Abstract

The utility model discloses a laminated bus which is a connection bus of elements in a low-voltage electric cabinet. The laminated bus comprises two or three bus layers, wherein the bus layers are partially overlapped with each other, two ends of each bus layer are respectively provided with an L-type bending, and the L-type bending is provided with a hole for connecting the elements, the laminated part of the bus layers is provided with epoxy phenolic glass cloth insulating boards, the bus layers and the epoxy phenolic glass cloth insulation boards are bonded and fixed, the laminated bus is formed by winding a glass fiber belt outside a three-phase bus and the epoxy phenolic glass cloth insulation boards to form an entire body, and disposing a spraying plastics layer at the surface. The laminated bus is easy to maintain and beautiful in appearance, with which assembly difficulty is reduced, assemble and disassemble are facilitated.

Description

A kind of stacked bus

Technical field

The novel connection bus that relates to components and parts in a kind of low-pressure electric cabinet of the present invention.

Background technology

At present, in low-pressure electric cabinet, the connection of components and parts is to adopt bus or cable.The common quantity of tradition bus is many, shape kind is many, be not easy to mounting or dismounting and safeguard, and cabling is not attractive in appearance.

Summary of the invention

In order to solve, traditional bus requirement is many, mounting process is complicated, be not easy to the problem safeguarded, the invention provides a kind of stacked bus, and this stacked bus is is not only installed and removed conveniently, and attractive in appearance.

Technical scheme of the present invention is: a kind of stacked bus, be characterised in that, comprise two layers or three layers of bus, the mutual part of bus is stacked, and respectively there is a L-type bending at each phase bus two ends, and bending part design is porose with Connection Element, bus laminated portions has epoxy phenolic glass cloth insulation board between bus, bus and epoxy phenol aldehyde glass cloth laminated board are adhesively fixed, and stacked bus is bundled into one by being wound around glass tape by three-phase bus and epoxy phenol aldehyde glass cloth laminated board, and there is plastic-blasting layer on surface.

The invention has the beneficial effects as follows, reduced the difficulty of bus assembling, install and remove conveniently, be easy to maintenance, good looking appearance.
