In order to solve because of high-tension switch cabinet rear door closure state lower electromagnet cannot the earthed switch that causes of normal reset can not the problem of normal running, we can arrange a set of manual electromagnet auxiliary reset mechanism, particularly, as Fig. 1, shown in Fig. 4, the below place that we can be positioned at electromagnet on support is fixedly installed the first rotating shaft 4, then a sheathed pivoted housing 41 in the first rotating shaft, a sheathed rotating disk 42 again outside pivoted housing, like this, pivoted housing can around the first axis of rotation, rotating disk can rotate around pivoted housing, that is, can relatively rotate between pivoted housing and rotating disk.We need on the upside of the periphery of rotating disk, arrange a fan-shaped spacing groove 421, this fan-shaped spacing groove radially extends internally until be communicated with pivoted housing, then we can radially arrange the poke rod 43 that is positioned at fan-shaped spacing groove in the side of pivoted housing, fan-shaped spacing groove is stretched out in poke rod outer end upwards, and a U-shaped shift fork 431 is set in the upper end of poke rod, meanwhile, the rearward end that the iron core of electromagnet stretches out coil needs to arrange a pin 33, and makes the U-shaped shift fork of poke rod block pin.Like this, when poke rod rotates, namely U-shaped shift fork moves forward and backward by the iron core of pin band motor magnet, and pin then moves in U-shaped shift fork.Certainly, in order to reduce frictional resistance, we also can on pin a sheathed bearing, thus make can form rolling friction between U-shaped shift fork and pin.
In addition, in order to control the rotation of poke rod, as shown in Figure 1, the right side that we also need be positioned at the first rotating shaft on support arranges the second rotating shaft 5 with the first shaft parallel, one end of second rotating shaft arranges radial first connecting rod 51, between first connecting rod end and rotating disk lower edge, arrange second connecting rod 52, wherein first connecting rod is fixedly connected with the second rotating shaft, and the two ends of second connecting rod are hinged with first connecting rod, rotating disk respectively.In addition, for the ease of controlling the rotation of the second rotating shaft outside high voltage control cabinet, as shown in Figure 5, we can arrange one in the position of cabinet 6 front of high-tension switch cabinet correspondence the second rotating shaft and unlock through hole 61, in the second rotating shaft, arrange a dismountable release lever 53 towards the one end unlocking through hole, this release lever stretches out and unlocks outside through hole simultaneously.Like this, by rotating release lever and rotatable second rotating shaft, and high-tension switch cabinet is when normally running, and can unload release lever, and the second rotating shaft is now hidden in high-tension switch cabinet inside, thus can avoid the improper rotation of the second rotating shaft.Further, as shown in Figure 1, the left side that we also need be positioned at the first rotating shaft on support arranges a pulley 11, rotating disk lower edge connects a stay cord 12, the other end of stay cord is walked around pulley left and is connected with a reset weight 13, thus make reset weight form a substantially invariable moment of torsion to rotating disk, the position limiting structure limiting dial rotation angle is set simultaneously on support, makes rotating disk have the extreme position in a left side and the extreme position on right side.
Because the utility model is by the action of reducible electromagnet locking earthed switch, therefore its structure is simple and be easy to control.When high-tension switch cabinet is when normally running at ordinary times, its back door is closed, and electromagnet is now in off-position, and as shown in Figure 2, iron core is in the retrogressing reset mode be separated with gangbar under the effect of rear end stage clip, and thus ground connection handle can regular event.Owing to having a running clearance between poke rod and the fan-shaped spacing groove of rotating disk, therefore, can relatively rotate between poke rod and rotating disk, like this, rotating disk is in the extreme position on right side under the effect of reset weight, and the limit, left side of poke rod now and fan-shaped spacing groove leans.
When the back door of high-tension switch cabinet is opened, the travel switch be arranged on back door makes electromagnet be energized, as shown in Figure 1, iron core now moves forward to the right, and correspondingly drives poke rod to turn to the right in fan-shaped spacing groove and lean with the right edge of fan-shaped spacing groove, and the locking end of rod nose blocks gangbar makes it cannot action downwards, gangbar is by locking, correspondingly, earthed switch akinesia, thus the personal safety that operating personnel can be guaranteed.
When the back door of high-tension switch cabinet is closed again, electromagnet is in off-position again, iron core moves to left back in the effect of rear end stage clip, and correspondingly drive poke rod in fan-shaped spacing groove to left pivot movement to leaning with the limit, left side of fan-shaped spacing groove, the locking end of rod nose is separated with gangbar and is in reset mode, and ground connection handle can recover regular event.If electromagnet now cannot retreat reset because of reasons such as clamping stagnations, release lever can be connected with the second rotating shaft through high-voltage switch gear unblock through hole cashier's office in a shop by we, then rotate release lever and make the second axis of rotation, as shown in Figure 3, namely second rotating shaft pulls second connecting rod by first connecting rod, and by second connecting rod, rotating disk is rotated to the left, now the right edge of the fan-shaped spacing groove of rotating disk can promote poke rod and rotates to the left, namely the U-shaped shift fork of poke rod end drives iron core to move reset afterwards to the left, the locking end of rod nose is made to be separated with gangbar and to be in reset mode, ground connection handle can recover regular event.Then, we can unload release lever, and like this, rotating disk turns right and is reset to the extreme position on right side under the effect of reset weight, and the limit, left side of poke rod now and fan-shaped spacing groove leans.
For the ease of controlling the rotational angle of rotating disk, as shown in Figure 4, position limiting structure of the present utility model comprises the arc-shaped limit groove 422 be arranged on rotating disk, this arc-shaped limit groove is concentric with the first rotating shaft, correspondingly, support is arranged a banking pin 14, banking pin screens is slidably in arc-shaped limit groove.Like this, when dial rotation, namely banking pin relatively moves along arc-shaped limit groove, when the screens of banking pin difference is when the two ends of arc-shaped limit groove, namely defines the rotational angle of the rotating disk left and right sides.
In order to increase reliability when release lever is connected with the second rotating shaft, as Fig. 6, shown in Fig. 7, we can be connected one end in the second rotating shaft end face with release lever arranges an annular slot 54, annular slot has inside and outside two sides, correspondingly, release lever 53 comprises a linkage section 531 and the rotational segment 532 vertical with linkage section rear end, thus make release lever L-shaped, the front end of linkage section arranges pluggable collar 55 in annular slot, collar has inside and outside two sides equally, like this, when release lever is connected in the second rotating shaft by needs, can by the linkage section of release lever through high-voltage switch gear unblock through hole cashier's office in a shop, the collar on linkage section is made to be plugged in the annular slot of the second rotating shaft, the second rotating shaft synchronous axial system can be made when now rotating release lever.Certain annular slot can not adopt cirque structure, and particularly, the inner side edge of annular slot is regular hexagon, thus forms the structure of a similar hex screw head, and the outer side edges of annular slot is made up of the regular hexagon at two 30 degree of angles that misplace coaxially.Correspondingly, the collar outer side edges of linkage section is regular hexagon, and suitable with the misplace regular hexagon arranged of annular slot outer side edges, thus forms the structure of a similar hex screw head; The inner side edge of collar is made up of the regular hexagon at two 30 degree of angles that misplace coaxially, and the regular hexagon size of its regular hexagon size and annular slot inner side edge is suitable.When the collar of release lever inserts in the annular slot of the second rotating shaft, inside and outside two sides of collar are engaged with inside and outside two sides of annular slot simultaneously, thus can transmit larger moment of torsion.Particularly, we can arrange larger fit clearance between collar and annular slot, so that collar is inserted in annular slot.Because inside and outside two sides of collar are engaged with inside and outside two sides of annular slot simultaneously, therefore when collar and annular slot produce offset time, gap between the side of annular slot outer side edges and collar outer side edges can increase, meanwhile, gap between annular slot inner side edge phase the same side and the inner side edge of collar can correspondingly reduce, thus make the stability maintaining cooperation between collar and annular slot on the whole, to transmit the stable moment of torsion of a size, avoid occurring skidding while being convenient to insert.And the above-mentioned special connecting structure of collar and annular slot can avoid non-working person to utilize general utility tool to carry out improper unblock.
