In the electric heating furnace should be how to choose a thyristor module

by:Positioning     2021-04-29
Thyristor modules used in electric heating furnace control cabinet, by temperature control instrument of temperature sensor to collect temperature in the furnace, and the constant temperature instrument to control the output voltage of intelligent thyristor voltage regulating module, forming a closed loop system, temperature to maintain a constant temperature in the furnace. Thyristor module is the key power device in the electric heating furnace control device, the machine device is reliable and correct selection of thyristor ( Silicon controlled rectifier) Regulating module parameters such as rated voltage, rated current has a lot to do. Thyristor module selection principle of work is to consider the reliability, current, voltage must have enough allowance. General furnace rated voltage is 380 v, choose the working voltage is 460 v thyristor module, other voltage thyristor module need to order. Choice of thyristor module current and wire heating furnace must be considered, Or heat) The rated working current and intelligent thyristor voltage regulation module maximum output voltage value, if the heating wire for the NTC or PTC properties ( The heating wire rated current changing with temperature, temperature is very low when the phone is switched on, rated current large or heating to the highest temperature, the rated current large or heating to the highest temperature, the rated current is big , must consider the working state of heating wire the maximum current value, as a heating wire to determine the rated current value of the specifications of the intelligent thyristor module size. Thyristor module, we use the most professional attitude, concern you the most subtle, want to think of the client, the urgent need of the client, in a very quality, fill and level up your fears.
