Wherein promptly stop the contact loop and be parallel with a change over switch at isolating switch.
Remote control of the present utility model only need simply be changed centralized operation case control loop and can realize straighforward operation, and the operations staff stands in safe position and presses remote controller and get final product during operation, and is easy and simple to handle, and need not drop into great amount of manpower.
Description of drawings
Accompanying drawing 1 is simplified electric control theory (is example mutually with A) for centralized operation control cabinet in the background technology;
Accompanying drawing 2 is simplified electric control theory for having installed centralized operation control cabinet of the present utility model additional;
Accompanying drawing 3 is circuit theory diagrams of the present utility model.
Embodiment
Come the utility model is described in further detail below in conjunction with accompanying drawing:
Be illustrated in figure 1 as isolating switch control principle figure:
1, closes a floodgate, when circuit breaker DL is dividing, ground connection disconnecting link GD is dividing, and presses switch knob HA this moment, the charged excitation of closing relay HJ coil, its normal opened contact HJ1 action and self-sustaining, normal opened contact HJ2 starter motor loop, isolating switch begins to close a floodgate, after being incorporated into the position, isolating switch travel switch CK1 disconnects, and HJ returns, and making process is finished.
2, separating brake, when circuit breaker DL is dividing, ground connection disconnecting link GD is dividing, and presses switch knob TA this moment, the charged excitation of separating brake relay FJ coil, its normal opened contact FJ1 action and self-sustaining, normal opened contact FJ2 starter motor loop, isolating switch begins separating brake, after separating brake puts in place, isolating switch travel switch CK2 disconnects, and FJ returns, and the separating brake process is finished.
3, promptly stop, if minute, meet accident in the making process, when pressing the JTA button, the JTA normally closed contact disconnects, HJ or FJ loss of excitation return, operating process stops.
According to above control principle, the utility model proposes a kind of remote control, and utilize the make contact of output relay YKJ1 and YKJ2 to replace HA and TA, the YKJ3 normally-closed contact is serially connected with the JTA loop, utilize a reflector, a receiver to carry out point-to-point instruction transmitting-receiving, utilize a microprocessor that YKJ1, YJK2 and YKJ3 are controlled again, by interface socket JK relay tip is inserted the isolating switch control loop then, can realize straighforward operation like this this isolating switch.
For realizing can straighforward operation, again can local operation, can realize easily on the spot/remote control conversion operations mode promptly stopping the contact loop and connect one on the spot/remote control change over switch ZK.
Operation principle of the present utility model is as follows:
1, form: generally should be made up of instruction reflector, command receiver, arithmetic control unit (microprocessor), relay assembly and interface module, microprocessor is the core component of this device.
When 2, substation isolating-switch is operated fail safe and reliability all there are very high requirement, must meet the demands with the remote controller of accepting instruction, the interference free performance of receiver so be used for firing order.The developing into us strong technique guarantee be provided of singlechip technology, with the single-chip microcomputer is that core has very high interference free performance based on reflector and the receiver that digital coding designs, its application relates to all trades and professions such as Aero-Space, telecom communication already, and its fail safe and reliability needn't be doubted.
Emitting head with receive head: F05P emitting head frequency stability 10-5 (frequency stabilization of sound table), working temperature-40 ℃-+60 ℃, volume 9 * 21 * 5mm (wide * long * thick).Because its transmitting carrier frequency is 315MHZ, operating frequency need not to apply for frequency in ISM band during use.J04V receives a receiving sensitivity-90db, demodulator filter bandwidth 10K, and dateout level Transistor-Transistor Logic level, noiseless output, working temperature-40 ℃-+60 ℃, volume 10 * 23 * 5mm is fit to and the supporting use of single-chip microcomputer.So reflector and receiver can select for use F05P low-power consumption emitting head and J04V low-power consumption to receive head, its high error-correcting channel coding techniques has very high antijamming capability, reliability can be guaranteed, and 3050 meters of its effective receiving ranges, can satisfy on-the-spot needs (10 meters get final product).
