Aerospace: Used for insulation performance testing of high-voltage equipment such as aircraft and spacecraft.
Frequently Asked Questions
Q: Can dry-type transformers be installed outdoors?
A: Sure, but the prerequisite is that it must use a sealed or cast resin shell and meet the outdoor use grade (usually IP23 or higher). This type of design can prevent moisture, dust, and corrosive air, making it suitable for coastal, industrial, or humid areas.
Q: How to clean the surface ash of dry-type transformers safely?
A: When the power is off, use dry compressed air to blow and clean. Do not use a damp cloth to directly wipe the winding parts to avoid moisture infiltration and affecting the insulation performance of the equipment.
Q: Do dry-type transformers need to be equipped with temperature controllers?
A: In conventional scenarios, it is recommended to install a dedicated temperature controller that can monitor the operating temperature of the winding in real time. When the temperature exceeds the limit, it will automatically trigger an alarm or start the cooling fan, greatly reducing the probability of overheating faults.
Q: What is the safe distance from personnel during the operation of dry-type transformers?
A: For dry-type transformers with a voltage level of 10kV, the safety protection distance during normal operation should not be less than 0.7m. It is recommended to set up dedicated protective isolation barriers around to prevent non professionals from approaching.
