Description

Technical Field

[0001] This utility model relates to the field of high-voltage metering cabinets, specifically an indoor high-voltage metering cabinet. Background Technology

[0002] An indoor high-voltage metering cabinet is a key piece of equipment in power systems used for electricity metering in indoor high-voltage environments. The cabinet is made of metal, providing excellent protection to ensure that internal electrical components are not affected by external interference. It integrates core metering devices such as voltage transformers, current transformers, and an electricity meter. During operation, the voltage and current transformers proportionally convert the high voltage and large current in the high-voltage circuit into low voltage and small current suitable for the electricity meter's measurement, allowing the meter to accurately measure electrical energy. Indoor high-voltage metering cabinets are widely used in high-voltage power supply systems in indoor locations such as factories and shopping malls to accurately measure electricity consumption, providing a reliable basis for electricity settlement and management.

[0003] A search revealed that Chinese patent CN222422824U discloses an indoor high-voltage metering cabinet. This patent describes a design using two placement frames to hold the desiccant, facilitating the complete removal of the desiccant from the holding tank for replacement. This eliminates the need to remove the desiccant piece by piece, avoiding the inconvenience of desiccant replacement. Furthermore, the placement frames are completely within the holding tank, preventing maintenance personnel from bumping into them and causing the desiccant to splash out due to vibration. A protective net prevents the desiccant from splashing out of the holding tank from above. Combined with an operating panel, connecting rods, springs, and two movable rods, this design allows the two placement frames to extend laterally out of the holding tank for easy removal.

[0004] While this solution enables quick removal and placement of the dryer, the internal electrical equipment needs to be installed in a designated location as required. However, the internal mounting plate is fixed by screws, so when adjustments are needed, specialized tools must be used to unscrew, adjust, and then screw it back on. This process is complex, time-consuming, and labor-intensive, resulting in a significant reduction in work efficiency. To solve this technical problem, this utility model proposes an indoor high-voltage metering cabinet. Utility Model Content

[0006] While this solution enables quick removal and placement of the dryer, the internal electrical equipment needs to be installed in a designated location as required. However, the internal mounting plate is fixed by screws, so when adjustments are needed, specialized tools must be used to unscrew, adjust, and then screw it back on. This process is complex, time-consuming, and labor-intensive, resulting in a significant reduction in work efficiency. To solve this technical problem, this utility model proposes an indoor high-voltage metering cabinet.

[0013] Preferably, the cabinet has exhaust vents on both sides, and a dustproof net is fixedly installed inside the exhaust vent. The cabinet is rotatably connected to a switch door.

[0014] (III) Beneficial Effects

[0015] This utility model provides an indoor high-voltage metering cabinet. It has the following beneficial effects:

[0016] (1) The mounting bracket is fixed to the cabinet and has sockets distributed on it. The mounting plate is connected to the mounting bracket by a slider. The slider can slide at the upper limit of the mounting bracket to ensure the smooth movement of the mounting plate. When the position of the mounting plate needs to be adjusted, the second limiting ring is pulled outward, which drives the pin outward. The first limiting ring is pulled by the pin and squeezes the spring on the bracket, so that the pin is pulled out of the socket of the mounting bracket. At this time, the mounting plate can be pushed up and down. When the mounting plate is moved to the appropriate position and its inner hole is aligned with the corresponding socket of the mounting bracket, the second limiting ring is released. The spring rebounds and pushes the first limiting ring, so that the pin passes through the inner hole and inserts into the socket, thus completing the fixing of the mounting plate. The mounting plate has mounting holes for installing equipment. This combination solves the problems of inconvenient fixing of the mounting plate position and poor adaptability in the existing device. It realizes the flexible and quick adjustment of the mounting plate position inside the cabinet, which is convenient for installing different electrical equipment according to actual needs, and improves the cabinet space utilization efficiency and equipment installation convenience.

[0017] (2) The fan is installed inside the ventilated housing. After starting, it promotes the air circulation inside the cabinet. The water tank is filled with water through the water filling pipe. The electric cooling rod is powered on to cool the water in the water tank. The circulation pump starts and pumps the cold water in the water tank into the water pipe. The water pipe is coiled in the fixed frame. When the cold water flows in the water pipe, cold air is generated on the outer wall of the water pipe. The fan blows the cold air into the cabinet, which accelerates the heat dissipation and achieves efficient heat dissipation. This combination solves the problem of low heat dissipation efficiency and easy overheating damage of the existing device. It realizes rapid cooling of the cabinet, maintains the appropriate operating temperature of the equipment, extends the service life of the equipment, ensures the stable and efficient operation of the power equipment, improves the overall performance and reliability of the equipment, and reduces the failure rate caused by overheating.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] Example 1: An indoor high-voltage metering cabinet includes a cabinet body 1. A pair of mounting brackets 2 are fixedly connected inside the cabinet body 1. Each mounting bracket 2 has multiple insertion holes 3 inside. A mounting plate 4 is arranged between the two mounting brackets 2. The mounting plate 4 has multiple mounting holes 11 inside. A slider 5 is fixedly connected to both ends of the mounting plate 4. The slider 5 is slidably connected to the outer wall of the mounting bracket 2. A bracket 6 is fixedly connected to the outer wall of each slider 5. A pin 7 is slidably connected inside the bracket 6. At the same time, an inner hole 10 is opened inside the slider 5. The pin 7 is slidably connected to the inner hole 10 and the insertion hole 3. A limit ring 1 8 is fixedly connected to the middle outer wall of the pin 7. A limit ring 2 12 is fixedly connected to the outer wall of one end of the pin 7. A spring 9 is fixedly connected between the limit ring 1 8 and the bracket 6. At the same time, the spring 9 is sleeved on the outer wall of the pin 7. A switch door 25 is rotatably connected to the outside of the cabinet body 1.

[0026] When installing electrical equipment, first open the switch door 25. If it is necessary to adjust the position of the mounting plate 4 inside the cabinet 1 according to the installation location requirements of the electrical equipment, the following steps can be taken: Pull the limiting ring 2 12 outward, which causes the pin 7 to move outward simultaneously. During the movement of the pin 7, the limiting ring 1 8 will compress the spring 9 fixed on the bracket 6 until the pin 7 is completely pulled out of the socket 3 in the mounting bracket 2. At this time, the mounting plate 4 can be pushed up and down. Since the mounting plate 4 slides at the upper limit of the mounting bracket 2 through the slider 5, it can move smoothly. When the mounting plate 4 moves to the appropriate position and the inner hole 10 on the mounting plate 4 is aligned with the corresponding socket 3 on the mounting bracket 2, release the limiting ring 2 12. At this time, the spring 9 rebounds, pushing the pin 7 in the limiting ring 1 8 so that it passes through the inner hole 10 and is inserted into the socket 3, thereby completing the fixing of the mounting plate 4. Through the coordinated operation of this series of components, the position of the mounting plate 4 can be quickly adjusted, which provides convenience for the subsequent installation of electrical equipment and greatly improves work efficiency.

[0027] Example 2: The difference between this example and Example 1 is that, in this example, a ventilated outer shell 13 is fixedly connected to the lower part of the cabinet 1, and a pair of fixed brackets 14 are fixedly connected to the lower part of the ventilated outer shell 13. A fan 15 is fixedly connected inside each fixed bracket 14. At the same time, a fixed frame 16 is fixedly connected inside the ventilated outer shell 13, and a water pipe 17 is arranged around the inside of the fixed frame 16. A placement plate 18 is fixedly connected to the lower part of the cabinet 1. A water tank 20 is fixedly connected to the top of the placement plate 18. A circulation pump 19 is fixedly connected to the bottom of the water tank 20. One end of the water pipe 17 is fixedly connected to the output end of the circulation pump 19, and the other end of the water pipe 17 passes through the ventilated outer shell 13 and the cabinet 1 and extends into the water tank 20. A water filling pipe 22 is provided on the top of the water tank 20. A pair of electric cooling rods 21 are provided inside the cabinet 1. Exhaust vents 23 are opened on both sides of the cabinet 1, and dustproof nets 24 are fixedly installed inside the exhaust vents 23.

[0028] When heat dissipation is needed inside cabinet 1, the fan 15 on the internal mounting bracket 14 of the ventilated outer shell 13 is first activated. After the fan 15 starts running, air circulation begins inside cabinet 1. Simultaneously, water is injected into the water tank 20, and then the power supply to the electric cooling rod 21 is connected. The electric cooling rod 21 starts, cooling the water in the water tank 20. Next, the circulation pump 19 is activated, delivering the cold water from the water tank 20 to the water pipe 17. The water pipe 17 circulates within the mounting frame 16. As the cold water flows through the pipe, cool air is generated on the outer wall of the water pipe 17. The fan 15 blows this cool air into cabinet 1, accelerating heat dissipation. During this heat dissipation process, hot air is exhausted through the exhaust vent 23. The dust filter 24 is installed at the corresponding position on cabinet 1 to filter the air entering cabinet 1, intercepting impurities and preventing them from entering the cabinet.

[0029] Working principle: When the operator needs to install electrical equipment inside cabinet 1, they first open the switch door 25. Based on the installation location requirements, they adjust the position of the mounting plate 4 inside cabinet 1. Then, they pull outwards, causing the pin 7 to move outwards. The first limiting ring 8 compresses the spring 9 fixed to the bracket 6 until the pin 7 is pulled out of the socket 3 inside the mounting bracket 2. The mounting plate 4 is then pushed up and down, sliding on the mounting bracket 2 via the slider 5. When it reaches the appropriate position and the inner hole 10 aligns with the socket 3, the second limiting ring 12 is released. The spring 9's return pushes the pin 7 inside the first limiting ring 8 through the inner hole 10 and into the socket 3 for fixation, thus facilitating the installation of the electrical equipment on the mounting plate 4. Through their cooperation, the mounting plate 4 can be quickly adjusted, facilitating the subsequent installation of electrical equipment and improving work efficiency. After installation, the fan 15 on the internal fixing frame 14 of the ventilated outer shell 13 is started to dissipate heat from the inside of the cabinet 1. At this time, water is added to the water tank 20, and the electric cooling rod 21 is connected to the power supply to start cooling the water. In conjunction with starting the circulation pump 19, the water is delivered to the water pipe 17, and the water pipe 17 circulates within the fixing frame 16. Cold air is generated outside and blown into the cabinet 1 by the fan 15 for rapid heat dissipation. Hot air is discharged outside through the exhaust vent 23, and the dustproof net 24 protects the cabinet 1 and intercepts impurities. Through their cooperation, a rapid cooling effect is achieved.
