2 Striking potential generator technical order
2.1 Generator structure
2.1.1 Uses Swiss HAEFELY Corporation HG series the main return route design, thus has realized the whole subminiature.
2.1.2 uses each minute revolution of low speed gear rack drive reorganization at all levels of sphere gaps, not only does not have the noise, the attrition to be small, moreover locates is fast, is accurate.
2.1.3 Uses the accent wave resistance fixed organization which the spring compression connection, the convenience pull out insert, had guaranteed the contact reliability, causes the output wave shape smooth burr-free.
2.1.4 Coordinates NAIVGCS2000A control system's pulse amplifier to be possible to enable synchronized sphere gap to 20% above triggering scope, guarantee triggering reliability, completely automatic control convenience is reliable.
2.1.5 Synchronization sphere gap's triggering nonpolarity effect, does not need bilateral triggering.
2.2 Main capacitor
2.2.1 Main capacitor uses the high density solid capacitor, each Taiwan Telegraphic Transmission capacity is: 0.75±0.05 μF, the d C operation voltage is: ±200kV, the capacitor natural inductance is smaller than 0.2μH, the weight is light, the volume is small, is the domestic origination.
2.2.2 Capacitor the concave-convex distortion is smaller than 1mm under the normal work condition and the working conditions.
2.2.3 Capacitor for the solid insulation medium and the outer covering does not have problems and so on oil leak, distortion.
2.3 Adjusts the wave part
2.3.1 Wave, the wave rear resistance has the enough calorific capacity, may guarantee the generator long time continuous running.
2.3.2 charging resistor has the enough calorific capacity, may guarantee the generator long time continuous running.
2.3.3 Wave, the wave rear resistance uses the shape of strip structure, uses the Kang copper wire to circle the system without the feeling to become, exterior uses the insulation resin vacuum casting, attaches for the spring compression connection type, easy to install.
2.3.4 Wave, the wave rear resistance's company attaches uses the 3mm stainless steel wire cutting manufacture.
2.3.5 altogether has 3 group of wave resistance, 2 group of wave rear resistances to use in the lightning surge voltage full wave experiment and 3 group of wave resistance, 2 group of wave rear resistances uses in operating the striking potential full wave experiment, and some 1 group of charging resistor and protective resistor
2.4 The automatic control, protective system automatic operation.
