Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples are used for illustrating the present invention, but are not used for limiting the scope of the invention.
Shown in Fig. 4, what the present embodiment provided prevents that the interlock plate of mistakenly entering charged chamber from comprising strip mainboard 1, perpendicular to first mounting panel 2 on the long limit of described mainboard 1 one sides, while is perpendicular to the second mounting panel 3 of described mainboard 1 and the first mounting panel 2, the second mounting panel 3 is the right angle corner opening shutoff of mainboard 1 and first mounting panel 2 one end, realizes mainboard 1, the first mounting panel 2 and the second mounting panel 3 and form a drift angle structure of cuboid; The length of the first mounting panel 2 is greater than mainboard 1, i.e. outstanding mainboard 1 certain length of the first mounting panel 2, first mounting panel 2 other ends are provided with the perpendicular bending wing 4, relative the first mounting panel 3 thickness and width, the bending wing 4 and mainboard 1 are all positioned at the first mounting panel 2 both sides, say more intuitively, from a side of interlock plate, the bending wing 4, the first mounting panel 2 and mainboard 1 form the vertical zigzag structure of adjacent both sides difference; The first mounting panel 2 middle parts also offer stopper slot 5.
Particularly, on described the second mounting panel 3 and the bending wing 4, all offer manhole, the first through hole 7 on the bending wing 4 in as shown and the second through hole 8 on the second mounting panel 3; Described first mounting panel 2 other ends are provided with slotted hole 6, and slotted hole 6 arranges near the bending wing 4, and the length direction of slotted hole 6 is consistent with the length direction of the first mounting panel 2.
The above-mentioned interlock plate that prevents mistakenly entering charged chamber, is mainly used in high voltage switchgear, to improve the fail safe of its use.When described interlock plate is arranged in high voltage switchgear, mainly be associated with the structure of high-tension switch cabinet, shown in Fig. 5 and Fig. 6, particularly, the described bending wing 4 drives bearing pin 10 to be connected by the first through hole 7 of offering on it with shutter, and drives the slotted hole of bearing pin 10 bending sides through shutter; The first mounting panel 2 can be arranged on guiding fixed head 9 along its length movably; The second mounting panel 3 is connected with the lower door bolt 15 of high-tension switch cabinet subjacent cable chamber 18, on described lower door bolt 15, is arranged with return spring 16.Limit shaft 14 in described high-tension switch cabinet can block in described stopper slot 5; Described shutter drives the handle hole shutter 12 of bearing pin 10 connecting valve operating axis 13, and when described limit shaft 14 blocks are in the time that stopper slot 5 is interior, described return spring 16 is compressed, and described handle hole shutter 12 leaves switching manipulation axle 13, described cable vault 18 door locked; In the time that described limit shaft 14 departs from stopper slot 5, described return spring 16 is stretched, and described handle hole shutter 12 blocks switching manipulation axle 13, and the release of 18 of described cable vaults can be opened.
Wherein, described the first mounting panel 2 is pressed close to described guiding fixed head 9 and is arranged, on described the first mounting panel, 2 offer slotted hole 6, in this slotted hole 6, pass guiding bearing pin 11, the first mounting panel 2 is arranged on guiding fixed head 9 movably by this slotted hole 6 and guiding bearing pin 11, with plain cushion, bullet pad and nut are fixed on the first mounting panel 2, and require slotted hole 6 on guiding bearing pin 11, to slide vertically flexibly.The second through hole 8 is fixed on the internal thread hole of lower door bolt 15 by bullet pad, plain cushion by screw.Lower door bolt 15, through a through hole on cabinet 17, can move up and down flexibly, according to the principle of two point location one lines, thereby makes interlock plate vertical up-or-down movement flexibly.
The high voltage switchgear of the present embodiment is under the combined floodgate running status shown in Fig. 5, and due to the restriction of limit shaft 14, lower door bolt 8 cannot upwards be mentioned, thus the aggressive mistakenly entering charged chamber that prevented.
In the time that switching manipulation axle in Fig. 5 13 carries out sub-switching operation, interlock limit shaft 14 is to left horizontal movement, and after switching manipulation axle 13 sub-switching operations complete, the state of limit shaft 14 is as shown in position in Fig. 6, and interlock plate is no longer restricted.Now descend door bolt 15 can up mention and propose outward, instantly after the constraint of door bolt 15 Bu Shou cable vaults 18, interlock plate, upwards sling movement of lower door bolt 15 under the active force of return spring 16, handle hole shutter 12 drives bearing pin 10 to drive the slotted hole of its bending side to do fixed point clockwise rotation by shutter, and now state as shown in Figure 6.Under the effect of return spring 16 potential energy, handle hole shutter 12 is keeping the inactive state that switch operating axis 13 is blocked, thereby restriction is carried out closing operation to switch operating axis 13, and switch cannot be switched on, and just can carry out safety work in cable vault 18.
In the time of needs closing operation, must detain the draw-in groove of door bolt 15 to put to pressing down cable vault 18, overcome under the effect of return spring 16 elastic force at cable vault's 18 gravity, can carry out closing operation to the switching manipulation axle of switch 13, until operated, recovering state is to the combined floodgate running status of Fig. 5 high-tension switch cabinet, limit shaft 14 limits the vertical up-or-down movement of interlock plate, handle hole shutter 12 keeps not occlusion state under the effect of shutter driving bearing pin 10, the restriction that cable vault 18 is subject to lower door bolt 15 draw-in grooves also cannot be opened and be entered cable vault 18, avoid mistakenly entering charged chamber.
As can be seen from the above embodiments, the present invention is by the setting of interlock plate, and can realize high-tension switch cabinet and close a floodgate operation time, cable chamber door is locked, can mistakenly entering charged chamber, and switching manipulation axle is opened, and can carry out closing operation; When high-tension switch cabinet separating brake is stopped transport, cable chamber door is released, and switching manipulation axle is blocked, thus restriction closing operation, switch cannot be switched on, and cable vault can carry out safety work.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, do not departing under the prerequisite of the technology of the present invention principle; can also make some improvement and replacement, these improvement and replacement also should be considered as protection scope of the present invention.
