The auxiliary switch is arranged over the bottom armature equipped with a coil. The bottom insulating rack is fixedly equipped with a heat dissipating hole, a vacuum arc-extinguishing chamber, and a sealing device. The heat dissipating hole is disposed on the top of the vacuum arc-extinguishing chamber. The sealing device is disposed on the bottom of vacuum arc-extinguishing chamber. The vacuum contactor has characteristics of effectively saving cost, satisfying multiple usage occasions, achieving unrestricted use fields, having good heat dissipating performance and sealing performance, and prolonging the service life of the vacuum contactor to a certain extent.
Description
Technical field
The utility model relates to a kind of electric switch equipment, particularly a kind of vacuum contactor.
Background technology
Existing vacuum contactor is applicable to that mainly the major loop rated operational voltage at 1140 volts once, the electric power system of rated operational current below 600 peaces reach, connect and the disjunction circuit reaches and starts continually and control motor for remote, but because this restriction, can't be applicable to 3300 volts electrical network, network system for 3300 volts, can only adopt bulky vacuum contactor at present, but so not only floor space is big, and application also has been subjected to considerable restraint, and this type of vacuum contactor fault is also than higher, often maintenance, be unfavorable for the saving of cost, therefore need make certain improvement to it, just can better meet the demand in market.
The utility model content
The purpose of this utility model just is to provide a kind of vacuum contactor, can address the above problem fully.
To achieve these goals, the technical solution adopted in the utility model is such: vacuum contactor of the present utility model, comprise base, be provided with electromagnetic controller in the base, be respectively equipped with insulating frame and following insulating frame on the base, be installed with auxiliary switch, lower armature and electronic circuit board on the last insulating frame respectively, lower armature is provided with coil, auxiliary switch is positioned at the lower armature top, be installed with louvre, vacuum interrupter and sealing device respectively on the following insulating frame, louvre is arranged on the vacuum interrupter top, and sealing device is arranged on the vacuum interrupter bottom.
As preferably, described vacuum interrupter is 3300 volts, 600 peaces.
As preferably, the described wall thickness of insulating frame of going up is between seven millimeters to nine millimeters.
As preferably, the wall thickness of described insulating frame down is between six millimeters to seven millimeters.
As preferably, be provided with circuit protection device in the described electromagnetic controller.
Compared with prior art, advantage of the present utility model is: vacuum interrupter is 3300 volts, 600 peaces, and such design can be satisfied 3300 volts design voltage; The wall thickness of last insulating frame is between seven millimeters to nine millimeters, and the wall thickness of following insulating frame is between six millimeters to seven millimeters, and is reasonable in design, and is too thin and too thickly all can influence its result of use; Be provided with circuit protection device in the electromagnetic controller, make its function with integrated circuit protection, further protected the electrical property of using of vacuum contactor; This vacuum contactor has effectively been saved cost, can satisfy more use occasion, and the use field is unrestricted, and heat dispersion and sealing property are all good, has prolonged the useful life of vacuum contactor to a certain extent.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Referring to Fig. 1; vacuum contactor of the present utility model; comprise base 1; be provided with electromagnetic controller 2 in the base 1; be respectively equipped with insulating frame 3 and following insulating frame 7 on the base 1; be installed with auxiliary switch 4 respectively on the last insulating frame 3; lower armature and electronic circuit board 6; lower armature is provided with coil 5; auxiliary switch 4 is positioned at the lower armature top; be installed with louvre 8 respectively on the following insulating frame 7; vacuum interrupter 9 and sealing device 10; louvre 8 is arranged on vacuum interrupter 9 tops; sealing device 10 is arranged on vacuum interrupter 9 bottoms, and described vacuum interrupter 9 is 3300 volts; 600 peaces, the described wall thickness of insulating frame 3 of going up is between seven millimeters to nine millimeters; the wall thickness of described insulating frame 7 down is provided with circuit protection device in the described electromagnetic controller 2 between six millimeters to seven millimeters.
This vacuum contactor has effectively been saved cost, can satisfy more use occasion, and the use field is unrestricted, and heat dispersion and sealing property are all good, has prolonged the useful life of vacuum contactor to a certain extent.Be provided with electromagnetic controller 2 in the base 1, eliminated eccentric force, last insulating frame 3 and following insulating frame 7 are by being bolted on the base 1, last insulating frame 3 and following insulating frame 7 are connected by support, auxiliary switch 4 is located at the lower armature top, and be electrically connected with the supply unit that is arranged on vacuum contactor inside, lower armature one end is fixed on insulating frame 3 surfaces, electronic circuit board 6 is electrically connected with coil 5, when coil 5 dead electricity or coil 5 both end voltage significantly reduced, lower armature will discharge, and auxiliary switch 4 will be opened, vacuum contactor just breaks away from operating state, normally opened contact will be closed, and normally-closed contact will be opened, thereby keeps the work of coil 5, vacuum interrupter 9 is 3300 volts, 600 peaces, make its electrical network that is applicable to 3300 volts, the wall thickness of last insulating frame 3 is between seven millimeters to nine millimeters, and the wall thickness of following insulating frame 7 is between six millimeters to seven millimeters, strengthened reliability, reasonable in design; Be provided with circuit protection device in the electromagnetic controller 2, make its function with integrated circuit protection, further protected the electrical property of using of vacuum contactor.
The above only is a preferred embodiment of the present utility model, so all equivalences of doing according to the described structure of the utility model patent claim, feature and principle change or modify, is included in the protection range of the utility model patent application.
