An intelligent vacuum contactor synchronization debugging instrument and testing method

Abstract

The present invention provides an intelligent vacuum contactor synchronization debugging instrument and testing method, wherein a PLC calculation unit is connected to a vacuum contactor through a power unit and a variable speed propulsion unit; the PLC calculation unit is also connected to the vacuum contactor to obtain the on-off state of the vacuum contactor, and obtain the on-time point when the vacuum contactor is on and the off-time point when the vacuum contactor is off; the PLC calculation unit sends a control action instruction to the power unit, so that the power unit drives the vacuum contactor to perform on-off action through the variable speed propulsion unit, and the PLC calculation unit records the time point of sending the control action instruction; the PLC calculation unit tests the action synchronization of the vacuum contactor in combination with the on-off time point of the vacuum contactor and the time point of sending the control action instruction; the debugging instrument uses the PLC timing calculation function to obtain scientific and accurate data. With the use of power propulsion, the test results are more accurate.
