Problems solved by technology

The existing independent probes on the market that can measure ns / μs high-voltage pulses mainly include Tektronix’s P6015A high-voltage probe (DC 20kV, pulse 40kV), Northstar’s PVM-5 high-voltage probe (up to DC 60kV, pulse 100kV) ; Among them, PVM-5 is an independent voltage probe with the largest range in the market, but for the application environment where the measured voltage amplitude is above 100kV, its withstand voltage level is still not high enough and there are limitations

Embodiment Construction

[0028] In order to describe the present invention more specifically, the technical solutions and related principles of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0029] Such as figure 1 As shown, an independent differential-integration high-voltage probe includes a high-voltage differentiator and a low-voltage integrator connected by a coaxial cable 7;

[0030] The high-voltage differentiator is used to differentiate the high-voltage signal of the high-voltage source, and transmits the obtained differential signal to the low-voltage integrator through the coaxial cable 7; the low-voltage integrator is used to integrate and restore the differential signal to obtain a low-voltage signal that is proportional to the high-voltage signal ( Same waveform as the high-voltage signal, with amplitude attenuation), for oscilloscope reading.

[0031] The high-voltage differentiator is a coaxial symmetri...

Abstract

The invention discloses an independent differential-integral high-voltage probe which comprises a high-voltage differentiator and a low-voltage integrator which are connected through a coaxial-cable. The high-voltage differentiator is an axisymmetric structure and comprises a shielding support, a cup-shaped sampling electrode and a rod-shaped high-voltage electrode. The low-voltage integrator is also an axisymmetric structure and comprises a housing and an integrating capacitor, integrating resistor and an impedance matcher which are installed inside the housing. By an independent differential cell design, the independent differential-integral high-voltage probe is applied more flexible and more freely in comparison with an integrated differential-integral system. In comparison with a present commercial independent probe, the independent differential-integral high-voltage probe has advantages of wider withstand voltage range which can be more than 200kV and smaller size due to a capacitor structure composed of a high-voltage electrode, an insulator and a sampling electrode. Meanwhile, as a compact integrator structure design is adopted, stray inductance of a loop is minimized, and excellent high-frequency response can be obtained.

Description

technical field [0001] The invention belongs to the technical field of pulse power, and in particular relates to an independent differential-integral high-voltage probe. Background technique [0002] Pulse power technology is to compress energy in space and time, and release a large amount of energy in a very short time to produce specific physical or chemical effects. Among them, the measurement and diagnosis of high-voltage electrical pulse signals is a very important part, which is of great significance to the output characteristics and operation status monitoring of the pulse system. [0003] The high-voltage probe is essentially a signal attenuator, which attenuates the input high-voltage signal so that the attenuated signal is within the withstand voltage range of the oscilloscope. When the attenuator has the same attenuation ratio for each frequency band, the attenuated signal waveform can be multiplied by the attenuation ratio to accurately restore the input high-vo...
