Description

The internal combustion locomotive air compressor heavily joins circuit

Technical field

The present invention relates to a kind of technical field of internal combustion locomotive, especially a kind of internal combustion locomotive air compressor heavily joins circuit.

Background technique

The AC drive passenger internal combustion locomotive of existing phase mutual respect connection, also do not exchange air compressor motor and heavily join function, increased the cost of separate unit passenger train, and in a single day the power supply circuits of 1 air compressor motor break down, air compressor motor can't be worked, even heavily join train and can't move.

Summary of the invention

Lack air compressor motor and heavily join function, separate unit passenger train cost height and the high deficiency of rate of fault in order to overcome existing internal combustion locomotive, the invention provides a kind of internal combustion locomotive air compressor and heavily join circuit.

The technical solution adopted for the present invention to solve the technical problems is: a kind of internal combustion locomotive air compressor heavily joins circuit, comprise power supply, air compressor circuit breaker CMB1, air compressor heavily joins circuit breaker CMB2, air compressor contactor CMC1, air compressor heavily connects tentaculum CMC2, motor M and heavy alliance electricity accessory power outlet XS1, it is characterized in that, power supply heavily joins circuit breaker CMB2 with air compressor circuit breaker CMB1 and air compressor respectively and is connected in series, air compressor circuit breaker CMB1 and air compressor contactor CMC1 are connected in series, air compressor heavily joins circuit breaker CMB2 and heavily connects tentaculum CMC2 with air compressor and be connected in series, air compressor contactor CMC1 and motor M are connected in series, and air compressor heavily connects tentaculum CMC2 and is connected in series with heavy alliance electricity accessory power outlet XS1.

According to another embodiment of the invention, further comprise and be provided with heavy alliance electricity input socket XS2 between air compressor contactor CMC1 and the motor M.

According to another embodiment of the invention, comprise that further heavy alliance electricity accessory power outlet XS1 all is electrically connected with heavy on line L with heavy alliance electricity input socket XS2.

According to another embodiment of the invention, comprise that further motor M is AC motor.

The invention has the beneficial effects as follows that this internal combustion locomotive air compressor heavily joins every AC drive passenger internal combustion locomotive of circuit an air compressor is set, heavily realized the configuration of 2 air compressors behind the connection, reduced the cost of separate unit passenger locomotive, can also play the effect of loss of weight; If the power supply circuits of 1 air compressor motor break down, another locomotive provides power supply by heavy on line for it, guarantees the air compressor motor proper functioning, is easy to use and promotes.

Description of drawings

The present invention is further described below in conjunction with drawings and Examples.

Fig. 1 is circuit diagram of the present invention;

Fig. 2 is the circuit diagram of the embodiment of the invention one.

Embodiment

Be circuit diagram of the present invention as Fig. 1, a kind of internal combustion locomotive air compressor heavily joins circuit, comprise power supply, air compressor circuit breaker CMB1, air compressor heavily joins circuit breaker CMB2, air compressor contactor CMC1, air compressor heavily connects tentaculum CMC2, motor M and heavy alliance electricity accessory power outlet XS1, it is characterized in that, power supply heavily joins circuit breaker CMB2 with air compressor circuit breaker CMB1 and air compressor respectively and is connected in series, air compressor circuit breaker CMB1 and air compressor contactor CMC1 are connected in series, air compressor heavily joins circuit breaker CMB2 and heavily connects tentaculum CMC2 with air compressor and be connected in series, air compressor contactor CMC1 and motor M are connected in series, air compressor heavily connects tentaculum CMC2 and is connected in series with heavy alliance electricity accessory power outlet XS1, be provided with heavy alliance electricity input socket XS2 between air compressor contactor CMC1 and the motor M, heavy alliance electricity accessory power outlet XS1 all is electrically connected with heavy on line L with heavy alliance electricity input socket XS2, and motor M is AC motor.

During use, when multi-locomotive normally drew, all circuit breakers were in closed state, and air compressor heavily connects tentaculum CMC2 and is in off state, and the air compressor power supply of locomotive is powered to air compressor motor through circuit breaker and contactor; If power failure or circuit breaker failure when motor M can't be worked, disconnect air compressor contactor CMC1 contact by air compressor circuit breaker CMB1 control circuit; If air compressor contactor CMC1 breaks down, as contact adhesion or scaling loss and can not work the time, the artificial air compressor circuit breaker CMB1 that disconnects, cut off the A car to the circuit of air compressor motor M power supply, give the air compressor motor M power supply of this locomotive then by another chassis that heavily joins, two air compressor proper functioning when guaranteeing the multi-locomotive operation

Embodiment one:

As shown in Figure 2, the A car joins with the mutual respect of B car phase, the electrical configurations of every chassis is identical, heavily joining circuit breaker, air compressor contactor, air compressor by power supply, air compressor circuit breaker, air compressor respectively heavily connects tentaculum, motor, heavy alliance electricity accessory power outlet, heavy alliance electricity input socket and heavy on line and forms, when multi-locomotive normally draws, all circuit breakers are in closed state, air compressor heavily connects tentaculum CMC2 and heavily connects tentaculum CMC4 with air compressor and be in off state, and the air compressor power supply of every chassis is given the power supply of air compressor motor separately through circuit breaker and contactor; Be example with the A car, if A car power failure or circuit breaker failure, when motor M can't be worked, the air compressor circuit breaker CMB1 control circuit by the A car disconnected air compressor contactor CMC1 contact; If A car air compressor contactor CMC1 breaks down, as contact adhesion or scaling loss and can not work the time, the artificial air compressor circuit breaker CMB1 that disconnects the A car, cut off the A car to the circuit of air compressor motor power supply, air compressor by the B car heavily joins the closed air compressor of circuit breaker CMB4 control circuit and heavily connects tentaculum CMC4 then, the air compressor motor M of A car heavily joins circuit breaker CMB4 by the air compressor power supply of B car through air compressor at this moment, air compressor heavily connects tentaculum CMC4, heavy alliance electricity accessory power outlet XS4 and heavy on line CLL, heavy alliance electricity input socket XS2 via the A car powers for the air compressor motor M of A car again, two air compressor proper functioning when guaranteeing the multi-locomotive operation.

This internal combustion locomotive air compressor heavily joins every AC drive passenger internal combustion locomotive of circuit an air compressor is set, and has heavily realized the configuration of 2 air compressors behind the connection, has reduced the cost of separate unit passenger locomotive, can also play the effect of loss of weight; If the power supply circuits of 1 air compressor motor break down, another locomotive provides power supply by heavy on line for it, guarantees the air compressor motor proper functioning, is easy to use and promotes.
