Abstract
The invention relates to an improved composite insulator. The improved composite insulator comprises an insulator body (1) with an umbrella skirt. The upper surface of the umbrella skirt is covered with a high-temperature vulcanization silicone rubber layer (2); the lower surface of the umbrella skirt is covered with a high-temperature vulcanization silicone rubber edge layer base surface (4), and annular prisms (3) are distributed on the surface of the high-temperature vulcanization silicone rubber edge layer base surface (4). The lower edge of the high-temperature vulcanization silicone rubber layer (2) is connected with the upper edge of the high-temperature vulcanization silicone rubber edge layer base surface (4). The thickness of the high-temperature vulcanization silicone rubber edge layer base surface (4) is matched with that of the high-temperature vulcanization silicone rubber layer (2). The composite insulator has the advantages that the creepage distance of an insulator chain can be increased; the insulator chain on an electric transmission line can be prevented from being in bridging connection by icicles, and the icing power frequency flashover voltage and the dirty power frequency flashover voltage can be improved; the window size of a pole and tower can be reduced, a corridor of the pole and tower can be shrunk, and the cost is saved.
Description
Technical field
The invention belongs to electric power project engineering field, relate to a kind of improved composite insulator, use this insulator can improve the anti-pollution flashover ability of transmission line.
Background technology
Dangle and arrange 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, and pollution flashover or ice sudden strain of a muscle accident even occur, and has a strong impact on the safe operation of electrical network and the people's normal life.Therefore, increase the creepage distance of insulator string or the development of the obstruct electric arc of adopting an effective measure, to improving insulator contamination Power Flashover Voltage and icing Power Flashover Voltage, guarantee that the safe operation of transmission line is very necessary.In actual motion, often need filthy Power Flashover Voltage and the icing Power Flashover Voltage of by increase, going here and there length, using large disk track insulator instead and insulator string is arranged flowers to improve suspension insulator.Yet the old transmission line putting into operation is in early days comparatively conservative in design, is often subject to the restriction of tower head size and distance to the ground, directly by increasing the sheet number of insulator, regulate the especially aobvious difficulty of creep distance; If use large disk track insulator instead by the way of some people, although can improve pollution flashover voltage, can not improve ice lightning and press; And if the aerodynamic type insulator that adopts diameter to be greater than conventional insulator is arranged flowers to insulator string, can intercept electric arc development, and improve pollution flashover voltage and ice lightning simultaneously and press, but, because aerodynamic type insulator mostly is glass material and lower surface without rib groove, often produce the inadequate problem of creepage space utilization.
Summary of the invention
The technical problem to be solved in the present invention is, the defect existing for known technology, provide a kind of improved composite insulator 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, thereby 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.
Technical scheme of the present invention is, above-mentioned provided this improved composite insulator, referring to accompanying drawing 1～2, there is one with the universal air power type insulator body 1 of 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 corrugated and is evenly distributed with annular prism 3.2 times edge of described high-temperature silicon disulfide rubber layer are connected along banding enclosed with edge on described high-temperature silicon disulfide rubber rib layer basal plane 4 along limit.The thickness of described 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 invention is: between described this improved composite insulator is direct by insulator body 1, be inserted on the corresponding tonnage suspension insulator of transmission line.According to line antifouling actual needs, can be in advance by changing the quantity of die adjustment high-temperature silicon disulfide rubber rib layer basal plane 4 annular prisms 3 and length and then changing the creepage distance of described composite insulator.Utilize this kind of improved composite insulator to arrange flowers to common suspension insulator, in the situation that not needing change tower head and change distance to the ground, the creepage distance that improves insulator string changes its contamination and icing characteristic simultaneously, and then realizes the object that improves insulator string external insulation level; In addition, utilize this kind of improved composite insulator to arrange flowers to common suspension insulator, can effectively prevent that icing insulator umbrella in season is by ice slush bridge joint, improve the anti-icing ability of insulator string.
The invention has the beneficial effects as follows:
1), can increase insulator string creepage distance;
2), can avoid insulator string on transmission line by sleet bridge joint, improve icing Power Flashover Voltage and filthy Power Flashover Voltage;
3), can dwindle shaft tower window size and power transmission line corridor, cost-saving investment.
