Description

technical field [0001] The invention relates to a data transmission device, in particular to an intelligent capacitive data transmission device based on Zigbee technology. Background technique [0002] The so-called reactive power compensation means that after installing reactive power compensation equipment such as shunt capacitors in the grid, it can provide reactive power consumed by inductive loads, reducing the reactive power provided by the grid power supply to the inductive load and transmitted by the line. The flow of reactive power in the grid can reduce the power loss caused by transmission of reactive power in lines and transformers, and can also be used to adjust the voltage of the grid and improve the stability of the grid.

Problems solved by technology

[0003] Existing smart capacitor modules cannot upload data directly, it needs a controller with data upload function to realize it, and due to power limitation, the controller can only network with a limited number of smart capacitor modules, if the number of modules is too large, you need If there are multiple controllers, the cost will increase, and the data to be analyzed by the power distribution and transformation data terminal will become complex. If wired transmission is used, the transmission rate will be relatively low, and the greater the number of modules, the slower the networking speed will be. It takes a long time to identify the fault. The power distribution and transformation data terminal only reads the power quality parameters of the smart capacitor module at the previous moment, not the current power quality parameter. If there are more smart capacitor modules, it means that it needs to be transmitted If the amount of data is large, the real-time performance of uploaded smart capacitor data is poor. When there are many smart capacitor modules, the networking speed and data interaction are relatively slow. impact, the number of smart capacitor modules in the network is limited, and the communication protocols between smart capacitor modules are not uniform at this time
