Structural Analysis of Low Voltage Drawer Switch Cabinet
As is well known, there are many types of switchgear, and currently the most popular one in the market is the low-voltage drawer type switchgear. Its high cost-effectiveness and safe use are highly favored by customers. To gain a thorough understanding of this equipment, first understand the overall structure of the low-voltage drawer type switchgear. Below, we will introduce it to you.
The purpose of electric control boxes, control cabinets, distribution cabinets, and distribution boxes
From the perspective of appearance and structure, the electric control cabinet and distribution cabinet (distribution board) belong to the same category, while the electric control box and distribution box belong to the same category.
Common types of substations
When it comes to substations, everyone's first reaction may be the steel reinforced structure, coupled with interwoven overhead lines. In fact, this is only the most common type of substation, with a professional name of "outdoor substation", which corresponds to indoor and semi indoor substations. Today we will learn about their differences.
How to operate the inspection and maintenance of low-voltage distribution cabinets
The distribution cabinet is a general term for the motor control center, which is used in situations where the load is relatively dispersed and the circuit is relatively small. Generally, we see that power distribution cabinets are installed in relatively concealed corners, and the maintenance of low-voltage power distribution cabinets is mainly to ensure the normal and safe operation of low-voltage power distribution cabinets. Annual general physical examination and maintenance of low-voltage distribution cabinets are required. Complete maintenance with the minimum power outage time, generally determining the owner's power outage time in advance.
What is the difference between a box type substation and a box type transformer?
What is the difference between a box type substation and a box type transformer? A transformer is a device that converts AC voltage, current, and impedance. When there is AC current in the primary coil, AC magnetic flux is generated in the iron core (or magnetic core), causing voltage (or current) to be induced in the secondary coil.
Specification of cable tray
Cable tray is a product for protecting cables. It can effectively prevent cables from being damaged by the external environment, and fundamentally extend the service life of cables. It is the full name of a rigid structural system consisting of straight sections, bends, tees, and cross sections, as well as supporting arms (arm brackets), hangers, and other components of trough, tray, or stepped types, which have tight support cables (hereinafter referred to as bridge). Today, let's talk about the specifications and models of cable tray!
