Abstract
The utility model relates to a vacuum switch moving contact pressure spring device which is capable of effectively solving the problems that a contact spring of a vacuum switch is not easy to stall, the overtravel and the contact wear extent are difficult to measure. According to the technical scheme, the vacuum switch moving contact pressure spring device comprises a round steel pull rod, an insulating pull rod and a contact spring; the round steel pull rod is connected with the insulating pull rod; the round steel pull rod is provided with a long-strip-shaped hole penetrating through the round steel pull rod; a steel sleeve is installed on the round steel pull rod through a fixed pin sleeve horizontally inserted in the long-strip-shaped hole so as to enable the steel sleeve to slide left and right along the round steel pull rod; the inner side of the steel sleeve is provided with the contact spring, the contact spring sleeves the round steel pull rod, and one end of the contact spring is connected with the insulating pull rod; the outer side of the steel sleeve is provided with nuts, and the nuts are screwed to the round steel pull rod and are used for limiting. The vacuum switch moving contact pressure spring device is novel and unique in structure, simple and reasonable, easy to produce, low in cost and convenient to install; by adopting the vacuum switch moving contact, the overtravel and the contact wear extent can be directly measured by a straight ruler, the usage effect is good, and the social economic benefits are good.
Description
Technical field
The utility model relates to a kind of vacuum switch moving contact compression-spring device for vacuum switch in power switchgear.
Background technology
Vacuum switch (containing circuit breaker, on-load switch, contactor etc.) needs the contact that keeps certain in the time of "on" position between its moving contact and fixed contact, this realizes by touch spring.At present, the conventional mounting means of touch spring has two kinds:
1, by roller (or bearing) compression contacts spring, touch spring is exerted pressure to the moving contact of vacuum interrupter by insulated tension pole, and its shortcoming is to be difficult for installing, and overtravel is not directly perceived;
2, touch spring (helical compression spring or disk spring) is arranged on insulated tension pole inside, although be convenient to like this install, can not directly measure overtravel, can not measure the contact head abrasive loss of switch.
Therefore, its improvement and bring new ideas is imperative.
Summary of the invention
For above-mentioned situation, for overcoming the defect of prior art, the object of the utility model is just to provide a kind of vacuum switch moving contact compression-spring device, can effectively solve the touch spring of vacuum switch, is difficult for installing, and overtravel and contact head abrasive loss are difficult to the problem of measuring.
The technical scheme that the utility model solves is, comprise round steel pull bar, insulated tension pole and touch spring, round steel pull bar and insulated tension pole link together, the strip hole connecting before and after having on round steel pull bar, the steady pin of steel bushing in level is inserted into strip hole is sleeved on round steel pull bar, form steel bushing along the left and right slide construction of round steel pull bar, the inner side of steel bushing is set with the touch spring that one end is connected with insulated tension pole on round steel pull bar, and the outside of steel bushing is installed with for spacing nut on round steel pull bar.
The utility model novel structure uniqueness, advantages of simple, easily produces, and cost is low, easy for installation, can directly measure overtravel and contact head abrasive loss with ruler, and result of use is good, has good society and economic benefit.
Accompanying drawing explanation
Fig. 1 is use state diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.
Provided by Fig. 1, the utility model comprises round steel pull bar, insulated tension pole and touch spring, round steel pull bar 1 links together with insulated tension pole 6, the strip hole 7 connecting before and after having on round steel pull bar 1, the steady pin 3 of steel bushing 4 in level is inserted into strip hole 7 is sleeved on round steel pull bar 1, form steel bushing along the left and right slide construction of round steel pull bar, the inner side of steel bushing 4 is set with the touch spring 5 that one end is connected with insulated tension pole 6 on round steel pull bar, and the outside of steel bushing 4 is installed with for spacing nut 2 on round steel pull bar.
In order to guarantee result of use, described nut 2 has side by side 2;
The diameter of described round steel pull bar 1 is less than the diameter of insulated tension pole 6;
Described nut 2, steel bushing 4, touch spring 5 and insulated tension pole 6 be end to end touching successively;
Described touch spring 5 can be helical spring or butterfly spring.
Service condition of the present utility model is, while carrying out closing operation, external force pulls steel bushing 4 to move, under the effect of thrust, drive round steel pull bar 1 and insulated tension pole 6 to move, the stroke of round steel pull bar 1 is switch contact stroke, while there is overtravel, steady pin 3 moves along strip hole 7 under the effect of pressure, thereby drive steel bushing 4 compression contacts springs 5, now, gap between nut 2 and steel bushing 4 is overtravel, therefore, can directly measure overtravel and contact head abrasive loss with ruler, compared with prior art, the utility model novel structure uniqueness, advantages of simple, easily produce, cost is low, easy for installation, can directly measure overtravel and contact head abrasive loss with ruler, result of use is good, promotion prospect is large, there are good society and economic benefit.
