Application
High voltage isolating switchgear
Features
High starting torque: Since the isolating switch may encounter increased friction due to environmental reasons (such as dirt, ice and snow) during operation, the motor needs to have sufficient starting torque to overcome these static friction forces.
Reliability: In high-voltage electrical equipment, any failure can have serious consequences. As a result, these motors are typically designed for high reliability and the ability to operate in harsh environments, including extreme temperatures, humidity, dust, and corrosive environments.
High insulation level: The high-voltage isolating switch operates in a high-voltage environment, so the insulation level of the motor must be high enough to avoid voltage flashover and breakdown.
Long life design: These motors should be designed to withstand thousands of operating cycles to ensure stable operation of the isolating switch for a long time.
Compact structure: Considering the space limitations of the isolating switch, the motor is usually designed to be compact for easy installation and maintenance.
Dual capacitor design: Single-phase capacitor motors may use starting capacitors and running capacitors, where the starting capacitor is used to increase starting torque, while the running capacitor is used to improve operating efficiency and smooth output.
High efficiency: Under the same power conditions, capacitor motors are designed to provide a higher energy efficiency ratio.
Stable operation: Due to the phase correction effect of the capacitor, the motor can maintain a relatively stable speed during operation.
Relatively economical price: Compared with complex three-phase motor systems, single-phase capacitor motors are relatively economical in price because of their simple control and high popularity.
