Bir toroidal transformatör seçerken, toroidalin gücü transformatör yükün gerilim ve akım kullanımına göre belirlenmelidir. Bir toroidalin nominal çıkış akımı transformatör is the output current at full load. When overloaded, the toroidal transformatör can output more than 30% of the rated current. The overload capacity of toroidal transformatörs is very good, but the following two points need to be noted.
1. Aşırı yüklenmiş makine ve ekipmanı başlatmak için kullanılır
The current of some devices is rated during operation, but the current at startup is very large, sometimes exceeding 30%~50% of the rated current. For example, the overload capacity of an AC servo motor is usually designed to be 3 times the rated operating current. When the load starts, the current is large, which requires the toroidal transformatör to be overloaded for a short time. Such a device with overloaded driving current is equipped with a toroidal transformatör, and the rated output current of the transformatör needs to be considered to exceed about 20% of the rated current of the device. Due to frequent start-up overloads, the temperature of the toroidal transformatör rises, and the long-term transformatör life becomes shorter.
2. Aşırı yüklenmeyen ekipman için uygundur
Many devices are designed with the maximum operating current in mind and the startup current does not need to be overloaded. For example, stepper motors are used as equipment power, and the operating current is the same as the starting current. When selecting a toroidal transformatör, it is not necessary to design a margin for the output current of the toroidal transformatör as long as the output current is equal to or greater than 10% of the maximum current of the stepper motor driver. Stepper motors never have overload current. In more work environments, the power of stepper motors is variable. This requires that voltage and current parameters should be determined during structural design, and reasonable power should be given artificially. In fact, the power of aBir toroidal transformatör seçerken, toroidalin gücü transformatör should be determined based on the voltage and current usage of the load.
