Abstract
The invention relates to the technical field of circuit breakers, in particular to a vacuum circuit breaker. The vacuum circuit breaker comprises an operating mechanism, insulators and a vacuum arc extinction chamber, wherein the insulators are connected with the operating mechanism; and the two ends of the vacuum arc extinction chamber are connected with the insulators. The working state of the vacuum circuit breaker is independent of the outside atmospheric condition; the cut-off performance of the vacuum arc extinction chamber cannot be influenced by the outside and high pressure cannot be generated in the cut-off process, so explosion risk is small; high noise is not generated when short-circuit current is cut off; and the vacuum circuit breaker has high structural performance and is safe to use and easy to maintain.
Description
Technical field
The present invention relates to a kind of circuit breaker, relate in particular to a kind of vacuum circuit-breaker.
Background technology
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: sometimes 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 vacuum circuit-breaker 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 operating mechanism, insulator and vacuum interrupter, described insulator is connected with operating mechanism, and described vacuum interrupter two ends connect insulator.
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, operating mechanism, 2, insulator, 3, vacuum interrupter.
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, comprises operating mechanism 1, insulator 2 and vacuum interrupter 3 among the figure, and described insulator 2 is connected with operating mechanism 1, and described vacuum interrupter 2 two ends connect insulator 2.The structure outward appearance of vacuum interrupter 3 is just as large-scale radio tube, shell by or pottery make, bellows is leaned in sealing during the moving contact motion, operating state and ambient atmosphere conditional independence, and 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, does not also have very big noise when cut-offfing short circuit current, and this structural behaviour is good, safe in utilization, safeguard 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.
