Abstract
The utility model discloses a high-capacity low-voltage complete set of switch cabinet. By utilizing the non-magnetic conductive property of stainless steel, the switch cabinet breaks the closed loop magnetic conductive surface, through which the original current passes, by replacing partial parts with stainless steel material, therefore, the purpose of restraining the generation of eddy current is achieved, the problem of eddy current of high-capacity low-voltage complete set of switch cabinet is effectively solved, the performance parameters of the interior electric appliances are enabled to be stable and the operation of the interior electric appliances is reliable. Besides, since a connecting bracket and a beam are additionally arranged at the joint of section bars of the cabinet body, the mechanical intensity of the entire cabinet body is improved.
Description
Technical field
The utility model relates to the low-voltage complete switch equipment technical field, specifically a kind of big capacity low pressure voltage switchgear.
Background technology
Along with the progress of society, the load of electricity consumption continues to increase, and the capacity of transformer improves constantly, and electric current constantly increases thereupon.Low-voltage complete switch cabinet electric current generally is 3200A to the maximum at present, and the 5000A electric current is seldom arranged,
And the problem of existing 5000A high-current low-voltage voltage switchgear eddy current is more serious, causes ambient temperature to raise rapidly easily, thereby reduces the electric property parameter in all directions.When thereby the cross section that electric current passed through exists closed loop magnetic conduction face to form around magnetic field, just produced eddy current, suppressed the purpose that eddy current produces, just " closed loop " must have been broken, made the magnetic conduction face discontinuous if therefore want to reach.The character of stainless steel material is magnetic conduction not, and the intensity height, can be used as the installing component of low pressure housing.
Summary of the invention
The utility model provides a kind of big capacity low pressure voltage switchgear, solves the problem that big electric current produces eddy current, makes the operation of 5000A high-current low-voltage voltage switchgear more reliable.
For achieving the above object, the technical solution of the utility model is as follows:
Include two degree of depth crossbeams (1), two rear columns (2), side stand I (3), side stand II (4), brace summer I (5), brace summer II (6), lead-in line row (8) and cabinet top main bus bar (13), it is characterized in that, two degree of depth crossbeams (1), two rear columns (2), side stand I (3) and side stand II (4) all adopt stainless steel material, the junction of fore-and-aft direction crossbeam and corresponding column is provided with little gusset (10) in the cabinet, the junction of left and right directions crossbeam and corresponding column is provided with section bar support (11) in the cabinet, is provided with cross-brace (12) between the column of fore-and-aft direction in the cabinet.
The utility model utilizes stainless not magnetic conduction character, the closed loop magnetic conduction face that primary current is passed through is that the means of stainless steel material are broken by replacing the part parts, thereby realize suppressing the purpose that eddy current produces, solved the problem of high-current low-voltage voltage switchgear eddy current effectively, make its inner electrical equipment performance parameter steady, reliable, because cabinet section bar junction is increased connection support and crossbeam, increased the mechanical strength of whole cabinet in addition.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
As shown in the figure, two degree of depth crossbeam 1 materials adopt stainless steel material, and the lead-in line row 8 that stretches out the cabinet top is blocked its magnetic conduction face, reach the purpose that suppresses eddy current; Two rear columns 2 and side stand I 3 materials adopt stainless steel material, and cabinet top main bus bar 13 is blocked its magnetic conduction face, reach the purpose that suppresses eddy current; Because of side stand II 4 and brace summer I 5 that supports busbar and brace summer II 6 form a closed loop, for blocking its magnetic conduction face, side stand II 4 materials are adopted stainless steel material, busbar I 7 of inlet wire branch and II 9 are blocked its magnetic conduction face, reach the purpose that suppresses eddy current.
The junction of fore-and-aft direction crossbeam and corresponding column is provided with little gusset 10 in the cabinet, the junction of left and right directions crossbeam and corresponding column is provided with section bar support 11 in the cabinet, be provided with cross-brace 12 between the column of fore-and-aft direction in the cabinet, strengthened the mechanical strength of cabinet.
