When the dress was hung at the cabinet door when on the cabinet body door frame, the pendant corresponds the hook cooperation on pendant and the door frame on the cabinet door for have stronger structural strength between cabinet door upper end and the door frame, high-pressure gas is difficult to here with cabinet door top-open, and then high-pressure gas and arcing can not be from this place a large amount of blowout.
Description
Technical Field
The invention belongs to the technical field of power switch equipment, and particularly relates to a switch cabinet for preventing arcing blowout.
Background
The ring distribution network needs to use a switch cabinet when the power is supplied to the outside through a distribution branch, and the switch cabinet is generally called a ring main unit. For such switch cabinets, the internal arcing fault is a frequent and catastrophic serious fault, and once the fault occurs, huge sound, light, electricity, heat and other energy can be radiated, high-pressure gas generated by the fault arc is released in a gas explosion manner within a short time, so that strong impact force is generated on the cabinet body, the arcing and the high-pressure gas are sprayed out from the gap of the cabinet body, and even the cabinet body can be directly burst, so that operators and personnel around equipment are seriously injured.
The structural strength's of the general reinforcing cabinet door of adoption of prior art mode solves above-mentioned problem, if grant publication number is CN201518390U, application date is 2009.09.24's chinese utility model patent discloses a prevent looped netowrk cabinet lower door, a plurality of inserted sheet formula couple is installed on both sides about the door main part inboard of this looped netowrk cabinet lower door, be provided with on the door frame of the cabinet body with inserted sheet formula couple one-to-one and matched with slot, couple and slot have constituted a movable knot structure jointly, this kind of movable knot structure has strengthened the joint strength between the door both sides and the cabinet body, when electric arc trouble, can prevent that the door is bounced out when internal pressure is too big.
However, the direct plane laminating in upper end of current cabinet door upper end direct and looped netowrk cabinet door frame usually, fixed connection mainly relies on about and the bottom realizes hanging the dress fixed, so, the cabinet door top just forms weak area, when breaking down, high-pressure gas in the cabinet is easy here with cabinet door upper end back-open, leads to high-pressure gas and arcing to spout from this place a large amount and then harm personnel around the equipment.
Disclosure of Invention
