[0028] 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.

[0029] like Figures 1 to 12 As shown, this utility model provides a frame-type suspended air metering cabinet, including a cabinet frame 1, a triangular plate 2 fixedly connected to the inner cavity of the cabinet frame 1, a base 3 fixedly connected to the bottom end of the cabinet frame 1, a supporting channel steel 4 fixedly connected to the middle of the base 3, a pressure relief hole 5 opened in the inner cavity of the base 3, multiple supports are provided inside the cabinet frame 1, lifting rods 6 are fixedly connected to both the left and right sides of the base 3, a high-voltage insulator 7 is fixedly connected to the inner cavity of the cabinet frame 1, a metering current transformer 8 is fixedly connected to the top of the supporting channel steel 4, frame beams 9 are fixedly connected to both the upper and lower ends of the front side of the inner cavity of the cabinet frame 1, and a central beam 10 is fixedly connected to the center of the front side of the inner cavity of the cabinet frame 1.

[0030] By adding triangular plates 2 at the right-angle connection points of the cabinet frame 1 to enhance its strength, the skeleton shape of the cabinet frame 1 can be constructed. Then, the bracket, high-voltage insulator 7, metering current transformer 8, frame beam 9, and middle beam 10 are installed on the cabinet frame 1, which further improves the overall rigidity of the cabinet frame 1. Then, by connecting the lifting equipment with the lifting rod 6, the cabinet frame 1 can be lifted more firmly and reliably.

[0031] The cabinet frame 1 is equipped with electrical components such as high-voltage insulators 7 and metering current transformers 8 connected to the cabinet frame 1 to ensure a safe electrical distance of 320mm air insulation.

[0032] The cabinet frame 1 has a cabinet door 11 on the front side, a bolt lock 12 on the lower right side of the cabinet door 11, an electromagnetic lock 13 and a lead lock 14 on the left side of the cabinet door 11, and a cable room observation window 15 and a display 16 on the upper left side of the cabinet door 11.

[0033] The left cabinet door 11 is equipped with an electromagnetic lock 13 and a lead lock 14, while the right cabinet door 11 has a manual bolt lock 12 on the inside, operated from the inside. Door control is in place, restricting the operation sequence through electrical and mechanical locks. The right cabinet door 11 must be closed and locked first, then the left cabinet door 11 must be closed, and the electromagnetic lock 13 will lock. To open the door, the electromagnetic lock 13 must be unlocked first, then the left cabinet door 11 opened, and finally the bolt lock 12 unlocked from the inside to open the right cabinet door 11. This forms an interlocking closed loop, ensuring the reliability of the five-proof system.

[0034] Among them, the top of the cabinet frame 1 is fixedly connected to the instrument room 17, the front side of the instrument room 17 is fixedly connected to the upper observation window 18, the top of the cabinet frame 1 is fixedly connected to the busbar room 19, the upper observation window 18 is located on the rear side of the instrument room 17, and the top of the cabinet frame 1 is provided with lead seal screws 20.

[0035] The electrical components inside the instrument room 17 can be observed through the observation window 18 above. The busbar cable is installed through the busbar room 19. The busbar cable bushing and the high-voltage switchgear are misaligned in the depth direction. The ABC three-phase incoming and outgoing lines are connected to the busbar through two separate independent bushings. The busbar terminal joint is used to avoid busbar T-type joints at special angles.

[0036] Among them, a sealing plate 21 is provided on the outside of the cabinet frame 1. A moisture absorption chamber 22 is fixedly connected to the side of the sealing plate 21 away from the cabinet frame 1. A moisture-proof frame 23 is slidably connected to the inner cavity of the moisture absorption chamber 22. A round rod 24 is fixedly connected to the top of the inner cavity of the moisture-proof frame 23. A moisture-absorbing bag 25 is hung on the surface of the round rod 24. A water collection bag 26 is fixedly connected to the bottom of the moisture-absorbing bag 25.

[0037] After the calcium chloride particles inside the moisture-absorbing bag 25 absorb the moisture in the air inside the cabinet frame 1, the water flows into the inner cavity of the water collection bag 26 for collection. When all the calcium chloride particles inside the moisture-absorbing bag 25 have turned into water, the moisture-proof frame 23 is pulled out from the inner cavity of the moisture-absorbing chamber 22, and then the moisture-absorbing bag 25 is removed from the surface of the round rod 24 for replacement. In this way, the moisture-absorbing bag 25 removes moisture from the air inside the cabinet frame 1, thereby avoiding the situation where the electrical components inside the cabinet frame 1 are damaged due to high humidity in the air.

[0038] The moisture-absorbing bag 25 contains calcium chloride granules and is made of breathable PTE water-locking paper.

[0039] Air from inside the cabinet frame 1 passes through the moisture-absorbing bag 25 and comes into contact with the calcium chloride particles inside the moisture-absorbing bag 25. After the calcium chloride particles come into contact with the moisture in the air, they absorb the moisture and turn it into water, which enters the inner cavity of the water collection bag 26.

[0040] The moisture absorption chamber 22 has guide grooves on both the upper and lower sides of its inner cavity. The moisture-proof frame 23 is slidably connected to the inner cavity of the moisture absorption chamber 22 through the guide grooves. A handle is fixedly connected to the rear side of the moisture-proof frame 23.

[0041] After the calcium chloride granules inside the moisture-absorbing bag 25 are used up, the staff can pull the handle to remove the moisture-proof frame 23 from the inside of the moisture-absorbing chamber 22, and then replace the moisture-absorbing bag 25 and the water collection bag 26, which improves the convenience of the staff during replacement.

[0042] Among them, magnetic plates 27 are fixedly connected to the front side of the moisture-proof frame 23 and the front side of the inner cavity of the moisture-absorbing chamber 22, and the moisture-absorbing chamber 22 and the moisture-proof frame 23 are magnetically connected by magnetic plates 27.

[0043] The magnetic suction plate 27 improves the stability of the moisture-proof frame 23 when it is located in the inner cavity of the moisture-absorbing chamber 22, and prevents the moisture-proof frame 23 from falling out of the inner cavity of the moisture-absorbing chamber 22 during the lifting of the cabinet frame 1.

[0044] Among them, cabinet door 11 is a double door type, the central crossbeam 10 is located in the middle of cabinet door 11, and the frame crossbeams 9 are located above and below cabinet door 11 respectively.

[0045] The structural strength between the middle part of the cabinet frame 1 and the cabinet door 11 is increased by the central crossbeam 10, and the structural strength of the upper and lower sides of the cabinet door 11 is improved by the frame crossbeam 9, thereby improving the overall structural strength in conjunction with the cabinet frame 1.

[0046] The working principle and usage process of this utility model are as follows: The current transformer 8 is installed above the inner cavity of the cabinet frame 1 and above the supporting channel steel 4, and the support strength at the chamfer of the cabinet frame 1 is increased by the triangular plate 2.

[0047] The outer side of the cabinet frame 1 is enclosed by the sealing plate 21. The cabinet doors 11 are double doors. The frame beams 9 enhance the normal strength of the top and bottom of the cabinet doors 11, and the middle beams 10 enhance the structural strength between the two cabinet doors 11. The left cabinet door 11 is equipped with an electromagnetic lock 13 and a lead lock 14, while the right cabinet door 11 has a manual bolt lock 12 on the inside, operated from the inside. Door control is provided, restricting the operation sequence through electrical and mechanical locks. The right cabinet door 11 must be closed and locked first, then the left cabinet door 11 must be closed and the electromagnetic lock 13 locked. To open the door, the electromagnetic lock 13 must be unlocked first, the left cabinet door 11 opened, and then the bolt lock 12 is unlocked from the inside to open the right cabinet door 11. This forms an interlocking closed loop, ensuring the reliability of the five-proof system.

[0048] The cabinet frame 1 is equipped with electrical components such as high-voltage insulators 7 and metering current transformers 8 connected to the cabinet frame 1 to ensure a safe electrical distance of 320mm air insulation. The overall rigidity of the cabinet frame 1 is improved by the support frame and frame beams 9 on the cabinet frame 1.

[0049] Next, the cable is placed in the cable chamber below the inner cavity of the cabinet frame 1, and connected with a busbar terminal connector to avoid busbar T-type connectors at special angles.

[0050] When lifting is required, the lifting equipment lifts the cabinet frame 1 using the lifting rod 6.
