Abstract
The utility model discloses a dustproof gap-discharging-resistant contact box for a switch cabinet, comprising a hollow box body. A wire inlet is arranged in the lower end of the box body, and a wire outlet is arranged in the upper end of a sidewall of the box body; soleplates extending outwardly are arranged along outer walls in the lower end of the box body, wherein the lower surface of each soleplate is positioned over the plane of the wire inlet; a rectangular frame protruding outwardly is arranged along the wire outlet outside the box body; a cap is arranged in the top of the box body, wherein an embedded piece and a shielding ring are arranged on the cap; insulating shed groups are respectively arranged on the inner and outer walls of the box body; and dustproof rubber rings closed inwardly are respectively arranged in the wire inlet and in the rectangular frame outside the wire outlet. The dustproof gap-discharging-resistant contact box for the switch cabinet is simple in structure, can effectively prevent fine foreign materials as dusts from entering into the contact box, ensures the internal of the contact box is clean and dust-free, effectively reduces the possibility of corona discharging phenomena, effectively eliminates discharging phenomena in air gaps, improves the safety performance of the contact box, and guarantees safe use of the switch cabinet.
Description
Technical field
The utility model relates to a kind of parts of switch cubicle, is specially a kind of switch cubicle with preventing dust, prevent the gap discharge contact box.
Background technology
Contact box is one of important spare part in switch cubicle, is used for various handcart switch cabinets, plays the insulation isolation and connects transitional function.Yet existing contact box in use, because operational environment is stable not, the tiny foreign material such as dust easily have into and out of the line mouth and enter contact box, and then cause being stained with dust on contact box inwall and inner member, make the corona discharge phenomenon more easily occur, can cause that insulating part punctures, explodes when serious, and that end that nut is positioned at the mount pad lower surface adopts the insulating material shutoff, but still can have the air gap, and can discharge by the air gap, make switch cubicle have potential safety hazard.
The utility model content
The purpose of this utility model is to provide a kind of switch cubicle with preventing dust, prevent the gap discharge contact box, to solve contact box traditional in prior art in use, the tiny foreign material such as dust easily have into and out of the line mouth and enter contact box, and then cause being stained with dust on contact box inwall and inner member, make the corona discharge phenomenon more easily occur, and there is the air gap in the mount pad lower surface, and the gap discharge phenomenon easily occurs, and makes switch cubicle have the problem of potential safety hazard.
For achieving the above object, the technical solution adopted in the utility model is:
a kind of switch cubicle is with dustproof, anti-gap discharge contact box, it is characterized in that: include hollow box, described box body lower end is provided with incoming line, the upper end sidewall is provided with line outlet, described box body lower end edge outer wall is provided with the mount pad of outside extension, the lower surface of described mount pad is positioned at the top on plane, incoming line place, the described box body outside is provided with outwardly rectangle frame along line outlet, described box body top is provided with capping, described capping is provided with inserts and shading ring, in described box body, outer wall is respectively equipped with the insulation cluster parachute, be respectively equipped with the wiper of rubber of inside closing in rectangle frame outside described incoming line and line outlet.
Described a kind of switch cubicle is with preventing dust, preventing the gap discharge contact box, and it is characterized in that: described mount pad is provided with several installing holes.
Described a kind of switch cubicle is with preventing dust, preventing the gap discharge contact box, and it is characterized in that: described capping and mount pad are all one-body molded with box body.
The beneficial effects of the utility model are:
The utility model is simple in structure, and is easy for installation, good insulation preformance, employing is arranging the design of wiper of rubber into and out of the line mouth, prevented that effectively the tiny foreign material such as dust from entering in contact box, guaranteed that in contact box, cleaning is dustless, effectively reduced the probability of happening of corona discharge phenomenon; The lower surface of mount pad is directly sealed nut by insulating material, has eliminated the air gap electric discharge phenomena, has promoted the security performance of contact box, has ensured the use safety of switch cubicle.
