Description
Technical field
The utility model relates to a kind of Experiment Training system, particularly a kind of experimental provision of analog ligand grid automation.
Background technology
Distribution automation system makes a kind of automated system that can make distribution enterprise monitor, coordinate and operate in the distance controller switching equipment with real-time mode.The distribution network automated automation of transformation substations and feeder automation two parts of comprising.Feeder automation is exactly the distant place method of operation that monitors feeder line, after fault occurs, and definite fault section promptly and accurately, isolated fault section recovery perfect the feeder automation of district's power supply rapidly.Therefore distribution automation system is difficult to move into laboratory, Training Room and not only invests greatly, and the safety problem that high pressure causes is also very outstanding.
This project is passed through analogy method, reproduce distribution network automated process, the sensation that allows student be in the action, not only can further deepen the understanding to professional knowledge and merge to connect, prior creativity consciousness and innovation ability of cultivating student, is conducive to the culturing innovative talent significantly.
Utility model content
The purpose of this utility model is the deficiency in order to solve above-mentioned technology and the experimental provision of the analog ligand grid automation of the accurate analog ligand grid automation of a kind of energy process is provided.
In order to achieve the above object, the experimental provision of the designed analog ligand grid automation of the utility model, it comprises bus, automatic circuit and sectionaliser composition, the order of connection that it is characterized in that described bus, automatic circuit and sectionaliser is bus A, automatic circuit C, sectionaliser E, sectionaliser G, sectionaliser H, sectionaliser F, automatic circuit D and bus B, wherein sectionaliser G is the interconnection switch in normally open, all the other described sectionalisers are the block switch in normally off, are provided with simulation short trouble switch dk between sectionaliser E and sectionaliser G.The feature of this structure is by bus, automatic circuit and sectionaliser analog ligand electrical network automatic environmental.
In order further to improve experiment effect and conspicuousness, on described bus and sectionaliser, be all connected with switch and pilot lamp.
In the utility model, described automatic circuit is a kind of switchgear from tool control and defencive function, and it can cut-off and coincidence order is cut-off and the operation that overlaps automatically by predetermined, and is automatically reseting thereafter or locking.
Described sectionaliser is that one coordinates with mains side prime switch, the switchgear of automatic brake separating in decompression or currentless situation.When occurring when permanent fault, sectionaliser after point closing operation of pre-determined number locking in gate-dividing state, thereby reach the object of isolated fault track section.Sectionaliser adopts voltage--time type sectionaliser, and it is to rely on the time length of pressurization, decompression to control its action, and separating brake after decompression, closes a floodgate into locking after pressurization.Voltage--time type sectionaliser has two important parameters to adjust; One is the x time limit, and it refers to from sectionaliser mains side and is forced into the time delay that this segmentation is closed a floodgate; Another parameter is the y time limit, and it is called again failure detection time, and its implication is: if sectionaliser close a floodgate after within the time that does not exceed the y time limit decompression again, this sectionaliser separating brake be latched in gate-dividing state, until next time again also automatic reclosing no longer when electric.
Meanwhile, voltage--time type sectionaliser generally has two cover functions.A set of is towards the block switch in normally off; Another set of is the interconnection switch being applied in normally open.This two covers function can be switched by an operating grip.
The experimental provision of the analog ligand grid automation that the utility model obtains, pass through analogy method, reproduce distribution network automated process, the sensation that allows student be in the action, not only can further deepen the understanding to professional knowledge and merge to connect, prior creativity consciousness and innovation ability of cultivating student, is conducive to the culturing innovative talent significantly.
Accompanying drawing explanation
Fig. 1 is the experimental provision structural representation of the analog ligand grid automation that obtains of the utility model.
Embodiment
Below by embodiment, the utility model will be further described by reference to the accompanying drawings.
Embodiment 1:
The experimental provision of the analog ligand grid automation that the present embodiment is described, it comprises bus, automatic circuit and sectionaliser composition, the order of connection that it is characterized in that described bus, automatic circuit and sectionaliser is bus A, automatic circuit C, sectionaliser E, sectionaliser G, sectionaliser H, sectionaliser F, automatic circuit D and bus B, wherein sectionaliser G is the interconnection switch in normally open, all the other described sectionalisers are the block switch in normally off, are provided with simulation short trouble switch dk between sectionaliser E and sectionaliser G.On described bus and sectionaliser, be all connected with switch and pilot lamp.
When experiment, each equipment arranges as follows: automatic circuit C, D adjust as every other one fast, and be 15S the time of coincidence for the first time, and be 5S the time of coincidence for the second time.Sectionaliser E, F, H adopt voltage one time type sectionaliser, and are arranged on first set function, and their X time limit expansion is decided to be 7s, and y time limit expansion is decided to be 5s; Sectionaliser G also adopts voltage one time type sectionaliser, but is arranged on the second cover function, and its X time limit expansion is decided to be 45s, and y time limit expansion is decided to be 5s.
Experiment while carrying out according to following steps:
1. normally operation, closes successively except the switch of all devices of simulation short trouble dk, and all pilot lamp are bright, disconnected in sectionaliser G punishment, observation partition running situation.
2. the dK that closes a switch, at 2 districts' simulation short troubles.Occur after permanent fault in 2nd district, automatic circuit C tripping operation, causes interconnection switch left side circuit decompression, causes sectionaliser E separating brake, and starts the X of sectionaliser G
lcounter; After emergency stop valve trip 15s, automatic circuit C overlaps for the first time, again after the X time limit of 7s, sectionaliser E automatic closing, now because 2nd district exist permanent fault, causes automatic circuit C tripping operation again, thereby circuit decompression, cause the equal separating brake of sectionaliser E, because sectionaliser E does not reach just decompression again of y time limit (5s) after closing a floodgate, this sectionaliser will be blocked; Pass through again 5S, automatic circuit C overlaps for the second time, because sectionaliser E is because locking keeps gate-dividing state, electricity is supplied to 1 section; Automatically by localization of fault and isolate.
3. observe the isolation and restoration (pilot lamp variation) of fault in feeder automation, after automatic circuit C trips for the first time, through the X of 45s
lafter time limit, sectionaliser G automatic closing, now because 2 sections there is permanent fault, cause the automatic circuit D tripping operation of the circuit on interconnection switch right side, thereby right side circuit decompression, cause the equal separating brake of all sectionalisers on it, because sectionaliser G does not reach just decompression again of y time limit (5s) after closing a floodgate, this sectionaliser will be blocked; The sectionaliser on interconnection switch and right side and automatic circuit close a floodgate again in order, and sectionaliser G keeps gate-dividing state because of locking, thereby have isolated fault 2 sections, have recovered to perfect section power supply.
