FIG. 1 Schematic diagram of impulse voltage generator body
The impulse voltage generator is charged in an asymmetric voltage doubling mode, and the highest charging voltage of each stage is 200 kV.The main structure is insulated pillar tower type, each stage has a double bushing (or two single bushing) metal shell pulse capacitor, a pair of ignition ball gap, a wave head (or damping) resistance, a wave tail resistance, a charging resistance.
Each stage of the body has five insulating pillars, of which four coarse insulating pillars are used to support the pulse capacitor.carry wave head (or damping) resistance, wave tail resistance, charging resistance. A barrel shaped insulated pillar mainly supports a 200mm ignition ball gap.Three electrode structure and horizontal linear arrangement were adopted for each pair of spherical gaps.The ball gap distance is adjusted in a straight line driven by a motor, and the corresponding ball gap distance is indicated on the console by a pointer voltmeter.All resistors are inserted to facilitate disassembly and replacement.
The body is mounted on a movable channel steel chassis, which can be dragged by a traction rod at will. When lightning impulse voltage waves (including full wave and truncated wave) are generated, the resistance of wave head and wave tail are dispersed to all levels, forming a high-efficiency small discharge circuit.Several sets of wave-head resistors and one set of wave-tail resistors can meet the requirements of load capacitance range.
When operating impulse voltage waves are generated, lightning wave head resistances of all levels are retained as damping resistances of all levels. The operating wave tail resistances are dispersed in all levels, and the clamping tail resistances of all levels and charging resistances constitute actual equivalent wave tail resistances of the operating wave. The external wave head resistance is connected between the body and the wave head capacitance.Several sets of wave-head resistors and one set of wave-tail resistors can meet the requirements of load capacitance range.
When an oscillating lightning or oscillating operation impulse voltage wave is generated, its damping resistance and wave-tail resistance are dispersed among the levels, while the oscillating inductance is connected between the body and the wave-head capacitance.A set of oscillating inductance, damping resistance, wave tail resistance can meet the requirements of load capacitance range.When a steep wave is generated, the damping resistance (or short-circuit rod) and wave-tail resistance are dispersed to all levels to form a steep wave circuit. When the steepness of the steep wave fails to meet the requirements, a steepening device can be used.A set of damping resistance (or short circuit bar), wave tail resistance can meet the requirements of steep wave test.
