1无功功率补偿的种类和特点1.1集中补偿在高低压配电所内设置若干组电容器,电容器接在配电母线上,补偿供电范围内的无功功率1-2组合就地补偿(分散就地补偿)电容器接在高压配电装置或动力箱的母线上,对附近的电动机进行无功补偿,1.3单独就地补偿将电容器装于箱内,放置在电动机附近,对其单独补偿。电容器直接接在电动机端子上或保护设备末端,一般不需要电容器用的操作保护设备,称为直接单独就地补偿。
1 types and features of reactive power compensation 1.1 centralized compensation in the high and low voltage distribution within the set of several capacitors, capacitors connected to the distribution bus, the compensation of reactive power within the range of 1-2 combinations of local compensation (decentralized Compensation) The capacitor is connected to the busbar of the high-voltage power distribution unit or power box, and the nearby motor is reactive-compensated. 1.3 Compensation alone Place the capacitor in the box and place it near the motor to compensate for it. Capacitors directly connected to the motor terminal or the end of the protection equipment, generally do not need the capacitor with the operation of protection equipment, known as the direct separate on-site compensation.
