Background technology
In the prior art, along with the requirement of the national economic development to power system reliability, the status of automatic throw-in equipment of emergency power supply (hereinafter to be referred as prepared auto restart) in electric power system is increasingly important.In inherent each transformer station of current our electric power system backup auto-activating device has been installed all.Now the backup auto-activating device of domestic tool flexibility is the CSC246A type backup auto-activating device that the Beijing Sifang Jibao Automation Co., Ltd produces, and its practical function can carry out the function logic establishment according to the physical cabling at scene.But this device lack of wisdom, operational reliability are not very high, in the light situation of system power supply load, produce easily maloperation situation.Therefore, periodic inspection.All be to carry out in the situation that primary equipment is not stopped transport when the postrun check of backup auto-activating device is most, in the process of doing experiment, need short circuit and cut-off switch position contact, to reach prepared auto restart RM function, increased many workloads, be necessary to carry out technological improvement at this device basic.
The utility model content
The purpose of this utility model is to provide a kind of for above-mentioned deficiency not stop under the primary equipment ruuning situation, realizes the corresponding operational mode self-reacting device of the interior bridge electric substation of double T backup auto-activating device of charged check.
Technical solution of the present utility model is: the corresponding operational mode self-reacting device of bridge electric substation backup auto-activating device is to open into the terminal place at it to increase the force switch device in the double T, and the primary equipment of realizing not stopping transport can carry out checking experiment to backup auto-activating device.
If increase position of the switch forcing device, can force switching just can make backup auto-activating device automatically identify variety of way to each position of the switch at the trial.By the requirement of backup auto-activating device function to the primary equipment operational mode, according to the actual operating of primary equipment, backup auto-activating device can according to position of the switch automatic recognition system operational mode, drop into corresponding prepared auto restart function automatically.
The utility model has the advantages that: the primary equipment of 1, realizing not stopping transport can carry out checking experiment to backup auto-activating device, guarantee the continuous power supply of system loading, reduce electric power system since the load loss that causes of the system failure, check is convenient, has guaranteed the backup auto-activating device safe handling.2, backup auto-activating device is realized all intellectualities, alleviates operations staff's labour intensity, increases the device reliability of operation, strengthens the stability of system power supply, improves the use flexibility of backup auto-activating device.
Below in conjunction with accompanying drawing execution mode of the present utility model is described in further detail.
