Intelligent data acquisition series-parallel anti-icing gap lightning arrester

Abstract

The invention relates to the field of lightning arresters, in particular to an intelligent data acquisition series-parallel anti-icing gap lightning arrester, which comprises: an upper crimping fitting and a discharge fitting; and a glass fiber rod, wherein an annular winding upper electrode, an annular resistor disc and an annular winding lower electrode are arranged on the glass fiber rod. The annular winding lower electrode is connected with a discharge connecting rod; the discharge connecting rod is connected with a series gap discharge ball and a parallel gap discharge ball; the bottom end of the glass fiber rod is connected with a discharge fitting, and the top end of the glass fiber rod is connected with an upper crimping fitting; and the upper crimping fitting is provided with a solar anti-icing umbrella, and the solar anti-icing umbrella is connected with an anti-off fitting. The outer surfaces of the discharge fitting, the glass fiber rod, the annular winding lower electrode, the annular resistor disc, the annular winding upper electrode and the upper crimping fitting are provided with an outer sleeve umbrella skirt through injection molding. The lightning arrester is reasonable in design, simple to install, low in investment and operation maintenance cost, and capable of effectively preventing lightning, rain, snow, ice flashover and heavy lightning impulse and monitoring faults in real time, and ensures normal operation of a distribution network line.

Description

technical field [0001] The invention relates to the field of arresters, in particular to an intelligent data acquisition series-parallel anti-icing gap arrester. Background technique [0002] In recent years, power development has focused on improving power security capabilities. However, in mountainous areas with complex terrain, micro-topography and micro-climate, there are thousands of faults and defects of distribution network lightning arresters every year, and most of them are caused by lightning strike faults. 70-80%, especially in winter rainy and snowy weather, the line is covered with ice and off-line, and the lightning strike amplitude is too large to cause the arrester to fail, and the arrester cannot be found and replaced in time. [0003] Therefore, solving the icing of arresters, line off-line and real-time status of arresters is the top priority that must be solved for distribution network lines at present.

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an intelligent data acquisition series-parallel anti-icing gap arrester, which solves the problem of ice-covered flashover tripping faults of the arrester in areas with harsh environments, and solves the problem of increased ice-covered weight of lines and excessive wind force. The problem of off-line and disconnection also solves the problem that the arrester failure cannot be monitored in complex environments
