On machine input terminal, to realize the positive and negative rotation of power supply.
The application method and working principle of the utility model are:
1, working principle:
(1) working principle when local operation:
Such as attached drawing 2, firstly, I9 input terminal does not have external block signal to open by the control power supply and motor of disconnecting switch
Power supply, which is spaced apart, closes (I19 input terminal is that high level is effective), plugs five anti-lock (I22 input terminal is that high level is effective), will be isolated
Handle switches to (I1 input terminal is that low level is effective) on the spot on the spot in a switch distant place, and separate selection handle is then switched to oneself
Certain of desired operation is isolated on switch, and when such as operating A case, handle is switched to A phase.Then switch knob (I6 input is pressed
End be high level it is effective), at this point, the OUT1 output end of single-chip microcontroller be high level, start KMA1 relay, A phase motor operation into
And close A and isolate switch, stop when disconnecting switch closes (I10 input terminal is that high level is effective) completely.Separating brake and
It is all same principle that other two-phases or three-phase operate simultaneously.
(2) working principle when remote operation:
Such as attached drawing 3, firstly, I9 input terminal does not have external block signal to open by the control power supply and motor of disconnecting switch
Power supply, which is spaced apart, closes (I19 input terminal is that high level is effective), by a disconnecting switch distant place, afield (I1 is inputted for handle switching on the spot
End is that high level is effective), since remote operation does not need individual-phase control, it is separate not need handle selection on the spot.Work as a distant place
When combined floodgate is opened into (I20 input terminal is that high level is effective), disconnecting switch three-phase instrument closes a floodgate or separating brake.
