The daily usage precautions of container converting substation cover multiple aspects to ensure its safe and stable operation. Here are some key usage precautions. I hope the following introduction can provide users with reference.
1、 Site selection and foundation
Terrain selection: Container converting stations should be placed at higher elevations to avoid low-lying areas and prevent rainwater from entering. If high ground cannot be selected due to terrain limitations, the impact of rainwater on the substation should be reduced by constructing waterproof dams, drainage ditches, and other facilities.
Stable foundation: When pouring concrete platforms, it is necessary to ensure that there is a gap between the high and low voltage sides for the laying of cables in and out, and to ensure the stability of the foundation to prevent the substation from tilting or collapsing due to unstable foundations.
2、 Container converting substation security protection
Waterproof performance: Container conversion substations should have good waterproof performance, and waterproof sealing strips should be installed at openings such as doors and windows to ensure that rainwater cannot penetrate. At the same time, ventilation and heat dissipation facilities such as exhaust holes and louvers should be regularly inspected and cleaned to prevent internal equipment from overheating due to blockage.
Grounding and Zeroing: The grounding and zeroing of container conversion substations must be reliable, and the grounding network generally adopts the method of driving grounding piles at the four corners of the foundation and connecting them together. The grounding resistance should be measured regularly to ensure that it does not exceed the specified value.
Lightning protection device: Lightning arresters should be installed in substations to prevent damage to equipment caused by lightning. At the same time, the operation status of the lightning arrester should be regularly checked to ensure its normal operation.
3、 Daily inspection and maintenance of container converting substation
Daily inspection: Regularly inspect the container conversion substation to check whether all components are intact, whether there are any abnormal sounds or vibrations.
Electrical component maintenance: Focus on inspecting and maintaining electrical components such as circuit breakers and isolating switches to ensure their flexible operation and good contact. Timely replace aging and damaged equipment and cable connections to ensure that there is no looseness in the fastening.
Cooling system maintenance: For transformers that rely on air cooling or oil immersed air cooling, the working condition of their fans and radiators should be regularly checked to avoid excessive temperature caused by poor heat dissipation, thereby ensuring the normal operation time of the transformer is extended.
Insulation performance testing: Regularly test equipment insulation resistance and other indicators to ensure good and safe operation, and avoid leakage or other safety hazards.
4、 Requirements and Emergency Preparedness for Container Converting Substation Environment
Clean environment: No illegal stacking is allowed around the container conversion substation to ensure ventilation and operation inspection of electrical equipment.
Emergency preparedness: Develop a scientifically sound emergency plan, including emergency organization, preliminary preparation, emergency response measures, etc. During the rainy season or other special periods, it is necessary to ensure that there are sufficient personnel on duty and implement a shift duty system. Once a dangerous situation is discovered, the emergency plan should be activated immediately and emergency work should be carried out quickly according to the requirements of the plan.
In summary, the daily usage precautions for container converting substations involve multiple aspects such as site selection, safety protection, daily inspection and maintenance, as well as environmental requirements and emergency preparedness. By following these precautions, the safe and stable operation of the container conversion substation can be ensured.
