Abstract

Изобретение относитс к электротехнике. Цель изобретени - повышение надежности и электробезопасности. Цель достигаетс введением в устройство рабочего 2 и дополнительного 4 коммутационных аппаратов, пульта 8 управлени , органа 9 дистанционного отключени , короткозамыкател 14, выполненного в виде трехфазного дроссел , а также органа 15 автоматического отключени . Упрощение системы и повышение надежности ее работы обусловлено тем, что она не содержит коммутаций в силовой цепи и св зана с работой устройств защиты от утечек тока на землю, предусмотренных в системе. 1 з.п. ф-лы, 2 ил.The invention relates to electrical engineering. The purpose of the invention is to increase reliability and electrical safety. The goal is achieved by introducing into the device a worker 2 and an additional 4 switching devices, a control panel 8, a remote disconnecting organ 9, a short-circuit switch 14 made in the form of a three-phase throttle, and also an automatic disconnecting organ 15. Simplification of the system and increase of reliability of its work is due to the fact that it does not contain commutations in the power circuit and is associated with the operation of devices for protection against leakage of current to earth provided in the system. 1 hp f-ly, 2 ill.
