Abstract
The utility model relates to an insulator for gas insulated switchgear. The insulator comprises an insulator body. Mounting holes are uniformly distributed on the upper end of the insulator body. The insulator further comprises a pouring gate which is arranged in the center position of the upper end face of the insulator. The diameter of the pouring gate is 40 to 60 mm. As the pouring gate of the insulator of the utility model is arranged in the center of the insulator, the diameter of the pouring gate can be enlarged so that when a material is poured, air can be discharged directly from the pouring gate during the process that the material moves downwards. Therefore, the generation of air bubbles in the insulator is prevented and the quality of the insulator is improved substantially.
Description
Technical field
The utility model relates to a kind of insulator, is specifically related to a kind of gas-insulated switchgear insulator.
Background technology
Existing gas-insulated switchgear insulator is hollow structure, wall ratio is thinner, in manufacture process, cast gate is arranged between two installing holes on top of insulator, because wall ratio is thinner, the diameter at sprue gate is smaller, in the process of cast, find, because wall ratio is thinner, the reason that the diameter at sprue gate is smaller, there is Bubble formation on the top of insulator, can affect the quality of insulator.
Utility model content:
In sum, for overcoming the defect and the deficiency that exist in prior art, the utility model provides a kind of gas-insulated switchgear insulator.The technical scheme that the utility model is taked is:
A kind of gas-insulated switchgear insulator, comprises that insulator body, insulator body upper end are evenly distributed with installing hole, also comprises cast gate, and described cast gate is arranged on centre position, insulator upper surface, and described gate diameter is 40-60mm.
Further: described gate diameter is 50mm.
The beneficial effects of the utility model are: the utility model is because gas-insulated switchgear is arranged on the centre of insulator with the cast gate of insulator, can increase the diameter of cast gate, in the time that material is poured into a mould, move downward in process at material, air can directly be discharged from cast gate, effectively avoid the generation of bubble in insulator, greatly improved the quality of insulator.
Brief description of the drawings
Fig. 1 is the structural representation of prior art;
Fig. 2 is the vertical view of prior art;
Fig. 3 is structural representation of the present utility model;
Fig. 4 is vertical view of the present utility model.
In figure: 1, insulator body; 2, cast gate; 3, cap mouth; 4, installing hole.
Embodiment
For making the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing, the utility model execution mode is described in further detail.
As shown in Figure 3, Figure 4, the present embodiment provides a kind of gas-insulated switchgear insulator, comprise that insulator body 1, insulator body 1 upper end are evenly distributed with installing hole 4, also comprise cast gate 2, described cast gate 2 is arranged on centre position, insulator upper surface, and described cast gate 2 diameters are 40-60mm.
Further, described cast gate 2 diameters are 50mm.
In use, owing to gas-insulated switchgear is arranged on to the centre of insulator with the cast gate of insulator, increase the diameter of cast gate, in the time that material is poured into a mould, move downward in process at material, air can directly be discharged from cast gate, has effectively avoided the generation of bubble in insulator, has greatly improved the quality of insulator.
It should be noted that, above-described execution mode is explanation to technical solutions of the utility model and unrestricted, person of an ordinary skill in the technical field be equal to replace or make according to prior art other revise as long as no the thinking and the scope that exceed technical solutions of the utility model, within all should being included in the desired right of the utility model and scope.
Claims (2)
