The electric capacitor is the common name of the induction heating device with the power capacitor, sometimes called the resonant capacitor, the compensating capacitor or the commutation capacitor. Electric capacitor is mainly used for not more than 3.6 kV rated voltage, frequency 50 KHZ and under controlled or adjustable ac power system, is dedicated to the improvement of induction heating, melting, stirring or casting device, and the power factor of similar applications. The product performance conforms to GB/T3984-2004, the standard requirement for electric capacitor for induction heating device.(GB/T3984 – 2004 same as IEC 60110 - 1998).
2.1 The altitude is no more than 1000m,indoor use.
2.2 There must be no heavy mechanical vibration, no harmful gas and steam, no conductivity and explosive dust when installation.
2.3 The inlet temperature of cooling water does not exceed 30 ℃. And for capacitor under 1000 kvar is not less than 4 l/min, 1000kVar and above are no less than 6L/min.
2.4 Air-cooled electric capacitor,the minimum clearance between the capacitor should not be less than 50mm, and the wind speed is not less than 4m/s.
2.5 The capacitor ambient air temperature is less than 50 ℃.
2.6 Long-term overvoltage (no more than 4 hours In 24 hours) is no more than 1.1Un, and the current (including harmonic current) is no more than 1.35 In.
The electric capacitor is mainly composed of the heart, shell and insulating porcelain etc., and the heart is composed of array elements in parallel. Water-cooled capacitor,the side of the heart (double-sided water cooled) is welded with a cooling water pipe,and the shell is made of aluminum alloy plate,the two sides of the wall have the bracket for welding and installing,and the lid of the box is equipped with the outlet pipe (air-cooled capacitor without cooling water pipe) or porcelain casing copper terminal. The inside of the box is filled with the excellent insulating liquid medium(not including PCB).
