3.Product characteristics

4.1 The device can working long time under 1.1times the rated voltage of the steady-state voltage

4.2 The device can continuous working with less than 1.3times capacitor bank rated current.

4.3 The device adopt no thump high voltage breaker with zinc oxide lighting arrestor to limit the operating voltage made by switching capacitor bank

4.4 The device chose dry hollow reactor installed side of the power source or dry iron core reactor connected side of neutral point, in order to restrict switching in flashy flow and restrain ultrahamonics, improve network voltage wave form, the rated reactance rate 0.5-1% of the reactor is used for restricting switching in flashy flow, and the rated reactance rate 5-6% is used for restraining more than 5 times harmonic and restricting switching in flashy flow. the rated reactance 12-13% is used for restraining more than 3times harmonic and restricting switching in flashy flow.

4.5 The device adopt FD type discharge coil, can reduce the remaining voltage of the capacitor bank less than 75V from the rated voltage peak value

4.6 According to the requirements from system and customers, the device can chose local control or main control room centralized controlled or automatic control.

4.7 The device adopt single capacitor fusing protect is main protection, open triangle voltage, voltage differential motion ,unbalanced current protection as reserved protection, further more, the device equipped with over current ,over voltage ,and novoltage protection. These protection can chose better performance microcomputer capacitor protection monitoring equipment to meet the requirement of relay protection for the capacitor.
