Transformer or reactor oil temperature detection and simulation device

Abstract

The invention relates to a transformer or electric reactor oil temperature detecting and simulating device which is characterized by comprising a multifunctional meter (G). A first detecting terminal (G-1) and a third detecting terminal (G-3) of the multifunctional meter (G) are connected with a first output terminal (ZK-1) and a third output terminal (ZK-3) of a function switch (ZK) respectively, and a second detecting terminal (G-2) and a fourth detecting terminal (G-4) of the multifunctional meter (G) are connected with a second output terminal (ZK-2) and a fourth detecting terminal (ZK-4) of the function switch (ZK). Trial proves that after the transformer or electric reactor oil temperature detecting and simulating device is used for carrying out oil temperature detection and defect overcoming on transformers or electric reactors of 220kV or higher-voltage transformer substations, the working efficiency is greatly improved, more importantly, due to the fact that defects are timely overcome, the accuracy of device monitoring is guaranteed, a reliable basis is provided for timely observing faults, and the safety benefits are obvious.

Description

technical field [0001] The invention relates to a transformer or reactor oil temperature detection and simulation device. Background technique [0002] At present, most substation transformers respond to temperature changes by outputting 4-20mA current or 100-150 ohm resistance. When the power failure detects the remote transmission function of the main transformer or reactor oil temperature gauge, it needs to be checked with the local monitoring machine. Since the temperature display of the local monitoring machine has a certain error, it is impossible to accurately check the data. During the operation of the transformer, when the dispatching master station and the local monitoring machine have temperature display errors, it is difficult to troubleshoot because the input source cannot be simulated. The closed system is put into a portable high-temperature furnace to gradually heat up, and the whole process takes 4 hours, which is extremely inconvenient. Contents of the i...
