How to distinguish the one or two grade distribution box from the distribution box at the site
In the construction of the construction site or in the installation of electric power engineering, we often say the first class distribution box, the two level distribution box. So how do you distinguish it from an electrical engineer? The Guizhou distribution box manufacturer answers how the distribution box in the construction site distinguishes the one or two grade distribution box.
The primary distribution box refers to the general distribution box. Generally, it is located in the middle point of the distribution room to control all the power supply in the construction site, and is set in the area near the power supply. The power supply is connected to the cable line drawn from the low voltage side of the transformer, and the current transformer, active watt hour meter, reactive watt hour meter, ammeter, voltmeter, main switch and sub switch are installed. The switch in the general distribution box should be used by the knife melt switch (or the leakage protection switch). Introduction, lead wire wear and waterproof tube bending. The construction electricity primary distribution cabinet is used for the construction site construction and electricity. It is specially designed for the special conditions of the construction site, and is in line with the construction sector's standards for the construction electricity consumption.
Temporary electric power distribution box on site
Two level distribution box, is the distribution box, also called the sub box, generally responsible for a power supply area. The application of electricity for construction site construction is specially designed for the special construction site. It is in line with the standard of construction electricity specification for construction department. The whole set of products can make up the three level protection system for the complete construction electricity use, and achieve the purpose of one protection. The two class box is designed with internal and external doors, and the exterior is sprayed. It is safe and beautiful, and the roof of the rain proof box is suitable for the field work.
Guizhou Sen Da Electric Electric Electric Co., Ltd., box type transformer, high and low voltage switch cabinet, create the first brand of central China Electric complete set. Summarize this article: from the low voltage terminal of transformer to the first distribution box connected to the branch, it is called the first class distribution box, which is connected from the first class distribution box to the next class distribution box, it is called the two stage distribution box. At this time, if the branch of the two grade line is connected to a distribution box, it is also called the two level distribution box, not called the grade three distribution box. From the two level distribution box to the next level of the distribution box, called the three level distribution box.
