Abstract
The utility model relates to an insulating sheath which comprises a hood-shaped sheath, a tubular sheath and an annular strengthening rib, wherein the hood-shaped sheath is arranged at the lower partof the tubular sheath, the annular strengthening rib is arranged on the outer side of the tubular sheath, the hood-shaped sheath, the tubular sheath and the annular strengthening rib adopt an integralflexible structure, hollow structures are formed on the inner sides of the hood-shaped sheath and the tubular sheath, and due to the adoption of the insulating sheath, the problem that the prior insulating sheath is easy to loosen and often leads to aging and cracking phenomenon to influence the normal use is solved. The insulating sheath has the characteristics of simple structure, convenient manufacture and good operational performance; and the insulating sheath is not easy to loosen when in use and has good ageing resistance and crack resistance.
Description
Technical field
The utility model relates to a kind of insulating sleeve, belongs to electric power auxiliary products technical field.
Background technology
The current insulating sleeve that uses on the power equipment transformer is made by glass-reinforced plastic material, it is a kind of solid structure, the insulating sleeve of this structure gets loose on conductive contact easily, simultaneously because operational environment is in outdoor, often expose to the weather and drench with rain, glass-reinforced plastic material can produce the season cracking phenomenon after using a period of time, causes insulation property relatively poor, and influence is normally used.
Summary of the invention
The utility model provides a kind of insulating sleeve of novelty, adopts the soft structure technology of integral type, realizes that insulating sleeve no longer gets loose and the purpose that no longer produces the season cracking phenomenon.
The technical solution adopted in the utility model is:
A kind of insulating sleeve, be made of hood-shaped cover, tubular casing, cyclic reinforcing rib structure, the tubular casing bottom is provided with hood-shaped cover, and the arranged outside of tubular casing has cyclic reinforcing rib, hood-shaped cover, tubular casing, cyclic reinforcing rib are the soft structure of integral type, and the inboard of hood-shaped cover, tubular casing is a hollow-core construction.
Cyclic reinforcing rib is plane cast structural, and is independent separately between circle and the circle, and with mode parallel to each other be arranged at from top to down on the lateral wall of tubular casing with identical spacing.
Cyclic reinforcing rib can also be a helical structure, and reeling with the form of single head or multi-head spiral line and with identical pitch is arranged on the lateral wall of tubular casing.
Described insulating sleeve is by the silica gel material monolithic manufacturing.
The utility model beneficial effect is:
Owing to adopted insulating sleeve of the present utility model, solved that existing insulating sleeve gets loose easily and often produce the season cracking phenomenon and influence the problem of normal use, that insulating sleeve of the present utility model has is simple in structure, easily manufactured, serviceability is good, be difficult in using getting loose and characteristics that anti-aging cracking performance is good.
