Abstract
The utility model discloses a busbar bushing used for a switch cabinet. The busbar bushing used for the switch cabinet comprises a bushing body and a busbar supporting plate. Grading rings are embedded in the bushing body, and the inner walls of bushing body are equipped with lugs; the busbar supporting plate is equipped with a busbar hole used for installing a busbar, and the busbar supporting plate is fixed on the lugs via screws; the busbar supporting plate is equipped with screw holes through which screws penetrate, and the screw holes are circular arc-shaped. The busbar bushing used for the switch cabinet of the utility model is convenient to install the busbar in the bushing, and enables the safety to be improved simultaneously.
Description
Technical field
The utility model relates to a kind of switch cubicle bus-bar casing tube, particularly a kind of 40.5kV bus-bar casing tube for high-voltage switch cabinet.
Background technology
Bus-bar casing tube is the seal of protection busbar between high-voltage switch gear complete set of equipments cabinet and cabinet.Along with the development of high pressure complete set of equipments, the client improves constantly the requirement of bus-bar casing tube.Bus-bar casing tube is arranged on cabinet, busbar need pass bus-bar casing tube, in prior art busbar when mounted, install the position in the busbar hole that can only offer according to bus-bar casing tube, and can't the angle of regulating busbar be installed, can't tackle randomness and the flexibility of on-the-spot transformation.
on the other hand, bus-bar casing tube is arranged on cabinet, busbar need pass bus-bar casing tube, be provided with grading ring inside the inwall of bus-bar casing tube, busbar must be connected with grading ring by high-voltage connection, to obtain uniform electric field preferably, often by one section lead-in wire, busbar is connected with grading ring in prior art, install cumbersome, and must do lead-in wire longer when installing, because the long lead-in wire that makes of lead-in wire contacts with internal surface of sleeve pipe always, like this when long-time running, easy aging breakage is even broken lead-in wire, cause partial discharge, there is insulation hidden danger, security performance is also poor.
The utility model content
For addressing the above problem, the utility model provides a kind of switch cubicle bus-bar casing tube, facilitates busbar to install.
For achieving the above object, switch cubicle bus-bar casing tube of the present utility model comprises sleeve body and busbar supporting bracket, and in described sleeve body, landfill has grading ring, and the inwall of described sleeve body is provided with lug; Described busbar supporting bracket is provided with for the busbar hole that busbar is installed, and described busbar supporting bracket is fixed by screws on described lug, offers screw hole on described busbar supporting bracket, and described screw passes described screw hole, and described screw hole is circular arc.
Busbar goes between by spirality and is connected with described screw, and described screw is connected with described grading ring by wire.
Be provided with a circle conduction transition zone in described busbar hole, described conduction transition zone is connected with described screw by wire, and described screw is connected with described grading ring by wire.
Switch cubicle bus-bar casing tube of the present utility model can adapt to randomness and the flexibility of on-the-spot transformation, has facilitated the installation of busbar in sleeve pipe, has improved simultaneously fail safe.

Embodiment
Referring to Fig. 1 ~ Fig. 4, switch cubicle of the present utility model comprises sleeve body 10 and busbar supporting bracket 20 with bus-bar casing tube, and the interior landfill of described sleeve body 10 has grading ring 12, and the inwall of described sleeve body 10 is provided with lug 11; Described busbar supporting bracket 20 is provided with for the busbar hole 21 that busbar 100 is installed, described busbar supporting bracket 20 is fixed on described lug 11 by screw 13, offer screw hole 22 on described busbar supporting bracket 20, described screw 13 passes described screw hole 22, and described screw hole 22 is circular arc.When mounted, busbar 100 passes the busbar hole 21 on described busbar supporting bracket 20, the shape in busbar hole 21 and busbar 100 couplings, screw 13 is being locked before on lug 11, can first rotate busbar supporting bracket 20, screw 13 relatively moves in the screw hole 22 of circular arc, regulates the setting angle of busbar 100, lock-screw 13 again after regulating, busbar supporting bracket 20 is fixing.
Referring to Fig. 2, busbar 100 goes between by spirality and 14 is connected with described screw 13, and described screw 13 is connected with described grading ring 12 by wire.Described busbar 100 adopts spirality lead-in wire 14 to be connected with described screw 13, spirality lead-in wire 14 can elongate a segment distance when mounted, make busbar 100 and the tie point of lead-in wire 14 to install in the outside of sleeve body 10, install rear mobile busbar 100, make tie point move to sleeve body 10 inside.
With the another kind of execution mode of bus-bar casing tube, only set forth the place different from the execution mode shown in Fig. 1 ~ Fig. 4 referring to Fig. 5 and switch cubicle of the present utility model shown in Figure 6 here.Be provided with a circle conduction transition zone 15 in described busbar hole 21, described conduction transition zone 15 is connected with described screw 13 by wire, and described screw 13 is connected with described grading ring 12 by wire.By conduction transition zone 15, can guarantee to have reliable the contact with busbar 100.Described conduction transition zone 15 can adopt the soft materials such as conductive rubber, conduction cardboard, capillary copper brush, and certainly, this conduction transition zone 15 also can adopt soft semiconductive material.
