Description
Technical field
The utility model relates to a kind of position detecting device of protecting pressing plate, relates in particular to the input and the pick-up unit that withdraws from the position of protecting electrical power system cabinet center platen.
Background technology
In power protection system, need at present to use a large amount of pressing plates, be used for being switched on or switched off of guard signal.The state acquisition of existing pressing plate much realizes that to on-the-spot checking there is the human and material resources consumption problem in this mode by managerial personnel on the spot, also has the very big possibility of makeing mistakes simultaneously.At a small amount of automatic acquisition mode of using of pressing plate of electric system,, exist complexity, long construction period, the problem such as difficult in maintenance of installing because its design is unreasonable.
Summary of the invention
At the problem that present protection pressing plate state acquisition exists, the utility model provides a kind of device that can detect the pressing plate state by contactless sensing technology, and for achieving the above object, technical solution adopted in the utility model is:
This device comprises that pressing plate in flakes, the pressing plate seat, position inspection support and magnet steel post, pressing plate is located in flakes above the pressing plate seat and with the pressing plate seat and realizes being electrically connected, fixedly connected with the end face of position inspection support in the seat end of pressing plate seat, pressing plate fixed bar in flakes passes the pressing plate seat downwards successively fixedlys connected with the magnet steel post with position inspection support, be with the back-moving spring that is connected between pressing plate seat and the magnet steel post on the pressing plate fixed bar in flakes, be fixed with socket communication on the position inspection support, socket communication is by data line fixedly connected input state Hall element and exit status Hall element, the cylinder of magnet steel post is provided with magnet steel, when pressing plate is in the input position, input state Hall element is aimed at magnet steel, when pressing plate is in when withdrawing from the position, the exit status Hall element is aimed at magnet steel.
Position inspection frame bottom is stamped rack plate.
Hall element is realized state-detection with cooperating of magnet steel, and when pressing plate was the input state, magnet steel was aimed at and dropped into state sensor; When pressing plate was exit status, magnet steel was aimed at the exit status sensor, and the transducing signal of Hall element passes to control system by socket communication, and control system is judged the pressing plate state in view of the above.
Therefore the utility model can be with the whole robotizations of the position probing of pressing plate, and the positional information that collects accurately, reliably greatly improves the automatic management degree of transformer station.This device has rational in infrastructure, and testing result is characteristics accurately and reliably.
Description of drawings
Fig. 1 is a STRUCTURE DECOMPOSITION synoptic diagram of the present utility model;
Fig. 2 is in the structural representation that drops into the position for the pressing plate of utility model;
Fig. 3 is in the structural representation of position of rotation for practical new pressing plate.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further:
As shown in Figure 1, it is that protection screen panel of the present utility model is installed that panel 3 is installed, and above it a plurality of pick-up units can be installed.Pressing plate 1 is pressed against above the pressing plate seat 2 and with pressing plate seat 2 and realizes being electrically connected in flakes, and the fixed leg of pressing plate seat 2 passes two mother rib lateral rotundums that panel 3 is installed, and examines the end face both sides of support 5 by the nut fixed bit.1 fixed bar passes the middle circular hole of pressing plate seat 2, installation panel 3 downwards to pressing plate successively in flakes, the inside cylindrical cavity of position inspection support 5 is fixedlyed connected with magnet steel post 8, magnet steel post 8 is fixed on pressing plate 1 fixed bar bottom in flakes, can follow pressing plate and 1 finish together and action such as pull out, rotate, put back in flakes.Pressing plate is with on 1 the fixed bar in flakes can make pressing plate 1 back-moving spring that resets 4 in flakes, and this back-moving spring 4 is connected between pressing plate seat 2 and the magnet steel post 8, and is positioned at an inner space of inspection support 5.Socket communication 6 is filled in the inspection support 5 that puts in place along rectangular channel, and outside mounting bracket cover plate 7 is also fastening with screw, and socket communication 6 adopts six core telephone line sockets, is used to the communication cable of pegging graft, and the signal that collects is transferred to control system.Socket communication 6 is by the fixedly connected input state of data line Hall element 8 and exit status Hall element 9, the cylinder of magnet steel post 8 is provided with magnet steel 11, when pressing plate is in the input position, input state Hall element 8 is aimed at magnet steel 11, when pressing plate is in when withdrawing from the position, exit status Hall element 9 is aimed at magnet steel 11.
Fig. 2 and Fig. 3 course of work of the present utility model (pressing plate withdraws from by putting into) synoptic diagram is clearer expression matching relationship, has omitted position inspection support and rack plate among the figure.
As shown in Figure 2, when pressing plate was in the input position, the magnet steel 11 on the magnet steel post 8 was aimed at input state Hall elements 9, and control system judges that in view of the above pressing plate is in the input position.
As shown in Figure 3, when pressing plate begins to switch, pressing plate is in flakes 1 when being drawn out, magnet steel post 8 is pulled out by one, magnet steel 11 departs from input state Hall element 9, this moment, magnet steel 11 was not promptly aimed at input state Hall element 9, did not aim at exit status Hall element 10 yet, and control system judges that in view of the above pressing plate is in the crossover position between dropping into and withdrawing from; When pressing plate in flakes 1 rotation and put back to after, magnet steel 11 is also followed magnet steel post 8 and is rotated together and put back to, this moment, magnet steel 11 was aimed at exit status Hall elements 10, control system is judged in view of the above that pressing plate is in and is withdrawed from the position.
