Abstract
The utility model relates to a high-voltage power supply component used on an instrument. A single-arm type or a push-pull type self-excited oscillation circuit composed of a base-pole return circuit connected with a silicon transistor of a germanium diode in series, and a doubling circuit stacked up by building block type rectifying circuit units connected in series are adopted. Consequently, a whole high-voltage device including a necessary filtering testing circuit is conveniently assembled in a metal outer shell playing a shielding action.
Description
The utility model belongs to field of electronic devices.
At present, the 500-3000 of extensive use volt high voltage source is made up of self-excited oscillation circuit, voltage-multiplying circuit and the filter circuit of frequency from several thousand to tens KHz in the nuclear instrument.Oscillating circuit has two kinds of single arm type or push-pull types again.The oscillating circuit made from germanium transistor has efficient height, steady operation and other merits.But the high pressure generator output that is constituted that makes by a relatively large margin that parameter changes in the bigger temperature coefficient of germanium transistor and the use ageing process slowly changes in time.Just must be equipped with the voltage stabilizing circuit that has the sampling feedback in order to obtain more stable output.Though silicon transistor has the advantage that high back-pressure and low temperature float, its input characteristics changes very precipitous characteristics after conducting makes " oscillating circuit " that be made of it be difficult for starting of oscillation, and bigger starting oscillation current is arranged, and often presents labile state.Simultaneously, when the assemble compact high voltage source, also there is the contradiction of insulation and replacing fallible component.
Task of the present utility model makes above-mentioned high pressure generator be assembled into a small size easily, allow to overhaul more conveniently change fallible component, working stability, assembly that efficient is high.
The utility model high-pressure mini generator, it is characterized in that in common single arm type or push-pull type self-excited oscillation circuit, adopt silicon transistor, and the germanium diode of in its base stage feedback loop, connecting, particularly can be connected between feedback coil and the transistor base, can regard transistor and diode as a Darlington at latter event.The sealing in of this germanium diode alleviated silicon transistor greatly by being transformed in the saturation history by being transformed into conducting again, and the trend that base current sharply increases has been improved oscillating condition, thereby improved the stability and the efficient of oscillating circuit.
The utility model high-pressure mini generator, it is characterized in that the mixing of several custom-designed cordwood system type rectification units or several custom-designed cordwood system type two multiplication of voltage unit or above-mentioned two kinds of unit, superimposed in series formation voltage-multiplying circuit.This cordwood system type rectification unit comprises a rectifier diode and a high-voltage capacitance, and cordwood system type two multiplication of voltage unit comprise two rectifier diodes and two high-voltage capacitances, and they all make bluff body, and a pair of exit is respectively arranged on two bottom surfaces.In two exits on a bottom surface, have one to be shaped on an indenture, another has a projection, so that superimposed connection time identification and location.Be coated with the direction that a kind of color indicates rectification and voltage multiplier on the bottom surface of exporting exit having, and distinguish forward rectification and voltage multiplier and these two kinds of unit of negative sense rectification and voltage multiplier with different colours.This structure make the collection dress of high voltage source not only convenient, but also compact, both insulated reliably, be convenient to change fallible component again.
