Evaluation system for dynamic risk of operation of electric transmission and transformation equipment

Abstract

The invention discloses an evaluation system for dynamic risk of operation of electric transmission and transformation equipment. The evaluation system comprises a mounting pedestal; a transformer case is fixedly connected to the top of the mounting pedestal; a dynamic risk detection unit is fixedly installed at one side of the inner wall of the transformer case; and a top plate is fixedly installed at the top of the transformer case. A protection cover is fixedly connected at one side of the transformer case between the top of the mounting pedestal and the bottom of the top plate; electric fans are fixedly connected to the top and bottom of one side of the inner wall of the protection cover; and a control box is fixedly connected to one side of the top of the top plate. The invention relates to the technical field of electric equipment. With the evaluation system, the power maintenance work is carried out conveniently by the power staff; real-time dynamic risk assessment is carried out on the transformer; the liquid level and temperature of cooling oil inside the transformer can be detected in real time; and thus an objective of remote monitoring of the transformer is achieved.

Description

technical field [0001] The invention relates to the technical field of electric power equipment, in particular to an evaluation system for the dynamic risk of power transmission and transformation equipment operation. Background technique [0002] Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core. The main functions are: voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization, etc., which can be divided according to the purpose For: power transformers and special transformers, transformers are widely used in various large, medium and small substations, these transformers need to be filled with cooling oil when in use, so that the heat of the high voltage line inside the transformer can be dissipated well, And play a certain degree of insulation effect. [0003] At present, the cooling oil in the transformer will leak d...
