Accompanying drawing explanation
Accompanying drawing 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing, the utility model is introduced.
Fig. 1 is the intelligent low-pressure distribution JP compensating cabinet of the utility model based on GPRS, comprise JP compensating cabinet power supply unit, Intelligent capacitor unit, GPRS communication unit, Intelligent capacitor unit is by intelligent operation/cutting controller, lead-in circuit breaker, combination switch, secondary capacitor forms, JP compensating cabinet power supply unit is connected with the intelligent operation/cutting controller in Intelligent capacitor unit, this intelligent operation/cutting controller is connected with GPRS communication unit by RS485 interface, intelligent operation/cutting controller adopts high-performance, STM 32F100C6T6B type 32 ARM CORTEX-M3 core microprocessors of high integration are as master controller, the inner integrated analog-to-digital conversion collector of this controller, the voltage of Real-time Collection power supply unit, the parameter such as electric current and frequency, by calculating the demand of electrical network reactive power, again according to built-in Optimal Control Strategy, control the switching to secondary capacitor, realize the reactive power compensation to electrical network, the two-way of this controller configuration simultaneously Universal Asynchronous Receive/dispensing device (universal asynchronous receiver/transmitter, UART) serial communication port, wherein a road converts RS485 communication to, by being connected with GPRS communication unit with RS485 interface, another road serial ports convert to communicate when RS232 is multiple stage low-voltage intelligent capacitor parallel operation special.
It is 4 toggle switchs that the mailing address of secondary capacitor arranges structure, on off state is gathered by microprocessor I/O mouth, arrange from 0000-1111 totally 16 different addresses, definition address is set to the Intelligent capacitor of 0000 is in software isolated operation state, address be 1111 Intelligent capacitor be state out of service, remaining address is group net operation state, therefore, maximumly can allow 14 low-voltage intelligent capacitor parallel runnings, meet the requirement of current most JP compensating cabinet capacitance compensation branch road, the setting of mailing address is completed by toggle switch, easy to operate, substantially increase operating efficiency when JP compensating cabinet batch is installed.
