Before putting a voltage transformer into operation, it must undergo thorough testing and be confirmed as qualified according to the handover test procedures outlined in relevant regulations. The following inspection items should be carefully checked:
(1) The appearance of the oil-filled transformer should be clean and free from damage. The oil level should be within the normal range, and there should be no signs of leakage. This ensures proper insulation and cooling performance.
(2) Porcelain bushings or other insulating materials must be inspected for cracks, chips, or any visible damage. These components are critical for maintaining electrical isolation and preventing short circuits.
(3) The primary and secondary side connections must be securely fastened, with good contact to ensure reliable current flow and prevent overheating or arcing. Loose connections can lead to operational failures or safety hazards.
(4) The outer casing of the transformer and the secondary circuit should be grounded at a single point. Proper grounding is essential for protecting both the equipment and personnel from electrical faults and ensuring safe operation.
In addition, it is recommended to check the manufacturer’s specifications and perform insulation resistance tests, polarity checks, and ratio verification to confirm the transformer’s performance meets all required standards before commissioning. This comprehensive approach helps prevent potential issues and ensures the transformer operates safely and efficiently throughout its service life.
Aquarium lights, also known as water plants growing lights, are mainly made of LED lamp beads, also known as LED aquarium lights, LED water plants growing lights, and LED water plants supplement light.
Aquarium lamp is a special kind of lamp, according to the growth law of plants, it must need sunlight, and the aquarium lamp is a lamp that uses the principle of sunlight to replace sunlight to provide the environment for the growth and development of aquatic plants.
