Description
Изобретение относитс к электрои мерительной технике и может быть ис пользовано при испытани х высоко-. вольтных выключателей в режиме отключени ненагруженных (холостые) л ний. ; По основному авт. св. N известно устройство дл испытаний .. выключателей на отключение зар дного тока,содержащее последовательно соединенные батарею конденсаторов, элемент включени и реайтор, образующие колебательный контур промышленной частоты, конденсатор, имитирующий отключающую линию, который св зан с указанным контуром и блоко питани посто нного тока, первый дополнительный реактор и RC-цепочку подключенные между собой параллельн и включенные между батареей конденсаторов и блоком питани , второй до полнительный реактор и отключающий элемент, например предохрани.тель, подключенные взаимно параллельно и включенные в колебательный контур между батареей конденсаторов и реактором 111 Недостаток известного устройства - искажение формы кривой отключаемого тока в испытуемом выключателе высшими гармониками в одном из нормируемых режимов (в режиме отключени ). Цель ийобретени - повышение точности испытаний путем воспроиЗведе-. ни реальной формы кривой отключаемого тока. Эта цель достигаетс тем, что в известное устройство введен компенсирующий реактор, включенный последовательно сбатареей конденсаторов. На чертеже приведена схема предлагаемого устройства. Устройство содержит конденсатор 1, имитирующий отключаемую линию,блок 2 питани посто нного тока, испытуемый выключатель 3, элемент включени , батарею 5 конденсаторов, первый дополнительный реактор 6, реактор 7The invention relates to electrical measuring technique and can be used in high test cases. Voltage switches in off mode unloaded (idle) lniy. ; According to the main author. St. N is known a device for testing .. switches for disconnecting the charging current, containing a capacitor battery connected in series, a switching element and a reitor, forming an industrial frequency oscillating circuit, a capacitor imitating a disconnecting line which is connected to the indicated circuit and a DC power supply unit, the first additional reactor and the RC chain are connected in parallel between them and connected between the capacitor bank and the power supply unit, the second additional reactor and the disconnecting element, on Example predohrani.tel connected mutually in parallel and incorporated in the oscillation circuit between the capacitor battery and reactors 111 A disadvantage of the known device - distortion curve of the interrupted current in the test circuit breaker higher harmonics in one of the standardized modes (in disconnected mode). The goal of the invention is to increase the accuracy of tests by reproducing. nor the real shape of the current to be cut. This goal is achieved by the fact that a compensating reactor, connected in series with a battery of capacitors, is introduced into a known device. The drawing shows a diagram of the proposed device. The device contains a capacitor 1 that simulates a disconnecting line, a DC power supply unit 2, the test switch 3, an switch element, a capacitor bank 5, the first additional reactor 6, the reactor 7
