Abstract

The invention discloses a high-precision Rogowski coil, which comprises an annular body composed of an ignition wire, an enameled wire, and a silicone tube arranged in order from the inside to the outside. The enameled wire is wound around the ignition wire, and the two ends of the ignition wire and the enameled wire are connected by joints, and compensation coils and lead wires are arranged in the joints. One end of each compensation coil is connected to the enameled wire, and the other end is connected to the lead wire. The ignition wire is provided with a flexible frame on the ring-shaped inner side, and a wire centering mechanism is fixedly arranged on the flexible frame. The invention can ensure that the central axis of the wire coincides with the central axis of the Rogowski coil bythe conical housing or the arrangement of the clamping rods arranged in a tapered shape, thereby avoiding the phase error. The new Rogowski coil of this design has improved a lot in position error andaccuracy, and is also very practical. The complexity of the structure does not increase the process flow compared to the Rogowski coil in the prior art, so the invention will be a qualitative breakthrough in power measurement, contributing to the power system.

Description

technical field

[0001] The invention relates to a high-precision Rogowski coil. Background technique

[0002] With the development of social economy, electric energy, as the main energy source in modern society, is more and more closely related to people's life and production and construction. With the rapid development of EHV and UHV power transmission and transformation technologies, the capacity and quantity of power equipment have increased significantly, and the scale of power grids has gradually expanded. The operation of the modern power system must not only ensure the quality of qualified power supply, but also ensure the stable and reliable power generation and power supply capacity. The power transformer is one of the most important equipment in the power system, and it is particularly important to improve the operation reliability of the power transformer. On-line monitoring of transformers can detect transformer faults in time and carry out early warning of acc...
