Description

multifunctional safety fence

technical field

The invention relates to the field of safety protection equipment in the electric power industry, in particular to a safety fence.

Background technique

At present, the installation of safety fences is one of the important technical measures to ensure the safety of on-site workers. The safety fence can not only prevent staff from entering live areas by mistake and ensure personal safety, but also effectively isolate live equipment and ensure the normal operation of electrical equipment and power grids. However, for a long time, the traditional fences used to ensure the safety of substation construction operations have no practical, safe and effective means of layout, and the warning function is often greater than the actual protection effect. question.

There are generally three types of traditional barriers in substations: wooden barriers, soft barriers, and hard barriers. During long-term use, the following disadvantages were found:

Wooden fence: mostly used indoors. The material is not corrosion-resistant and cannot be used for a long time. The shape is fixed, it is not easy to carry, and it is easy to be moved by the staff, so the safety of construction operations cannot be guaranteed.

Soft fence: mostly used outdoors. The main body of the pole is heavy, it is not easy to carry, and it is not easy to fix it on the concrete floor. When setting the warning tape, it takes a long time, and at least two or more people are required to complete it together, wasting a lot of manpower. In particular, the warning tape can be easily crossed, and it is very easy to enter the charged area by mistake, which cannot effectively protect it. In case of strong wind and thunderstorm, the pole is easy to be blown down, and the warning tape is easy to be scratched. In severe cases, the warning tape may be entangled with equipment and lines, causing major electrical safety accidents.

Hard fence: mostly used outdoors. The equipment is expensive and needs to be installed by a special person, and the installation is complicated, time-consuming and labor-intensive, and it is easy to be overtaken.

In view of these problems that arise during the use of the above-mentioned traditional barriers, they all seriously affect the safety of power equipment construction. In order to improve the safety and reliability of equipment construction, it is urgent to develop a new type of efficient and safe special fence.
