At present, it is to adopt plain edition disc insulator that domestic relevant High-Voltage Electrical Appliances are manufactured commercial city, the structure of this insulator as shown in Figure 1 and Figure 2, be by three straight center conducting rods 3 are fixed in corresponding mould, the casting gate 9 by mould comes to mould injection ring epoxy resins 2 cooling formings under the condition of vacuum.For guaranteeing the air-tightness of assembling, on epoxy resin 2, be provided with sealed groove 4 and be bolted hole 5 and be assembled together with tank body, when disc insulator assembles with conducting rod, by the retaining thread hole 6 on central conductor leader 3, lock and be connected, and in disc insulator flange 1 outside, nameplate 8 is housed.
In use there is following shortcoming in above-mentioned plain edition disc insulator: 1, because central conductor leader 3 is linear pattern, when running into conducting rod and need to turn, can increase designer's design difficulty, thereby cause the increase of cost of parts; 2, the material of epoxy resin 2 periphery flanges 1 is also epoxy resin, and mechanical strength is low, easily breaks.
summary of the invention
The utility model, for the problems referred to above, provides a kind of disc insulator that turns to, and this turns to disc insulator when conducting rod need to turn, and can reduce the design difficulty of conducting rod, reduces the cost of part.
According to the technical solution of the utility model: a kind of disc insulator that turns to, comprise the epoxy resin of peviform and be arranged in the central conductor leader in described epoxy resin, described central conductor leader comprise connecting plate and be arranged in described connecting plate both sides opposite end, perpendicular to the body of rod of described connecting plate.
On the outer face of the described body of rod, be furnished with screwed hole.
Described central conductor leader has three.
The material of described epoxy resin periphery flange is metal.
On described flange, be furnished with bolt fixing hole.
On the inwall of described flange, be provided with spacing hole.
On the outer wall of described flange, be fixed with nameplate.
On two sides of described epoxy resin, near described flange, be provided with sealed groove.
Technique effect of the present utility model is: the central conductor leader in the utility model is Z-shaped, do not need the conducting rod being connected with it again to turn to, be convenient to conducting rod standardized production in enormous quantities, can reduce the part process-cycle, cost-saving, also easier modular assembly; The metal flange of epoxy resin periphery, can make disc insulator internal electric field be evenly distributed, and more meets design requirement, and metal flange can extend the useful life of disc insulator in addition.
