On the periphery of said connection contact in indoor conductor, outdoor conductor and connection contact at least one and its junction are provided with the groove of the end that is used to contain corresponding link, and said groove is to the inner recess of connection contact.
Said connection contact is provided with the shielding cap of T shape in the insulator position relative with its junction.
Be provided with the groove that is used to contain drain terminal outside the T shape shielding cap on the periphery of said connection contact to the connection contact inner recess in the placement of T shape shielding cap.
The technical scheme of the supporting construction of the center conductor of this ultra high voltage wall bushing is following:
A kind of ultra high voltage wall bushing; Comprise the center conductor that is provided with in body through walls and the body through walls; Said center conductor is broken as indoor conductor and outdoor conductor two parts, and said indoor conductor is crossed the connection contact that is provided with between the two with outdoor conductor dbus and is fixedly connected, and said connection contact is fixed on the inside of cylindrical shell through walls through insulator fixing on its periphery; One end of said insulator is fixed on the periphery of connection contact, and the other end is fixed on the perisporium of body through walls.
On the periphery of said connection contact in indoor conductor, outdoor conductor and connection contact at least one and its junction are provided with the groove of the end that is used to contain corresponding link, and said groove is to the inner recess of connection contact.
Said connection contact is provided with the shielding cap of T shape in the insulator position relative with its junction.
Be provided with the groove that is used to contain drain terminal outside the T shape shielding cap on the periphery of said connection contact to the connection contact inner recess in the placement of T shape shielding cap.
Said insulator is fixed on the perisporium of wall bushing through flange fixing on the perisporium of body through walls, and said flange is fixed on the outer stomidium of the through hole of offering on the body perisporium through walls along last.
Center conductor is divided into indoor conductor and outdoor conductor two parts among the present invention; Indoor conductor and outdoor conductor dbus are crossed the supporting construction that is provided with in the body through walls and are fixed in the body through walls; This supporting construction has the connection contact that indoor conductor and outdoor conductor are fixed together; And connection contact is fixed on the inwall of body through walls through the insulator that is fixedly connected with it; Because the length of center conductor is made up of the length of indoor conductor and outdoor conductor; Just the length of center conductor is made up of two general length or smaller length, thereby has solved the long excessive problem of center conductor amount of deflection that causes of length because of center conductor, and then the problem of having avoided the electric field in the wall bushing to concentrate.Simultaneously, because this wall bushing is simple in structure, insulator, connection contact and flange are common part, so this wall bushing has repacking simply, characteristics cheap for manufacturing cost.
Description of drawings
Fig. 1 is the structural representation of embodiments of the invention.
Embodiment
The embodiment of extra-high voltage direct-current wall bushing of the present invention: as shown in Figure 1; This ultra high voltage wall bushing mainly is made up of with center conductor tubular body 1 through walls; Wherein, Center conductor is broken as indoor conductor 4 and outdoor conductor 3 two parts from the middle part; Indoor conductor 4 is connected through the supporting construction that is provided with in the body 1 through walls with outdoor conductor 3, and supporting construction mainly is made up of connection contact 2 and pillar insulator 5, and wherein connection contact 2 is for being in the connection contact 2 of the hollow ball-shape between indoor conductor 3 and the outdoor conductor 4; There is certain distance between the inwall of connection contact 2 and body through walls 1; Connection contact 2 is fixedly connected through the pillar insulator 5 that is provided with between the two with body 1 through walls, and these insulator 5 one ends are fixedly connected with connection contact 2, and the other end is fixed on flange 6 the inners fixing on body 1 perisporium through walls; Flange 6 is fixed on the outer stomidium of the through hole of offering in position, insulator 5 placement on the body 1 through walls along last; In use, the center conductor that is made up of indoor conductor 3 and outdoor conductor 4 in this wall bushing can effectively be shared the length of center conductor in the prior art to two conductors, thereby the length separately of feasible two conductors that are used to constitute center conductor generally or shorter; And then avoided because the long center conductor amount of deflection that causes of center conductor length is bigger the problem that body 1 internal electric field through walls is concentrated.
Simultaneously; The connection contact 2 of hollow ball-shape is provided with the groove to connection contact 2 inner recess with the junction of insulator 5, indoor conductor 4 and outdoor conductor 3; This groove can contain the termination of insulator 5, indoor conductor 4 and outdoor conductor 3; Thereby make three's end shielded, and then make that near the Electric Field Distribution of connection contact 2 is more even, thereby reduced the adverse effect of connection contact 2 and 5 pairs of sleeve inner Electric Field Distribution through walls of insulator by the perisporium of connection contact.
In addition; Be equiped with T shape shielding cap on the position relative on the connection contact with said junction; Be threaded on this T shape shielding cap bottom cylinder; Can guarantee to be connected more reliably between connection contact and the insulator, connection contact is provided with the arc groove that is used to contain drain terminal outside the T shape shielding cap to the connection contact inner recess in the placement of T shape shielding cap, and near the electric field that this groove and T shape shielding cap upper circular cover can reduce the connection contact is concentrated.
