Description

Technical Field

[0001] The utility model relates to the technical field of high and low voltage switch cabinets, in particular to a high and low voltage switch cabinet. Background Art

[0002] As the name suggests, high and low voltage switchgear is equipment for connecting high-voltage or low-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, which are then stepped down by transformers and then transferred to low-voltage cabinets. The low-voltage cabinets are then transferred to distribution boxes for various electricity users. What is inside is nothing more than some protective devices such as switches and circuit breakers assembled into one electrical equipment.

[0003] Most of the existing high and low voltage switch cabinets are made of stainless steel plates, and various wiring holes and heat dissipation holes are opened on the cabinet. During the daily use of the high and low voltage switch cabinets, especially in rainy or humid weather, there will be a lot of moisture in the air, and the air can penetrate through any hole. When the humid air enters the high and low voltage switch cabinets, it will cause excessive moisture inside the high and low voltage switch cabinets, which may cause short circuits in electrical components. Therefore, the staff will place desiccant inside the high and low voltage switch cabinets, but the staff do not know the hygroscopicity of the desiccant. Replacing the desiccant before it is completely hygroscopic will cause waste, and if the desiccant is saturated with moisture, it will affect the use of the high and low voltage switch cabinets if it is not replaced in time.

DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figures 1 to 6 The utility model provides a technical solution: a high and low voltage switch cabinet, including a high and low voltage switch cabinet body 1, the high and low voltage switch cabinet body 1 is an electrical device, the external line first enters the main control switch in the cabinet, and then enters the branch control switch, each branch is set according to its needs, the bottom of the high and low voltage switch cabinet body 1 is pulled out and installed with a drawer 2, the drawer 2 can be completely pulled out from the high and low voltage switch cabinet body 1, a partition 3 is placed and installed inside the drawer 2, the partition 3 can be taken out downward to block foreign matter, the holes of the partition 3 can pass humid air, the bottom four corners of the inner wall of the drawer 2 are fixedly connected with a first elastic member 8, the first elastic member 8 can be a spring, the top of the first elastic member 8 is fixedly connected with a storage box 5, the storage box 5 is used to store desiccant, the storage box 5 is rotatably connected with two placement boxes 7, the placement box 7 is also used to place desiccant, the desiccant is placed separately up and down, the storage amount of the desiccant can be increased, and it is also convenient for humid air to enter the lower layer, the bottom of the storage box 5 is away from the high and low Two mounting blocks 10 are fixedly connected to one side of the pressure switch cabinet body 1, and a plug rod 11 is slidably connected inside the mounting block 10. One end of the plug rod 11 outside the mounting block 10 is dome-shaped. A second elastic member 12 is installed between the inside of the mounting block 10 and the plug rod 11. The second elastic member 12 can be a spring. The second elastic member 12 can push the plug rod 11 so that the plug rod 11 continues to press against the front inner wall of the drawer 2. A rectangular groove 13 is provided on the front of the drawer 2. The two sides of the interior of the rectangular groove 13 are symmetrically provided with plug holes 15 that cooperate with the plug rod 11. The desiccant inside the storage box 5 and the placement box 7 will become heavier after continuously absorbing moisture from the humid air, and then the storage box 5 moves downward as a whole. The plug rod 11 will be inserted into the inside of the plug hole 15 during the downward sliding process. A warning plate 16 is rotatably connected to the inside of the rectangular groove 13. The warning plate 16 can use eye-catching colors, such as red and yellow, and can also be written with warning words. After the warning plate 16 is flipped over by the plug rod 11, it means that the desiccant needs to be replaced.

[0020] Among them, a bridging bar 6 is fixedly connected between the middle parts of the inner walls of the storage box 5. After the two storage boxes 7 are turned over and laid flat, they can both contact with the bridging bar 6. After the two storage boxes 7 are turned over to be horizontal, they can be placed on the bridging bar 6.

[0021] Among them, a platform 9 is fixedly connected to the inner wall of the drawer 2 and located above the storage box 5. The platform 9 is rectangular and its fixed position is very close to the top edge of the drawer 2. The partition 3 and the platform 9 can be used in conjunction with each other.

[0022] Among them, fixing blocks 4 are symmetrically fixedly connected to both sides of the top of the partition 3, and the partition 3 can be quickly taken out by pinching the fixing blocks 4.

[0023] A stop bar 14 is fixedly connected to the bottom of the rectangular groove 13 and located at the edge away from the drawer 2 .

[0024] Specifically, the required quantitative desiccant will be placed in the storage box 5 and the placement box 7 in advance. During continuous use, the desiccant in the storage box 5 and the placement box 7 will become heavier after continuously absorbing moisture in the humid air. Then the storage box 5 moves downward as a whole. Initially, a part of the insertion rod 11 is inserted into the interior of the mounting block 10, and the second elastic member 12 is also in a contracted state. Then, as the insertion rod 11 slides downward, after sliding to the position of the insertion hole 15, the second elastic member 12 will push the insertion rod 11 to insert into the interior of the insertion hole 15. Then, under the push of the insertion rod 11, the warning plate 16 will rotate out. After seeing the warning plate 16 rotate out, the responsible personnel can pull out the drawer 2, then pinch the fixing block 4 to take out the partition 3, and replace the desiccant in the storage box 5 and the placement box 7. After the replacement is completed, the insertion rod 11 is pushed out of the insertion hole 15, and the storage box 5 can be reset under the push of the first elastic member 8.
