Description

Technical Field

[0001] The invention relates to the technical field of electrical devices, in particular to a high and low voltage complete electrical cabinet for outdoor use and a method thereof. Background Art

[0002] High and low voltage complete electrical cabinets are crucial equipment in the power system. When used in outdoor environments, they need to have a higher level of protection to cope with severe weather and complex environments. They are mainly composed of high voltage switchgear and low voltage switchgear, and can complete the power distribution, control, protection and other functions of the power system.

[0003] The patent with application number CN202210012479.5 discloses a high and low voltage complete electrical cabinet, including a frame, a cover, a rotating shaft, an opening component, a ventilation component, etc. A rotating shaft is rotatably provided on the left front side of the frame, and a cover for closing the frame is provided on the rotating shaft. The cover is in contact with the front side of the frame, and an opening component for opening the cover is provided between the frame and the cover. The first L-shaped connecting rod moves forward to trigger the first contact switch to control the start of the air suction machine, so that the air suction machine quickly discharges the hot air in the frame for heat dissipation, prevents the occurrence of explosion, and has high safety.

[0004] However, in the assembly process of existing electrical cabinets, the way to fix multiple cabinet bodies mainly relies on the combination of bolts and connecting plates. This process not only requires a lot of manual operation, but also the tightening degree of the bolts and the alignment of the connecting plates need to be precisely controlled, resulting in the entire installation process being cumbersome and time-consuming. In addition, when fixing the component placement rack, electrical workers often need to perform a series of complex adjustments and operations to ensure that the placement rack is stable and accurately positioned, which undoubtedly increases the difficulty and labor intensity of the assembly work, and also prolongs the overall installation period of the electrical cabinet.

10. A method for assembling a high and low voltage electrical cabinet for outdoor use, using the high and low voltage electrical cabinet for outdoor use as claimed in any one of claims 1 to 9, characterized in that: The following steps are involved: S1. According to the design requirements of the electrical equipment, the upper and lower ends of a plurality of fixed cabinets (100) are respectively clamped and fixedly connected to the outer side walls of the upper and lower fixed beams (210), and the insertion blocks (312) on the reinforcing strips (311) are ensured to be inserted into the insertion grooves (3112) in the adjacent reinforcing strips (311); S2, the outer cover bracket (230) is fixedly connected to the fixed cabinet (100) and the fixed crossbeam (210) respectively by bolts, and the frame surface protrusion (240) is inserted into the inside of the insertion groove (3112) of the rightmost reinforcing strip (311); S3. According to the design requirements of the electrical components, a plurality of component placement racks (420) are placed in a plurality of storage slots (412) by placing the components in the slots (411) in a regular manner; S4. The operator then twists the insert bar (322) in the leftmost transmission part (320) with a wrench, driving the twisting rods (321) in the transmission parts (320) to rotate simultaneously, thereby causing the worm (323) in the transmission part (320) to rotate; S5, after the worm (323) rotates, it cooperates with the worm wheel (324) to drive the rotating cylinders (325) on both sides to rotate, so that the internal screw rod (326) in the rotating cylinder (325) rotates together, and then the internal screw rod (326) rotates inside the partition plate (314), thereby cooperating with the internal thread groove of the partition plate (314), so that the internal screw rod (326) moves inside the rotating cylinder (325); S6. At this time, the insertion screw (328) rotates together with the inner screw (326) and moves outward, and its end portion cooperates with the thread groove of the insertion block (312) during the rotation process, so that the insertion screw (328) is fixed inside the insertion block (312); S7, while the torsion rod (321) rotates, the end of the connecting rope (444) in the linkage part (440) is continuously wound around the torsion rod (321), so that the connecting rope (444) pulls the sliding plate (441) to move in the internal space of the placement column (410), thereby compressing the pressure spring (442), increasing the elastic potential energy of the pressure spring (442), and thus increasing the force acting on the sliding bracket (430); S8. Afterwards, the operator fixes several electrical components on the outside of several component placement racks (420), and after completing the wiring, the complete set of operations of the electrical cabinet is completed.
