Voltage regulator is divided into: autotransformer, isolation voltage regulator, oil immersed type induction voltage regulator, column type electric pressure regulator thyristor voltage regulator five. Method and voltage regulation device manual voltage and electric voltage. Pressure regulator noun explanation: pressure regulator English name The thyristor voltage regulator is also called "thyristor power regulator" "thyristor power regulator" or "power regulator" . "Thyristor" also known as "silicon controlled" (SCR) is a kind of four layer three terminal semiconductor device, it is connected to intermediate load in power supply and distribution, phase Trigger control circuit board should be, you can adjust the voltage applied to the load, the current and power. "Thyristor regulator" is mainly used for various electric heating device (such as an electric industrial furnace, electric heating drying machine, electrothermal oil stove, all kinds of reaction tank, a reaction kettle electric heating device) heating power adjustment, can be "manual" adjustment, but also can and electric control, intelligent instrument Regulating instrument, PLC and computer control system coordination, to achieve constant value or a procedure to control the heating temperature.
