Technical Field
[0001] The utility model relates to the technical field of circuit breaker feeder terminals, in particular to an intelligent feeder terminal with dual output power supplies. Background Art
[0002] At present, various feeder terminals (abbreviated as FTU) have been widely used. However, the old feeder terminals only use the main line for power supply, and cannot handle emergency situations when encountering power outages. Although some new feeder terminals have backup power supplies, due to unreasonable power distribution, the equipment starts abnormally or restarts abnormally during operation; and when a sudden fault causes power outage, the abnormal data cannot be recorded and saved in time, and effective data cannot be provided for subsequent analysis of the cause of the fault. Summary of the invention
[0003] The purpose of the utility model is to solve the problems existing in the above-mentioned prior art and to provide an intelligent feeder terminal with dual output power supplies.
[0004] The specific scheme of the utility model is: an intelligent feeder terminal with dual-output power supplies, including a box body and a main power supply. A solar panel is also arranged outside the box body, and the electric energy generated by the solar panel is incorporated into the main power supply. A backup power supply, a power control module, a power board, a main control board, a signal acquisition board, and a liquid crystal display board are installed in the box body. The backup power supply has energy storage and power supply functions. The main power supply is transmitted to the power board after passing through the power control module. The power board distributes the power to the main control board, the signal acquisition board, and the liquid crystal display board for use after processing. The power control module is provided with a detection unit, and the detection unit is used to monitor the power supply status. When the main power supply has surplus power, the power control module distributes part of the electric energy to the backup power supply for energy storage; when the main power supply is insufficient, the power control module controls the backup power supply to supply power to the power board.
[0005] Furthermore, the power control module includes an input / output monitoring unit, which is used to monitor the input and each output in real time and automatically adjust the output ratio of each output to reasonably distribute electrical energy without affecting the normal operation of the equipment while storing energy in the backup power supply.
[0006] Furthermore, the power control module includes an undervoltage / overvoltage protection unit. When the supply voltage is higher or lower than the warning value, the power control module sends an alarm to the superior control. When the voltage is higher or lower than the limit value, the power control module enters a protection state. After the supply voltage is normal, the power control module automatically releases the protection.
[0007] Furthermore, the power control module includes a battery start-stop, activation unit and a compatible AC / DC input unit to facilitate autonomous selection of the working state of the backup power supply and extend its service life; the compatible AC / DC input unit is used to enable the power board to adapt to different power supply modes.
[0008] Furthermore, the power control module is provided with a communication unit, and the communication unit is used to communicate with the main control board to achieve remote control and data uploading.
[0009] Furthermore, the main control board is provided with a storage unit to save the data monitored in case of sudden failure.
[0010] Furthermore, a super capacitor module is provided on the power board, and the super capacitor module is used to keep the device working normally for a period of time when the power supply is interrupted due to a sudden fault.
[0011] The utility model has the following beneficial effects: solar panels are set up and incorporated into the main power supply, which can save energy and also play a certain backup role. In the face of short-term emergencies, supercapacitors can provide short-term battery life. In the face of urgent emergencies, the backup power supply can be enabled to provide longer battery life. A variety of protection units are provided to effectively protect the normal power supply of equipment, and a plurality of monitoring units are provided to reasonably allocate electrical energy. Communication and storage units are provided to upload monitoring data in real time and to save data monitored in the event of sudden failures. BRIEF DESCRIPTION OF THE DRAWINGS

The backup power supply has energy storage and power supply functions. The main power supply is transmitted to the power board after passing through the power control module. The power board distributes the power to the main control board, the signal acquisition board, and the liquid crystal display board for use after processing. The power control module is provided with a detection unit, and the detection unit is used to monitor the power supply status. When the main power supply has surplus power, the power control module distributes part of the electric energy to the backup power supply for energy storage; when the main power supply is insufficient, the power control module controls the backup power supply to supply power to the power board.
