JLT-08G intelligent terminal control cabinet is specially used for horizontal capacity regulating voltage regulating tap changer, and forms automatic capacity regulating voltage regulating power supply system with capacity regulating transformer. Stable the power supply voltage within the range required by the user, and adjust the operation of the transformer in low or high capacity according to the load to reduce the loss. The power supply voltage is not affected by the external voltage fluctuations and load changes, and then the power supply quality and the safety of electrical equipment are improved. The terminal has triple-phase voltage, current and power acquisition functions, can store 5000 event records, with wifi module, can realize mobile phone APP control. Moreover, it has RS485 interface, which can realize the wireless remote transmission of data after connecting with the distribution fusion terminal, and realize the intelligent application of the distribution platform area.
