I: The structural feature
1: The equipment can be installed both indoors and outdoors. It uses the frame structure and can perform fixed switching on and switching off operations.
2: The equipment can be installed directly in the substation to perform the the switching on and switching off operations for the reactive power compensation capacitor cabinet.
3: The composition of a complete indoor frame type reactive power compensation capacitor cabinet: It is composed of the series electric reactors, the incoming wire holder and the capacitor rack; the empty cored electric reactor is generally mounted by stacking the three phases or arranging the three phases flatwise. The incoming wire holder includes the high voltage isolating switch, the discharge coil and the thunder arrester. The capacitor racks are generally arranged with two banks per row, total two rows; and for those capacitor racks with a large capacity, they can be arranged with two banks per low, total two rows. The incoming wire frame shall be installed in parallel with the capacitor frame, and their heights and depths shall be the same.
