一簡單介紹 工厂的每个車間內,都必須有低压配电綫路,用以对車間低压用电設备配电。配电綫路的形式,一般有放射式、环鏈式和树干式等,按配电次序又可分为:一次配电綫、二次配电綫和分支綫等。对于車間的一次配电綫路,最經济而又方便的形式是变压器——干綫組系統,这是目前所广泛采用的系統。而二次配电綫路則大致可分为下列兩种形式: 1.采用插接式母綫,架設于專用的支柱上,或悬挂于不低于1.2公尺的高度上,然后再經保护槽或鋼管引支綫至机床等用电設备。
A brief introduction Every plant in the factory must have a low-voltage distribution circuit to distribute power to low-voltage electrical equipment in the workshop. In the form of distribution lines, there are generally radial, chain-linked, trunk-type, etc., which can be divided into primary distribution lines, secondary distribution lines, and branch lines according to the distribution order. For the primary distribution line of the workshop, the most economical and convenient form is the transformer—the trunk line system, which is currently widely used. The secondary distribution lines can be roughly divided into the following two forms: 1. Using plug-in bus bars, set up on dedicated pillars, or hung at a height of not less than 1.2 meters, and then go through the protection slot. Or pipe extensions to machine tools and other electrical equipment.
