Description
Technical field
The utility model belongs to electric power project engineering field, relates to a kind of composite insulator of improvement, uses this insulator can improve the antifouling work ability of transmission line.
Background technology
Pendency arranges that insulator string is subject to the impact of creepage distance and arrangement, poor to the self-cleaning property of contamination.Especially when meeting with dense fog, drizzle or icing, the discharge voltage of these suspension insulators reduces greatly, even pollution flashover or ice sudden strain of a muscle accident occurs, has a strong impact on the safe operation of electrical network and the normal life of the people.Therefore, increase the creepage distance of insulator string or the development of obstruct electric arc of adopting an effective measure, to raising insulator contamination Power Flashover Voltage and icing Power Flashover Voltage, ensure that the safe operation of transmission line is very necessary.In actual motion, often need by increase string long, use deep bid footpath insulator instead and insulator string arranged flowers the filthy Power Flashover Voltage and icing Power Flashover Voltage that improve suspension insulator.But the old transmission line of earlier operation is comparatively conservative in design, be often subject to the restriction of tower head size and distance to the ground, the sheet number directly by increasing insulator regulates the especially aobvious difficulty of creep distance; If use deep bid footpath insulator instead by the way of some people, although then pollution flashover voltage can be improved, icing flashover voltage can not be improved; And according to the aerodynamic type insulator that diameter is greater than conventional insulators, insulator string is arranged flowers, then can intercept electric arc development, and improve pollution flashover voltage and icing flashover voltage simultaneously, but, due to aerodynamic type insulator mostly be glass material and lower surface without rib groove, often produce the problem that creepage space utilization is insufficient.
Summary of the invention
The technical problems to be solved in the utility model is, for the defect that known technology exists, there is provided a kind of composite insulator of improvement effectively to improve insulator string creepage distance, to prevent insulator umbrella edge sleet bridge joint, improve filthy Power Flashover Voltage and icing Power Flashover Voltage, thus can transform the tangent tower of existing tower head size and distance to the ground deficiency, improve transmission line power supply reliability, reduce cost of investment.
The technical solution of the utility model is, the composite insulator of above-mentioned provided this improvement, see accompanying drawing 1 ~ 2, there is a universal air power type insulator body 1 with full skirt, improvements are, the upper surface of the full skirt of described insulator body 1 is coated with one deck high-temperature silicon disulfide rubber layer 2; The bottom surface of the full skirt of this insulator body 1 is coated with one deck high-temperature silicon disulfide rubber rib layer basal plane 4, and the surface of this layer of high-temperature silicon disulfide rubber rib layer basal plane 4 is that corrugated is evenly distributed with annular prism 3.Described high-temperature silicon disulfide rubber layer 2 times edge are connected along banding enclosed along limit with edge on described high-temperature silicon disulfide rubber rib layer basal plane 4.The described thickness of high-temperature silicon disulfide rubber rib layer basal plane 4 and the thickness matching of described high-temperature silicon disulfide rubber layer 2.
Operation principle of the present utility model is: the composite insulator of described this improvement by insulator body 1 directly between be inserted on the corresponding tonnage suspension insulator of transmission line.According to line antifouling actual needs, can in advance by changing the quantity of die adjustment high-temperature silicon disulfide rubber rib layer basal plane 4 annular prism 3 and length and then changing the creepage distance of described composite insulator.The composite insulator utilizing this kind to improve is arranged flowers to common suspension insulator, when not needing change tower head and change distance to the ground, improve the creepage distance of insulator string, change its contamination and icing characteristic simultaneously, and then realize the object improving insulator string external insulation level; In addition, the composite insulator utilizing this kind to improve is arranged flowers to common suspension insulator, can effectively prevent icing insulator umbrella in season by ice slush bridge joint, improves the anti-icing ability of insulator string.
The beneficial effects of the utility model are:
1), insulator string creepage distance can be increased;
2), insulator string on transmission line can be avoided by sleet bridge joint, improve icing Power Flashover Voltage and filthy Power Flashover Voltage;
3), shaft tower window size and power transmission line corridor can be reduced, cost-saving investment.
