Abstract

The application discloses a power cabinet with a multi-layer insulation structure and relates to the technical field of insulation power cabinets. The ventilation hole on the partition plate is located directly below the ventilation plate through the deep push-pull handle. The push of the handle makes the pressing block on the partition plate extrude the drying switch, so that the heating fan is opened. The external air enters the drying box through the upper ventilation cover, is heated and dried by the heating element, and is diffused into the second cavity from the filter plates on both sides of the drying box. The heated air is diffused into the interior of the power cabinet and the plug-in box through the ventilation plate and the ventilation hole located directly below the ventilation plate, and the interior parts are dried. The moisture-absorbing sponge ball can absorb the water vapor in the power cabinet, and the water vapor absorbed by the moisture-absorbing sponge ball can also be dried through the drying structure. When the service time is too long, the connecting cover is opened, and the moisture-absorbing sponge ball can be replaced.

Description

Technical Field

[0001] This invention relates to the field of insulated power cabinet technology, specifically to a power cabinet with a multi-layer insulation structure. Background Technology

[0002] Electrical switchgear is used to house electrical insulation tools such as insulating gloves, safety helmets, and insulating boots. It is widely used in power plants and can be used for extended periods; however, improper storage can significantly shorten its lifespan. Electrical switchgear (also known as a complete switch or distribution unit) is electrical equipment primarily composed of circuit breakers. It refers to the assembly of relevant high and low voltage electrical appliances (including control, protection, and measuring appliances), busbars, current-carrying conductors, insulators, etc., into a closed or open metal cabinet according to the requirements of the primary electrical wiring diagram. It serves as a device for receiving and distributing electrical energy in a power system and is called a metal switchgear, or simply electrical switchgear. Insulation, a physics term, refers to the use of non-conductive materials to isolate or enclose live conductors to protect against electric shock. Good insulation is the most basic and reliable means to ensure the safe operation of electrical equipment and lines and prevent electric shock accidents. Insulation is generally classified into three categories: gas insulation, liquid insulation, and solid insulation. In practical applications, solid insulation remains the most widely used and reliable insulating material. Under the influence of a strong electric field, insulating materials may break down and lose their insulating properties. Of the three types of insulating materials mentioned above, gaseous insulating materials, once broken down, can recover their inherent electrical insulation properties after the external factor (strong electric field) is removed; however, solid insulating materials, once broken down, irreversibly and completely lose their electrical insulation properties.

[0003] Therefore, the insulation selection for electrical circuits and equipment must be compatible with the voltage level and adapted to the operating environment and conditions to ensure the safe function of the insulation. The insulation resistance requirements for various circuits and equipment under different conditions are roughly as follows: Generally, the insulation resistance of newly installed or overhauled low-voltage circuits should not be less than 100MΩ; for low-voltage circuits and equipment in operation, the insulation resistance should not be less than 3MΩ / V; for equipment and circuits in humid environments, the insulation resistance should not be less than 3MΩ / V; for equipment and circuits in humid environments, the insulation resistance should not be less than 2.5MΩ / V; the insulation resistance in control lines should generally not be less than 1MΩ, while the insulation resistance of high-voltage circuits and equipment should generally not be less than 1000MΩ. However, existing power cabinets have a simple structure and can only perform insulation work. When the device is used for a long time, the moisture generated inside cannot be dried in time, and vibrations are easily generated during movement, which is detrimental to the safety of the device. They also cannot dissipate heat from the internal components, and the messy arrangement of the wiring inside the power cabinet can create unnecessary hidden dangers. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a power cabinet with a multi-layer insulation structure, solving the following technical problems:

[0006] 1. The control of existing multi-layer power cabinets almost entirely relies on manual switches or PCL automatic control. These two control methods can only cut off the power supply to related equipment from an electrical perspective, and cannot effectively isolate the connection between layers and between equipment. Especially for power cabinets with high insulation requirements, isolating the equipment when it is not in use is beneficial for the spatial isolation inside the insulation cabinet.

[0007] 2. The control of drying and heat dissipation equipment in existing multi-layer power cabinets almost entirely relies on manual switches or PCL automatic control. These two control methods can only cut off the power supply to the relevant equipment from an electrical point of view, and cannot effectively isolate the connection between the drying device and the cabinet.

[0008] 3. The existing device can only achieve insulation. When the device is used for a long time, the moisture generated inside cannot be dried in time. It is also prone to vibration during movement, which is not conducive to the safety of the device. It also cannot dissipate heat from the internal parts of the device.

[0026] (III) Beneficial Effects

[0027] This invention provides a power cabinet with a multi-layer insulation structure. It has the following advantages:

[0028] (1) The power cabinet with a multi-layer insulation structure allows the ventilation holes on the partition plate to be positioned directly below the ventilation plate via a deep push handle. Pushing the handle also causes the pressing block at the upper left end of the partition plate to press the drying switch, thus turning on the heating fan. External air enters the drying chamber through the upper ventilation cover, and is then heated and dried by the heating element. The heated air is then dispersed from the filter plates on both sides of the drying chamber into the second cavity, and then through the ventilation plate and the ventilation holes located directly below the ventilation plate into the interior of the power cabinet and the electrical box, drying the internal components. The moisture-absorbing sponge balls in the moisture-proof placement box can absorb moisture from inside the power cabinet, and the moisture absorbed by the sponge balls can also be dried by the drying structure for reuse. When the moisture-absorbing sponge balls are used… If the drying time is too long, the moisture-absorbing sponge balls in the moisture-proof box can be replaced by opening the connecting cover. Conversely, pulling the handle will pull out the partition plate. At this time, the half of the partition plate without ventilation holes is directly below the ventilation plate. This operation blocks the flow holes on the ventilation plate, cutting off the connection between the drying structure and the power cabinet. Pulling out the partition plate connects the bottom of the heat dissipation structure with the inside of the power cabinet. Pulling the handle will also cause the pressing block at the upper left end of the partition plate to press the heat dissipation switch, releasing the drying switch, thereby turning on the cooling fan and turning off the heating fan. Pulling the pull rope will cause the cooling fan to drive the hot air inside the power cabinet out through the louvers. Then, pulling the pull rope again will close the louver window to prevent external dust from entering the inside of the power cabinet.

[0029] (2) The power cabinet with multi-layer insulation structure pulls the telescopic fixing strap. The pulling of the telescopic fixing strap drives the pulling of the connecting buckle, which in turn drives the reset plate to pull towards the fixing block. When the reset plate is subjected to the internal pressure of the fixing block, it retracts inward until it pops out when it matches the first buckle slot. This operation helps to fix the data cables in the cable tray, making them less likely to fall off and firmly fixed to the cable tray. On the one hand, it keeps the inside of the power box clean and dry, and on the other hand, it avoids the safety hazards caused by the messy placement of data cables. The telescopic rod is equipped with a spring, and the right end of the telescopic rod is connected to the right end of the telescopic connecting frame. The fixed connection effectively mitigates collisions during movement due to the extension and retraction of the telescopic rod and the elasticity of the spring. The transparent cabinet door allows a clear view of the internal condition of the electrical box. Pulling the second handle opens the cabinet door, facilitating inspection and maintenance of internal components. Observation windows on the upper and lower surfaces of the cabinet door allow for easy viewing of the cabinet's interior. The first and second insulating pads possess high volume resistivity and electrical breakdown resistance. The first and second sealing strips effectively prevent dust from entering the interior of the electrical cabinet and the electrical box. Attached Figure Description
