The battery of the LED explosion-proof light is actually the emergency device of the explosion-proof light. The main function is that when a sudden power failure occurs, the emergency device of the LED explosion-proof light will start to ensure the normal power supply of the LED explosion-proof light.
The current LED explosion-proof lamp technology is very mature, but the emergency equipment of explosion-proof lamps is not perfect. Either the emergency device cuts corners due to vicious market competition, or the manufacturers and customers do not pay enough attention to the actual utility of the economic device. In fact, emergency is also very important for explosion-proof lights.
Among the LED explosion-proof lamp batteries, lead-acid batteries are the most widely used high-efficiency batteries at present, and they have the advantages of high efficiency and high energy. However, in the process of use, a short circuit will also be caused due to improper use or other different reasons, thus affecting the use of the entire battery and even seriously affecting the battery life. So once the battery is short-circuited, how should we repair it? The first step must be to identify the cause of the battery failure.
There are many reasons for the short circuit of lead-acid batteries, among which the more common reasons are as follows:
1. The charging current is too large;
2. The charging voltage of a single battery exceeds 2.4v;
3. There is a short circuit or partial discharge inside;
4. The temperature rise exceeds the standard;
5. Valve control failure.
In view of the above five reasons, our corresponding processing methods are as follows:
1. Reduce the charging current, reduce the charging voltage, and check whether the safety valve body is blocked.
2. Regularly charge and discharge.
3. The floating voltage and discharge voltage of lead-acid batteries in the UPS power system have been debugged to their rated values before leaving the factory, and the discharge current increases with the increase of the load. The load should be adjusted reasonably during use. , such as controlling the number of electronic equipment such as computers.
