Thyristor Switches

Thyristor switch mainly contains components as follows: Trigger circuit,
thyristor, diode and ancillary circuit. Trigger circuit will judge whether it
will output the control signal (DC12V) or not when voltage before and after
zero crossing switching, so as to turn on or off. The trigger circuit can
reliably ensure the output of the control signal. Radiator is mainly used for
conducting heat and cooling through installed a switch which contains over-
temperature protection and cooling fan controller, so as to provide the
operation with a safe and good condition. Compared to other thyristor switch,
this one has these advantages: no rush current, no touching noises; which is
more suitable for those switching frequently occasions, such as lifts, cranes
and welding machines.
Application
Tongdian Thyristor switch is in three-phase systems used to switch capacitors,
and other switching device compared to the, the switch has no inrush current
during switching, without exposure to noise and high switching frequency. These
advantages are achieved by triggering circuits, thyristor, diode, and some
auxiliary circuits. The switch is suitable for the occasion which changes the
load quickly.
