Transformer working state monitoring method

Abstract

The invention discloses a transformer working state monitoring method. The method comprises the following steps: low-voltage user connecting transformers in different areas are subjected to area numbering, wherein a plurality of areas can exist; multiple low-voltage user connecting transformers in each area are then subjected to single item numbering; different types of transformers can be distinguished by adopting different number types; and the multiple low-voltage user connecting transformers in the same area are connected to a total signal line in the same area by sub-signal lines to transmit data back to a database. The monitoring method uses a vibration amplitude acquisition technology and a noise acquisition technology to detect the transformer, the fault diagnosis accuracy is improved, the fault type of the transformer can be analyzed timely, and according to the transformer monitoring method, a maintenance personnel can timely find out a transformer with potential safety hazards, monitoring and analysis on the transformer data in the system can be carried out in a long time, power supply safety is ensured, and power supply stability is improved.

Description

technical field [0001] The invention relates to the technical field of power systems, in particular to a method for monitoring the working state of a transformer. Background technique [0002] With the improvement of people's living standards, the requirements for the power industry are increasing, and it is hoped to obtain power services with qualified voltage quality and uninterrupted power supply. Therefore, it is the responsibility of every power worker to improve the quality of power supply and ensure the power supply time. Transformer is an important power supply equipment. Traditional transformers are mostly erected on wire poles. Although they have protective casings, they have been eroded by the external environment for a long time, which will still affect the normal operation and service life of the transformer. More and more box-type transformers are used in the power industry. This kind of box-type transformer has a simple structure, lacks monitoring settings, a...

Transformer is an important power supply equipment. Traditional transformers are mostly erected on wire poles. Although they have protective casings, they have been eroded by the external environment for a long time, which will still affect the normal operation and service life of the transformer.

More and more box-type transformers are used in the power industry. This kind of box-type transformer has a simple structure, lacks monitoring settings, and lacks monitoring of the working status of the transformer. At the same time, the internal temperature and humidity of the box-type transformer will affect the operat
