Problems solved by technology

At this time, there is a certain air pressure in the oil chamber. On the one hand, this air pressure cannot be detected because there is no pressure monitoring device. On the other hand, it is difficult to observe whether there is gas inside due to the installation angle and height of the gas relay.

Abstract

The invention discloses a transformer on-load tap changer oil chamber pressure online monitoring system, comprising a detection module used for detecting the pressure of the oil chamber, a data collection module used for collecting detection data, a data transmission module used for transmitting the collected data, a data analysis module used for analyzing the collected data, a display module usedfor displaying the detection result, and an alarm used for issuing an alarm for abnormal values. The transformer on-load tap changer oil chamber pressure online monitoring system has the advantages of reasonable structure, convenient operation and easy monitoring, and has high promotion and application values.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an on-line pressure monitoring system for an oil chamber of a transformer on-load tap changer. Background technique [0002] The on-load tap-changer is mainly to adjust the transformer tap with load, so that the output voltage of the transformer meets the required standard, and every time the tap-changer adjusts the voltage, the two contacts will be bridged through the transition resistance, and this process will inevitably lead to pull The arc discharge will generate local high temperature, and the high temperature will cause the oil in the oil chamber to undergo a chemical reaction to generate gas. Frequent load changes will lead to multiple adjustments in the voltage, further forcing the on-load tap-changer to perform multiple switching actions, and the local high temperature will cause the oil in the oil chamber to decompose again. In this way, various gases will slowly...
