Abstract

The invention provides a lightning-proof outdoor power distribution cabinet. The power distribution cabinet comprises a lightning rod, a rainshed, a cabinet body, a grounding copper wire, hinges, a cabinet door, a lock of the cabinet door and an electrical junction box, wherein the rainshed is arranged in the upper portion of the cabinet body, the lightning rod is arranged in the left upper portion of the cabinet body, the cabinet door is arranged on the cabinet body via the hinges, the lock of the cabinet door is arranged in the right side of the cabinet door, the lower end of the cabinet body is connected with the grounding copper wire, and the electrical junction box is arranged in the cabinet body. Due to arrangement of the lightning projection module, the electrical junction box and the rainshed, the lightning proof effect is good under the condition that an impact grounding resistor of the ground network cannot meet the requirements or is not grounded; the lightning-proof device is integrated with the power distribution device to form the lightning-proof power distribution box with both lightning-proof and power distribution functions; and the sealing performance of the electrical junction box is improved to solve the problems of short circuit or circuit break caused by that water or other impurities enter the outdoor distribution box.

Description

technical field [0001] The invention relates to the technical field of electrical distribution cabinets, in particular to an outdoor lightning protection distribution cabinet. Background technique [0002] Power distribution box is assembled in closed or semiclosed metal safe by electrical wiring requirement by switchgear, measuring instrument, protective device and auxiliary equipment or on screen width, forms low-voltage distribution equipment. During normal operation, the circuit can be connected or disconnected by means of a manual or automatic switch. Cut off the circuit or alarm with the help of protective electrical appliances in case of failure or abnormal operation. Various parameters in operation can be displayed by means of measuring instruments, and some electrical parameters can also be adjusted to prompt or send out signals for deviations from normal working conditions. Commonly used in various power generation, distribution and substations. [0003] At pr...
