Description

Technical Field

[0001] The utility model relates to the technical field of generator set (power station) maintenance, in particular to a generator set (power station) matching dummy load. Background Art

[0002] Diesel generator sets serve as emergency backup power sources after power outages and as common power sources for field equipment that basically relies entirely on generator sets to provide electricity. Most of the time, they are in standby mode. Once a power outage or utility power failure occurs, the units are required to be able to "start up and supply power", and the standby diesel generator sets play a vital role.

[0003] However, the existing generator sets do not have matching dummy load devices. Since the generator set capacity is designed according to the maximum load, in some modes, the load is relatively small, and the generator set capacity is too large. The generator set will emit black smoke when working at non-rated power for a long time. In addition, under low temperature environmental conditions, the coolant temperature is difficult to reach the rated range. The diesel engine has been working in a cold state, which will put the generator set in a light load state. The light load of the generator set will cause insufficient fuel, carbon deposits on the piston and nozzle, increased wear of the cylinder body, and reduced overall efficiency.

[0004] To this end, we provide a generator set (power station) matching dummy load to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0027] A resistance module 2 is arranged inside the box 1, which can configure a dummy load for the generator system, so that the entire power supply system is in the most optimized working condition. The resistance module 2 is installed on the mounting rod 104 by bolts. A fan module 3 is arranged inside the box 1. The fan module 3 can cool the resistance module 2. The fan module 3 includes a cooling fan 301. A threaded hole is opened in the cooling fan 301. The cooling fan 301 is installed to the lower end of the mounting plate 102 by bolts. When the cooling fan 301 is started, the outside air can be sucked into the device, so that the air circulates, thereby taking away the heat generated by the resistance module 2 and cooling it. The cooling fan 301 is bolted with a wind pressure protection device 302. The wind pressure protection device 302 is connected to the cooling fan 301 by bolts. The protection device 302 can monitor the air volume generated by the cooling fan 301, so as to calculate the wind pressure. The wind pressure protection device 302 includes a support frame 303, on which a fixing frame 304 is fixedly connected, and a counter 305 is clamped inside the fixing frame 304. A fan blade 306 is arranged at the lower end of the counter 305. The support frame 303 can create a certain distance between the fan blade 306 and the cooling fan 301, so as to facilitate the wind generated by the cooling fan 301 to drive the fan blade 306 to rotate. The fixing frame 304 is used to install the counter 305. The counter 305 can record the number of rotations of the fan blade 306 in unit time, so as to calculate the wind speed generated by the cooling fan 301.

[0028] An air duct 4 is fixedly connected to the upper end of the box body 1, and the air duct 4 can guide the wind that absorbs heat out of the device. An air outlet 401 is arranged on the side end of the air duct 4, which can effectively prevent rainwater from entering the device through the air outlet 401. A thermostat 402 is arranged in the air outlet 401, and the thermostat 402 is connected to the cooling fan 301 through a wire. When the temperature in the box body 1 rises, it can control the cooling fan 301 to rotate faster to quickly dissipate heat. An air inlet 5 is arranged at the lower end of the box body 1, and the air outlet 401 and the air inlet 5 are both provided with a protective mesh cover 7 to prevent leaves and flying insects from entering the device. A bottom sealing plate 6 is bolted to the lower end of the box body 1, and a protective mesh cover 7 is arranged inside the bottom sealing plate 6. The bottom sealing plate 6 can be disassembled to facilitate the replacement of the wind pressure protection device 302.

[0029] Working principle: The resistor module 2 can configure a dummy load for the generator system, and can work in coordination with the load of the generator to optimize the entire power supply system. In addition, the dummy load can perform regular load maintenance on the generator set, thereby eliminating carbon deposition, so as to timely detect aging components and eliminate faults and hidden dangers.

[0030] Start the cooling fan 301, and the outside air enters the box body 1 through the air inlet 5. The protective mesh cover 7 can block leaves or flying insects from entering to prevent them from damaging the resistor module 2. The wind generated by the cooling fan 301 will drive the fan blades 306 to rotate. The fan blade 306 rotation counter 305 can record the number of revolutions it rotates per unit time, so as to calculate the current wind pressure in the box body 1. The wind flows through the surface of the resistor module 2 to take away the heat, then flows into the air guide 4 and is finally discharged from the air outlet 401. The thermostat 402 in the air outlet 401 can monitor the temperature in the box body 1. When the temperature is too high, the cooling fan 301 can be controlled to speed up, so as to achieve the effect of rapid heat dissipation.
