Abstract

The utility model relates to an electric insulation equipment for the piping of a transformer, the effect of electric insulation is provided on the junction of the piping of an gas collection circuit and an electricity, that is that the electric insulation equipment is provided on the junction of the pipeline of the connection piping of the gas collection pipeline and the electric terminal box or the shell of the transformer, the high fever of the pipeline of the transformer, which is caused by that the electromagnetism and the current produced by vortex are passed through the piping, is isolated by using an insulating pipe to avoid the overheating of the pipeline and the accessory, thus, the transformer can be safely operated and the service life of the transformer can be ensured.

Description

The electrical insulation device of transformer pipe arrangement

The utility model is the electrical insulation device of and gas collection pipeline pipe arrangement electric about a kind of transformer, and particularly a kind of can being applied on transformer and the external pipe arrangement pipeline in succession of annex thereof makes pipe arrangement obtain good electric insulation effect person.

Generally speaking; the basic role of transformer is a kind of alternating electromagnetism field action and with the electromagnetic machine of electric energy conversion; voltage height based on high-power transformer; electric current is big and for making transformer can fill part its performance of performance and guaranteeing under the condition of safe handling of transformer; generally all set up electric and Machine guarding miscellaneous; therefore must be various electric and Machine guarding with in addition pipe arrangement connection of pipeline; to be communicated with the mutual electric terminal of each protection equipment; in transformer, do not allow gas hold-up improperly therein in addition, so yet must be collected and get rid of with pipeline.

Above-mentioned two kinds join the pipeline that invests on the transformer in addition pipe arrangement be connected to transformer control panel and gas-collection vessel, draw the Surveillance center that receives transformer station again, can guarantee so just that transformer is normal to use and safe handling; But, when pipeline connects into a loop, because transformer is in the running use, each circuit and the equipment electric current that all circulating, and during the pipe arrangement pipeline of electric current by generally making by the high resistance iron material, then electric current will form the circulation of continuous circulation at this high-resistance closing pipe line, cause must producing when electric current is flowed through pipeline high heat, and then influence the transformer normal operation and reduce its useful life.

Main purpose of the present utility model promptly is to provide a kind of and avoids pipe arrangement to flow through because of electric current producing the circulation phenomenon, makes the transformer running normal, and keeps the due useful life of protecting transformer.

In order to achieve the above object, the utility model mainly is to join on the pipe arrangement with a seal, allow pipe arrangement can obtain good electric insulation effect by the protection of seal, be mainly that when implementing joint electric and gas collection pipeline is provided with an electrical insulation device, outwards transmit in order to block the high heat that pipeline internal cause electric current loop miscarriage gives birth to, avoid pipeline and relevant annex to take place overheated and influence the situation of transformer normal operation.The ora terminalis coupling that mainly is to be connected to the electric pipe arrangement junction of transformer is provided with the joint that can axially join each other, this each end connector is to be formed by door, pressing plate, compound the splicing of moist-proof board, and joint each other join more be folded with a flange, this joint and flange are arranged with a plurality of screw holes in the end face correspondence position is first-class, and be arranged in screw hole by bolt, make two joints be bonded with each other, this bolt more is arranged with outward and can completely cuts off electromagnetism that transformer circuit produces and the electric current electric insulation pipe by the high heat that pipe arrangement produced.

Wherein this insulated tube is to be a weather-proof fiberglass pipe.

Relevant detailed description of the present utility model and technology contents cooperate graphic being described as follows, wherein:

Fig. 1 is outward appearance decomposing schematic representation of the present utility model;

Fig. 2 is body picture group of the present utility model; And

Fig. 3 is the generalized section of Fig. 2 along the A-A direction.

Please consult Fig. 1, shown in Figure 2 simultaneously, show the preferred embodiment of the electrical insulation device of the utility model transformer pipe arrangement among the figure; The utility model is mainly used on pipe arrangement 10 bonding stations that transformer sets up, as shown in the figure, joint ora terminalis in two sections pipe arrangements 10 is provided with the door 11 that can axially join each other, and on door 11 end face position of halving, be provided with a plurality of screw holes 12, make two pipe arrangements 10 can by bolt 20 via screw hole 12 with two sections pipe arrangements 10 each other screw lock join; Reach effect moistureproof even reduction beak sound in order to allow joint closely link, on the implementation, pipe arrangement 10 more is folded with the material that pressing plate 13, moist-proof board 14, flange 15 etc. are provided with screw hole 12 equally with door 11 and can run through interlocking via bolt 20 in joint.

In addition, be equipped with electrical wire in the pipe arrangement 10,, therefore can producing heat by the road the time when electric current or magnetic flux flow because pipe arrangement 10 is normally made by metal materials such as iron, for fear of pipe arrangement 10 because of the high resistance of iron produces high heat, destroy insulation and influence the transformer normal operation; The base this, the utility model more is arranged with electric insulation pipe 16 outside bolt 20, this electric insulation pipe 16 is to be a weather-proof fiberglass pipe, it has excellent electrical insulative property, the high heat that effectively anti-system pipe arrangement 10 internal cause current flowing produce is direct or indirect is passed to transformer, guarantees that transformer normally uses.

The above person is preferred embodiment of the present utility model only, is not to be used for limiting the scope that the utility model is implemented.Be that all equalizations of being done according to the utility model claim change and modification, be all the utility model claim and contain.

Claims (2)

1. the electrical insulation device of a transformer pipe arrangement, the ora terminalis coupling that mainly is to be connected to the electric pipe arrangement junction of transformer is provided with the joint that can axially join each other, this each end connector is by door, pressing plate, compound the splicing of moist-proof board forms, and joint each other join more be folded with a flange, this joint and flange are arranged with a plurality of screw holes in the end face correspondence position is first-class, and be arranged in screw hole by bolt, make two joints be bonded with each other, it is characterized in that: this bolt more is arranged with outward and can completely cuts off electromagnetism that transformer circuit produces and the electric current electric insulation pipe by the high heat that pipe arrangement produced.

2. the electrical insulation device of transformer pipe arrangement according to claim 1 is characterized in that, wherein this insulated tube is to be a weather-proof fiberglass pipe.
