High power AC load 2800KW/3000KW generator test load Marine unit/shore load

 With the advantages of long output distance and low loss, high-voltage generator sets not only play an important role in data centers, power stations, medical care, finance, insurance, communications, education and other fields, but also are widely used in ships, ports and offshore platforms, often used as emergency and backup power supplies. However, only through regular load detection and maintenance can the high-voltage generator set ensure that the output is normal and meet the work needs.

 For a long time, it is a technical problem to test the load of high voltage generator set above 10kV, and it is necessary to master excellent high voltage detection technology to ensure the safety in the test. Hebei Hanlan Environmental Technology Co., Ltd. tailor-made high-voltage generator set test program for users to adapt to the needs of different environments.

 Genset load testing is to place the generator under different load conditions and see how the machine reacts to power consumption. Although you can use other test generators, load sets provide an accurate test of electrical equipment. If you have to check multiple generators or need regular, reliable testing, using load groups will ensure accurate results. You can easily adjust the power consumption on the generator through controls on the load group, which becomes difficult if you try to create alternatives to power consumption.

 According to the maximum load power of the generator set, N sets of corresponding load devices are selected, and the generator set, control output cabinet and load device are connected by cables. Start the generator set first, gradually load to 25%, 50%, 75%, 100% of the full load according to the data displayed on the control panel to record the water temperature, voltage, current and other data at various stages (generally there are diesel generator load test tables) to see whether the diesel generator set is operating normally at various stages, whether the output current is stable, whether the control output cabinet has the breaking capacity, etc. The specific test time can be determined according to the actual demand of the generator set. If strict testing is required, it is necessary to entrust a third party (such as a technical testing station) to conduct testing and issue relevant test reports.

 High-power high-voltage generator sets have strong output capability and are favored by the market, but there are technical problems in carrying out on-load test on them. When the high-voltage load cabinet is loaded at full load, the heat generated by its ultra-high power is considerable, and the output voltage of the high-voltage generator set reaches 10,000 volts, which is a test for the withstand voltage capability of the load cabinet and can produce qualified high-voltage load cabinets. If the load cabinet safety factor is not good, it cannot guarantee the safety of operators and machines, so the manufacturer of high voltage generator sets is also very cautious in selecting equipment for acceptance test loads.

 In addition to the quality of the load cabinet itself, strict and automated safety protection systems can avoid losses caused by human negligence and are necessary guarantees for safe operation. The load cabinet, which can carry out acceptance test for 10KV and 6KV high-voltage generator sets, is another successful application of automatic security system, which can collect environmental data through high-precision acquisition module and automatically carry out protection action by control chip.

 High voltage load cabinet will be ultra-high power resistor protection package in the container, the internal air duct design is reasonable, both sides of the wind, the top of the wind, to avoid outdoor wind caused by variable wind problems. The top door and side door can be opened and closed freely. After the powerful fan is opened, the heat generated when the 3000KW power is fully loaded can be blown away to ensure that the internal temperature of the load cabinet is controlled within the safety line.

 When the high-voltage generator set test system is loaded, no personnel are required to approach, and the four-fold protection function of the heat dissipation system can automatically protect the load cabinet. When the ventilation door is not opened and the air duct is not smooth, the fan operates abnormally, the temperature in the load cabinet exceeds the warning level, or there is smoke in the load cabinet, the automatic protection function will be turned on, and the loading will be stopped forcibly, leaving only the fan rotating to continue heat dissipation, preventing temperature rise and protecting operation safety. In addition, after the high-voltage load is started, if it is not loaded for a long time, the system will intelligently stop the fan operation to save electricity.

 High-voltage load is also equipped with emergency stop function, through the external console or PC software can be a one-button emergency stop, control load cabinet shutdown. When the emergency stop or protection function is triggered, the load cabinet will continuously sound the alarm. The console and PC software can explain the alarm reason and remind the staff to pay attention. In order to prevent false alarms, or to meet the special test needs of the user, all protection functions can be freely set to switch off the alarm when necessary.

 Hebei Han Lan research and development of high-power marine dry load using automatic dual-channel power supply system, can automatically complete the voltage, phase sequence conversion, adapt to various types of input power. When the load uses shore power supply, if power failure occurs, it can automatically switch to ship power supply to ensure that the test is not interrupted, the data is not lost, and intelligent and efficient power supply management is realized.  

 Through high-power marine dry load, it can be used for comprehensive inspection of marine generator sets and marine power stations. The load has intelligent host computer software, which can quickly control the 6MW load with simple setting, comprehensively test the load of the unit, and detect the dynamic electrical parameters of the unit, such as steady state/transient voltage, frequency regulation rate, recovery time, fluctuation rate, harmonic content and other important parameters, and timely discover whether the unit performance meets the national standard requirements. nbsp; 

 Therefore, shore power technology is a new comprehensive system solution engineering, which provides different ship power supply methods according to different actual conditions. Energy conservation and emission reduction is a strategic measure of our country, especially for the problem of ship port pollution. Our country has put forward the strategy of port transformation and upgrading. Obviously, shore power technology is an important way to realize green emission reduction in ports.
