Description

Technical Field

[0001] The utility model relates to the field of low-voltage power cabinets, in particular to a low-voltage power cabinet with a fire protection structure. Background Art

[0002] The low-voltage power cabinet is suitable for power supply systems with a frequency of 50-60Hz, a voltage of 380V-460V, and a rated current of less than 1000A. It can be used for power supply, motor control and lighting. The power cabinet can be divided into two types: outdoor and indoor. From the installation point of view, it can be divided into two types: hanging type and floor-standing type. From the size point of view, it can be divided into two types: power cabinet and power box. Compared with the low-voltage distribution cabinet, the power cabinet is relatively compact in size, reducing the floor space. Since the power load of the power cabinet is mainly inductive load. Therefore, the instantaneous overload capacity of the circuit breaker (switch) in the cabinet is required to be strong, the arc extinguishing performance is good, and the reliability of connection is high. The main function of the low-voltage power cabinet is to distribute power to the next-level distribution point or each power point, that is, to distribute each power line as required. One of the most significant uses is to facilitate the configuration of power supply in different regions or categories. When a line fails, it is conducive to controlling the scope of the fault and conveniently and quickly finding the fault point to eliminate it in time. If it is related to electricity, it needs to involve fire protection, so we are required to make a low-voltage power cabinet with a fire protection structure. Most traditional low-voltage power cabinets have bolt-hinged doors, but they are prone to aging and falling off when exposed to wind and rain outdoors, exposing the internal structure and causing danger. Therefore, the aging door structure needs to be replaced, causing inconvenience in use. Utility Model Content
