Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the structural representation of wherein a kind of execution mode of the present utility model;
Fig. 2 is the structural representation of another kind of execution mode of the present utility model.
Embodiment
With reference to accompanying drawing, the design feature of this transformer station's master control device remote reboot control circuit comprises phone A, phone B, decompression voltage relay KV, A.C. contactor KM, very first time relay 1KT and the second time relay 2KT.Phone A and phone B is direct connection telephone, and phone A and phone B is arranged on remote scheduling room and substation field respectively.The coil T of decompression voltage relay KV is connected to the ring loop of phone B, the normally opened contact KV1 of decompression voltage relay connects with A.C. contactor KM and forms contactor branch road L1, very first time relay 1KT and the second time relay 2KT formation time relay in parallel branch road L2, contactor branch road L1 is in parallel with time relay branch road L2.The time of delay being greater than the very first time relay 1KT time of delay of the second time relay 2KT.One of them normally-closed contact 1KT1 of very first time relay 1KT is connected on contactor branch road L1, another normally-closed contact of very first time relay 1KT 1KT2 is connected on the ring-back circuit of phone B, and the normally opened contact 1KT3 of very first time relay 1KT is connected on time relay branch road L2.The normally-closed contact 2KT1 of the second time relay 2KT connects with the branch road of two after parallel connection.One of them normally opened contact KM1 of A.C. contactor KM is in parallel with the normally opened contact KV1 of decompression voltage relay KV, another normally opened contact KM2 of A.C. contactor KM is in parallel with the normally opened contact 1KT3 of above-mentioned very first time relay 1KT, and the normally-closed contact KM3 of A.C. contactor KM is connected on the electric power loop of master control device.
With reference to Fig. 2, the normally opened contact 1KT3 of very first time relay 1KT one of them normally-closed contact 1KT1 and very first time relay 1KT forms single-pole double-throw switch (SPDT), and this single-pole double-throw switch (SPDT) is connected between contactor branch road L1 and time relay branch road L2.Utilize the structure of this kind of single-pole double-throw switch (SPDT), can circuit connection structure be simplified, ensure the fast reliability of contact action.
In the utility model, utilize two direct connection telephone machines, a wherein total activation room a long way off, another portion is on-the-spot in transformer station's master control device room, when total activation room picks up the telephone A, the phone B of transformer station's master control device room and ring, the phone A of total activation room is hung up (put down the telephone from picking up the telephone to and can not exceed the time of delay of very first time relay), ring loop obtains electric, the coil T of decompression voltage relay KV obtains electric, the normally opened contact KV1 action of decompression voltage relay KV closes, A.C. contactor KM obtains electric, start A.C. contactor KM, the normally opened contact KM1 of the A.C. contactor KM in parallel with the normally opened contact KV1 of decompression voltage relay KV closes, keep in touch device branch road L1, another normally opened contact KM2 of A.C. contactor KM is closed starts very first time relay 1KT and the second time relay 2KT, the normally-closed contact KM3 of A.C. contactor KM disconnects, close master control device.After terminating time of delay of very first time relay 1KT, each contact action of very first time relay 1KT, disconnect contactor branch road L1 and retention time relay branch road L2, the normally-closed contact KM3 of A.C. contactor KM restPoses, and master control device obtains electric-opening, simultaneously, be connected to the normally-closed contact 1KT2 action of the very first time relay 1KT on phone B ring-back loop, start ring-back, the personnel in master control control room, the phone A jingle bell of total activation room, learns that master control device is restarted successfully.After terminating time of delay of the second time relay 2KT, the normally-closed contact 2KT1 of the second time relay 2KT opens, and disconnect contactor branch road L1 and time relay branch road L2, circuit restPoses, and ring-back terminates.Can not only realize Long-distance Control by this control circuit, whether power transmission is successful also to judge substation field by ring-back, uses more flexible.
For direct connection telephone, be generally used for the units such as electric power, railway, colliery.Before use, data set, and after off-hook, the user that direct calling data are pointed to, essence just refers to that key post phone must have the telephone relation taking up and just can lead directly to control room.The function that direct connection telephone has is the phone ring that the microphone of mentioning phone can make the other side.The below of microphone arranges snap switch, and when plucking microphone, snap switch action, in the utility model, namely the normally-closed contact 1KT2 of very first time relay 1KT instead of the function of this snap switch, thus the action of microphone is plucked in simulation, realizes automatic ringback.
In sum, the utility model is not limited to above-mentioned embodiment.Those skilled in the art, under the prerequisite not departing from spirit and scope of the present utility model, can do some changes and modification.Protection range of the present utility model should be as the criterion with claim of the present utility model.
