A high voltage warning device

Abstract

The invention discloses a high-voltage warning device, which comprises a plurality of hanging fixing clips arranged on the high-voltage line, a warning light connected under the high-voltage line through the hanging fixing clips, a first damper and an auxiliary line; one end of the warning light is connected to the second One hanging clip is connected, the other end is connected to the turnbuckle screw through the first damper; the other end of the turnbuckle screw is connected to the auxiliary line, and the other end of the auxiliary line is connected to the second hanging clip on the high-voltage line through the second insulating terminal The warning device also includes a shunt line; one end of the shunt line is connected to the connection between the warning light and the first damper, and the other end is connected to the connection between the first insulating terminal and the turnbuckle. The warning light of the present invention is powered by a voltage difference through an auxiliary line, has simple structure, low cost, environmental protection and energy saving; and can resist harsh environments on high-voltage lines, is safe and reliable, and is suitable for popularization and use.

Description

technical field [0001] The invention relates to a warning device, in particular to a high-voltage warning device. Background technique [0002] In order to realize the long-distance transmission of electric energy, high-voltage lines are generally used for transmission at present, and high-voltage lines can be seen everywhere in modern life. Although high-voltage lines facilitate power transmission and greatly reduce power loss, they bring potential high-voltage dangers, and electric shock accidents due to high-voltage lines occur frequently every year. Especially if the aircraft hits a high-voltage line, huge casualties will occur. In order to avoid electric shock accidents on high-voltage lines, people have adopted a variety of warning methods, which can be roughly divided into four types: hanging warning signs, warning through cameras, warning by electromagnetic field induction and warning with lights. [0003] Although hanging warning signs can play a certain warning r...

Problems solved by technology

[0003] Although hanging warning signs can play a certain warning role, the effect is still greatly limited, and the warning effect at night is almost zero; manual control intervention is required through camera, and the effect is limited and labor-intensive in actual use; through electromagnetic field induction It warns of electromagnetic interference and false alarms; the effect of using light warning at night is obvious, but most of the products now provide power for the warning lights by installing batteries and solar panels on high-voltage transmission lines. The structure of the product is complex, the cost is high, and there are restrictions on the use of power; and because it is used on high-voltage lines, the environment is very harsh, rain, snow, wind and frost, and strong current and strong magnetic field, so its reliability cannot be guaranteed due to structural limitations.
