Transformer working state monitoring method

Abstract

The invention discloses a method for monitoring the working state of a transformer, which includes step 1: performing area numbering on low-voltage household transformers in different areas, and the number of areas can be several, and then performing a single item on multiple low-voltage household transformers in each area Numbering, different types of transformers can be distinguished by different numbering types, and multiple low-voltage household transformers in the same area are respectively connected to the main signal line in the same area by secondary signal lines to send data back to the database. This monitoring method The vibration amplitude acquisition technology and noise acquisition technology are used to detect the transformer, which improves the accuracy of fault diagnosis, and can analyze the fault type of the transformer in time. The transformer monitoring method is convenient for maintenance personnel to find transformers with potential safety hazards in time. Carry out systematic transformer data monitoring and analysis over a long period of time to ensure power supply security and improve power supply stability.

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 operation of the transformer.

[0003] At present, for the state monitoring of transformers at home and abroad, partial discharge monitoring, ultrasonic positioning, insulating oil chromatographic analysis and other technologies are mostly used to detect internal discharge and insulation conditions, but annual regular oil sampling cannot provide meaningful information for judging the real safety state of transformers. Information, in order to improve the security and stability of smart grid and the efficiency of grid equipment management, it is necessary to strengthen and enhance the monitoring capability of transformers
