[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figures 1-5 As shown, this utility model provides a technical solution: a power equipment protection device, including a protection component 1, and a drying component 3 installed at the bottom of the protection component 1.

[0020] The protective housing 101 in protective component 1 is made of stainless steel, possessing excellent corrosion resistance and strength, effectively protecting the internal components. The sealing plate 102 on one side of the front of the protective housing 101 is made of transparent acrylic, allowing personnel to easily observe the operation of the internal components. A rubber sealing ring is provided at the connection between the sealing plate 102 and the protective housing 101, further improving the sealing performance of the protective housing 101 and preventing the ingress of external dust, rainwater, etc. The fixing bolts 103 are galvanized bolts to prevent rust and ensure the reliability of the connection.

[0021] The louvers 104 on one side of the protective housing 101 are made of aluminum alloy, with a 5mm spacing between the louvers, ensuring good ventilation while effectively blocking rainwater and larger dust particles from entering. The inner partition 105 is made of insulating plastic and serves to divide the space. The ventilation holes 106 at the bottom of the inner partition 105 have a diameter of 8mm, ensuring smooth circulation of dry air inside the protective housing 101.

[0022] The L-shaped plate 301 in the drying assembly 3 is made of steel plate and is fixed to both sides of the inner bottom surface of the protective shell 101 by welding to ensure its installation stability. Mounting blocks 302 and 303 are both made of iron and are fixed to the top surface of the horizontal portion of the L-shaped plate 301 by bolts. The transmission rod 306 is made of stainless steel, with its two ends rotatably connected to the slider 305 and the storage box 307 via pins, ensuring flexible transmission. The storage box 307 is made of plastic with an open top for easy placement and replacement of the desiccant 308. The desiccant 308 is made of silica gel, which has good moisture absorption properties and is recyclable, reducing operating costs. The spring 309 is a cylindrical helical spring with its elastic coefficient selected according to the weight of the desiccant 308, ensuring that when the desiccant 308 becomes damp and increases in weight to a set level, it can push the slider 305 to slide and trigger the switch 311. The stop lever 310 is a plastic rod, fixed to one side of the slider 305 by adhesive. Its length is set so that when the slider 305 slides to the set position, it can accurately contact the switch 311. The switch 311 is a limit switch, connected to the buzzer alarm 107 via a wire. The buzzer alarm 107 is powered by 220V AC and the alarm volume is set to 80 decibels to ensure that the staff can hear the alarm in time.

[0023] The working process of this power equipment protection device is as follows: In the initial state, the storage box 307 contains a new desiccant 308, the spring 309 is in a naturally extended state, the slider 305 is located at one end of the round rod 304 near the first mounting block 302, the stop rod 310 is not in contact with the switch 311, and the buzzer alarm 107 is not working.

[0024] Over time, the desiccant 308 gradually absorbs moisture from the air inside the protective casing 101, becoming damp and heavier.

[0025] When the weight of the desiccant 308 increases to a set value (e.g., an increase of 500g), the storage box 307 slides down along the groove of the vertical part of the L-shaped plate 301 under the action of gravity.

[0026] The sliding of the storage box 307 causes the transmission rod 306 to rotate, and the transmission rod 306 pushes the slider 305 to slide along the round rod 304 towards the second mounting block 303, and the spring 309 is compressed.

[0027] When slider 305 slides to the set position, the stop rod 310 contacts switch 311, triggering switch 311. Switch 311 controls buzzer alarm 107 to sound an alarm, reminding staff to replace desiccant 308.

[0028] Upon hearing the alarm, the staff unscrewed the fixing bolt 103, opened the sealing plate 102, removed the storage box 307 from the L-shaped plate 301, poured out the damp desiccant 308, and replaced it with a new desiccant 308.

[0029] After the replacement is completed, the storage box 307 is reinstalled onto the L-shaped plate 301. Under the elastic restoring force of the spring 309, the slider 305 slides along the round rod 304 away from the second mounting block 303. The transmission rod 306 drives the storage box 307 to slide upward and reset. The stop rod 310 separates from the switch 311, the buzzer alarm 107 stops sounding, and the device returns to its initial working state.

[0030] An electrical cabinet assembly includes an electrical equipment protection device and a cabinet assembly 2 installed on top of the protection assembly 1.

[0031] The gas-insulated cabinet 201 in cabinet component 2 has a metal shell and is filled with insulating gas to ensure good insulation and arc-extinguishing performance. The cabinet door 202 is hinged to the gas-insulated cabinet 201 and has an observation window for easy monitoring of the internal operation of the gas-insulated cabinet 201. A sealing strip is installed at the connection between the cabinet door 202 and the gas-insulated cabinet 201 to ensure the sealing performance of the gas-insulated cabinet 201. The cable routing blocks 203 are made of insulating plastic and are bolted to one side of the gas-insulated cabinet 201. The spacing between adjacent cable routing blocks 203 is 150mm, and the number of cable routing blocks 203 is rationally arranged according to the number and length of cables inside the gas-insulated cabinet 201.

[0032] The vertical groove at the front of the top of the wiring block 203 facilitates the installation and rotation of the rotating baffle 205. The rotating baffle 205 is made of plastic and is rotatably mounted on the top side of one side of the vertical groove via a pin. The length and width of the rotating baffle 205 are adapted to the vertical groove to ensure complete closure. Both the first magnetic plate 206 and the second magnetic plate 207 are permanent magnets, fixed with glue to one side of the bottom surface of the rotating baffle 205 and one side of the vertical groove, respectively. Their magnetic strength ensures that the rotating baffle 205 will not easily open when closed.

[0033] The wiring process for this power cabinet assembly is as follows: The staff opened the cabinet door 202 of the gas filling cabinet 201 and selected the appropriate cable routing block 203 and cable routing trough 204 according to the specifications and layout requirements of the cables.

[0034] Rotate the baffle 205 by hand to make it rotate around the pin, and the first magnetic plate 206 and the second magnetic plate 207 will separate, opening the vertical groove.

[0035] Place the cable into the cable tray 204, ensuring that the cable is neatly arranged within the cable tray 204 and does not become tangled.

[0036] After the cable is placed, rotate the baffle 205 back to its original position so that the opposite poles of the first magnetic plate 206 and the second magnetic plate 207 are attracted together. Rotate the baffle 205 to close the vertical groove and fix the cable in the cable tray 204.

[0037] Following the steps above, complete the wiring of all cables in sequence, then close cabinet door 202 to complete the wiring operation of the power cabinet components.

[0038] In actual use, the power cabinet assembly provides a good operating environment for the gas-filled cabinet 201 through the protective shell 101 of the power equipment protection device, the louvers 104, the inner partition 105 and the drying component 3, etc., effectively preventing the influence of factors such as moisture and dust on the gas-filled cabinet 201.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
