Abstract
The utility model relates to a disk insulator, belonging to the technical field of electrical equipment. The product comprises a disk insulating main body made of non-metal material. The improvement is that the outer edge of the insulating main body is fixedly connected with a metal outer ring, and the metal outer ring is provided with a penetrable hole matched with a flange. Therefore, by virtue of the good mechanical property of the metal outer ring, an insulating salver can effectively balance the stress applied on the salver by the flange, and the damage probably caused by the fracture of the salver due to internal fault can be obviously reduced.
Description
Technical field
The utility model relates to the insulator on a kind of combined electrical apparatus, and especially a kind of disc insulator belongs to technical field of electric appliances.
Background technology
At present, the insulating basin 1 on the high-voltage closed combined electrical apparatus (GIS) is formed by the epoxy resin integral vacuum pouring as shown in Figure 1, plays supportive conductors and insulation in product.General fixed form is to be clipped between two flanges 2, is fixed together with the latter with bolt 5.3 is seals among Fig. 1.Facts have proved that there are the following problems for such structure: the one, be in operation, the product temperature influence can make the very big external stress of generation on the insulating basin, and the result causes it destroyed easily, leads to a disaster; The 2nd, when serious arc fault appearred in enclosure interior, insulating basin can cracked hurting sb.'s feelings.Though many manufacturing firms all once made great efforts head it off, effect is barely satisfactory.
The utility model content
The purpose of this utility model is: at the shortcoming that above-mentioned prior art exists, a kind of disc insulator of damaging can effectively avoided is proposed, thus the reduction accident risk.
In order to reach above purpose, disc insulator of the present utility model contains the peviform insulating body that nonmetallic materials are made, and its improvements are: the outer rim of described insulating body is fixedlyed connected with the metal outer ring, and described metal outer ring is shaped on the perforation that matches with flange.
The purpose of this utility model is further realized by following technical scheme: described insulating body is made by epoxy resin, and described metal outer ring is the aluminium outer ring.
Like this, during installation, the metal outer ring is clipped between two flanges, with bolt that it is fixed with each other again.By metal outer ring favorable mechanical performance, can make insulating basin active balance flange to its stress that applies, and significantly lower the harm that internal fault makes basin break and may cause.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
The mounting structure partial schematic diagram of the existing disc insulator of Fig. 1.
Fig. 2 is the partial structurtes schematic diagram of an embodiment of the utility model.
Embodiment
Embodiment one
The disc insulator of present embodiment as shown in Figure 2, the peviform insulating body 4 and the aluminium outer ring 1 of being made by epoxy resin constitute.The outer rim middle part of insulating body forms flange, and the corresponding internal circular surfaces of aluminium outer ring 4 forms the groove that matches with flange, and insulating body 4 is fixed together with chimeric the fitting tightly of aluminium outer ring 1 by described flange and groove.Aluminium outer ring 1 is shaped on the perforation that installs bolt 5 that matches with flange 2.Insulating body 4 is embedded with seal 3 with the flange bonding surfaces.
Original integral type disc insulator is when bearing the electric arc heat of internal fault, and epoxy resin is hit easily and produces fragment, and the aluminium outer ring structure of present embodiment then can effectively prevent the generation of this type of situation.Simultaneously, when causing when the electric current variation in the electrical equipment or variations in temperature that shell is flexible and causing flange 2 to produce the compression stress power, can not act directly on the body of epoxy resin, but act on the metalwork, thereby avoid the stress damage of insulating body.
Facts have proved that after the structure of employing present embodiment, insulating basin can break to personnel's injury basin to its stress that applies and the obvious internal fault that lowers by the active balance flange.
In addition to the implementation, the utility model can also have other execution modes.All employings are equal to the technical scheme of replacement or equivalent transformation formation, all drop on the protection range of the utility model requirement.
Claims (4)
