At present, well-known 10kv Outdoor Trusses For Transformer Substation formula isolating switch is take GW4-10 type switch as main, this equipment install at the beginning of every technical data all in standard, but operation soon, running part, current-carrying part is all easy to go wrong, running part operating physical force strengthens, drive the porcelain vase rotating part corrosion current-carrying part fingertip extension spring of moving contact to lose efficacy, pressure between moving contact and fixed contact reduces, contact resistance increases, cause moving, between fixed contact, generate heat, the serious isolating switch that causes burns, not yet find on the market to solve fingertip extension spring, the corrosions such as contact cause disconnecting link loose contact, heating, even burn problem, and can alleviate a kind of Outdoor Trusses For Transformer Substation formula isolating switch of operating personnel's labour intensity.
Summary of the invention
The purpose of this utility model is to provide a kind of Outdoor Trusses For Transformer Substation formula isolating switch, this isolating switch has advantages of that transmission performance is good and safe and reliable, reduce because of disconnecting link contact wind and weather, the corrosions such as fingertip extension spring and contact cause disconnecting link loose contact, heating, even burn the economic loss of bringing to transformer station.
The utility model is achieved like this, it is made up of framework, support, contact system, insulation system and drive system, it is characterized in that contact system is connected with insulation system to be arranged on support upper end, and support lower end is connecting frame and drive system respectively.
Framework described in the utility model is made up of bearing box and bearing, and bearing seal, in bearing box, and is marked with lubricant in bearing box.
Support described in the utility model, both sides are furnished with closed orbit, seesaw for bearing.
Contact system described in the utility model comprises moving contact and fixed contact, and moving contact, by plum blossom finger contact sheet, has 12, and external application fingertip spring is fixed; Fixed contact is configured to integrated cylindrical.
Insulation system described in the utility model is made up of disjunctor insulator, epoxy resin insulator and outdoor semicircle cartridge type transparent insulation cover.
Drive system described in the utility model is made up of Worm gear mechanism, reducing gear case and hand-rail type operating mechanism.
Effect of the present utility model is: solved because of disconnecting link contact wind and weather, the corrosions such as fingertip extension spring and contact cause disconnecting link loose contact, heating, the problem of burning even, reduce the economic loss that transformer station brings, alleviated operating personnel's labour intensity by worm-drive reducing gear.
