The photovoltaic power generation inverter is used as core equipment for power generation of a wind-light power station, the reliability of the photovoltaic power generation inverter directly influences the overall power generation level of the station, sand wind in inner Mongolia areas is frequent, the wind-light power station inverter is influenced by local sand dust, the dust can cover a dust screen, and the problems of power module aging and damage of the inverter caused by dust deposition and high temperature can be caused. The utility model comprises the following components: container box (3), container box top be fixed with radiator fan (4), every dust screen (2) department of container box side all be fixed with rapping device (1), rapping device include backplate (6) and two and shake motor (5), every the output shaft tip of shaking the motor all be fixed with and shake cam (7). The container dust preventing device is used for preventing the container of the photovoltaic power generation inverter from shaking dust.
Description
Technical Field
The utility model relates to a dustproof rapping container of a photovoltaic power generation inverter.
Background
The photovoltaic power generation inverter is used as core equipment for power generation of a wind-light power station, the reliability of the photovoltaic power generation inverter directly influences the overall power generation level of the station, sand wind in inner Mongolia areas is frequent, the wind-light power station inverter is influenced by local sand dust, the dust can cover a dust screen, and the problems of power module aging and damage of the inverter caused by dust deposition and high temperature can be caused.
Disclosure of Invention
The utility model aims to provide a dustproof rapping container for a photovoltaic power generation inverter.
The above purpose is realized by the following technical scheme:
the utility model provides a photovoltaic power generation inverter rapping container that prevents dust, its constitution includes: the container box, container box top be fixed with radiator fan, every dust screen department of container box side all be fixed with rapping device, rapping device include backplate and two motors of rapping, every the output shaft tip of rapping motor all be fixed with the cam of rapping.
The photovoltaic power generation inverter dustproof rapping container is characterized in that the rapping motor is fixed on the back plate through bolts.
Has the advantages that:
1. when the inverter works normally in the daytime, the fan draws air and dissipates heat along with the rise of indoor temperature, and the alternating current bus bar side of the inverter is kept at the ambient temperature all the time. When the inverter is out of operation at night, the inverter control circuit controls the fan to rotate reversely and simultaneously starts the dustproof net rapping device, the dustproof net of the inverter cabinet and the dust of the container dustproof net are blown out of a room by positive pressure generated by the fan, dust covered on the dustproof net can be cleaned, and the temperature in the cabin is obviously reduced after dust is removed, so that the problems of aging and damage of a power module caused by high dust deposition temperature of the inverter can be effectively solved, and the operation reliability of the inverter is improved.
Description of the drawings:
FIG. 1 is a schematic structural view of the present invention;
FIG. 2 is a schematic view of the construction of the rapping device;
FIG. 3 is a schematic view of the construction of the rapping cam;
FIG. 4 is a control schematic of the present invention;
in the figure: 1. a rapping device; 2. a dust screen; 3. a container body; 4. a heat radiation fan; 5. vibrating a motor; 6. a back plate; 7. the cam is rapped.
The specific implementation mode is as follows:
example 1:
the utility model provides a photovoltaic power generation inverter rapping container that prevents dust, its constitution includes: the container box 3, container box top be fixed with radiator fan 4, every dustproof screen 2 department of container box side all be fixed with rapping device 1, rapping device include backplate 6 and two rapping motors 5, every rapping motor's output shaft tip all be fixed with rapping cam 7.
Example 2:
according to the photovoltaic power generation inverter dustproof rapping container in the embodiment 1, the rapping motor is fixed on the back plate through bolts, and the back plate is fixed in the container box body through bolts.
As shown in fig. 3, when the inverter operates normally in daytime, the fan draws air and dissipates heat with the rise of indoor temperature, so that the ac busbar side of the inverter is kept at ambient temperature. When the inverter quits operation at night, the inverter control circuit controls the fan to rotate reversely and simultaneously starts the dustproof net rapping device, and dust on the dustproof net of the inverter cabinet and dust on the dustproof net of the container are blown out of a room by positive pressure generated by the fan;
the method is characterized in that a thermal relay is additionally arranged on a fan power supply loop, when a fan is jammed and locked, the current of the power supply loop is steeply increased, the thermal relay performs protection action, a fan contactor under linkage control is disconnected, an auxiliary signal is sent to a main control board, the main control board gives an alarm and stops an inverter to run, the DSP software needs to be upgraded during transformation, the thermal relay protection is connected into a main control system, and in order to prevent misoperation, after a control strategy is that a fault is reported, equipment is shut down and does not reset automatically, and manual recovery is needed after field inspection.
Claims (2)
