Оценка профессионального риска по фактору «электрическое поле промышленной частоты»

Abstract

В статье приведены результаты расчета величины профессионального риска по фактору «электрическое поле промышленной частоты» для персонала Центрального (ранее Ханты-Мансийского) предприятия магистральных электрических сетей. Расчет выполнен на основе логико-вероятностной модели вероятности повреждения здоровья работников. Вероятности некоторых событий логико-вероятностной модели были определены на основе данных, полученных в результате экспериментального исследования распределения напряженности электрического поля на открытых распределительных устройствах подстанций напряжением 500 кВ, указанного предприятия. Для учета вреда, наносимого пребыванием в зонах различной напряженности электрического поля, были использованы специальные коэффициенты, определенные на основе кривой предельно допустимого времени нахождения в электрическом поле промышленной частоты. Сделаны выводы о факторах, определяющих величину профессионального риска для персонала, обслуживающего электроустановки сверхвысокого напряжения. The article presents the results of calculation of the professional risk value from the factor “electric field of industrial frequency” for the personnel of the Central (formerly the Khanty-Mansiysk) Main Power Transmission Line Company (PMES). This calculation was performed using the logical-probability model. The probability of certain events of this model were determined based on data derived from experimental studies of the electric field distribution on the open distribution 500 kV substations, of the company mentioned earlier. Special coefficients have been used to account the harmful effects for human present in areas of varying electric field. Special coefficients have been determined on the basis of the curve of maximum allowable time spent in the electric field of industrial frequency. The author points out the factors that determine the professional risk to personnel operating extra high voltage electrical equipment.
