Product description
The company adopts foreign advanced technology to develop SC(B)18 series with packing thin insulation dry type transformer, It has the characteristics of maintenance-free, damp heat resistance, fire prevention, explosion protection, small local discharge, low noise and strong heat dissipation ability. It can improve the capacity operation under forced air cooling conditions. Filling the coil with glass fiber mesh board enhances the coil's ability to resist sudden short circuit. At the same time, the filling type resin and copper conductor thermal expansion coefficient is similar, its anti-cracking performance is good; Equipped with temperature controller, with fault alarm, overtemperature alarm, overtemperature trip and black box function, can be connected to the computer through RS485 serial port centralized monitoring and control. It is suitable for high-rise buildings, airports, stations, docks, subways, hospitals, power plants, densely populated areas and petrochemical plants, nuclear power plants, nuclear submarines and other places.
Product Features
1. Low loss: The no-load loss of the product is 20%+ lower than that of scb11 product, with good energy-saving effect, economic operation and free for maintenance.
2. Low noise: The noise of this product is 10-15 dB lower than the "6-220 kV transformer sound level" of the current professional standard JB / T 10088-1999.
3. Low partial discharge: Adopt advanced mixing and vacuum membrane degassing technology to evenly mix the resin and remove bubbles in the mixture. This kind of raw material has dense solidification structure and can resist natural gas, explosion and environmental pollution.All high and low Voltage coils are injected under vacuum pressure. The local discharge electrode of this product is low and can be controlled below 5pc.
4. Safety materials:Glass fiber and other insulating materials have automatic stop characteristics, and resin will not produce toxic and harmful gas at high temperature,and will not produce arc when in short circuite.
5. High mechanical strength: filling resin reduces the difference of injection expansion coefficient, small curing shrinkage, small internal stress and high hardness of solidified body. The epoxy resin coating on the inner and outer surfaces of high and low voltage coils has the same structure as steel reinforced concrete. Its mechanical strength is greater than that of pure epoxy resin, and it can withstand the action of sudden short-circuit electrodynamic force without damage.
