Technical Field

[0001] This utility model relates to the field of gas-filled cabinet technology, specifically a compact gas-filled cabinet. Background Technology

[0002] Gas-insulated switchgear is a new generation of switchgear. The main switch can be either a permanent magnet vacuum circuit breaker or a spring-mechanism vacuum circuit breaker. The entire cabinet combines air insulation with sulfur hexafluoride (SF6) gas compartments, making it both compact and expandable. It is suitable for power distribution automation. Compact gas-insulated switchgear is a type of high-voltage switchgear that uses gas (usually SF6) as the insulating medium, sealed within a metal housing. This design gives the gas-insulated switchgear the characteristics of full insulation and full sealing, providing a highly reliable and safe power distribution solution within a small space. Due to its small size, small footprint, flexible installation, and easy maintenance, compact gas-insulated switchgear has been widely used and favored in the context of increasingly stringent requirements for urban power grid construction and power supply reliability.

[0003] For example, the utility model disclosed in CN204517206U is a compact internally expandable gas-insulated cabinet. It has a compact structure, a small space-consuming busbar connection structure, good concealment, reliable and convenient connection between adjacent cabinets, and a simple and reliable lifting structure. This utility model includes a cabinet body, with a functional panel on the front. Its features include: symmetrically arranged curved plates on the left and right sides of the top of the cabinet, each curved plate having an L-shaped cross-section and comprising a horizontal plate and a vertical plate; the horizontal plate connects to the top of the cabinet, and the vertical plate has through bolt holes and lifting holes; there are two through bolt holes, located in the middle of the vertical plate, with the symmetrical bolt holes on the two curved plates corresponding to each other; there are also two lifting holes, symmetrically located near the ends of the vertical plates, with the lifting holes on the two curved plates corresponding to each other; a busbar connection hole for installing a connector is provided on the side of the cabinet near the top; the functional panel of the cabinet is equipped with an outgoing cable connector assembly and a cable connector.

[0004] However, if the compact gas cabinet is used for too long, the gas inside the cabinet is prone to leakage, making it difficult for staff to detect the problem in time and affecting the efficiency of subsequent work. In addition, when the gas cabinet is used for a long time, the internal parts of the gas cabinet are prone to generating heat, causing the internal temperature of the gas cabinet to overheat and affecting its use. Therefore, a compact gas cabinet is proposed to address the above problems. Utility Model Content

Detailed Implementation

[0022] 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 scope of protection of the present utility model.

[0023] like Figures 1 to 4 As shown, this utility model provides a compact gas-insulated cabinet, including a cabinet body 1. A cavity is opened on one side of the front of the cabinet body 1. Electronic components 2 are installed inside the cavity. Gas leak prevention components 3 are fixedly installed on both sides of the cavity. Gas leak prevention components 3 include gas detectors 31. Gas detectors 31 are fixedly installed on the inner side of the cavity. The entire cabinet body 1 adopts a combination of air insulation and sulfur hexafluoride gas compartment, which is both compact and expandable, and is suitable for power distribution automation. Therefore, the gas detector 31 here is a sulfur hexafluoride detector, model LB-MD4X. Alarms 32 are provided on both sides of the front of the gas detector 31. A power cord 33 is electrically connected to one side of the gas detector 31.

[0024] When personnel use the compact gas cabinet, if an accidental gas leak occurs inside cabinet 1, the gas detector 31 can detect the gas emitted from inside cabinet 1. The gas detector 31 then transmits the detected leaked gas to the data conversion module 4, causing the alarm 32 to sound an alarm, thus quickly alerting personnel to the gas leak. Furthermore, during the use of cabinet 1, the ventilation plate 6 can exchange the air inside and outside the cabinet 1, thereby connecting the power supply to the cooling fan 72. This allows the cooling fan 72 to accelerate the air convection between the ventilation plate 6 and the outside air, thereby achieving the function of cooling cabinet 1.

[0025] like Figures 1 to 4 As shown, a data conversion module 4 is fixedly installed in the middle of the bottom wall of the cavity. One end of the power cord 33 is electrically connected to the data receiving end of the data conversion module 4. A display screen 8 is electrically connected to the front of the data conversion module 4.

[0026] With the configuration of the data conversion module 4 and the display screen 8, when the gas detector 31 detects leaked gas, its display screen 8 can display the leaked gas data, thereby facilitating personnel to observe the effects of the leaked gas.

[0027] like Figures 1 to 4 As shown, screws 5 are threadedly connected to both sides of the cabinet 1. A ventilated plate 6 is threadedly connected to the surface of the screws 5. A heat dissipation component 7 is provided on the front of the ventilated plate 6. The heat dissipation component 7 includes a ventilated grille 71. A ventilated grille 71 is provided on the other side of the front of the ventilated plate 6. A cooling fan 72 is embedded on the other side of the ventilated grille 71. A dustproof net is embedded in the inner wall of the ventilated grille 71. A battery block is installed inside the cooling fan 72.

[0028] With the setting of heat dissipation component 7, during the use of cabinet 1, its ventilation plate 6 and ventilation grille 71 work together to allow the air inside cabinet 1 to be exchanged with the outside air, so that the air forms convection, thereby improving the heat dissipation of cabinet 1.

[0029] like Figures 1 to 4 As shown, a baffle 9 is snapped onto the edge of the front of the cavity, and handles 10 are fixedly installed on both sides of the front of the baffle 9. A maintenance plate 11 is provided on the back of the display screen 8, and a waterproof membrane is attached to the outer surface of the maintenance plate 11.

[0030] The baffle 9 is designed to prevent foreign objects from entering the cavity.

[0031] like Figures 1 to 4 As shown, a heat dissipation plate 12 is attached to the other side of the front of the cabinet 1, and a ventilation groove is embedded on the front of the heat dissipation plate 12.

[0032] The heat dissipation plate 12 further enhances the heat dissipation of the cabinet 1.

[0033] The working principle and usage process of this utility model are as follows: When personnel use the compact gas cabinet, if an accidental gas leak occurs inside the cabinet 1, the gas detector 31 can detect the gas emitted from inside the cabinet 1. Subsequently, the gas detector 31 can transmit the detected leaked gas to the data conversion module 4, causing the alarm 32 to sound an alarm, thus quickly alerting personnel to the gas leak. Furthermore, during the use of the cabinet 1, the ventilation plate 6 can exchange the air inside the cabinet 1 with the outside air, thereby connecting the power supply to the cooling fan 72. This allows the cooling fan 72 to accelerate the air convection between the ventilation plate 6 and the outside air, thereby achieving the function of cooling the cabinet 1.
