Abstract
The utility model discloses a metal sealed switch cabinet including a cabinet body, in which a plurality of electric components are arranged. The utility model is characterized in that a gap eliminating layer is arranged on the contact surface of two electric components which have spark discharge due to the potential difference caused by the fact that the electric components in the cabinet body are not intimately contacted with each other while the electric components are asked to be contacted with each other. The utility model has the advantages that the structure is simple and the usage is convenient, and the metal sealed switch cabinet eliminates air gaps, avoids the discharge phenomenon, and prolongs the service life of the electric equipment.
Description
(1), affiliated technical field
The utility model relates to a kind of Electric Appliance Cabinet, particularly 10KV metallic seal switch cubicle.
(2), technical background
Existing metallic seal switch cubicle, be provided with many electric equipment elements in the cabinet, they have a common characteristic: because metal or insulating material surface in the electric elements are not definitely smooth, cause, between metal material and the insulating material (being organic insulating material mostly), closely do not contact between insulating material and the insulating material, so exist air gap between the two.These air gap become the part of insulation system, can regard the series circuit of insulating material and air gap as, and the disruptive field intensity of air gap are lower.Under the operating voltage that remains unchanged for a long period of time, because the deterioration of insulator itself and the influence that raise by dust, airborne moisture, temperature, its insulation resistance can descend, the voltage that air gap is got will increase, when being increased to certain degree, air gap can be discharged, and discharge makes the further deterioration of insulation property of insulating material, so vicious circle, but damage equipment causes the accident.
(3), summary of the invention
The purpose of this utility model just provides a kind of metallic seal switch cubicle simple in structure, easy to use, and it has eliminated air gap, has avoided the generation of electric discharge phenomena and damage equipment, has prolonged the useful life of electric equipment.
The purpose of this utility model is to realize by such technical scheme, it includes cabinet, be provided with many electric elements in the cabinet, it is characterized in that: in the electric elements in cabinet, on the contact-making surface of two electric elements that should cause sparkover, be provided with the slit eliminating layer but tight contact forms potential difference.
The slit eliminating layer has been eliminated the air gap of two electric elements contact-making surfaces with the air gap complete filling shutoff of the contact-making surface of contacted two electric elements each other, has avoided electric discharge phenomena, has prolonged the useful life of electric equipment.Wherein said slit eliminating layer can be that the semiconductor mud material is made, and this semiconductor mud is the commercially available prod, because semiconductor mud has certain conductivity, after it is filled into air gap, makes the closely purpose of contact of two kinds of materials thereby reached.Cram with semiconductor mud and can effectively improve the Electric Field Distribution of distinct device in the junction, improve its discharge voltage, stop the further deterioration of insulation, the shape of semiconductor mud can arbitrarily change, and can fine it be packed in the air gap.Electric elements can be to wear cabinet type sleeve pipe, vacuum circuit-breaker etc., and semiconductor mud can be filled shutoff between metal material and the insulator, between insulating material and the insulating material, between metal material and the metal material.As wear between cabinet type sleeve pipe and the cabinet iron plate, between the channel-section steel between fixed contact box and the connecting copper bar, between fixed contact box and the cabinet iron plate, in post insulator and the switch cubicle.
The slit eliminating layer can also be other and the other materials that semiconductor mud has identical function, and semiconductor mud of the present utility model is the indefiniteness explanation.
Owing to adopted technique scheme, the utlity model has advantage simple in structure, easy to use, it has eliminated air gap, avoids electric discharge phenomena, has prolonged the useful life of electric equipment.
