How to check electrician certificate online in 2016 Houjie, Dongguan, electrician training institution

The soft starter integrates the functions of traditional motor protection circuits, such as motor overheating protection, phase failure protection, underload protection, overload protection, overvoltage protection, undervoltage protection, blocked rotor and stall protection, as well as the soft starter's own overheating protection, etc. . Overheating protection. After starting the motor, the soft starter will calculate the temperature rise of the motor based on the rated current and actual operating current. When the temperature of the motor exceeds the preset limit temperature, the soft starter immediately cuts off the circuit to implement overheating protection.

When the winding temperature increases, the resistance value of the resistor gradually increases to implement overheating protection for the motor. . Phase failure protection. When a certain phase of the motor power supply is low or has a phase failure, the three-phase current will be unbalanced. When the unbalanced current reaches the preset trip level of the soft starter and exceeds the trip setting delay, the motor will stop running. Phase failure protection. Underload protection. Underload protection is also undercurrent protection. When the motor is working at full voltage, the soft starter's underload protection function monitors in real time if the motor current suddenly drops beyond the underload trip setting range and exceeds the trip setting delay
