摘要:
A multiple rapper control (10) for an electrostatic precipitator for monitoring and individually controlling each of a plurality of rappers based on computer (12) stored rapper characteristics including the voltage type, the voltage level, the pre-set electrical input current, the minimum increment between energization cycles, and the maximum duration of energization. Each rapper is connected to a TRIAC switch device (20) linked to a computer (14) and a power control means (16) to vary the input power to each rapper supplied from a power source (18). Current detecting means (22) is bi-directionally connected to the computer (14) and is connected to the power control means (16) to sense and measure the peak electrical input current to each rapper. A preselected logic sequence stored in the computer (12) controls power to each rapper. Optional polarity reversal means (37) eliminate undesirable magnetization of rapper components.
