Production Technical Requirements And Installation Methods Of Distribution Boxes
The distribution box generally assembles switchgear, measuring instruments, protective electrical appliances and auxiliary equipment in a closed or semi-enclosed metal cabinet or on a screen to form a low-voltage distribution box. The distribution box needs to be developed in accordance with certain technical requirements during production, and the performance, quality and technology of the distribution box can be guaranteed. Today, the editor of Hangzhou Huayi Electric, a manufacturer of distribution boxes, will specifically introduce what are the technical requirements for the production of distribution boxes? What is the installation method of distribution boxes? I hope it can help everyone.
1. Mechanical and appearance requirements of distribution boxes:
High And Low Voltage Distribution Cabinets The outer coating color should be electrostatically sprayed according to the requirements of Party A. The coating should be firmly attached, uniform in color, without wrinkles, peeling, spots, leaks and other undesirable phenomena. There is no obvious color difference and reflection when observed at a distance of 1 meter. The surface is flat and clean, without pits, scratches and other damage. Other coated parts used in the box should also be guaranteed to be free of peeling, spots, leaks, rust and other undesirable phenomena, and the appearance quality should meet the same requirements as above. The box should be clean. Except for the information and spare parts provided to the user and the accessories required by other national standards, there should be no debris, dust, etc. in the box.
2. Requirements for electrical performance:
The main switch of the distribution box should be connected to the sub-switch with a copper bar (no bare conductor) and meet the requirements of the standard acceptance. It cannot be connected with copper wire; the cross-section of the outgoing wire of the main switch cannot be less than the cross-section of the incoming wire; the loop marking should be typed with a plastic strip and fixed firmly.
Installation method of distribution box:
Before installation, the distribution box has high requirements for the installation site, lines, etc. The distribution box is divided into open-type distribution box and concealed distribution box. The following is the steps for the distribution box installation by the distribution box manufacturer.
Before installing the distribution box, you should choose a good location according to the requirements for installing the distribution box, and the various lines should be sorted out, etc. Let's mainly talk about the installation of the open-type distribution box. The open-type distribution box is divided into open-type open-type box and concealed-type open-type box, but the installation method of the distribution box is roughly the same. To install the distribution box, you must first disassemble the distribution box and divide it into three parts: the box body, the disk core inside the box, and the box door. The next step is to install the box body, fix the iron frame in the specified position by welding, and then fix the box body on the iron frame; after installing the box body, the next step is to install the disk core inside the box, first clean up the debris in the box body, then straighten the wires, distinguish the branches and phase sequence, and mark them, and fix the disk core to the box body; finally, install the box cover. After the installation is completed, check for errors and then test discharge. I briefly explained the steps for installing the distribution box, and I hope it will be helpful to you.
