Mine power supplies are widely used. At present, most mining equipment uses lead-acid battery mine power supplies. When mine lead-acid batteries are used, they will produce hydrogen gas, which is an explosive gas. In the environment where the explosion risk rate is extremely high in mines Extremely unsafe; in addition, mining lead-acid batteries are large in size, small in capacity, heavy, and inconvenient to transport and place; and mining lead-acid batteries have short service life, low activity, and poor low-temperature performance, which greatly affect the use of mining lead-acid batteries The environment and conditions of use bring many uncertainties to the use of mining equipment, resulting in losses
In addition, due to the different power supply specifications required by mining equipment under different working conditions, the existing power supply methods are difficult to meet different power supply requirements

The invention discloses a mining electric locomotive power supply system, which comprises a plurality of groups of mining explosion-proof lithium ion storage battery power supply devices which are connected in series, in parallel or in series-parallel combination, and are connected to a total positive electrode end and a total negative electrode end of electric locomotive electric equipment to supply power to the electric locomotive electric equipment. Each group of mining explosion-proof lithium ion storage battery power supply devices is connected to an electric locomotive control system anda display system through a data bus and is used for controlling operation of each group of mining explosion-proof lithium ion storage battery power supply devices and displaying operation parameters.The mining electric locomotive power supply system does not generate harmful combustible gas in the use process, is safe and reliable to use, can realize various power supplies with different specifications through different series-parallel connection combination modes of the mining explosion-proof lithium ion storage battery power supply device, and meets different power supply requirements.
Description
technical field [0001] The invention relates to a mine power supply, in particular to a mine electric locomotive power supply system that can replace the lead-acid battery power supply for mine rail electric locomotives. Background technique [0002] At present, with the improvement of coal mining technology level, my country's large mining height fully mechanized caving face has developed rapidly. Mine power supplies are widely used. At present, most mining equipment uses lead-acid battery mine power supplies. When mine lead-acid batteries are used, they will produce hydrogen gas, which is an explosive gas. In the environment where the explosion risk rate is extremely high in mines Extremely unsafe; in addition, mining lead-acid batteries are large in size, small in capacity, heavy, and inconvenient to transport and place; and mining lead-acid batteries have short service life, low activity, and poor low-temperature performance, which greatly affect the use of mining lead-a...
