BP4G frequency-sensitive rheostat start-up performance analysis.
The starting performance of BP4G frequency-sensitive rheostat is one of its key characteristics, which is of great significance for the normal operation and protection of the motor. The following is a specific analysis of the starting performance of BP4G frequency-sensitive rheostats:
1.Load factor.
The load factor of BP4G frequency-sensitive rheostat is 07-1.0 range. This means that when the motor is started, the BP4G frequency-sensitive rheostat can automatically adjust the output according to the load situation, ensuring that the motor starts smoothly and avoiding motor damage caused by overload.
2.Multiple of starting torque.
The starting torque multiple of BP4G frequency-sensitive rheostat is 12。This means that when the motor is started, the BP4G frequency-sensitive varistor can provide enough torque to quickly reach the rated speed of the motor. At the same time, this torque multiplier also ensures that the starting process of the motor does not cause excessive impact on the equipment.
3.The ratio of the starting current to the cutting current.
The ratio of the starting current to the cutting current of the BP4G frequency-sensitive rheostat is less than 25 times the rated current. This means that during the motor start-up process, the BP4G frequency-sensitive rheostat can effectively limit the peak current and avoid damage to the motor or rheostat caused by excessive current. At the same time, this ratio ensures that the starting process of the motor does not place an undue burden on the power grid.
4.Continuous starting performance.
The BP4G frequency-sensitive rheostat allows three consecutive starts, but the total starting time must not exceed 90 seconds. This performance enables BP4G frequency-sensitive rheostats to provide reliable starting support and ensure the normal operation of equipment in equipment that requires continuous starting. At the same time, the limitation of the total starting time also avoids overheating and wear and tear of the equipment due to continuous starting.
