Product Description:

Cast resin dry-type transformers

1.       Features

SC(B) Series Cast Resin Dry type Transformers (CRDT) are produced by using full auto vacuumcast transformer software technology of thin insulating tape filling from Germany HTT MASCHINEN GMBH, full-auto vacuum cast equipment from GermanyHeydrich GMBH, High-Low voltage foil winding machine from France BR company,full-auto silicon steel sheet cut-to-length line from Germany GEORG GMBH, highquality epoxy cast resin materials and high-permeability grain-oriented cold rolled silicon steel sheets. Based on advanced technology, raw materials with high quality, scientific management and complete inspection manners, the features of the product are as follows:

  • Coils are covered by glass fiber and moulded by epoxy cast resin material under vacuum,which has the advantages of perfect mechanical performance, no cracking, nobubbles inside, little partial discharge, high reliability and long servicelife.

  • Better humidity resistance. CRDT can be operated in severe environment and high humidity by reasons that HV&LV coils adopt high-temperature moulding structure with low hygroscopic and clamps for core are anti-corrosion.

  • Flame retardance, explosion proof and friendly environment. Insulation materials (such as glass fiber) used for coil are not very flammable and can be self-extinguishing,electric arc resulted from short-circuit cannot start a fire. There are nohazardous fire gases from resin under high temperature.

  • Thin insulation structure and air flues inside can strengthen heat emission and short-circuitoverload capacity.

  • Low loss and low noise. Core lamination adopts 45° full sloping seam and four orseven level step-by-step system, which improves efficiently the magnetic fluxdistribution at the corner of iron core and reduces no-load loss and noiselevel.

  • Excellent ability to withstand short circuit and lightning impulse.

  • Smallsize, light weight, simple installation and free maintenance.

7.      Temperature control system

The safe operation and service life largely depends on security and reliability of winding’s insulation.   When winding temperature is beyond insulation tolerable temperature, the insulation is damaged,  which is the main reason that may lead to the transformernot be normally used. BWD3K series temperature control system measures thetemperature of LV winding by PTC temperature measurer and can control coolingfan according to the measured temperature values.

Features:

  • Integrating of temperature display and control.

  • The advanced circuit design can effectively restrain circuit drift, andhas strong anti-interference ability

  • Has Watch Dog function and power failure detection circuit on powersupply to make sure that the thermostat can work well in harsh environment.

  • According to user requirements to provide the three-phasetemperature value 4-20mA analog output function and RS232 or RS485 computer interface, to meet the requirements of automatic monitoring.

  • Simple and practical draw type installation, easy to remove.

Main functions:

1.Three-phase winding temperature data-loggingand maximum value display.

2.Automatic open and close fanfunction/manual start-stop function according to set temperature

3.Over-temperature alarm, over temperaturetrip function.

4. Fault detection alarm, mute function.

5. Fan start-stop function on a regularbasis.

* 6. Output and temperature synchronous 4 ~20A standard value electric current.

* 7. RS232 or RS485 computer interface output,communication distance reaches 1200 meters.

Note: "*" is optional.

Product with enclosure: Thecontroller is installed at the LV side.

Product without enclosure: Thecontroller is installed on the clamp supporting plate at the LV side.
