What Precautions Should Be Taken For The Operation And Maintenance Of The 10kV Box Substation

What precautions should be taken for the operation and maintenance of the 10kV box substation

1. Strengthen the lightning protection measures for 10kV box transformer enclosure distribution lines, install lightning arresters for protection, and ensure that the protection range of the lightning arresters can cover the entire area of the box transformer enclosure. At the fixed position of the insulation guide, thicken the insulation treatment to enhance the ability of the distribution line to withstand lightning strikes and insulation line disconnection faults, At the same time, metal zinc oxide lightning arresters should be installed at the connection positions of the outgoing cables and isolation switches to prevent lightning from entering the transformer through the cables. In addition, power lightning arresters should be installed at the power inlet and outlet of communication and protection equipment. Finally, shielded cables must be used for all incoming and outgoing cables in the box transformer casing, and surge suppressors should be installed at the control and communication interface positions.

2. Regular maintenance and upkeep must be carried out on the distribution lines and substation equipment of the 10kV box transformer casing to promptly detect any internal abnormalities. At the same time, in unmanned situations, temperature and smoke alarms should be installed inside, and the alarm signals should be directly connected to the monitoring center to achieve timely detection and handling of faults and hidden dangers.

3. Strengthen the heat dissipation of the 10kV box transformer casing. Efficient heat dissipation is an important prerequisite for ensuring the safe and stable operation of internal equipment. Firstly, the box itself should have good heat generation performance and adopt a body heat dissipation design. The base should be hollow out, and the space below the foundation should be lower than the very positive and negative zero ground. On the one hand, it can avoid the surface temperature, and on the other hand, it can ensure that hot air can be discharged from the heat dissipation hole and cool air can be sucked in from the bottom.

In order to ensure the safe and efficient operation of the 10kV box transformer casing, as a power supply unit, it is necessary to strengthen its management and maintenance. In daily work, it is necessary to strengthen the implementation of operation and maintenance work, effectively clarify the responsibilities of operation and maintenance personnel, closely combine the operating characteristics of the 10kV box transformer casing with the actual operation needs, and effectively strengthen the analysis of safety hazards, and take effective measures, laying the foundation for the efficient operation of the entire equipment
