Abstract

The invention discloses a method for improving switching-on tripped processing efficiency based on adjusting an insulating pull rod. A circuit breaker is comprised, wherein a contact end compression spring sealed in an insulating cylinder is contained on the circuit breaker; the contact end compression spring is a disc spring; and the pressure of the disc spring is adjusted to ensure the pressure of a contact end, namely excess stroke. The method for improving switching-on tripped processing efficiency achieves the aim of improving the switching-on tripped processing efficiency by adjusting the insulating pull rod, ensures that the contact end has larger contact pressure in an electric abrasion state to a certain extent, ensures the cushion of the moving contact end in the switching-on process and improves the just-open speed of the circuit breaker and the arc extinguishing performance.

Description

Handle the method for closing rebound efficient based on the raising of adjusting insulated tension pole
Technical field
The present invention relates to circuit breaker, relate in particular to a kind of method of handling closing rebound efficient based on the raising of adjusting insulated tension pole.
Technical background
Vacuum circuit-breaker because of its arc-extinguishing medium and arc extinguishing after the dielectric in contact gap all be that high vacuum is gained the name; It has volume little, in light weight, be applicable to the advantage that frequent operation, arc extinguishing need not overhaul, in power distribution network, use comparatively universal.
When the characteristic of vacuum circuit-breaker is tested, the phenomenon that discovery has some test datas to exceed standard, wherein, the closing rebound data account for the first place of the quantity that exceeds standard, and how improving processing closing rebound efficient is the problem that the present inventor is devoted to study.
Summary of the invention
The objective of the invention is to overcome the defective of prior art and provide a kind of and handle the method for closing rebound efficient based on the raising of adjusting insulated tension pole, it reaches and improves the purpose of handling closing rebound efficient by adjusting insulated tension pole.
The technical scheme that realizes above-mentioned purpose is: a kind of method of handling closing rebound efficient based on the raising of adjusting insulated tension pole, comprise circuit breaker, comprise the contact compressing spring that is sealed in the insulating cylinder on the circuit breaker, this contact compressing spring is the dish spring, wherein, the pressure of adjusting the dish spring is to guarantee the pressure of contact, the i.e. excess of stroke.
The above-mentioned method based on the raising processing closing rebound efficient of adjusting insulated tension pole, wherein, when described circuit breaker was vacuum circuit-breaker, the pressure of its contact was that the excess of stroke remains in the 2-5mm scope by regulating the dish spring.
The invention has the beneficial effects as follows: the method for handling closing rebound efficient based on the raising of adjusting insulated tension pole of the present invention guarantees under electrical wear state to a certain degree by adjusting dish spring pressure, guarantees that contact has bigger contact pressure; Guarantee the buffering in the switch on of moving contact process; Improve the just-off speed of circuit breaker, improve arc extinction performance.
Embodiment
Below with the invention will be further described.
A kind of method of handling closing rebound efficient based on the raising of adjusting insulated tension pole of the present invention, comprise circuit breaker, comprise the contact compressing spring that is sealed in the insulating cylinder on the circuit breaker, this contact compressing spring is the dish spring, the pressure of adjusting the dish spring is to guarantee the pressure of contact, the i.e. excess of stroke.
When circuit breaker was vacuum circuit-breaker, the pressure of its contact was that the excess of stroke remains in the 2-5mm scope by regulating the dish spring, and at the vacuum circuit-breaker of different model, its excess of stroke scope is also different, as shown below:
The vacuum circuit-breaker model Excess of stroke scope
??VB5 ??2-4mm
The vacuum circuit-breaker model Excess of stroke scope
??ZN21-12 ??2-4mm
??ZN21-10 ??2-3mm
??ZN18-10 ??2.5-3.5mm
??ZN28-10 ??3-5mm
The pressure that the present invention adjusts the dish spring is in order to guarantee the pressure of contact, i.e. compression (excess of stroke).And guarantee that compression is first is in order to guarantee under electrical wear state to a certain degree, to guarantee that contact has bigger contact pressure; The secondth, in order to guarantee the buffering in the switch on of moving contact process; The 3rd is the just-off speed that improves circuit breaker, improves arc extinction performance.
Below in conjunction with the embodiments the present invention is had been described in detail, those skilled in the art can make the many variations example to the present invention according to the above description.Thereby some details among the embodiment should not constitute limitation of the invention, and the scope that the present invention will define with appended claims is as protection scope of the present invention.
