Embodiment Construction
[0025] The embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings; it should be noted that the embodiments are illustrative, not restrictive, and cannot limit the protection scope of the present invention.
[0026] A compact low-voltage power distribution cabinet, including a housing, a busbar system and a circuit breaker. The middle and lower part of the housing is provided with a mounting beam a, and the upper part of the housing is provided with a mounting beam b. The front and rear busbar systems and circuit breakers are placed back to back. The A-phase busbar (1), B-phase busbar (2) and C-phase busbar (3) in each group of busbar systems are stacked vertically to the busbar clamps (4) and fixed by the busbar clamps (4), and the busbar clamps ( 4) Fasten the mounting plate (5) with hexagon socket head bolts, and fix the mounting plate (5) to the mounting beam a (11) on the low-voltage power distribution cabinet sh...

The invention relates to a compact low voltage power distribution cabinet. The compact low voltage power distribution cabinet comprises a housing, two busbar systems, and circuit breakers. The front and back two busbar systems and the circuit breakers are in a back-to-back arrangement. The A-phase busbar, the B-phase busbar, and the C-phase busbar of each of the busbar systems are vertical to a busbar clamp, and are arranged in a stacked way, and the busbar clamps are fixedly connected with installation plates. The installation plates are, from top to bottom, sequentially provided with a plurality of plugging type busbar connectors, and one side of each of the plugging type busbar connectors is connected with the corresponding circuit breaker, and the other side is connected with the corresponding side of the stacked busbars in an inserted manner. Upper port busbars of knife switches are connected with main busbars by bolts, and the lower ports are connected with the A-phase busbars, the B-phase busbars, and the C-phase busbars, which are in a stacked arrangement, by the busbars to form power distribution systems. The compact low voltage power distribution cabinet is advantageous in that the compact low voltage power distribution cabinet project is used to realize the standardization, integration, and modularization installation way of the low voltage busbar power distribution system, and the conventional modes of the conventional low voltage power distribution cabinets such as busbar perforating and bending installation are changed completely, and after use, backup loads can be increased or reduced anytime, and therefore installation efficiency is improved, and production costs are reduced.
Description
technical field [0001] The invention relates to the technical field of electric equipment, in particular to a compact low-voltage power distribution cabinet. Background technique [0002] As an important part of energy distribution, the busbar system is gradually developing towards a simple, safe and compact structure. The bus bar in the traditional power distribution cabinet is installed horizontally under the top of the power distribution cabinet, and the switches are installed vertically under the bus bar, which are placed in order from left to right. Taking a feeder cabinet as an example, the busbar adopts the traditional drilling and bending installation process, which is cumbersome and time-consuming. When the housing space is certain, the number of circuit breakers installed inside will be greatly limited, especially in the case of a large number of low-voltage circuit outputs. It is difficult to add circuit breakers on site, and sufficient backup must be ensured be...
