Abstract
Изобретение относитс к электроизмерительной технике и может быть использовано в автоматизированных стендах дл поверки и настройки счетчиков электроэнергии . Цель изобретени - повышение достоверности поверки. Эта цель в предложенном стенде, содержащем повер емый счетчик 1, эталонные источники 2 и 3 электропитани , контрольный ваттметр 4, а также оптико-электронные преобразователи 6 и 7, достигаетс за счет того, что в каждом канале усилени сигналов оптико-электронных преобразователей предусмотрены дифференцирующие цепочки 8,9, а в одном из каналов - инвертирующий усилитель 11, которые совместно с логическим элементом И 12 исключают формирование ложных импульсов счета на входе частотомера 13.2 ил.The invention relates to electrical measuring equipment and can be used in automated stands for checking and adjusting electricity meters. The purpose of the invention is to increase the reliability of verification. This goal in the proposed stand, which contains a rotatable counter 1, reference sources 2 and 3 of the power supply, control wattmeter 4, as well as opto-electronic converters 6 and 7, is achieved due to the fact that differentiating signals are provided in each channel for amplifying the signals of optical-electronic converters chains 8.9, and in one of the channels - an inverting amplifier 11, which, together with the logic element 12, eliminate the formation of false counts at the input of the frequency meter 13.2 Il.
