Abstract
The utility model relates to an outgoing bus support for low-voltage side of non-encapsulated dry type transformer. In its structure, bus support is fixed to high-voltage side and low-voltage side of upper yoke clamping via screw and nut, connection bus on low-voltage side (connection bus is connected with low-voltage terminal bus) is clamped via bus clip, and the bus clip is fixed to the bus support via screw rod and nut, so as to effectively integrate low-voltage terminal bus and connection bus to form bus support structure. The inventive bus support with simple structure and reasonable design can sufficiently guarantee mechanical strength and electrical strength of outgoing bus on low-voltage side, and safe, reliable and steady operation of transformer. The utility model can form series design with capacity of 100-3,150 kVA.
Description
Technical field
The utility model relates to a kind of no-encapsulated-winding dry-type transformer low-voltage side outlet bus structure that is applicable to, belong to the transformation technical field.
Background technology
No-encapsulated-winding dry-type transformer of the prior art generally be go out on advancing down or enterprising on the outlet method that goes out, connect bus directly and the low-voltage bus bar connection, and directly stretch out the transformer case top, do not need to use bus structure.Along with the further expansion of product market share, client's demand is also more and more higher, and many users having occurred, to need the low pressure outlet method be the side outlet, directly linked by the connection bus that the side extend in the low-voltage cabinet and in the low-voltage cabinet by the low-voltage terminal bus.In order to guarantee to connect the mechanical strength of bus, must there be bus structure to support the connection bus.
Summary of the invention
The purpose of this utility model is the defective at above-mentioned existence, proposes a kind of improved no-encapsulated-winding dry-type transformer low-voltage side outlet and connects the fixing bus structure structure of bus.
Technical solution of the present utility model: its structure is the high and low pressure both sides of bus structure being fixed in upper clamping piece with screw bolt and nut.Rely on bus clip that low-pressure side is connected bus (connecting bus and low-voltage terminal bus connects) and clamp, bus clip is fixed on the bus structure with screw rod and nut.So just, connect bus and be unified into an integral body, formed the bus structure structure effectively the low-voltage terminal bus.
Advantage of the present utility model: realize that by this structure step down side is the bus structure structure that side goes out bus.This process structure is simple, and is reasonable in design, tool intensity and electrical strength when having guaranteed fully that low-pressure side goes out the machine of bus, the operation that transformer can be safe, reliable, stable.The utility model can form the Series Design of 100～3150kVA capacity.
Description of drawings
Accompanying drawing 1 is an example structure schematic diagram of the present utility model.
In the accompanying drawing 1 is bus clip, the 2nd, and screw rod, 3 is first nuts, the 4th, and bus structure, the 5th, bolt, 6 are second nuts, the 7th, upper clamping piece, the 8th, and low-voltage terminal bus, the 9th connects bus.
Embodiment
Contrast accompanying drawing, its structure are the high and low pressure both sides of bus structure 4 usefulness bolts 5 and second nut 6 being fixed in upper clamping piece 7.Rely on bus clip 1 that low-pressure side is connected bus 9 and clamp, described connection bus 9 and low-voltage terminal bus 8 connect, and the screw rod 2 and first nut 3 are fixed in bus clip 1 on the bus structure 4.So just, connect bus and be unified into an integral body, formed the bus structure structure effectively the low-voltage terminal bus.
During making, bus structure 4 usefulness bolts 5 and nut 6 are fixed in the high and low pressure both sides of upper clamping piece 7.Rely on bus clip 1 that low-pressure side is connected bus 9 (connecting bus 9 and 8 connections of low-voltage terminal bus) and clamp, bus clip 1 is fixed on the bus structure 4 with screw rod 2 and nut 3.So just, connect bus and be unified into an integral body, formed the bus structure structure effectively the low-voltage terminal bus.
