Abstract

A cable terminal hot-line work risk evaluation method based on a human body surface electric field is characterized by comprising the following steps that 1, a standard human body model is built based on human body average parameters in cable terminal hot-line work, and a cable terminal tower model is built based on actual engineering parameters; 2, simulating human body electric field distribution through electromagnetic field simulation based on an actual operation mode, an operation entering mode and an operation posture, and calculating human body electric field distribution data; and step 3, establishing a safety risk evaluation standard, judging the human body electric field distribution data based on the standard, and prompting an operation risk level. Based on the method provided by the invention, the human body surface electric field can be accurately simulated when the cable terminal is in hot-line work, so as to ensure that the electric field and electromagnetic exposure level of a worker in hot-line work is within the minimum value which can be borne by the human body, thereby improving the safety of hot-line work.

Description

technical field [0001] The invention relates to the field of safety production risk management, and more specifically, to a risk assessment method for live work at a cable terminal based on an electric field on the surface of a human body. Background technique [0002] Risk management is a research topic that has been attached great importance to in safety production in recent years. Its essence is to eliminate various disaster consequences caused by risks in the most reasonable way. It includes a set of systematic and scientific management methods such as hazard identification, risk evaluation, and risk control. . Risk management includes identification of dangerous points, identification of potential safety hazards, assessment of the risk level of each hazard, comprehensive analysis of the severity and possibility of safety accidents, and identification of hidden dangers that must be improved for rectification and inspection. Improve and continuously reduce security risks...
