In everyday life, as a general human being, there are few opportunities to know and access low-pressure distribution cabinets, and non-professionals do not know much about what this is, whereas in practice it is common in many industries. The paper below provides a brief introduction to his rationale in several respects。
What is it
Low-voltage distribution cabinets are suitable for use in heavy industrial industries such as power plants, buildings, petrochemicals, smelting, etc., for transmission, distribution and conversion to enterprises, and are products listed in the 3c certified mandatory certified product catalogue。
02 conditions for use
There are environmental requirements for the use of low-pressure distribution cabinets to keep ambient air temperatures below 40 degrees and below 5 degrees and to ensure that the average temperature does not exceed 35 degrees within 24 hours. There are also requirements for air, which require cleaner air, no dust particles, not adapted to high-temperature, not more than 50 per cent humidity at 40 degrees and above, and a slightly higher humidity at lower temperatures, generally below 2,000 metres above sea level for the applicable area。
03 working principles
Low-voltage distribution cabinets are arranged in an orderly sequence of switches, assistive equipment, monitoring meters, electrical components, which are distributed in closed metal cabinets and form low-voltage distribution units, generally with manual and automated modes to control access to very disconnected circuits。
This is an introduction to the workings of low-voltage distribution cabinets, which can be accessed by friends who need it to remind you of the conditions of installation and use, since it is closely related to the safety of electricity and equipment and cannot be taken lightly。
