Description

The internal combustion locomotive air compressor heavily joins circuit

Technical field

The utility model relates to a kind of technical field of internal combustion locomotive, and 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 have the ac air compressor motor heavily to 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, and even heavily joining train can't move.

The model utility content

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

the technological scheme that its technical problem that solves the utility model adopts 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, 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 present utility model, further comprise between air compressor contactor CMC1 and motor M and be provided with heavy alliance electricity input socket XS2.

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

, according to another embodiment of the present utility model, comprise that further motor M is AC motor.

The beneficial effects of the utility model are, this internal combustion locomotive air compressor heavily joins every AC drive passenger internal combustion locomotive of circuit an air compressor is set, heavily realize the configuration of 2 air compressors after 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 normal operation, is easy to use and promotes.

Description of drawings

Below in conjunction with drawings and Examples, the utility model is further illustrated.

Fig. 1 is circuit diagram of the present utility model;

Fig. 2 is the utility model embodiment one circuit diagram.

Embodiment

circuit diagram of the present utility model 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 motor M, heavy alliance electricity accessory power outlet XS1 all is electrically connected to heavy on line L with heavy alliance electricity input socket XS2, 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 circuit of A car to air compressor motor M power supply, then pass through the air compressor motor M power supply of another chassis that heavily joins to this locomotive, while guaranteeing the multi-locomotive operation, two air compressors work

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, take the A car as example, if A car power failure or circuit breaker failure, when motor M could be worked, by the air compressor circuit breaker CMB1 control circuit disconnection air compressor contactor CMC1 contact of A car, 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 circuit of A car to the air compressor motor power supply, then the air compressor by the B car heavily joins the closed air compressor of circuit breaker CMB4 control circuit and heavily connects tentaculum CMC4, 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, again via the air compressor motor M power supply of the electric input socket XS2 of the heavy alliance of A car to the A car, two air compressor normal operations while 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 after 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 normal operation, is easy to use and promotes.
