Description

Technical Field

[0001] The utility model belongs to the technical field of power grids and relates to a power grid protection device. Background Art

[0002] The whole of the power system, which consists of substations and transmission and distribution lines of various voltages, is called a power grid, which mainly includes three units: substation, transmission, and distribution. The task of the power grid is to transmit and distribute electric energy and change the voltage. In the microgrids of some factories, if the power grid fails, the voltage drops and the electric energy cannot be reasonably distributed, which will reduce the output of the products produced and the quality cannot be guaranteed. Therefore, in order to protect the safety of the entire power grid and ensure the stable transmission and distribution of electric energy, it is necessary to design a power grid protection device. Summary of the invention

[0003] The utility model aims to solve the above problems in the prior art and proposes a power grid protection device.

[0004] The purpose of the utility model can be achieved through the following technical solutions: a power grid protection device, including a chassis, characterized in that a transformer is installed in the chassis, one side of the transformer is connected to an external input module through a plurality of input cables, and the other side of the transformer is connected to an external output module through a plurality of output cables, a power storage device is also arranged next to the transformer, one side of the power storage device is connected to the transformer through a transmission cable, and the other side of the power storage device is connected to the output module through output cable 2, an air intake filter is arranged on the top of the chassis, and an air outlet mechanism is arranged on the back of the chassis.

[0005] The working principle of the utility model is as follows: electric energy is input into the transformer from the input cable and then outputted by the output cable. During this period, the storage device is charged through the transmission cable 1 so that it stores a certain amount of electric energy. When the power grid fails and the electric energy is unstable, the output cable 1 stops outputting electric energy to the external output module and switches to the storage device to output stable electric energy to the external output module through the output cable 2 in a short time. During the operation of the power grid, the heat inside the chassis is dissipated through the cooperation of the air outlet mechanism and the air intake filter.

[0006] The air outlet mechanism comprises a shell, which is slidably mounted on the frame through a sliding structure, and an air outlet is provided on the shell, and an exhaust fan is installed inside the air outlet.

[0007] With the above structure, the hot air in the chassis is discharged through the exhaust fan to achieve heat dissipation; when not in use, the shell can be retracted into the chassis to prevent dust from entering.

[0008] The air intake filter is installed on the frame through a snap-fit ​​structure.

[0009] The above structure makes it easy to remove and replace the filter.

[0010] The chassis as a whole is formed by splicing various panels together through bolts.

[0011] The above structure is adopted to facilitate the installation and disassembly of the entire chassis.

[0012] A guide plate is also installed at the air outlet.

[0013] The above structure is adopted to guide the exhausted hot air.

[0014] Compared with the prior art, the power grid protection device has the following advantages: the utility model is equipped with a power storage device, so when a power grid failure occurs, it can provide stable electric energy in a short time, ensure the voltage of the factory's production equipment, thereby ensuring the production capacity of its products, and at the same time buy a certain amount of time for the maintenance of the power grid; the heat dissipation structure on its chassis can also dissipate heat well.
