Specific embodiment
In order to make the purpose of the utility model, technical solutions and advantages more clearly understood, below in conjunction with attached drawing and implementation
Example, the present invention will be further described in detail.It should be appreciated that specific embodiment described herein is only to explain this
Utility model is not used to limit the utility model.
With reference to Fig. 1 and Fig. 2, as depicted in figs. 1 and 2, a kind of anti-shake electric circuit, including frequency converter connection circuit and secondary returning
Road;It is that anti-shake base site controller passes through instant contact relay KA1 connection frequency converter that frequency converter, which connects circuit,;The secondary circuit packet
Include circuit breaker Q F4, first switch YX, second switch GZ, the first relay KV1, the second relay KV3, first time relay
KT1, the second time relay KT2;Circuit breaker Q F4 is separately connected first switch YX and second switch GZ;First switch YX difference
Connect the first relay KV1, first time relay KT1;Second switch GZ is separately connected the second relay KV3, the second time
Relay KT2.
The circuit breaker Q F4 voltage rating is 230/400V, model DZ47-C10,1P.
The first relay KV1, the second relay KV3 are the relay of AC220/240V.First relay KV1 type
Number be MY4NJ, the second relay KV3 model MY2NJ.
The first time relay KT1 is the power cut off delay time relay, delay time 60s, specified control electricity
Source voltage is AC220V;Second time relay KT2 is the on-delay time relay, delay time 1s/10s/
60s/60min, specified control supply voltage are AC220V.
First time relay KT1 model JSZ3F.
Second time relay KT2 model JSZ3.
TPM-Q is anti-shake electric controller.
(YX- is run, GZ- event by the signal output control of frequency converter internal relay by first switch YX, second switch GZ
Barrier);When frequency converter is started to work, YX is closed.When frequency converter is faulty, GZ is closed.
The circuit of the utility model, opens the feeder ear that Q terminal connects frequency converter starting relay, and L1, L2, L3 connect power supply electricity
