Embodiment
Below in conjunction with attached drawing, the present invention is further illustrated.
By Fig. 1-4 as it can be seen that a kind of electromagnetic contactor of tape counter, including electromagnetic contactor 1, counter 4, counter drive
Moving part 5 and moving contact rack 2, the counter 4 is mechanical counter, and the electromagnetic contactor 1 includes shell, and electromagnetism connects
Tentaculum 1 is equipped with moving contact rack 2, and the counter 4 is equipped with counter actuator 5, the counter actuator 5
End is connected with moving contact rack 2, drives counter actuator 5 to move by moving contact rack 2, touches counter actuator 5
Hair counter 4 is counted；The counter 4 is connected by counter-support 3 with electromagnetic contactor 1.The electromagnetic touch
The shell of device 1 is equipped with two card slots 12, and the counter-support 3 is equipped with the buckle 31 agreed with 12 phase of card slot, passes through
The clamping of buckle 31 and card slot 12 so that counter-support 3 is fixed on the shell of electromagnetic contactor 1；The counter branch
Frame 3 is equipped with threaded hole 1, and the base of the counter 4 is equipped with threaded hole 2 41, by screw by threaded hole 1

Groove 1 on the shell of device 1, is arranged in the groove 2 21 on moving contact rack 2.2 flip-flop number of moving contact rack
During 4 counting, the stroke of moving contact rack 2 is more than the 1/2 of 2 total kilometres of moving contact rack.
When it is implemented, when electromagnetic contactor 1 is powered and is attracted, the upper surface of the groove 2 21 on moving contact rack 2 drives
Counter actuator 5 moves downward, and when counter actuator 5 is moved downwardly to designated position, counter 4 is counted once.
By appropriate design, can make moving contact rack 2 make when being moved downwardly to distance to a declared goal counter actuator 5 to
Under move to designated position, counter 4 is counted once.The distance ensure in attracting process dynamic/static contact apart from this apart from when
Electric arc will not be produced between contact.For example when the stroke of moving contact rack 2 is the 2/3 of 2 total kilometres of moving contact rack, make counting
Device 4 counts once.
When moving contact rack 2 continues down, distance reduces rapidly between dynamic/static contact, is likely to draw between dynamic/static contact
Arc, so even if making dynamic/static contact finally be not in contact with for some reason afterwards, being also considered as electromagnetic contactor had a sub-band
Electronic work and count once.
When moving contact rack 2 is moved downwardly to attracted position, if electromagnetic contactor causes to lead because of contact poor quality
It is very little due to there is the probability of three-phase while phase shortage, certain phase phase shortage, other several phases still contact during electric power loop phase shortage
, so counter should count at this time.If electromagnetic contactor causes virtual connection to be touched because of contact poor quality, due to continuing
Arcing is very big on contact influence, so counter should also count at this time.Since phase shortage and virtual connection triggering are raw in electromagnetic contactor
In the case of actuation, when moving contact rack 2 is moved downwardly to attracted position, counter 4 has counted once, thus phase shortage and
Counting in the case of virtual connection is touched will not omit.
When phenomena such as mechanical card resistance occurs in the executing agency of electromagnetic contactor 1, moving contact rack 2 is caused not move downward also
To distance to a declared goal when, that is, stop motion, electric arc will not be produced between dynamic/static contact at this time, so it is powered to be included in electromagnetic contactor 1
Action frequency.The upper surface of the groove 2 21 of moving contact rack 2 fails to drive counter actuator 5 to be moved downwardly to specific bit at this time
Put, so counter 4 is without counting.
Since the present invention can reasonably record the powered action frequency of electromagnetic contactor, by the powered of counter records
The electric life number for the electromagnetic contactor that action frequency is provided with manufacturer is contrasted, it is possible to judges electromagnetic contactor
Whether need repairing or replace, improve economy and security in electromagnetic contactor use.
