Description

Technical Field

[0001] The utility model relates to the technical field of nuclear capacitor discharge, in particular to an intelligent online nuclear capacitor discharge device. Background Art

[0002] The operating power supply of the high-voltage distribution room has a backup function to ensure that it can still play a guarantee role in the case of loss of AC power when an accident (such as short circuit) occurs. It is generally powered by professional equipment of the DC panel. The backup function in the DC panel is mainly lead-acid batteries, which are composed of multiple batteries connected in series. The general voltage is DC110V or DC220V. Due to its importance, once the equipment is running, it generally does not stop working. When working, the battery is always in an online backup state. The charger floats the battery for a long time to ensure that the battery is in a full capacity state, but long-term floating charging is not conducive to the service life of the battery. Usually, the battery is discharged (we call it activation) after a period of time (3 months, 6 months or 1 year) to extend the life of the battery. While discharging, you can measure how much electricity the battery can still discharge to ensure that the battery has sufficient discharge capacity when the AC power is lost;

[0003] After searching, the patent application with the patent number CN201820597021.X discloses an intelligent battery online nuclear capacity discharge control device, including a centralized monitoring unit, a main controller unit, an inverter unit, an inverter unit and a battery; wherein the centralized monitoring unit exchanges data with the inverter unit, and the inverter unit is electrically connected to the positive pole of the battery; the centralized monitoring unit exchanges data with the main controller unit, the main controller unit exchanges data with the inverter unit, the inverter unit is connected to the negative pole of the battery, and the inverter unit is simultaneously connected to the AC power grid;

[0004] The above application document realizes the reasonable utilization of electricity through the setting of the inverter unit therein; the current online intelligent discharger device can discharge the battery electricity through the original load equipment, which can not only achieve the purpose of discharge activation and detection of battery capacity, but also does not make the battery out of the system to affect the reliability of the system, and does not generate additional heat. However, when the discharger is in use, in order to facilitate the transfer of the discharger, the lower end of the discharger is provided with multiple sets of rollers, and the discharger vibrates when working. At this time, the rollers are easy to move with the discharger, and the discharger is difficult to be stably distributed at the place of use. In addition, the existing discharger needs to disconnect the battery from the DC panel when working, which will cause a safety hazard (that is, the city power is suddenly cut off, and the battery is in a disconnected discharge activation state when switching to DC power supply, and cannot provide power to the high-voltage cabinet integrated protection device and energy storage mechanism in time). At least 2 people are required to operate on site to achieve the purpose of discharge activation.

[0005] Therefore, we proposed an intelligent online nuclear capacity discharge device. Utility Model Content

[0025] Among them, the intelligent online nuclear capacity discharge device can stably place the discharge instrument body 14 by setting the DC power supply equipment frame 1 outside the discharge instrument body 14, avoiding the discharge instrument body 14 from vibrating during discharge detection and causing the discharge instrument body to move, thereby achieving the effect of improving the stability of the discharge instrument body 14 during operation, and solving the problem of poor stability of the existing discharge instrument body 14 caused by working vibration.

[0026] Embodiment 2:

[0027] The DC power supply device frame 1 is provided with a load circuit and a boost circuit therein, and the load circuit and the boost circuit are electrically connected to the battery pack and the charger;

[0028] Among them, the intelligent online nuclear capacity discharge device uses the original load to discharge, does not generate heat, and saves energy. The charger and battery are always in hot standby mode, and seamlessly switch when a fault occurs to ensure safe use of electricity.

[0029] The working principle and use process of this utility model: Figure 3 As shown, in normal conditions, K1 is closed and does not affect the operation of the equipment. During discharge, K1 is disconnected, D1 is cut off, the charger is in hot standby state, and the boost device raises the battery voltage to make the voltage slightly higher than the charger output voltage, and discharges the battery power through normal loads to achieve the purpose of discharge. In case of fault, D1 is turned on and the output is uninterrupted;

[0030] Standby state: Relay K1 is closed, the system is in standby state, and the original equipment is exited; K1 adopts a normally closed point, so even if a fault occurs, it will not affect the operation of the original system, ensuring power supply safety;

[0031] Preparation before discharge: When receiving local or remote instructions, or when the timing cycle is reached, the device starts to prepare for discharge. First, it actively reads or monitors the DC screen data (which can be set through parameters) to ensure that the DC screen has no faults; secondly, it measures the battery voltage and current. The voltage must be higher than the set value, and the charging current must be less than the set value before discharging begins;

[0032] Discharge process: disconnect K1, close K2 according to the setting, and the discharge load works; the boost device starts to work, the boost device is in constant voltage and current limiting mode, and the voltage is set to be slightly higher than the charging voltage. When the normal load current is greater than the discharge current (the discharge current may be reduced by the discharge load current, depending on whether the discharge load is connected), the boost device is in current limiting mode, that is, the boost device dynamically adjusts the output so that the discharge current is exactly the set value. At this time, the output voltage of the boost device is consistent with the output voltage of the charger (because the charger will share part of the current). When the normal load current is less than the discharge current, the boost device dynamically adjusts the output so that the discharge voltage reaches the set value. At this time, the discharge current will be less than the set value;

[0033] The internal device of the online intelligent discharger records the time when discharge starts, then obtains the data of the DC panel in real time, measures the battery voltage and discharge current, and updates the discharge capacity every minute. The data (including battery voltage, battery current, and single cell voltage) are recorded every 10 minutes;

[0034] End of discharge: When the internal device of the online intelligent discharger cannot obtain the DC panel data, or the DC panel fails, or the total battery voltage is lower than the set value, or the single cell voltage is lower than the set value, or the set discharge time is reached, the discharge is terminated and the discharge results (reason for termination, termination time, voltage at the end, current, single cell voltage, discharge time, discharge capacity) are recorded, the boost device is turned off, K2 is disconnected, K1 is closed, and the device exits the original system. The last discharge result can be read at any time. The single chip microcomputer can store the latest 20 discharge records, which can be viewed through the touch screen.

[0035] Under normal circumstances, the load of the DC panel is powered by the charger at the same time, and the battery is also equivalent to a load of the charger. The online intelligent discharger device is equipped with a boost device. When discharging, the boost device raises the voltage to a level close to the charging voltage of the charger. Part of the load of the DC panel is powered by the battery to achieve the purpose of discharge without generating additional heat. A check diode is set between the battery and the load to ensure uninterrupted power supply to the load when switching between charging and discharging modes or when an accident occurs during the discharge process. When the online intelligent discharger device is used to activate the battery, the battery is always online to ensure the reliability of the system without generating additional heat, and it can be completely unattended.

[0036] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
