filament transformer

英 [ˈfɪləmənt trænsˈfɔːmə(r)]

美 [ˈfɪləmənt trænsˈfɔːrmər]

丝极变压器；灯丝变压器

If the filament transformer has a center tap, don't use it.
如果变压器灯丝绕组有抽头，请不要使用它。
Line frequency hum, primarily induced by imbalance in the filament circuit wiring, the transformer used to power the filament, coupling into the signal leads, etc.
市电频率Hum，主要原因包括灯丝线路走线导致的不平衡；供给灯丝的电源变压器（缺陷）导致电源杂波耦合进入信号通道，等等。
High-precision, high-stability and big-current filament transformer has been designed, it provides a stable current source for the tube filament.
根据电子管灯丝电流的要求，设计出了合理的高精度、高稳定性、大电流的灯丝变压器，为电子管灯丝提供稳定电流源。
According to the requirement for the stability and the adjustability of the filament current, the steady current plate that can control the measurement of the filament current has been designed by adjusting the voltage at the primary side of the filament transformer.
根据灯丝电流稳定度和可调性的要求，开发了可以调节灯丝电流的稳流板。通过对灯丝变压器的初级端的电压控制达到控制灯丝变压器次级即灯丝电流的大小。
