Abstract
An independent power supply dual motor one-to-two starting system comprises two independent control loops, the first control loop comprises a soft starter SFR, a breaker 1QF, an intermediate relay KM5, an intermediate relay KM1, an intermediate relay KM2 and a thermorelay KH1, and the second control loop comprises the soft starter SFR, a breaker 2QF, an intermediate relay KM6, an intermediate relay KM3, an intermediate relay KM4 and a thermorelay KH2. The beneficial effects of the utility model are that an original power supply system is not changed, and by just configuring one soft starter, two asynchronous motors can be started, so that the soft starting cost is reduced, and a one-to-two starting control mode is realized.
Description
Technical field
The utility model relates to a kind of bi-motor start-up system, particularly a kind of independently-powered bi-motor one drag two start-up system.
Background technology
In actual motion, adopt at present the motor of star delta reduced-voltage starting and auto coupling decompression start mode also to occupy very large proportion.But because it adopts the discrete component assembling, the control circuit contact is more, and is in service at it, and particularly in the place of work condition environment abominable (such as dust, humidity), failure rate is relative still higher, and for the startup of bi-motor, start-up cost is also higher.
Summary of the invention
The purpose of this utility model is to address the above problem, and a kind of power supply, low independently-powered bi-motor one drag two start-up system of cost need do not transformed is provided.
The technical solution of the utility model is: comprise two independently control loops, article one, control loop comprises soft initiator SFR, circuit breaker 1QF, auxiliary relay KM5, auxiliary relay KM1, auxiliary relay KM2, thermal relay KH1, the end of circuit breaker 1QF connects power supply, circuit breaker 1QF, auxiliary relay KM2, thermal relay KH1 is connected in series successively, the other end of thermal relay KH1 is connected between auxiliary relay KM1 and the motor M 1, one of described auxiliary relay KM5 terminates between circuit breaker 1QF and its KM2, the other end links to each other with soft initiator SFR, the end of described auxiliary relay KM1 links to each other with soft initiator SFR, and the other end links to each other with motor M 1; The second control loop comprises soft initiator SFR, circuit breaker 2QF, auxiliary relay KM6, auxiliary relay KM3, auxiliary relay KM4, thermal relay KH2, the end of circuit breaker 2QF connects power supply, circuit breaker 2QF, auxiliary relay KM4, thermal relay KH2 is connected in series successively, the other end of thermal relay KH2 is connected between auxiliary relay KM3 and the motor M 2, one of described auxiliary relay KM6 terminates between circuit breaker 2QF and its KM4, the other end links to each other with soft initiator SFR, the end of described auxiliary relay KM3 links to each other with soft initiator SFR, and the other end links to each other with motor M 2.
The beneficial effects of the utility model are: the utility model does not change former powersupply system, only need dispose a soft initiator when adopting two asynchronous motor startings, has reduced the soft start cost, with the control mode that realizes that one drag two starts.
Description of drawings

Fig. 2 is control loop schematic diagram of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing and example.
Referring to Fig. 1, Fig. 1 is major loop connection diagram of the present utility model, there is shown soft initiator SFR, circuit breaker 1QF, auxiliary relay KM5, auxiliary relay KM1, auxiliary relay KM2, thermal relay KH1, circuit breaker 2QF, auxiliary relay KM6, auxiliary relay KM3, auxiliary relay KM4, thermal relay KH2, the end of circuit breaker 1QF connects power supply, circuit breaker 1QF, auxiliary relay KM2, thermal relay KH1 is connected in series successively, the other end of thermal relay KH1 is connected between auxiliary relay KM1 and the motor M 1, one of described auxiliary relay KM5 terminates between circuit breaker 1QF and its KM2, the other end links to each other with soft initiator SFR, the end of described auxiliary relay KM1 links to each other with soft initiator SFR, the other end links to each other with motor M 1, the end of circuit breaker 2QF connects power supply, circuit breaker 2QF, auxiliary relay KM4, thermal relay KH2 is connected in series successively, the other end of thermal relay KH2 is connected between auxiliary relay KM3 and the motor M 2, one of described auxiliary relay KM6 terminates between circuit breaker 2QF and its KM4, the other end links to each other with soft initiator SFR, the end of described auxiliary relay KM3 links to each other with soft initiator SFR, and the other end links to each other with motor M 2.
Referring to Fig. 2, manual operation SCA1 (or automatically control) connects auxiliary relay KM1 and KM5, and auxiliary relay KM3 not electric, after the start loop smooth start with motor M1 access soft initiator SFR, auxiliary relay KM2 is connected in the Bypass Control enabling signal expansion of soft initiator, and time-delay disconnection auxiliary relay KM1 and KM5, so far motor M1 switches to normal operating loop powered operation.So same manual operation SCA2 (or automatically control) connects auxiliary relay KM3 and KM6, and auxiliary relay KM1 not electric, after the start loop smooth start with motor M2 access soft initiator, auxiliary relay KM4 is connected in the Bypass Control enabling signal expansion of soft initiator, and time-delay disconnection auxiliary relay KM3 and KM6, so far motor M2 switches to normal operating loop powered operation.The Bypass Control enabling signal of soft initiator extends to two and overlaps independently control loop, and its signal extension auxiliary relay two overlaps independently control loop dual power supply by this.
This example is two 37kW asynchronous motors by the separate power supply power supply of two-way, overlaps independently control loop by two, and two overlap control loop independently and realize respectively control to a soft initiator, to realize the one drag two starting.
