Clear regulations are also made on the aspects of operation of workers, safety fences, signboard hanging and the like in safety regulations, and the purpose is to effectively protect equipment and personnel safety. However, in a construction site, many workers have low safety awareness and often do not see safety warnings and do illegal operations by moving or crossing a safety fence without permission. For effective personnel safety protection, on one hand, the safety production consciousness of power personnel is enhanced, and the operation flow and the regulation in safety regulations are kept in mind; on the other hand, the performance of the electric power safety tool should be improved so as to effectively warn and protect workers. The electric power safety fence is one of safety tools which must be used in field work such as transformer substation construction, overhaul and the like, and the electric operation personnel and the live equipment can be ensured to keep enough safety distance by correctly using the safety fence, so that accidents caused by the fact that the operation personnel walk at wrong intervals are prevented.
