Description

Technical Field

[0001] The utility model relates to the field of electric power engineering, in particular to an environmentally friendly electric power inflatable cabinet. Background Art

[0002] An electric power inflatable cabinet is a device used in power systems, primarily for protecting and controlling electrical equipment. It is typically used in high-voltage transmission and distribution systems to provide protection, control, and monitoring for electrical equipment. An electric power inflatable cabinet typically consists of a metal casing containing electrical equipment. The casing is typically made of a material with good protective properties to protect the equipment from environmental influences and mechanical damage. The electrical equipment within, including circuit breakers, disconnectors, and relays, controls the current, voltage, and fault protection functions of the power system.

[0003] However, conventional electric gas cabinets lack the ability to recycle sulfur hexafluoride (SF6), a potent greenhouse gas with a much higher greenhouse effect potential than carbon dioxide. If these systems cannot reuse SF6, emissions during equipment maintenance, replacement, or decommissioning will negatively impact the environment and exacerbate global warming.

[0004] Therefore, the present invention provides an environmentally friendly electric inflatable cabinet to solve the problems raised in the above background technology. Utility Model Content

[0005] The purpose of the present utility model is to solve the shortcomings of the existing technology and propose an environmentally friendly electric gas filling cabinet. The present utility model can recycle and reuse sulfur hexafluoride gas. As a high-quality insulating medium, sulfur hexafluoride gas plays an important role in electrical equipment. The reuse of sulfur hexafluoride gas can avoid waste of resources and improve resource utilization efficiency. In addition, there is no need to frequently handle sulfur hexafluoride gas during maintenance, which simplifies the maintenance process and improves maintenance efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an environmentally friendly electric inflatable cabinet, comprising a shell, wherein the shell is fixedly provided with a partition at the lower end, two cable troughs are fixedly provided on both sides of the interior of the shell, the outer ends of the two cable troughs pass through the partition and lead to the top of the shell, four card slots are fixedly provided on opposite sides of the two cable troughs, and the upper ends of the three card slots located at the upper end of the partition are clamped with electrical components, the upper end of the shell is provided with a mounting slot, and the upper end of the mounting slot is fixedly provided with an exhaust mechanism, and the exhaust mechanism includes a vacuum pump, a No. 1 filter tube is fixedly provided at the output end of the vacuum pump, a silicone sheet is spirally provided at the inner end of the No. 1 filter tube, a connecting pipe is fixedly connected to the outlet of the No. 1 filter tube, a connecting block is threadedly sleeved on the outer end of the connecting pipe, a No. 2 filter tube is fixedly provided at the other end of the connecting pipe, an activated carbon layer is fixedly provided at the inner end of the No. 2 filter tube, and a sulfur hexafluoride gas tank is fixedly provided at the output end of the No. 2 filter tube;

[0007] Through the above technical solution, when opening the cabinet door, you only need to drag it backwards, and the spring will drive the No. 1 connecting rod and the No. 2 connecting rod to move, thereby opening the cabinet door and supporting the cabinet door. When recovering sulfur hexafluoride gas, turn on the vacuum pump of the exhaust mechanism to suck in the air inside the electric inflation cabinet. After entering, the air will first pass through the No. 1 filter tube. The silicone sheet in the tube will filter the tiny particles and impurities suspended in the sulfur hexafluoride gas. Then the sulfur hexafluoride gas enters the No. 2 filter tube through the connecting tube. The internal activated carbon layer can effectively remove impurities and pollutants in the sulfur hexafluoride gas. Finally, the sulfur hexafluoride gas re-enters the gas tank.

[0008] Furthermore, a cabinet door is rotatably provided on one side of the outer end of the shell, and an observation window is provided near the upper end of the cabinet door;

[0009] Through this technical solution, the cabinet door provides a physical barrier, preventing unauthorized access to internal equipment and reducing the risk of electric shock or other safety incidents. Through the observation window, operators can view the operating status of internal equipment, such as indicator lights and instrument readings, without opening the cabinet door.

[0010] Furthermore, two No. 1 connecting rods are hingedly provided on one side of the outer end of the housing, and springs are provided at the other ends of the two No. 1 connecting rods;

[0011] Through the above technical solution, the spring can ensure that the shell can fit smoothly when the cabinet door is closed, avoiding looseness or instability caused by vibration or external force.

[0012] Furthermore, a second connecting rod is rotatably provided at the other end of the two springs, and the other end of the second connecting rod is hingedly provided at the other side of the cabinet door;

[0013] Through the above technical solution, when the cabinet door is closed, the No. 2 connecting rod is hingedly arranged on the cabinet door and the spring and the No. 2 connecting rod are rotated to seal the door gap, thereby preventing sulfur hexafluoride gas from diffusing through the door gap. The force of the spring is used to firmly press the door body against the electric inflatable cabinet to form a sealed state, thereby effectively preventing sulfur hexafluoride gas from escaping from the door gap.

[0014] Furthermore, the spring is arranged on one side of the cabinet door, and a solar panel is fixedly arranged on the upper end of the shell;

[0015] With the above technical solution, after the cabinet door is closed, the spring will stretch at the outer end of the cabinet door, thereby applying a certain amount of pressure when closing the cabinet door, ensuring that the cabinet door can be closed firmly and providing good sealing performance. By installing a solar panel, solar energy can be used to power the exhaust mechanism, improving the energy-saving and environmental protection performance of this new model.

[0016] Furthermore, a wire inlet is provided at the lower end of the two wire troughs;

[0017] Through the above technical solution, there is a wire inlet at the lower end of the cable trough, and the wires can be more conveniently introduced into the electric inflatable cabinet. At the same time, the cables can be arranged more neatly inside the cable trough, which improves the aesthetics and practicality of the device.

[0018] Furthermore, the connection block is threadedly provided at the front end of the housing;

[0019] Through the above technical solution, the connecting block can make it easier to unscrew the connecting pipe from the outer end, which can reduce maintenance time when the connecting pipe needs to be replaced.

[0020] The utility model has the following beneficial effects:

[0021] 1. The utility model proposes an environmentally friendly electric gas filling cabinet, which can recycle and reuse sulfur hexafluoride gas. As a high-quality insulating medium, sulfur hexafluoride gas plays an important role in electrical equipment. The reuse of sulfur hexafluoride gas can avoid waste of resources and improve resource utilization efficiency. In addition, there is no need to frequently handle sulfur hexafluoride gas during maintenance, which simplifies the maintenance process and improves maintenance efficiency.
