Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a seismic-resistant high and low voltage switch cabinet. Background Art

[0002] High and low voltage switchgear is equipment that connects high-voltage or low-voltage cables. Generally, power supply bureaus and substations use high-voltage cabinets, which are then stepped down by transformers and then transferred to low-voltage cabinets. The low-voltage cabinets are then transferred to distribution boxes for various power users. Inside, there are nothing more than some protective devices such as switches and circuit breakers assembled into one electrical device. When high and low voltage switchgear are arranged in locations prone to vibration, they need to be seismically designed. Existing seismic designs are usually aimed at the overall seismic resistance of the switchgear. For example, the patent with announcement number CN213125306U discloses a seismic structure for low-voltage switchgear, wherein longitudinal seismic support rods are installed on the inner sides of the upper support arms and the lower support arms, and seismic supports are installed at the lower ends of the longitudinal seismic support rods. A shock-absorbing groove is provided inside the seismic support, and a shock-absorbing spring is installed inside the shock-absorbing groove. The seismic resistance effect is improved by arranging a shock-absorbing spring on the outside of the switchgear. However, the switchgear as a whole is relatively heavy, and the spring is located on the outside, which is easily damaged and difficult to maintain. Utility Model Content

[0016] The essential features and advantages of the present invention are further described below with reference to examples, but the present invention is not limited to the examples listed.

[0017] like Figures 1 to 4As shown, a seismic-resistant high- and low-voltage switchgear cabinet according to this embodiment includes a mounting portion 1 and a sliding assembly 2. The mounting portion 1 is mounted on the sliding assembly 2 and is used to mount electrical components, particularly those with poor seismic resistance, which can be centrally arranged on a mounting plate. The mounting portion 1 can slide through the sliding assembly 2, which is mounted in the switchgear cabinet. A seismic-resistant assembly 3 is disposed between the mounting portion 1 and the sliding assembly 2 to reduce the transmission of switchgear vibration to the mounting portion 1. The seismic-resistant assembly 3 includes a cover 31, an upper cover 32, a base 33, a spring 34, and a connecting rod 35. The cover 31 is mounted on the sliding assembly 2 and defines a receiving chamber 311. The bottom of the cover 31 has a bent portion 312, with a notch 313 between the two bent portions 312. The upper cover 32 and base 33 are located within the receiving chamber 311. The spring 34 is disposed between the upper cover 32 and base 33, and the base 33 is disposed on the bent portion 312. The base 33 has a mounting hole 331, in which an elastic member 36 is provided. One end of the connecting rod 35 is connected to the mounting portion 1, and the other end passes through the notch 313, the elastic member 36, the spring 34, and the upper cover 32 and is locked by a locking member 37. The locking member 37 is located above the upper cover 32. The connecting rod 35 can be a screw, and the locking member 37 can be a nut. In the above technical solution, the position of the mounting plate 1 can be adjusted by the sliding assembly 2, and the anti-seismic assembly 3 is suspended below the sliding assembly 2. When the switch cabinet vibrates, the spring between the upper cover 32 and the base 33 can reduce the impact force on the mounting plate, thereby protecting the electrical components on the mounting plate. The upper cover and the base are made of metal, which makes them more durable. The above technical solution can facilitate the rapid assembly of the anti-seismic assembly and facilitate assembly; at the same time, it can protect important electrical components.

[0018] In this embodiment, the upper cover 32 is provided with a first receiving groove 321, and the base 33 is provided with a second receiving groove 332. The ends of the spring 34 are respectively disposed in the first and second receiving grooves, which facilitate the positioning of the spring. A first protrusion 322 is provided within the first receiving groove 321, with multiple first protrusions 322 spaced apart. A second protrusion 333 is provided within the second receiving groove 332, with multiple second protrusions 333 spaced apart. The first and second protrusions are secured to the spring 34, thereby securing the spring in place. The outer wall of the elastic member 36 is provided with an annular groove 361, which is secured within the mounting hole 331 of the base 33, facilitating the snap-on installation of the elastic member 36. The elastic member 36 can be made of an elastic material such as rubber. A through hole 313 is provided at the top of the cover 31, and the sliding assembly 2 is connected to the cover 31 via bolts 4, facilitating the installation of the anti-vibration assembly. The sliding assembly 2 includes a slide rail 21, a slide seat 22, and a matching plate 23. The slide seat 22 is mounted on the slide rail 21, the matching plate 23 is mounted on the slide seat 22, and the cover 31 is connected to the matching plate 23. The slide seat 22 can slide relative to the slide rail 21. The matching plate 23 is fixedly connected to the slide seat 22, thereby enabling the matching plate 23 to drive the anti-seismic assembly and the mounting plate to slide and adjust the position of the mounting plate. The matching plate 23 is provided with a matching hole 231, which corresponds to the through hole 313 of the cover 31. The bolt 4 is inserted through the matching hole 231 and the through hole 313 and then locked, facilitating assembly and disassembly.

[0019] The earthquake-resistant high and low voltage switchgear of this embodiment can facilitate the rapid assembly of earthquake-resistant components and facilitate assembly; at the same time, it can protect important electrical components and facilitate maintenance.
