Description

(5) УСТРОЙСТВО ДЛЯ БЕСКОНТАКТНОГО ИЗМЕРЕНИЯ ТОКА(5) DEVICE FOR CONTACTLESS MEASURING CURRENT

Изобретение относитс  к электр« измерительной технике и может бэ1ть использовано в тех случа х, когда требуетс  гальваническое разделение цепи измер емого тока от измерительного канала.The invention relates to electrical measuring equipment and can be used in cases where galvanic separation of the circuit of the measured current from the measuring channel is required.

Известны устройства дл  бесконтактного измерени  тока, содержащие магнитный модул тор в коробчатом экране, установленный внутри щупа, имеющего курковое устройство, которое позвол ет размыкать половины модул тора дл  введени  проводника с током в его окно 11.Devices for contactless current measurement are known, which contain a magnetic modulator in a box-shaped screen mounted inside a probe having a trigger device that allows opening half of the modulator to introduce a conductor with a current into its window 11.

Такие устройства обладают невысокой точностью и быстродействием.Such devices have low accuracy and speed.

Наиболее близким к предлагаемому  вл етс  устройство, содержащее магнитный модул тор, генератор возбуждени , выход которого подключен к модул ционной обмотке модул тора, реверсивный триггер, интегратор, выходной усилитель и эталонный резис тор, причем вход реверсивного триггера подключен к сигнальной обмотке модул тора, выход через интегратор в виде RC-цепи подключен ко входу усилител , выход которого через эталонный резистор подключен к компенсационной обмотке модул тора 2}.Closest to the present invention is a device comprising a magnetic modulator, an excitation generator, the output of which is connected to the modulation winding of the modulator, a reversing trigger, an integrator, an output amplifier, and a reference resistor, the input of the reversing trigger connected to the signal winding of the modulator through an integrator in the form of an RC circuit, is connected to the input of an amplifier, the output of which is connected via a reference resistor to the compensation winding of the modulator 2}.

Недостатком этого устройства  вл етс  низка  гранична  частота измер емого тока и св занна  с этим низка  точность измерени  быстро10 мен ющихс  токов.A disadvantage of this device is the low limiting frequency of the measured current and the associated low measurement accuracy of fast varying currents.

Цель изобретени  - повышение быстродействи  устройства и точности измерений в области высоких частот .The purpose of the invention is to increase the speed of the device and the accuracy of measurements in the high-frequency region.
