Abstract
The utility model relates to a misoperation preventing device for high-voltage load switch cabinet. The utility model is characterized in that a lock plate with a lock hook is arranged on a switch cabinet door, a lock rod is fixed on an operating wheel, an operating wheel shaft or a frame for the switch cabinet is provided with a fending sheet used for fending the operating hole of the operating wheel, and a pushing block is arranged on the switch cabinet door. The utility model has the advantages that the operating wheel and the switch cabinet door are used for carrying out the mechanical interlock, the structure is simple and reliable, the operation is convenient, the lock can be unlocked emergently, and the utility model can be used for the switch cabinet provided with a load switch or a vacuum switch.
Description
The utility model relates to the misoperation apparatus that prevents that a kind of high voltage load switch cabinet uses.
Existing high voltage load switch cabinet for preventing misoperation, generally uses electronic procedure lock.This lock construction is complicated, and operating difficulties is difficult for grasping, and the user reflects that generally use is inconvenient.
The purpose of this utility model is to provide a kind of simple in structure, easy to operate, safe and reliable mechanical interlocking anti-misoperation apparatus for overcoming above-mentioned the deficiencies in the prior art part.
The utility model is to adopt following two technical schemes to realize:
Scheme one: on the door of loading switch cabinet, the jam plate that has latch hook is installed, the locking bar that cooperates with latch hook is fixed on the hand wheel of loading switch cabinet, on the operation wheel shaft, the shielding plate that can block the hand wheel handle hole is housed, and on the relevant position of switch cubicle door, is provided with jacking block.
Scheme two: the jam plate that has latch hook is installed on the loading switch cabinet door, the locking bar that cooperates with latch hook is fixed on the hand wheel of on-load switch, on the framework of switch cubicle, mounting panel is housed, be fixed with little axle on it, on little axle, the shielding plate that can block the hand wheel handle hole is housed, and on the relevant position of switch cubicle door, is provided with jacking block.
When the door of loading switch cabinet was opened, the handle hole on the hand wheel was downward, and this moment, shielding plate blocked the handle hole on the hand wheel, reached the purpose that on-load switch can not close a floodgate.When door of off switch cabinet, the jacking block on the door is pushed shielding plate open, exposes the handle hole on the hand wheel, and on-load switch can close a floodgate at this moment.When moving hand wheel and upwards rotate (about 90 ° of angles), promptly when on-load switch closed a floodgate, the locking bar on the hand wheel is rotation thereupon also, enters in the latch hook of jam plate, and door is pinned reliably.The door of switch cubicle was operated the wheel interlocking and was in the state that shuts reliably this moment, and door can not be opened.Just in case accident appears in switch cubicle, in the time of must opening, unclamp the hold-down screw of jam plate, just but emergency release.
The utility model utilizes the hand wheel of on-load switch and switch cubicle door to carry out mechanical interlocking, reaches the purpose that prevents misoperation.Simple in structure, reliable, easy to operate, and can emergency release, can be widely used in being equipped with the switch cubicle of on-load switch and vacuum switch.
Fig. 1 is the structural representation of the utility model scheme one embodiment;
Fig. 2 is the structural representation of the utility model scheme two embodiment;
Fig. 3 is the A-A cutaway view of Fig. 2.
Below in conjunction with embodiment and accompanying drawing the utility model is further described.
Embodiment one: with reference to Fig. 1, this anti-misoperation apparatus is made up of jam plate 5, latch hook 12, locking bar 11, shielding plate 7.Position shown in the figure is the position of hand wheel 6 when being in "on" position.Jam plate 5 is fixed on the door 2 of switch cubicle by mounting screw 3, and latch hook 12 is fixed on the inboard of jam plate 5, and locking bar 11 is fixed on the relevant position of on-load switch hand wheel 6.Adorn an axle sleeve 10 on the axle of hand wheel 6, shielding plate 7 is fixed on the axle sleeve 10.Be with spring 8 on axle sleeve 10, an end hook of spring hangs on the shielding plate 7, and the other end is stuck on the framework 1 of switch cubicle.Shielding plate is L shaped.When the switch cubicle door was opened, the handle hole 4 on the hand wheel was just in time blocked in the position of shielding plate 7.Also can be on shielding plate with the printed words of " please don't operate ", to guarantee that on-load switch is not closed a floodgate.On the switch cubicle door, and fix a jacking block 9 on the corresponding position of shielding plate, its effect is at closing time shielding plate to be pushed open, to expose the handle hole on the hand wheel, so that the on-load switch closing operation.
Embodiment two: with reference to Fig. 2, Fig. 3, this anti-misoperation apparatus is made up of jam plate 5, latch hook 12, locking bar 11, shielding plate 7.Position shown in the figure is the position of hand wheel 6 when being in "on" position.Adorn a mounting panel 13 on the appropriate location of the framework 1 of switch cubicle, be fixed with little axle 14 on it, shielding plate 7 is fixed on the axle sleeve 15 of little axle, and axle sleeve 15 outer casing springs 8 are loaded onto behind the L shaped shielding plate fixing with split pin 16.One end hook of spring 8 hangs on the shielding plate 7, and the other end is stuck on the mounting panel 13.On switch cubicle door 2, with shielding plate 7 corresponding positions on adorn a jacking block 9.The structure of jam plate 5, latch hook 12 and locking bar 11 and the operating principle of mounting means and anti-misoperation apparatus and embodiment 1 are together.
