Description

Technical Field

[0002] High-voltage switchgear is a complete set of power distribution equipment used in power systems to receive and distribute high-voltage electrical energy. It is typically used in power transmission and distribution systems with voltage levels of 10kV and above. Its core function is to control, protect, meter, and monitor high-voltage circuits. Internally, it contains key components such as circuit breakers, disconnect switches, instrument transformers, and surge arresters. The cabinet structure integrates and protects electrical equipment. High-voltage switchgear features good insulation performance, safe operation, and a small footprint. It is widely used in substations, factories, high-rise buildings, and other locations, effectively ensuring the stable operation of high-voltage power grids. When overload or short-circuit faults occur, it can quickly cut off the power supply to prevent the accident from escalating. Current high-voltage switchgear has shortcomings in automatic dehumidification, which can lead to damage to internal electrical components, thus requiring improvement. Utility Model Content

[0051] Reference Figures 1 to 5 The present invention provides a further description of an embodiment of an automatic dehumidification high-voltage cabinet.

[0052] An automatic dehumidification high-pressure cabinet includes an outer shell 1 and a sealed door 2, the sealed door 2 being disposed on the outer shell 1. It also includes two ventilation mechanisms, both disposed on the outer shell 1, for ventilation operation. A dehumidification mechanism, disposed inside the outer shell 1, is used for dehumidification operation. The dehumidification mechanism includes: a humidity sensor 3, disposed on and fixedly connected to the outer shell 1; a filter plate 4, disposed on and fixedly connected to the outer shell 1; an isolation plate 5, disposed inside the outer shell 1 and fixedly connected to the outer shell 1; an evaporator 6, disposed on and fixedly connected to the isolation plate 5; a condenser 7, disposed on and fixedly connected to the isolation plate 5; a first motor 8, disposed inside the outer shell 1, for providing power; fan blades 11, disposed at and fixedly connected to the output end of the first motor 8; and two circulation tanks 10, both disposed inside the outer shell 1, for gas flow.

[0053] refer to Figure 1 and Figure 5 In a preferred embodiment, the dehumidification mechanism further includes: a mounting part disposed on the outer casing 1 for fixing components; and a connecting part disposed inside the outer casing 1 for gas circulation.

[0054] refer to Figure 4 and Figure 5 In a preferred embodiment, the mounting part includes: a protective cylinder 9 disposed inside the housing 1 for protecting the first motor 8; and two mounting plates 12 disposed on the housing 1 and fixedly connected to the housing 1.

[0055] With this configuration, the fan blade 11 is rotatably connected to the mounting plate 12, and the circulation tank 10 can discharge the heated air back into the device, thus achieving cyclic operation.

[0056] refer to Figure 2 and Figure 4 In a preferred embodiment, the connection part includes: a first connecting pipe 13, disposed on the evaporator 6, for use with the compressor of the outer casing 1; and a second connecting pipe 14, disposed on the evaporator 6, for use with liquid discharge.

[0057] refer to Figure 1 and Figure 3 In a preferred embodiment, the ventilation mechanism includes: a drive unit disposed within the housing 1 for providing power; and a ventilation unit disposed on the drive unit for ventilation operation.

[0058] refer to Figure 3In a preferred embodiment, the drive unit includes: a second motor 15, which is disposed inside the housing 1 and fixedly connected to the housing 1; a plurality of gears 16, which are disposed inside the housing 1 and rotatably connected to the housing 1; and a rack 17, which is disposed inside the housing 1 and slidably connected to the housing 1.

[0059] Referring to the figure, in a preferred embodiment, the ventilation section includes: a ventilation port 20 disposed on the housing 1 for ventilation operation; a plurality of rotating shafts 18 disposed on and fixedly connected to the gear 16; and a plurality of sealing members 19 disposed on and fixedly connected to the rotating shafts 18.

[0060] With this configuration, gear 16 and rack 17 can mesh, and one of gears 16 is fixedly connected to the output end of the second motor 15, and drives the other gears 16 to rotate through rack 17; and during dehumidification, the amount of outside air entering the device is reduced, allowing the air inside the device to circulate and dehumidify, thereby improving dehumidification efficiency.

[0061] This device, with its ventilation mechanism, ensures proper ventilation and heat dissipation. The size of the ventilation opening 20 can be adjusted flexibly to effectively dehumidify the device. The dehumidification mechanism continuously monitors the internal humidity and works in conjunction with the ventilation mechanism to improve dehumidification efficiency, thus effectively protecting the internal electrical components.

[0062] Working principle: When the humidity sensor 3 detects high humidity inside the device, the second motor 15 first drives the gear 16 to rotate, which in turn drives the other gears 16 to rotate synchronously through the rack 17. This, in turn, drives the seal 19 to rotate through the rotating shaft 18, causing the seal 19 to close the vent 20 and reduce the inflow of outside air into the device. Then, the dehumidification mechanism starts working. The first motor 8 drives the fan blades 11 to quickly pass the humid air inside the device through the filter plate 4 into the evaporator 6. The evaporator 6 condenses the water vapor in the air into liquid water at a low temperature and discharges it through the second connecting pipe 14. Then, the dry air is heated by the condenser 7 and discharged into the circulation tank 10. It then returns to the inside of the device through the circulation tank 10 for multiple cycles until the humidity sensor 3 returns to the normal value. The dehumidification mechanism stops working, and the second motor 15 rotates in the opposite direction, which drives the rotating shaft 18 and the seal 19 to rotate through the gear 16, causing the seal 19 to open and allow ventilation.

[0063] The above description of the embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
