Abstract
The invention discloses a method for improving switching-on tripped processing efficiency based on changing an excessive stroke. A circuit breaker is comprised, wherein a contact end is arranged on the circuit breaker; when the circuit breaker is a low-oil content circuit breaker, the opening distance of the contact end, namely total stroke ranges from 142mm to 149mm or 305mm to 320mm; and when the circuit breaker is a vacuum circuit breaker, the opening distance of the contact end ranges from 7.5mm to 8.5mm or 9mm to 12.5mm. The method for improving switching-on tripped processing efficiency based on changing the excessive stroke is used for changing the excessive stroke by adjusting the opening distance of the contact end of the circuit breaker to achieve the aim of improving the switching-on tripped processing efficiency.
Description
Technical field
The present invention relates to circuit breaker, relate in particular to a kind of based on changing the method that excess of stroke size 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 change excess of stroke size, it changes excess of stroke size to reach the purpose that improves processing closing rebound efficient by the distance of opening of adjusting contact of breaker.
The technical scheme that realizes above-mentioned purpose is:
The a kind of of one of the present invention improves the method for handling closing rebound efficient based on changing excess of stroke size, comprise circuit breaker, have contact on the circuit breaker, wherein, when described circuit breaker is oil-minimum breaker, the opening apart from being that the scope of total kilometres is 142mm～149mm or 305mm～320mm of its contact.
Above-mentioned improves the method for handling closing rebound efficient based on changing excess of stroke size, and wherein, the distance of opening of described contact is 145mm.
Above-mentioned improves the method for handling closing rebound efficient based on changing excess of stroke size, and wherein, the distance of opening of described contact is 310mm.
The present invention two a kind ofly improve the method for handling closing rebound efficient based on changing excess of stroke size, comprise circuit breaker, have contact on the circuit breaker, wherein, when described circuit breaker was vacuum circuit-breaker, the scope of opening distance of its contact was 7.5mm～8.5mm or 9mm～12.5mm.
The invention has the beneficial effects as follows: the method for handling closing rebound efficient that improves based on change excess of stroke size of the present invention changes excess of stroke size to reach the purpose that improves processing closing rebound efficient by the distance of opening of adjusting contact of breaker, 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.

The present invention two a kind ofly improve the method for handling closing rebound efficient based on changing excess of stroke size, comprise circuit breaker, has contact on the circuit breaker, when circuit breaker is vacuum circuit-breaker, the scope of opening distance of its contact is 7.5mm～8.5mm or 9mm～12.5mm, its scope of the vacuum circuit-breaker of different model is also different, as shown in the table:
| The vacuum circuit-breaker model | Open apart from scope | Excess of stroke scope |
| ??VB5 | ??11-12.5mm | ??2-4mm |
| ??ZN21-12 | ??9-11mm | ??2-4mm |
| ??ZN21-10 | ??9-10mm | ??2-3mm |
| ??ZN18-10 | ??7.5-8.5mm | ??2.5-3.5mm |
| ??ZN28-10 | ??10-12mm | ??3-5mm |
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.
