Изобретение относитс к автоматике и измерительной технике и может быть использовано дл обнаружени поврежденного участка в разветвленных распределительных кабельных сет х напр жением 6-20 кВ.The invention relates to automation and measurement technology and can be used to detect a damaged section in a branched distribution cable network with a voltage of 6-20 kV.
Известны устройства дл определени поврежденного участка электрической сети, содержащие датчик тока, выпр митель, реагирукх ий ор ган и индикатор D.Devices are known for detecting a damaged portion of an electrical network, comprising a current sensor, a rectifier, a response body and an indicator D.
Однако эти устройства не обеспечивают безопасность обслуживающего персонала,- так как датчики тока включены непосредственно в цепи высокого напр жени , краме этого,крнструкци их очень громоздка .However, these devices do not ensure the safety of service personnel, since current sensors are directly connected to high voltage circuits, the cracks of this, and their construction is very cumbersome.
Наиболее близким к предлагаемому изобретению вл етс устройство дл определени поврежденного участка электрической сети. Это у;тройство содержит датчик тока, выполненный в виде быстронасыщающегос и ненасыщающегос трансформаторов тока.Closest to the proposed invention is a device for determining a damaged section of an electrical network. This device has a current sensor, made in the form of fast-sapping and non-satiating current transformers.
каждый из которых подключен через выпр митель к одной из обмоток реагирующего элемента. Первичной обмоткой обоих трансформаторов токг служит токопровод линии. В этом устройстве имеетс индикатор срабатывани , который автоматически возвращаетс в первоначальное состо ние 2 .each of which is connected via a rectifier to one of the windings of the reacting element. The primary winding of both current transformers is the conductor of the line. In this device, there is a trigger indicator that automatically returns to the initial state 2.
Недостатками этого устройства Disadvantages of this device
10 вл ютс низка надежность электроснабжени потребителей и повышенна опасность дл обслуживающего персонала при вы влении и определении поврежденного участка высоковольтной 10 are low reliability of power supply of consumers and increased danger for the staff when identifying and determining the damaged section of high voltage
