Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of load boxes, in particular to a medium and high voltage load box. 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] At present, domestic generator assembly plants do not use medium and high voltage load boxes. Existing generator sets emit black smoke and insufficient fuel due to light load of generator sets, carbon deposits on pistons and nozzles, increased wear of cylinders, and reduced overall efficiency. At the same time, there are problems such as underload failure of generator sets and failure to start due to low temperature. In summary, the medium and high voltage load boxes in the existing technology have problems such as large size and heavy weight; not resistant to low temperatures; inconvenient maintenance; and poor reliability.

[0006] Preferably, both sides of the rear of the load box body are rotatably mounted with air inlet plates via a rotating frame, and both sides of the front of the load box body are rotatably connected with air outlet plates via a rotating member.
[0007] Preferably, protective mesh covers are fixedly mounted on both sides of the front and rear of the load box body by bolts, and an air guide cover is fixedly mounted on the outer surface of the driving fan.
[0008] Preferably, electrical modules are provided on both sides of the inner cavity of the load box body and between the two resistance modules, and a sampling module is provided inside the load box body and between the two electrical modules.
[0009] Preferably, a line inlet terminal is provided at the rear of the load box body.
[0010] Preferably, a maintenance compartment is provided inside the load box body and between the two electrical modules.
[0011] Beneficial Effects
[0012] The utility model provides a medium and high voltage load box. Compared with the existing technology, it has the following beneficial effects:
[0013] The utility model adopts multiple sets of fan modules through the whole set of loads, and the load box body can well meet the requirements of waterproofing, oil resistance and high temperature resistance, so that the overall volume of the load box body is smaller, and the fan blades are driven to rotate by multiple driving fans, so that the fan blades blow air into the load box body, and the air is discharged through the air inlet plate and the air outlet plate, so that the heat generated by the load can be quickly transported to the outdoors, and the high-voltage electrical layer is in the maintenance compartment, and the low-voltage incoming line is connected from the side of the maintenance compartment, which can be more convenient for maintenance.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.
[0019] See also Figure 1-3 The utility model provides a technical solution: a medium- and high-voltage load box, comprising a load box body 1, resistance modules 2 are arranged on both sides of the inner cavity of the load box body 1, fan modules 3 are arranged on both sides of the inner cavity of the load box body 1 and behind the resistance modules 2, electrical modules 7 are arranged on both sides of the inner cavity of the load box body 1 and between the two resistance modules 2, a sampling module 9 is arranged inside the load box body 1 and between the two electrical modules 7, an incoming line terminal 8 is arranged at the rear of the load box body 1, and a maintenance compartment 10 is arranged inside the load box body 1 and between the two electrical modules 7.
[0020] Furthermore, in order to quickly ventilate and cool the load box body 1, the fan module 3 includes a driving fan 31, which is fixedly installed at the rear of the resistance module 2 through a fixed frame, and the output shaft of the driving fan 31 is fixedly connected to the fan blades 32 through a coupling, and the two sides of the rear of the load box body 1 are rotatably installed with air inlet plates 4 through a rotating frame, and the two sides of the front of the load box body 1 are rotatably connected with air outlet plates 5 through rotating parts, and the two sides of the front and rear of the load box body 1 are fixedly installed with protective mesh covers 11 through bolts, and the outer surface of the driving fan 31 is fixedly installed with an air guide cover 6.
[0021] It should be noted that the wind is filtered by the protective mesh cover 11 , which can effectively prevent dust from entering the load box body 1 .
[0022] When in use, by opening the two air inlet plates 4 and the air outlet plates 5, the fan 31 is controlled to drive the fan blades 32 to rotate, so that the multiple fan blades 32 rotate to blow air forward, and the external wind enters the load box body 1 through the two air inlet plates 4. The rotating fan blades 32 blow the wind forward. The incoming wind will cool down the resistance module 2. The wind passing through the resistance module 2 will be discharged from the two air outlet plates 5, and the resistance module 2 will be cooled back and forth in sequence. At the same time, the wind entering the load box body 1 will be filtered through multiple protective mesh covers 11.
