Excuse me, when the high voltage cabinet is installed, should the base channel (10#) be placed upright or upside down? Are there any rules?
Put it upside down, the plane faces upwards, so that it is convenient for the cabinet to be placed and fixed.
This project high voltage switch cabinet model is KYN28, altogether 14 surfaces, including the breaker cabinet 9 sides, the voltage transformer cabinet 4 sides, turns over the line cabinet 1 sides.In this project, all low voltage power distribution cabinets are selected GCS type according to the design requirements, totaling 38 faces. The capacitor cabinet has 6 sides. This type of distribution cabinet is compact in structure and strong in protection.
According to the drawing requirements, the cabinet is arranged in rows, installed on the base steel, and the distribution room adopts groove 10. When making, the bent channel steel is straightened and straightened, and the base steel is prefabricated and processed according to the drawing requirements. After the foundation steel system, according to the location of the drawings, with the civil engineering to be buried.When installing basic channel steel, leveling and aligning are applied. The uneven straightness and levelness of the base channel shall be less than 1mm at the length of each metre and shall be less than 5mm at full length.The foundation channel of buried power distribution cabinet should be well grounded. According to the design requirements, the earthing flat steel is welded at both ends with the grounding grid, and the welded surface is 2 times of the width of the flat steel.
Before installation, do the following work:(1) whether the roof and floor have been completed and whether there is leakage on the roof or floor;(two) whether the interior decoration project of power distribution room and equipment room has been fully completed?;(three), various embedded parts are installed, with equipment installation conditions;(four) whether the doors and windows of the room are installed and finished;(five) whether all the other processes which can not be carried out after the installation of the equipment have been completed are completed.
Product orders should be selected two designated certification manufacturers, equipment orders are advised by the installation conditions when the equipment has arrived, after entering, should be stored in the field equipment storehouse, the party was invited to check out of the box, factory technical documents shall be complete, types and specifications should comply with the design requirements, complete accessories and spare parts. The appearance of the cabinet shall be free from damage and deformation, and the paint shall be complete and undamaged. The inner parts of the cabinet, electrical equipment and components, insulating porcelain parts shall be complete, without damage and cracks.
