　　button battery 2025 isolation discharge test, UPS battery discharge process

　　button battery 2025 isolation discharge test, UPS battery discharge process. The button battery 2025 offline charge and discharge test system includes a UPS power supply, a battery pack to be tested electrically connected to the UPS power supply, and a debugging device connected to the UPS power supply. In battery testing, the discharge method is a commonly used method. . The test interval is generally once a year to verify the capacity of the button battery 2025.

　　button battery 2025 isolation discharge test method

　　1. First, check the button battery 2025 body and the switch instrument data on the power side and load side. If there is no abnormality, proceed to the next step;

　　2. Place the dummy load in a well-ventilated and safe location in the corridor, and connect the backup cable to the dummy load (a DC 4P400A circuit breaker is set in the middle of the wiring cable, and the switch is in the off position) for backup;

　　3. Connect the dummy load control power supply to the backup switch of the corresponding voltage level for backup;

　　4. Confirm with the monitoring personnel through intercom, turn off the button battery 2025 switch, and prepare for wiring; the battery pack side is wired according to the planned wiring method and voltage level. The wiring personnel should wear insulating gloves and use insulating tools to remove the copper connecting bars of No. 96 and No. 97 batteries in the battery pack, and connect the cable (120mm) connected to the dummy load phase line firmly to the positive terminal of the button battery 2025 and to the dummy load neutral line. Connect the temporary wire to the negative terminal of the battery pack for later use.

　　5. Turn on the UPS battery group monitoring equipment and start monitoring the data of each battery to be tested;

　　6. Power on the dummy load control loop and turn on the dummy load; close the switch in the middle of the temporary battery test line and use a multimeter to test whether the voltage at both ends of the switch is consistent with the battery pack voltage (-216V);

　　7. Turn on the false load test mode: select the load switch test with the corresponding power level (a smaller power should be selected at the beginning), and use a clamp ammeter to detect the test current carried by the cable in real time (overload testing is not allowed).

　　8. Through the test, observe the voltage drop of each battery in the button battery 2025 to see if any individual battery has a large voltage drop. Also check the appearance of each battery. The test current should not exceed the battery pack C10 discharge current. The test time should be combined with the on-site battery pack voltage drop. The single cell voltage should not be less than 1.85V.

　　9. After the test, restore the button battery 2025 wiring and switch status.

　　UPS battery discharge process

　　1. Set or calculate the UPS battery discharge time: Calculate the standby time based on the LCD panel display time or the number of batteries, and set the power outage time to 30% or 25% of the calculated time.

　　2. Directly turn off the "rectifier input switch" of the UPS and observe that the UPS LCD panel displays the remaining time and battery voltage, or that the number of indicator lights on the UPS front panel is not less than half of the original number of lights.

　　3. When the UPS battery is discharged to the battery low voltage alarm value, or the time reaches the previously budgeted time, close the "rectifier input switch" of the UPS.

　　Summary: The above is the isolation and discharge test of the button battery 2025, the UPS battery discharge process, grasp the operation status of the UPS equipment in the station, troubleshooting, bottom-up, charge and discharge test of the battery pack, identify damaged and failed single-bottle batteries, and restore the overall performance of the battery pack , it is very necessary to ensure that the UPS system is working properly.
