The intelligent large power grid fault detection device also includes: a protective device 2, which is arranged above the shell 5; a heat dissipation device 3, which is installed above the shell 5; and a mounting device 4, which is installed below both sides of the shell 5; wherein the protective device 2 can improve the overall protection strength of the intelligent large power grid fault detection device, the heat dissipation device 3 can improve the heat dissipation efficiency of the intelligent large power grid fault detection device, and the mounting device 4 can quickly mount the shell 5 component on the top of the bottom plate 1;

[0024] In the specific implementation process, it is worth pointing out that the detection component 8, the control module 7 and the detection module 6 can monitor the external power grid in real time.

The installation device 4 can quickly install the components such as the housing 5 on the top of the base plate 1, thereby improving the overall installation efficiency.

[0025] Furthermore, mounting holes are processed at the four corners of the bottom plate 1, and a rubber pad 9 is installed in the bottom groove of the bottom plate 1;

[0026] In the specific implementation process, it is worth pointing out that the staff can install the intelligent large power grid fault detection device on the external facilities through the installation holes using external bolts, and the rubber pad 9 can improve the installation stability of the bottom plate 1 and the external facilities. It can be understood that the installation holes provided in this embodiment are only one possible implementation method for fixing the external installation facilities, not all embodiments. In the specific implementation process, other structures can also be used, and the selection of the specific structure can be reasonably designed according to the actual situation;

[0027] Specifically, when using the intelligent large power grid fault detection device, the staff first installs the shell 5 and other components on the top of the base plate 1 using the installation device 4, and then uses the base plate 1 to install the intelligent large power grid fault detection device on external facilities, and then connects the external power grid to the intelligent large power grid fault detection device, and then the monitoring work can be carried out. When in use, the protective device 2 can protect it and improve the impact resistance of the intelligent large power grid fault detection device, and the heat dissipation device 3 can speed up the air flow rate inside the shell 5, and then the interior of the shell 5 can be cooled.

[0028] Embodiment 2: By Figure 1 , 2 , 3 and 4, the protection device 2 includes: a protection box 201, which is sleeved on the top of the shell 5; a plurality of sleeves 202, which are respectively installed at the four corners of the top of the inner wall of the protection box 201; a plurality of vertical rods 203, which are respectively inserted into the inner walls of the plurality of sleeves 202 and are fixedly connected to the outer wall of the shell 5; a plurality of springs 204, which are respectively sleeved on the outer walls of the plurality of vertical rods 203 and are respectively fixedly connected to the bottoms of the plurality of sleeves 202; wherein the protection box 201 can drive the sleeves 202 to move along the outer wall of the vertical rods 203 and compress the springs 204 at the same time;

At this time, the elastic force of the spring 204 can be used for buffering protection. At the same time, the friction between the vertical rod 203 and the sleeve 202 can consume the elastic potential energy of the spring 204, so that the protective box 201 can quickly stabilize.

[0031] Embodiment 3: By Figure 2 , 3 As can be seen from Figures 4, the heat dissipation device 3 includes: a first filter 301, embedded in the top of the shell 5; a support plate 302, installed on the top of the inner wall of the shell 5; a heat dissipation fan 303, the model of which is not specifically limited, and can be detachably connected to the inner wall of the support plate 302 as long as it meets the use requirements; two second filters 304 are provided, which are respectively embedded in both sides of the shell 5; wherein the heat dissipation fan 303 can draw the air filtered by the first filter 301 into the interior of the shell 5, thereby accelerating the air flow rate inside the shell 5;

[0032] In the specific implementation process, it is worth pointing out that the mesh numbers of the first filter 301 and the second filter 304 are not specifically limited, and can meet the use requirements. The heat dissipation fan 303 can draw external air into the interior of the housing 5, thereby accelerating the air flow rate inside the housing 5, and further cooling the electrical components inside the housing 5;

[0033] Specifically, based on the above-mentioned embodiment 1, when the electrical components inside the outer shell 5 are cooled down, the staff turns on the external power supply of the cooling fan 303. At this time, the cooling fan 303 can draw the external air filtered by the first filter 301 into the interior of the outer shell 5. At this time, the air flow rate on the surface of the electrical components inside the outer shell 5 is accelerated, thereby achieving cooling. Then, the air is discharged from the interior of the outer shell 5 through the second filter 304.

[0035] In the specific implementation process, it is worth pointing out that the two clamping plates 401 can limit the housing 5 and the bottom plate 1, and do not need to be fixed with bolts, thereby greatly reducing the difficulty of installation;

[0036] Specifically, based on the above-mentioned embodiment 1, when installing the intelligent large power grid fault detection device, the staff places the shell 5 on the top of the base plate 1, and then the staff holds the card plate 401 by hand, and then twists the threaded rod 402. At this time, the threaded rod 402 can move along the inner wall of the support plate 403, and at the same time drive the card plate 401 to move. When the card plate 401 is sleeved under the outer wall of the shell 5, the staff releases the hand holding the card plate 401, and then continues to twist the threaded rod 402. When the card plate 401 is tightly against the outer wall of the shell 5, the installation work can be completed.
