Theintelligent terminal comprises a multisensor signal integration module, a data processing and calculating module, an energy-taking power supply module and a communication module, the multisensor signal integration module and the energy-taking power supply module are respectively connected with a temperature sensor, a vibration sensor and a partial discharge sensor which are arranged in the distribution transformer, and the energy-taking power supply module is of a current induction type and is arranged in the distribution transformer; and the multisensor signal integration module is connected with the data processing and calculating module, and the data processing and calculating module is in communication interconnection with the upper computer through the communication module. According to the invention, timely processing of data can be ensured, data redundancy is avoided, real-time evaluation of the operation state of the transformer, fault early warning and life evaluation can be realized, the reliability and safety of the distribution transformer are improved, and the reliability and safety of the whole power supply network are further improved.

Description

technical field [0001] The invention belongs to the technical field of power equipment state detection, and in particular relates to an intelligent terminal of a power distribution transformer and a working method thereof. Background technique [0002] In recent years, with the development of society and economy, the demand for electricity has been increasing, and users have higher and higher requirements for the quality of electric energy and the reliability of power supply. The distribution transformer is one of the most important electrical equipment in the power transmission and distribution system, and it is also one of the most managed equipment in the power supply department. At present, the working status of distribution transformers is affected by various factors such as temperature and partial discharge. At the same time, the distribution of distribution transformers is relatively scattered, resulting in the status information of distribution transformers cannot be...

Problems solved by technology

[0003] The existing detection of distribution transformers only collects and measures data on electrical quantities such as voltage and current. When an abnormal electrical quantity is found, the distribution transformer has already failed and cannot play the role of estimating the risk. Moreover, the existing detection The system only saves the operating data of the distribution transformer, but does not process and analyze the data of the distribution transformer, which will eventually cause data redundancy.
