Distribution transformer running monitoring device

Abstract

The invention relates to a distribution transformer running monitoring device, is widely applied to fault monitoring of transformers of electric systems, early warning before the event and inquiring after the event, and belongs to the technical field of electric power engineering. The distribution transformer running monitoring device comprises a central control box and six pincer-like current andvoltage mutual inductors, wherein the central control box is mounted above a transformer; the six pincer-like current and voltage mutual inductors are arranged on the outside of the central control box; high-voltage coil leads and low-voltage coil leads of three windings of the transformer separately penetrate through the six pincer-like current and voltage mutual inductors; a camera which is used for implementing remote observation and photographing abnormal appearance of the transformer is mounted on the top of the central control box; a transmitting system is mounted in the central controlbox and comprises a battery, a video module and a current monitoring module; the video module and the current monitoring module both communicate with a communication module, and the communication module transmits data acquired through an antenna to a far-end master controller. Real-time distribution transformer monitoring can be realized, the daily operation and maintenance management efficiencyof a distribution transformer is improved, and the labor resource costs are reduced.

Description

technical field [0001] The invention relates to a distribution transformer operation fault monitoring device, which is widely used in power system transformer fault monitoring, pre-warning and post-event query, and belongs to the technical field of electric power engineering. Background technique [0002] At present, the monitoring of faults such as internal windings of distribution transformers generally relies on relay protection systems to detect faults by analyzing the changes in current and voltage parameters of the entire branch circuit. The situation that the electric transformer is directly burned. [0003] Therefore, there is an urgent need for a distribution transformer operation monitoring device that can quickly detect transformer faults and reduce the probability of serious damage to the transformer. Contents of the invention [0004] The object of the present invention is to solve the deficiencies in the prior art, and provide a low-cost distribution transfo...
