Abstract
The utility model relates to a combined dirt-proof insulator. A thermal shrinking and climb increasing apron is made into by adopting rubber plastic materials through the processing of irradiation crosslinking, dilatation, etc., and is sheathed, heated, shrunk and glued on the insulator, and the combined insulation structure of the insulator-thermal shrinking and climb increasing apron is formed. The pollution flashover characteristic of the insulator is improved, and the pollution resistance level of electric power transmission and distribution equipment is enhanced.
Description
The utility model relates to the power transmission and transformation insulator.
Power transmission and transformation insulation insulator such as rod insulator, various sleeve pipes etc. are whole porcelain spare, and inconvenience is transformed increases creep distance.Because industrial filth is on the rise, porcelain insulating creep distance deficiency causes pollution flashover accident increasing.The current anti-pollution measure of generally taking has cleaning, be coated with silicone oil (fat), change methods such as former insulator with anti-pollution type insulator, but its deficiency is arranged all.As it is big to clean the measure workload, and labour intensity height, equipment increase with shortage of manpower and some equipment and can't have a power failure, and adopts the method can not meet the demands; It is big regularly to be coated with silicone oil (fat) workload, and the term of validity is short, will be coated with once in filthy serious regional 3-6 month, and it is serious not to be suitable for depositing dust, the filthy area of granule dust; It is big to change the anti-pollution type insulator investment, and source of goods shortage is long in time limit.
For the insulator of creep distance deficiency in service being sought simple, the permanently effective anti-pollution measure of a kind of method, the utility model patent has been proposed.
The utility model is realized as follows, select for use to have excellent anti tracking performance, the rubber-plastics material of weather-resistant and surperficial hydrophobicity is processed into the heavy caliber that can be sleeved on the insulator, big disk track pyrocondensation creeping-increasing skirt such as accompanying drawing 1 through radiation crosslinking, expansion etc.The skirt inwall scribbles adhesive, makes the pyrocondensation creeping-increasing skirt can be bonded in formation combined insulation pollution proof insulator on the insulator after the heat shrink securely.
But pyrocondensation creeping-increasing skirt also suit and heat shrink is bonded in the power transmission and transformation insulation with on the sleeve pipe, to improve its antifouling property.

Characteristics of the present utility model are: the pyrocondensation creeping-increasing skirt has strengthened the creep age distance of insulator, has blocked the insulator surface leakage current, and the leakage current of combined insulation structure is obviously reduced; Installing the pyrocondensation creeping-increasing skirt near the upper and lower flange of insulator additional has the effect of obvious resistance arc, thereby the pollution flashover voltage of combined insulation structure is obviously improved, and has improved the antifouling ability of equipment. The on-the-spot suit of pyrocondensation creeping-increasing skirt easy construction uses flexibly, can determine to install skirt number, position, shape to obtain optimum efficiency according to on-the-spot gradation for surface pollution, character. After installing the pyrocondensation creeping-increasing skirt on insulator or the sleeve pipe additional the original equipment structure be need not any change. Pyrocondensation creeping-increasing skirt effective storage life is long, and service life is about more than 15 years.
The utility model embodiment is with reference to accompanying drawing 2.2(a) be transformer station's plain edition rod insulator, 2(b) after installing two pyrocondensation creeping-increasing skirts additional, constitute the combined insulation pollution proof insulator.Pyrocondensation creeping-increasing skirt installation method is simple and reliable.At first insulator is carried out preheating, when reaching 120 ℃-130 ℃, the porcelain surface temperature is inserted in the pyrocondensation creeping-increasing skirt, row heating again, creeping-increasing skirt can shrink voluntarily, adhesive fusion simultaneously, under the convergent force effect, creeping-increasing skirt is bonded on the insulator securely, forms insulator-pyrocondensation creeping-increasing skirt combined insulation structure.
