Abstract
The utility model discloses an alternating-current low-voltage distribution cabinet, and the cabinet comprises a cabinet body. The interior of the cabinet body is provided with a combined-type bus clamp, a bus, a knife switch, a circuit breaker, a current transformer, and an insulator. The cabinet body is provided with a cabinet door which is movably connected with the cabinet body. The cabinet door is provided with a glass observation window which is double-layer toughened glass, wherein a metal shielding mesh is embedded in the double-layer toughened glass. The glass observation window has an anti-explosion function and a shielding function, and is made of toughened glass, so the glass observation window has enough transparency which helps an observer to observe the operation condition and position of an internal element. In addition, a good performance of heat dissipation is achieved through the arrangement of a ventilator, a ventilating hole, and a heat-dissipation groove hole. The cabinet provided by the utility model guarantees the reliability and safety protection of power supply.
