Abstract
The utility model relates to a connecting piece in cable accessories of a high-voltage, ultra high-voltage electrical connection system, in particular to an epoxy seat used for cable accessories. The epoxy seat comprises an epoxy seat body (1), an upper insert (2) and a lower insert (3), wherein the upper insert (2) is arranged on the upper part of the inner side of the epoxy seat body (1); the lower insert (2) is arranged on the lower part of the epoxy seat body (1); the lower insert (3) is inserted inside the epoxy seat body (1) form the lower end of the epoxy seat body (1); the upper insert (2) has a split structure, and comprises an upper insert body (4), an upper link ring (5) and a lower link ring (6); and both the upper insert body (4) and the lower insert (3) are made of a conductive epoxy resin or a conductive rubber conductive polymer material. The utility model has the advantages of simple structure, little possibility of cracking of the epoxy seat, little possibility of occurrence of fault, and long service life. The utility model modifies the traditional technical bias, and solves the technical difficulty which can not be solved in the long term.
Description
Technical field
The utility model relates to the connector in a kind of high pressure, the ultrahigh voltage power connected system, particularly a kind of epoxy seat for cable accessories.
Background technology
At present, in high pressure, ultrahigh voltage power connected system, when the 35KV-500KV cable is connected with Cubicle Gas-Insulated Switchgear or transformer, need be connected with it by cable termination, this cable termination is GIS terminal or transformer terminal, and the crucial connector of terminal is an epoxy seat.At present, the primary structure of epoxy seat (as shown in Figure 1), it comprises epoxy seat body 1, last inserts 2, following inserts 3, last inserts 2 is arranged on the top of the inboard of epoxy seat body 1, following inserts 3 is arranged on the bottom of epoxy seat body 1, following inserts 3 embeds epoxy seat body 1 inside from epoxy seat body 1 lower end, last inserts 2 is the overall structure pattern, and last inserts 2 and following inserts 3 are generally made by metallic conduction materials such as aluminium, aluminium alloy or copper materials.Epoxy seat body 1 material generally is an epoxy resin, has connecting hole 7 on the last inserts 2, is provided with becket 9 in the connecting hole 7, and following inserts 3 is provided with thread bush 8.Present this structural cable annex exists following defective with epoxy seat: the main components that plays the bucking electrode effect in the epoxy seat is a metal insert, promptly go up inserts and following inserts, because the difference of material and the difference of the coefficient of expansion between metal insert and the epoxy seat body, cause epoxy seat internal stress in running to increase, make epoxy seat easy to crack, break down easily during the product operation; While can not well fit owing to metal insert also can air gap occur with the face of epoxy seat body combination because of material is different, thereby influences the service life of product.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of simple in structure, epoxy seat is not easy to crack, be difficult for breaking down after the operation, epoxy seat for cable accessories that service life is long.
Realize that the above-mentioned purpose technical scheme is: a kind of epoxy seat for cable accessories, comprise epoxy seat body, last inserts, following inserts, last inserts is arranged on the top of epoxy seat body inboard, following inserts is arranged on the bottom of epoxy seat body, following inserts embeds the epoxy seat body interior from epoxy seat body lower end, last inserts is the split structural shape, and last inserts comprises inserts body, last connecting ring, following connecting ring, and last inserts body and following inserts are made by conductive epoxy resin or conductive rubber.
Further, described going up on the connecting ring has connecting hole, is provided with becket in the connecting hole, and described inserts down is provided with thread bush.
Further, the described connecting ring of going up is made by aluminium or aluminium alloy or copper material metallic conduction material.
Further, described down connecting ring is made by aluminium or aluminium alloy or copper material metallic conduction material.
After adopting technique scheme, have a lot of benefits: the utility model is simple in structure, epoxy seat is not easy to crack, be difficult for breaking down after the operation, service life is long.It is the structural shape of inserts with the metal that the utility model is changed traditional, changing into last inserts body and following inserts with conductive epoxy resin or conductive rubber is the structural shape of inserts, can play the effect of bucking electrode, epoxy seat internal stress in running is reduced, make epoxy seat not easy to crack like this, make the product security of operation, be difficult for breaking down, reduced the failure rate of product, the fail safe of power cable system is improved greatly; Because the improvement of inserts material is innovated, and it is good that the face that inserts is combined with the epoxy seat body is fitted, improved the service life of product so greatly simultaneously.The utility model changes the overall structure pattern that goes up inserts in the prior art into the split structural shape dexterously, when making last inserts body in the inserts play shielding action and applying effect, also by the connecting hole on the last connecting ring and down connecting ring kept and gone up multinomial functions such as the original connection of inserts, load and sealing in the prior art; Inserts down of the present utility model has kept by connecting hole goes up multinomial functions such as the original connection of inserts, load and sealing in the prior art.The utility model is changed traditional technology prejudice, has solved the long-term indeterminable technical barrier of people with simple structure and design cleverly.
