Power transmission line electric power facility intelligent warning device based on self-excitation type power taking

Abstract

The invention discloses a power transmission line electric power facility intelligent warning device based on self-excitation type power taking, which comprises a shell. An LED display unit is arranged at the lower end of the shell, a solar cell panel is installed at the top end of the shell, and the solar cell panel is rotatably connected with the shell through a connecting assembly. A radar sensing unit, a rectifying and filtering unit, a buck-boost unit and an LED driving unit are arranged in the shell; the radar sensing unit is connected with the rectifying and filtering unit and senses that alternating-current voltage is converted into direct-current voltage after being rectified and filtered by the rectifying and filtering unit; the rectifying and filtering unit is connected with thebuck-boost unit and stabilizes the direct-current voltage at a preset voltage value; the buck-boost unit is connected with the LED driving unit, and the LED driving unit is connected with the LED display unit; the sensor is arranged on the shell and matched with the sound-light alarm device for warning and alarming, and meanwhile, the solar cell panel is adjustably arranged on the shell, so thatthe angle of the solar cell panel is conveniently adjusted, and the shell is shielded.

Description

Technical field: [0001] The invention relates to a line danger warning device, in particular to an intelligent warning device for transmission line power facilities based on self-excited power taking. Background technique: [0002] In recent years, with the development of science and technology, more and more electrical appliances have entered our lives, thus increasing the demand for electricity. Overhead power transmission lines cross with roads, power lines, and buildings, and the tower section of the cross span has caused a large number of line tripping faults due to foreign objects, construction and operations. According to statistics, external force damage is an important cause of line failures, such as accidental collision of cranes with wires, carts hitting poles, hanging wires, super-high vehicles accidentally touching wires, vehicle drivers and work electric shocks, etc., which have caused damage to facilities and tools many times. Even safety accidents such as ca...

Problems solved by technology

According to statistics, external force damage is an important cause of line failures, such as accidental collision of cranes with wires, carts hitting poles, hanging wires, super-high vehicles accidentally touching wires, vehicle drivers and work electric shocks, etc., which have caused damage to facilities and tools many times. Even safety accidents such as casualties, economic losses are also very serious

Traditional warning devices use red and yellow signs, which lose their effect at night; or simply flash, the display range is limited, and the warning effect cannot be achieved
