Outdoor An/Af Cooling Mode 11KV Distribution Transformers
Outdoor An/Af Cooling Mode 11KV Distribution Transformers PRODUCT FEATURES
Adopting advanced technology and international first class manufacturing equipment, SC-series resin casting dry type transformer chooses super quality raw materials, with scientific composition, strictly controlled process and higher inspection standards, so it owns the following advantages:
1. Good heat dissipating because of thin resin coated on outside of the coils, and normally adopting natural air cooling (AN). Any protection level transformer could be fitted with fan cooling system (AF) to improve short time overload ability and ensure safety running.
Outdoor An/Af Cooling Mode 11KV Distribution Transformers TEMPERATURE CONTROLLING SYSTEM
Temperature controlling system consists of temperature controller and PT100 temperature measuring component, which are installed in the hottest point of the coils for realizing the temperature measuring and controlling of transformer. It can switch on/off the cooling fan according to temperature change of coils. While the temperature rises up to a certain value, it will send out an alarm signal. PT100 temperature sensor is a measuring component of temperature controlling system. While temperature changes, the resistor of sensor will follow the changes, then the micro processing system of controller measures temperature of coils according to the change value of resistor. If sensor has wire-breaking trouble , temperature controller will send out fault signals of sensor. Temperature controlling system can directly indicate temperature of three-phase coils of transformer during running and it can realize the connection with computer, to realize collective control. Normally, temperature-controlling system is installed in transformer directly. And it can also be installed in duty office as requested.
Outdoor An/Af Cooling Mode 11KV Distribution Transformers STANDARDS
This product adopts standards of GB1094, GB1094.11-2007, GB/T10228-2008 and it satisfies
standards of DIN42523, IEC726. Routine test, type test and special test are all according to standards of GB1094.11-2007, GB/T 10228-2008,and Noise-level test, which is specially arranged as routine test item.
