Specific embodiment

In order to be more clear goal of the invention of the invention, technical solution and its advantageous effects, below in conjunction with attached drawing And specific embodiment, the present invention will be described in further detail；

In the accompanying drawings: a kind of warship marine electric machine positive and negative rotation control system, it is characterised in that: including being connected to the motor the main circuit connect And the control circuit of component is controlled, one end three-phase windings U, V, W that motor 1 is accessed in the main circuit is provided with hot relay Device 2, one end of contactor a contact 3 and power input L1, L2, L3 are connected, and the other end and output end U2, V2, W2 are connected, and connect Tentaculum b contact 4 is set as in parallel with contactor a contact 3；The control circuit includes motor forward direction running control circuit, electricity Machine inverted running control circuit, positive running control circuit are set as in parallel with inverted running control circuit, forward direction operation control Electrothermal relay contact 2-1 and button contacts a5, button contacts b6, contactor b contact 4, contactor a coil 7 are carried out in circuit Series connection, contactor a contact 3 is in parallel with button contacts b6, and it is in parallel with contactor a coil 7 to rotate forward indicator light 11；Inverted running control Electrothermal relay contact 2-1 and button contacts a5, button contacts c8, contactor a contact 3, contactor b coil 9 are carried out in circuit Series connection, contactor b contact 4 is in parallel with button contacts c8, and reversion indicator light 10 is in parallel with contactor b coil 9.

Power supply power supply in the main circuit control circuit is normal, presses the button contacts that the operation of motor forward direction starts A5, then contactor a coil 7 obtains electric, and rotating forward indicator light 11 is bright, and contactor a contact 3 works, and motor 1 starts positive operation, presses Button contacts b6, motor 1 stop working, and rotate forward indicator light 11 and go out.

Power supply power supply in the main circuit control circuit is normal, presses the button contacts of motor inverted running starting C8, then contactor b coil 9 obtains electric, and reversion indicator light 10 is bright, and contactor b contact 4 obtains electric start-up operation, and motor 1 starts reversely to transport Row, presses button contacts b6, and motor 1 stops working, and reversion indicator light 10 goes out.

Specific implementation of the invention: main power source in main circuit generally according to customer demand can be selected AC380V or AC440V；AC220V power supply or AC24V power supply can be selected in the power supply of control circuit, and the power supply of control circuit uses natural heat dissipation piece Pattern；The coil of contactor is located in control route, is mainly used for controlling the operation forward or backwards of motor, the contact of contactor In main line, for being switched off or on motor power；Electrothermal relay is the overload device for protecting motor, when current of electric is super When crossing rated current, then cuts off control and protected；Button is using a dynamic formula button；Indicator light is divided into according to power supply AC220V indicator light or AC24V indicator light.

In Fig. 1-2, when main circuit power and normal control circuit power supply power supply, crewman's situation according to demand, if desired Motor forward direction operation starting button 1SB is then pressed in the operation of unit motor forward direction, then contactor KM coil obtains electric, and forward direction operation refers to Show that lamp 1HL is bright, positive operation contactor main line KM work, motor starts positive operation, presses 2SB stop button, and motor stops Work, indicator light 1HL go out；On the contrary, if desired unit motor inverted running, then press motor inverted running starting button 3SB, then Contactor 1KM coil obtains electric, and inverted running indicator light 2HL is bright, and inverted running contactor main line 1KM work, motor starts reversely Operation, presses 2SB stop button, motor stops working, and indicator light 2HL goes out.In addition, there is motor overload to protect function for this control Can, when motor overload, electrothermal relay FR overload protection disconnects control circuit power supply, and unit stops working.Solve overload problem Afterwards, electrothermal relay overload reset button is pressed, unit restores normal, operates as indicated above again.

Above-described embodiment is only intended to clearly illustrate description made by the present invention, and does not limit the embodiments, To those of ordinary skill in the art, other various forms of variations or change can also be made on the basis of the above description Dynamic, there is no necessity and possibility to exhaust all the enbodiments, and the obvious variation or change thus amplified out It is dynamic to be still in the protection scope of this invention.
