Description

Technical Field

[0001] The utility model relates to the technical field of transformer cabinets, in particular to a moisture-proof transformer cabinet. Background Art

[0002] In the prior art, depending on the installation location of the transformer cabinet, in some environments and regions, such as the return of the south wind in the south, the inside of the transformer cabinet should be moisture-proof to prevent condensation from producing water droplets. In the prior art, there are mature solutions to prevent condensation from occurring due to moisture inside the transformer cabinet. Generally, an anti-condensation device is installed. The anti-condensation device can detect the temperature and humidity inside the distribution cabinet. When it is detected that the temperature and humidity exceed the set value, the heating circuit will be started to allow the heating plate to work to control the temperature inside the cabinet to prevent condensation. Some anti-condensation devices also use local low temperatures to condense the water vapor inside the transformer cabinet in advance, thereby achieving the purpose of dehumidification.

[0003] However, in the prior art, this type of refrigeration, moisture-proof and condensation-proof transformer cabinet cannot be isolated from the external environment when using dehumidification. It should be noted that when condensation may occur inside the transformer cabinet, it proves that not only the humidity inside the transformer cabinet is relatively high, but the humidity of the surrounding environment is also relatively high. Because the transformer cabinet in the prior art is not sealed, it cannot be isolated from the external environment for active condensation. As the moisture in the surrounding environment is replenished, it is difficult to quickly reduce the humidity inside the transformer cabinet. Therefore, an improved moisture-proof transformer cabinet is needed to address this problem. Utility Model Content

[0004] The purpose of the utility model is to provide a moisture-proof transformer cabinet to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a moisture-proof substation cabinet, including a substation cabinet, a dehumidification mechanism for making condensation is arranged at the lower end of the substation cabinet, and the dehumidification mechanism includes a collecting bucket, an evaporator, and a compressor assembly. A collecting bucket is fixedly arranged at the lower end of the inside of the substation cabinet, an evaporator is fixedly arranged inside the collecting bucket, and a compressor assembly is fixedly arranged on the outside of the substation cabinet, and the evaporator and the compressor assembly are connected to each other; a heat dissipation slot is arranged at the lower end of the surface of the substation cabinet, a heat dissipation fan is arranged at the upper end of the inside of the substation cabinet, and a sealing mechanism is arranged on one side of the heat dissipation slot and the heat dissipation fan of the substation cabinet. The device adopts evaporator refrigeration and then condenses the moisture inside the substation cabinet to form a water column in advance and stores it in the collecting bucket to achieve the purpose of dehumidification. How the evaporator and the compressor assembly are refrigerated is a common method for freezers and air conditioners in the prior art; therefore, the application document no longer elaborates on the refrigeration principle, and the application document only briefly mentions the key components. In fact, there are also key components such as expansion valves and condensers in the prior art; but they are all included in the compressor assembly of the device and are no longer introduced.

[0006] Preferably, the sealing mechanism includes a first slide groove, a first sealing plate, a second slide groove, and a second sealing plate.

The first sealing plate is movably engaged with a slider inside the first slide groove. The upper end of the substation cabinet is provided with a second slide groove on both sides of the heat dissipation fan. The second slide groove is movably engaged with a second sealing plate. The sealing mechanism can ensure that the device can seal the entire substation cabinet when dehumidification is required to reduce the moisture exchange between the interior of the substation cabinet and the external environment, so that the interior of the substation cabinet can be dried quickly to improve the moisture-proof effect; and condensation dehumidification and heat dissipation requirements will not be carried out at the same time, because during condensation dehumidification, the evaporator is in a refrigeration state, and the internal temperature of the substation cabinet can be controlled within a suitable threshold; and if there is a heat dissipation requirement inside the substation cabinet, condensation will not be found even if the humidity inside the substation cabinet is high.

[0007] Preferably, an electric push rod is fixedly provided on the upper end of the first sealing plate on the surface of the transformer cabinet, and the movable end of the electric push rod is fixedly connected to the first sealing plate. The electric push rod can conveniently push the first sealing plate up and down to seal the heat dissipation slot.

[0008] Preferably, a connecting rod is fixedly provided on the outer surface of the first sealing plate, and a transmission rod is movably provided on the upper end of the connecting rod via a rotating shaft, and the upper end of the transmission rod is movably connected to the second sealing plate via the rotating shaft; a connecting rod assembly can be formed by the connecting rod and the transmission rod, so that when the first sealing plate moves down to seal the heat dissipation groove, the second sealing plate can be automatically driven to move to seal the ventilation position of the heat dissipation fan; thus, a linkage effect is formed, which is convenient for use.

[0009] Preferably, a mounting block is fixedly provided on the outer surface of the transformer cabinet, and the connecting rod is movably sleeved inside the mounting block, and the mounting block can ensure the stability of the connecting rod when it moves up and down.

[0010] Preferably, a solenoid valve is fixedly provided at the lower end of the substation cabinet, and a drain pipe is fixedly provided at the lower end of the solenoid valve, through which water generated by condensation inside the substation cabinet can be discharged; and the solenoid valve can control the conduction of the drain pipe, and the drain pipe will be controlled only when needed, such as after condensation and dehumidification are completed.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] The utility model can seal the entire transformer cabinet when moisture-proofing is required to reduce the moisture exchange between the interior of the transformer cabinet and the external environment, so that the interior of the transformer cabinet can be dried quickly to improve the moisture-proof effect; and after dehumidification is completed, the first sealing plate and the second sealing plate can continue to maintain a sealed state to reduce the external moisture from entering the interior of the transformer cabinet; until there is a need for heat dissipation inside the device, the electric push rod is retracted to release the seal.

[0013] When the utility model is used, a connecting rod assembly can be formed through the connecting rod and the transmission rod, so that when the first sealing plate moves down to seal the heat dissipation notch, the second sealing plate can be automatically driven to move to seal the ventilation part of the heat dissipation fan; thus, a linkage effect is formed, which is convenient for use.

The device adopts the evaporator 3 for cooling and then condenses the moisture inside the transformer cabinet 1 into a water column in advance and stores it in the collecting bucket 2 to achieve the purpose of dehumidification. How the evaporator 3 and the compressor assembly 4 perform cooling is a common method for freezers and air conditioners in the prior art; therefore, the present application document will no longer elaborate on the refrigeration principle. The present application document only briefly mentions the key components. In fact, there are also key components such as expansion valves and condensers in the prior art; but they are all included in the compressor assembly 4 of the present device and will not be introduced again.

[0021] The sealing mechanism includes a first slide groove 7, a first sealing plate 8, a second slide groove 9, and a second sealing plate 10.

[0026] Working principle: When using this device, the device adopts the traditional condensation dehumidification method to condense the moisture inside the transformer cabinet 1 at the lower end of the transformer cabinet 1 which is relatively safe, thus achieving the purpose of dehumidification;

[0027] During dehumidification, the electric push rod can be moved downward; thereby, the first sealing plate 8 can be pushed downward to cover and seal the heat dissipation slot 5; and when the first sealing plate 8 moves downward, the second sealing plate 10 can be blocked on the outer surface of the heat dissipation fan 6 under the action of the connecting rod 12 and the transmission rod 13; in this way, when moisture-proofing is required, the entire substation cabinet can be sealed to reduce the moisture exchange between the interior of the substation cabinet 1 and the external environment, so that the interior of the substation cabinet 1 can be quickly dried to improve the moisture-proof effect; and after dehumidification is completed, the first sealing plate 8 and the second sealing plate 10 can continue to remain sealed to reduce the external moisture from entering the interior of the substation cabinet 1; until there is a need for heat dissipation inside the device, the electric push rod is retracted to release the seal;

[0028] When the device is in use, a connecting rod assembly can be formed through the connecting rod 12 and the transmission rod 13, so that when the first sealing plate 8 moves down to seal the heat dissipation slot 5, the second sealing plate 10 can be automatically driven to move to seal the ventilation area of ​​the heat dissipation fan 6; this forms a linkage effect, which makes it easy to use.
