Existing relay protection of power system comprehensive experiment table, can be according to experimental real-training content generally using box structure is hung It needs to be combined.Bench top includes the power supply control flow for being set to left side, is set to intermediate and right side extension case suspension Area, what it is in the areas Gua Xiang is the experiments component such as power supply and pressure regulator, resistor below, can be selected according to different experimental projects Different extension casees, sets that there are two drawers in the middle part of experimental bench, and lower part is storeroom.
Include several pin spliced eyes for being connected with component's feet, identical in each extension case suspension area It hangs in area or different suspension areas, grafting connection is carried out by grafting conducting wire, realizes the structure of circuit;But it is put in experimental bench During setting, environmentally there is the placement requirement without apparent dust to placing, otherwise grafting hole inside ash, easy component draw Resistance on foot becomes larger, and leads to the inaccuracy of measurement data, and also bad cleaning.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of relay protection of power system is comprehensive Experimental bench is closed, the probability of pin spliced eye dust stratification can be reduced.
The above-mentioned technical purpose of the utility model technical scheme is that:
A kind of relay protection of power system comprehensive experiment table, if including the cladding case of practical traning platform and setting practical traning platform top, Several pin spliced eyes are provided on the extension case, if be provided on the practical traning platform it is coupled for cover cladding case to prevent The only gear ash component of pin spliced eye dust stratification.
So set, being blocked to the pin spliced eye on practical traning platform by keeping off grey component, places dust and inserted in pin Interior deposition is connect, the probability of pin spliced eye dust stratification is reduced with this, ensures the accuracy of data in experimentation, while avoiding product Ash leads to badly-cleaned problem.
Further preferably:The grey component of gear includes curtain for blocking pin spliced eye and is set to real training Winding part on platform for receiving anti-curtain.
So set, carrying out folding and unfolding to curtain by winding part, dust, reduction pin are blocked being played to pin spliced eye While spliced eye dust stratification probability, operate also simple and convenient.
Further preferably:The winding part includes being rotatably installed on practical traning platform for winding the cloth winding rod of curtain, setting It is placed on practical traning platform and drawing bar and be connected with curtain and extend around the traction for drawing bar bottom end down below cloth winding rod Rope.
So set, when needing to put down curtain, traction rope, traction rope is pulled to be pulled on cloth winding rod around bar is drawn Curtain, curtain releases and moves down from cloth winding rod, blocked to pin spliced eye, and being played with this reduces pin grafting The effect of the probability of hole dust stratification.
When needing winding curtain to be tested, when having certain dust on curtain, can be wiped by rag, Except dust, cloth winding rod is then rotated, curtain is wound onto on cloth winding rod, and curtain is opened with this, is exposed pin spliced eye and is carried out Experiment, it is easy to operate.
Further preferably:Rotation is provided with the distaff for winding traction rope, the distaff on the practical traning platform On be provided with for driving it to rotate and limiting its counter-rotational locating part.
So set, by the driving of locating part, drive distaff rotation so that traction rope on distaff, and And locating part has the limitation counter-rotational effect of distaff, can ensure that traction rope is in the state tensed, i.e. curtain will not It loosens, keeps pushing against with practical traning platform, improve the connection sealing of curtain and practical traning platform, reduce the entrance of dust, dropped with this The probability of low pin spliced eye dust stratification.
Further preferably:The practical traning platform both sides are both provided with traction rope.
So set, being respectively provided with traction rope by practical traning platform both sides, i.e., during distaff rotates, curtain both ends are all It is pushed against with practical traning platform so that the connection sealing of curtain and practical traning platform is more preferable, further decreases the probability of pin spliced eye dust stratification.
Further preferably:The locating part includes the worm gear being set on cloth winding rod and is rotatably installed in practical traning platform Worm screw that is upper and being meshed with worm gear, described worm screw one end is pierced by practical traning platform.
So set, need to pull down curtain pin spliced eye is blocked when, be located at outside practical traning platform by rotation Worm screw drives worm gear rotation, drives distaff rotation so that traction rope is on distaff, positioned at leading for practical traning platform both sides Messenger pulls curtain to move down, and pin spliced eye is blocked cleaning to prevent dust stratification, and match and close worm gear and worm screw limitation Counter-rotational characteristic enables to traction rope to be constantly in the state of tension, ensures the connection sealing of curtain and practical traning platform.
When needing to pack up curtain, worm screw is rotated backward, the traction rope of discharge section length then rotates cloth winding rod, makes Curtain is obtained on cloth winding rod, the collection technique purpose of curtain is reached with this.
Further preferably:The curtain is identical with the coiling direction of traction rope, the cloth winding rod and distaff end part It is not provided with intermeshing first gear and second gear.
So set, when due to curtain to be packed up, rotary worm successively and cloth winding rod are needed, it is troublesome in poeration, pass through setting First gear and second gear can control the rotation of cloth winding rod by rotary worm, improve working efficiency.
Further preferably:The curtain is set as ventilation dustproof material.
So set, being set as ventilation dustproof material by curtain, while reaching dust-proof effect, it can ensure curtain The flowing of the cavity and extraneous air that are formed with practical traning platform, plays the role of cooling.
In conclusion the utility model having the beneficial effect that in contrast to the prior art:By the driving of worm screw and worm screw, and And with first gear and second gear is closed, the rotation of distaff and cloth winding rod can be driven simultaneously, it is only necessary to which rotary worm is just The folding and unfolding that curtain may be implemented, while realizing dust-proof probability to reduce pin spliced eye dust stratification, operation is also simple and convenient.
