By the mechanical component design, sufficient mechanical strength is guaranteed, the middle-arranged door can be opened and closed optionally, the door is prevented from being broken through to injure staff caused by loss screwed bolts, troubles that staff injured by accidents are solved fundamentally and completely, and the purpose of protecting operators is achieved.
Description
Technical field
The present invention relates to a kind of high-voltage board, relate in particular to the anti-arcing lever gear door of a kind of high-tension switch cabinet device.
Background technology
Though voltage switchgear itself should possess machinery " five is anti-" function, with regard to its function, also can't reach perfect.High-tension switch cabinet mainly can cause following fault when operation;
1) the normal separating brake of load short circuit (vacuum circuit-breaker);
2) equipment of itself inside causes arcing.
Above-mentionedly either way will produce a large amount of arcing gases, because the intensity of arcing gas is big, may release from mid-door.This moment, mid-door can not be opened ejection automatically when the breaker chamber door impacted, and the personnel to operating that cause directly injure.Common way was to install door lock additional and to adopt the reinforcing screw after circuit breaker (mid-door) the hinge reinforcing during high-tension switch cabinet designed.And cause the reason of operating personnel injury is normally untied earlier when reinforcing the screw door and also not opening, this moment as the arcing residual gas baric flow that is short-circuited are opened door just to cause operating personnel are injured.、
Existing mid-door is mainly: the offside door of door is provided with 2 on hinge, and wherein base is fixed on the column, and another side then is fixed on the mid-door, realizes the switching function of door; The right side is equipped with door lock one (turn 90 degrees and door can be opened) to the right otherwise the Men Guanhou screw key can be able to be pinned.But door lock and handle for one so utilize handle with regard to the open and close door during open and close doors.Because standing nonflammable arc air pressure, the door latch bad mechanical strength impacts, so also need 3 of ad hoc 10mm hexagon socket head cap screws when equipment moves, 10mm hexagon socket head cap screw sth. made by twisting tightly must be guaranteed safety in order to fix (with cap spiral shell technology with fixed by nut on the right column) with the right side column on the right side.Reached anti-arcing air pressure impact function on effect, but that its shortcoming is the switch door is very inconvenient, more groove is that bolt is not twisted with the fingers tightly and might be caused personal injury.
Summary of the invention
The present invention mainly provides the anti-arcing lever gear door of a kind of high-tension switch cabinet device, untiing when reinforcing the screw door and also not opening mid-door in order to solve in the existing product, suddenly being short-circuited produces arcing residual gas baric flow and mid-door is washed open, causes the technological deficiency to operating personnel's injury.
The present invention is achieved by the following technical solutions:
