Description

Technical Field

[0001] The invention relates to the technical field of switch cabinets, and in particular to an intelligent control system for a high-voltage switch cabinet. Background Art

[0002] High-voltage switchgear refers to electrical products that play the role of switching, controlling or protecting in power generation, transmission, distribution, power conversion and consumption of power systems, and its voltage level is between 3.6kV and 550kV. High-voltage switchgear mainly includes high-voltage circuit breakers, high-voltage disconnectors and grounding switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and other categories.

[0003] During the use of high-voltage switchgear, in order to keep the inside of the switchgear dry and avoid excessive moisture corrosion and damage to the internal electrical equipment, desiccant is generally placed in the switchgear to absorb water molecules in the air, which effectively reduces the humidity in the switchgear. However, the use of desiccant is limited. When the desiccant absorbs a large amount of water molecules, its drying properties will weaken or even disappear. At this time, the desiccant needs to be replaced. However, the current manual replacement method is more troublesome and cannot be replaced in time. Therefore, it cannot meet the existing switchgear use requirements. For this reason, technical personnel in this field have proposed a high-voltage switchgear intelligent control system to solve the problems raised in the above background. Summary of the invention

[0004] The purpose of the present invention is to provide a high-voltage switch cabinet intelligent control system to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] An intelligent control system for a high-voltage switch cabinet, comprising a switch cabinet and a cabinet door movably connected to the switch cabinet; a replacement cavity is provided on the inner wall of the switch cabinet, the replacement cavity is circular, the replacement cavity is connected to a feeding channel and a discharging channel provided in the inner wall of the switch cabinet, the feeding channel is vertically arranged, and the discharging channel is obliquely arranged; a drying port connected to the replacement cavity is provided in the switch cabinet, a discharging port connected to the feeding channel and a cover plate clamped to the discharging port are provided on the switch cabinet, a controller is installed on the outer wall of the switch cabinet, and further comprises;

[0007] A replacement mechanism, which is arranged in the replacement chamber and is used to continuously replace the desiccant at the drying port and discharge the used desiccant;

[0008] A driving mechanism is arranged on the outer wall of the switch cabinet and is used to drive the replacement mechanism.

[0009] As a further solution of the present invention: heat dissipation holes are provided on both sides of the switch cabinet.

[0010] As a further solution of the present invention: a humidity sensor is installed on the inner wall of the switch cabinet.

[0011] As a further solution of the present invention: the replacement mechanism includes a rotating shaft rotatably arranged in the replacement chamber, a rotating block in contact with the inner wall of the replacement chamber is installed on the rotating shaft, and a plurality of storage grooves distributed in an annular shape are provided on the rotating block for storing the desiccant used.

[0012] As a further solution of the present invention: the driving mechanism includes a transmission box installed on the outer wall of the switch cabinet, a first gear is installed at one end of the rotating shaft that passes through the transmission box, a driving shaft is rotatably arranged in the transmission box, a second gear meshing with the first gear is installed on the driving shaft, and a motor connected to the driving shaft is installed on the outer wall of the transmission box.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention installs the switch cabinet at the position where it needs to be placed, and puts the disc-shaped desiccant into the feeding channel from the discharge port in sequence. Under the action of gravity, the desiccant will fall to the bottom of the feeding channel and enter the replacement mechanism. The desiccant entering the replacement mechanism will be rotated to the drying port by the rotation of the replacement mechanism. At this time, the desiccant can absorb moisture in the switch cabinet to prevent moisture from corroding the electrical equipment inside the switch cabinet.

At this time, the replacement mechanism is driven by the driving mechanism to rotate the replacement mechanism, and the replacement mechanism rotates the new desiccant to the drying port, thereby maintaining the drying effect of the desiccant on the switch cabinet. At the same time, the dryer with poor drying effect will rotate to the discharge channel and discharge the switch cabinet from the discharge channel. At the same time, the new desiccant in the feeding channel will enter the replacement mechanism for refilling operation, thereby the desiccant can be replaced in time to ensure the dryness of the switch cabinet and the use effect is better.

DETAILED DESCRIPTION

[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] See also Figure 1-Figure 4 , an intelligent control system for a high-voltage switch cabinet, comprising a switch cabinet 1 and a cabinet door 2 movably connected to the switch cabinet 1, wherein the switch cabinet 1 and the cabinet door 2 are movably connected in various ways, which may be a bearing connection or a latch connection; a replacement cavity 8 is provided on the inner wall of the switch cabinet 1, and the replacement cavity 8 is circular, and the replacement cavity 8 is connected to a feeding channel 7 and a discharge channel 9 provided in the inner wall of the switch cabinet 1, the feeding channel 7 is vertically arranged, and the discharge channel 9 is obliquely arranged, a drying port 4 connected to the replacement cavity 8 is provided in the switch cabinet 1, a discharge port 5 connected to the feeding channel 7 and a cover plate 6 clamped to the discharge port 5 are provided on the switch cabinet 1, and the cover plate 6 is used to seal the discharge port 5, and a controller 13 is installed on the outer wall of the switch cabinet 1, and also includes;

[0021] A replacement mechanism, which is arranged in the replacement chamber 8 and is used to continuously replace the desiccant at the drying port 4 and discharge the used desiccant;

[0022] A driving mechanism is arranged on the outer wall of the switch cabinet 1 and is used to drive the replacement mechanism.

[0023] By installing the switch cabinet 1 at the required position, and by placing the disc-shaped desiccant from the discharge port 5 into the feeding channel 7 in sequence, the desiccant will fall to the bottom of the feeding channel 7 under the action of gravity and enter the replacement mechanism. The desiccant entering the replacement mechanism will be rotated to the drying port 4 by the rotation of the replacement mechanism. At this time, the desiccant can absorb moisture in the switch cabinet 1 to prevent moisture from corroding the electrical equipment inside the switch cabinet 1. When the moisture data in the switch cabinet 1 is detected to be abnormally increased, it indicates that the drying effect of the desiccant is weakened. At this time, the replacement mechanism is driven by the driving mechanism to rotate the replacement mechanism, and the replacement mechanism rotates the new desiccant to the drying port 4, so that the drying effect of the desiccant on the switch cabinet 1 can be maintained. At the same time, the dryer with poor drying effect will rotate to the discharge channel 9 and discharge the switch cabinet 1 from the discharge channel 9. At the same time, the new desiccant in the feeding channel 7 will enter the replacement mechanism for refilling operation, so that the desiccant can be replaced in time to ensure the dryness of the switch cabinet 1 and better use effect.

[0024] In one case of this embodiment, heat dissipation holes 3 are provided on both sides of the switch cabinet 1. The preset heat dissipation holes 3 on both sides of the switch cabinet 1 can increase the air circulation effect in the switch cabinet 1, so that the switch cabinet 1 can be effectively ventilated and dried.

[0025] In one case of the present embodiment, a humidity sensor 19 is installed on the inner wall of the switch cabinet 1. The humidity in the switch cabinet 1 is detected in real time by the humidity sensor 19, and the humidity data is transmitted to the controller 13. When the humidity data detected by the humidity sensor 19 increases abnormally and exceeds the set threshold, it indicates that the drying effect of the desiccant has deteriorated and needs to be replaced. At this time, the controller 13 will send a signal and start the driving mechanism, and the driving mechanism drives the replacement mechanism to realize the replacement of the desiccant.

[0026] In one case of this embodiment, the replacement mechanism includes a rotating shaft 10 rotatably arranged in the replacement chamber 8, and a rotating block 11 is installed on the rotating shaft 10 and is in contact with the inner wall of the replacement chamber 8. The rotating block 11 is provided with a plurality of storage grooves 12 distributed in a ring shape for storing the desiccant to be used. Preferably, in this embodiment, three storage grooves 12 are provided.

[0027] The desiccant falling in the feeding channel 7 will fall into the storage slot 12 of the rotary block 11. When the storage slot 12 rotates to correspond to the drying port 4, the desiccant in the storage slot 12 can dry the switch cabinet 1. When the desiccant needs to be replaced, the driving mechanism drives the rotating shaft 10 to rotate, so that the rotary block 11 rotates. The rotation of the rotary block 11 will rotate the desiccant in the storage slot 12 originally located below the feeding channel 7 to the drying port 4, thereby realizing the replacement of the desiccant in the switch cabinet 1. At the same time, the storage slot 12 storing the desiccant with poor drying effect will rotate to be connected with the discharge channel 9. Under the action of gravity, the desiccant will be discharged along the discharge channel 9, and the desiccant in the feeding channel 7 will fall into the storage slot 12 of the rotary block 11 under the action of gravity, thereby realizing the replenishment.

[0028] In one case of this embodiment, the driving mechanism includes a transmission box 14 installed on the outer wall of the switch cabinet 1, and a first gear 15 is installed at one end of the rotating shaft 10 that penetrates into the transmission box 14. A driving shaft 17 is rotatably arranged in the transmission box 14, and a second gear 16 that meshes with the first gear 15 is installed on the driving shaft 17. A motor 18 connected to the driving shaft 17 is installed on the outer wall of the transmission box 14.

[0029] By starting the motor 18, the driving shaft 17 is driven to rotate, and the driving shaft 17 drives the second gear 16 to rotate. The first gear 15 and the second gear 16 are meshed to drive the first gear 15 to rotate, thereby driving the rotating shaft 10 to rotate, that is, the replacement mechanism can be driven to replace the desiccant.

[0030] The present invention installs the switch cabinet 1 at the required position, and puts the disc-shaped desiccant into the feeding channel 7 from the discharge port 5 in sequence. Under the action of gravity, the desiccant will fall to the bottom of the feeding channel 7 and enter the replacement mechanism. The desiccant entering the replacement mechanism will be rotated to the drying port 4 by the rotation of the replacement mechanism. At this time, the desiccant can absorb moisture in the switch cabinet 1 to prevent moisture from corroding the electrical equipment inside the switch cabinet 1. When it is detected that the moisture data in the switch cabinet 1 is abnormally increased, it indicates that the drying effect of the desiccant is weakened. At this time, the replacement mechanism is driven by the driving mechanism to rotate the replacement mechanism, and the replacement mechanism rotates the new desiccant to the drying port 4, so that the drying effect of the desiccant on the switch cabinet 1 can be maintained. At the same time, the dryer with poor drying effect will rotate to the discharge channel 9 and discharge the switch cabinet 1 from the discharge channel 9. At the same time, the new desiccant in the feeding channel 7 will enter the replacement mechanism for refilling operation, so that the desiccant can be replaced in time to ensure the dryness of the switch cabinet 1 and better use effect.
