Embodiment Construction

[0030] The present invention will be described in further detail below in conjunction with the accompanying drawings and working principles, but it is not intended to limit the protection scope of the present invention.

[0031] The zinc oxide intelligent detection device of the present invention is independent of one body, and is connected to the ground wire in series with the arrester disconnector. When the arrester is damaged or the disconnector is damaged, it is only necessary to replace the damaged parts, because it is a separate installation even if the zinc oxide valve plate is heated. It will not affect the intelligent detection device, the battery is independently powered, and it is safe and reliable to charge with solar panels. It is safe and reliable to use the parallel connection method to prevent the intelligent detection device from being damaged. The use of the gapless arrester can isolate the ground current due to the closed circuit of the arrester, can detect w...

Abstract

The utility model relates to an intelligent detection device for a zinc oxide arrester, which comprises a connecting electrode, a resistor disc, a sheet electrode, a detection module, a current lead,a tubular electrode, a metal braising cover, an annular nut, a guide cover, a nut, a preset bolt, a shell, a solar panel, an antenna and a disconnector. The current lead is welded to the connecting electrode, bypasses the resistor disc and the sheet electrode, penetrates through a mutual inductance coil on the detection module and is connected to the tubular electrode, so that the current lead andthe resistor disc form a parallel wiring method, and a screw hole is reserved in the connecting electrode to adapt to zinc oxide arresters with various purposes, the leakage current, lightning strokefrequency and temperature of a zinc oxide arrester can be monitored on line, and the condition of the disconnector can be monitored. When overvoltage occurs, a fault point is found, a positioning function is realized, a grounding current generated due to the closed circuit of the arrester is isolated, the operation states of the zinc oxide arrester and the disconnector are monitored on line in real time, the power failure frequency is reduced, and rapid repair can be carried out.

Description

Technical field: [0001] The invention relates to an intelligent detection device for a zinc oxide arrester, in particular to an intelligent detection device which can detect the leakage current, the number of lightning strikes, the temperature and the remaining power of the zinc oxide arrester on-line to achieve real-time online detection of the operating state of the zinc oxide arrester. At the same time, it can detect whether the disconnector is good or bad. When the arrester suffers from overvoltage or the arrester is aging, the fault point can be found in time and the damaged parts can be quickly replaced to minimize the loss of power failure. Background technique: [0002] The existing surge arrester insulation testing products mainly include the following types. The first type has a mechanical pointer to display the leakage current of the zinc oxide arrester, which requires manual inspection and transcription of data. The size is large, and the detection product is co...
