Problems solved by technology

However, if the bus voltage contains large harmonic voltage components, it will also cause errors in the measurement results
[0007] In addition, these online monitoring systems currently excavate the ground at the substation site for cable wiring, which not only requires a large amount of construction work, but also damages the cleanliness of the substation ground

Abstract

The invention discloses a zinc oxide arrester online monitoring system which comprises a core processing circuit, a liquid crystal display circuit, a power supply, a real-time clock circuit, a sampling circuit and a communication circuit, wherein the liquid crystal display circuit, the power supply, the real-time clock circuit, the sampling circuit and the communication circuit are respectively connected with the core processing circuit. According to the zinc oxide arrester online monitoring system disclosed by the invention, the leakage current of the zinc oxide arrester is dynamically sampled, recorded and analyzed in real time, so that the insulating faults of the zinc oxide arrester can be found in the early stage, and the collected monitoring data is transmitted by way of various communication modes.

Description

technical field [0001] The invention belongs to the technical field of electric power, and in particular relates to an online monitoring system for a zinc oxide arrester. Background technique [0002] Transmission lines are responsible for the important task of transporting and distributing electric energy. The transmission line is a high-incidence area of ​​lightning disasters. Whether it is a direct lightning strike or an induced lightning strike, it may damage the transmission line equipment, and may also cause damage to the equipment connected to it. Therefore, the high-voltage transmission lines of the power system should be equipped with a complete set of lightning protection devices to ensure the safe operation of the transmission lines. [0003] Surge arrester is an important protection device to ensure the safe operation of the power system. After it is connected to the protected electrical equipment, it can limit lightning strike overvoltage or operating overvolta...
