Distributing transformer monitoring terminal set and use thereof

Abstract

The present invention relates to a power distribution and transformation monitoring terminal and its purpose belonging to the technical field of transformer monitoring equipment, which is suitable for operation monitoring of public transformers, special transformers and power distribution lines and is arranged on one side of a power transformer and comprises a CPU module, a power source sampling module, a modem module and a display module connected with each other. An input terminal of the CPU module is connected with an output terminal of the power source sampling module. An input terminal of the display module is connected with an output terminal of the CPU module. An output terminal of the CPU module can transmit operation data to a power distribution and transformation monitoring back-end through RS232 and RS485 communication line, the modem, a mobile network and a wire or wireless meter reading equipment. A high-speed microprocessor unit realizes scale conversion, greatly reduces complexity of peripheral circuits and collects and judges operation date of the power transformer detecting terminal device, thus ensuring lower cost and high performance / price ratio.

Description

technical field [0001] The invention relates to a distribution transformer monitoring terminal device and its application, which is suitable for operation detection of public transformers, special transformers and some power distribution lines. It belongs to the technical field of transformer monitoring equipment. Background technique [0002] Distribution transformers are power equipment that directly distribute electric energy to low-voltage users, and their operating data are an important part of the basic data of the entire distribution network. In urban and rural power grids, with the improvement of residents' living standards, the proportion of residents' load to the total load is increasing, and residents' requirements for power supply quality (such as voltage qualification rate, frequency, etc.) and power supply reliability are also getting higher and higher. When planning and designing power supply enterprises, they must have a good idea of ​​the current situation ...

AI Technical Summary

Problems solved by technology

Since transformers are surrounded by high-voltage areas, there is a certain degree of danger. Transformers are generally installed far away from the community. Before the transformer fails, the staff and the power supply department cannot understand its working status. State monitoring is very backward. Although some transformer monitoring devices also use digital modules or smart devices, the general circuit structure is complicated, the function is single, and the cost is high.
