| 摘要 |
The present invention relates to a device for current measuring in power supply networks comprising transformers for measuring current, a signal processing apparatus arranged on a printed circuit board and screw fastenings for mounting the device. The cable ducts of the transformers are orientated parallel to the plane of the printed circuit board, which has openings flush to the cable ducts, and the screw fastenings are fastening tabs with mounting holes, spaced so standards-compliant mounting is possible. In an alternate embodiment, the cable ducts are orientated perpendicularly to the plane of the printed circuit board, the screw fastenings are constructed as an angle rail with cable outlets and standards-compliant mounting holes, and the printed circuit board is internally fastened on one side of the angle rail. In another alternate embodiment the transformers are installed with the printed circuit board in a common housing with fastening tabs and standards-compliant mounting holes. |
