High voltage shunt capacitor is mainly composed of core and shell.The core consists of dozens of series parallel elements in a particular way,separated and wrapped by insulating element.The shell is welded with a thin steel plate,and the wall is provided with an arch lift,and a mounting bracket is welded,and the casing is welded on the box cover..The component is rolled by PP film and aluminum foil.In addition,the capacitor is filled with good electrical performance of the insulation liquid.
The high voltage shunt capacitor is made of thick PP film and immersed in high vacuum state for the composite medium and high purity aluminum foll as the electrode plate,mainly used in the AC power system of the nominal voltage 1000V above,frequency 15-60Hz to compensate reactive power,improve power factor reduce line loss,save energy,improve power quality.
The product performance is in line with the 11024-2001 GB/T “nominal voltage 1Kv AC power system with parallel capacitor” series standard requirements (equal to IEC 60871-1997)
-The altitude dose not exceed 1000m, and the ambient air temperature is between -40℃ and +40℃
-No mechanical vibration,no harmful gas and steam,no electrical conductivity and explosive dust in the installation place
-continuously running voltage 1.0Un,the maximum long time over voltage is no more than 1.1Un
-steady over current(including harmonic current)not exceeding 1.35In.
-when the capacitor operated,the residual voltage of its terminal should no exceed the rated voltage of 10%
