Prevention of accidental opening or closing of disconnecting switches under load; 3. Prevention of personnel accidentally entering energized compartments; 4. Prevention of closing grounding switches while energized; 5. Prevention of grounding switches closing and energizing.

[0003] Grounding switches are installed in switchgear, typically located next to the disconnect switches on both sides of the circuit breaker. They serve to ground the circuit breaker during maintenance and provide safety protection for personnel during high-voltage equipment and line maintenance. Grounding switches must be used during electrical equipment maintenance; they are generally opened before energizing and closed before shutdown (maintenance). A main shaft is installed on the grounding switch to control its opening and closing. An operating hole corresponding to the main shaft is provided on the switchgear wall. According to the "Electrical Safety Five Protections" regulations, an operating handle must be inserted into the operating hole before opening the cabinet door.

[0029] This utility model proposes an armored switch cabinet with five-proof interlocking functions.

[0030] Please refer to Figures 1 to 3 The armored switchgear with five-proof interlocking functions includes a cabinet body 1, a cabinet compartment 3, a grounding switch 4 installed in the cabinet compartment 3, and a cabinet door 2 hinged to the cabinet body 1 for closing the cabinet compartment 3; a grounding shaft 5 is installed on the grounding switch 4, which is used to drive the grounding switch 4 to open or close; one end of the grounding shaft 5 is coaxially connected to a first bevel gear 6; a transmission shaft 7 and a drive shaft 12 are also installed in the cabinet compartment 3; one end of the transmission shaft 7 is coaxially connected to a second bevel gear 8 that meshes with the first bevel gear 6, and the other end is connected to a locking block 10; An L-shaped block 11 is provided on the door 2; a locking block 10 is used to rotate to engage with the L-shaped block 11 to restrict the opening of the cabinet door 2; an operation hole 14 is provided through the side panel 24 of the cabinet body 1; a third bevel gear 9 is coaxially connected to the drive shaft 7; a fourth bevel gear 13 that meshes with the third bevel gear 9 is coaxially connected to one end of the drive shaft 12, and the other end is directly opposite the operation hole 14; a blocking component is provided between the drive shaft 12 and the operation hole 14, which is used to block the operation hole 14 when the cabinet door 2 is open, and no longer blocks the operation hole 14 when the cabinet door 2 is closed.

A third bevel gear 9 is also coaxially connected to the transmission shaft 7. A fourth bevel gear 13 that meshes with the third bevel gear 9 is provided at one end of the drive shaft 12, and the other end can be connected to the operating handle. When the grounding switch 4 is open, the locking block 10 engages with the L-shaped block 11, and the cabinet door 2 cannot be opened. When the drive shaft 12 is rotated by the operating handle, the drive shaft 12 can drive the transmission shaft 7 to rotate.

Specifically, the locking block 10 is perpendicular to the drive shaft 7. In one embodiment, when the cabinet door 2 is closed, the first panel and the side panel 24 are parallel to each other, so that the locking block 10 can rotate between the second panel and the cabinet door 2 regardless of whether it rotates clockwise or counterclockwise.

[0034] The armored switchgear with five-proof interlocking function also includes multiple support components; the drive shaft 7 and the drive shaft 12 are both set in the cabinet 3 through the support components; the support components include bearing seats 20 and support columns 21; one end of the support column 21 is vertically connected to the bottom wall of the cabinet 3, and the other end is connected to the bearing seat 20; the drive shaft 7 and the drive shaft 12 are both rotatably inserted through the bearing seat 20.

This configuration allows the movable plate to block the through hole 23 when no opening or closing operation is required, preventing foreign objects from entering the cabinet compartment 3. Specifically, a rotating support is provided on the side of the baffle 15 away from the vehicle plate 24, and the rotating support is located above the through hole 23; the baffle 15 is rotatably connected to the rotating support.

[0041] A connecting portion is provided at the end of the drive shaft 12 away from the fourth bevel gear 13; the operating handle can be connected to the connecting portion to drive the drive shaft 12 to rotate. In one embodiment, the connecting portion is provided with a hexagonal groove for matching and engaging with the hexagonal protrusion of the operating handle, and the hexagonal protrusion of the operating handle is inserted into the hexagonal groove to drive the drive shaft 12 to rotate.
