Design of portable backup UPS (uninterrupted power supply) added to tower lighting circuit

Abstract

The invention discloses a design of a portable backup UPS (uninterrupted power supply) added to a tower lighting circuit. The portable backup UPS comprises a box body, wherein the box body is of a rectangular structure; a main circuit board and a storage battery are arranged in the box body; a handle is arranged at the top of the box body; a cooling fan, state indicator lights, a startup button, ashutdown button, an input cable and an output cable are arranged at the side of the box body; a terminal plug is arranged at one end of the input cable; a terminal board faucet is arranged at one endof the output cable; one end, far away from the terminal plug, of the input cable and one end, far away from the terminal board faucet, of the output cable are connected to the main circuit board; the main circuit board comprises a first fuse, a main switch, a detection control circuit, a step-down rectifier circuit, a charging circuit, a boost inverter circuit, a first switch, a second switch and a second fuse; and the terminal plug is connected with the first fuse through the input cable. An emergency uninterrupted lighting power supply is provided, and the portable backup UPS is convenientto carry, good in economic benefit and simple in operation.

Description

technical field [0001] The invention relates to the technical field of tower lighting, in particular to the design of adding a portable UPS backup power supply to a tower lighting circuit. Background technique [0002] The country is currently vigorously developing the new energy industry. Megawatt-level large-scale wind turbines that can provide a large amount of clean and renewable energy have developed rapidly in my country, and tall wind turbines stand tall on the vast land of our country. Since the height of megawatt wind turbines exceeds 60 meters or even higher, the safety of personnel installing and maintaining at high altitude must be paid attention to. When constructing wind turbines, it is necessary to ensure the safety of personnel to go up and down the tower quickly and to escape from the tower quickly in case of emergency. . Climbing the tower is a necessary step during the installation and maintenance of the wind turbine, because the tower is a closed environ...

AI Technical Summary

Problems solved by technology

However, in case of an emergency or a power outage, when the wind turbine loses the power supply from the grid, the lighting of the tower will lose the source of power and cannot provide lighting, which affects the speed of people going down the tower and increases the danger of going up and down the tower.
