Intelligent fault detection device for power transformer

Abstract

The invention discloses an intelligent fault detection device for a power transformer, which comprises a first shell, a connecting pipe, a second shell, a circuit board, a sound collector and a current detector, wherein a temperature sensor and a pressure sensor are arranged in the first shell, the first shell is connected with the second shell, the interior of the first shell is communicated witha transformer oil bin through a connecting pipe, a key module and a display screen are arranged on the upper end face of the second shell, the side end face of the second shell is provided with a first communication socket used for being matched with the sound collector, a second communication socket used for being matched with the current detector and a power socket, and the second shell is internally provided with a central processing unit, a comparison module and a database on a circuit board, and a data acquisition module, a converter and a data processing module which are in communication connection in sequence; and the central processing unit is electrically connected with the power socket and is in communication connection with the comparison module, the database and the data processing module. According to the invention, the fault of the transformer can be efficiently and quickly analyzed, and the detection efficiency of the transformer fault is greatly improved.

Description

technical field [0001] The invention relates to the technical field of transformer detection, in particular to a power transformer fault intelligent detection device. Background technique [0002] A power transformer is a static electrical device that is used to change an AC voltage (current) of a certain value into another voltage (current) with the same frequency or several different values; a power transformer is a power plant and One of the main equipment of the substation. The role of the transformer is multifaceted. It can not only increase the voltage to send electric energy to the power consumption area, but also reduce the voltage to the voltage of all levels to meet the needs of power consumption. During the maintenance of the transformer, the maintenance personnel often need to check the power transformer When the transformer fails, in addition to the current and voltage changes on each side of the transformer and the internal sound of the transformer, the oil, g...

The role of the transformer is multifaceted. It can not only increase the voltage to send electric energy to the power consumption area, but also reduce the voltage to the voltage of all levels to meet the needs of power consumption. During the maintenance of the transformer, the maintenance personnel often need to check the power transformer When the transformer fails, in addition to the current and voltage changes on each side of the transformer and the internal sound of the transformer, the oil, gas, temperature and other electricity in the transformer oil tank will also change; maintenance personnel need to check for various possible problems. Faults are checked one by one, the operation is cumbersome and time-consuming, and the efficiency of transformer fault repair is low, which greatly increases the recovery time of the power system and brings inconvenience to the production and life of enterprises and people; therefore, this application proposes a Power transformer fault intelligent detection device
