Due to its remoteness, long power supply and transmission lines, the location of underground workers, the need for monitoring of gas and gas supply, and other factors, it is necessary to set up a backup diesel generator set. In some special areas, the diesel generator set is required for the reason that the main line cannot be reached. Long-term main power generation, so the diesel generator set of the mine is an important means of production of the mine, and it is taken for granted that it is a "vanguard".
First of all, the operating environment of mine diesel generators is very harsh, and even some places are at high altitudes. Diesel generators are like human beings. The power carrying capacity decreases with the increase of altitude, so special attention must be paid to Take this factor into consideration, otherwise it will lead to the disadvantage that the purchased power is inconsistent with the actual operating power. Secondly, the commonly used power of mining diesel generator sets is relatively large, and some require 660V or higher voltage. The diesel generator set must use the common power, and cannot select the backup power diesel generator, otherwise it may not reach the power required for the start of its own equipment, resulting in losses. On the other hand, the large diesel generator sets used in mines have a common feature, that is, the problem of large starting load but small load after operation.
If the calculation is not good or the starting method selected is not good, it will waste a lot of manpower, material and financial costs. . Thirdly, due to the particularity of the location of the diesel generator set, the mining diesel generator set should often replace its air filter, oil filter and diesel filter to ensure the output power of the generator set, so the maintenance of the unit should be convenient, and the average failure interval of the unit The period is long.
