Description

Technical Field

[0001] This utility model relates to the field of high and low voltage switchgear technology, and in particular to a marine corrosion-resistant and vibration-resistant intelligent high and low voltage switchgear. Background Technology

[0002] In highly corrosive marine environments, the high concentration of salt spray and high humidity water vapor that are suspended in the air all year round can easily cause electrochemical corrosion reactions on the surface of switch cabinets and their internal electrical components, especially forming a conductive film layer on the insulating surface, leading to phenomena such as partial discharge, creepage path growth and breakdown failure, which seriously threaten the operational reliability and lifespan of the equipment.

[0003] Existing protective technologies, such as surface spraying with organic coatings like epoxy and polyurethane, can provide some short-term isolation and protection, but under long-term exposure, they are prone to failure modes such as cracking, aging, and peeling. In particular, under the effects of thermal expansion and contraction and air-cooled air circulation, temperature difference condensation effects can easily occur inside the cabinet, causing water vapor to condense and precipitate in critical parts, carrying free salt particles from the air and depositing them on the surface of the devices, forming a "salt bridge" structure, which exacerbates insulation degradation. Traditional moisture-proof and moisture-absorbing solutions, such as silicone moisture-absorbing bags and color-changing gels, only have passive adsorption capabilities and cannot regulate the dynamic balance of the humid and hot environment inside the cabinet, nor can they handle the deposition of salt ions in the condensate, making it difficult to meet the long-term, high-reliability operation requirements of electrical equipment in marine environments.

[0004] During navigation, ships are constantly subjected to multi-axial, multi-frequency composite vibrations and slow, periodic nonlinear oscillations such as rolling and pitching, which are excited by wind and waves. Under such dynamic conditions, the structural fixing methods of traditional switchgear (such as conventional bolt + washer structures) lack self-locking and dynamic compensation functions. They are prone to creeping and loosening due to low-frequency fatigue vibration and micro-amplitude cyclic displacement, which can lead to misalignment of the cabinet structure, failure of threaded connections, or loosening of internal electrical connections, seriously threatening the stability and safety of the system.

[0005] To address these issues, a marine-grade, corrosion-resistant, and vibration-resistant intelligent high and low voltage switchgear is proposed. Utility Model Content

[0006] In order to overcome the shortcomings of existing technologies and solve the problems that most existing high and low voltage switchgear does not fully consider the needs of the special environment of ships and has deficiencies in corrosion resistance, vibration resistance and ventilation and heat dissipation, this utility model provides a marine corrosion-resistant and vibration-resistant intelligent high and low voltage switchgear.

[0007] This utility model is achieved using the following technical solution:

[0008] A marine-grade corrosion-resistant and vibration-resistant intelligent high and low voltage switchgear includes a housing. The housing includes a front plate, a rear plate, a left side plate, a right side plate, a top plate, and a bottom plate. The left and right side plates are arranged opposite each other, and the top and bottom plates are fixed to their upper and lower ends, respectively. The front plate is hinged to the side of the right side plate, and the rear plate is hinged to the side of the left side plate. The front, rear, left, right, top, and bottom plates are combined to form a rectangular switchgear. A partition is also provided between the left and right side plates, which divides the interior of the switchgear into front and rear areas. Multiple wire grooves are provided on both sides of the partition. The wire grooves are evenly spaced and arranged horizontally in parallel. Vibration isolation brackets are provided between the wire grooves, and electrical modules are installed on the vibration isolation brackets.

[0009] The lower end of the front panel is provided with a front filter window, the upper end of the rear panel is provided with a rear filter window, and the right side panel is provided with multiple anti-vibration ribs arranged in parallel and at equal intervals. A heater is installed on the anti-vibration ribs at the bottom of the right side panel.

[0010] The bottom surface of the base plate is provided with connecting beams, and there are four connecting beams. The connecting beams are fixed around the base plate. The bottom of the connecting beams at the bottom of the left and right side plates is provided with support beams. The support beams are fixedly connected to the connecting beams by bolts.

[0011] An instrument panel is provided on the front panel, and a selector switch is provided below the instrument panel;

[0012] The left side plate is provided with multiple seismic ribs, which are arranged in parallel and at equal intervals. The front plate and the rear plate are provided with reinforcing ribs in the center of their back surfaces.

[0014] The housing is made of 316L stainless steel and the exterior of the housing is coated with a fluorocarbon coating or a Zn-Al plating.

[0015] The present invention has the following advantages over the prior art:

[0016] 1. By incorporating anti-corrosion design into the switchgear housing, which is made of 316L stainless steel and coated with fluorocarbon or Zn-Al coating, the switchgear can effectively resist corrosion in the marine environment, extend its service life, and reduce maintenance costs. Furthermore, the internal structure, including vibration isolation brackets, anti-vibration ribs, and reinforcing ribs, can effectively buffer and absorb vibration energy, reduce the impact of vibration on electrical components, protect the normal operation of electrical components, and improve the reliability of the switchgear.

[0017] 2.

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] The present invention will be further described below with reference to the accompanying drawings.

[0026] like Figures 1 to 5As shown, a marine-grade corrosion-resistant and vibration-resistant intelligent high and low voltage switchgear includes a housing. The housing comprises a front plate 1, a rear plate 2, a left side plate 3, a right side plate 4, a top plate 5, and a bottom plate 9. The left side plate 3 and the right side plate 4 are arranged opposite to each other, and the top plate 5 and the bottom plate 9 are respectively fixed to their upper and lower ends. The front plate 1 is hinged to the side of the right side plate 4, and the rear plate 2 is hinged to the side of the left side plate 3. The front plate 1, rear plate 2, left side plate 3, right side plate 4, top plate 5, and bottom plate 9 are combined to form a rectangular switchgear. A partition is also provided between the left side plate 3 and the right side plate 4, and the partition divides the interior of the switchgear... Divided into front and rear areas, this partitioned design makes the internal layout of the switch cabinet more reasonable, facilitating the classification, installation, and management of electrical components. Multiple wire grooves 7 are provided on both sides of the partition. These wire grooves 7 are evenly spaced and arranged horizontally in parallel. The arrangement of the wire grooves 7 facilitates the organization and laying of wires, making the wiring neater and reducing safety hazards caused by messy wiring. Vibration isolation brackets are provided between the wire grooves 7, and electrical modules are installed on these brackets. The vibration isolation brackets effectively buffer and absorb vibration energy, reducing the impact of vibration on the electrical modules and protecting their normal operation.

[0027] The lower end of the front plate 1 is provided with a front filter vent 12, and the upper end of the rear plate 2 is provided with a rear filter vent 21. The front filter vent 12 and the rear filter vent 21 form an air convection channel, which can accelerate the air circulation inside the switchgear and achieve good ventilation and heat dissipation. At the same time, the filter vents can filter dust and impurities in the air, preventing them from entering the switchgear and affecting the performance of electrical components. The right side plate 4 is provided with multiple anti-vibration ribs 41, which are arranged in parallel and equidistantly. A heater 6 is installed on the anti-vibration ribs 41 at the bottom of the right side plate 4. The anti-vibration ribs 41 can enhance the structural strength of the right side plate 4 and improve its vibration resistance. The heater 6 can be activated when the ship is in a low-temperature environment to provide heat to the inside of the switchgear, achieve real-time dehumidification, and prevent oxidation and sparking of the busbar and contacts.

[0028] The bottom surface of the base plate 9 is provided with connecting beams 10. There are four connecting beams 10. The connecting beams 10 are fixed around the base plate 9. The bottom of the connecting beams 10 at the bottom of the left side plate 3 and the right side plate 4 are provided with support beams 8. The support beams 8 are fixedly connected to the connecting beams 10 by bolts. This structural design makes the bottom of the switch cabinet more stable, can better withstand vibration and weight, and improves the overall stability of the switch cabinet.

[0029] The front panel 1 is equipped with an instrument 13, and a changeover switch 14 is located below the instrument 13. The instrument 13 can display the operating parameters of the switch cabinet in real time, making it convenient for operators to understand the equipment status. The changeover switch 14 is used to switch between different working modes to meet different usage needs.

[0030] The left side plate 3 is provided with multiple anti-seismic ribs 41, which are arranged in parallel and at equal intervals to further enhance the anti-seismic capability of the left side plate 3. The front plate 1 and the rear plate 2 are provided with reinforcing ribs 11 at the center of the back side. The reinforcing ribs 11 can improve the structural strength of the front plate 1 and the rear plate 2 and prevent them from deforming when subjected to external forces.

[0031] The top plate 5 is provided with multiple lifting rings 51. There are four lifting rings 51, which are fixed around the top plate 5. The lifting rings 51 facilitate the hoisting and handling of the switch cabinet and improve the efficiency of installation and transportation.

[0032] The housing is made of 316L stainless steel, and the exterior of the housing is coated with a fluorocarbon coating or a Zn-Al coating. 316L stainless steel has excellent corrosion resistance and can resist the corrosion of metals by salt and moisture in marine environments, thus enabling long-term use in marine environments without easily rusting or corroding. At the same time, the exterior of the housing is coated with a fluorocarbon coating or a Zn-Al coating. The fluorocarbon coating has excellent chemical stability and weather resistance, and its dense molecular structure can effectively block the penetration of corrosive substances. The Zn-Al coating, through the cathodic protection principle of sacrificial anode, will preferentially oxidize when the coating is corroded, thereby protecting the underlying stainless steel from corrosion, further enhancing the corrosion resistance of the housing and extending the service life of the switchgear.

[0033] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
