Abstract
The utility model relates to a transformer substation telemechanical remote signaling back-up system, for performing accident alarm to the transformer substation including a central signal screen. The back-up system includes a signal export intermediate relay, connected to the central signal screen for receiving accident signals and outputting starting signals; an alarm connected to the signal export intermediate relay, for starting up according to the starting signal received from the signal export intermediate relay and outputting the alarm signals to outside. The utility model has advantages of practical feasibility, economy, installation ease, low investment cost, capability of replacing the communication channel to perform accident alarm to the transformer substation when the communication channel goes wrong, quick response, safety, reliability and so on.
Description
Technical field
The utility model relates to a kind of transformer station's telemechanical remote signalling back-up system that is used for the substation accident warning.
Background technology
Flourish along with urban economy, large enterprises settle in succession in each big industrial area, the continuous quickening of power network development speed, the electrical network new equipment amount of putting into operation sharply increases in the district.Transformer station is unattended to be a kind of advanced management measure of power supply enterprise, and the unattended substation trouble signal is in time sent, handled rapidly to scheduling, can control and dwindle the accident scope, is an essential condition that improves power supply reliability.
Above-mentioned trouble signal all transmits to the dispatching terminal main frame by communication port, therefore when communication port breaks down, will have a strong impact on transformer station's power supply safety.In the prior art, after the communication port fault is found in the control room, promptly send the operator on duty and rush towards field service usually, this need employ a large amount of technical staff, and the reaction time is long, thereby may cause the generation of major accident.
The utility model content
In order to overcome the deficiency that above-mentioned prior art exists, the utility model aims to provide a kind of simple and easy, economic, feasible transformer station's telemechanical remote signalling back-up system, can be when communication port breaks down, replace communication port that transformer station is carried out accident alarming, and advantages such as it is fast to have reaction, safe and reliable.
A kind of transformer station described in the utility model telemechanical remote signalling back-up system is used for transformer station is carried out accident alarming, and described transformer station comprises central signal screen, and it is characterized in that: it comprises:
The signal outlet auxiliary relay is connected with described central signal screen, is used to receive trouble signal, and the output enabling signal;
Alarm is connected with described signal outlet auxiliary relay, is used for starting according to the enabling signal that receives from described signal outlet auxiliary relay, and to extraneous output alarm signal.
In above-mentioned transformer station's telemechanical remote signalling back-up system, described alarm is by the telephone wire output signal.
In above-mentioned transformer station's telemechanical remote signalling back-up system, the signal outlet auxiliary relay has a pair of normal opened contact.
Owing to adopted above-mentioned technical solution, the utility model can replace communication port that transformer station is carried out accident alarming when communication port breaks down, and has fast, safe and reliable, simple and easy, the economic dispatch advantage of reaction.
Description of drawings
Fig. 1 is the block diagram of a kind of transformer station of the utility model telemechanical remote signalling back-up system.
Embodiment
As shown in Figure 1, the utility model, promptly a kind of transformer station telemechanical remote signalling back-up system is used for transformer station is carried out accident alarming, and described transformer station comprises central signal screen, and the utility model comprises signal outlet auxiliary relay 1, alarm 2.
The central signal screen 10 of signal outlet auxiliary relay 1 and transformer station is connected, is used to receive trouble signal, and the output enabling signal, and signal outlet auxiliary relay 1 has a pair of normal opened contact (not shown), can adopt the conventional products realization;
Alarm 2 is connected with a pair of normal opened contact of signal outlet auxiliary relay 1, be used for starting according to the enabling signal that receives from signal outlet auxiliary relay 1, and by telephone wire to extraneous output alarm signal.
Operation principle of the present utility model is as follows: when accident appears in transformer station, and communication port is can't operate as normal the time, and the central signal screen 10 of transformer station sends trouble signal, and a pair of normal opened contact closure of signal outlet auxiliary relay 1 is promptly exported enabling signal; This of alarm 2 and signal outlet auxiliary relay 1 is connected normal opened contact, start alarm 2 immediately, alarm 2 can be finished to the control room according to the phone number dial of prior setting, by the local telephone line automatically and send alarm signal then, to reach the warning purpose.
In the utility model, can choose alarm with following function:
1, needs and to realize dialing automatically by the local telephone line, send the recording of warning language.
2, self-contained battery is arranged, also can normally move even lose alternating current.
3, can select 3 above telephone numbers, circulation is dialed, and guarantees that the dispatcher receives signal.
4, action is in time reliable, and the reaction time can not be greater than 3 seconds.Trouble signal takes place to be not more than two minutes to the generation of control room alarm sound from transformer station.
5, low price.
6, trouble signal has priority, can normal talking when not having trouble signal.
The type of alarm that has above-mentioned functions on the market is a lot, for example pacifies special burglar alarm, and model is CR-586.
In sum, the utility model economically feasible, easy for installation, cost of investment is low, can be when communication port breaks down, replace communication port that transformer station is carried out accident alarming, and have advantages such as reaction is fast, safe and reliable.
Below embodiment has been described in detail the utility model in conjunction with the accompanying drawings, and those skilled in the art can make the many variations example to the utility model according to the above description.Thereby some details among the embodiment should not constitute qualification of the present utility model, and the scope that the utility model will define with appended claims is as protection range of the present utility model.
