Description
Technical Field
The utility model relates to the technical field of electric power detection, in particular to a low-misjudgment partial discharge online tester based on gallium oxide.
Background
The partial discharge electrode weak arc detection system is used for detecting and analyzing the occurrence of arc and corona in a medium-high voltage system. At present, the arc detection mainly comprises various modes such as electromagnetic detection, ultrasonic detection, infrared detection and the like. However, these detection methods cannot be achieved simultaneously in terms of anti-interference capability, sensitivity, quantification capability and stability.
Through analysis, when an electrical appliance or a line generates ionization discharge, a corona discharge mode, a spark discharge mode or an arc discharge mode is mainly adopted. These methods all radiate ultraviolet rays having wavelengths in the range of 230nm to 400 nm. Sunlight also contains ultraviolet rays, but the ultraviolet rays with the wavelength less than 280nm are filtered by the ozone layer in the atmosphere, and the interval is called a solar blind area and is also called a solar blind area. The arc detection near the solar blind wavelength has the advantages which cannot be achieved by other detection methods.
The on-line partial discharge tester judges discharge test generation through detecting ultraviolet light in a solar blind area. The detector adopts a gallium oxide ultraviolet sensor as a partial discharge detection unit, and combines a two-way compensation technology, so that an ultraviolet light signal generated by discharge can be captured quickly when abnormal partial discharge occurs in an electric power facility, and the received ultra-weak ultraviolet light intensity signal is converted into a corresponding voltage signal and a corresponding current signal. The signal acquisition processing amplifying circuit is used for acquiring and processing signals of the double-path ultraviolet sensor, the signals are converted into ultraviolet light intensity data and alarm signals which can be quantized, and the connection between each acquisition unit and the platform data center is established by the Internet of things system to form a partial discharge detection alarm network.
The greatest advantage of the partial discharge electrode weak arc detection is the anti-interference capability, because no interference source exists in real life, and the only interference source, namely thunder and lightning, can be filtered through a correlation algorithm. In addition, the instrument also has the advantages of flexible installation and convenient integration: the installation is flexible, which means supporting various installation modes, such as supporting magnetic attraction, gluing, screw fixation and the like, and meanwhile, the device can be used by hands; the integration convenience means that the instrument has rich communication interfaces, such as supporting multiple transmission modes (RS485-IoT/2G/4G), and also provides multiple schemes for system integration.
The tester can be fixed in a position and carry out electric power detection to power equipment around, also can take and carry out portable type in hand and detect, and current tester often fixes the tester on a position, and is fixed insecure, and takes inconveniently, when external dust or water are more, can't protect tester itself.
