Description

Technical Field

[0001] This utility model relates to an electrical device, specifically to a gas-filled cabinet with a modular structure. Background Technology

[0002] Modular gas-insulated switchgear uses SF6 gas as the insulating medium, sealing high-voltage components such as busbars, circuit breakers, and load switches in independent gas chambers to form a fully insulated and enclosed structure. This enables the switching and protection of the power system. The modular design improves operation and maintenance efficiency and adapts to harsh environments, such as humid, salt spray, and high-altitude environments. It is also suitable for substations, subways, offshore wind power, and other scenarios. SF6 gas provides insulation and arc-extinguishing capabilities. The modular design allows each functional unit, including busbars and switches, to operate independently and supports live-line replacement. The operating mechanism controls the opening and closing of circuit breakers, and interlocking devices ensure operational safety. Its compact structure and long lifespan balance reliability and economy, meeting the needs of power distribution automation.

[0003] In the prior art: 201721862726.1 Modular Assembled Gas Cabinet Cabinet, a modular assembled gas cabinet cabinet includes an inflatable compartment, the bottom of which is provided with a base support. One side of the inflatable compartment is provided with a pressure relief chamber, and the other side is provided with a mechanism chamber. The top of the mechanism chamber is provided with a secondary instrument chamber. The top of the assembled mechanism chamber and secondary instrument chamber is higher than the top surface of the pressure relief chamber, and the top surface of the pressure relief chamber is higher than the top surface of the inflatable compartment. The top plate of the main busbar chamber is horizontally installed between the top side wall of the pressure relief chamber and the side wall of the secondary instrument chamber, forming the main busbar chamber together with the upper surface of the inflatable compartment, the upper part of the side wall of the pressure relief chamber, and the side wall of the secondary instrument chamber. The gas cabinet cabinet composed of the pressure relief chamber, mechanism chamber, secondary instrument chamber, and inflatable compartment is provided with outer protective plates on both the front and rear sides. The pressure relief chamber, mechanism chamber, secondary instrument chamber, and outer protective plates are all assembled from sheet metal parts.

[0004] In the existing technology, the sheet metal parts of the gas-insulated switchgear can be prefabricated, which makes the assembly of the gas-insulated switchgear simpler. However, there is also the problem that it is inconvenient to fill the gas-insulated switchgear with insulating medium. Utility Model Content

[0005] To overcome the inconvenience of filling insulating media in existing technologies, this utility model provides a gas-filled cabinet with a modular structure.

[0006] This utility model is achieved using the following technical solution: a modular gas-filled cabinet, comprising a cabinet body, which is divided into a front cabinet body and a rear cabinet body. Assembly spaces are provided within both the front and rear cabinet bodies. An assembly component is provided within the front cabinet body; this assembly component is an assembly module for assembling electrical components. A bottom assembly plate is provided on the assembly module, and assembly holes are provided on the bottom assembly plate. An inflation component, which is an inflation port, is provided on one side of the inflation port. This gas transmission component is a transmission pipe. A side assembly component is provided between the front and rear cabinet bodies.

[0007] The side assembly component is a side hollow bracket, which is located on one side of the rear cabinet, and a side assembly tube adapted to the side hollow bracket is provided on one side of the front cabinet.

[0008] The top of the front cabinet is equipped with a switch module air box, and the switch module air box is equipped with a display module, which is an electronic display screen.

[0009] The rear cabinet is equipped with a partition, and the rear cabinet is equipped with a shelf, on which the partition is placed.

[0010] The rear cabinet is provided with locking plates on both sides, and locking holes are provided on the locking plates. Locking bolts for further assembly of the rear cabinet are provided in the locking holes.

[0011] The rear cabinet has a back support on one side, and the back support has an assembly gap. The back support of the quick search is equipped with a horizontal small support.

[0012] The front cabinet is equipped with a cable routing component, which is a cable routing channel, and the cable routing channel is provided with cable routing space.

[0013] Compared to existing technologies, the gas-insulated cabinet is equipped with a front cabinet and a rear cabinet, which allows for a more complete internal assembly volume. The front cabinet has a bottom assembly plate with standardized assembly holes, which greatly improves the flexibility and efficiency of electrical component installation. The rear cabinet integrates the inflation port, transmission pipes, and removable baffles, which allows for further assembly of electrical module components using the bottom assembly plate.

[0014] The reinforced structure, combining locking bolts and horizontal small brackets, ensures reliable gas sealing and cabinet stability. It provides buffering and assembly space and clearance when assembling the gas cabinet with the wall. The gas cabinet is equipped with side hollow brackets and side assembly tubes, which work together to allow for further assembly and fixation of the gas cabinet. Combined with cable trays and electronic displays, the cable trays facilitate cable routing, making wiring more convenient. Attached Figure Description
