11kV - 800kVA Cast Resin Dry Type Transformer , Three Phases , Two Winding , Power Distribution
The standard transformers with IP-class protective enclosure is IP20. Subject to client need , we can also provide IP30 to IP40 . Enclosure material is made by common steel plates,stainless steel plants or aluminium alloy and can be acid-washed,parkerised and powder-painted.
The temperature controller can be installed on transformer body or on the wall of enclosure ,which are reliable and convenient for users to check.
Safe operation and working life of power transformers depends largely on the safety and reliability of transformer winding. If the temperature of transformer winding exceed the temperature which insulation withstand, it will damage the insulation. This is one of the most important reasons that transformers cannot operate normally.
LD-B10 series temperature controller of dry transformer (Referred to as temperature controller) is an intelligent controller designed especially for safe operation of dry transformer. The temperature controller features adoption of single chip computer technology and utilization of the platinum thermo-resistors embedded in the winding of the dry transformer for detection and of temperature rise of the transformer windings. It can start or stop the cooling fan automatically for forced air cooling of windings and control over-temperature alarm and over-temperature tripping output so that the transformer will be operated safely.
