Description
Technical field
The utility model relates to a kind of lightning arrester, specifically a kind of composite insulating metal oxide lightning arrester.
Background technology
The composite insulating metal oxide lightning arrester purposes: the effect of lightning arrester is over-voltage with the protection electric equipment, both can be used to protect atmospheric over-voltage, also can be used to the fence operation overvoltage.Lightning arrester is connected between wire and the ground usually, and is in parallel with protected equipment, when protected equipment moves under normal voltage; Analyse of Reject-acting Arrester namely is considered as opening circuit, in case overvoltage occurs over the ground; and crisis is protected when apparatus insulated; lightning arrester moves immediately, with high-voltage impact conduct current the earth, thus the deboost amplitude; the insulation of protection electric equipment; after having served as loss of voltage, lightning arrester immediate recovery high-impedance state can normally be moved electric power system.
Domestic lightning arrester is divided into by the external insulation mode at present: porcelain bushing type lightning arrestor and composite insulating lightning-protection device.
The above product of porcelain bushing type lightning arrestor structure: rated voltage 42KV is comprised of unit of an arrester top cover, base.Zinc oxide valve plate is equipped with in unit of an arrester inside, valve block is fixed with 4 pull bars, the spring compression unit of an arrester, with pressure relief device, when lightning arrester damaged under above given load or fortuitous event, its internal pressure rose rapidly, when pressure reaches a certain set point, the explosion-protection equipment action, Exhaust Gas prevents the insulator blast.During installation, at first fixing lightning arrester base, other elements are installed from bottom to top, and require the deviation between element center and the vertical line to be not more than 2% of element heights.Bolt on the top cover is connected with high-pressure side, and the bolt on the insulator foot can be connected with the discharge counter high-pressure side, by discharge counter earth terminal ground connection.If without the direct ground connection of discharge counter.
The composite insulating lightning-protection device of present domestic other lightning arrester manufacturer production: mostly adopt the epoxy resin bushing encapsulation, take the TBE (threaded both ends) electrode on the structure, inside adds spring resistor disc is fixed, the outside adopts split type silica gel full skirt to do external insulation again, mechanical strength and the seal request of lightning arrester can not be guaranteed, the mode that adopts glass fiber and epoxy resin to twine is also arranged, intensity has been strengthened, production cycle has also lengthened, the lightning arrester core body of a 220kV is from being wound into curing, want continuous more than the 20 hours time just can finish, the whole production cycle needs 4-5 days.Even the intensity of the product of 220kV also is difficult to reach specification requirement like this.
The utility model content
The purpose of this utility model provides a kind of composite insulating metal oxide lightning arrester, and this lightning arrester volume is little, lightweight, durability against pollution is strong, and explosion-proof performance is good.
The technical scheme that adopts is:
A kind of composite insulating metal oxide lightning arrester comprises lightning arrester core body, floor installation flange, high-voltage connection terminal and ground wire binding post, it is characterized in that:
Described lightning arrester core body comprises bottom electrode, cross-over block, conducting block, resistance bolck and top electrode; Resistance bolck is made of a plurality of resistor disc closed assemblies; Bottom electrode, collets, conducting block, resistance bolck and top electrode are vertically used without the latitude band behind the closed assembly successively and are fastened, and adopt that mould is disposable to be encapsulated in the first insulating barrier that is made of the SMC material, outside the first insulating barrier, adopt sulfidization molding of mould that king-post shape silicon rubber the second insulating barrier is arranged; Bag is provided with in the groove of lower end inserted base mounting flange of lightning arrester core body of the first insulating barrier and the second insulating barrier, and is fixedly connected with lightning arrester core body by screw; In the binding post preformed hole of conducting block, be equiped with the ground wire binding post, in the binding post preformed hole of top electrode, be equiped with the high-voltage line binding post.
Described resistor disc is the metal oxide varistors sheet, and described is unsaturated polyyester impregnated glass fiber binding strap or other high-strength insulating material bands without the latitude band.
The utility model is to become lightning arrester core body by metal oxide varistors sheet closed assembly, the closed assembly of chip adopts and is fastened without latitude band macromolecular material, adopt the macromolecular material special process that the disposable sealing pressing of core body is formed in the High Performance Insulation material after solidifying, take at last a pressing process that it is sealed in the silicon rubber body, form whole lightning arrester, realize positiver sealing, the approach that does not have moisture to invade.
Adopt that the production cycle of lightning arrester can shorten greatly after this kind technique, 35KV, 66KV, 110KV, 220KV, 500KV production cycle can be reduced to 1/4 of other techniques.
The utility model has the advantage of:
The wet lightning pressure of external insulation is high, durability against pollution is strong.External insulation adopts the methyl vinyl silicone rubber material, and electrocorrosion-resisting, anti-aging, overcoat are by 6 grades of galvanic corrosion, and the 1000h salt mist test, and silastic material has hydrophobicity and migration of hydrophobicity, and durability against pollution is strong.
Has good explosion-proof performance.When lightning arrester seriously transships, owing to adopt the real cored structure of compound inslation, do not have generation and the expansion of gas, composite insulation outer coat can delay again impulsive force and avoid blast, has stopped to involve after porcelain bushing type lightning arrestor explodes the generation of the serious accident of peripheral equipment and personal safety.
Can be smoothly by boiling 42 hours test in 0.1% the NaCl aqueous solution, electrical property is constant.Owing to fundamentally solved sealing problem, product need not to do preventive trial every year.
Volume is little, and is lightweight.Owing to adopt the sealing means of compound inslation, greatly reduced volume and the weight of lightning arrester, mounting means is (upright, suspension, inclination etc.) flexibly, also can doublely do supporting insulator and use.
