Load motor frequent starting and stopping, the service life for reducing the rush of current to load motor, increasing motor.
Detailed description of the invention
Fig. 1 is the secondary control circuit structure of the no-harass switch of the utility model.
In figure:
1:SA1 change-over switch, 2: remotely start contact, 3:SB1 local boot button,
4:KM1 contactor coil, the local 5:SB2 stop button, 6: remotely stop contact, 7:KM1 contactor auxiliary contact.
Specific embodiment
Specific embodiment of the present utility model is described further with reference to the accompanying drawing.It should be noted that
The explanation of these embodiments is used to help to understand the utility model, but does not constitute the restriction to the utility model.This
Outside, technical characteristic involved in the various embodiments of the present invention described below is as long as they do not conflict with each other
It can be combined with each other.
As shown in Figure 1, the utility model discloses the secondary control circuit structure of no-harass switch, including SA1 change-over switch
1, remotely start contact 2, SB1 local boot button 3, KM1 contactor coil 4, the local SB2 stop button 5, remotely stop contact
6, KM1 contactor auxiliary contact 7, the SA1 change-over switch 1 have local and long-range two kinds of working conditions, and the SA1 conversion is opened
Remote status station, the long-range starting contact 2 and the KM1 contactor coil 4 for closing 1 are composed in series long-range control loop,
The local state station of the SA1 change-over switch 1, the local SB2 stop button 3 connect after with the SA1 change-over switch 1
The branch that remote status station, the long-range starting contact 2 are composed in series carries out in parallel, the local SB2 stop button 5, institute
State it is long-range stop after contact 6, the KM1 contactor auxiliary contact 7 series connection with the remote status station of the SA1 change-over switch 1,
The branch that the long-range starting contact 2 is composed in series carries out composing in parallel circuit.
When the SA1 change-over switch 1 is in local state of a control, SB1 local boot button 3 is pressed, KM1 contactor coil
4 power on, and KM1 contactor auxiliary contact 7 power on also with KM1 contactor coil 4 and are closed and then constitute self-locking circuit at this time, make
KM1 contactor coil 4 SB1 local boot button 3 reset after still persistently it is electric, then KM1 contactor coil 4 main contacts suction
It closes, primary main current supply circuit is connected, load motor operation, when the SA1 change-over switch 1 is switched to by local state of a control at this time
When long-range state of a control, due to the local SB2 stop button 5, long-range stopping contact 6, KM1 contactor auxiliary contact 7, KM1
Contactor coil 4 still constitutes self-locking circuit, and load motor still maintains the state of local state of a control load motor operation before switching.
After the completion of switching state, the long-range stopping contact 6 is acted, and normally off becomes open state, and load motor is out of service；Work as institute
When stating SA1 change-over switch 1 and switching to local state of a control by long-range state of a control, action process is identical.
The secondary control circuit structure of the no-harass switch of the utility model, by providing under local and remote controlled manner
It is able to achieve the secondary control loop of no-harass switch, converts control authority mutually in local state of a control and long-range state of a control
When, load state of a control can be kept to convert before state to realizing switching undisturbed, make to operate more convenient, avoid simultaneously
Load motor frequent starting and stopping, the service life for reducing the rush of current to load motor, increasing motor.
