Abstract
The utility model relates to an organic compound sleeve spaceless metallic oxide lightning arrester used on electric locomotives, which is composed of an organic compound sleeve which is formed by the fixed connection of a silicone rubber sleeve and a lining support tube, a zinc oxide resistor chip core, and a dynamical fastening antivibration disc seat. An old technology of inflating protective gas into the cavity between the sleeve and the core is improved, insulative heat-conducting materials are injected through a vacuum injection, and a full sealing solid insulation structure is adopted. The upper and the lower two disc seats adopt a dynamic sealing fastening structure. The utility model has the advantages of light weight, good insulation performance, high mechanical strength, dirt resistance, strong antivibration ability, safety, and explosion prevention, and is suitable for the installation on the top of a vehicle. The utility model can meet the quasi high-speed requirement of electric traction, and can be used in various environmental conditions.
Description
The organic composite sheath gapless metal-oxide lighting arrester of the utility model relates to the electrical locomotive overvoltage protective device, belongs to lightning arrester.
At present, China's electric railway traction electrical locomotive overvoltage protective device has two types: a kind of is the net side 110mm rod-excellent discharging gap of locomotive main transformer; Another kind is a porcelain overcoat zero-clearance zinc oxide lightning arrester.
Porcelain overcoat zero-clearance zinc oxide lightning arrester, select for use zinc oxide resistance sheet to be assembled into lightning arrester as the valve block element, this lightning arrester generally is installed on the large electric appliances equipment of ground static state, as power station, electric substation, generator etc., install in the incompatible electric locomotive in high-speed cruising, its major defect: (1) Heavy Weight, vibration in the incompatibility locomotive operation, environment under the dynamic conditions such as high speed and acceleration, in the restriction speed of service 120km/h, can not satisfy the requirement of quasi high-speed (180km/h) operation; (2) the external insulation withstand voltage test is limited in the following area of height above sea level 2000m, can not be suitable for mountain area or highlands; (3) this lightning arrester internal cavities adopts gas-insulated (sulphur hexafluoride or nitrogen), because electric locomotive vibration in service is big, ambient temperature, humidity, the air pressure change scope is big, causes the respiration of gas, make airborne moisture invade lightning arrester inside, have a strong impact on the life-span of zinc oxide resistance sheet, also can cause the side of valve block to dodge, even explosion takes place; (4) the porcelain overcoat is fragile in not only transporting and installing, and under the overvoltage effect, pressure discharges and causes comminuted blast easily, causes the broken fault of top electricity and machine, has a strong impact on the person and traffic safety.
The purpose of this utility model is to overcome deficiency and the problem that above-mentioned prior art exists, design a kind of novel electric power locomotive lightning arrester, reach in light weight, good insulation preformance, the dirty property of resistant excellence, the mechanical strength height, hermetically sealed, safety anti-explosives etc. can adapt to the lightning arrester of distinguishing quasi high-speed electric locomotive service conditions in all parts of the country.
The purpose of this utility model can realize in the following manner.
Keep the basic structure that former zinc oxide arrester is made up of insulating coating, chip and upper lower burrs seat three parts, insulating coating is designed to by insulating material outer cover 1 and liner support tube 2 the two affixed whole organic composite sheath that constitute, between organic composite sheath of this integral body and core body 4, there is not the gap, be all-sealed solid insulation thermal conductive material layer 3 fully, upper and lower dish seat the 5, the 6th, the dynamic seal (packing) fastening structure, the outer top of lightning arrester is connected bottom ground connection with high-pressure side.
The utility model is compared with existing lightning arrester and had tangible excellent specific property: 1. volume is little, and is in light weight, is difficult for fragmentation, total weight 14.kg, and full-height 550mm is convenient to the locomotive top and is installed, and helps drawing high speed; 2. good insulation preformance, overcoat creepage distance are fit in the height above sea level 3500m china railway each department environmental condition greater than 1000mm; 3. mechanical strength intensity height, resistance to shock is good, satisfies maximum wind velocity, the synthetic specified bending resistance load of horizontal pull and locomotive running speed 200km/h; 4. fully closed solid insulation system, inner no cavity has been eliminated the hidden danger of invading because of gas respiration moisture basically, raising lightning arrester electric performance stablity and useful life; 5. organic composite sheath safety anti-explosive is fundamentally eliminated the danger of blast, guarantees the person and device security; 6. silicon rubber umbrella cover surface has hydrophobicity, therefore improves the dirty performance of its resistant greatly.
The utility model is described in further detail below in conjunction with drawings and Examples:
Fig. 1 is the utility model front view
Fig. 2 is the structure cutaway view of this lightning arrester
In Fig. 2,1 is silicon rubber full skirt shape insulating material outer cover, and 2 is the liner support tube, and 3 is fully closed solid insulating heat-conduction material layer, and 4 is the zinc oxide resistance sheet core body, and 5,6 is upper and lower dish seat, and 7,8 is metal gasket, and 9 is antirattle spring, and 10 is the endless metal pad.In the present embodiment, insulating material outer cover 1 adopts silicon rubber full skirt shape single piece, liner support tube 2 is an epoxy fibreglass cloth core structure, bonding being integral of inwall of its outer wall and silicon rubber full skirt shape insulating material outer cover 1, constitute organic composite sheath thus, it has in light weight, good insulation preformance, mechanical strength is high by force, the dirty property of resistant excellence, features such as safety anti-explosive, being convenient to the locomotive top installs, be fit to the quasi high-speed electric locomotive 200km/h speed of service, satisfy china railway each department environmental condition, fundamentally eliminate the harm of porcelain overcoat blast, guarantee the person and device security, adopt zinc oxide resistance sheet to be composed in series lightning arrester core body 4, utilize the non-linear voltage-current characteristic of zinc oxide resistance sheet excellence, no afterflow, discharge capacity is big, residual voltage is low, characteristics such as electric performance stablity satisfy insulation coordination, have realized overvoltage protection, lightning arrester inside, break through the technology that traditional lightning arrester fills protective gas, adopt vacuum to pour into insulating heat-conduction material-resin glue, after resin glue fully solidifies, form inwall and this solid insulation thermal conductive material layer 3 complete closely connected no gaps of liner support tube 2, lightning arrester inside becomes the fully closed solid insulation system, and it is in service to have overcome electric locomotive, because the influence that vibration and atmosphere change, cause the respiration of lightning arrester internal gas that moisture is invaded the shortcoming that endangers zinc oxide resistance sheet, the stability and the useful life of having improved the lightning arrester electrical property; Upper lower burrs seat 5, the 6 inner screw threads for fastening that adopt; lower wall seat 6 is established metal gasket 8 with core body 4 bottoms; last dish seat 5 is established metal gasket 7, antirattle spring 9 and endless metal pad 10 with core body 4 tops; constitute the dynamic seal (packing) fastening structure; improve the antivibration ability; the integral body of lightning arrester reaches the version of fully closed solid insulation and dynamic fastening antivibration, has fully guaranteed the overvoltage protection of electric traction and the service conditions of electric locomotive.
