Edge dividing plate 17 is into and out that is, the gap with insulating barrier coordinates.
Referring to Fig. 2 c and Fig. 2 d, in fixed cabinet, the second interlocking mechanism is additionally provided with, it includes：One interlocking mechanism's seat board 13,
To be fixed on the channel-section steel in cabinet, second group of upright opening is installed with two wing plates setting up and down；One the second interlocking shaft 9 erect, it is
Middle thin thick three sections of multi-diameter shafts up and down, top are supported with the second roller 6, lower end through connection by laterally the second fixed pin shaft 8
Second group of upright opening on 13 liang of wing plates of latch mechanism seat board, the second bullet is cased with the second interlocking shaft axle body between two upright openings
Spring 12, the second interlocking shaft axle body in second spring 12 are provided with bulge loop.
Referring to Fig. 2 c, Fig. 2 d, Fig. 6 a and Fig. 6 b, a second horizontal interlock plate 10, one end is fixed on the front door of fixed cabinet
Inner side, is provided with the circular hole that can coordinate the hypomere diameter of the second interlocking shaft 9 with gap in other end plate face, and the outermost end of circular hole is provided with scarce
Mouthful, the width of breach coordinates the interlude diameter of the second interlocking shaft 9 in which can free in and out；The position that second interlock plate 10 is fixed should make
The hypomere for obtaining the second interlocking shaft 9 is just stuck in the circular hole in the other end plate face of the second interlock plate 10；Second roller 6 is then located at absolutely
The position that can be press against down in the insertion process of edge dividing plate 17.
In this way, the second interlocking shaft 9 can be pressed down and can automatically reset.Usually, the hypomere of the second interlocking shaft 9 is just stuck in
In circular hole in the other end plate face of second interlock plate 10 so that front door can not open.Only pressed when insulating barrier 17 inserts
Lower second roller 6, related second interlocking shaft 9 are pressed down, the thinner stage casing of the second interlocking shaft 9 has been alignd, and the second interlock plate 10 is another
During the breach of end plate face circular hole, front door could open.Realize that insulating barrier is not inserted into front cabinet door in cabinet and can not open purpose.
See also Fig. 2 c and Fig. 2 d, the first interlocking mechanism is additionally provided with fixed cabinet, it includes：On interlocking mechanism's seat board 13
First group of upright opening being also installed with lower two wing plates；One the first interlocking shaft 5 erect, bottom pass through laterally the first fixed pin shaft 15
The first roller 16, stage casing are supported with through first group of upright opening on 13 liang of wing plates of interlocking mechanism's seat board, in first group of upright opening
Between the first interlocking shaft axle body on be cased with the first spring 11, the first interlocking shaft axle body on the first spring 11 makes provided with bulge loop
Obtaining the first interlocking shaft 5 can be pressed down and can automatically reset；One piece of first interlock plate 14, one end are fixed in the front door of fixed cabinet
Side, the other end have the inclined-plane tilted upward, and fixing end should cause inclined-plane to press against the first roller 16, the first interlocking shaft 5 when fixing
The position being pressed down；In insulating barrier plate face, the position of the upper end of the first interlocking shaft 5 is provided with after correspond in insulating barrier insertion cabinet
Circular hole 100, and insulating barrier is pinned in the upper end of the first interlocking shaft 5 in free state through circular hole.
Fixed cabinet is overhauled, to ensure maintainer's personal safety, it is necessary to isolate to once powered position, specifically
Operation is as follows：
Such as Fig. 3, GN22 disconnecting switch 1 is in gate-dividing state, and disconnecting switch top carries high-tension electricity, now forbids opening admittedly
Determine cabinet front door 2, the second interlock plate 10 is clasped by the second interlocking shaft 9, realizes that front door is not switched on；
Such as Fig. 4, front door shrouding 7 need to be pulled down, insulating barrier 17 is inserted from front door by insulating barrier left and right rail plate 3
To cabinet, now the second roller 6 is depressed, and drives the second interlocking shaft 9 to move downward, now the second interlock plate 10 is not by second
Interlocking shaft 9 clasps, and such front door 2 can be opened；
After front door 2 is opened, because the first interlock plate 14 does not push down the first roller 16, the first interlocking shaft 5 passes through first
The pressure of spring 11 recovers motion upwards, finally clasps insulating barrier 17, is specifically shown in Fig. 5, now insulating barrier can not be extracted out artificially.
This set interlocking mechanism can meet that insulating barrier is not inserted into cabinet, and front cabinet door can not be opened；Front cabinet door is not shut, insulation
Dividing plate can not be extracted out.
