| The control device is indended to turn
on the triggered vacuum switch RVU-43.
The common view of the device is shown on the Fig
( 2 ). The device consists of the carriage with the electronic
equipment are fixed on it (1), the cover (2), the high voltage
transformer (3), the high voltage insulator (4), transformer
high voltage outputs (5), the power cord with it's plug (6),
the input signal plug (7), the earth terminal (8), the indicating
lamps (9,10), the fuse (11). The power supply - from mains
220 V, 50 (60) Hz.
The control device turns on when the power cord is plugged
to the mains (without the cpecial toggle switch). After ignition
the red lamp "Power" the control device is ready
to work. The voltage from the output of high voltage transformer
must be applied to the cathode and control electrode of RVU-43.
It is recommended the positive terminal to connect with the
control electrode and the negative - with the cathode. The
control device must be situated near the RVU-43 so as to the
length of connecting wire was no more 1.5 m. If the length
of connecting wire more than 1.5 m. the turn on current is
decreased and turn on time is increased.
For the actuation of the control device it is necessary positive
control voltage pulse 5-10 V, I=0,1-0,2 A and duration no
less 10 ms. The circuit of input signal is insulated from
power circuit for the excepting of the interference. The transformer
secondary winding also insulated from primary winding for
constant voltage 30 kV.
The circuit of the control device is shown on the Fig. (
