Description

Technical Field

[0001] The utility model relates to the technical field of high and low voltage distribution cabinets, in particular to an explosion-proof high and low voltage distribution cabinet with safety and stability. Background Technique

[0002] High and low voltage distribution cabinets are power distribution equipment differentiated according to voltage levels. Among them, the voltage level of high voltage distribution cabinets is generally above 10 kV, while that of low voltage distribution cabinets is below 3 kV. They integrate multiple functions such as switches, protection, measurement, and monitoring to achieve efficient management and control of the power system. The explosion-proof high and low voltage distribution cabinet is based on the traditional high and low voltage distribution cabinet and adds an explosion-proof performance design, which aims to prevent explosions caused by internal failures or external factors of electrical equipment in flammable and explosive environments, thus protecting the safety of personnel and equipment.

[0003] A remotely monitorable high and low voltage explosion-proof distribution cabinet with the Chinese utility model publication number CN217642243U includes an explosion-proof outer cabinet, and a distribution inner cabinet is arranged inside the explosion-proof outer cabinet. By setting adjusting screw columns, mounting sleeves, turntables, elastic rods, support plates, support rods, and limit slides, it is almost impossible to move the distribution cabinet after it is installed in a specific position. Once there is water accumulation in the installation area, the distribution cabinet is easily damaged by moisture. When there is water accumulation, the turntable can be rotated. The turntable drives the adjusting screw column to rotate, and the mounting sleeve outside the adjusting screw column drives the explosion-proof outer cabinet to move upward. The distance between the explosion-proof outer cabinet and the ground can be adjusted, so that even if there is water accumulation, the distribution cabinet will not be immersed in water. When the explosion-proof outer cabinet moves up and down, the support plate at its bottom can support it. This structure realizes the adjustable height of the distribution cabinet and reduces the occurrence of water accumulation and moisture.

[0004] The above patent realizes the adjustable height of the distribution cabinet and reduces the occurrence of water accumulation and moisture. However, during actual use, when repairing the electronic components inside the distribution cabinet of the above patent, it is usually necessary for the staff to put their heads into the explosion-proof outer cabinet and the distribution inner cabinet to repair the electronic components of the distribution inner cabinet. Since the distribution cabinet is closed, the internal space is limited, and the light is also easily blocked, which leads to limited operation space and blocked vision for the staff to repair, reducing the repair speed. Therefore, an explosion-proof high and low voltage distribution cabinet with safety and stability is now proposed. Content of the Utility Model
