Description
Technical field:
The utility model relates to a kind of gas-filling cabinet, is specially a kind of common box type all insulation sulfur hexafluoride gas-filled cabinet.
Background technology:
Sulfur hexafluoride gas-filled cabinet is widely used in the places such as industrial and mining enterprises, skyscraper, residential quarters, electrical network tap, small switch station, school, as the use of power distribution and terminal power distribution.Because the equipment in sulfur hexafluoride gas-filled cabinet is more, and relate to high-tension electricity, so safety measure is particularly important, in order to ensure fail safe, current sulfur hexafluoride gas-filled cabinet is arranged in gas tank by open circuit main switch, in gas tank, adopt sulphur hexafluoride as protection gas, the electric device of other band high-tension electricity is arranged in cabinet, and adopts air insulation; Air insulation has cost advantage low and easy to maintenance, but owing to containing a certain amount of salinity, dust and moisture in air, through accumulation for a long time, can the surface of electric device in cabinet formed contain salt, the dirt of dust and water, reduce insulation property, especially, when air ratio is moister, be easily short-circuited accident.
Summary of the invention:
The purpose of this utility model is to provide a kind of common box type all insulation sulfur hexafluoride gas-filled cabinet, to solve in above-mentioned air containing a certain amount of salinity, dust and moisture, through accumulation for a long time, can be formed on the surface of electric device contain salt, the dirt of dust and water, reduce insulation property, especially when air ratio is moister, the problem of the accident that is easily short-circuited.
To achieve these goals, technical solution of the present utility model is: common box type all insulation sulfur hexafluoride gas-filled cabinet, comprise cabinet and the gas tank be arranged in cabinet, low-voltage bus bar room, gas tank mechanism installing zone and cable vault, high voltage bus, on-load switch, earthed switch, open circuit main switch and isolating switch are installed in gas tank, in gas tank, are full of sulfur hexafluoride gas; Low-voltage bus bar room is positioned at the top of cabinet, and cable vault is positioned at the bottom of cabinet; Gas tank mechanism installing zone is arranged on the side of gas tank, is provided with open-circuit operation mechanism and isolated operation mechanism in gas tank mechanism installing zone.
Further, described cabinet is provided with pressure relief opening, the quantity of pressure relief opening is preferably two.
Gas tank adopts metal material manufacture, preferably adopts stainless steel material manufacture.
The utility model common box type all insulation sulfur hexafluoride gas-filled cabinet is by on-load switch, earthed switch, the electric device of the band such as open circuit main switch and isolating switch high-tension electricity is all sealed in casing, and be subject to the protection of sulfur hexafluoride gas, degree of protection reaches IP67, be arranged in gas tank relative to only having open circuit main switch in prior art, can salinity in completely isolated air, dust and moisture, make the electric device of band high-tension electricity not by the impact of external condition as much as possible, ensure that the insulating properties of gas-filling cabinet, even if when air ratio is moister, also the accident of being short-circuited is difficult to, greatly increase the reliability of gas-filling cabinet.
Insulate and arc-extinguishing medium owing to adopting the sulfur hexafluoride gas of insulation property brilliances to do, can make between combined electrical apparatus conductor, conductor over the ground between minimum electrical distance greatly reduce, so the volume of electric substation significantly can be reduced, realize miniaturized.
Gas tank adopts metal material manufacture, has good ground connection conductive effect, is all sealed in by the electric device of band high-tension electricity and has in the metal shell of good earth, the danger of thus not getting an electric shock; Sulfur hexafluoride gas is non-flammable gases, does not therefore also have fire hazard.
The adverse effect of Du's absolute external.Because live part is closed with metal shell, shielding is realized to electrostatic and electromagnetism, the problem such as noise and radio interference can not occur.
