Abstract

The invention provides a power transformer state monitoring alarm device. According to the invention, an advanced GSM module technical is utilized, operation state information is sent out in the operation process of a power transformer, and the operation state information is transmitted far away through a GSM network; alarm message signals can be sent out in cases that the current or voltage of the power transformer deviate from rated values or open-phase and power-off accidents occurs, the alarm message signals are transmitted far away through the GSM network; and especially when the power transformer vibrates due to natural mechanical damages, manual mechanical damages or stolen accidents, the alarm message signals can be sent out and transmitted far away through the GSM network.

Description

technical field [0001] The invention relates to the field of power system equipment protection, in particular to a power transformer state monitoring and alarming device. Background technique [0002] A power transformer is a device that uses the principle of electromagnetic induction to change voltage and current. Power transformers are important equipment in power transmission lines, and their safe and stable operation is directly related to the national economy, the people's livelihood and the safe production of enterprises. The power transformer has a casing, and an iron core is arranged in the casing, and a primary coil and a secondary coil are wound on the iron core, and insulating oil for cooling is provided in the casing. [0003] The vast majority of power transformers are mostly placed on outdoor transformer platforms, especially the low-voltage power transformers that provide users with mains power are placed on outdoor unattended transformer platforms, with larg...
