Description

Transformer Monitoring System

technical field

The invention relates to the monitoring field of substations and transformers, in particular to a transformer monitoring system.

Background technique

Transformer is a device that uses the principle of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc. According to the purpose, it can be divided into: distribution transformers, power transformers, fully sealed transformers, combined transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric furnace transformers, rectifier transformers, etc. There are many types of transformers, so monitoring requires more This kind of scheme, it is difficult to realize networked remote monitoring.

Contents of the invention

In order to solve the problem that the transformer cannot be remotely monitored through networking, the present invention provides a transformer monitoring system.

The present invention is realized by adopting the following technical solutions: the transformer monitoring system includes a wifi wireless base station located in an open place near the substation, a substation monitoring terminal is provided near the substation, a transformer monitoring terminal is provided near the transformer, and user residents There is a user management terminal at the electric meter. The substation monitoring terminal includes a monitoring computer equipped with a wifi module. The transformer monitoring terminal includes a single-chip microcomputer. The single-chip computer is connected to a transformer load management terminal and is connected to a wifi module. The user management terminal includes a wifi module. user load management terminal.

When the transformer monitoring system is working, it sends and receives data through the wifi module on each terminal, and the added wifi wireless base station near the substation is used to establish a local area communication network for data transmission. Both the transformer load management terminal and the user load management terminal are existing equipment, the difference is that they are both equipped with a wifi module, and a monitoring computer equipped with a wifi module is added in the substation, and the user load management terminal has a unique code, which carries User information, collect user power supply and power consumption data, and then send the data to the transformer monitoring terminal. Specifically, the single-chip microcomputer of the transformer monitoring terminal collects all user data for analysis, and finally sends the results to the monitoring computer to calculate the overall power of the substation. Power supply, received power and line loss graphs, real-time display of regional power line loss information on the monitor computer screen. The above-mentioned collection of user power supply and power consumption data, data exchange, data storage, and power line loss information calculation methods are all existing technologies, and are easily realized by those skilled in the art.

The beneficial effects of the present invention are as follows: the use of arranged wifi wireless network to exchange data simplifies the difficulty of transformation, saves wiring costs, enables the transformer to be connected to the Internet of Things, facilitates monitoring, and can feed back data and faults in real time. The invention brings convenience to the data analysis of the power supply department, and the monitoring system based on the Internet of Things can realize rapid fault discovery and alarm; the whole system has low cost and strong practicability.
