Description
Предметом изобретени вл етс устройство, посредством которого осуществл етс непрерывный автсматическик контроль величины со ротивленп заземлени нестацип парных электрических установо;-: (примен емых, например, на торфо разработках, при электропахоте ; т. п.) в их paбoчe состо нии и обеспечиваетс подача сигнала и отключающего пмиульса при превыщении сопротивлени заземлени заданной величины.The subject of the invention is a device, by means of which continuous automatic control of the value of the grounding of the nonstandard of paired electrical installations is carried out; -: (used, for example, in peat developments, with electrophore; etc.) in their working condition signal and disconnecting pmiuls when the grounding resistance exceeds a given value.
Контроль осуществл етс применением подключенного к сети переменного тока трансформатора, к средней точке вторичной обмотки которого присоедин етс заземл ющий контур, а разделенные на две группы заземлители присоедин ютс последовательно с полуобмотками реле минимального тока к зажимам вторичной обмотки трансформатора таким образом, что группы заземлителей оказываютс включенными параллельно в цепь заземлени ;i последовательно с землей в цепь вторичной обмотки трансформатора .The control is carried out by applying a transformer connected to the AC network, to the midpoint of the secondary winding of which a grounding circuit is connected, and the grounding conductors divided into two groups are connected in series with the undercurrent of the undercurrent relay to the secondary terminals of the transformer so that the grounding groups are turned on parallel to the ground circuit; i in series with the ground in the secondary circuit of the transformer.
