Abstract
The utility model provides an insulation clamping protective device for a lead bracket of a high voltage transformer, which comprises a lead fixed on the bracket, a corrugated board wound and covered on the periphery of the lead, a supplementary insulation wound and covered on the periphery of the corrugated board and a fixing device for fixing the lead, the corrugated board and the supplementary insulation onto the bracket. According to the insulation clamping protective device for the lead bracket of the high voltage transformer, the creepage distance between the lead and the clamping bracket is effectively shortened, and electric safety distance of the lead and effective irradiation are guaranteed.
Description
Technical field
The utility model belongs to high-tension transformer and makes field, particularly a kind of high-tension transformer down-lead bracket clamping part insulation protection device.
Background technology
Lead-in wire in the electric power oil-immersed type transformer, is provided with support lead-in wire is carried out effective clamping in the lead-in wire spill process through the stent support arranged, and needing considers to go between passes through the field intensity of part, to guarantee lead-in wire electrical safety distance on every side.Along with the rising of electric pressure, lead-in wire and the also increasing thereupon of electrical safety spacing of each parts on every side receive the restriction of spatial placement, and consider that from the economy equal angles transformer can not amplify simply.Thereby need and a kind ofly can reliably guarantee the needed electrical safety spacing of high voltage lead and necessary creepage distance, the lead wire insulation device that the transformer body is reduced as far as possible.
The utility model content
The utility model provides a kind of high-tension transformer down-lead bracket clamping insulation protection device, when the improvement lead-in wire is through the part electric field, reduces and the electric creepage distance that passes through support.
The utility model adopts following technical scheme:
A kind of high-tension transformer down-lead bracket clamping insulation protection device; Comprise the lead-in wire that is fixed on the support; The wrapped corrugated board that is divided into a circle small oil gap at the go between periphery and the outer surface that will go between; The wrapped insulation that attaches in the corrugated board periphery, and with lead-in wire, corrugated board with attach insulation and be fixed on the fixture on the support.
Said fixture is a heat-shrink tube; Said corrugated board is fixed on the lead-in wire periphery through cotton cord.
Compared with prior art; The utility model insulation protection device has following beneficial effect at least: the utility model down-lead bracket clamping insulation protection device; The corrugated board that adopts is smooth the leading to of oil of effective assurance lead-in wire outer surface; The outer surface that will go between is divided into a circle small oil gap structure, has improved the electric tolerance intensity of protection part; Corrugated board adds bag and attaches insulation, has increased the creepage distance of lead-in wire and support; Thereby under the situation that the lead-in wire of high voltage, high field intensity passes through equally; The utility model insulation protection device creepage distance with clamping wood part that can reduce greatly to go between; Improve the field intensity of lead-in wire through part; Improve electrical strength and security reliability, and it is compacter reliable that whole lead-in wire is arranged, thereby reduce the volume of whole transformer.
Description of drawings
Fig. 1 is the structural representation of the utility model device.
Fig. 2 is the side sectional view of the utility model device.
Embodiment
Below in conjunction with accompanying drawing the utility model device is done and to be further described:
The utility model high-tension transformer down-lead bracket clamping insulation protection device comprises: be fixed on the lead-in wire 6 on the support 1; Wrapped corrugated board 5 in lead-in wire 6 peripheries; Wrapped corrugated board 5 peripheries and near support 1 colligation fixed position attach insulation 4, and will go between 6, corrugated board 5, attach the cotton cord 3 that insulation 4 is fixed on the heat-shrink tube 2 on the support and corrugated board 5 is fixed on the periphery that goes between.
During installation, at first confirm suitable lead-in wire size and insulation thickness thereof earlier according to electric pressure, the field intensity of pass through lead-in wire; Use this device clamping at support through the position, corrugated board 5 outer surface that will go between is divided into one and encloses small oil gap; With cotton cord 3 corrugated board 5 is fixed on the lead-in wire 6, whole device is fixed on the support 1 with said heat-shrink tube 2.
The utility model can effectively reduce the creepage distance of lead-in wire to support, improves the field intensity of lead-in wire through part, and it is compact reliable that lead-in wire is arranged, thereby reduces the volume of transformer, and cost is lower.
The above is merely a kind of execution mode of the utility model; It or not whole or unique execution mode; The conversion of any equivalence that those of ordinary skills take the utility model technical scheme through reading the utility model specification, the claim that is the utility model contains.
