1. Insulation resistance measurement of cable main insulation 1.1 test purpose Initially judge whether the main insulation is damp and aging, and check whether there are defects in the cable main insulation after the withstand voltage test. The decrease of insulation resistance indicates that the insulation is affected with damp or aged or deteriorated, which…
At present, electric vehicle motor controllers mostly use three-phase full-bridge voltage -type inverter circuit topology, and some products are pre-mounted with bidirectional DC/DC converters to increase the input AC voltage at the motor end , increase the output power at high speeds , and reduce motor design and production costs. The DC support capacitors in…
The vibration sensor is a widely used alarm detection sensor. It senses the parameters of mechanical motion vibration (such as vibration speed, frequency, acceleration, etc.) through the internal piezoelectric ceramic sheet and spring weight structure and converts it into an available output signal. Then it is amplified by an operational amplifier such as LM358 and outputs a…
