Abstract
The invention discloses a processing technology for a pin shaft, and particularly discloses a manufacturing method for an insulating pull rod used for a 800kV circuit breaker. The manufacturing method for the insulating pull rod used for the 800kV circuit breaker comprises the following steps that a cloth blank of glass fiber cloth is manufactured via winding-preheating vacuum-pumping processing is performed-pressure gumming is performed. According to the manufacturing method for the insulating pull rod used for the 800kV circuit breaker, capacity of the product for bearing overvoltage is enhanced, production cost is reduced, material supply period is shortened, air blow effect of high-temperature air flow can be borne and arc decomposition corrosion can be resisted so that various problems caused by use of import pieces are eliminated.
Description
Technical field
The present invention relates to a kind of production method of 800kV insulated pull rod for circuit breaker.
Background technology
Along with China's power system technology is constantly progressive, Ge great High-Voltage Electrical Appliances manufacturing company research and development strength constantly strengthens, high-voltage switch gear structure is more reasonable, performance is more reliable, and China has had enough strength to carry out research and development and the production of superhigh pressure and ultra high voltage High-Voltage Electrical Appliances, and, along with national economic strength strengthens, the continuous enforcement of great national construction project and development of the West Regions, the demand of high voltage switchgear is also increased day by day, electric pressure is progressively by 330kV, 550kV goes forward one by one to 800kV and 1000kV, Northwest Grid was also carried out Technological Economy comparison to 550kV and two schemes of 800kV, result shows that 800kV gross investment and annual cost are all than the obvious minimizing of 550kV, and 800kV voltage carries electricity to improve electric power fed distance and transmission capacity, reduced transmission losses, in high voltage switchgear, take circuit breaker as representative, its arc quenching principle, relate to aerodynamics, machine driving, the multi-disciplinary knowledge such as High-Voltage Insulation, circuit breaker be take arc control device as core component, in primary cut-out, only containing arc control device, be called single-break circuit breaker, containing two arc control device, be called double-fracture circuit breaker, in primary cut-out, insulated tension pole plays gearing, need insulated tension pole to there is good electrical insulation properties and tension mechanical performance and good arc resistance energy, therefore insulated tension pole is as the main parts size in circuit breaker, for the serviceability of whole circuit breaker and useful life aspect play vital effect.
At present, the external imported product of the most of employing of insulated tension pole that high-voltage switch gear adopts, adopts integral body to roll, then surface spraying insulating varnish, from result of use, import pull bar inside exists that resin mixed material and fortifying fibre infiltrate thoroughly, have the phenomenons such as microbubble between fortifying fibre.These defects directly affect electrical insulation properties and the mechanical performance of insulated tension pole, have a strong impact on the performance of circuit breaker, and bring huge difficulty to production, and in addition, Imported Insulation pull bar production cost is high, and delivery cycle is long, and difficult solution that go wrong.
summary of the invention
The invention provides a kind of production method of 800kV insulated pull rod for circuit breaker, reach and improved product and bear superpotential ability, reduced production cost, and shortened the object of delivery cycle.
The technical scheme that the present invention addresses the above problem, comprises following steps: coiling glass fabric cloth base---preheating vacuumizes processing---pressure impregnation.
The present invention compared with prior art has the following advantages:
(1) improve product and born superpotential ability;
(2) reduce production cost, and shortened delivery cycle;
(3) can bear the performance of the air-blowing effect of high temperature gas flow and the analyte of resistance to electric arc corrosion;
(4) broken away from the variety of issue that uses import parts to bring.
Embodiment
Below provide specific embodiments of the invention, be used for formation of the present invention to be further described.
A kind of embodiment that the invention provides a kind of production method of 800kV insulated pull rod for circuit breaker, comprises the following steps:
1) coiling glass fabric cloth base, cloth base is comprised of woven dacron and glass fabric, and in cloth base, the ratio of woven dacron and glass fabric is 1.6:11, and woven dacron plays cover glass fiber cloth and is not subject to SF
6the effect of analyte corrosion;
2) preheating vacuumizes that to process be by the air in cloth base, moisture removal, guarantees that cloth base is dry, gets rid of the air in cloth base, guarantees the electrical insulation properties of insulated tension pole;
3) pressure impregnation is that the compound of epoxy resin and curing agent is injected in cloth base under pressure, by cloth base complete wetting, by the intensification in later stage, solidify cloth base is bonded together, resin mixture, glass fabric are merged and be called integral body, make insulated tension pole there is higher mechanical performance.
