Description

Technical Field

[0001] The invention belongs to the technical field of power grids, and in particular relates to a switch fuse structure of a ground-mounted grid-connected cabinet. Background Art

[0002] A grid-connected cabinet is a device used in power systems. Its main function is to convert the DC power generated by multiple power generation devices (such as solar panels, wind turbines, etc.) into AC power and connect it to the public power grid. Such a device is usually called an inverter. The working principle of a grid-connected cabinet is to convert the DC power from the power generation equipment into AC power and then synchronize it to the public power grid. This conversion process needs to be completed by an inverter, which converts DC power into AC power and adjusts the output voltage, frequency and phase according to the parameters of the public power grid to ensure the stable operation of the power system. In modern power systems, the use of grid-connected cabinets can effectively incorporate the power generated by renewable energy (such as solar and wind power) into the power network, thereby reducing dependence on traditional fossil fuels, reducing carbon emissions, and promoting the use and development of sustainable energy. Grid-connected cabinets usually have monitoring, protection and communication functions, and can monitor the state of the power grid, power quality, current load and other parameters in real time, and take measures to protect the safe and stable operation of the power system when necessary. However, general grid-connected cabinets do not have a good insurance structure to protect users, have certain safety hazards, and cannot quickly discover problems and repair them in time.

[0003] The existing authorization number is CN211670511U. The present invention discloses a grid-connected cabinet for power grid connection, including a grid-connected cabinet body, a fan is fixedly connected to the front end of the grid-connected cabinet body, a vent is provided inside the grid-connected cabinet body, a filter is fixedly connected inside the vent, a rotating shaft is fixedly connected to the rear end of the grid-connected cabinet body, a sealing plate is sleeved on the outer wall of the rotating shaft, and a sealing pad is glued to the front end of the sealing plate. The present invention starts the fan by pulling the sealing plate, and the grid-connected cabinet body can be dissipated at this time. Through the effect of the filter, a large amount of dust can be prevented from entering the device. When the device is closed, the sealing plate is attached to the grid-connected cabinet body. The above device solves the problem that the device is prone to generate a lot of heat during operation, resulting in excessively high internal temperature of the device, which reduces the service life of the device, ensures the sealing of the device when not in use, reduces the internal temperature of the device when in use, and prolongs the service life of the device.
