Tail-breaking type ring main unit with anti-riot function

Abstract

The invention discloses a tail-breaking type ring main unit with an anti-riot function, belongs to the field of ring main units, and aims to provide a tail-breaking type ring main unit with an anti-riot function. When a thief wants to destroy a cabinet door to steal an electric appliance in the ring main unit, the thief violently disassembles an outer cabinet door on the outer side, under the action of external force, a connecting column is easy to break from the position where a prefabricated annular groove is located, and in the process of separating an inner cabinet door from the outer cabinet door, barbs can cause the elastic fibers to be pulled apart, irritant substances located in the elastic fibers can be sprayed out under the action of high-pressure gas filled in the elastic cavities, and thieves are repelled. According to the ring main unit, a duplex cabinet door for the ring main unit can be designed by simulating the tail breakage phenomenon existing in the nature, the duplex cabinet door prevents the whole cabinet door of the ring main unit from being damaged violently, and meanwhile, after one layer of cabinet door is disassembled violently, stolen objects can be expelled through irritant substances at the filler spraying position between the interlayers of the cabinet door.

Description

technical field [0001] The invention relates to the field of ring network cabinets, and more specifically relates to a tail-broken ring network cabinet with anti-riot function. Background technique [0002] The ring network refers to the ring distribution network, that is, the main power supply line forms a closed ring, and the power supply supplies power to the ring main line, and then distributes power from the main line through high-voltage switches one by one. The advantage of this is that each power distribution branch can get power from its left main line and from its right main line. When the left main fails, it continues to receive power from the right main, and when the right main fails, it continues to receive power from the left main, so that although the main power supply is single, But from each power distribution branch, it can get benefits similar to dual-circuit power supply, thereby improving the reliability of power supply, and the ring network cabinet is ...

AI Technical Summary

Problems solved by technology

[0004] The ring network cabinet, like most power infrastructure, will be coveted by some thieves, who will steal various electrical appliances in the ring network cabinet to sell illegal income, because the door of the ring network cabinet is the only The movable parts are usually easy to disassemble, and there is no need to use large-scale equipment for destructive disassembly, so most thieves will give priority to destroying the cabinet door to achieve the purpose of theft, and once the thief steals various electrical appliances in the ring main unit Destruction can easily cause partial power supply failures in the ring distribution network, affecting users' normal power consumption experience
