Description
Technical field
The utility model relates to a kind of ring main unit, more particularly, relates in particular to a kind of all insulation inflation ring main unit.
Background technology
In the high pressure ring cabinet, SF6 (sulphur hexafluoride) inflation ring main unit has received the favor in market with its reliable work performance, has obtained very big development.But at present from the domestic nearly product of last hundred families, the ubiquity airtight performance is poor, working life is lacked, not easy care, many-sided problem such as floor space is big, automatization level is low, has seriously restricted the application and the development of China's ring main unit.The problems that just exist owing to China's like product, it is slower that this series products is promoted at home.But in developed countries such as America and Europes, the ring main unit high cost performance makes product obtain to use widely, has obtained good economic benefit and social benefit.
At present, most domestic market is captured by foreign capitals manufacturers such as ABB, Siemens basically, though domestic industries manufacturer is a lot, because the problem of technology and fund, the quality of product faces very big defective.Along with the level of the science and technology of China in recent years with personnel training constantly promotes, the continuous accumulation of the operating experience of domestic electrical network, homemade gas-filled switching tube certainly will will substitute the product of import.
In addition; Along with the Chinese society rapid economic development, the continuous propelling of the city net upgrading of rural power grids, the city is also improving constantly for the requirement of electric power network technique; Overall security, the intelligent level of urban distribution network are significantly improved; How to reduce the volume of power equipment as much as possible,, become the important topic that contemporary China's power equipment development faces progressively to miniaturization, intelligent development.Particularly more abominable in more regional external environment, maintenance cost is high, under the situation of maintenance difficulties, improves the useful life of controller switching equipment, or even to reach non-maintaining purpose be the target that numerous production firms put forth effort to pursue.
The utility model content
The purpose of the utility model is the deficiency to above-mentioned prior art, and a kind of compact conformation, all insulation inflation ring main unit that insulation effect is good are provided.
The technical scheme of the utility model is achieved in that a kind of all insulation inflation ring main unit, comprises cabinet, is provided with the insulation sealed chamber in the wherein said cabinet, in the insulation sealed chamber, is provided with the switch module, and the switch module is connected with operating mechanism; Also be provided with the output cable chamber at cabinet; The power input of switch module is connected with the external power source circuit; The power output end of switch module is connected with the power input circuit of the indoor output cable of output cable, and the power output end of output cable is connected with the external electric equipment circuit.
In the above-mentioned all insulation inflation ring main unit, described switch module is made up of combination switch, earthed switch and insulation connecting axle, and described combination switch and earthed switch are oppositely arranged, and described insulation connecting axle is arranged between combination switch and the earthed switch; Described operating mechanism and the interlock of insulation connecting axle.
In the above-mentioned all insulation inflation ring main unit, also be provided with fuse on the circuit between described switch module and the output cable chamber.
In the above-mentioned all insulation inflation ring main unit, described insulation sealed chamber also pipeline is connected with the pressure release room.
In the above-mentioned all insulation inflation ring main unit, also be provided with rupture pressure disc between described insulation sealed chamber and the pressure release room, described rupture pressure disc is arranged on the inwall of pressure release room.
After the utility model adopted said structure, through with live part, the switch module that promptly is connected with external power source was arranged in the sealed chamber that insulate; And in the insulation sealed chamber, fill SF6 gas; Sulfur hexafluoride gas has good physicochemical property, arc extinguishing insulation property, and dielectric strength is 2.5 times of air, and the dielectric strength when 0.29 MPa pressure is just close with transformer oil; And there is not the problem of oxidation at positions such as contact in oxygen-free gas in the sulfur hexafluoride gas; Even the blocking under big electric current of the contact of sulphur hexafluoride equipment, its wearing and tearing are also few, make that the live part in the whole cabinet is all mended isolation, improve security performance; Simultaneously through the pressure release room is set, make to occur unusual and when making air pressure in the insulation sealed chamber when the switch module above certain numerical value, can pressure release room release from the bottom, effectively prevent the infringement of gases at high pressure to all the other equipment in people, cable and the transformer station.
