Background technique
Breaker is the common control of one kind and protection equipment of power transmission and distribution industry, most important controller in electric system
Part, and the most frequent equipment of movement, when major function, control and subordinate's equipment are protected not to be burned.Work as grid collapses
When, breaker can fast reaction processing, avoid injuring, and breaker has higher failure rate in the process of running, once
Breaker, which breaks down, to be easy to cause power grid accident and results in significant economic losses, and therefore, the mechanical property of breaker is joined
Number must assure that within normal parameter area, if parameter is improper, in the event of a failure breaker if there is close not
The upper or point situation that do not fall, will cause serious consequence.Breaker mechanic property examination has become manufacturer and subscriber checking
One of the important indicator of breaker performance quality.
As long as one is by angular displacement sensor currently, the testing mechanical characteristic of VSI breaker is there are two types of mode in industry
It is mounted on main shaft, main shaft is mounted in circuit breaker frame (main element that frame is used to assemble breaker), is passed with angular displacement
Sensor measures mechanical property；Another kind is the insulated pull rod lower end that linear displacement transducer is mounted on to circuit breaker frame bottom.
Both measurement methods have certain problems: first is that angular displacement sensor higher cost, installation is inconvenient, straight-line displacement sensing
Device is mounted on circuit breaker frame bottom, when the lower end of insulated pull rod is not provided with wire hole, needs in addition to do a tooling to pacify
Linear displacement transducer is filled, it is very inconvenient；Second is that when testing, many producers are all handcart-type installations, the mechanical longevity is being done
When life test, primary characteristic need to be tested by often doing 2000 times, and chassis vehicle is just needed to dismantle at this time, mechanical characteristic test to be finished
It reinstalls top bottom-disc vehicle again afterwards and carries out running-in test, operate comparatively laborious.
To solve the above-mentioned problems, proposing notification number is " CN202066668U ", and entitled " vacuum circuit breaker is mechanical special
Property detection device " Chinese utility model patent file, the displacement sensor of the detection device and connector sleeve be connected, and when test is disconnected
Road device moving contact moves up and down, and connector sleeve is easy to appear axial movement, to drive the sliding bar of displacement sensor to deflect, easily
It causes linear displacement transducer to damage, and also results in breaker mechanic property examination result inaccuracy.In order to solve to be displaced
The problem of sliding bar deflection of sensor, proposing notification number is " CN204556241U ", a kind of entitled " high pressure vacuum open circuit
The Chinese utility model patent file of device mechanical characteristic testing device ", the company which will be fixedly connected with moving contact of breaker
It connects frame to protrude horizontally up, then is connect with linear displacement transducer sliding bar, not only structure is complicated, and easily forms " lever " phenomenon, makes
The displacement sensor that is in line damage, and cause breaker mechanic property examination result inaccurate.
