In progress Sichuan electric power equipment construction What points do we need to pay attention to? The following small make-up of some common precautions, take a look at it!

1. The electrical equipment shall have enough electrical clearance and creepage distance to ensure safe and reliable operation of the equipment.

2. All electrical components shall be able to be disassembled and replaced separately without affecting the fixation of other components and wire bundles.

3. The heating element should be installed in the place with good heat dissipation. The connection between the two heating elements should be heat-resistant wire or bare copper wire with porcelain tube.

4. The installation of electric heating elements such as resistors should be generally installed above the box. The installation direction and location should consider the advantages of heat dissipation and minimize the thermal impact on other components.

5. The layout of electronic components in the cabinet shall be far away from the main circuit, switching power supply and transformer as far as possible, and shall not be placed directly or close to the convection direction of other heating elements in the cabinet.

6. The arrangement of master operating and setting electrical components should avoid the possibility of misoperation or change of action value due to accidental touch of its handle and button. The setting device should be locked with double nuts and sealed with red paint after setting to avoid moving.

7. Fuses and parts that are easy to be damaged in use and need to be adjusted and reset occasionally shall be accessible without removing other components, so as to facilitate replacement and adjustment.

8. For fuse with fuse indicator, the indicator shall be installed on the side convenient for observation.

9. When the porcelain fuse is installed on the metal base plate, its base should be padded with soft insulating pad.

10. When the low-voltage circuit breaker and fuse are used together, the fuse shall be installed at the power supply side.

11. Strong and weak current terminals shall be arranged separately; in case of difficulties, obvious signs shall be provided and empty terminals shall be set for separation or partition board for strengthening insulation.

12. The terminal shall have serial number, and the terminal strip shall be easy to replace and connect; the height from the ground should be greater than 350mm.

13. Shock absorber shall be added to the electrical appliances with anti shock requirements, and anti loose measures shall be taken for the fastening bolts.

14. Fasteners shall be galvanized products, bolt specifications shall be selected properly, and electrical appliances shall be fixed firmly and stably.

15. The end of new blanking guide rail shall be cut with inclined opening to prevent accidents during operation.

16. The trunking should be flat, without distortion and deformation, the inner wall should be smooth, without burr and good toughness. The common market trunking is poor. It is recommended to use Japanese made trunking or other imported trunking

17. The connection of trunking shall be continuous. The fixed points of each section of trunking shall not be less than two. There should be fixed points at corners, branches and ends, which should be fixed close to the wall

18. The slot interface shall be straight and tight, and the slot cover shall be complete, flat and free of warping angle.

19. For screws or other fasteners used to fix or connect the trunking, such as rivets for daily trunking, their ends shall be smoothly connected with the inner surface of trunking.

20. The trunking shall be laid in a straight and neat manner, with the allowable horizontal or vertical deviation of 2 ‰ of its length, and the allowable deviation of the total length of the raceway shall be 20 mm. When installed in parallel, the groove cover shall be easy to open.
