body feeler lever two.
In the present embodiment, the upper end of the flow plug 3 is connected with the connecting hole of the main contact 2, the flow plug 3
Lower end is connected with the feeler lever one.
In the present embodiment, the switch resistance arcing contact device further includes the quiet bearing 5 of switch, the lower end of the moving contact 1
It is rotatablely connected with the quiet bearing 5 of switch.
Utility model works principle：Running current and short circuit current flow through main contact by flowing through, separating brake process electric current
Flow plug is transferred to by main contact, auxiliary contact is gone to through flow plug.Making process switch movable contact first contacts auxiliary contact, after
Through flow plug to main contact.Because of the setting of flow plug, high current need not be cut-off during divide-shut brake by switching, so as to protect
During contact breaking and making will not melting welding, cut-off arcing long phenomena such as causing failure of interruption.
The utility model is applied to the technical field of medium-voltage equipment switch.
Although the embodiment of the utility model is described with practical solution, do not form the utility model is contained
The limitation of justice, for those skilled in the art, according to modification of this specification to its embodiment and the group with other schemes
Conjunction will be apparent from.
