Description
Technical field
The utility model relates to a kind of motor starter, particularly a kind of built in bypass type motor soft starter.
Background technology
At present, every motor that needs reduced-voltage starting adopts the electronics soft starting device mostly, and it both can reduce motor and directly start the impact that brings to driven equipment, and big electric current is to the impact of electrical network in the time of can reducing motor start-up again.Existing external motor soft starter all adopts the on-line operation bypass operational mode of holding concurrently, and the direct-on-line that in use has uses, and the bypass that has is used.During online use, because the silicon controlled power consumption is quite big, so the energy consumption increase; In order to guarantee heat radiation, must adopt machinery air-cooled, therefore cause the soft starting device complicated integral structure and bulky.Be not subjected to the influence of hot blast simultaneously for other device for switching, guarantee that its electric performance stablity is reliable, therefore adopt the complete sets of equipment volume more to increase.In order to improve above-mentioned deficiency, the designer sets up a cover bypass running gear again, torque and starting current in order to control motor during motor start-up, adopt soft starting device, start back contactor shunting device operation, the controllable silicon of soft starting device is promptly closed, and the controllable silicon power consumption of soft starting device is near zero like this.Though above measure has solved the excessive deficiency that causes of soft starting device on-line operation power consumption, but causes circuit system complicated, failure rate improves, and maintenance capacity increases.From the function of use angle analysis, this device is applicable to the not too occasion of frequent starting.However, people still adopt the latter in the occasion of frequent starting not too.Along with this field scientific research technical staff's continuous exploration, technology and market are all in expansion forward.Domestic manufacturer is from use angle, mostly the direct soft starting device of production bypass operational mode.
The utility model content
The purpose of this utility model is to overcome above-mentioned weak point, the confined space that makes full use of in the soft starting device housing makes its formation rationally distributed, a kind of dependable performance, energy-saving and cost-reducing is provided, reduced volume, reduces cost, wholely constitute incorporate built in bypass type motor soft starter.Make the three-phase AC asynchronous motor of its 75 kilowatts of adaptive startup and following all size.
The technical scheme that the utility model adopted is for achieving the above object: a kind of built in bypass type motor soft starter, and the controllable silicon, current transformer, contactor, transformer and the display keyboard that are connected respectively by housing, radiator, conductor and control circuit board are constituted; It is characterized in that display keyboard is revealed in surface of shell, a side is provided with transformer, and conductor, current transformer link to each other, and controllable silicon places on the radiator fixedlys connected with housing, and the adjacent contactor that is provided with is that three extremely integrated contactors are arranged in the housing.
Described control circuit board connects controllable silicon, current transformer, contactor, transformer, display keyboard respectively by lead; The control circuit board input connects power supply, and output connects controlled motor by controllable silicon, contactor.
Described contactor is the triple pole contactor of E type electromagnetic core structure.
Described controllable silicon adopts the bidirectional triode thyristor module.
The utility model has the advantages that: the confined space that makes full use of in the soft starting device housing makes its compact conformation, rationally distributed, and its specific structure designs reduced volume greatly, forms apparatus integration.Energy-saving and cost-reducing, reduce cost, effectively guarantee contact reliability and make himself on-line operation zero-power.This device provides level and smooth progressive start-up course to motor, reduces the impact of starting current to electrical network, reduces the vibration and the noise of equipment, the useful life of prolonged mechanical drive system.The scope of application is very extensive, as motor start-up of water pump, blower fan, compressor, conveying machinery equipment etc.

Fig. 2 is Fig. 1 vertical view;
Fig. 3 be Fig. 1 along A-A to structural representation;
Fig. 4 be Fig. 2 along B-B to structural representation;
Fig. 5 is the utility model control circuit board and control assembly connection diagram.
Among the figure: 1 housing, 2 radiators, 3 conductors, 4 control circuit boards, 5 controllable silicons, 6 current transformers, 7 contactors, 8 transformers, 9 display keyboards.
Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, details are as follows to embodiment, structure, feature that foundation the utility model provides:
Referring to Fig. 1～Fig. 5, the controllable silicon 5 that the utility model is connected respectively by housing 1, radiator 2, conductor 3 and control circuit board 4, current transformer 6, contactor 7, transformer 8 and display keyboard 9 are constituted; It is characterized in that display keyboard 9 is revealed in housing 1 surface, a side is provided with transformer 8, and conductor 3, current transformer 6 link to each other, and controllable silicon 5 places on the radiator 2 fixedlys connected with housing 1, and the adjacent contactor that is provided with is that three extremely integrated contactors are arranged in the housing 1.
Referring to Fig. 5, described control circuit board 4 connects controllable silicon 5, current transformer 6, contactor 7, transformer 8, display keyboard 9 respectively by lead; Control circuit board 4 inputs connect power supply, and output connects controlled motor M by controllable silicon 5, contactor 7.
Described contactor 7 is the triple pole contactor of E type electromagnetic core structure.
Every two fixed contacts extremely going up of contactor can in parallelly use, and promptly the moving contact of contactor and fixed contact are used as two contact electrodes, and the rated current of contactor is doubled.
Described controllable silicon 5 adopts the bidirectional triode thyristor module.
Because the controllable silicon of this device moves when just starting in short-term, so the silicon controlled type selecting is less, moreover contactor substitutes controllable silicon bypass operation when normally moving, make its power consumption near zero, therefore do not need mechanical draft, volume dwindles greatly, and specific volume is suitable mutually with bypass type.The function and the advantage of this device collection all kinds starting drive are maximized favourable factors and minimized unfavourable ones.Thereby high power consumption, high heat when having solved the controllable silicon on-line operation distribute the drawback that is caused.In order to guarantee effect, carry out different structural designs for different size, this device adapts to the three-phase AC asynchronous motor of 75 kilowatts and following all size especially.
