Battery charge and discharge testers are widely used in electric power, telecommunications, railways, manufacturing and other industries. In the previous sections, Guodian Zhongxing has successively introduced the product knowledge of battery charge and discharge testers. In this section, Win Thread Electric will tell you about the precautions and emergency measures in the use of the battery charge and discharge tester.
1. Precautions during installation
1. The ground wire must be connected to ensure equipment and personal safety.
2. Make sure that the "air switch" is in the off state to connect and disconnect the connecting wire from the battery pack.
3. The red connection wire of the battery pack is connected to the positive pole, and the black one is connected to the negative pole.
4. After the quick plug and charging power plug are inserted into the socket, they should be tightened clockwise to prevent heat generation during high current;
2. Precautions when setting parameters of battery charge and discharge tester
1. Charge/discharge current: take 1A as the basic unit;
2. The charging/discharging time should not exceed 59 minutes.
For example: 1 hour and 20 minutes, can not be set to 00HH80MM but 01H20M;
3. The low limit protection voltage of the battery pack: generally take 90% of the sum of the nominal voltage value of the battery. Set it correctly to prevent damage to the battery due to overdischarge.
4. Charge/discharge capacity: If the charge/discharge termination condition is not set according to the capacity, please set it to 9999Ah.
5. The voltage and current correction values before discharge are set to +00% or -00%
3. Precautions during the charging/discharging process
1. There must be someone on duty when the machine is working.
2. Do not touch the stainless steel cover with your hands during the discharge process to avoid burns.
3. In case of special circumstances, the "power switch" and "air switch" should be turned off immediately.
4. After charging/discharging is completed, when transferring data, wait until the display prompts that the transfer is over, and then unplug the U disk.
Fourth, emergency measures
1. When the voltage of a single battery is less than or equal to 11V or the voltage of the whole group of batteries is less than or equal to 198V, stop discharging.
2. When the indicated voltage of the battery discharge meter drops to 200V, the monitoring of the battery discharge should be strengthened to ensure that the battery must not be pressed below 198V and overdischarge.
3. Strictly observe whether the fan of the discharge instrument rotates during the discharge process. If it does not rotate, stop the discharge immediately.
4. When the discharge detector is connected to the battery, the positive and negative shall not be reversed.
5. The equipment is prevented from running in a well-ventilated, dew-free and non-corrosive environment, and the ventilation holes must not be blocked to ensure good ventilation!
6. When the discharge instrument is working normally, the connecting wire shall not be live, otherwise it will cause damage to the connecting terminal and circuit.
7. Safety measures should be taken when discharging and testing the voltage of the battery.
8. During the charging and discharging process of the battery, switch operations should be minimized.
9. During the discharge process, the on-duty personnel should strengthen the monitoring of the DC high-frequency module (AC-DC input and output voltage), the DC screen control, and the voltage of the combined bus, and report and deal with it in a timely manner when any abnormality is found;
