APPARATUS FOR DETECTING AND DETERMINING INTENSITY OF CORONA DISCHARGE AND ACCOMPANYING OVERHEATING OF INVESTIGATED REGION/OBJECT Russian patent published in 2020 - IPC G01R31/00 

FIELD: instrument engineering.

SUBSTANCE: invention relates to instrument making, in particular to devices intended for detection of crown or partial discharge, open flame, intended for detection and determination of corona/partial discharge intensity, and can be used for diagnostics of electrical equipment (overhead lines, contact network of railway transport, substations, detection of open fires). Disclosed device for detecting and determining intensity of corona discharge and accompanying overheating of the surveyed region/object comprises a visual channel made in the form of a visual camera with digital and optical magnification, thermal channel, which is a matrix with temperature sensitivity of 0.5 °C, receiving signal in spectral range of 7.5...13 mcm and configured to convert said signal into digital data, and a channel for recording corona discharge, which includes a quartz unit consisting of a quartz lens, an ionisation sensor mounted on a motor tube equipped with an electric motor for movement in a horizontal plane. At that, the holder tube is intended for movement of the sensor, thereby changing the angle of reception of UV radiation by separation/approach of the ionisation sensor to the inner part of the lens. Disclosed device also comprises a control system, to inputs of which are connected channel outputs, configured to correct total values of information signal generated by thermal channel, as well as a power supply unit, which outputs are connected to power consuming units of the device.

EFFECT: enabling processing, including in flight mode (altitude of 10 to 100 meters), data from three sensors of the device (thermal imaging, visual, recording of corona discharge) and transmission to a control panel with possibility of taking into account characteristics of the environment in places where measurement is taking place.
