Abstract
The invention relates to an insulator for gas insulation switchgear. The insulator for the gas insulation switch gear comprises an insulator body, wherein mounting holes are evenly distributed in the upper end of the insulator body. The insulator for the gas insulation switchgear further comprises a pouring gate, wherein the pouring gate is formed in the middle of the upper end face of the insulator body, and the diameter of the pouring gate is 40-60mm. Due to the fact that the pouring gate of the insulator for the gas insulation switchgear is formed in the middle of the insulator, the diameter of the pouring gate can be enlarged, air can be directly discharged from the pouring gate in the downward moving process of materials when the materials are poured, bubbles are effectively prevented from being generated in the insulator, and the quality of the insulator is improved greatly.
Description
Technical field
The present invention relates to a kind of insulator, a kind of gas-insulated switchgear insulator of specific design.
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.
Summary of the invention:
In sum, for overcoming defect and the deficiency existing in prior art, the invention provides a kind of gas-insulated switchgear insulator.The technical scheme that the present invention takes is:
A 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 invention has the beneficial effects as follows: the present invention 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, when material is poured into a mould, at material, move downward in process, air can directly be discharged from cast gate, effectively avoid the generation of bubble in insulator, greatly improved the quality of insulator.
Accompanying drawing explanation
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 invention;
Fig. 4 is vertical view of the present invention.
In figure: 1, insulator body; 2, cast gate; 3, cap mouth; 4, installing hole.
Embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing, embodiment of the present invention 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, when material is poured into a mould, at material, move downward in process, 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 to the explanation of technical solution of the present invention and unrestricted, other modification that is equal to replacement or makes according to prior art of person of an ordinary skill in the technical field is as long as no the thinking and the scope that exceed technical solution of the present invention, within all should being included in right of the presently claimed invention and scope.
