The subject matter herein pertains to a current transformer, comprising a secondary coil, connection contacts for establishing electrically conductive contact with the secondary coil from the outside, and a housing having a housing body and a housing head, wherein the secondary coil is accommodated in the housing body and/or is attached to the housing body, and the connection contacts of the secondary coil are provided on the housing head. According to one implementation, a connecting mechanism is provided, by means of which the housing head and the connection contacts can be mechanically or electrically conductively detachably connected to the housing body and to the secondary coil. A current transformer is therefore provided, which is cost-effective to produce and is flexible in terms of the use thereof.

Current converter with interchangeable head

The invention relates to a device for removably fixing a conductor () to a current transformer housing (), comprising a fixing element () which runs through a retaining element () lying on the current transformer housing () and which sits at least partly against the surface of the conductor () when the conductor () is fixed on the current transformer housing (). The invention is characterized in that the fixing element () runs around the circumferential surface of the conductor () in a looped manner when fixed.

Looped fastening element for removably fixing a conductor to a current transformer housing

A current measuring transducer for measuring the current flowing through an electrical cable, with a ring probe, a sensor and an evaluation device for recording the current value obtained by the ring probe and the sensor, wherein the ring probe has an annular core, wherein the ring probe is divided into a basic ring section and at least one movable ring section, wherein the movable ring section defines an open and a closed state, wherein in the open state, a radial cable insert opening is opened, and wherein a circularly closed arrangement is created in the closed state of the movable ring section in which the annular core surrounds the cable, wherein the radial insertion of a cable extending axially relative to the current measuring transducer into the inside area of the ring probe transfers the ring section from one to the other state, and measurement of the current in the cable inserted into the inside area is made possible in the closed state.

Current transformer

Systems and methods for detachable attachment of an electrical conductor to current transformer housing are disclosed. An illustrative device may [comprise] includes a current transformer housing, a holding element which is passed through the current transformer housing, and an attachment element which passes through the holding element, with the attachment element and/or the holding element resting at least partially on the surface of the electrical conductor when the electrical conductor is attached to the apparatus, the attachment element being rotatable about its longitudinal axis for attaching or releasing the electrical conductor. Moreover, the holding element may be rotatable about its longitudinal axis such that, in a first position, the holding element can be moved along its longitudinal axis for attaching or releasing the electrical conductor and, in a second position, the holding element cannot be moved along its longitudinal axis.

Apparatus for detachable attachment of an electrical conductor to a current transformer housing

The invention relates to a connection system for connecting a single-row housing () to a terminal element (), a terminal region () being provided on the single-row housing () for connecting the terminal element () to the single-row housing (), the terminal region () being connected to a printed circuit board provided in the single-row housing (). According to the invention, the terminal element () can be secured to the terminal region () by means of a plug contact ().

Connection system for connecting a single row housing to a terminal element

The invention relates to a device for detachably fastening a current conductor () to a current transformer housing () comprising a fastening element (), wherein the fastening element () can be guided such that the fastening element () at least partially contacts the surface of the current conductor () in a fastening state of the current conductor () on the current transformer housing (). The invention is characterized in that the fastening element () is implemented such that it performs a translatory displacement in the direction of the current conductor () when transitioning from an unfastened state to the fastened state of the current conductor () to the current transformer housing ().
