Detailed Description

The first embodiment is as follows: please refer to fig. 1 and 3, the utility model discloses a building site mortar machine reforms transform control switch, including mortar machine 1, switch box 2 and setting electric leakage circuit breaker 3 and fuse 4 in switch box 2, still include secondary switch control circuit, secondary switch control circuit includes button switch 5, transformer 6, contactor 7 and thermal overload relay 8 all set up in switch box 2, button switch 5 sets up in mortar machine 1 one side, and button switch 5 adopts waterproof box installation. The contactor 7 and the button switch 5 are electrically connected to form a control circuit 9, the input end of the transformer 6 is connected with the power supply, the output end of the transformer is connected with the input end of the control circuit 9, the transformer 6 is used for reducing the 380V power supply voltage to 36V and outputting the power supply voltage to the control circuit 9, and the thermal overload relay 8, the leakage circuit breaker 3 and the fuse 4 are sequentially electrically connected to form a protection circuit.

In the first embodiment, two fuses 4 are arranged in the protection circuit, which are a first fuse 41 and a second fuse 42 respectively, the input end of the transformer 6 is connected with a power supply, the input end of the transformer obtains 380V voltage, for safety, the first fuse 41 is further arranged in the circuit connecting the power supply and the transformer 6, the output end of the transformer 6 is connected with the control circuit 9, the button switch 5 preferably comprises two jog button switches, the two jog button switches 51 are a first jog button 511 and a second jog button 512 respectively, the first jog button 511 is a normally closed switch, the second jog button 512 is a normally open switch, the control circuit 9 further comprises a contactor 7, the contactor 7 comprises a contactor coil 71 and a normally open contact 72, the second fuse 42, the first jog button 41, the second jog button 512 and the contactor coil 71 are electrically connected in sequence, the control circuit 9 further comprises a self-locking control circuit 10, and the self-locking control circuit 10 is realized by connecting the second jog button 512 and the normally open contact 72 of the contactor 7 in parallel.

The simple circuit principle of the push-button switch is as follows: the method comprises the steps that 380V voltage is transformed to 36V through a transformer 6, then the 36V voltage is output to a control circuit 9, then a second jog button 512 is pressed, a contactor coil 71 is electrified, a normally open contact 72 of a contactor 7 is closed, the mortar machine 1 is started, and even if the second jog button automatically rebounds 512, the mortar machine 1 still normally works due to the existence of a self-locking circuit 10; when the first start button 511 is pressed down, the contactor coil 71 loses power, and the mortar machine 1 stops working immediately; the embodiment of the utility model provides a first control button switch 5 realizes the start-up and shut-down of mortar machine 1 through simple point.
