Description
Technical field
The utility model relates to the insulated support of bus in a kind of low-voltage bus bar bridge, belongs to technical field of electric equipment.
Background technology
In switchgear house, power distribution cabinet number ratio is more, in order to reduce the floor space of switchgear house, make full use of the spatial area in switchgear house, often one group of power distribution cabinet is not installed at row's straight line, power distribution cabinet may be face-to-face installation, also may be that turning is installed, this just needs to be connected together by this group power distribution cabinet with bus bridge.The connection of distribution indoor transformer and low-voltage distribution cabinet also all leans on bus bridge at present.
Existing bus bridge has intensive bus bridge and air-insulated type bus bridge.Intensive bus bridge cost is very high, obviously too high concerning cost the switchgear house of low and middle-grade community.Existing intensive bus bridge requires higher to insulating material, and cost is also higher.Air-insulated type bus bridge is the first-selection of most of user.But the insulated support that manufacturing firm selects just becomes the problem of most critical.
Common bus bridge adopts insulator to support mostly.A lot of manufacturer, in order to durable, adopts insulator supporting bus to keep flat.The bus heat radiation kept flat is slow, causes the ampacity of bus to reduce, too increases the width of bus bridge simultaneously, had certain requirement to field erected space; Some users adopt insulator to be sidelong bus at right angle setting.Which solve the ampacity problem of bus, but have ignored the side draw of bus to insulator and the stress problem of bus, the support force of insulator has just all become side draw; If insulator strength is inadequate, will cause Insulator detection, very short a period of time loses the due insulating supporting effect of insulator with regard to distortion to have caused a lot of bus bridge to be used.And adopting insulator to support, Area of bearing is smaller, can not reach the comprehensive support of bus.
Utility model content
For solving the problem, the utility model provides the insulated support of bus in a kind of low-voltage bus bar bridge, supports effective insulated support to space no requirement (NR)---bus frame.
The utility model adopts following technical proposals to be achieved:
An insulated support for bus in low-voltage bus bar bridge, it is characterized in that being to comprise the first bus frame, described first bus frame comprises phase sequence hole; The first described bus frame is connected with bus bridge; The bus in described bus bridge is placed in described phase sequence hole; The first described bus frame is connected by screw bolt and nut with described bus bridge.
Further technical scheme is, described the first bus frame (1) can adopt three-phase four-wire system bus frame, and described three-phase four-wire system bus frame can be replaced the second bus frame (5), and described the second bus frame (5) can adopt three-phase three-wire system bus frame.
Further technical scheme is, described bus and described phase sequence hole match.
Further technical scheme is, size and the described bus of described first bus frame match.
Further technical scheme is, the size in described phase sequence hole and the thickness of described bus match.
The beneficial effects of the utility model are: the bus arranged orthogonal in (1) bus bridge enters in the corresponding phase sequence hole of bus frame, without the need to considering the ampacity increasing bus bridge; (2) to the no requirement (NR) of in-site installation space; (3) four faces of bus all contact with bus frame, and Area of bearing is larger, and support effect is good; (4) bus only has vertical gravity effect to the bottom of bus frame, and can not produce the active forces such as other pulling force, the useful life of bus frame is extended.
