Abstract
The utility model relates to a dry-change connecting-type low-voltage cabinet structure, which belongs to the technical field of low-voltage power distribution. The utility model has the technical scheme that the dry-change connecting-type low-voltage cabinet structure comprises a dry-type transformer box (1), a main cabinet (6) and an auxiliary cabinet (7), wherein the dry-type transformer box (1), the main cabinet (6) and the auxiliary cabinet (7) are sequentially connected, a circuit-breaker supporting plate (4) is arranged on the main cabinet, a main-cabinet bus frame (2) is arranged below the circuit-breaker supporting plate, an auxiliary-cabinet bus frame (8) is also arranged on the auxiliary cabinet, a copper bus (5) is arranged on the main-cabinet bus frame and the auxiliary-cabinet bus frame, and the copper bus in the auxiliary cabinet is rotated to the cabinet top of the auxiliary cabinet. The dry-change connecting-type low-voltage cabinet structure has the positive effects that: the main cabinet can be directly combined with a 2500kVA dry-type transformer box with a shell, a horizontal bus of a main-cabinet outlet bus is rotated to the cabinet top from the auxiliary cabinet, the structure is reasonable structure, the rated-current requirements can be met, the safety and reliability are realized, eddy-current loss can not be caused, and local heating can not be caused.
Description
Technical field
The utility model relates to does change connecting-type low-voltage cabinet structure, belongs to the low-voltage distribution technical field.
Background technology
At present, the existing low-voltage cabinet that is connected with dry-type transformer (for example: GGD type low-voltage distribution cabinet), because cabinet intensity, insulating part specification, heating etc. are all multifactor, be difficult to accomplish that the horizontal bus rated current reaches 4000A, can not satisfy specification requirement, unreasonable structure can produce eddy current loss in addition, causes local pyrexia.
The utility model content
The purpose of this utility model provides a kind of dried change connecting-type low-voltage cabinet structure, and is rational in infrastructure, satisfies the rated current requirement, safe and reliable, solves the problems referred to above that background technology exists.
The technical solution of the utility model is:
Do and become connecting-type low-voltage cabinet structure, comprise the dry-type transformer case that connects successively, main cabinet, auxilliary cabinet, the main circuit breaker supporting plate that cashier's office in a shop is provided with, be provided with main cabinet bus frame below the circuit breaker supporting plate, auxilliary cashier's office in a shop also being provided with assisted cabinet bus frame, copper busbar is arranged on main cabinet bus frame and the auxilliary cabinet bus frame, and copper busbar goes to the cabinet top of auxilliary cabinet in auxilliary cabinet.
Be provided with some stainless girder steels in main cabinet, the auxilliary cabinet, circuit breaker supporting plate, main cabinet bus frame, auxilliary cabinet bus frame are separately positioned on separately the stainless girder steel.
Main cabinet, auxilliary cabinet shell section material are selected the C section bar for use, and copper busbar is selected the T2 copper bar for use, and every phase copper bar is 3X(125X10).Fixed insulation spare is stainless girder steel, and bus frame inner bolt is a stainless steel bolt, to guarantee can not produce eddy current loss, and can local pyrexia.
Good effect of the present utility model is: main cabinet can be directly and the dry-type transformer case and the cabinet of 2500kVA band shell, and main cabinet outlet horizontal bus goes to cabinet by auxilliary cabinet and pushes up, and is rational in infrastructure, satisfy the rated current requirement, safe and reliable, can not produce eddy current loss, can local pyrexia.
