technical field

According to my country's guiding policy on electricity prices, the electricity price is the highest during the peak and valley periods of electricity consumption, followed by the flat valley periods, and the lowest during the low valley periods. Even under the effect of such price leverage adjustment, there is still the status quo of "shortage of electricity during peak and valley periods of electricity consumption, and power cuts are imposed on users; while excess electricity during off-peak periods forces generators to stop operating". Saving it for use during flat valley and peak valley can not only save energy, but also bring considerable economic benefits to users.

Once the power consumption of the electrical equipment is too large or the energy-saving device fails, the production operation cannot be continued and the work is forced to stop. It is easy to cause economic losses to users.

The power detection device 7 is connected to the battery 3; the first parallel circuit 6 is also provided with a first control element 9, and the first control element 9 is connected in series with the main switch 8 of the electrical equipment; wherein, the battery The input voltage of 3 is AC 220V, and the output voltage is DC 12V; the input voltage of the inverter 4 is DC 12V, and the output voltage is AC 220V; further, it also includes a second parallel circuit 10, and the second parallel circuit One end of the circuit 10 is communicated with the electrical equipment 5, and the other end of the second parallel circuit 10 is communicated with the mains; the second parallel circuit 10 is provided with a second control element 11, and the second control element 11 is connected with the utility power. The main switch 8 of the electrical equipment is connected in series; a third control element 12 is arranged between the battery 3 and the inverter 4, and a fourth control element 13 is arranged between the inverter 4 and the electrical equipment 5; wherein, the A fifth control element 14 and a sixth control element 15 are provided between the timer 1 and the charger 2, the fifth control element 14 is connected in series with the sixth control element 15, and the power detection device 7 is provided with the fifth The upper limit power cut-off control module 16 connected to the control element 14; furthermore, the timer 1 is provided with a seventh control element 17, and the seventh control element 17 is connected with the sixth control element 15, the first control element 9, The third control element 12 and the fourth control element 13 are connected in linkage; furthermore, the power detection device 7 is provided with a lower limit power cutoff control module 18, and the lower limit power cutoff control module 18 is connected to the second control element 11 ; Wherein, the second parallel circuit 10 is connected with the commercial power and the electric equipment 5 to form an independent power circuit.

In the present invention, the timer 1, the charger 2, the storage battery 3 and the inverter 4 form a storage battery circuit. The present invention adds a first parallel circuit 6 and a power detection device 7 to the storage battery circuit in the prior art, The power detection device 7 can detect the power of the storage battery 3. Since the power detection device 7 is provided with an upper limit power cut-off control module 16, when the battery 3 is full, the power detection device 7 can control the timer 1 and The charger 2 is disconnected to stop charging the battery 3 to prevent damage to the battery 3 due to overcharging; because the electrical equipment 5 cannot receive power from the battery 3 through the inverter 4 during charging, the user has no power during this period. Available, at this time, the first parallel circuit 6 can be connected to the mains to directly supply power to the electrical equipment 5; or when the battery 3 is powered by the battery 3 during the flat and peak periods of the day, the battery circuit fails or bursts There is a lot of power consumption, and at this time the power of the storage battery 3 is low.

In the preferred embodiment of the present invention, the above-mentioned control elements all use AC contactors.

The working principle of the present invention is as follows:

First, it is set by timer 1. When the time period is in the low power consumption period, first, the seventh control element 17 set by timer 1 and the sixth control element 15 of the battery circuit are connected to the mains to charge the battery 3. When the third control element 12 and the fourth control element 13 are disconnected, the electricity in the low-valley period is stored. The fifth control element 14 is disconnected, thereby stopping charging the storage battery 3; secondly, when the storage battery circuit is charging, the first control element 9 is closed at this time, and the main switch 8 of the electrical equipment connected to the first parallel circuit 6 will be at The lowest-priced commercial power during the off-peak period is directly supplied to the electrical equipment 5 for use, and the user can also use electricity normally during the charging period of the storage battery 3 . During the whole day's power consumption valley period and power consumption peak valley period, the DC power of the storage battery 3 is converted into AC power by the inverter 4 for use by the electric device 5 . When all-day flat and valley periods and peak and valley periods are powered by the battery 3, the battery circuit breaks down or consumes a lot of electricity suddenly, and when the battery 3 is low, in order to protect the battery 3 and allow the electrical equipment 5 to continue to power, you can By closing the second control element 11 and connecting the second parallel circuit 10 to directly connect to the commercial power to supply power to the electrical equipment 5, normal production or work is not affected and losses are avoided. Of course, users can purchase batteries 3 with different capacities according to their own electricity requirements, so as to meet the electricity requirements of different electrical equipment 5 . If electricity is not needed during the off-peak period, the main switch 8 of the electrical equipment can be disconnected, and there is no need to supply power to the electrical equipment 5; if the enterprise implements a day and night shift work system (including the off-peak period) or the family uses electricity all day During the off-peak period, the main switch 8 of the electrical equipment can also be connected to directly supply the mains power to the electrical equipment 5. Since the electricity price in the off-peak period is the lowest at this time, the cost of electricity consumption can be effectively reduced.

The timer 1, the charger 2, the storage battery 3, the inverter 4 and the power detection device 7 described in the present invention can all be directly purchased in the market, and have a simple structure and low cost. And the present invention can not only make the electrical equipment 5 uninterrupted power supply 24 hours a day, but also can make good use of the discount of off-peak electricity consumption. During off-peak hours, the electrical equipment can directly use the lowest priced electricity, or charge the storage battery 3 with the lowest priced electricity, so that the storage battery 3 can supply power to the electrical equipment 5 during the flat and peak periods of the day, effectively reducing the cost of electricity consumption , and bring considerable economic benefits; at the same time, it also contributes to power plants, power grid safety, environmental protection and energy conservation, and effectively solves the current problems of limited energy reserves and failure of energy-saving devices that cannot continue production.
