Abstract

The utility model discloses a bearing structure for a phase-isolated bus with a long vertical section, which comprises a bus shell, a bus conductor, cross arm shells, cross arm conductors and sealing covers. The bus shell is vertically arranged, the bus conductor is mounted in the bus shell, the cross arm shells are symmetrically transversally disposed on two radial sides of the bus shell and communicated with the same, the sealing covers are fixedly connected with ports of the outer sides of the cross arm shells, the cross arm conductors transversally penetrate through the bus conductor and vertically fixedly connected with the bus conductor, and two ends of each cross arm conductor are supported in the corresponding cross arm outer shell by at least one insulator component group. The bearing structure is simple, safe and reliable, when the long vertical section of the phase-isolated bus is longer, the weight of the bus conductor is mainly carried by the cross arm conductors, and the insulators only bear light weight, thereby eliminating bearing hidden risks during movable stable running of the phase-isolated bus and being favorable for safe running of an integral phase-isolated bus system.

Description

Long vertical section phaseisolated bus heavy burden structure

Technical field

The utility model relates to a kind of phaseisolated bus, and especially a kind of supporting construction of long vertical section phaseisolated bus belongs to the transmission facility technical field.

Background technology

Phaseisolated bus generally includes shell and supports in the enclosure bus-bars conductor by insulator assembly; in the large-scale power station engineering; run into the setting up of long vertical section phaseisolated bus of longer distance through regular meeting; when the phaseisolated bus vertical section was longer, bus-bars conductor was very heavy, and its overall weight is all born by insulator assembly; cause insulator to damage easily; insulator is short useful life, and it is unreliable to support, thereby influences the reliability service of whole bus-bar system.At present, solve the heavy burden problem of long vertical section phaseisolated bus, the main mode that adopts the top of hanging oneself down, this mode are applicable to that the short phaseisolated bus of vertical range sets up, insulator technology is had relatively high expectations, and also complex structure, maintenance difficult.The insulator of lower support bus-bars conductor weight on also damaging easily when moving stablizing taken place, overall structure is unfavorable for the safe and reliable operation of phaseisolated bus.

Summary of the invention

The purpose of this utility model provides the phaseisolated bus heavy burden structure that a kind of simple in structure, heavy burden ability is strong, be suitable for the random length vertical range.

The utility model is achieved by the following technical programs:

A kind of long vertical section phaseisolated bus heavy burden structure, comprise vertically disposed bus shell, be installed in the bus-bars conductor in the bus shell, also comprise cross-arm shell, cross-arm conductor, capping, described cross-arm shell is horizontal symmetrically in bus shell both sides radially, connects with bus shell; Described capping is fixedlyed connected with cross-arm shell outside port, and described cross-arm conductor passes across bus-bars conductor, is connected with the bus-bars conductor vertical fixing, and cross-arm conductor two ends are supported in the cross-arm shell by at least one group of insulator assembly respectively.

The purpose of this utility model can also further realize by following technical measures.

Aforesaid long vertical section phaseisolated bus heavy burden structure, wherein said cross-arm conductor two ends port welding shutoff.

The long vertical section heavy burden of aforesaid phaseisolated bus structure, the cross section of wherein said cross-arm shell and cross-arm conductor are circle or rectangle or polygon.

The utility model is simple in structure, and is safe and reliable; When the phaseisolated bus vertical section was longer, the weight of bus inner conductor was mainly born by the cross-arm conductor, and insulator only bears very little weight, insulator is not fragile, support reliably, eliminated the heavy burden hidden danger when bus moves stable operation, help the safe operation of whole bus-bar system.The utility model heavy burden ability is strong, is suitable for the phaseisolated bus of any vertical height, and the stack effect when dispelling the heat to eliminating vertical bus also has positive effect.

Advantage of the present utility model and characteristics will illustrate by the non-limitative illustration of following preferred embodiment and explain that these embodiment only provide as an example with reference to accompanying drawing.
