Description
Technical field
It the utility model is related to a kind of excessive joint method of sensor, it is specifically a kind of for vacuum circuit breaker tachometric survey
The excessive joint of sensor, belongs to breaker technical field.
Background technology
The mechanical property of primary cut-out is to ensure the key of normal operation of circuit breaker.Therefore, primary cut-out machine is reacted
Tool characteristic parameter (switch closing and switch opening time, speed, open away from, the excess of stroke, three-phase asynchrony, bounce time etc.) be to judge that its is special
The important indicator of sign.Testing mechanical characteristic is measurement and the important means for ensureing breaker quality condition and performance indications.
《The primary cut-outs of GB1984-2003》Regulation, breaker type approval test, dispatch from the factory or commissioning test before, must test
The mechanical property parameter such as lost motion curve, record time, displacement, speed.In addition, breaker during the use that puts into operation, is used
Family also must be according to technical requirements and testing regulations《DL/T596-1996 power equipment preventive trial codes》, periodically carry out machinery
Characteristic test, to prevent or find circuit breaker failure and exception.
Moving contact rectilinear transducer method is generally used to the testing mechanical characteristic of breaker in the prior art.It is specific and
Speech, moving contact of breaker movable information is introduced into breaker mechanic property examination instrument by rectilinear transducer and measured：Stroke curve,
The parameters such as displacement (stroke, the excess of stroke), speed.Breaker straight-line transmitting lever is moved complete with moving contact divide-shut brake motion actual curve
Unanimously, the displacement-time curve measured really embodies multiple performance parameter and characteristic completely.In order to which convenient test is fast disconnected
Road device straight-line transmitting lever bottom is equipped with sensor connector connection complementary screw-threads silk hole, and made tested specially shelve it is disconnected
The testing jig of road device, it is convenient to install and use rectilinear transducer from bottom.
But before breaker matches somebody with somebody switch cubicle, manufacturer is mounted with to promote chassis vehicle in breaker, has blocked straight-line transmitting
Lever bottom.Complete testing mechanical characteristic is carried out, need to be removed and be promoted chassis vehicle and need to shelve the testing jig of breaker,
Rectilinear transducer can just be installed and used.And use at the scene, first without the special testing jig for shelving breaker, even if
Have, the breaker movement special equipment handling rectilinear transducer of no factory and test are one and cause high effort for time-consuming work
Make.Part producer, which considers user, need to carry out preventive trial this actual demand, be left in breaker main shaft termination special
Turn-sensitive device mounting hole.
In the case where loading and unloading rectilinear transducer difficulty, though there is some shortcomings part (such as using turn-sensitive device：Need to input
Travel parameters), but still a kind of effective measurement (stroke -- time) means of also can yet be regarded as.But when producing and processing main shaft, to ensure
Electroplating technique, the M6 that axle is suspended on production line during special power supply plating is left at crank of circuit breaker spindle end center and is arrived
The silk hole of the M12 sizes such as not, rotation sensing shaft coupling is docked with joint.However, factory completely do not consider user need to carry out it is pre-
Anti- property tests this actual demand.There is no the silk hole that can connect turn-sensitive device shaft coupling on axle, though portioned product is beaten in shaft end
There is centre bore, but there is no tapping.
Therefore, it is necessary to study new excessive joint, and can solve following problem：
1) crank of circuit breaker spindle centerline and sensor shaft coupling longitudinal center line must excessively be ensured after joint installation
Unanimously；
2) excessively joint is consistent with corner during crank of circuit breaker motion of main shaft after fixing, it is impossible to has and turns outside main shaft rotation
It is dynamic；
3) excessively joint axially should not have play after fixing, and solve the difficult point of this problem.
