| Thyratrons
with "Cold" Cathode - Pseudospark Switches |
|
| |
|
|
| Description |
|
|
 |
|
| |
|
|
One of the most innovative products designed
and produced by PulseTech is a line of thyratrons
with non-heated cathode or pseudospark switches
TPI- and TDI-series.
The tubes are intended for use as closing switches in pulsed power
offering cost-effective solutions in environmentally safe,
energy-saving technology.
Presently Pulsed Technologies Ltd offer a range of
the thyratrons for:
- medium and high power
- high voltages from 1 kV up to 150 kV
- peak currents from 500 A up to 200 kA
The design of the thyratrons is protected
by RF patents (Nos 1792207, 1807798 и 2089003), the Inventor's
certificate №20201 and International Patent CT/RU 2005/000298. Priority
is effective since 02.06.2005.

| Basic Advantages |
|
|
|
|
The need for the pseudospark
switches was caused by the fact that new power technologies
require a reliable, simple and cost-saving switch.
Now the absence of hot cathode:
- leads to considerably higher
service life of the switch - 10 000 times more than for spark
gaps and tens times more than for conventional pulse thyratrons
- simplifies circuitry
- allows the switch to have the
highest surge capability
- gives the most low weight,
compact and affordable switch for the achieved electrical
parameters.

| Main series |
|
|
|
|
|
>>>TPI-series
-
hollow cathode thyratrons
operating in superdense glow and arc discharge. Intended for switching
of charge up to 10E-4 ... 10E-1 C per pulse. These thyratrons can be
used in applications such as pulse power supplies for lasers,
electrophysics and testing equipment with frequency up to 50 kHz, pulse
width 5...50000 ns.
|
|
|
|
>>>TDI-series
- power and very high power thyratrons (copper-arc
thyratrons) capable of switching up to some 10 C per
pulse. The thyratrons can be used as environmentally safe
substitute of mercury ignitrons.
TDI-thyratrons
are available in SN-configuration,
when the switch does not require for permanent heating of hydrogen
reservoir. |
 |
|
|
>>>TPU-series
hollow cathode tacitrons (opening switches)
with increased frequency range - up to 300 kHz.
Now under construction. |
