A Transformer with Respiration Monitoring and Control Function

Abstract

The invention provides a transformer with breathing monitoring and control function. The respirator is equipped with a main air circuit; the main air circuit is provided with a drying chamber and an air control valve; air; when the transformer oil temperature drops, air is sucked through the main air circuit, and the sucked air passes through the drying chamber to dry the sucked air, and then enters the inside of the transformer; the processor is connected with the transformer oil temperature detection module to obtain the temperature of the transformer The oil temperature information in the running state is stored in the memory; at the same time, when the monitored oil temperature exceeds the preset threshold, the valve control circuit is connected to the air control valve to control the opening of the air control valve to make the transformer ventilate. The invention solves the problem that the breathing state of the transformer cannot be effectively monitored, realizes the monitoring of the breathing state of the transformer, and performs alarm processing when judging abnormal breathing, abnormal oil level and the like.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer with a breathing monitoring and control function. Background technique [0002] The transformer respirator is mainly used to dry and filter the air inhaled by the transformer. During the breathing process, more water will be produced. At the same time, after the rainy season, the respirator retains more water. When winter comes, the respirator will be blocked, causing difficulty in breathing for the transformer. A large pressure is generated, and when the temperature reaches a certain level, the respirator blocks the ice crystal and melts, and the internal pressure of the transformer is released instantaneously, causing heavy gas action and tripping. Contents of the invention [0003] In order to overcome the deficiencies in the above-mentioned prior art, the present invention provides a transformer with respiratory monitoring and control function, including:...
