Technical field
The invention belongs to high pressure equipment for power transmission and distribution technical field, especially relate to a kind of common box type gas insulating metal enclosed switch device of the SF6 of employing gas insulation technology.
Background technology
Common box type gas insulating metal enclosed switch device (C-GIS) is to be the switch cubicle of dielectric with SF6 gas, is widely used in the abominable especially area of the high engineering construction project of land used anxiety and reliability requirement, environment and the power station, industrial area of pollution severity.Be specially adapted to highlands (as the Qinghai-Tibet Platean), the area of coastal meteorological condition difference, filthy serious enterprise (as chemical plant, cement plant) is in the important load field of employment that can not have a power failure (as subway, tunnel).
The common box type gas insulating metal enclosed switchgear is the expansion of high pressure C-GIS product in middle pressure field.It is to adopt hypobaric SF6 gas, N2 gas or the mist dielectric as switchgear; with vacuum as arc-extinguishing medium; medium pressure elements such as bus, vacuum circuit-breaker, isolating switch are concentrated be enclosed in the casing, the modern insulation technology of integrated use, cut-off the new high-tech product that integrates Based Intelligent Control, protection, supervision, measurement, communication that technology, manufacturing technology, sensing technology, digital technology are produced.Have that volume is little, in light weight, fail safe is good, reliability is high, can adapt to and advantage such as use under the severe environmental conditions.
In the pressure field especially in the 40.5kV electric pressure, the general volume of switch cubicle of conventional with the air is dielectric is big (the wide 1200mm that is not less than of cabinet, volume generally is not less than 7 cubic metres), weight heavier (generally being not less than 2t), operating difficulties.Because the conventional air insulated switching installation is subjected to the limitation of environmental condition (as high height above sea level, humidity, salt fog, filth, corrosion etc.), can not satisfy users' such as metallurgy, petrochemical industry, mine and coastal area requirement; Occasions such as city underground and light rail, skyscraper, large enterprise because of factors such as floor space, spatial limitation, also will be selected the 35kV gas-insulated switchgear for use.
Summary of the invention
The objective of the invention is to improve the deficiency of prior art and a kind of good sealing effect, long service life, safe and reliable, common box type gas insulating metal enclosed switch device that volume is little, applied widely are provided.
The object of the present invention is achieved like this, a kind of common box type gas insulating metal enclosed switch device, be by cabinet, tri-station isolating switch, three station spring operating mechanisms, main bus bar in the main bus bar sleeve pipe, vacuum circuit-breaker, voltage transformer, cable joint, zero-sequence transformer and lightning arrester are formed, be characterized in being provided with in the cabinet the last gas tank and the following gas tank of sealing, tri-station isolating switch and main bus bar sleeve pipe and main bus bar are installed in the last gas tank, the output shaft of three station spring operating mechanisms stretches in the gas tank and is connected by the rotary seal hookup with tri-station isolating switch, vacuum circuit-breaker in tri-station isolating switch and the following gas tank joins by the busbar connection device, vacuum circuit-breaker and spring mechanism link by the metal bellows sealing mechanism, the lead that passes through of vacuum circuit-breaker connects the inner cone insulator of sealing and fixing at therapeutic method to keep the adverse qi flowing downward tank wall, and the inner cone insulator inserts voltage transformer respectively, cable joint, zero-sequence transformer and lightning arrester.
In order further to realize purpose of the present invention, can be that described rotary seal hookup is that three station spring operating mechanism output shafts are provided with outside framework oil seal with the shaft room that is fixed on the gas tank wall, be provided with sealing gasket between axle sleeve and last gas tank wall.
In order further to realize purpose of the present invention, can be that output shaft upper skeleton oil sealing is that two and direction are relative.
In order further to realize purpose of the present invention, can be that the insulated tension pole that described metal bellows sealing mechanism is a vacuum circuit-breaker is connected with the metal bellows that passes through of the connecting rod of spring mechanism, metal bellows is installed in therapeutic method to keep the adverse qi flowing downward tank wall by the mounting panel sealing, is provided with sealing ring between mounting panel and therapeutic method to keep the adverse qi flowing downward tank wall.
In order further to realize purpose of the present invention, can be on last gas tank and following gas tank, to be provided with to rush down to press door.
Compared with the prior art the present invention has following distinguishing feature and good effect: the structure that the present invention adopts has significantly reduced volume, area, volume have all reduced nearly 2/3, only more bigger or suitable than the air insulation switch cubicle of present 12kV level, the scope of application is more extensive, has following characteristics simultaneously:
1, on last gas tank and following gas tank, is provided with to rush down and presses door, during the casing operate as normal, gas pressure is 0.04MPa, when reasons such as condition of work or misoperation cause the internal arc fault, air pressure raises, and rushes down to press door to open, gas is discharged by pressure release passage, prevent that inner body from flying out and splashings injure the people, also do not influence the operation of adjacent cabinet simultaneously, guarantee the safety of operating personnel and inflation cabinet.
2, the static seal pad on upper box and the rotary seal hookup is bound up closely through after the bolted, gas was airtight when the decrement of dependence static seal pad guaranteed to go up the gas tank operate as normal, the high output shaft of surface smoothness compresses two outside framework oil seals that direction is relative in installation process, the decrement of outside framework oil seal guarantees that output shaft drives the airtight of gas tank in the seal shaft motion process.
3, the effective special equipment of wavy metal by argon arc welding with insulated tension pole and connecting rod welding forming, the sealing mechanism that makes it become end sealing and can bear relevant work air pressure, the spring mechanism of connecting rod and circuit breaker links to each other, and the metal bellows sealing mechanism is installed on the mounting panel, the decrement that relies on the static seal circle is moved the confined gas of gas tank at present to guarantee circuit breaker.
