Description
Technical field
The utility model belongs to the pollution proof insulator technical field, particularly a kind of large distance pollution proof insulator.
Background technology
At present, along with developing rapidly of power industry, the raising of transmission voltage, for the insulator of high-tension line, short along face leakage distance that is creepage distance, leakage current is big, the electric energy loss height, antifouling property is poor, easily causes the power supply obstacle.The aggravation of environmental pollution in addition, the user has higher requirement to the anti-fouling flashover performance of insulator.Traditional method is by improving the creepage distance that umbrella sheet quantity obtains to suit, umbrella shape design commonly used at present is isometrical umbrella and big umbellule, big umbellule is every a gamp umbellule to be set, above-mentioned umbrella shape can only satisfy the use of general IA, area for severe contamination, the regional required high creep distance of high height above sea level is difficult to accomplish, also have by increasing umbrella sheet diameter and adding gamp sheet consumption and improve creep distance, but its effect is unsatisfactory, because, the structure height of organic composite insulator is certain, umbrella sheet quantity increase the pitch smaller that must cause the umbrella sheet, pitch smaller can cause the self-cleaning action of umbrella sheet to be dwindled, when heavy rain comes, rainwater bridge joint umbrella spacing, and then insulator rain sudden strain of a muscle accident takes place.Therefore being necessary to design other approach increases the insulator creep distance and seems very outstanding.CN 201788771 U disclose a kind of large distance organic composite insulator, it contains plug, gamp sheet and umbellule sheet, described gamp sheet and umbellule sheet are set with and are fixed on the described plug, and, be provided with three umbellule sheets at least between the adjacent described gamp sheet.Described large distance organic composite insulator has strengthened the distance between the gamp sheet, can prevent the generation of problem such as rainwater bridge joint flashover between icing, umbrella to a certain extent, but further improve because distance is difficult between the single umbrella sheet, in order to increase creep distance, need a lot of umbrella sheets, cost of manufacture is higher, and between the umbrella sheet junction occur easily connecting unreliable.
The utility model content
The utility model purpose is to solve the problem that the insulator creep distance is short, leakage current causes existing potential safety hazard greatly, provides a kind of along big, the safe and reliable large distance pollution proof insulator of face leakage distance.
To achieve these goals, the technical solution adopted in the utility model is: a kind of large distance pollution proof insulator, it comprises insulator body, described insulator body is provided with the different insulator unit of full skirt diameter, adjacent described major diameter insulator is provided with two minor diameter insulator unit between the unit at least, the full skirt below of described insulator unit arranges cannelure, and described insulator arranges ring between the unit.
Described insulator cell surface is coated with antifouling paint.
The utility model is by arranging the different insulator unit of full skirt diameter, the full skirt below of described insulator unit arranges cannelure, can obtain very big creepage distance, satisfy the instructions for use in high pollution area, described ring is set, can not cause self-cleaning action to reduce owing to shortening the insulator unit interval, insulator rain sudden strain of a muscle accident takes place in the time of can effectively avoiding heavy rain; Adjacent described major diameter insulator is provided with two minor diameter insulator unit between the unit at least, described minor diameter insulator element diameter also can be set to different, under the prerequisite of identical creepage distance, small one and large one interval umbrella sheet that its ratio of material dosage is traditional will lack, and reduces manufacturing cost and use cost; Described insulator cell surface arranges the antifouling paint layer, has reduced the line electrical leakage loss, and the insulating ceramic surface is not subjected to dirty, can greatly reduce the pollution flashover accident rate.The utility model can realize reducing leakage current and electric energy loss by improving the creep distance of insulator, improves antifouling property, comprehensively improves the insulator dirt-proof ability, reduces rate of failure in the use, improves security performance, will produce huge economic benefit.The utility model is simple in structure, and is safe and practical, is worth of widely use.
