Electrical ring main unit with built-in fireproof and anti-explosion structure and assembling method of electrical ring main unit

Abstract

The invention discloses an electrical ring main unit with a built-in fireproof and anti-explosion structure and an assembling method thereof, and particularly relates to the field of a solar photovoltaic power generation assembly. The electrical ring main unit comprises a ring main unit body, the ring main unit body is provided with two cabinet doors, the two cabinet doors are connected with transition mechanisms, the two transition mechanisms are connected with buffer mechanisms, the ring main unit is connected with a placing mechanism, a fire extinguishing mechanism is placed in the placing mechanism, the placing mechanism is connected with a cooling mechanism, and the inner top end of the ring main unit is connected with an output mechanism connected with the fire extinguishing mechanism. The ring main unit can extinguish fire in time, the loss of the ring main unit is further prevented from being too large, later maintenance of maintenance personnel is facilitated, meanwhile, the buffer air bag on the ring main unit can also reduce the impact force of impurities, the cabinet door is prevented from being collided to be opened, and external personnel and objects are protected.

Description

Technical field [0001] The present invention relates to the field of outdoor electrical ring network cabinets, and more particularly, the present invention relates to an electrical ring cabinet and an assembly method thereof in an internal fire explosion-proof structure. Background technique [0002] The ring network cabinet is an electrical equipment in which the localized electrical equipment is mounted in a metal or non-metallic insulating cabinet or to assemble the spacer network power supply unit, and its core part uses a load switch and a fuse, which has simple structure, small size. The price is low, and the power supply parameters and performance can be improved and the power supply safety can be improved. It is widely used in the distribution station of urban residential communities, high-rise buildings, large-scale public buildings, factory enterprises, and box substations. [0003] In the process of use, the electrical ring network cabinet can be placed outdoors. Durin...

AI Technical Summary

Problems solved by technology

[0003] In the actual situation, the electrical ring network cabinet can be placed outdoors for use. In the process of outdoor use, due to the relatively high power supply pressure and the high outdoor temperature, it is easy to cause the electrical ring network cabinet to appear. Short circuit, which leads to a fire in the electrical ring network cabinet, and the existing electrical ring network cabinet cannot deal with the fire caused by the short circuit in time during the use, which leads to the overall damage of the electrical ring network cabinet, and further leads to economic losses. The expansion also affected the staff's subsequent recovery process
