Abstract
The invention relates to the technical field of circuit breakers, in particular to a structure of a vacuum interrupter. The structure comprises an insulation shell, an end cover, a fixed contact, a moving contact, a main shielding case, a corrugated pipe shielding case, another end cover and a corrugated pipe, wherein the insulation shell is arranged out of the end cover; the main shielding case is arranged above the end cover; the fixed contact and the moving contact are arranged in the main shielding case; and the corrugated pipe is arranged in the corrugated pipe shielding case. The working state of the structure has nothing to do with external atmospheric conditions; the breaking performance of the vacuum interrupter is free from external influence; a very high pressure cannot be generated in a breaking process, so explosive risk is low; and very high noise cannot be generated when a short-circuit current breaks. The structure has high performance and is safe to use and simple to maintain.
Description
Technical field
The present invention relates to a kind of arc control device, relate in particular to a kind of structure of vacuum interrupter.
Background technology
Vacuum interrupter is to realize the connection of power circuit and a kind of electron tube of disjunction function with sealing a pair of contact in a vacuum, is to utilize high vacuum to make dielectric.When it disconnects the electric current of certain numerical value, move, decide the moment that contact is separating, electric current is retracted on contact firm certain of separating any or some, violent increase of resistance and temperature improve rapidly between the performance motor, until the generating electrodes evaporation of metals, form high electric field strength simultaneously, cause the violent field emission and the puncture in gap, produce vacuum arc.
The many new technologies that grow up along with electronics industry, the a lot of difficulties during vacuum interrupter is made have been solved, be that switch progressively reaches realistic scale, but sometimes owing to be subjected to the restriction of technical merits such as vacuum technology, material, in use because structural reason adds out that distance is little, arc voltage is low, and arc energy is little, and surperficial scaling loss can appear in contact surface when cut-offfing.
Summary of the invention
The technical problem to be solved in the present invention is: owing to be subjected to the restriction of technical merits such as vacuum technology, material, in use because structural reason adds out that arc voltage is low apart from little, arc energy is little, surperficial scaling loss can appear in contact surface when cut-offfing, and a kind of structure of vacuum interrupter is provided.
In order to overcome the defective that exists in the background technology, the technical solution adopted for the present invention to solve the technical problems is: the present invention includes insulation crust, end cap, fixed contact, moving contact, main shield cover, bellows shield cover, end cap and bellows, described end cap is provided with insulation crust outward, the top of end cap is provided with the main shield cover, in the main shield cover, be provided with fixed contact and moving contact, be provided with bellows in the described bellows shield cover.
The invention has the beneficial effects as follows: operating state of the present invention and ambient atmosphere conditional independence, the vacuum interrupter break performance can not be subjected to externalities, can not produce very high pressure in the interrupting process, explosion hazard is little, there is not very big noise when cut-offfing short circuit current yet, this structural behaviour is good, and is safe in utilization, safeguards simple.
Description of drawings
The present invention is further described below in conjunction with drawings and Examples.
Fig. 1 is a structural representation of the present invention;
Wherein: 1, insulation crust, 2, end cap, 3, fixed contact, 4, moving contact, 5, the main shield cover, 6, the bellows shield cover, 7, end cap, 8, bellows.
Embodiment
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, basic structure of the present invention only is described in a schematic way, so it only show the formation relevant with the present invention.
Fig. 1 is a structural representation of the present invention, comprise insulation crust 1, end cap 2, fixed contact 3, moving contact 4, main shield cover 5, bellows shield cover 6, end cap 7 and bellows 8 among the figure, the described end cap 2 outer insulation crusts 1 that are provided with, the top of end cap 2 is provided with main shield cover 5, in main shield cover 5, be provided with fixed contact 3 and moving contact 4, be provided with bellows 8 in the described bellows shield cover 6.When radome can make the alternating current zero passage, remaining metallic vapour and conducting particles radially were diffused on the radome apace in the arc control device, and cooling, compound and condense helps the raising of arc gap dielectric strength behind the current over-zero, has improved the break performance of arc control device.The design of radome helps improving dielectric strength between contact.Bellows can guarantee the sealing fully of vacuum extinction chamber enclosure when the moving contact reciprocating motion.
This structural behaviour is good, and is safe in utilization, safeguards simple.
With above-mentioned foundation desirable embodiment of the present invention is enlightenment, and by above-mentioned description, the related work personnel can carry out various change and modification fully in the scope that does not depart from this invention technological thought.The technical scope of this invention is not limited to the content on the specification, must determine its technical scope according to the claim scope.
