Abstract

A high-voltage current device, the invention includes a secondary coil, a shielding cover, an insulating medium, a casing, a base, a secondary coil terminal, an iron core, a primary coil, and a primary coil terminal, and its connection structure is: the primary coil passes through the core The two ends of the primary coil are connected to the terminals of the primary coil, and the terminal position of the primary coil is set on the upper platform of the high-voltage current device; the secondary coil is wound on the iron core, and the secondary coil is wound on the iron core. The coils of the coil are separated by insulating materials, and the layers of the secondary coil are also separated by the same insulating material. Outside the coil; the insulating medium is set between the shielding cover and the shell. The invention can be used for a high-voltage current booster or a high-voltage standard current transformer, and has the advantages of high insulation strength, compact structure and the like.

Description

technical field [0001] The invention relates to a high-voltage current device filled with an insulating medium, in particular to a high-voltage-resistant current booster or a high-voltage-resistant standard current transformer. Background technique [0002] In recent years, three-phase current transformers and three-phase voltage transformers have been widely used in power grids with a voltage level of 35kV and below. They are mostly used for large-scale users and special-purpose transformation gateways for energy metering and voltage monitoring of the power grid. The JB / T10432-2004 "Three-phase combined transformer" JB / T10433-2004 "Three-phase voltage transformer" industry standard implemented on August 1, 2004 stipulates the three-phase combined transformer and three-phase voltage transformer. Error test, temperature rise test and mutual interference test should be carried out under the condition of applying three-phase voltage and three-phase current. However, the detect...
