Description

A kind of concentration bus duct

Technical field

The utility model belongs to the electrical power trans mission/distribution system technical field, is specifically related to a kind of concentration bus duct.

Background technology

Common concentration bus duct comprises the bus duct metal shell, insulating cell, heterogeneous bus-bars conductor and coated insulation layer, its metal shell is generally steel or aluminum, comprise up and down two cover plates and about two side plates, assembling mode is generally punching on cover plate and side plate in advance, utilize fastener bolt or screw mount then, the major defect of this structure is: 1, the metal shell part is more relatively, amount to the four-piece type structure, its side plate and cover plate need symmetric arrangement, and required precision height in process and assemble hole around it, conventional production and processing technology is difficult for guaranteeing that production efficiency is low; 2, adopt conventional bolt or the fastening fit of screw between the cover plate of metal shell and the side plate, there is the fit-up gap in its assembling junction, reduced the sealing protection performance of bus duct metal shell thus, limited bus duct and under the relative rugged environment of condition such as needs are dustproof, moistureproof, anticorrosion, used; 3, the conventional bolts assemblies mode mode that as will improving sealing, adopts the pad sealing gasket or break fluid sealant, but the thermal diffusivity of general sealing gasket or fluid sealant is all relatively poor, and easily wear out and become fragile, ftracture or come off, therefore not only sealing reliability can not guarantee, also reduced the thermal diffusivity and the current capacity of bus, bus duct is reduced useful life.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, easy to assembly, tight concentration bus duct of sealing.

The utility model concentration bus duct comprises bus duct shell, heterogeneous bus-bars conductor, coated insulation layer, insulating cell, corrugated heat-resisting elastic packing rubber cushion, adapter plate and end socket, described bus duct shell comprises semiclosed cell body and U type side plate, described semiclosed cell body is a monolithic construction, its cross section is the I-shaped shape, its upper and lower is the outside U type cover plate of opening, and the middle part is a riser; Described U type side plate is put between the U type cover plate of the upper and lower of semiclosed cell body in the mode of opening outside side, and on the side of U type side plate and the semiclosed cell body, between the U type cover plate of bottom is interference fit, on the semiclosed cell body, the face that is fitted to each other of the side of the cover plate of bottom and U type side plate is corrugated fitting surface, between the U type cover plate on the top of the side of U type side plate and semiclosed cell body and and the U type cover plate of the bottom of semiclosed cell body between all sticking corrugated heat-resisting elastic packing rubber cushion is housed, on the semiclosed cell body, the respective side of the U type cover plate of bottom and U type side plate is passed through riveted and fixed; Described heterogeneous bus-bars conductor coated outside has the coated insulation layer, put in the bus duct shell, expose outside the bus duct shell at the two ends of its length direction, its above and below and two sides are close on the riser, U type side plate of the U type cover plate of upper and lower part of semiclosed cell body and semiclosed cell body, and all sticking insulating cell that is equipped with between the U type cover plate of the upper and lower part of its above and below and semiclosed cell body; End socket is put at the two ends of the U of the upper and lower part of semiclosed cell body type cover plate, and uses bolt; Adapter plate is put at the two ends of bus duct shell, the outside of heterogeneous bus-bars conductor, is fixed by bolts on the end socket.

The beneficial effects of the utility model: change the four-piece type splicing structure of traditional concentration bus duct metal shell into the two-piece type structure, reduced fitting surface quantity, thereby reduced manufacturing procedure, improved production efficiency; The semiclosed cell body of bus duct shell and U type side plate junction are interference fit, and change the bolts assemblies mode into the riveted joint assembly technology, make semiclosed cell body and U type side plate all not need the punching out pilot hole, avoided the bus duct casing deformation that produces because of punching, the face that is fitted to each other of semiclosed cell body and U type side plate is corrugated fitting surface simultaneously, and sticking in the two junction corrugated heat-resisting elastic packing rubber cushion is housed, after riveted and fixed, thoroughly eliminate the slit of the portion that is fitted to each other, improved the sealing protection performance and the useful life of bus duct shell.
