Compared with prior art, the present invention can be switched between hand control and automation mutually, the rotating time can adopt the corresponding time relay arbitrarily to adjust according to actual needs, can adapt to the plant equipment of definite arbitrary motion form of forward and reverse time to the needs of Motor Control.Adopt the present invention to have following remarkable advantage:
(1) high efficiency can realize that hand switches mutually with automatic, and has manual interlock and manual crawl control function;
(2) under normal operating conditions, need not staff operation, when equipment needs interim rotating manually to control, can switch to manual control function and carry out the seat in the plane and accurately control;
(3) equipment operation cost of labor is low, easy to operate;
(4) can carry out accurately that forward, reversing time set, the time of forward and reverse can arbitrarily be regulated, and can switch at any time manual mode simultaneously in running automatically and manually control;
(5) the suitable device scope is very big, can satisfy the plant equipment of definite arbitrary motion form of forward and reverse time to the needs of Motor Control;
(6) by the one group of interlocking that utilizes separately main contactor self inside often open, normally closed main contacts is used for commutation, realize the rotating control of motor, because this main contactor internal lock is often opened, normally closed main contact can not be closed simultaneously, directly effectively prevent the short circuit of motor major loop, realized the control circuit interlock function.Motor forward/backward rotation is controlled the functional circuit part with manual crawl, manual linked control circuit part and is well defined with automatic control function circuit part function, the SB4 button is controlled the rotating of motor specially, the SB2 button is controlled the manual control model interlock of motor specially, the SB3 button is controlled the manual control model crawl of motor specially, and SB5(SA2) button is controlled manual, the automatic control mode switching of motor specially.Even the rotating button is pressed in misoperation under manual forward state, any circuit, electrical equipment accident can not occur yet, motor is only to become the counter-rotating running status by the forward running status; By automatic control mode forward (or counter-rotating) interlock state, SB5(SA2 is pressed in misoperation suddenly) the automatic control button startup of hand control automatically, motor moves immediately automatically, and any circuit, electrical equipment accident can not occur; Automatic control state knob down SB2, SB3, SB4 lose any control function to motor, therefore be no matter manually or any misoperation under auto state all can not cause the faults such as motor major loop and control circuit short circuit, this circuit has been stopped circuit, electrical equipment accident because misoperation causes from the circuit function structure.
The present invention utilizes the time-delay contact of 2 time relays or instantaneous contact to seal in respectively in non-time relay coil and phase reversal relay KM2 coil power supply circuit, realize rotating control running time interlocking in rotating time relay control circuit, realize simultaneously the control of rotating function control phase reversal relay KM2, thereby realize that motor forward/backward rotation controls automatically, and rotating can be regulated arbitrarily running time.By utilize several button, hand push button and manual compound buttons with low cost just realized in the circuit by connection in series-parallel manual/automatic integrated control and the function that can mutually switch, manually and the function of self interlocking, under the auto-controll operation state the fault-operation protection function, realized the interlock function of rotating under rotating interlock function and the automatic running status of hand in conjunction with the contact of relay.In the control circuit of relay K M1 main contact KM1-2, the KM1-3 normally open contact had both played the effect that the locking circuit is connected the control circuit power channel, had also played the decompression under-voltage protection effect of circuit simultaneously.Maximum innovative point is exactly: with relay K M1 coil and KM1-3 normally open contact, start button SB2, the control circuit that starts the main contact KM1-2 that compound button SB3 forms is an independent functional module, its function is mainly the startup of controlling the closed of main contact KM1-2 and controlling motor; The control circuit of button, relay K M2 and two time relay compositions is functional modules, special control the motor main line manually, the commutation under automatic control mode, be the rotating function, and realize the control of rotating time, interlock function under the auto-controll operation state.
The present invention can satisfy the plant equipment of definite arbitrary motion form of forward and reverse time to the needs of Motor Control, and the hand control and automation one also can be switched mutually, both can realize automatically, can realize again manual interlock, crawl control.Circuit structure is simple, and is easy to operate, low cost of manufacture.
