A kind of vacuum circuit-breaker with life-span management function
Technical field
The utility model belongs to field of circuit breakers, is specifically related to a kind of vacuum circuit-breaker with life-span management function.
Background technology
Vacuum circuit-breaker is widely used in railway locomotive, motor train unit.Vacuum circuit-breaker has been born high-tension connection and breaking function between contact line and locomotive or motor train unit.Can vacuum circuit-breaker work and directly determine that can whole locomotive or motor train unit normally move.At present, there is larger difference in the frequency of utilization of vacuum circuit-breaker on different regions, different model locomotive, but the unified milimeter number according to locomotive operation of locomotive depot or determine service life locomotive supplementally take, in repair and plan of major repair.When locomotive medium-term repair, overhaul, the actual act number of times of vacuum circuit-breaker differs very greatly and is but keeped in repair by unified requirement, thereby can't accomplish not only reliably but also economical and effective the maintenance of vacuum circuit-breaker.If can not keep in repair and will bring great hidden danger to the safe operation of locomotive the vacuum circuit-breaker needed repairing in time, even cause machine to break or accident; But maintenance free vacuum circuit-breaker is carried out to a large amount of unnecessary maintenance work meetings locomotive depot is caused to the great wasting of resources.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, provides a kind of and can improve the reliability of vacuum circuit-breaker and whole electrical system the vacuum circuit-breaker with life-span management function that can rationally use.
For achieving the above object, the technical solution adopted in the utility model is: comprise vacuum circuit-breaker and mounting panel, be installed with counter and folding according to vacuum circuit-breaker on mounting panel and provide the auxiliary contact of signal for counter; Be provided with the actuating strut be connected with contact and the signal output part be connected with counter on auxiliary contact, actuating strut matches with vacuum circuit-breaker, on/off switch by vacuum circuit-breaker drives actuating strut, make auxiliary contact produce the signal of telecommunication, the signal output part on auxiliary contact is counted electrical signal transfer to counter.
Above-mentioned counter be can not zero clearing counter.
Compared with prior art, the utlity model has following beneficial effect:
The utility model has added counter on vacuum circuit-breaker, constantly record the actual act number of times of vacuum circuit-breaker by counter, vacuum circuit-breaker is carried out to the service life supervision management, make use and the maintenance of vacuum circuit-breaker have more specific aim with scientific, can carry out scientific and effective inspection and maintenance according to the actual act number of times of the disconnected device of vacuum when maintenance, use with scientific maintenance foundation is provided for the locomotive electric apparatus reliability, for using, motorcycle safety provides the science guarantee, thereby overcome the unnecessary maintenance of locomotive that prior art causes and or the wasting of resources, improved the reliability and availability of vacuum circuit-breaker and whole locomotive electric cad system system, unnecessary manpower and material resources waste have been reduced simultaneously.
The accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is upward view of the present utility model.
Wherein, 1 is vacuum circuit-breaker; 2 is counter; 3 is auxiliary contact.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Referring to 1 figure, the utility model comprises vacuum circuit-breaker 1 and mounting panel, on mounting panel, be installed with one can not zero clearing counter 2 and folding according to vacuum circuit-breaker 1 provide the auxiliary contact 3 of signal for counter 2; Be provided with the actuating strut be connected with contact and the signal output part be connected with counter 2 on auxiliary contact 3, actuating strut matches with vacuum circuit-breaker 1, on/off switch by vacuum circuit-breaker 1 drives actuating strut, make auxiliary contact 3 produce the signal of telecommunication, the signal output part on auxiliary contact 3 is counted electrical signal transfer to counter 2.
The utility model is after the 1 energising adhesive of vacuum circuit breaker, and auxiliary contact 3 provides count signal one time for counter 2, and once, counter 2 is just recorded the actual act number of times of vacuum circuit-breaker 1 in counter 2 numerations.The action frequency of the vacuum circuit-breaker 1 that records number of times and manufacturer and provide of counter 2 respectively being repaiied to journey is contrasted, thereby vacuum circuit-breaker 1 is formulated to scientific and effective maintenance program.
Application of the present utility model makes the use of vacuum circuit-breaker and maintenance have more specific aim with scientific, for the locomotive electric cad system system is reliable, uses with scientific maintenance foundation is provided, and for motorcycle safety uses, provides the science guarantee, has reduced the unnecessary wasting of resources simultaneously.
