Description
Technical field
The present invention relates to operating power electric power system technical field, be specially a kind of electric power operation power supply based on ultracapacitor energy storage.
Background technology
At present, the power supply reference power supply of operation control box in traditional high voltage permanent vacuum switch cabinet and ring main unit, when external PT input AC electricity is effective, by a unidirectional AC-DC module in road, by the 220/110V AC rectification of input, be all 24V direct current, as the input reference voltage of controller and actuator.Meanwhile, in operation control box, all have 12V/24V maintenance-free battery as energy-accumulating medium, and can be by the unidirectional AC-DC module in another road to energy-storage battery constant current charge.When the inefficacy of 220/110V alternating current being detected, energy-storage battery is exported 24V direct current by Uniderectional DC-DC module immediately, thereby has solved switch cubicle and the operating power powerup issue of ring main unit under circuit power down mode, and such scheme is referred to as scheme one.Also have a kind of power supply plan, be referred to as scheme two here, compare scheme one, maximum difference is that energy-storage battery passes through bi-directional DC-DC module and is connected with output direct current 24V port.When input 220/110V alternating current is effective, by the unidirectional AC-DC module output in a road 24V direct current, pass through bi-directional DC-DC module to energy-storage battery constant current charge simultaneously; When the inefficacy of 220/110V alternating current being detected, energy-storage battery is immediately by bi-directional DC-DC module output 24V direct current.This scheme can solve switch cubicle and the ring main unit operating power powerup issue under circuit power down mode equally.
Although above-mentioned two kinds of power supply plans design all can realize the uninterrupted power supply ability of operating power, but still there is following technical problem: 1, in scheme one, while adopting unidirectional AC-DC module to energy-storage battery constant current charge, pressure reduction between its input ac voltage and energy-storage battery end of charge voltage is larger, conventionally 15-20 times of left and right, cause charging circuit structural design relative complex, reliability reduces; 2, in scheme two, adopt after bi-directional DC-DC module, pressure reduction between energy-storage battery end of charge voltage and output direct current 24V is less, and use an AC-DC constant current charge module than scheme one is few, but there is the switching of constant current charge and two kinds of mode of operations of chopper control in bi-directional DC-DC module, make control circuit design relative complex, stability and reliability decrease.In addition, when input 220/110V alternating current is effective, by the unidirectional AC-DC module output galvanic while of 24V, also pass through bi-directional DC-DC module to energy-storage battery constant current charge, can cause like this design power of unidirectional AC-DC module larger, reduce operating efficiency.3, two schemes all needs to input the state of 220/110V alternating current or the state of output direct current 24V judges whether input AC power supply lost efficacy by detection, and to determine whether start energy-storage battery power supply, thereby real-time is poor.Once and detect inefficacy and can cause power failure, also make reliability reduce.4, two schemes adopts maintenance-free battery as energy-accumulating medium, and its useful life is low and need often replacing, and actual maintenance cost and workload are increased.
