摘要： PURPOSE:To improve surge voltage protective capacity by boosting the voltage at a starting electrode arranged closely to a main discharge gap provided across a load to be protected through a booster which is excited by a current flowing through a non-linear resistor connected in parallel with the load. CONSTITUTION:Main electrodes 2, 3 are fixed to lead wires l0, l1 connected to the opposite ends of a load 7 to be protected and the gap between the main electrodes 2, 3 is set to a predetermined value thus forming a discharge gap 1. A single winding booster 5 is connected between 1 starting electrode 4 arranged closely to the main electrodes 2, 3 and the lead wire l0. A non-linear resistor 6 allowing only small current for a voltage lower than a predetermined level and allowing abruptly increased current for a voltage exceeding over the predetermined level is connected between the intermediate terminal of the booster 5 and the lead wire l1. When a surge voltage enters between the lead wires l0 and l1, large current flows through the non-linear resistor 6 to produce a high voltage on the starting electrode 4 thus inducing discharge between the main electrodes 2, 3. Consequently, high surge voltage is discharged through the gap 1 and the load 7 is protected from high voltage.

摘要： PURPOSE:To provide an electric power system using a stable vacuum trigger gap device having a low trigger energy to enable AC operation, by furnishing a trigger part for supplying trigger current to both of the main gap, and allowing this trigger current to flow over a certain value. CONSTITUTION:A vacuum trigger gap device 1 furnished with main electrodes 2a, 2b and trigger electrodes 3a, 3b within a vacuum vessel is connected with a load 9 and an AC power supply 10, and trigger current is supplied through a pulse transformer 12 from a trigger power supply 11, which is controlled by a control part 13. To this control part 13 the main current value is entered by a main current sensing part 14, and external command is given to this control part 13 through an external command terminal 15, Therein the control part is controlling the trigger power supply until the main current IM meets the condition expressed by Eq. I, where Ic is current value when the main current generates stable discharging. Thus stable discharging is obtained to establish On condition between electrodes.

摘要： PURPOSE:To perform switching of high voltage at a high speed by shortcircuiting two electrodes through discharging, decreasing rapidly the ions generated by discharging through utilization of the pressure relieving phenomenon of insulating gas, and again insulating the two electrodes electrically from each other. CONSTITUTION:At a distance d a pin electrode 1 and a mating electrode 2 are faced to each other in a sealed space 4 filled with an insulating gas at a pressure over 1kg/cm . A highly repetitive trigger pulse voltage with a short time of rising is impressed to a trigger electrode 3, and thereby insulation destruction is generated between the tip of trigger electrode 3 and the electrode end 10 of pin electrode 1 so as to provide partial discharging. The main discharge is induced between the electrode end 10 of the pin electrode 1 and the electrode end 10 of mating electrode 2 by means of the generated ions supplying effect and electrons irradiating effect to cause shortcircuiting of the two electrodes-i.e., switching is made. The ions generating by this discharge are decreased rapidly by the pressure relieving phenomenon to provide restitution to the initial state. Thus high speed switching is made practicable.
