Thyristor switch constituted by the electronic components, as long as access to the system after the charging power loss inevitably caused, which is a disadvantage when compared with conventional mechanical switches. Therefore, the design of thyristor switch on the main circuit in addition to fully consider the reliability factor, but also should consider how to reduce losses, SCR T435-800T, improve the operation of the economy. (L) Loss steady off thyristor switch under: mainly by flowing through a static grading resistor, dynamic voltage resistance of current levels, SCR, approximation is calculated as follows: where: V is the switching valve rated voltage in V; from the point of view of heat way thyristor, SCR T435-600T, no matter how one-way flow through the thyristor current waveforms, one-way thyristor conduction Just how much the design angle is equal to the rated current rms current I rms, SCR BT137S-600E, it is the equivalent of one-way thyristor heat and allowed. At room temperature and the gate shorted condition can be maintained SCR continues to conduct current is called the minimum required to maintain the anode current I. If the way thyristor anode current is less than this value, the check will be conducting thyristor state to the blocking state. SCR BT134W-600E, SCR, is provided by Wal-electronic Dongguan City is fertile Electronic Technology Co., Dongguan City is Wo Electronic Technology Co., Ltd (www.dgmydz.com) (www.dgmydz.com) strong, credible, FET and other industries in Dongguan, Guangdong has accumulated a large number of loyal customers.
