Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without any creative effort belong to the protection scope of the present invention.

As shown in fig. 1, a cone crushing main control circuit includes a motor, a start-stop control circuit, a decompression start protection circuit, a start detection circuit, a switching circuit, and an operation indication circuit, where the start-stop control circuit is used to control the start or stop of a main loop, the motor is connected to a power supply through the switching circuit, the motor is also connected to the power supply through the decompression start protection circuit and the switching circuit, the start detection circuit controls the switching circuit according to start information of the motor, and the operation indication circuit is used to indicate an operation state of the indication control circuit.

Specifically, before the main engine is started, whether the lubrication of the oil station is normal or not is judged firstly, that is, under the condition that an oil station interlocking switch K is closed, the starting indicator light HR4 is allowed to be turned on at the moment. When a starting button SB1 is pressed, the star point contactor KM1 is electrified and attracted, the auxiliary normally open contact KM1 is closed, the contactor KM2 is triggered to attract, and the motor is started after being connected with a power supply through the self-coupling voltage regulator TAT and starts to start in a voltage reduction mode. At this time, the start indicator light HY is turned on, and the operation indicator lights HR1 and HR2 are turned on. The self-coupling voltage regulator TAT reduces the starting current to 65% of the rated current, so that the starting current is greatly reduced, and the impact on a power grid is reduced. Meanwhile, an auxiliary normally open contact of the contactor KM2 is closed, so that the time current relay KT starts to time, after a preset delay time, the contact of the time current relay KT is closed, the actuation of the intermediate relay KA is controlled, and the normally closed contact is opened after the actuation of the intermediate relay KA, so that the star point contactor KM1 is disconnected; meanwhile, after the intermediate relay KA is sucked, the normally open contact is closed, so that the main contactor KM3 is connected, and the contactor KM2 is disconnected, so that switching and starting are completed. At this time, the operation indicator lamp HG is turned on, and the start indicator lamp HY is turned off. The buttons SB1 and SB4 are pressed directly, using conventional actuation.

Preferably, the time current relay KT also collects the current value of the host through current transformers TA1 and TA2, and when the host is judged to be started according to the collected current value, the time current relay KT is directly controlled to be closed by a contact without waiting for delay time, so that the intermediate relay KA is controlled to be attracted and automatically switched. Wherein IF is a current transmitter, VF is a voltage transmitter, and is used for collecting working current and voltage and transmitting the working current and voltage to a lubricating oil station control system. Specifically, after the star point contactor KM1 is electrified, the auxiliary normally closed contact is disconnected, the current transformers TA1 and TA2 induce currents to act on the time current relay KT, and the time current relay KT is directly triggered to work when the current value reaches a preset value. After the intermediate relay KA is pulled in, the auxiliary normally closed contact is opened, meanwhile, the star point contactor KM1 is powered off, the auxiliary normally closed contact is closed, and at the moment, the inductive currents of the current transformer TA1 and TA2 are transmitted through the current transmitter. Wherein KH is a thermal protector.

QF is breaker, button SB2 is local stop button, button SB6 is remote start button, button SB5 is remote stop button, and FU1-FU4 is self-recovery fuse.

It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
