Abstract
The utility model discloses a transformer insulating sheath, and relates to the technical field of transformer accessory. The transformer insulating sheath comprises an upper sheath cover and a lower sheath cover. The transformer insulating sheath is characterized in that one side of the upper sheath cover is in flexible connection with one side of the lower sheath cover through a connecting piece, the upper sheath cover is capable of rotating along the connecting piece, the upper sheath cover is fastened with the lower sheath cover to form the sheath with a cavity, the formed sheath is in an oblong structure, half-round gaps are arranged on both lateral sides of the upper sheath cover and the lower sheath cover, incoming and outgoing line holes are formed between combination of the gaps and the sheath cavity, and the incoming and outgoing line holes are communicated with the sheath cavity after the fastening between the upper sheath cover and the lower sheath cover to form the sheath. The transformer insulating sheath is formed by high temperature vulcanization of silastic elastomer, is non-deformational forever, has high flexibility, has service life of 50 years, has good insulation performance, is reasonable in design and convenient to install, and has fastening structure which is convenient for dismounting to reuse in examination and repair.
Description
Technical field
The utility model relates to the transformer accessory technical field, is specifically related to a kind of transformer insulated sheath.
Background technology
Power transmission and transforming equipment, comprising that transformer has much is arranged on open-air lower operation, in the travel fatigue rain and dew, the connector lug position of its wiring insulated terminal is because of the easier generation temperature rise of contact resistance reason, or materials variances has potential difference so the ionization corrosion occurs easily in liquid medium.Again because the setting height(from bottom) of some transformers is not enough to reach safe isolation effect.China Patent No. is 96230958.3 to have proposed insulating shield a kind of taper, that communicate up and down, because identical purpose, but its structure is single, and application surface is narrow, and installation process has inconvenience more.
The utility model content
It is a kind of simple in structure that technical problem to be solved in the utility model is to provide, transformer insulated sheath reasonable in design.
Technical problem to be solved in the utility model realizes by the following technical solutions:
A kind of transformer insulated sheath, comprise upper sleeve cover and lower sleeve cover, it is characterized in that: described upper sleeve cover one side and lower sleeve cover one side are flexibly connected by connector, described upper sleeve cover can rotate with the lower sleeve cover snapping and forms a sheath with inner chamber along connector, the whole rectangular structure of the sheath that forms, be equipped with semicircle breach at upper sleeve cover and lower sleeve cover both sides, behind upper sleeve cover and lower sleeve cover snapping formation sheath, breach is combined and is consisted of the wire inlet/outlet hole identical with sheath lumen.
Described upper sleeve cover and lower sleeve cover are made by silastic material.
Described connector is made by silastic material.
The beneficial effects of the utility model are: the utility model adopts that silastic elastomer is high temperature vulcanized to be formed, with indeformable, and high-flexibility, life-span can reach 50 years, has good insulation property, and is reasonable in design, easy for installation, dismounting is reused during the fastening structure easy access.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
As shown in Figure 1, a kind of transformer insulated sheath, comprise upper sleeve cover 11 and lower sleeve cover 12, upper sleeve cover 11 1 sides and lower sleeve cover 12 1 sides are flexibly connected by connector, upper sleeve cover 11 can rotate with lower sleeve cover 12 snappings and forms a sheath 1 with inner chamber along connector, the sheath 1 whole rectangular structure that forms, be equipped with semicircle breach at upper sleeve cover 11 and lower sleeve cover 12 both sides, after upper sleeve cover 11 and lower sleeve cover 12 snappings formed sheath 1, breach was combined and is consisted of the wire inlet/outlet hole 13 identical with sheath lumen.Upper sleeve cover 11 and lower sleeve cover 12 are made by silastic material, and connector is made by silastic material.The utility model can use in-60 ℃ of-380 ℃ of scopes, has UV resistant, ageing-resistant, and excellent hydrophobicity can satisfy outdoor long-time running.The 2#, the 3# parallel groove clamp that are used for transformer prevent because of the exposed human electric shock who causes of electrical contact point, prevent from the foreign matters such as branch overlap joint or toy creeped causing phase fault, and elimination acid rain is to the corrosion of transformer node, the operation troubles of stopping to cause thus.
More than show and described basic principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
Claims (3)
