DETAILED DESCRIPTION

[0025] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0026] like Figure 1 - Figure 6 A safe and energy-saving high-voltage switch cabinet shown in the figure comprises a cabinet body 1, a plurality of partitions 2 are arranged inside the cabinet body 1, a plurality of installation chambers 3 are formed between the partitions 2 and the cabinet body 1, two mobile racks 6 are slidably connected inside one of the installation chambers 3, a mounting plate 7 is installed between the two mobile racks 6, a connecting mechanism is arranged at the connection between the mobile rack 6 and the mounting plate 7, the connecting mechanism can connect the mobile rack 6 with the mounting plate 7, the height of the mounting plate 7 can be conveniently adjusted inside the mobile rack 6, the installation space of the installation chamber 3 is reasonably utilized, and necessary electrical components can be installed as much as possible while facilitating maintenance.

[0027] The connecting mechanism includes an inner hole 9 arranged on both sides of the mounting plate 7, a limiting block 10 is fixedly connected to the opening of the inner hole 9, an elastic member 11 is arranged inside the inner hole 9, a clamping block 12 is fixedly connected to the end of the elastic member 11 away from the inner hole 9, a shifting block 13 is fixedly connected to the end of the clamping block 12 arranged inside the inner hole 9, and a shifting groove 14 is arranged on the two end faces of the mounting plate 7; the mounting plate 7 can be raised and lowered on the movable frame 6 through the connecting mechanism, but the descent will be restricted by the protrusion 18, and the shifting block 13 can cancel the cooperation between the clamping block 12 and the protrusion 18, so that the mounting plate 7 can be raised, and the adjustment method is simple and fast, and the installation space inside the mounting room 3 can be adjusted at any time according to practical needs, which is convenient for adding or replacing new electrical components in the high-voltage switch cabinet.

[0028] The connecting mechanism also includes a mounting groove 15 arranged at the top of the mobile frame 6, and a limiting groove 16 and a limiting plate 17 are arranged inside the mobile frame 6. A protrusion 18 is fixedly connected to the side of the limiting plate 17 close to the limiting groove 16. The protrusion 18 cooperates with the block 12. The limiting effect of the protrusion 18 on the block 12 can prevent the mounting plate 7 from falling during the use of the switch cabinet and protect the electrical components on the mounting plate 7. The limiting plate 17 and the limiting groove 16 can limit the mounting plate 7 to ensure that the mounting plate 7 will not fall off when the height is adjusted. The mounting plate 7 can only be removed when the mounting plate 7 rises to the position of the mounting groove 15. Similarly, when installing multiple mounting plates 7, it is also necessary to pass through the mounting groove 15 to enter the mobile frame 6.

[0029] A moving mechanism is provided inside the partition 2, and the moving mechanism can control the movement of the moving rack 6 and pull the moving rack 6 out to the cabinet door, so as to facilitate the maintenance of the electrical components installed on the mounting plate 7 and prevent the internal space of the mounting room 3 from being insufficient, which causes trouble for maintenance. The moving mechanism includes sliding holes 22 provided on both sides of the partition 2, and the internal sliding connection of the sliding holes 22 is connected with a connecting rod 20. Slide grooves 21 are provided on both sides of the partition 2, and a connecting block 19 is fixedly installed at one end of the connecting rod 20 close to the inside of the mounting room 3. When the moving mechanism moves the electrical components out, it can not only increase the maintenance space, but also protect the maintenance personnel to prevent the maintenance personnel from accidentally touching the components due to insufficient space, thereby causing the risk of electric shock.

[0030] The connecting rod 20 is arranged inside the slide groove 21, and the connecting block 19 is fixedly connected to the end face of the mobile frame 6. The mobile frame 6 is located inside the slide groove 21 and is in a sliding connection with the slide groove 21 through the connecting rod 20. The slide groove 21 can not only provide conditions for the movement of the mobile frame 6, but also limit the mobile frame 6 to prevent the mobile frame 6 from tilting during movement and causing the electrical components on the mounting plate 7 to fall off.

[0031] A limiting mechanism is provided inside the partition 2, and the limiting mechanism includes an internal thread 23 arranged inside the sliding hole 22. The sliding hole 22 is connected to a fixed knob 24 through a thread. The limiting mechanism can limit the connecting rod 20 and prevent the movable frame 6 from moving. The movable frame 6 can only move when the fixed knob 24 in the limiting mechanism is removed.

[0032] The fixing knob 24 is connected to the sliding hole 22 through the internal thread 23. When the fixing knob 24 is located inside the sliding hole 22, it fits with the end face of the connecting rod 20. During routine maintenance, the electrical components located on the edge of the installation room 3 will be blocked by the inner wall of the switch cabinet and are not convenient for maintenance. At this time, the fixing knob 24 can be removed to move the movable frame 6 out, and at the same time drive the mounting plate 7 and the installed electrical components to be moved out. At this time, the electrical components at various positions can be conveniently maintained.

[0033] An auxiliary mechanism is arranged inside the cabinet 1, and the auxiliary mechanism includes a compression elastic member 25 arranged inside the cabinet 1. The compression elastic member 25 and the partition 2 are located on the same horizontal plane. The compression elastic member 25 acts on the movable frame 6 and is located on the end face opposite to the connecting rod 20. After the limiting mechanism is removed, the auxiliary mechanism can use its own elastic force to pop out the movable frame 6 and the connecting rod 20 a short distance, so that the maintenance personnel can hold the connecting rod 20 and pull out the movable frame 6.

[0034] A trolley 4 is slidably connected to the interior of another installation chamber 3, and a circuit breaker 5 is fixedly installed on the top of the trolley 4. The circuit breaker 5 is located inside the installation chamber 3, and the circuit breaker 5 also adopts a removable installation method. When the circuit breaker 5 needs to be repaired or replaced, the operation can be conveniently performed by moving the trolley 4 without disassembling the entire cabinet 1, thereby improving the convenience and safety of maintenance.

[0035] A plurality of mounting holes 8 are provided on the surface of the mounting plate 7, the clamping block 12 is in a sliding connection with the inner hole 9, and the shifting block 13 is arranged inside the shifting groove 14. By adjusting the shifting block 13, the cooperation between the clamping block 12 and the protrusion 18 can be cancelled, and the restriction of the protrusion 18 on the clamping block 12 can be cancelled, so that the mounting plate 7 can be adjusted to a rising height on the movable frame 6 conveniently, and the mounting plate 7 can also be removed conveniently.

[0036] Working principle: When it is necessary to add or replace new electrical components in the high-voltage switch cabinet, it is first necessary to cut off the power supply to the high-voltage switch cabinet to ensure the safety of the installers, then remove the limiting mechanism, use the exposed connecting rod 20 to pull out the movable frame 6, and then choose to increase or decrease the number of mounting plates 7 according to the number of electrical components to be installed. When increasing the number of mounting plates 7, align the mounting plates 7 with the mounting grooves 15 on the movable frame 6 and push the mounting plates 7 into the movable frame 6 to complete the addition of the mounting plates 7. When it is necessary to reduce the number of mounting plates 7, it is necessary to manually move the dial block 13 to retract the card block 12 into the inner hole 9, and at the same time cancel the cooperation between the card block 12 and the protrusion 18, and then push the mounting plate 7 upward until it reaches the mounting groove 15, then the mounting plate 7 can be removed, the electrical components can be installed or removed, and finally, after using the connecting rod 20 to push the movable frame 6 back into the interior of the switch cabinet, the movable frame 6 can be restricted again by the limiting mechanism to complete the work of adding or replacing new electrical components in the high-voltage switch cabinet.
