A kind of electromagnetic contactor of tape counter
Technical field
The utility model relates to a kind of electromagnetic contactor, is specifically related to a kind of electromagnetic contactor of tape counter.
Background technology
The QCC1 electromagnetic contactor is applicable to the contactor that uses in railway electric locomotive, diesel locomotive, electric motor car group and the industrial automation control appliance.At present, because the difference of each locomotive means of transportation, so caused the frequency of utilization of similar contactor on different locomotives to have than big-difference, but each locomotive depot all be according to the milimeter number of locomotive operation determine locomotive supplementally take, in repair with overhaul, thereby cause part maintaining phase contactor in good condition is carried out unnecessary maintenance, but the contactor that needs place under repair is not obtained timely stage by stage maintenance, brought hidden danger for the safe operation of locomotive.
Summary of the invention
The purpose of this utility model is to overcome the shortcoming of above-mentioned prior art, and provide a kind of and can improve single contactor, and the electromagnetic contactor of the reliability of whole electrical system and the tape counter that can increase the service life.
For achieving the above object, the technical solution adopted in the utility model is: comprise electromagnetic contactor, on the auxiliary contact support of electromagnetic contactor and auxiliary contact a counter is installed side by side.
Because the utility model has been installed counter on contactor, write down the action frequency of contactor constantly by counter, contactor is carried out the service life supervision management, thereby it is broken to be to overcome locomotive that prior art causes unnecessary maintenance and machine, improved single contactor, and the reliability of whole electrical system.
Description of drawings
Fig. 1 is an overall structure schematic diagram of the present utility model;
Fig. 2 is the end view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing the utility model is described in further detail.
Referring to Fig. 1,2, the utility model comprises electromagnetic contactor, on the auxiliary contact support 2 of electromagnetic contactor and auxiliary contact 1 counter 4 is installed side by side.
The utility model has been installed counter 4 at the auxiliary contact support 2 of contactor side by side with auxiliary contact 1, when contactor coil 5 energisings make armature 6 adhesives, thereby driving cam 3 rotates, make auxiliary contact 1 action once, the Chang Kaiduan closure, effective call meter 4, just numeration is once, note the number of times of contactor action according to counter 4, thereby judge whether this contactor needs repairing.
It is long that the utility model does not have machinery wearing and tearing, life-span, with the auxiliary contact of contactor the normal use that does not influence contactor is installed side by side.
