Description

Изобретение относитс  к электроI автоматике, обеспечивактей успешный самозапуск синхронной нагрузки после кратковременного перерыва литани  при действии автоматического включени  резерва (АВР). Известно устройство опережающего гашени  возбуждени  двигателей (СЩ) в цикле АВР, при достижении заданной разности частот напр жений двух источников питани  действует с перво в ддержкой времени на пуск схетны ресинзфоннзации, а со второй вьодержкЬй врембнн - на рткхввчение рабочего ввс«а||13.The invention relates to electrical automation, ensuring successful self-starting of a synchronous load after a short lithium interruption under the action of an automatic switch on reserve (ATS). It is known a device for the advance quenching of motors (SS) in the ATS cycle, upon reaching a predetermined frequency difference between the voltages of the two power sources, acts, first time, to start the resinfusion circuit, and from the second time on the air force to work.

Данное .устройству на реле частоты и реле времени не пр1вдотвращает несинхронное восстановление питани  двигателей с непогашенным полем.This device for a frequency relay and a time relay does not prevent the asynchronous restoration of power supply to motors with an unpaid field.

Наиболее близким к предложенному  вл етс  устройство, содержащее фазочувствительный блок, два входа которого предназначены дл  подключени  к одноименным выходам датчиков напр жени  независимых источников, и исполнительные блоки дл  каждой сек . ции потребител  с злектродвйгател ми 2j. .The closest to the proposed is a device containing a phase-sensitive unit, two inputs of which are intended to be connected to the same output of voltage source sensors of independent sources, and execution units for each second. Consumers with 2v power consumers. .

Однако устройство может срабатывать ложно при неисправност х датчйка напр жени  (ДН) или других несимметричных режимах в питеиощей сети вследствие возникающего сдвига фазы напр жений. .However, the device may malfunction when the voltage sensor (DN) malfunctions or other asymmetrical modes in the power supply network, due to the resulting phase shift of the voltages. .

Цель изобретени  - повышение надежности работы устройства, его селективности и повышение устойчивости сингфонных двигателей. .The purpose of the invention is to increase the reliability of the device, its selectivity and increase the stability of single-ended engines. .
