Abstract
The utility model discloses an in right side wall that high tension switchgear earthing switch prevents mistake operating means, draw back plate can pass protection box inserted protection box, the rear end of pivot was passed long chute and is fixed on the left side position of draw back plate, and the pivot removes about can following long chute, and the left end of spring is fixed in the rear end of pivot, and its right -hand member is fixed on the protection box antetheca, the utility model has the characteristics of simple structure, safe and reliable, easily installation, can prevent effectively that earthing switch from preventing the maloperation.
Description
Technical field
This utility model relates to a kind of earthed switch anti-misoperation apparatus.
Background technology
High-voltage switch cabinet grounding switch is sometimes for electronic and manual, when requiring earthed switch electric operating, does not allow manual operation simultaneously, it is desirable to do not allow electric operating during manual operation.
Summary of the invention
For achieving the above object, this utility model provides a kind of high-voltage switch cabinet grounding switch anti-misoperation apparatus, and its technical scheme taked is:
Including protection box, draw back plate, latching electromagnet, pivot pin and spring, latching electromagnet is fixed in protection box, the pin of latching electromagnet can move up and down, draw back plate is " L " shape that left side is prominent, draw back plate may pass through the right side wall of protection box and inserts in protection box, long chute is had on the antetheca of protection box, the rear end of pivot pin is fixed in the leftward position of draw back plate through long chute, pivot pin can move left and right along long chute, spring is located in protection box, the left end of spring is fixed on the rear end of pivot pin, and its right-hand member is fixed on protection box antetheca；When the pin of latching electromagnet extends downwardly from, the left end of draw back plate is positioned at the right side of pin, and draw back plate left part is positioned at protection box, and pivot pin is positioned at the right-hand member of long chute, and spring is in nature compressive state.
When latching electromagnet must not electricity time, i.e. the pin of latching electromagnet stretches out, it is impossible to is pulled draw back plate by pivot pin to the left, now can only carry out the electric operating of earthed switch；When latching electromagnet obtains electric, the i.e. pin of latching electromagnet obtains electric adhesive, draw back plate can be pulled to the left by pivot pin, spring is tightened up simultaneously, and ground cutter operates big axis hole and exposes, and now can carry out the manual operation of earthed switch, after ground cutter handle manually completes extraction, draw back plate can under spring tension effect auto-returned original position, block ground cutter big axle handle hole, it is achieved can not arbitrarily operate pass operation handle insert ground connection big axle handle hole.
High-voltage switch cabinet grounding switch (electronic and manual) anti-misoperation is protected by this utility model effectively, has simple in construction, feature safe and reliable, easy-to-install.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in detail.
As shown in Figure 1, latching electromagnet 3 is fixed in protection box 1, the pin of latching electromagnet 3 can move up and down, " L " shape that draw back plate 2 is prominent in left side, draw back plate 2 may pass through the right side wall of protection box 1 and inserts in protection box 1, long chute 6 is had on the antetheca of protection box 1, the rear end of pivot pin 4 is fixed in the leftward position of draw back plate 2 through long chute 6, pivot pin 4 can move left and right along long chute 6, spring 5 is located in protection box 1, the left end of spring 5 is fixed on the rear end of pivot pin 4, and its right-hand member is fixed on protection box 1 antetheca.
When latching electromagnet 3 must not electricity time, the i.e. pin of latching electromagnet stretches out, the left end of draw back plate 2 is positioned at the right side of pin, draw back plate 2 left part is positioned at protection box 1, pivot pin 4 is positioned at the right-hand member of long chute 6, spring 5 is in nature compressive state, now cannot pull draw back plate 2 to the left by pivot pin 4, now can only carry out the electric operating of earthed switch.When latching electromagnet 3 obtains electric, the i.e. pin of latching electromagnet 3 obtains electric adhesive, draw back plate 2 can be pulled to the left along long chute 6 by pivot pin 4, spring 5 is tightened up simultaneously, draw back plate 2 is integrally located in protection box 1, the big axis hole of now cutter operation exposes, the manual operation of earthed switch can be carried out, after ground cutter handle manually completes extraction, draw back plate 2 meeting auto-returned original position under spring 5 pulling force effect, make draw back plate 2 be exposed at the part outside protection box 1 and block ground cutter big axle handle hole, it is achieved can not arbitrarily operate.
