Abstract

The utility model provides a high voltage fast pulse measurement mechanism which comprises a coaxial line, a coaxial high frequency attenuator, an input connection part and an output connection part. A high voltage fast pulse enters the coaxial line through the input connection part and intactly outputs a high voltage fast pulse signal through the output connection part. The coaxial line has a capacitance voltage dividing function. An attenuated fast pulse signal is output by the coaxial line in a capacitance induction mode and enters the coaxial high frequency attenuator. The attenuated signal directly enters an oscilloscope for measurement. The high voltage fast pulse measurement mechanism provided by the utility model has the advantages that the coaxial line which has a capacitance voltage dividing function is used; the problems of signal distortion and high voltage breakdown in high voltage fast pulse measurement are solved; the mechanism is arranged at the corresponding position which needs monitoring in high voltage electrical and pulse high power studies; input and output connection parts are used for connection, thus high voltage fast pulse measurement and monitoring can be intactly carried out; and under the condition that the normal work of a device is not affected, the needs of measurement and monitoring are met.

A kind of measuring mechanism of high pressure fast pulse
Technical field
The utility model relates to a kind of measuring mechanism, particularly relates to a kind of measuring mechanism of high pressure fast pulse.
Background technology
In high-voltage electrical apparatus and high power pulsed ion beams technical research, relate to a large amount of high pressure fast pulses and measure.Common high-tension measurement adopts the electric resistance partial pressure mode, because the influence of its distribution parameter such as inductance, electric capacity, the serious distortion of the signal that makes this measuring method measure can not be satisfied the measurement requirement of high pressure fast pulse; The common on the other hand high frequency part device that declines can solve the distorted signals problem, but has the problem of high-voltage breakdown.
The utility model content
In order to overcome the problems referred to above, the utility model provide a kind of high pressure fast pulse measuring mechanism, can solve distorted signals and the high-voltage breakdown problem of high pressure fast pulse in measuring.
The utility model adopts following technical scheme: a kind of measuring mechanism of high pressure fast pulse, comprise coaxial cable and coaxial high frequency attenuator, input connecting portion and output connecting portion, the high pressure fast pulse enters coaxial cable and passes through the harmless output high pressure Fast-Pulse Measuring of output connecting portion through the input connecting portion; Described coaxial cable has the capacitance partial pressure function, and the Fast-Pulse Measuring of described coaxial cable after by the output attenuatoin of capacitive sensing mode enters coaxial high frequency attenuator, and the signal after decay directly enters oscilloscope measurement.
In technique scheme, the resistance value of described coaxial high frequency attenuator is 50 ohm.
In technique scheme, described coaxial cable and coaxial high frequency attenuator must be used in combination.
From architectural feature of the present utility model as can be seen, advantage of the present utility model is: adopted capacitor to divide the coaxial cable of compression functions, middle distorted signals and high-voltage breakdown problem that the high pressure fast pulse is measured have not only been solved, and be installed in and need the relevant position supervised in high-voltage electrical apparatus and the high power pulsed ion beams research, output input link connects, can nondestructively carry out the measurement and the supervision of high pressure fast pulse, also can under the condition that does not influence the equipment operate as normal, satisfy the needs of measuring and supervising.
Description of drawings
The utility model will illustrate by embodiment and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a structure principle chart of the present utility model;
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, the utility model is simple in structure, and can easily be installed in needs the relevant position supervised in high-voltage electrical apparatus and the high power pulsed ion beams research, and it is measured.
The high pressure fast pulse output of needs test is connected with input connecting portion of the present utility model, and the high pressure fast pulse enters coaxial cable through the input connecting portion, and coaxial cable of the present utility model has the capacitance partial pressure function; After the high pressure fast pulse entered coaxial cable, after the inductance effect, the high pressure fast pulse is almost harmless passed through the next stage applying unit that the input connecting portion outputs to the high pressure fast pulse.
And the high pressure fast pulse is when entering coaxial cable, because coaxial cable has the capacitance partial pressure function, produce a Fast-Pulse Measuring after the decay through the fast pulse after the inductance effect by the capacitive sensing mode, signal after the decay is imported coaxial high frequency attenuator, the resistance value of this coaxial high frequency attenuator is 50 ohm, and Fast-Pulse Measuring was advanced the coaxial high frequency attenuator voltage signal that can directly measure of back output of further decaying.
Testing tool can directly adopt oscillograph, and signal after tested can react the truth of high pressure Fast-Pulse Measuring to be measured really, avoids the distortion of signal, because test structure is simple, can take dual mode that target to be measured is tested simultaneously.
Mode one: the utility model series connection is entered in the circuit of measured signal, by oscillographic measurement can be real-time reaction circuit to be measured on the situation of high pressure fast pulse, provide reliable high pressure Fast-Pulse Measuring test data to the user.
Mode two: during for just in use equipment of target bit to be measured, because equipment can not stop, can directly hang over the utility model on the equipment outward, reflect measurement in the equipment use by oscillographic measurement to the high pressure Fast-Pulse Measuring, because this measurement does not need the work of arrestment, greatly facilitate operating personnel.
Disclosed all features in this instructions except mutually exclusive feature, all can make up by any way.
Disclosed arbitrary feature in this instructions (comprising any accessory claim, summary and accompanying drawing) is unless special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, unless special narration, each feature is an example in a series of equivalences or the similar characteristics.
The above only is preferred embodiment of the present utility model; not in order to restriction the utility model; all any modifications of within spirit of the present utility model and principle, being done, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
