Conditions of Use

  • Type of device: Indoor type
  • Normal environmental conditions: Altitude does not exceed 1000m
  • Ambient temperature:

Maximum temperature: +40℃

Minimum temperature: -25℃( When -25 , it requires on-load switch and temperature controller)

Relative Humidity: 100%

Maximum daily average temperature: +30℃

Maximum annual average temperature: +20℃

  • The installation site should be clean and free of electric dust, no corrosive gas, and have good ventilation conditions. If installed in a basement or other poorly ventilated location, ventilation should be mandatory. This cast coil transformer requires approximately 3~4m3/min of ventilation per 1KW (no-load loss + load loss).
  • When installing the cast resin current transformer, it should generally leave the wall and other obstacles 800mm. There should be a distance of 300mm between adjacent transformers. For distribution boxes and other installations where space is limited, the above distances can be adjusted appropriately.
  • Under normal circumstances, the cast resin dry type transformers can be placed directly in the use site, and the installation can be put into operation after the inspection is completed. For earthquake-proof and other special requirements, the base where the transformer is installed should be embedded with bolts and the transformers Fixed by bolts and nuts.

Product Series Description

1. Temperature Display, Temperature Control System

According to the user's requirements, the dry type transformers can be equipped with a temperature display and temperature control system. It acts as an overload warning signal and automatically displays the temperature. When the internal temperature of the coil exceeds the limit set by the signal thermometer, the fan can be started and stopped, the power supply is tripped, and the transformer is cut off.

2. Cooling System

The cooling method is self-cooling (AN). When self-cooling, the output capacity is 100%, and forced air circulation cooling (AF) can be overloaded for 25% for a long time and 50% for short-term overload.

3. Protection Level

The general protection level of the cast resin transformers is IP00, that is, the cast coil transformer is not equipped with the outer casing and is used indoors. If it is needed outdoors, it can be equipped with the outer casing and IP20 or IP23 (when the transformer protection level is high, the transformer derating operation should be considered). Note: The IP20 housing prevents solid foreign objects greater than 12mm from entering, providing a safety barrier to live parts. Based on the IP20, the IP23's protective case prevents water droplets from flowing within 60 degrees of the vertical line.
