Description
[technical field]
The utility model belongs to electric apparatus technical field, specifically a kind of power distributing cabinet being applicable to the industrial enterprise such as power plant, transformer station, oil, chemical industry, metallurgy, machinery and skyscraper.
[background technology]
Power distributing cabinet is the visual plant of power transmission and transformation system, is applicable to the low-voltage distribution system of the industrial enterprise such as power plant, transformer station, oil, chemical industry, metallurgy, machinery and skyscraper.Distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution equipment.Due to the casing that distribution box is for laying power equipment, the heat dispersion that generally for lifting casing needs on sidewall or chamber door, arrange louvre makes gas and outside air in casing carry out exchanging the heat taken away power equipment in casing and distribute.
But the distribution box arranged like this cannot effective waterproof due to louvre, and the chamber door of distribution box is opened or is not fastened opening-wide state voluntarily by mistake, capital causes all kinds of switching device long term exposure in case in atmosphere, easily accumulates dust, enters moisture, thus affect the normal use of distribution box.
[summary of the invention]
The purpose of this utility model is to solve the not good technical problem of existing distribution box sealing, provides the low-tension distribution box that a kind of good airproof performance, water proof and dust proof effect are good.
To achieve these goals, design a kind of power distributing cabinet, comprise casing, chamber door, the upper and lower side of described casing is furnished with line square hole respectively, square hole seals plug, is furnished with mounting panel in casing, the corner of mounting panel is fixed in casing by screw-nut, mounting panel is provided with some electric elements location holes, and casing and chamber door are covered by pivot structure, and the edge ring of chamber door is wound with sealing rod.
The lower end of described sealing plug is wide at the top and narrow at the bottom horn-like, and the square hole on the lower end of sealing plug and casing is connected.
Described pivot structure comprises shaft seat, and described shaft seat is provided with shaft hole, is provided with block in shaft hole, is provided with the guide vane end stop mutually corresponding with block bottom rotating shaft.
Described casing and chamber door housing bottom are welded with earthing screw respectively.
Described chamber door is provided with operation instrument, and operation instrument is connected with the electric elements in cabinet by multiply annealed copper wire.
Compared with the existing technology, advantage is the utility model: be furnished with mounting base in casing, can install different types of electric equipment; The edge ring of chamber door is wound with the sealing rod of water-swellable, and the line square hole of the upper and lower side of casing seals plug, ensure that the sealing of power distribution cabinet, reach the effect of waterproof and dustproof, sound construction is reliable; Casing and chamber door are covered by pivot structure, and chamber door is greater than 90 degree of rotations after can opening; Casing and chamber door housing are welded with earthing screw, ensure that the effective grounding of distribution box, safe and reliable.
