Multifunctional ultrahigh-frequency partial discharge sensing device

Abstract

The invention relates to a multifunctional ultrahigh-frequency partial discharge sensing device. The device comprises a shell, a first output port, a second output port, a signal coupler, a change-over switch and a signal conditioner, wherein the first output port and the second output port are arranged on the shell, the signal coupler, the change-over switch and the signal conditioner are installed in the shell, the signal coupler is used for acquiring ultrahigh-frequency partial discharge signals of high-voltage electrical equipment so as to obtain acquired signals, the change-over switch isconnected with the signal coupler, and is used for transmitting the acquired signals acquired by the signal coupler to the first output port or to the signal conditioner, and the signal conditioner is connected with the change-over switch and is used for receiving the acquired signals transmitted by the change-over switch, filtering and amplifying the acquired signals and then transmitting the acquired signals to the second output port. The device is convenient to carry, moreover, the effect that the same device can be applied to different types of detectors can be achieved, the working process is simplified, the operation risk is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention relates to the field of live detection of electrical equipment, in particular to a multifunctional ultra-high frequency partial discharge sensing device. Background technique [0002] In the partial discharge detection of high-voltage equipment, that is, partial discharge detection, UHF detection has a wide range of applications, which can be used as a means of inspection and precise detection. Various UHF PD products used for inspection and precise detection (qualitative, positioning) are increasing, which brings some problems: UHF PD detection products have a large number and variety, each with its own advantages and disadvantages. It is difficult to choose; in order to obtain good detection results, all UHF detection equipment suitable for various situations should be carried, but most of them are accessory equipment, which is time-consuming and laborious to carry, and different sensors need to be used for different detection hosts , ...
