Oct 19, 2018

Low-voltage switchgear is suitable for power transmission, power, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries, as power transmission, distribution and power conversion.

 

Use Conditions of low voltage switchgear

1. The ambient air temperature shall not exceed +40 ° C, not lower than -5 ° C, and its average temperature shall not exceed +35 ° C within 24 h.

2. The air is clean. When the maximum temperature is +40 °C, the relative humidity should not exceed 50%. At lower temperatures, a larger relative humidity is allowed.

3. Pollution level 3.

4. The altitude of the installation site shall not exceed 2000m.

5. Special use conditions, negotiate separately when ordering.

 

(1) fixed type

It can satisfy the position that each electrical component is reliably fixed in the cabinet. The shape of the cabinet is generally a cube, such as a screen type, a box type, etc., and a prismatic body such as a table top. This type of cabinet has a single row and is also arranged.


(2) Withdraw

The draw-out type consists of a fixed cabinet and a movable device part equipped with main electrical components such as switches. The movable part is light to change when moving, and the positioning is reliable after moving in, and the drawers of the same type and specification can be reliably exchanged and extracted. The method of processing the cabinet part in the formula is basically similar to that of the fixed cabinet. However, due to the interchange requirements, the accuracy of the cabinet must be improved, and the relevant part of the structure should have sufficient adjustment. As for the movable part, it must be replaced and the main components must be reliably loaded, so it must be higher. The mechanical strength and high precision, and the relevant part must have sufficient adjustment.
