Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of anti-moisture structure for substations, specifically an anti-moisture structure for intelligent substations. Background Technology
[0002] A substation is a location in a power system that transforms voltage and current, receives electrical energy, and distributes it. Substations within power plants are step-up substations, whose function is to step up the voltage of the electricity generated by generators and feed it into the high-voltage power grid. The electrical equipment in a substation is divided into primary and secondary equipment. Below is a brief introduction to the main equipment in a substation. Primary equipment refers to equipment that directly produces, transmits, distributes, and uses electrical energy, mainly including transformers, high-voltage circuit breakers, disconnect switches, busbars, surge arresters, capacitors, and reactors. Secondary equipment in a substation refers to equipment that measures, monitors, controls, and protects the operating conditions of the primary equipment and system. It mainly consists of relay protection devices, automatic devices, measurement and control devices, metering devices, automation systems, and DC equipment that provides power to the secondary equipment. Existing prefabricated substations typically require a moisture-proof structure to prevent external moisture from entering the enclosure and damaging the components inside. This moisture-proof structure usually requires a dehumidifier or air circulation fan, and a moisture-proof pad is also needed inside the enclosure wall.
[0003] Patent No. CN202321084162.9 discloses a box-type substation with a moisture-proof structure. By combining the limiting component with the moisture-proof pad, the rollers in the limiting component can be rotated by the drive mechanism, so that the moisture-proof pad can move inside the box wall, which is convenient for assembly and disassembly. At the same time, it can also ensure the stability of the moisture-proof pad during use and can cope with moisture-proof pads of different thicknesses to a certain extent. The moisture-proof pad itself can play a role in moisture protection and sound insulation, reflecting the flexibility of the overall structural design.
[0004] The aforementioned patent discloses a box-type substation with a moisture-proof structure. By using a drive mechanism, the rollers in the limiting assembly can be rotated, allowing the moisture-proof pad to move inside the box wall. The moisture-proof pad can only move slightly on one wall. When the moisture-proof pad is damp, it can only be replaced. No matter where it is moved to on that wall, it will remain damp. Utility Model Content
[0005] The purpose of this utility model is to provide an anti-moisture structure for intelligent substations. The anti-moisture structure for intelligent substations disclosed in this utility model uses a transition roller at the corner of the inner wall of the substation shell to limit the moisture-absorbing sheet to adhere to the inner wall of the substation shell. When the moisture-absorbing sheet is wet, one of the rollers can be rolled up and the other roller can be unrolled to replace the dry moisture-absorbing sheet. The regeneration drying component can dry and regenerate the rolled-up moisture-absorbing sheet, thereby solving the problems mentioned in the background art.
[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-moisture structure for intelligent substations, comprising a substation shell, wherein a first roller and a second roller are respectively mounted on one side of the inner wall of the substation shell via a first mounting shell and a second mounting shell, a first gear and a second gear are respectively locked on the top of the first roller and the second roller, the second gear is meshed with the outer wall of the first gear, the two ends of a moisture-absorbing sheet are respectively wound up on the outer walls of the first roller and the second roller, and the middle part of the moisture-absorbing sheet is limited and adhered to the inner wall of the substation shell by a transition roller at the corner of the inner wall of the substation shell.
[0007] Preferably, transition rollers are rotatably installed at each of the four corners of the inner wall of the substation casing via roller frames.
[0008] Preferably, both the first mounting shell and the second mounting shell have a moisture vent on their upper parts.
[0009] Preferably, the power input end of the second gear is connected to the power output end of the electric motor.
[0010] Preferably, the bottom of the first and second mounting shells are provided with air inlets and the air inlets are connected to a regeneration drying component.
[0011] Preferably, the regeneration drying assembly includes a first mounting shell and a fan connected to the bottom air inlet of the second mounting shell via an air duct, and a heating assembly is installed at the air outlet of the fan.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] The intelligent substation moisture-proof structure disclosed in this utility model uses a transition roller at the corner of the inner wall of the substation shell to limit the moisture-absorbing sheet to adhere to the inner wall of the substation shell. When the moisture-absorbing sheet is wet, one of the rollers can be rolled up and the other unrolled to replace the dry moisture-absorbing sheet. The regeneration drying component can dry and regenerate the rolled-up moisture-absorbing sheet. This solves the problem of the box-type substation with moisture-proof structure disclosed in the above-mentioned patent, which relies on a drive mechanism to drive the rollers in the limiting component to rotate, allowing the moisture-proof pad to move inside the box wall. The moisture-proof pad can only move slightly on one wall, and when the moisture-proof pad is wet, it can only be replaced. No matter where it is moved to on that wall, it will still be wet.

[0019] 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.
[0020] Please see Figures 1-4 The diagram illustrates an intelligent substation anti-moisture structure, comprising a substation housing 1. A first roller 14 and a second roller 15 are respectively mounted on one side of the inner wall of the substation housing 1 via a first mounting shell 8 and a second mounting shell 9. A first gear 5 and a second gear 6 are respectively locked to the top of the first roller 14 and the second roller 15. The outer wall of the first gear 5 is meshed with the second gear 6. The outer walls of the first roller 14 and the second roller 15 respectively wind up both ends of a moisture-absorbing sheet 4. The middle of the moisture-absorbing sheet 4 is limited and adheres to the inner wall of the substation housing 1 by a transition roller 3 at the corner of the inner wall of the substation housing 1. This intelligent substation anti-moisture structure uses the transition roller 3 at the corner of the inner wall of the substation housing 1 to limit the moisture-absorbing sheet 4 to adhere to the inner wall of the substation housing 1. When the moisture-absorbing sheet 4 is damp, a dry moisture-absorbing sheet 4 can be replaced by winding one roller up and unwinding the other. The regeneration drying assembly can dry and regenerate the wound-up moisture-absorbing sheet 4.
[0021] Furthermore, each of the four corners of the inner wall of the substation casing 1 is equipped with a transition roller 3 via a roller frame 2 for easy positioning; furthermore, both the first mounting shell 8 and the second mounting shell 9 have a dehumidification port 10 on their upper parts for easy dehumidification; furthermore, the power input end of the second gear 6 is connected to the power output end of the motor 7 for easy driving; furthermore, the bottom of the first mounting shell 8 and the second mounting shell 9 have an air inlet connected to a regeneration drying component for easy air intake; furthermore, the regeneration drying component includes a fan 11 connected to the bottom air inlet of the first mounting shell 8 and the second mounting shell 9 via a duct 13, and a heating component 12 is installed at the air outlet of the fan 11 for easy blowing out hot air to dry the regenerated moisture-absorbing sheet 4.
[0022] In this solution, during use, the intelligent substation anti-moisture structure disclosed in this utility model uses a transition roller 3 at the corner of the inner wall of the substation shell 1 to limit the moisture-absorbing sheet 4 to adhere to the inner wall of the substation shell 1. When the moisture-absorbing sheet 4 is damp, one of the rollers can be wound up while the other is unwound to replace the dry moisture-absorbing sheet 4. The regeneration drying component can dry and regenerate the wound-up moisture-absorbing sheet 4. When the moisture-absorbing sheet 4 attached to the wall is damp, the external power supply turns on the motor 7 through an external switch and controls the motor 7 to rotate clockwise for a certain period of time. The clockwise rotation of the motor 7 drives the second gear 6 and the second roller 15 to rotate clockwise. The first gear 5, which is meshed with the outer wall of the second gear 6, rotates counterclockwise. The first roller 14 rotates counterclockwise synchronously, and the first roller 14 winds up one end of the moisture-absorbing sheet 4 while the second roller 15 unwinds. At the other end of the moisture-absorbing sheet 4, the damp moisture-absorbing sheet 4 is wound up by the first roller 14, and the dry moisture-absorbing sheet 4 is unwound by the second roller 15. After passing through the transition roller 3 at the corner of the inner wall of the substation housing 1, it is limited and attached to the inner wall of the substation housing 1. At this time, the fan 11 and the heating component 12 are turned on, and hot air is blown into the first mounting shell 8 and the second mounting shell 9 through the air duct 13 to regenerate the dry and damp moisture-absorbing sheet 4. Next, the motor 7 is reversed to unwound the dry moisture-absorbing sheet 4 through the first roller 14 and wound up the damp moisture-absorbing sheet 4 through the second roller 15, so that it can be used repeatedly. The moisture-absorbing sheet 4 is made of a material that is easy to absorb moisture and is tough. It is not easy to break under tension. It can be made of steel wire strung on the back of the rubber base and moisture-absorbing cotton sheet attached to the surface (the motor 7, fan 11 and heating component 12 are all existing products on the market).
