Abstract

The utility model discloses a connecting conductor with an adjustable angle, which consists of two shielded conductors matched and fixedly connected. Each shielded conductor in a beveled hemisphere form comprises a bottom face, a spherical face and a beveled face, the beveled face is a joint face of the two conductors, a boss is peripherally arranged on the beveled face of one of the shield conductors, a connection through hole for a bolt to penetrate through is arranged on a central axis of one of the shielded conductor, a groove matched with the boss is arranged on the beveled face of the other one of the shielded conductors, while a threaded hole matched with the bolt is arranged on the central axis, the beveled faces of the two shielded conductors are combined and tightly connected through the bolt, and a fixed conductor is fixedly connected with the shielded conductors through the bottom face. The connecting conductor has the advantages that less conductors can conveniently realize multi-angle internal conduction, angle matching of the upper shielding and the lower shielding falls in one to one correspondence with guarantee by special tooling, connection of the two conductors is more reliable, can bear larger torque force and bending force, and the connecting conductor has less part types, is low in manufacturing cost and convenient in detachment.

Description

A kind of bonding conductor of adjustable angle

Technical field: the utility model relates to the power switchgear field, particularly a kind of bonding conductor that is used for Cubicle Gas-Insulated Switchgear (GIS) adjustable angle of 252kV and above electric pressure thereof.

Background technology: at present, in the layout of the Cubicle Gas-Insulated Switchgear (GIS) of 252kV and above electric pressure thereof, the connection form through different angles appear in regular meeting realizes with regard to the conductor that needs equal angular in inside.But angle may be all different when arranging for each equipment, this just needs the inner conductor that different angles are set to come corresponding, that is to say the identical but angle difference of conductor function, realize the angle of different angles, guarantee with regard to the frock that needs different angles, the frock kind is many, makes that the conductor part kind is many, versatility is not high.The center is carried out the fastening hidden danger that exists by a screw rod to two junction, makes conductor occur rotating relative to central axis when being subjected to bigger radial load, influences equipment safety operation.

The utility model content: for solve multi-angle in the prior art, multiple class conductor connect loaded down with trivial details, the part kind is many, the problem of versatility difference, the purpose of this utility model is to provide a kind of bonding conductor of adjustable angle, the multi-angle conductor is fused on two or a few parts, simultaneously simple installation and firm.

For reaching above purpose, the utility model takes following technical scheme to be achieved: a kind of bonding conductor of adjustable angle, cooperate and be formed by fixedly connecting by two shield type conductors, it is characterized in that: described shield type conductor is the dome-type of cutting sth. askew, comprise the bottom surface, sphere and scarf, scarf is the faying face of two conductors, the scarf of one of them shield type conductor is along being circumferentially with boss, the axis is provided with the connecting through hole that passes for bolt, the scarf of another shield type conductor is along being circumferentially with the groove that cooperates with boss, the axis is provided with the screwed hole that cooperates with bolt, the scarf of two shield type conductors in conjunction with and connect by bolted, fixed conductor is fixedlyed connected with the shield type conductor by scarf.

Preferably, described boss, groove are circumferentially evenly arranged along shield type conductor scarf.

Advantage of the present utility model is to lead in the multi-angle available a small amount of conductor and realizes easily, it is one to one that the angle of upper and lower shield type conductor cooperates, do not need special tooling to guarantee, both connections are more reliable simultaneously, can carry bigger torsional forces and bending moment force, the part kind is few, low cost of manufacture, conductor easy accessibility.

Description of drawings: Fig. 1 is the maximum angle combining structure schematic diagram of the utility model embodiment; Fig. 2 is the α combination of angles structural representation of the utility model embodiment; Fig. 3 is the minimum angles combining structure schematic diagram of the utility model embodiment; Fig. 4 is the structural representation of last shield type conductor; Fig. 5 is the A-A cut-away view of Fig. 4; Fig. 6 is the structural representation of following shield type conductor; Fig. 7 is among the B-B cut-away view figure of Fig. 6: 1, go up the shield type conductor; 2, connecting bolt; 3, following shield type conductor; 4, fixed conductor; 5, disc insulator;

Embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and instantiation.

As shown in Figure 1, the utility model comprises, following two dome-type shield type conductors 1 of cutting sth. askew, 3,

shield type conductor

1,3 comprise bottom surface 1a and 3a respectively,

sphere

1b and 3b,

scarf

1c and 3c, the angle of bottom surface and scarf is between 15 °～45 °, in conjunction with Fig. 4, shown in Figure 5, the bottom surface 1a of one of them shield type conductor 1 is along circumferentially evenly being provided with some boss 6, be provided with the connecting through hole 7 that passes for bolt along the hemisphere axis, in conjunction with Fig. 6, shown in Figure 7, the bottom surface 3a of another shield type conductor 3 is provided with the groove 8 that cooperates with boss 6, be provided with the screwed hole 9 that cooperates with bolt along the hemisphere axis, on, the bottom surface of following shield type conductor in conjunction with and be fastenedly connected by bolt 2, fixed conductor 4 is by scarf 3c and

shield type conductor

1 and 3 firm connections.The size of the radius of sphericity of upper and lower shield type conductor and the external diameter of fixed conductor and the electric pressure height and the size of current of being carried are relevant.

During installation, earlier the center conductor with fixed conductor 4 one ends and disc insulator 5 is fastenedly connected, and the other end is fastenedly connected with following shield type conductor 3, and during shield type conductor 1, elder generation is with connecting bolt 2 on screwed hole on connecting, but the not serious bolt 2 that is solidly connected.The center line of above subsequently shield type conductor 1 is an axle, and arbitrarily the shield type conductor is gone up in rotation, is fastenedly connected bolt 2 after making the angle on two sides reach the angle that needs.

The along the circumferential direction equally distributed quantity n of groove or boss and need the number of angles N of conversion that relation is arranged, n=2N under one situation.In rotation during shield type conductor 1, quantity n according to groove or boss, can both realize 0? (the x2 of 2 α/n), (the x4 of 2 α/n), (2 α/n) xn amounts to the combination of n/2 kind angle, during design for easy for installation and be difficult for makeing mistakes, in shielding 3 least significant end groove down, make " * " mark according to the marker method of Fig. 6, marker method according to Fig. 4 is made " 1; 2; 3 ... " mark on the boss of last shielding 1, when needs are realized the α angle, the boss that only needs to go up sequence number n/2 in the shielding 1 combines with " * " groove of shielding 3 down, can realize the combination of α angle behind the fastening bolt 2.As Fig. 2, shown in Figure 3, the realization of all the other angles and the like.

Above content is the detailed description of the utility model being done in conjunction with concrete optimal way; can not assert that execution mode of the present utility model only limits to this; for the utility model person of an ordinary skill in the technical field; all any simple modification and equivalent structure transformation or modifications of being done according to the utility model spirit all belong to the definite scope of patent protection of claims that the utility model is submitted to.
