Abstract
The utility model provides a 200A high-power direct-current (DC) contactor. The 200A high-power DC contactor comprises two stationary contacts which are arranged in parallel, wherein a movable contact which can be contacted with the stationary contacts is arranged below the stationary contacts; the stationary contacts and the movable contact are arranged in a sealed ceramic cavity; and a reciprocation driving mechanism is connected to the lower part of the movable contact. The contactor can control the turning-on and turning-off of 200 A and 320 V DC current and is small in appearance size; a ceramic sealed contact bin is filled with nitrogen; an electric arc cannot be generated during turning-on and turning-off of a large load; strong magnets are arranged on two sides of each stationary contact and used for extinguishing the arc; the contactor is provided with an energy-saving plate; the temperature rising speed of coils is extremely low; and an epoxy material and a sealing copper tube are used for double seal, and the contactor has high sealing performance.
Description
Technical field
The utility model relates to electric power accessory technical field, concrete relates to a kind of high power DC contactor that can control the DC motor break-make.
Background technology
Existing high-power contactor mainly is by magnetic circuit part, running part and contact branch constitutes, and the guiding distance of running part is long, and the contact area between the metal is big, and the running part motion need overcome big resistance, and the product power consumption is big.And contact portion is prone to produce electric arc, and security performance and insulation property reduce greatly, and it is unreliable to work.
The utility model content
The utility model technical problem to be solved is, overcomes the problem that exists in the prior art, provides a kind of novel, reliable in quality, flexible movements, load current greatly, not to produce the high power DC contactor of electric arc.
For the technical scheme that addresses the above problem the utility model is such:
A kind of 200A high power DC contactor; Comprise two fixed contacts that are arranged side by side; Fixed contact below is provided with the moving contact that can touch with fixed contact; Fixed contact and moving contact are arranged in the sealing iron-clad cavity, and the moving contact below connects a reciprocating drive mechanism, pass through epoxy sealing between fixed contact and the sealing iron-clad cavity.
Reciprocating drive mechanism comprises an axle movable up and down; Moving contact is installed on the axle, is with moving iron core on the axle, is with the compression spring on the axle of moving contact below; The axle of moving position unshakable in one's determination is provided with back-moving spring; Moving arranged outside unshakable in one's determination has axle bush, and the axle bush arranged outside has coil, and coil connects an Energy Saving Control plate.
Be filled with nitrogen in the iron-clad cavity.
The top, epoxy sealing place of sealing iron-clad cavity is an enclosing cover, and the enclosing cover top is provided with a sealing copper pipe.
The both sides of two fixed contacts are provided with the permanent magnet that is used for magnetic quenching.
Beneficial effect, the described contactor of the utility model can carry 200A, the break-make of 320VDC electric current; Profile is little, iron-clad sealed contacts storehouse, and inside charges into nitrogen; Be difficult for during the heavy load break-make producing electric arc, the fixed contact both sides are provided with strong magnetic blow-out, are with energy-conservation plate; Coil temperature rise is extremely low, adopts the sealing copper pipe to adopt and colds pressing and the scolding tin dual-seal, has better seal property.
Description of drawings
Specify the utility model below in conjunction with accompanying drawing and embodiment;
Fig. 1 is the described a kind of high power DC contactor construction sketch map of the utility model.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1; Shell 4 inner tops are provided with 1, two fixed contact 1 of two fixed contacts and are arranged side by side, and epoxy resin 3 sealings are adopted in fixed contact 1 root both sides; Epoxy resin 3 tops are enclosing cover 2; Have copper pipe sealing 15 on the enclosing cover 2, promptly, then it is cut off the back sealing through inflated with nitrogen in the past seal chamber of copper pipe.The fixed contact below is a moving contact 12, and moving contact 12 can move up and down and contact fixed contact 1, and fixed contact 1 is arranged in the iron-clad cavity with moving contact 12, in the iron-clad cavity, is filled with nitrogen, can effectively prevent the generation of electric arc.Equipment integral has a shell 4, have in the shell 4 iron-clad 5 with moving contact 12, etc. in equipment puts.Epoxy resin is: RF-5407, curing agent: RF-24.
Moving contact 12 connects one 9, and axle 9 is with the below and is with moving iron core 10, is with compression spring 14 on the axle of moving contact 12 belows, and the axle of moving 10 positions unshakable in one's determination is provided with back-moving spring 11, and moving 10 arranged outside unshakable in one's determination has axle bush 8, and axle bush 8 arranged outside have coil 7.Coil 7 is wrapped in skeleton 6; In shell 4 sides one energy-conservation pcb board 13 is arranged, energy-conservation pcb board 13 is the Energy Saving Control plate, can supply with bigger starting power of coil at short notice and make its contact adhesive; Provide a less power to keep to coil then, thereby realize energy-conservation effect.
In addition, be provided with the permanent magnet that is used for magnetic quenching on the both sides of two fixed contacts 1.
Shown in Fig. 1 be the coil no power time reset condition, behind coil electricity, moving iron core 13 up move and drives moving contact and up move, and contacts with two fixed contacts 1, thereby makes the connection of two fixed contacts.Behind coil blackout, back-moving spring 11 will move iron core and press down this moment, make the disconnection of moving contact and fixed contact.
More than show and described the advantage of basic principle, principal character and the utility model of the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; The utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection range to be defined by appending claims and equivalent thereof.
