Description

TECHNICAL FIELD

[0001] The application relates to the field of electronic information technology, in particular to a deep-fusion pole-mounted circuit breaker capacitor power supply device. BACKGROUND

[0002] With the increase of national energy saving and environmental protection efforts and the implementation of supporting policies, a large number of distributed power supply is connected to the power distribution network on the energy supply side, which poses a severe challenge to the safety, management and scheduling of the power distribution network. The deep-fusion pole-mounted circuit breaker capacitor power supply device, as a switching and off-grid power supply device, is self-evident in importance. Since the power of the deep-fusion pole-mounted circuit breaker capacitor is low, it cannot meet the switching on-off high-power power supply requirements, so the stability and service life of the backup capacitor are particularly important. The traditional power supply device can only charge the lithium battery. Once the lithium battery reaches the end of its service life, the deep-fusion pole-mounted circuit breaker will not be able to switch on and off, which poses a safety hazard to the power line. Therefore, we have developed a deep-fusion pole-mounted circuit breaker capacitor power supply device. The device can not only charge the lithium battery, but also has a built-in super capacitor module, which can solve the problem of short service life of single backup.

[0003] The traditional capacitor power supply device has only a single input and cannot charge the super capacitor. Once the backup lithium battery fails, the energy obtained by the input source capacitor cannot meet the instantaneous high-power output energy of the switching on-off, and the power supply time after power failure is short. At the same time, it does not have an electric quantity display, and it is not convenient to grasp the battery capacity. SUMMARY

The electric quantity in the device can be directly monitored by electric quantity display board 19.

[0043] The principle is as follows:

[0044] In combination Figure 1 , Figure 7 , the management unit is provided with CPU of model stm32f103VCT6. When CPU pin YK BL outputs high level, triode V2 is turned on, V1 MOST is turned on, VDD5 obtains +5V voltage, so that K1~K7 relays are all turned on, after the relay is turned on, B1- and B2+ of K1 are connected in series, B2- and B3+ are connected in series, B3- and B4+ are connected in series, B4- and B5+ are connected in series, B5- and B6+ are connected in series, B6- and B7+ are connected in series, after the series connection, 8 batteries are connected, the head end is B1+, the tail end is B8-, the voltage between B1+ and B8- is: 3.2*8=25.6V, which meets the voltage required when operating the closing and opening; at the same time, when CPU pin YK_DCTC outputs high level, relay K9 is turned on, VBL+ and VBL- are temporarily disconnected and connected with B1+ and B8-, which is powered by backup capacitor; at the same time, when CPU pin YK_KC outputs high level, relay K8 is turned on, BI+ and B8- are switched to DC24V_OUT- and DC24V_OUT+ through the relay, DC24V_OUT- and DC24V_OUT+ are the operating voltage when the controller operates the closing and opening.

[0045] When the closing and opening operation is completed, the CPU pin YK_DCTC outputs low level, the relay K9 is turned off, VBL+ and VBL- and B1+, B8- are connected, and the system voltage is restored to B1+, B8- power supply. At the same time, the CPU pin YK BL outputs low level, the triode V2 is turned off, the V1 MOST is turned off, so that the K1-K7 relays are all turned off to restore the default state, B1+ and B2+ of K1 are connected in parallel, B2+ and B3+ are connected in parallel, B3+ and B4+ are connected in parallel, B4+ and B5+ are connected in parallel, B5+ and B6+ are connected in parallel, B6+ and B7+ are connected in parallel, and the total capacity of the eight batteries after connection is 8*5Ah=40Ah, and the voltage remains unchanged at 3.2V. In the case of CPT1 and CPT2 external AC power loss, the rated voltage of the lithium battery is converted to the system power supply voltage 5V, and the efficiency is much higher than that of the traditional 25.6V direct step-down to 5V system power supply. Thus, through low-dropout voltage reduction, the power supply time of the equipment after power failure is improved. This power module skillfully uses the relay to switch the battery in series and parallel, reduces the loss and power consumption through low-dropout voltage, meets the high voltage amplitude required during the opening operation of the pole-mounted circuit breaker, and meets the working voltage during normal system operation.

[0046] The device management unit of the scheme has a power self-adaptive power CPT, which can simultaneously meet the external core unit output power, battery charging power and super-capacitor charging power, meet the power module output power = core unit power + battery charging power + super-capacitor charging power, and preferentially provide the core unit. When the core unit power exceeds the output power limit of the power module, the excess part is provided by the battery or the super-capacitor, such as the closing and opening operation and the energy storage stage, the 5G module communication stage. Once the battery overcurrent or short circuit protection occurs, the battery will be disconnected, and the battery needs to be restored through the battery start button. When there is CPT power supply, the battery will automatically recover. At the same time, the double CPT capacitor input solves the defects of traditional single input, and the working mode of lithium battery and super-capacitor double backup can solve the problem of short service life of single backup. At the same time, the voltage and current can be accurately monitored to avoid problems such as overcharge, overdischarge, current overcurrent damage and improve the service life of the battery.

Any skilled person in the art can make any simple modification, equivalent change and modification to the above embodiment according to the technical essence of the present application without departing from the technical solution of the present application.
