Embodiment 1

[0021] Gap-adjustable main control switch for pulse power system (applicable to occasions with working voltage between 10 and 50 kV and high requirements for overcurrent capability). See figure 1 , the switch includes switch case 1, switch case side block 2, anode support 3, anode 4, cathode 5, trigger electrode sheath 6, trigger electrode 7, anode terminal 8, trigger electrode terminal 9 and knurled grub screw 10.

[0022] The switch housing 1 is made of cylindrical plexiglass material, which is convenient for observing the internal conditions of the switch. The thickness of the cylinder should be >10cm to ensure sufficient strength, and the length of the cylinder should be greater than the length of the anode 4 and cathode 5 inside the cylinder + 50kV / 30kV·cm-1 (the length of the air gap to be guaranteed under the highest working voltage); the switch housing side shield 2 is also made of plexiglass, and its diameter is 1.5 times the outer diameter of the switch housing 1; ...

Embodiment 2

[0030] Self-breakdown spark gap switch for pulse power system (applicable to occasions with working voltage between 10 and 50 kV and high requirements for overcurrent capability). In this embodiment, the trigger electrode 7 and its accessories are not required, and the cathode 5 has a solid structure in the center because the trigger electrode does not need to be placed. The other parts are connected in the same manner as in Example 1.

[0031] In this embodiment, after the above components are connected according to the method described in Embodiment 1, the positive pole of the circuit is connected to the anode 4 of the switch, the ground of the circuit is connected to the cathode 5 of the switch, and the air gap between the anode 4 and the cathode 5 is adjusted. Make it slightly larger than the air insulation distance of the working voltage (considering that the breakdown voltage of gas is slightly lower than 30kV / cm under normal conditions). When the circuit is working, th...

Abstract

The invention discloses a spherical electrode spark gap switch with an adjustable gap. A switch housing is cylindrical; a switch housing side baffle is combined with the switch housing through a bonding method; an anode support is fixed together with the switch housing side baffle through a screw and combined with a stud of an anode through a thread on a central through hole of the anode support; a conductor is fixed on an anode terminal through two nuts; one end of the anode in a switch cylinder body is a discharging spherical part; the other end of the anode is the stud; and the stud also has an effect of wiring the anode while having an effect of supporting the anode. A cathode and a cathode support are integrated; a trigger electrode is placed or not placed at the central part of the cathode; if the trigger electrode is placed at the central part of the cathode, the trigger electrode is placed in the cathode after being protected by a trigger electrode sheath; and a lead of the trigger electrode is led in through a trigger electrode terminal and a knurled thumb flat-head screw. According to the invention, the length of a discharging gas gap is adjustable, the length of the discharging gas gap can be flexibly changed according to requirements on switch discharging voltage, and the working range of the switch is wider.

Description

technical field [0001] The invention relates to a spherical electrode spark gap switch with adjustable gap, which is used in the fields of pulse power supply, air breakdown characteristic research and the like. Background technique [0002] Pulse power technology is a technology that compresses energy in time and space, and then releases energy to specific loads with higher power in a shorter period of time. The pulse power supply is the key device in the pulse power system. Its function is to generate high-voltage and high-instantaneous-power pulses in a short period of time to drive specific loads. It generally consists of three parts: energy storage devices, high-voltage switches and loads. , where the high-voltage switch is the core component of the high-voltage pulse power supply, and the performance of the high-voltage switch directly determines the overall performance of the power supply. [0003] At present, due to the wide application of pulsed power supplies in in...
