On the power supply unit to promote the feasibility of an integrated substation


Disappear, it can seamlessly switch to battery power, automatically by the blocking diode, inverter, static switch to the UPS load. Integrated power supply block diagram shown in Figure 2. Maintenance bypass power supply connected battery integrated power supply block diagram of Figure 2 DC power supplies can not be applied to any fault affecting the DC bus, the bus can cause grounding and other abnormalities. Therefore, one should pay attention to noise, input and output frequency are required for isolation transformer, the second is the exchange side of the feeder switch to strictly meet the selection differential with the principle. 2. Note that the choice of battery capacity, enough to consider the exchange of load capacity to ensure uninterrupted power supply capacity and the exchange discharge time is guaranteed. Note that the load classification of switching operation and management 4. Dedicated power. DC input from the DC operating power management have a significant effect only really necessary to provide uninterrupted power supply to provide feedback of the battery, and AC input and DC input and AC transmission lines, feeder is not appropriate,ed hardy paris, and should adopt the radial power supply. The pressure between the insulation and electrical systems to meet such requirements. 3. Need to set the UPS maintenance bypass switch to ensure maintenance and more 5. Cost savings and operating costs. If a station by three dollars for the system during the normal power supply, and any running computer to be equipped with UPS power calculation, each station requires an investment of 9000 first wife under the operation and maintenance switches can not be damaged equipment. Qi can work 0.5h of the UPS, and need to be replaced once every three years. 4. Disk on an integrated power supply and integration of analog signal should have ordered the DC power supply is taken into account enclosure features a good exchange, in addition to indicating devices running conditions, it should also refer to the UPS configuration with an increase of 2 million can be solved about 10 years guided the operator function. By the operator to ensure the exchange does not mimic the signal off the power to ask the configuration, is economical and safe. The instructions, misuse does not occur. Using the integrated power supply unit should pay attention to several issues: integrated power supply systems rely on stations with high-reliability DC-1. As the dedicated AC power supply systems do not ask straight off of an effective solution to the ongoing problem of spare AC DC, stream input from the DC power system operation, and DC operating power to facilitate the maintenance of lower operating costs to provide a viable method, system is not grounded in a system, should ensure the exchange side of the new, renovation and expansion project has a good run prospects. ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ ※ (on the pick 73) 3. Lightning protection module is normally provided by varistors, gas discharge tube, air switch, discharge instructions and so on. Recommended to periodically perform an inspection of lightning protection. Especially the thunderstorm-prone season. Lightning indicate generally small, light-emitting faint and difficult to find in the usual operation of attention should be paid. There are observation windows for lightning protection module, you should always check whether the observation window color from green to red when the colors are all red viewing window must be replaced when the lightning protection module. There are three indicators for the lightning protection module, when any one is off, power should be replaced. 4. They often have to check mine air switch should be placed in actual operation the closed position. 8 Conclusion The emergence of integrated supply is the rapid development of power system the inevitable outcome. On the rational allocation of power resources play a good role. Improve the economics of grid construction, the power grid more secure and reliable. Saving maintenance for the unmanned substation basis. I consider the use of uninterrupted power supply to the DC as the main power supply for operating the first stage, the other electrically operated power supply as the load, as a second-class way better. Since it is decentralized power in their own way on the basis of developments,sac hermes birkin, some fragmented decentralized power more difficult to find ground faults while the inherent defects, sometimes not completely solved. Need to continue efforts to improve. Integrated design throughout the system, but also to meet the needs of mutual isolation. In battery maintenance, not only to consider the battery cell voltage monitoring line (currently most of the product only this one),abercrombie fitch paris, should also consider the single-capacity battery line monitoring. FDQ-2 Intelligent Battery Capacity Tester can do this. Work to strengthen the operation of the mine work in the inspection and timely replacement of the damaged lightning protection module. With remote monitoring of power, the power network should be used to achieve the central station on duty checking system for the regular run of the power to inspect and online monitoring. As long as we continue to find problems in the operation,christian louboutin pas cher, to strengthen cooperation with the manufacturers, research and solve problems, the power level of technology integration will be a higher level, will be more widely used. 4I 2007 ah / 68
