Abstract
The invention discloses a closing speed reduction based method for improving the processing efficiency of closing bounce, comprising a circuit breaker. A closing spring and an opening spring are arranged on the circuit breaker; and the circuit breaker is a low-oil circuit breaker, the length of the closing spring on the circuit breaker is 128mm, and the length of the opening spring is 970mm. By regulating the length of the closing spring, the invention can regulate the power of the closing spring, reduce the end voltage of a closing coil, regulate the prestretching strength of the opening spring so as to reach the aim of improving the processing efficiency of the closing bounce, shorten the time for eliminating the closing bounce and decrease the closing bounce frequency through maintenance and overhauling.
Description
Technical field
The present invention relates to circuit breaker, relate in particular to a kind of based on reducing the method that closing speed improves processing closing rebound efficient.
Technical background
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 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 improve the method for handling closing rebound efficient based on the reduction closing speed, it reaches the purpose that improves processing closing rebound efficient by reducing closing speed.
The technical scheme that realizes above-mentioned purpose is: a kind of based on reducing the method that closing speed improves processing closing rebound efficient, comprise circuit breaker, have switching-in spring and tripping spring on the vacuum circuit-breaker, wherein, described circuit breaker is an oil-minimum breaker, the length of the switching-in spring on this circuit breaker is set to 128mm, and the length of tripping spring is set to 970mm.
Above-mentioned improve the method for handling closing rebound efficient based on reducing closing speed, wherein, also include closing coil, the terminal voltage by reducing closing coil is to reduce closing speed.
Above-mentioned improves the method for handling closing rebound efficient based on reducing closing speed, wherein, comprises that also the pre-stretching length of adjusting tripping spring is to reduce opening velocity.
The invention has the beneficial effects as follows: the present invention adjusts the strength of switching-in spring, the terminal voltage that reduces closing coil, adjustment tripping spring by the length of adjusting switching-in spring pre-stretching length improves the purpose of handling closing rebound efficient to reach, it can reduce the time of getting rid of closing rebound, by Maintenance and Repair, reduce the number of times of closing rebound.
Embodiment
Below with the invention will be further described.
Of the present invention a kind of based on reducing the method that closing speed improves processing closing rebound efficient, comprise circuit breaker, have switching-in spring, tripping spring, closing coil on the vacuum circuit-breaker, circuit breaker is an oil-minimum breaker, model is SW2-35, the length of the switching-in spring on this circuit breaker is set to 128mm, and the length of tripping spring is set to 970mm.
The present invention adjusts the length of switching-in spring to realize reducing the purpose of closing speed with the strength of adjusting switching-in spring, and terminal voltage that can also be by reducing closing coil and the pre-stretching length of adjusting tripping spring are to reduce opening velocity.
By above-mentioned scheme, can reach the effect that reduces closing speed, improve the purpose of handling closing rebound efficient.
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.
