China is a big energy country. There are many mines in some areas in northern my country. Because of the remoteness, long power supply and transmission lines, the location of underground operators, the need to monitor gas and air supply, etc., the mines must be equipped with emergency backup generators. Some special areas need to use engine generator sets for long-term main power genset due to the inaccessibility of the main line. Therefore, mine dg sets have higher power requirements than conventional places. So we need to pay attention when purchasing mine dg genset. What are the problems?
Knowing the electrical equipment of your own mine is the first step. What you need to know is the type of electrical equipment and the power of the main motor, starting method, starting law and other factors. What needs to be specifically explained here is that the equipment of the mine is generally a single motor. The power of the generator is very large, so it is necessary to choose a more excellent starting method, otherwise the investment budget for choosing a dg set will be doubled.
On the other hand, large motors 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 resources and financial resources. At present, the starting methods of motors are roughly as follows: direct start/Y-△ step-down start/self-coupling step-down start/soft start/frequency conversion start, etc. Most mines use large-capacity motors, the first two are basically impossible, so You can make comprehensive choices in the latter three based on your own investment budget, communicate with equipment manufacturers and generator sets manufacturers, and select the best and appropriate plan. After selecting the starting mode, calculate the starting current (during the worst working condition) and running current of all equipment, and finally calculate how much power genset needs to be configured.
In mines, everyone knows that the use environment is very harsh, and even some places are in high altitude areas. The power carrying capacity of dg set is the same as human beings. The power carrying capacity decreases with the increase in altitude, so special attention must be paid to this factor. Take it into consideration, otherwise it will cause the disadvantages of the purchased power and the actual operating power.
Manufacturers of engine generator sets specializing in mines will have some special configurations, such as heavy-duty filters for wind and sand prevention, low-temperature starting devices, early warning devices for regular maintenance of the units, and advanced crankcase pressure alarm devices. The device is undoubtedly the greatest protector of the generator set. Most of the mine’s dg genset are operated in parallel. The signs of major faults in the dg set cannot be observed with sound or naked eyes (such as abnormal noise, jitter, minor three leaks, etc.). The alarm device can effectively monitor the crankcase pressure, and can greatly avoid the occurrence of some major engine failures (such as the fatal cylinder pull and pull phenomenon for the generator set).
Most of the mine's generator sets are far away from the main urban area, so the technical level of the generator set operators must be high. The improvement of this type of technology can be achieved through cooperation with some manufacturers with large-scale training and technical support. The unit is an important means of production for the mine, and it is natural to call it the "pioneer army". Therefore, it is particularly important to deploy high-level technicians!
For the mine generator set used by the main force, it is necessary to reserve one more set for long-term backup. This seems to have a large investment in the short term, but as long as it is equipment, when there will eventually be a failure, then one more standby dg set must be very necessary in the long run!
If you buy 344 kVA dg set for mine industry standby and prime power application, you could check the following specification.

The last point is that the mine dg set needs to routinely purchase and inventory the daily wearing parts and easy-to-fault parts, so that spare parts can be provided for emergency standby power when a failure occurs.
There are many types of generator sets, and there are different types of generator sets according to different standards. 1. Divided by power source: diesel generator sets, gas generator sets, gasoline generator sets, wind generator sets, solar generator sets, hydroelectric generator sets, coal-fired generator sets, etc. 2. Electric energy mode: According to the converted electric energy mode, i...more
