Abstract
The invention relates to a spare power automatic switching device and discloses a double-T inner bridge power substation spare power automatic switching device corresponding operation mode self-adaption device. A forced switch device is added at the position of a switching input terminal of the spare power automatic switching device, so that maintenance test can be performed for the spare power automatic switching device without shutting down one-time equipment. If a switch position forcing device is added, during testing, each switch position can be forced to be connected and disconnected, and the spare power automatic switching device can automatically recognize various operation modes. According to requirements of spare power automatic switching device functions for one-time equipment operation modes and actual operation modes of the one-time equipment, the spare power automatic switching device can automatically recognize system operation modes based on the switch positions, spare power automatic switching functions can be automatically spared, the maintenance test can be performed for the spare power automatic switching device without shutting down the one-time equipment, the continuous power supply of system load can be guaranteed, the load loss caused by system fault of a power supply system is reduced, the maintenance is convenient, and the safe usage of the spare power automatic switching device is guaranteed.
Description
Technical field
The present invention relates to a kind of backup auto-activating device, i.e. the corresponding operational mode self-reacting device of bridge electric substation backup auto-activating device in the double T.
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.
Summary of the invention
The objective of the invention is to provide a kind of for above-mentioned deficiency and do not stop under the primary equipment ruuning situation, realize 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 invention 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.
Advantage of the present invention is: 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 embodiments of the present invention are described in further detail.
