Abstract

Inventia se refera la tehnica electrica de masurat, in particular la senzori inductivi de curent, care pot fi utilizati in contoarele electrice cu osingura si mai multe faze. Senzorul inductiv de curent, conform primei variante, include un corp, oinfasurare primara, ce contine doua bobine, si amplasata coaxial cu infasurarea primara o infasurare secundara, ce contine de asemenea doua bobine. Noutatea inventiei consta in aceea ca bobinele infasurarii primare sunt amplasate pe partea exterioara a corpului, iar bobinele infasurarii secundare sunt amplasate in interiorul corpului. Senzorul contine suplimentar un ecran executat din material electroconductibil si amplasat in interiorul corpului, deasupra infasurarii secundare. Iesirile bobinelor infasurarii secundare, acoperite cu o impletitura ecranata, sunt amplasate intr-un invelis tubular, totodata impletitura este conectata la ecran.Noutatea inventiei, conform celei de a doua variante, consta in aceea ca infasurarea secundara este executata in forma de cel putin o placa imprimata si este amplasata in interiorul corpului, totodata partea interioara a senzorului este umpluta cu compound.The invention relates to the electrical measuring technique, in particular to inductive current sensors, which can be used in electrical meters with osingure and several phases. The inductive current sensor, according to the first embodiment, includes a body, primary winding, containing two coils, and coaxially located with the primary winding a secondary winding, which also contains two coils. The novelty of the invention is that the primary winding coils are located on the outside of the body and the secondary winding coils are located inside the body. The sensor additionally contains a screen made of electroconductive material and located inside the body, above the secondary winding. The outputs of the secondary winding coils, covered with a shielded braid, are located in a tubular shell, at the same time the braid is connected to the screen. the plate is printed and is located inside the body, at the same time the inside of the sensor is filled with compound.
