Problems solved by technology

[0002] At present, 10kV drop-out fuses are mostly used as protection on branch lines and distribution transformers of 10kV lines in rural power grids. Sometimes the protection cannot operate correctly, which makes the tripping rate of lines and the failure rate of distribution transformers remain high. At the same time, fault location takes time. longer

Abstract

The invention discloses a fiber current information transformer device applied to a 10-KV distribution network. The device comprises a current transformer, a current conversion and fiber driving module, a control host, a fuse control platform, a high-voltage power taking module, and a rectification module. The device has the following beneficial effects: the provided device is used based on cooperation with an agricultural network 10-KV circuit branch line and a 10-kV drop type fuse to realize high-cost-performance current signal collection of the agricultural network 10-KV circuit branch line; and with the high-voltage power-taking way, the CT coil way, and the fiber transmission way, the insulation requirement of the original 10-KV current transformer can be substantially reduced, the size can be reduced by two thirds, and the installation becomes convenient.

Description

technical field [0001] The invention belongs to the technical field of current signal acquisition of branch lines of 10kV power distribution lines in rural power grids, and in particular relates to an optical fiber current information mutual induction device applied to 10KV power distribution networks. Background technique [0002] At present, 10kV drop-out fuses are mostly used as protection on branch lines and distribution transformers of 10kV lines in rural power grids. Sometimes the protection cannot operate correctly, which makes the tripping rate of lines and the failure rate of distribution transformers remain high. At the same time, fault location takes time. longer. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an optical fiber current information mutual induction device which is easy to install and has a small volume and is applied to a 10KV distribution network. [0004] The technical solution adopt...
