What are the contents of the inspection of the battery inspection? What safety matters should be paid attention to in maintaining lead-acid batteries?
1. The inspection items for the battery are:
1, the DC bus voltage should be normal, should not exceed 2% of the average voltage, the floating charge should be appropriate, no charging or undervolving.
2, measure various parameters. When the power is floating, the battery voltage should remain at 2.1 to 2.2V, and the charge and discharge voltage shall not be less than 1.8 to 1.9V. The relative density of the electrolyte should be between 1.215 to 1.229, and the liquid temperature should be maintained between 15 to 35 ¡ã C.
3, check whether the polar color is normal, there is no tilt, bending, short circuit, salt and effective substance falling off.
4, wood blockboard, lead card should be complete, no point off.
5, the liquid surface should be higher than the polar plate 10 to 20 mm.
6, the shell of the battery should be complete, no inclined, and the surface should be cleaned.
7, each joint connection should be fastened, no corruption, and coated with Vaseline.
8. Ventilation equipment and other subsidiary equipment should be intact, there is no intense smell in the indoor, and the battery room temperature should be between 10 and 30 ¡ã C.
9, the floating charge equipment is operating normally.
10, DC system is insulated.
11. The alkaline battery should also be checked whether the bottle cap is screwed, and the air hole should be smooth.
