Abstract
The utility model relates to a teaching aid for exercising back break operation and fault reclosing. The utility model is provided with a programmable controller whose output end is provided with an AC contactor and whose input end is provided with a universal switch, a reclosing locking and reset switch circuit and a simulation switch circuit for protection actions. The utility model can be used for any fault simulation operation exercises of closing trip, reclosing return throw of a circuit breaker, and can also be directly used for the control operation of a high-voltage circuit breaker in production, having obvious effect on improving the reclosing success ratio.
Description
The utility model belongs to the manoeuvre teaching aid that manoeuvre teaching aid, particularly grid switching operation and fault simulation and automatic reclosing are used in education.
Be transported to the relevant course of electricity, especially learning in the courses such as generating plant, transformer station's electrical equipment, relay protection, Power System Automation Equipment in study, because the shortage of operation manoeuvre teaching apparatus makes the religion word of these courses relatively more difficult.Especially back brake and fault reclosing operation, they occur not really frequently in distribution operation, but but very important, no matter be the student in school or on-the-job workman, all fewer in the on-the-spot chance of being familiar with of distribution.At this situation, the utility model aims to provide the manoeuvre teaching aid of a kind of energy simulated high-pressure isolating switch control system work, and the workman of student and training just can be familiar with and the operation of back brake and fault reclosing on top of by means of teaching aid.
The utility model is to realize its purpose like this: a PLC programmable controller of having imported certain program is housed in the casing in this teaching aid; there are the A.C. contactor of simulated high-pressure isolating switch, input end that the switching circuit and the protection action simulation switching circuit of the locking and the involution of universal seclector, reclosing are arranged at its output terminal.Wherein, protection action simulation switching circuit has the button of three sections short troubles of simulation; Realize automatic reclosing with the simulation of PLC Programmable Logic Controller.
What the utility model can carry out isolating switch arbitrarily closes, jumps the operation manoeuvre, and its light acoustics has on-the-spot true feeling; There are three kinds of protections to move, can carry out reclosing arbitrarily and move back fault simulation operation manoeuvre when throwing in the analog functuion and the automatic reclosing of tripping operation; And the time of the protection action of can adjusting as required, reclosing starting, coincidence preacceleration or after-acceleration; And because the A.C. contactor of this device can be used for driving the combined floodgate and the tripping operation coil of wire of primary cut-out, thereby this device can be used for producing the control operation of the primary cut-out in the reality, can also improve the reclosing success ratio effectively.In addition, this teaching aid has also that volume is little, in light weight, the advantage of little power consumption.
Embodiment further specifies the utility model below in conjunction with accompanying drawing:
Fig. 1 is the synoptic diagram of this grid switching operation and fault reclosing demonstration teaching aid.
Fig. 2 is the circuit diagram of this grid switching operation and fault reclosing demonstration teaching aid.
19 is casings among the figure, PLC Programmable Logic Controller 18 is arranged in the casing, on the panel 20 1,2,3 is respectively one, two, three sections short trouble buttons, when A.C. contactor 12 is in closing position, universal seclector 6 is in when closing a floodgate the position, back: press above-mentioned button just respectively analog line one section or two sections or three sections short troubles have taken place, this moment, A.C. contactor 12 simulated high-pressure isolating switchs opened circuit, the automatic reclosing action, pilot lamp 9 is luminous, be in blocking after the action once of expression reclosing, if reclosing success, the automatic involution of reclosing after 15～20 seconds, pilot lamp 9 extinguishes.If reclosing is unsuccessful, pilot lamp 9 is luminous always, until artificially universal seclector being reset to position, tripping operation back.If need the ahead relieving locking, press reclosing involution button 4 and get final product.If need reclosing not work, can move to move back and throw switch 5.Press button 1 or 2 or 3 the time when instantaneous, transient fault has taken place in analog line; When pressing one of above-mentioned button for a long time, permanent fault has taken place in analog line.When the position of A.C. contactor 12 and universal seclector 6 corresponded to the state of on-off respectively, red light 8 or green light 7 sent zero diopter respectively, seasonable this two lamp were not promptly sent out flash of light respectively.The 11st, the combined floodgate pilot lamp, the 14th, portable, the 15th, supply socket, the 16th, simulate closing by hand button on the spot, the 17th, bus.Line side disconnecting link 13 and bus bar side disconnecting link 10 are simulated actual line side and bus bar side disconnector respectively, use for the grid switching operation demonstration.Realize automatic reclosing by 18 simulations of PLC Programmable Logic Controller.In Programmable Logic Controller PLC, have the eeprom chip of having stored control program.When only simulating a primary cut-out job, adopting one has 5 input points, and the PLC Programmable Logic Controller of 4 output points is just passable.If adopt when the Programmable Logic Controller of more outputs and input point is arranged, then can simulate (or control) a plurality of isolating switchs simultaneously, this moment, the control program of this simulation teaching aid can design by modular structure, the controlling ladder program of each primary cut-out all is a standalone module, and wherein the reclosing working routine is again as a submodule.Under switch corresponding with circuit breaker position to non-fault analog case, PLC only scans and carries out primary cut-out and whether operation is arranged and the not discriminating program of fault simulation is arranged.If have, then control module and reclosing operational module are carried out in scanning; If there is not then redirect.Owing to adopted this measure, the PLC scan period accelerated by module redirect control.
For example, when use has 16 output points, during the Programmable Logic Controller of the EX-40PLC of 24 input points, as produce a public flash of light source output by PLC, and red, the green pilot lamp of each isolating switch is flat, when flash of light realizes by hard wired logic, can the maximum centralized control that realizes 6 isolating switchs.
