Изобретение относитс к измерительной технике и может быть использовано дл измерени КПД и потребл емой механической мощности т гового генератора.The invention relates to a measurement technique and can be used to measure the efficiency and consumed mechanical power of a traction generator.
Известно устройство дл измерени мощности на валу двигател , которое содержит измерительный мост, первый и второй усилители , конденсаторный преобразователь частоты в напр жение, датчик частоты вращени вала и формирователь.A device for measuring motor power is known, which comprises a measuring bridge, first and second amplifiers, a capacitor frequency to voltage converter, a shaft speed sensor and a driver.
Измерительный мост включен своим входом в одну из фаз ротора, а выходом через первый усилитель св зан с вторым входом блока умножени . Конденсаторный преобразователь частоты в напр жение подсоединен через формирователь к датчику частоты вращени вала и к последовательно соединенным выходам блока умножени и делител напр жени через второй усилитель 1.The measuring bridge is connected by its input to one of the phases of the rotor, and its output through the first amplifier is connected to the second input of the multiplication unit. A capacitor-to-voltage converter is connected via a driver to the shaft speed sensor and to the series-connected outputs of the multiplier and voltage divider through the second amplifier 1.
К недостаткам таких устройств относитс низка точность измерени , обусловленна тем, что в них отсутствует блок моделировани механических потерь, которые не учитываютс при моделировании КПД мащины .The disadvantages of such devices include low measurement accuracy due to the lack of a mechanical loss modeling unit, which is not taken into account when modeling the mash efficiency.
Наиболее близким по технической сущности к предлагаемому вл етс устройство дл измерени мощности на валу электрической мащины, которое содержит электрически соединенные с электрической мап1и5 ной из.меритель активной электрической мощности и блок, моделирующий КПД мащины в функции ее тока нагрузки. Выходы измерител активной электрической мощности и блока, моделирующего КПД мащины,The closest in technical essence to the present invention is a device for measuring the power on the shaft of an electrical maschine, which contains electrically connected to an electrical matrix meter of active electrical power and a unit that simulates the efficiency of the maschine as a function of its load current. The outputs of the active electric power meter and the unit that simulates the efficiency of the maschiny,
10 подключены к входу множительного блока, выход которого соединен с одним входом блока алгебраического суммировани мощности , выполненного в виде уравновещенного моста. Регистрирующий прибор включен в одно из плеч моста, соединенного с пере 5 к.,1ючающими контактами. Другой вход блока алгебраического суммировани мощностей соединен с выходом блока моделировани .механических потерь мощности в машине в зависимости от скорости вращени ее10 are connected to the input of the multiplying unit, the output of which is connected to one input of the algebraic power summing unit, made in the form of a balanced bridge. The recording device is included in one of the shoulders of the bridge, connected to a pen 5 k., With 1 contacts. The other input of the algebraic power summing unit is connected to the output of the modeling unit. Mechanical power losses in the car, depending on its rotational speed.
