Description

Technical Field

[0001] The utility model relates to the technical field of high and low voltage cabinets, in particular to a high and low voltage cabinet with an extended structure. Background Art

[0002] As the name implies, high and low voltage distribution cabinets are distribution equipment used for power distribution, control, metering and cable connection in the power supply system. Generally, power supply bureaus and substations use high voltage switch cabinets, which are then stepped down by transformers and led out to low voltage distribution cabinets. The low voltage distribution cabinets are then led to the distribution boards, control boxes and switch boxes of various power users. The equipment in the distribution device is a combination of switches, circuit breakers, fuses, buttons, indicator lights, meters, wires and other protective devices that are assembled into one to meet the design functional requirements.

[0003] At present, the storage space of the existing high and low voltage cabinets is fixed. When the staff repairs or inspects the interior, it is not convenient to clearly check the components inside the cabinet. In addition, due to the narrow space, the component lines are densely distributed when arranging the wiring, which makes internal maintenance more cumbersome. Utility Model Content

[0006] Preferably, the connection groove is symmetrically provided with limiting grooves inside, and the limiting groove is slidably connected inside with a limiting block welded to the connection plate.

[0007] Preferably, a guide groove is provided at the top of the mounting seat, a slide groove is provided inside the guide groove, and a sliding block is slidably connected inside the slide groove and welded to the fixing block.

[0008] Preferably, an air inlet is opened on one side of the interior of the first cabinet, a filter is welded and connected to the interior of the air inlet, and a fan is installed on one side of the first cabinet close to the air inlet.

[0009] Preferably, outer surfaces of the second cabinet and the first cabinet are both welded with support blocks, and a cavity is provided inside the support blocks.

[0010] Preferably, a positioning rod is slidably connected inside the cavity, and a tension spring is welded between the positioning rod and the cavity.

[0011] Preferably, an air outlet is provided inside one side of the second cabinet, the second cabinet and the outer surface of the first cabinet are connected with a clamping plate via a hinge seat, and one end of the second cabinet is rotatably connected with a telescopic door.

[0012] In summary, the utility model mainly has the following beneficial effects:

[0013] 1. The storage space of the existing high and low voltage cabinets is limited. When maintaining the interior, it is impossible to clearly observe all the electrical appliances. The utility model is provided with a fixed shaft, a motor, a gear, a rack, a fixed block, a first cabinet, a second cabinet and a connecting plate. The first cabinet and the second cabinet form a sliding structure through the connecting plate and the connecting groove. The motor is started, and the motor drives the fixed shaft and the gear to rotate. The gear can drive the rack and the first cabinet to move, so that the first cabinet drives the connecting plate to move inside the second cabinet, so that the high and low voltage cabinets are extended, thereby achieving the purpose of facilitating the expansion of the internal space of the high and low voltage cabinets;

[0014] 2. The interior of the existing high and low voltage cabinets is prone to moisture under long-term ventilation. The utility model uses the filter screen, fan, support block, cavity, positioning rod, tension spring, air outlet and card plate to pull the positioning rod upward, rotate the card plate to move downward with the hinge seat as the axis, and then start the fan. The fan will pass air into the cabinet, and the air inside the cabinet will be discharged through the air outlet. After the ventilation is completed, the fan is turned off, the positioning rod is loosened, and the card plate is rotated to move upward with the hinge seat as the axis. The air outlet is closed to prevent moisture from appearing inside the cabinet. BRIEF DESCRIPTION OF THE DRAWINGS
