Abstract
The utility model discloses a telescopic insulating barrel, which is partitioned into an inner-layer insulating barrel and an outer-layer insulating barrel, wherein the inner-layer insulating barrel and the outer-layer insulating barrel are connected through a bracing bar and slide relatively; the inner-layer insulating barrel and the outer-layer insulating barrel are overlapped partially; the bracing bar consists of two parts which are fixed on the inner-layer insulating barrel and the outer-layer insulating barrel respectively; one part of the bracing bar has a convex structure, and the other part of the bracing bar has a concave structure; the two parts slide relatively in a matching way; the two parts of the bracing bar have wedged structure with certain gradients; the gradients are gradients along the thickness direction of the bracing bar or along the width direction of the bracing bar. The telescopic insulating barrel has the advantages of simple structure, convenience in adjustment and installation of electrical components, and variable length.
Description
Technical field
the utility model belongs to transformer manufacture technology, is specifically related to a kind of telescopic insulating cylinder.
Background technology
For effectively reducing the size of transformer and assembly thereof, guarantee safe and reliable insulation distance, factory often adopts and installs insulating cylinder outward additional at high voltage live part, conventionally the length of insulating cylinder is fixed, general 300～the 500mm of insulating cylinder diameter, for guaranteeing insulation distance, the installation site of live part should be greater than 400mm apart from insulating cylinder end in addition, because transformer inner space is less, so the installation of live part is more difficult.
Summary of the invention
Technical problem to be solved in the utility model is: solve the problem that above-mentioned prior art exists, and a kind of simple in structure, easy to adjust, variable-length is provided, is convenient to the telescopic insulating cylinder that live part is installed.
The technical solution adopted in the utility model is:
An insulating cylinder, is divided into primary insulation cylinder and outer layer insulation cylinder, between primary insulation cylinder and outer layer insulation cylinder, by stay, connects, and relative sliding, primary insulation cylinder and outer layer insulation cylinder overlap.
In technique scheme, described stay is comprised of two parts, is separately fixed on primary insulation cylinder and outer layer insulation cylinder.
In technique scheme, described stay two parts, a part is convex structure, and another part is concave structure, and two parts coordinate relative sliding.
In technique scheme, two parts of described stay, all, for being with acclive wedge structure, the described gradient is the gradient of stay thickness direction, or is the gradient of stay Width.
The utility model provide a kind of simple in structure, easy for installation, be convenient to the telescopic insulating cylinder that live part is installed, reduced installation labour intensity, improved installation effectiveness.The mounting means of insulating cylinder is constant, and original one deck insulating cylinder changes into inside and outside two-layer, and centre is supported with insulating stay.Stay adopts convex-concave wedge-like engagement structure, and convex stay and spill stay are separately fixed on ectonexine insulating cylinder, and convex stay and spill stay matched in clearance, make insulating cylinder have different collapsing lengths.The utlity model has simple in structure, easily processing, cost is low, remove and install conveniently, protect the advantages such as reliable, greatly reduces labour intensity is installed, and improves installation effectiveness.

Embodiment
Referring to accompanying drawing, telescopic insulating cylinder of the present utility model, one deck insulating cylinder of the regular length of original technology is changed into two-layer insulating cylinder, be divided into inside and outside two-layer, centre has stay to support, and two-layer insulating cylinder overlaps, and inside and outside insulating cylinder can relative sliding, realize the flexible of insulating cylinder, location and self-locking.
Stay between above-mentioned ectonexine insulating cylinder is comprised of two parts, is separately fixed on ectonexine insulating cylinder;
Stay between above-mentioned ectonexine insulating cylinder, is divided into two parts, and a part adopts convex structure, and another part adopts concave structure, and two parts coordinate, and can realize ectonexine relative sliding;
Two parts of stay between above-mentioned ectonexine insulating cylinder, all for being with acclive wedge structure, the gradient can realize at the thickness direction of stay, also can realize at the Width of stay, finally can realize location and the self-locking of insulating cylinder;
The utility model can change insulating cylinder, the material of stay, thickness, width, length, the fixed form of size, the number of plies and stay and insulating cylinder according to the actual requirements.
