Abstract
The utility model relates to a comprehensive compensation soft start device for a winding motor, which belongs to the technical field of motor control and regulation and solves the shortcomings that the winding motor in the prior art adopts frequency-sensitive resistance start method and adopts a mechanical rotary type contact phase advancer for phase advance. The utility model adopts the technical scheme as follows: a water resistance soft start device A and a rotor short-circuit contactor KM2 are serially connected to form a water resistance soft start circuit, and a current/voltage phase advance compensation device B is serially connected with a rotor short-circuit contactor KM3 to form a current/voltage phase advance compensation circuit; and a rotor short-circuit contactor KM1, the water resistance soft start circuit and the current/voltage phase advance compensation circuit are parallelly connected and then connected into a motor rotor circuit. The comprehensive compensation soft start device has the benefits as follows: the device reduces motor start current, meets the start demands of different loads, increases the power factor during motor operation to 0.98 or higher, reduces the shock to power grid when starting, and (5) the device has the advantages of small volume, simple structure, low cost and convenient use and maintenance.
Description
Technical field
The utility model belongs to the control and the regulation technology field of motor, relates to a kind of device that is used for starting motor.
Background technology
Because coiling electric motor load major part is heavy duty, power factor reaches 0.85 during operation, the jogging mode is adopted in the startup of winding motors at present more, when reducing motor start-up to the impact of electrical network, power back-off adopts mechanical rotation formula contact phase advancer to advance the phase mode, power factor when improving the motor operation.Its subject matter is, quick resistance soft start starting current is big frequently, reaches 3～4 times in motor amount electric current, and phase advancer contact fault affected by environment in mechanical rotation formula contact is many, is subjected to compensation precision to influence power factor and can only mends 0.95.
Summary of the invention
The purpose of this utility model is to overcome existing coiling electric motor soft starter device and advances mutually with mechanical rotation formula contact phase advancer and exist deficiency to provide a kind of staring torque big in the mode, starting current is little, reduction is to the influence of public electric wire net, and it is simple in structure, dependable performance, cost is low, and working service is winding motors comprehensive compensation soft starter device easily.
Technical solutions of the utility model are: a kind of winding motors comprehensive compensation soft starter device, its water resistance soft starter device A and rotor short circuit contactor KM2 are composed in series the water resistance soft starting circuit, and electric current, voltage advance mutually compensation and advances to install mutually that B is composed in series electric current with rotor short circuit contactor KM3, voltage advances compensating circuit mutually; Rotor short circuit contactor KM1, water resistance soft starting circuit enter the compensating circuit rotor loop of inserting in parallel mutually with electric current, voltage.
The utility model adopts a kind of brand-new comprehensive compensation Starting mode to realize its goal of the invention.Compared with prior art, advantage of the present utility model is:
1, reduces the motor start-up electric current.Water resistance soft start starting current of the present utility model is little, and staring torque is big, and starting current only is 1.3 times in a motor amount electric current.
2, in motor operation course motor power factor is compensated, power factor reaches more than 0.98 when improving the motor operation.After coiling electric motor started, the electric current in rotor loop, voltage advanced the phase compensation arrangement and adopt the AC/AC (alternating current) variable-frequency technology, contactless when providing certain frequency, out of phase voltage and electric current to improve the motor operation for the rotor loop power factor reach 0.98.
3, satisfy different loads and start demand;
When 4, reducing electric motor starting to the impact of electrical network;
5, volume is little, simple in structure, cost is low, dependable performance, working service convenient.
Description of drawings
The utility model is described in further detail below in conjunction with embodiment that accompanying drawing provides.
Accompanying drawing is circuit theory diagrams of the present utility model.
Embodiment
Among the embodiment of accompanying drawing, QF is the motor run switch, water resistance soft starter device A and rotor short circuit contactor KM2 are composed in series the water resistance soft starting circuit, and electric current, voltage advance that phase compensation arrangement B is composed in series electric current with rotor short circuit contactor KM3, voltage advances compensating circuit mutually; Rotor short circuit contactor KM1, water resistance soft starting circuit enter the compensating circuit rotor loop of inserting in parallel mutually with electric current, voltage.The water resistance soft starter device A model that adopts in the present embodiment is XBTYDQ type water resistance soft starter device (manufacturer Xiangfan new hundred special automation equipment Co., Ltd), and electric current, voltage advance compensation compensation mutually and advances to install mutually Type B number and advance mutually device (manufacturer Xiangfan new hundred special automation equipment Co., Ltd) for XBTEJ6 type electric current, voltage advance compensation compensation mutually.Water resistance soft starter device A connects the motor M rotor loop by rotor short circuit contactor KM2, and electric current, voltage advance phase compensation arrangement B and connects the motor M rotor loop by rotor short circuit contactor KM3.When electric motor starting front motor run switch QF disconnection, rotor short circuit contactor KM2 closure, rotor short circuit contactor KM1, rotor short circuit contactor KM3 disconnect.Motor M was in and treated starting state this moment, after starter motor run switch QF closes a floodgate, motor M begins to start, when motor speed during near the amount rotating speed, rotor short circuit contactor KM1 closure, rotor short circuit contactor KM2 disconnects, after a few minutes, rotor short circuit contactor KM3 closure, rotor short circuit contactor KM1 disconnects, and this moment, motor entered the operation compensating coefficient.
