The utility model provides a zero strikes reactive power compensator, includes the condenser that three -phase switch, air switch, contactor, 3 star connection or angular form are connected, its characterized in that: zero strikes reactive power compensator is still including transferring the merit ware, being used for 5 volt constant voltage power supply for transferring the power supply of merit ware, the pile head star meets three discharge resistance on star connection's the three condenser. Compared with the prior art, the beneficial effects of the utility model are that, owing to removed the reactor, increased accent merit ware, discharge resistance, consequently not only guaranteed reactive power's compensation, more improved the quality of supply of power in addition, protected condenser itself and other online safety with electrical apparatus.
