Abstract

FIELD: electric engineering. SUBSTANCE: device has capacitor battery which is switched by commutator. Part of battery is by-passed by serial circuit of resistor and high-speed commutator which operation time is in range of several milliseconds. switching control input of commutator receives through logical unit a signal from detector in circuit of by-pass capacitor battery about its switching off. Said high-speed commutator is designed using either thyristors or vacuum with ignition of spark gap. EFFECT: increased reliability due to autonomous decrease of voltage on capacitors and switch when device is switched off.

Изобретение относится к электротехнике и может быть использовано на подстанциях с шунтовыми конденсаторными батареями. Цель: повышение надежности работы устройства в результате автономного снижения напряжения на конденсаторах и на выключателе при отключении устройства. Устройство представляет собой коммутируемую выключателем конденсаторную батарею, часть которой шунтирована резистором с включенным последовательно с ним быстродействующим замыкателем, имеющим время включения порядка нескольких микросекунд. На вход управления включением замыкателя через логический блок подается сигнал от датчика в цепи ШКБ о факте ее отключения. Указанный быстродействующий замыкатель может быть выполнен тиристорным или вакуумным с поджигом искрового промежутка.The invention relates to electrical engineering and can be used in substations with shunt capacitor banks. Purpose: improving the reliability of the device as a result of autonomous reduction of voltage across capacitors and on the circuit breaker when the device is turned off. The device is a capacitor bank switched by a switch, part of which is shunted by a resistor with a high-speed contactor connected in series with it, having a turn-on time of the order of several microseconds. A signal from the sensor in the ShKB circuit about the fact of its disconnection is fed to the input for controlling the closing of the contactor through a logic unit. The specified high-speed contactor can be made thyristor or vacuum with ignition of the spark gap.
