Abstract
The invention discloses a rear-door interlocking mechanism for a centrally-mounted switch cabinet, which comprises an upper door and a lower door, wherein the back surface of the upper door is vertically connected with a first elbow, and the downward side of the first elbow is vertically connected with a second elbow; the back surface of the lower door is vertically connected with a third elbow; and the second elbow is in contact with the third elbow when moving forwards to a limiting position. According to the invention, rear doors of a switch cabinet comprise upper and lower doors, and mechanical interlocking is performed between the upper and lower doors, so that the upper door can be opened just after the lower door is opened, and the upper and lower doors can be matched with other components in the switch cabinet to complete mechanical interlocking or electric interlocking, thereby greatly improving the maintenance efficiency and improving the application flexibility of the centrally-mounted cabinet.
Description
Technical field
The present invention relates to intermediate switchgear cabinet, be specifically related to the interlocking device between a kind of upper and lower door at two-door formula cabinet back door of intermediate switchgear cabinet.
Background technology
Along with intermediate switchgear cabinet being widely used in electric power system, the electricity consumption occasion under the various environment can both be seen its figure.Traditional intermediate switchgear cabinet is derived from early stage fixed switch cubicle; Its cabinet back door is the whole door of a fan, relies on high-intensity screw to shut, and is difficult for opening; This kind design is applicable to the mode that power distribution cabinet leans on wall to install, and when normal the use, need not consider the problem that open at the cabinet back door.But do not lean under the mode that wall installs at power distribution cabinet, this kind design is not just considered the repair and maintenance problem, need open the very inconvenience that seems under the occasion at cabinet back door in cable construction or repair and maintenance etc.Therefore existing intermediate switchgear cabinet has adopted new locking mode, and its cabinet back door can cooperate with electromagnetic lock accomplishes electrical interlock, guarantees in intermediate switchgear cabinet, just can open the cabinet back door under the uncharged situation; Perhaps cooperate and accomplish mechanical interlocking, guarantee after earthed switch closes a floodgate, just can open the cabinet back door with earthed switch.
On the other hand, the cabinet height of considering intermediate switchgear cabinet is all more than 2 meters, and the whole door of a fan is adopted at the cabinet back door, the distortion of cabinet door easy shaking, and mechanical strength is not high.Therefore can consider to have made the cabinet back door into the form of upper and lower two fan doors.But still only dispose an electromagnetic lock or earthed switch lock this moment, and electromagnetic lock or earthed switch lock operated by rotary motion are in the position of Xiamen.In view of this, how to guarantee the consistency of interlocking between the upper and lower door, make and after open the Xiamen, can open to the doorstep, with regard to the problem that needs in the design that becomes intermediate switchgear cabinet to consider.
Summary of the invention
To the problems referred to above at existing intermediate switchgear cabinet cabinet back door, the applicant improves through research, and a kind of intermediate switchgear cabinet cabinet back door interlocking device is provided, to guarantee the interlocking property between the upper and lower door in intermediate switchgear cabinet cabinet back door.
Technical scheme of the present invention is following:
A kind of intermediate switchgear cabinet cabinet back door interlocking device comprises to the doorstep and the Xiamen that the said back side of calling vertically is connected with first bending, and the below of first bending vertically is connected with second bending; The back side of said Xiamen vertically is connected with the 3rd bending; When moving forward to extreme position, said second bending contacts with said the 3rd bending.
Its further technical scheme is: the front of said second bending vertically is connected with the 4th bending, and said the 4th bending is positioned at the below of the 3rd bending.
Its further technical scheme is: electromagnetic lock or earthed switch are installed on the said Xiamen.
Its further technical scheme is: said to the doorstep or the Xiamen be provided with observation window and illuminating lamp.
Useful technique effect of the present invention is:
Two fan doors are up and down adopted at cabinet of the present invention back door; Last Xiamen has mechanical interlocking each other; So that after open the Xiamen, can open to the doorstep; And can cooperate with other components and parts in the cabinet and accomplish mechanical interlocking or electrical interlock, improve the efficient of maintenance greatly, improve the flexibility that mid-cabinet uses.

Fig. 2 is the oblique view at intermediate switchgear cabinet cabinet back door.
Fig. 3 is the cutaway view at interlocking device place.
Embodiment
Further specify below in conjunction with the accompanying drawing specific embodiments of the invention.
Like Fig. 1, shown in Figure 2, the present invention by to the doorstep 1, Xiamen 2 forms.As shown in Figure 3, to the doorstep the below that vertically is connected with first bending, 3, the first bendings 3,1 the back side vertically is connected with second bending 4; The back side of Xiamen 2 vertically is connected with the 3rd bending 5.Second bending 4 is positioned at the 3rd bending 5 rears, under the situation about not opening in Xiamen 2, along with 1 open to the doorstep, when second bending 4 moves forward to extreme position, will contact with the 3rd bending 5.Said structure has formed the pattern of a snap close between the top of to the doorstep 1 bottom and Xiamen 2, under the prerequisite of only guaranteeing to open in Xiamen behind the cabinet 2, can open to the doorstep 1.
As shown in Figure 3, positive vertical connection the 4th bending 6, the four bendings 6 of second bending 4 are positioned at the below of the 3rd bending 5 again.The 4th bending 6 is a stiffening device, to improve mechanical strength.
Like Fig. 1, shown in Figure 2, in addition, can place observation window 9 on the Xiamen 2 so that observe the action situation of components and parts in the cable vault; Place cable vault's illuminating lamp 10 so that solve the dim situation about can't observe of sight line; Once more, can cooperate with electromagnetic lock 7 and accomplish electrical interlock, guarantee in mid-cabinet, just can open the back door under the uncharged situation; Also can cooperate and accomplish mechanical interlocking, guarantee after earthed switch closes a floodgate, just can open the back door with earthed switch 10.Thus, the perfect security performance of mid-cabinet has improved the efficient of electrical verification maintenance greatly, has improved the flexibility that mid-cabinet uses greatly.
Above-described only is preferred implementation of the present invention, the invention is not restricted to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from basic design of the present invention, all should think to be included within protection scope of the present invention.
