Energy-saving outdoor ring main unit

Abstract

The invention discloses an energy-saving outdoor ring main unit. The energy-saving outdoor ring main unit comprises a cabinet body, an exhaust fan, a sealing plate, a solar panel and a damping mechanism. The exhaust fan is employed to guide an air flow during work to allow air to directionally circulate in the cabinet body from bottom to top so as to ensure the cooling effect; when fire occurs inthe cabinet body, a smoke alarm is started, a circuit board controls rotation of a motor after receiving alarm signals so as to allow a through hole to be staggered with an air outlet hole to cut offthe air circulation and avoid the further aggravating of the fire; a solar panel is configured to convert solar energy to electric energy for use of a storage battery so as to achieve the effect of fully utilizing the solar energy, and energy conservation and environment protection are better; the damping mechanism is arranged to buffer the external force of the cabinet body so as to reduce the shake of the cabinet body, prevent electrical components in the cabinet body from being damaged, the cabinet body is configured to buffer the external force from different directions through arrangementof a first connection rod and a second connection rod, and the buffer effect is better.

Description

technical field [0001] The invention relates to an electrical device, in particular to an energy-saving outdoor ring network cabinet. Background technique [0002] The ring network cabinet is a group of transmission and distribution electrical equipment (high-voltage switchgear) installed in a metal or non-metal insulated cabinet or made into an assembled interval ring network power supply unit. Its core part uses load switches and fuses. It has a structure Simple, small size, low price, can improve power supply parameters and performance, and power supply security and other advantages. It is widely used in distribution stations and box-type substations of load centers such as urban residential quarters, high-rise buildings, large public buildings, factories and enterprises. [0003] The structure of the ring network cabinet is simple, the operation is reliable and safe, the maintenance amount is small, and the operating cost is low. However, the equipment and cables in the...

Problems solved by technology

[0003] The structure of the ring network cabinet is simple, the operation is reliable and safe, the maintenance amount is small, and the operating cost is low. However, the equipment and cables in the ring network cabinet are relatively concentrated, so it is necessary to maintain a good ventilation environment to achieve the purpose of cooling. Most of the network cabinets solve this problem by opening ventilation holes, but the normally open ventilation holes will cause a new problem, that is, when a fire occurs in the ring network cabinet, the air entering the ring network cabinet through the ventilation holes will It will promote the burning of the flame, which will lead to the further aggravation of the fire
