Abstract
The utility model provides a high-tension bushing with a conductive rod and a grounded shield screen. The high-tension bushing comprises the conductive rod, the cylindrical bushing body with an umbrella skirt, the grounded shield screen and an installation flange, which are all poured into a whole through epoxy resin. The conductive rod is combined together with the cylindrical bushing body with the umbrella skirt through the epoxy resin, the grounded shield screen is electrically and mechanically connected with the installation flange, and the two ends of the grounded shield screen are both in a sphere structure, so that the electric field between high and low voltages of a product is uniform, and enough insulation distance is provided.
Description
Technical field
The utility model relates to a kind of bushing, relate in particular to a kind of bushing with conducting rod and earth shield net, being used for rated voltage is high pressure complete set of equipments and the control appliance of 72.5kV, one end passes as partitions such as wall or casings, play conduction, insulation and supporting function, belong to the bushing technical field.
Background technology
Bushing is used for high pressure complete set of equipments and control appliance, and an end of bushing passes partitions such as wall or casing, plays conduction, insulation and supporting function.Existing bushing is the punching structure, only has the earth shield net, but there is no conducting rod, its advantage of the sleeve pipe of this structure is to make simply, be easy to cast, but insulation property is poor, medium is many, volume is large, and when product is done the power frequency withstand voltage test, corona sound is large, the requirement that local discharging level is difficult to be up to state standards.
Summary of the invention
Technical problem to be solved in the utility model is: the problem for prior art exists, a kind of bushing with conducting rod and earth shield net is provided, and to enhance product performance, make its requirement that is up to state standards.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of bushing with conducting rod and earth shield net, comprise conducting rod, be cylindrical band full skirt jacket body, earth shield net and mounting flange, described earth shield net is electrically connected to and mechanical connection with mounting flange, described conducting rod be cylindrical band full skirt jacket body and combine by epoxy resin, making between the high and low pressure of product has enough insulation distances.
Described earth shield net two ends are the spheroidal structure, make the Electric Field Distribution between the high and low pressure of product more even.
The beneficial effects of the utility model are: a kind of bushing with conducting rod and earth shield net of the utility model, can not only effectively improve product dielectric strength, make Electric Field Distribution more even, the operation safety and reliability, the requirements that is up to state standards, and can improve product mechanical strength, reduce product volume, save epoxide resin material, reduce costs, effectively reduce the floor space of product, save the soil.
Description of drawings
Fig. 1 is a kind of bushing structural representation with conducting rod and earth shield net of the utility model.
The 1-conducting rod; 2-is cylindrical band full skirt jacket body; 3-earth shield net; The 4-mounting flange.
Below in conjunction with accompanying drawing, the utility model is described further:
Embodiment
as shown in Figure 1, a kind of bushing with conducting rod and earth shield net, comprise conducting rod 1, be cylindrical band full skirt jacket body 2, earth shield net 3 and mounting flange 4, described earth shield net 3 is electrically connected to and mechanical connection with mounting flange 4, described conducting rod 1 be cylindrical band full skirt jacket body 2 and combine by epoxy resin, described earth shield net 3 two ends are the spheroidal structure, make the height of product, Electric Field Distribution between low pressure is more even, between described conducting rod 1 and earth shield net 3, epoxy resin is arranged, this epoxy resin makes the height of product, enough insulation distances are arranged between low pressure.During use, mounting flange (4) is fixed on mounting panel, and conducting rod (1) reliably is connected with high-pressure side.
Claims (2)
1. bushing with conducting rod and earth shield net, comprise conducting rod, be cylindrical band full skirt jacket body, earth shield net and mounting flange, it is characterized in that: described earth shield net is electrically connected to and mechanical connection with mounting flange, described conducting rod be cylindrical band full skirt jacket body and combine by epoxy resin.
2. a kind of bushing with conducting rod and earth shield net according to claim 1 is characterized in that: described earth shield net two ends are the spheroidal structure.
