The high-voltage bus comprises a conductor, an upper insulating sheath, a lower insulating sheath, an upper inner ring, a lower inner ring and an outer sleeve, wherein the upper inner ring and the lower inner ring are sleeved in the middle of the conductor, the distance t between the upper inner ring and the lower inner ring ranges from 80mm to 150mm, the outer sleeve is sleeved on the upper inner ring and the lower inner ring, the outer sleeve is in threaded connected with the upper inner ring and the lower inner ring, the upper insulating sheath and the lower insulating sheath are sleeved on the conductor, the upper insulating sheath is arranged on the upper end of the upper inner ring, and the lower insulating sheath is arrange don the lower end of the lower inner ring. The high-voltage bus for the distribution transformer table is applied to a bus bridge of the distribution transformer table.
Description
Technical field
The utility model relates to a kind of high voltage bus, is specifically related to a kind of distribution transformer platform high voltage bus.
Background technology
The high voltage bus design total length that distribution transformer platform is used is 3200mm, and original high voltage bus is plain conductor, and during plain conductor, directly hanging earthing conductor on plain conductor is realized the measure of ground wire resist technology.Behind the existing distribution transformer platform insulating; the outer surface of the high voltage bus that distribution transformer platform is used is provided with insulating protective layer; when the distribution transformer platform power failure operation is done the measure of ground wire resist technology; need to be provided with the high voltage bus hanging earthing conductor of insulating protective layer; because the high voltage bus that existing distribution transformer platform is used is provided with insulating protective layer (being the not exposed position that articulates on the high voltage bus); generally be in high pressure fall insurance lower end; the bus end hanging earthing conductor of transformer high-voltage terminal or lightning arrester; these articulate the position and exist with the charging equipment safe distance inadequate; easily break equipment; operating personnel's personal safety articulates the not firm problem such as easily come off in position, so that can not get ensureing.
The utility model content
The purpose of this utility model is to be provided with insulating protective layer for the outer surface that solves the high voltage bus that existing distribution transformer platform uses; when the distribution transformer platform power failure operation is done the measure of ground wire resist technology; the problem that does not have plain conductor that can earth connection on the high voltage bus, the high voltage bus that provides a kind of distribution transformer platform to use.
High voltage bus of the present utility model comprises wire, upper insulation sheath, lower insulation sheath, upper inner ring, lower inner ring and overcoat, described upper inner ring, lower inner ring all are sleeved on the middle part of wire, distance between described upper inner ring and the described lower inner ring is 80mm～150mm, described coat suit is on upper inner ring and lower inner ring, and overcoat is with upper inner ring and lower inner ring and is threaded, described upper insulation sheath and lower insulation sheath all are sleeved on the wire, and upper insulation sheath is positioned at the upper end of upper inner ring, and lower insulation sheath is positioned at the lower end of lower inner ring.
The utlity model has following beneficial effect: in appearance design upper inner ring, lower inner ring and the overcoat of high voltage bus, has one section plain conductor so that be provided with on the high voltage bus of insulating protective layer, when the needs high-voltage busbar ground wire, can expose this plain conductor by the dismounting overcoat, realize the direct earth connection of plain conductor; When not needing high-voltage busbar ground wire, with overcoat and upper inner ring and lower inner ring installation, the plain conductor insulation is covered, reduce external factor and bring hidden danger to equipment safety operation, again can be so that operating personnel's unsafe factor be reduced to zero, thus operating personnel's personal safety ensured.The utility model can recover the high voltage bus insulation behind the hanging earthing conductor again so that when the distribution transformer platform power failure operation is done the measure of ground wire resist technology, the plain conductor position of hanging earthing conductor is arranged namely on the high-voltage insulated bus.
