Solution To Short Circuit Of Battery In Mine Battery Locomotive

The following is mainly about the analysis of short circuit of lead-acid batteries caused by excessive charging current, single battery charging voltage exceeding 2.4V, internal short circuit or partial discharge, excessive temperature rise, valve-controlled failure, and summarizes the following treatment methods for short circuit of lead-acid batteries.

The first step is to reduce the charging voltage, reduce the charging current and check whether the safety valve is blocked. Discharge and charge regularly. The floating charge voltage and discharge voltage of lead-acid batteries have been adjusted to the rated value when they are out of the factory. The discharge current increases with the increase of the load, so the load should be adjusted reasonably in use.

Normally, the load should not exceed 60% of the rated load of battery electric locomotive. Within this range, there will be no excessive discharge of battery. Lead-acid batteries will lose part of their capacity due to self-discharge. Therefore, before they are put into use after installation, the remaining capacity of lead-acid batteries should be judged according to the open-circuit voltage of batteries, and then the batteries should be recharged by different methods. For standby batteries, the open circuit voltage of Panasonic batteries can be measured to determine the battery's quality.

Therefore, in the process of using lead-acid batteries, we must pay attention to the correct use of batteries, absolutely not short circuit. When installing lead-acid batteries, the wiring specifications should be well insulated to prevent overlapping pressure from rupturing. Insulation measures should be taken for the tools to be used. When connecting the batteries, electrical appliances other than batteries should be connected. After checking, there is no short circuit, and finally the batteries should be connected. Through these meticulous work, we can better prevent short circuit of lead-acid batteries, make lead-acid batteries safer to use and longer life.

Battery electric locomotives always use lead-acid batteries, but at present lead-acid batteries cause serious environmental pollution, and lead-acid batteries are difficult to use and maintain. Lithium batteries have been difficult to popularize because of their high cost. But Yutong traction electric research and development of a new generation of lithium-ion battery electric locomotive has perfectly solved these problems, will replace the traditional lead-acid battery electric locomotive.
