Abstract
The utility model relates to an air compressor soft starter connecting structure adopting the internal connection mode. The air compressor soft starter connecting structure comprises a soft starter, a motor and a bypass contactor. The incoming line end of the soft starter is connected with a three-phase power source, two ends of the bypass contactor are connected with the three-phase power source and the contactor connecting end of the soft starter respectively, and two ends of the motor are connected with the three-phase power source and the power end of the soft starter respectively. Compared with the prior art, according to the utility model, the cost can be reduced, the overall size can be reduced, and the advantage of convenient maintenance can be realized.
Description
Technical field
The utility model relates to a kind of air compressor, especially relates to a kind of air compressor soft initiator syndeton that adopts interior connection.
Background technology
The connection of existing main motor soft starter adopts the soft initiator method for externally, there is starting current than the starting of existing star triangle little, more steady, the characteristics that noise is less, but soft start equipment is more expensive more than 5 times than star triangle starting equipment, and soft initiator takes up space greatlyr as electric equipment independently, the inner space of air compressor machine is proposed to higher requirement, so be not easy extensively to push open market in application.
The utility model content
The purpose of this utility model is exactly to provide a kind of air compressor soft initiator syndeton that adopts interior connection in order to overcome the defect that above-mentioned prior art exists, and this syndeton can reduce costs, reduce overall dimensions, and maintenance is convenient.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of air compressor soft initiator syndeton that adopts interior connection, comprise soft initiator, motor and bypass contactor, the end of incoming cables of described soft initiator connects three phase mains, the two ends of described bypass contactor connect respectively the contactor link of three phase mains and soft initiator, and the two ends of described motor connect respectively the power end of three phase mains and soft initiator.
Described bypass contactor is the open type contactor, and during the bypass contactor adhesive, soft initiator disconnects.
Compared with prior art, the utlity model has following advantage:
One, reduce costs: the soft initiator type selecting is as long as consider according to interior connection, and as long as capacity is just passable according to 1/1.732 choosing of method for externally, so that the type selecting of soft initiator just can be selected is little.
Two, installing space is little: the design size that can reduce whole equipment.
Three, maintenance is convenient: change soft initiator convenient.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.
Embodiment
As shown in Figure 1, a kind of air compressor soft initiator syndeton that adopts interior connection, comprise soft initiator Soft, motor M 1 and bypass contactor KM2.Soft initiator Soft is provided with end of incoming cables, power end and contactor link, wherein three of end of incoming cables terminal L1, L2, L3 connect respectively three inlet wires of three phase mains, the two ends of bypass contactor KM2 connect respectively three terminal A2, B2, the C2 of the contactor link of three phase mains and soft initiator Soft, outlet U1, the V1 of motor M 1, W1 connect respectively three terminal T1, T2, the T3 of the power end of soft initiator Soft, and another road outlet U2, V2, W2 connect three phase mains.
When motor needs soft start, soft initiator is by progressively being pressurizeed with motor U1, V1, W1 terminal, make motor slowly rotate, when voltage or electric current reach rated voltage or rated current 85% the time, bypass contactor KM2 adhesive, soft start disconnects, and motor just starts to work under normal voltage, and the starting of motor completes.
Claims (2)
1. the air compressor soft initiator syndeton of connection in an employing, comprise soft initiator, motor and bypass contactor, the end of incoming cables of described soft initiator connects three phase mains, the two ends of described bypass contactor connect respectively the contactor link of three phase mains and soft initiator, it is characterized in that, the two ends of described motor connect respectively the power end of three phase mains and soft initiator.
