Combined low-voltage switch cabinet and working method thereof

Abstract

The invention relates to a combined low-voltage switch cabinet and a working method thereof. The combined low-voltage switch cabinet is characterized by consisting of a cabinet body of the switch cabinet, an upper ventilation plate, a lower ventilation plate, a bus, an instrument, a cable and a unit room with a functional switch circuit. The working method comprises the steps of: 1) the installation of the cabinet body, 2) the selection of a circuit proposal, 3) the internal connection of the switch cabinet, 4) the external connection of the switch cabinet, 5) the running of the switch cabinet and 6) the operation of a user. The invention has the advantages of compact structure, ability of saving the volume of the cabinet body, strong seriation and universality, high breaking ability, good dynamic thermal stability, advanced and reasonable structure, economic layout of a power distribution circuit and arbitrary combination of various proposals and units; a functional unit adopts a fixed structure, thereby facilitating the safe running, facilitating the overhaul, shortening the accident power outage time and ensuring the reliable power use; an electrical appliance element can select a domestic element or an imported element arbitrarily according to the different user demands, thereby being capable of meeting the market demands to the maximum extent; furthermore, the combined low-voltage switch cabinet has beautiful appearance, high protection level, high operation continuity and reliability and convenient installation and maintenance.

Description

(1) Technical field:

[0001] The invention belongs to a low-voltage switchgear, in particular to a combined low-voltage switchgear and its working method. (two) background technology:

[0002] At present, all kinds of low-voltage switchgears on the market generally have the following shortcomings: First, the cabinet body is too large, the structure is relatively loose, and the series versatility is weak; second, the breaking capacity is low, and the dynamic and thermal stability is relatively low. The third is that the layout of the power distribution circuit is not economical and reasonable enough, and the units of various schemes cannot be combined arbitrarily according to the needs of users; the fourth is that in terms of electrical components, domestic or imported components cannot be arbitrarily selected according to the needs of users. (3) Contents of the invention:

[0003] The purpose of the present invention is to address the above problems, to provide a combined l...
