Do not have a very professional, can mark the specific layout, specifications can be
Transfer test Note: in the high-pressure test equipment and high voltage around the lead, should be installed to block and hang warning signs When conducting a high voltage test, the operator and the high voltage circuit should have sufficient safety distance after the end of the high-pressure test, the DC test equipment and large capacitance of the equipment to be tested multiple discharge, discharge time of at least 1min or more Where the absorption ratio of less than 12 of the motor, should first dry and then exchange pressure test circuit breaker AC voltage test should be in the sub-closing state were carried out separately In addition to the complete installation of the factory, the insulation equipment should be separated from each other to do DC voltage, the test voltage 05 times the rated voltage per stage increased in stages, each phase to stay 1min, and record the leakage current
In the PCB design interface, select the power and ground network in the browser. Then edit the properties. Or set before wiring.
Phase correction, the first is to prevent parallel lines in the line when the phase short circuit, the second is in the line automatic device action, because the action time is short or the line is longer capacitive, due to different phase, resulting in the lower three-phase electricity Equipment impact
