Table 4 Charging Performance

The Explosion-proof Special Power Supply Device consists of a special lead-acid battery, a battery box, connecting wires and a mining explosion-proof male pin connector, which can be used with the Explosion-proof Special Battery Electrical Locomotive in coal mines full with methane or coal dust explosion hazard.

1. The product is an Exsl Mining Explosion-proof Special Model. The structure performance conforms to the requirements in MT/T334-2008, GB10978-89 and GB3836.1-2000, and is appraised by related explosion-proof inspection station authorized in China.

2. The product mainly consists of a glass fiber tubular anode plate, a paste negative plate, a micro rubber or plastic partition board, an ethylene-propylene copolymer plastic battery jar, a battery cover and sulfuric acid electrolyte. Body hot-melt sealing is adopted for the battery jar and battery cover.

3. When the unit cells are combined into a battery pack, a special wire is used for soldering connection to reduce the contact resistance and prevent the spark from being generated, ensuring the safety of the use and the good wire connection of the battery pack under special circumstances.

4. In order to avoid short circuit of the battery pack, the exposed position of the electrical conductor shall be covered with insulated plastic sheath.

5. Sealant is applied on the casting interface of the connecting wire, so as to prevent corrosion of sulfuric acid, and guarantee safe use.

6. The acid-resistant special working plug is adopted for the battery, and is subject to hydrophobic treatment, so as to guarantee good air permeability of the battery, and reduce water consumption of electrolyte.

1. It is applicable for roadway with gas and coal dust explosion hazard.

2. The elevation shall not exceed 1,200m.

3. The maximum ambient temperature shall be 40℃/140℉, and the minimum shall be -20℃/-4℉.

4. The monthly average maximum relative humidity of the wettest month shall be less than 95% (the monthly average minimum temperature of the same month shall not be higher than 25℃/77℉).

5. No gas or conductive dust in the air enabling to cause corrosion to metal or damage insulation.

6. The maximum acceleration of impacts in the longitudinal direction of the electrical locomotive shall be no more than 30m/s2.

7. The narrow-gauge track roadbed and the turnout laying quality shall conform to provisions in GBJ213 Article 328: Safety Rules for Coal Mine.
