The beneficial effects of the utility model are: under the situation of reaching the spot without personnel, can carry out the isolated operation that stops sending electricity, circuit, the telemonitoring of line current voltage, route protection tripping operation information, the uploading of capacity of idle power etc. of gaining merit of high-tension line whenever and wherever possible.Easy to operate, quick, safety are not subjected to weather effect.Running state information is in time comprehensive.
Four, description of drawings:
Accompanying drawing 1 is an operation principle block diagram of the present utility model;
Accompanying drawing 2 is primary connection schematic diagrams of the present utility model.
Five, embodiment:
In conjunction with the accompanying drawings 1 and 2, the utility model will be further described:
With reference to accompanying drawing 1, the utility model is mainly controlled unit 5 five major parts by remote control vacuum switch unit 1, remote control Disconnecting switch unit 2, power control unit 3, GPRS communication unit 4 and computer backstage and is formed, a connect side of manual isolating switch of power circuit, manually the opposite side of isolating switch connects remote control vacuum switch unit 1 and remote control Disconnecting switch unit 2, be provided with dedicated potential transformer in the remote control vacuum switch unit 1 and power supply be provided for power control unit 3 and GPRS communication unit 4, give the charge in batteries of GPRS communication unit 4 simultaneously; Remote control vacuum switch unit 1 is connected power control unit 3 respectively with remote control Disconnecting switch unit 2, realizes combined floodgate, separating brake by power control unit 3, and power control unit 3 is controlled unit 5 by connection GPRS communication unit 4 with the computer backstage and communicated by letter.
Wherein, remote control vacuum switch unit 1 is made up of novel high-pressure vacuum switch, dedicated potential transformer, current transformer, meritorious wattless component watt-hour meter, protection module etc.; Remote control Disconnecting switch unit 2 is made up of electric isolating switch, motor-operating mechanism, linkage etc. on the light moment post; Power control unit 3 is made up of power supply adaptor, battery, relay control module etc.; GPRS communication unit 4 is made up of GPRS communication module, input/output module, antenna etc.; The computer backstage control unit 5 by microcomputer, special use control background program, mobile phone is formed.
Concrete primary connection such as accompanying drawing 2: power circuit is installed one group of manual isolating switch earlier, and this isolating switch generally is in and closes the position.It mainly acts on is when the maintenance unit switch, plays insulating power supply.Manually the isolating switch downside is installed remote control vacuum switch unit 1 of the present utility model, plays circuit is carried out operation monitoring, electric energy control, stops sending electric control and error protection effect.Remote control vacuum switch unit 1 downside is installed remote control Disconnecting switch unit 2 of the present utility model, and circuit is played the remote control buffer action, can an obvious cut-off point be arranged with power circuit when line maintenance.
The utility model groundwork principle is: the dedicated potential transformer in the remote control vacuum switch unit 1 provides power supply for power control unit 3 and GPRS communication unit 4, can also give the charge in batteries of GPRS communication unit 4 simultaneously.When circuit (electrical network) had a power failure, the storage battery electric energy provided electric energy for power control unit 3, GPRS communication unit 4, circuit is carried out once branch, the closing operation of Stateful Inspection and vacuum switch.Information such as the electric current that remote control vacuum switch unit 1 is gathered, voltage, power factor, running status, electric weight, signal send to the computer backstage by GPRS communication unit 4 real-time (or regularly) and control unit 5.The computer background program is circuit electric current, magnitude of voltage and unit switch running status in real time.And according to uploading load, voltage curve and meritorious, the capacity of idle power statistical form that data can form this circuit.Unit 5 is controlled on the computer backstage can send combined floodgate, separating brake instruction, and instruction comes steering maneuver control unit 3 by GPRS communication unit 4, changes the running status of high-voltage switch gear (isolating switch).Thereby reach the purpose of Long-distance Control.
Remote control vacuum switch unit operation principle: this unit is equipped with the energy storage type high-pressure vacuum switch, and the 220V power supply that is provided by dedicated potential transformer under the normal condition is to the switch energy storage.Energy storage once can once divide under power-off condition, closing operation.When switch switching signal of GPRS communication unit was given in unit, computer backstage, GPRS communication module unit triggers power control unit 3 made the action of switch closing relay, connects the closing circuit of energy storage vacuum switch, makes the closing coil energising, and switch closes a floodgate.Close a floodgate the back by auxiliary contact control GPRS communication unit, send to the closing position signal in computer backstage.The separating brake principle is the same.
Remote control Disconnecting switch unit operation principle: this unit is the light moment isolating switch of motor-operating mechanism, and operating voltage is direct current 220V.During combined floodgate, isolating switch switching signal of GPRS communication unit is given in unit, computer backstage, GPRS communication module unit triggers power control unit 3, make the action of isolating switch closing relay, give the direct voltage of one+220V of isolator operation motor, operating electrical machines just changes, and by linkage isolating switch is closed a floodgate.By the closing relay of position contact opening operation motor, close a floodgate and finish after combined floodgate puts in place.The closing position contact is controlled the GPRS communication unit simultaneously, sends to the closing position signal in computer backstage.During separating brake, isolating switch sub-gate signal of GPRS communication unit is given in unit, computer backstage, GPRS communication module unit triggers power control unit 3, make the actuating of relay of isolating switch separating brake, give the direct voltage of one-220V of isolator operation motor, the operating electrical machines counter-rotating makes the isolating switch separating brake by linkage.By the separating brake relay of position contact opening operation motor, separating brake finished after separating brake put in place.Separating brake position contact is controlled the GPRS communication unit simultaneously, sends to the separating brake position signalling in computer backstage.
