Container Type Substation, as a complete set of transformer and distribution equipment that organically combines functions such as high voltage receiving, transformer voltage reduction, and low voltage distribution, is widely used in urban power grids and industrial and mining enterprises. To ensure its safe and stable operation, the following are maintenance precautions for box type substations.
1、 Container Type Substation Appearance and Structure Inspection
Box inspection: Regularly inspect the appearance of the box, including whether the door panels, locks, hinges, etc. are intact, whether there is deformation, rust, or damage. Ensure that the box is well sealed to prevent dust, moisture, and other contaminants from entering the box and affecting equipment performance.
Foundation and Support: Check whether the foundation of the box type substation is stable, and whether there are any sinking, tilting, or other phenomena. Ensure that the supporting structure is not damaged or deformed, and the connection is firm.
2、 Container Type Substation Electrical System Maintenance
High voltage side equipment: Regularly check the operating status of high-voltage switchgear, circuit breakers, isolating switches and other equipment to ensure flexible operation and good contact. Check the insulation performance of high-voltage cables to prevent aging, damage, short circuits or leakage. Regularly conduct preventive tests on high-voltage equipment, such as withstand voltage tests, insulation resistance tests, etc.
Transformer: Regularly check the oil level, oil temperature, oil color and other parameters of the transformer to ensure its normal operation. Check if the cooling system of the transformer is working properly to prevent overheating. Regularly conduct insulation resistance tests, DC resistance tests, etc. on transformers to evaluate their performance.
Low voltage side equipment: Check if the wiring of low-voltage switchgear, distribution panels, and other equipment is secure, and if there is any looseness or overheating. Regularly check the insulation performance of low-voltage cables to ensure power supply safety. Check if the protective device on the low voltage side is sensitive and reliable.
3、 Container Type Substation Security and Protection
Grounding system: Ensure that the grounding system of the Container Type Substation is in good condition and the grounding resistance meets the specified requirements. Regularly check whether the grounding wire is firmly connected and whether there is any rust, breakage, or other phenomena.
Safety protection device: Check whether the safety protection device of the box type substation is intact and can function normally. Ensure that the safety warning signs inside the box are clear and prominent, reminding operators to pay attention to safety.
Firefighting equipment: Equipped with necessary firefighting equipment and regularly inspected. Ensure that operators are familiar with the use of fire-fighting equipment so that they can take prompt measures in emergency situations.
4、 Container Type Substation Operations and Records
Standardized operation: Operators should receive professional training and be familiar with the operating procedures and safety precautions of Container Type Substation. During the operation, it is necessary to strictly follow the operating procedures to avoid equipment damage or safety accidents caused by illegal operations.
Maintenance records: Establish a maintenance record file for the box type substation, recording information such as the time, content, and replaced components of each maintenance.
Analyze the operation status and maintenance requirements of the equipment through Container Type Substation maintenance records, providing reference for subsequent maintenance work.
