The power distribution method and the switch cabinet provided by the invention have the advantages that the electrical modules can be intelligently matched, and the power distribution limitation without power interruption and the auxiliary detection of aging damage can be realized.
The invention achieves the aim through the following detailed technical scheme:
an intelligent power distribution method for an inflatable cabinet comprises an electrical module pairing stage and a conventional power distribution stage, wherein in the electrical module pairing stage, a plurality of electrical modules are sequentially arranged on an insulating fixing frame side by side through clamping frames, each electrical module is directly in communication connection with a controller of the inflatable cabinet, and each clamping frame is sequentially in series communication connection and then is in communication connection with the controller of the inflatable cabinet; the method comprises the following steps that an electric module sends a pairing request to a controller independently, a clamping frame measures the width of the electric module and then directly or indirectly sends width data to the controller, the controller establishes a simulation installation diagram according to preset data and the width data of the electric module, the electric module is positioned and numbered through the simulation installation diagram, pairing is completed, a conventional power distribution stage is started, and power distribution is carried out according to the number of the electric module;
the conventional power distribution phase comprises the following actions:
action A1: the controller controls each electrical module to distribute the actually required electric quantity of the electrical equipment connected with the electrical module when the total actual load electric quantity of all the electrical equipment connected with the gas-filled cabinet is lower than the rated power distribution load of the gas-filled cabinet (namely the distributable maximum load electric quantity of the gas-filled cabinet); meanwhile, the electric module detects the input current, voltage, output current and voltage of the electric module through the sensor, the detected data is generated into a data packet and sent to the controller, each electric device has specific rated voltage and current, and the electric module requests the distributed electric quantity to be the rated electric quantity required by the electric device in the initial use, namely the specific voltage and current;
action A2: data analysis, namely after the controller receives a data packet sent by the electrical module, storing the data and generating a database of the electrical module, comparing whether the actual input voltage is equal to the rated voltage of the electrical module or not, and comparing whether the input current is greater than the rated current of the electrical module or not; respectively establishing a coordinate system for the output current and the output voltage, recording the maximum value, the minimum value and the average value of a change interval, simultaneously calculating a regression curve function of the average value changing along with time, wherein the electric equipment can generate current or voltage fluctuation within a certain range according to the power change during the operation, in particular to the electric equipment with adjustable power, the average current and voltage output value of an electric module is the most common power or the power closest to the common power of the electric equipment, the average value in the average value with a more gentle curve section is selected from the regression curve function to be used as the average value of subsequent actions (such as the average output current in actions A3 and A4) for distribution limitation, the power of the electric equipment can be more accurately limited to be close to the most common power, and the sudden change of the current or voltage average value can be more intuitively seen through the regression function curve of the average value, the monitoring is convenient;
action A3: one-level distribution limitation, when the total actual load electric quantity of all electrical equipment connected with the gas-filled cabinet is greater than the rated distribution load of the gas-filled cabinet, the controller compares the actual output current and the average output current of each electrical module, calculates the difference between the actual output current and the average output current of the electrical modules, and controls the electrical modules from the minimum difference to the maximum difference to start to perform distribution limitation in sequence, wherein the distribution limitation mode is as follows: the actual output current is reduced to the average output current while keeping the input voltage unchanged until the total actual load electric quantity is equal to or less than the rated distribution load of the gas-filled cabinet, when the distribution load of the switch cabinet is greater than the rated load of the switch cabinet, the damage of the switch cabinet is possibly caused, the service life and the operation of the switch cabinet are influenced, and even potential safety hazards are caused, so the distribution of each electrical module needs to be limited, the traditional method can close the electrical equipment with lower distribution priority level to reduce the distribution load, but the sudden power failure ensures the overall safety, but influences the use of the electrical equipment which is powered off and also influences the use experience of users, while the primary distribution limitation in the invention only reduces the distribution current to the average current, namely reduces the power of the electrical equipment, the electrical equipment can still operate, and not only ensures the operation of all the electrical equipment, the total load can be reduced, the safety and the user experience are ensured, meanwhile, the limitation is carried out from the electrical appliance with the minimum difference value with the average current, the influence is not great even if the power is reduced due to the small difference value, the excellent user experience is ensured as much as possible, and the influence of the power distribution limitation is reduced to the minimum;
