Protective untriggered gaps represent 2- and 3-electrode gas-discharge devices, capable of dramatic change of their conductivity and admittance of large current while being influenced by applied voltage. In comparison with other devices of analogous use (impulsive tyrotrons, thyristors and trigatrons) they have a number of advantages:
- the lack of heat;
- immediate preparedness for work;
- high efficiency with great levels of power handling;
- high working voltage and the current of commutation in the presence of minimal overall dimensions and mass;
- stability towards considerable current overload.
The field of application of protective untriggered gaps:
- in the communication equipment for the protection of air-lines, cable lines, wire-lines and the elements of the communication equipment from external over voltage;
- in instrumentation for the change of pulse shape;
- in automated mechanisms and telemechanics for circuit switching;
- in transport for the ignition of gas turbine engines of internal combustion;
- in medicine for the commutation of high-voltage impulses fed on X-ray tubes;
- in nuclear and experimental physics.
