Abstract
A hollow composite insulator for 363KV and 420KV switches comprises an insulating pipe, a sheath covered on the outer side of the insulating pipe and at least one umbrella skirt arranged on the outer side of the sheath. The inner diameter of the insulating pipe is 356mm to 357mm. Due to the fact that the inner diameter of the hollow composite insulator is reduced relative to an existing hollow composite insulator and experiments prove that the hollow composite insulator with the insulating pipe having the inner diameter of 356mm to 357mm can completely meet various performances required for the 363KV and 420KV switches, the material utilization amount and processing time of the hollow composite insulator are reduced, and the manufacturing cost of the hollow composite insulator is greatly reduced due to reduction of winding complexity and cutting allowance particularly.
Description
Technical field
The present invention relates to a kind of electrical circuitry equipment equipment, particularly relate to a kind of 363KV, 420KV switch hollow combined insulator that is used in the power industry High-Voltage Electrical Appliances.
Background technology
Along with the needs of the development of power industry, particularly extra-high voltage electric transmission and transformation, more and more for the demand of composite insulator.The hollow insulator of common outdoor use is generally porcelain insulator, and is of poor quality because the porcelain insulator resistant is dodged ability, easily broken in transportation and the installation process, and needs periodic cleaning in use procedure, gives to install and use has brought a lot of inconvenience.For addressing this problem, the electrical circuitry equipment industry has been developed traditional hollow combined insulator.Traditional 363KV, 420KV switch comprise an insulated tube with hollow combined insulator, a sheath that is coated on this insulated tube outside, and at least one is coated on the full skirt in this sheath outside, and the flange that is arranged on described insulated tube two ends.The insulated tube of this hollow combined insulator is by basis material, and the glass fiber yarn that is immersed in this basis material is made.This 363KV, 420KV switch with hollow insulator in order to guarantee its absolute reliability service, it is all very large that its internal diameter designs mostly, internal diameter such as the hollow insulator of present use mostly is 375 millimeters, and through the use of decades, industry thinks that mostly 375 millimeters is the standard value that 363KV, 420KV switch are used hollow insulator.But the insulated tube of hollow combined insulator generally all is to make by winding process.In winding process, what of the complexity, material usage, process time of winding process and cutting surplus the internal diameter of the insulated tube of hollow combined insulator determined.Therefore, existing hollow combined insulator with 375 millimeters can cause very large winding complexity, too much material usage and process time, and more cut surplus, thus cause the cost of hollow combined insulator to rise.
Summary of the invention
In view of this, be necessary the 363KV, the 420KV switch hollow combined insulator that provide a kind of internal diameter less.
A kind of 363KV, 420KV switch hollow combined insulator, it comprises an insulated tube, a sheath that is coated on this insulated tube outside, and at least one is arranged on the full skirt in this sheath outside.The internal diameter of described insulated tube is between 356 millimeters to 357 millimeters.
Compared with prior art, because the minimizing of the internal diameter of hollow combined insulator, and the experiment proved that, the hollow combined insulator that has internal diameter and be 356 millimeters to 357 millimeters insulated tube can meet 363KV, the desired properties of 420KV switch fully, thereby so that its material usage, all be reduced process time, particularly twines complexity and the minimizing of cutting surplus, greatly reduces the manufacturing cost of hollow combined insulator.
