Embodiment
Hereinafter, controlling switch according to the preferred embodiment of the invention is explained in detail with reference to the accompanying drawings.In addition, only to understanding this hair
The part that bright technological maheup is necessary is illustrated, and the explanation to remainder will be omitted, in order to avoid make the main idea of the present invention
It is chaotic unclear, this should be noticed.Moreover, in the process, clear property and convenience for convenience of description, shown in figure
The thickness of lines or the size of inscape and thickness etc. may be illustrated by exaggeration.
Fig. 1 is the composition block diagram of the controlling switch 1000 provided according to one embodiment of the invention.
As shown in figure 1, the controlling switch 1000 of the present embodiment includes：Accident protection trip switch unit 100, manual emergency
Halt switch unit 200, controller 300 and signal transmitting switch 400.
The accident protection trip switch unit 100, is connected with generating equipment 600, and one with mutual logic or relation
Accident protection trip switch 110 more than individual.Here, can set more than one (can in accident protection trip switch unit 100
To set 1,2 or more can also be set) accident protection trip switch 110, due to accident protection trip switch 110
Between be connected with logic or relation, therefore when any one accident protection trip switch 110 is acted and when tripping, phase therewith
Controller 300 even can accurately and reliably judge that generating equipment 600 breaks down.
The manual emergency halt switch unit 200, is connected with generating equipment 600, and two with mutual logical AND relation
Manual emergency halt switch 210 more than individual., can be with when the emergency such as fire (that is, deadly condition) occurs for power plant
By disconnecting the manual emergency halt switch 210 of manual emergency halt switch unit 200 come artificially emergency shutdown generating equipment
600.Here, two or more can be set (2 can be set, 3 can also be set in manual emergency halt switch unit 200
Or more) manual emergency halt switch 210, even if so that imprudence touches some manual emergency and stopped because of maloperation
Machine switchs 210, and then is allowed in the case of there occurs connection, therewith other manual emergency halt switches 210 of logical AND relation
Also in normal condition, therefore it can avoid occurring unnecessary loss.
The signal transmitting switch 400, is connected between controller 300 and scheduling station system 500, in generating equipment
In the case that 600 is grid-connected, in an ON state, and in the case where generating equipment 600 is not grid-connected, it is off.
The controller 300, is connected with accident protection trip switch unit 100 and manual emergency halt switch unit 200.
In the case where generating equipment 600 is grid-connected (signal transmitting switch 400 is in an ON state), when the tripping operation of arbitrary accident protection is opened
110 are closed when tripping, the generating equipment 600 that controller 300 is judged as breaks down and generation accident generation signal, and by the thing
Therefore occur signal and sent via signal transmitting switch 400 to scheduling station system 500, and when all manual emergency halt switches
210 when being switched on, and controller 300 is judged as that power plant occurs deadly condition (e.g., fire etc.) and generates manual emergency and shut down letter
Number, and the manual emergency stopping signal is sent to scheduling station system 500 via signal transmitting switch 400.In generating equipment
600 it is not grid-connected in the case of (signal transmitting switch 400 is off), when arbitrary accident protection trip switch 110 is sent out
During raw tripping operation, signal occurs for the generation accident of controller 300, because now signal transmitting switch 400 is off-state, therefore accident
Generation signal will not be transferred to scheduling station system 500, and when all manual emergency halt switches 210 are switched on, control
Device 300 processed generates manual emergency stopping signal, because now signal transmitting switch 400 is off-state, therefore manual emergency stops
Machine signal will not be transferred to scheduling station system 500.Here, the controller 300 can be that industrial computer etc. can
The arbitrary computer equipment of the functions such as calculating, logic judgment, storage and control is realized, this is not specially limited.Controller
300, which can also store accident that is grid-connected and not generating and under net state, occurs signal and manual emergency stopping signal, so as to backstage
Analyzed and studied.
Here, signal transmitting switch 400 can be arranged on the accident being connected with the steam turbine transformer unit as generating equipment
The side of trip protection switch element 100, signal transmitting switch 400 can be switched or knob switch using handle type, so that
Operating personnel are facilitated to be observed and operated.
More than, the composition to the controlling switch 1000 of the embodiment of the present invention is elaborated.Then, this hair is illustrated
The course of work of the controlling switch 1000 of bright embodiment.
When the generating equipment (steam turbine and/or steam turbine transformer unit) 600 in power plant is in and net state and normal work
When, connect signal transmitting switch 400.If generating equipment 600 breaks down, the accident protection being connected with generating equipment 600 is jumped
At least one accident protection trip switch 110 of lock switch element 100 can trip, and now the generation accident of controller 300 is believed
Number, and the signal transmitting switch 400 that signal state through the turned on occurs for the accident is sent to scheduling station system 500.If going out
The emergencies such as fire occur for existing power plant, then artificially stop all manual emergencies of manual emergency halt switch unit 200
Machine switch 210 disconnects, the now generation of controller 300 manual emergency stopping signal, and by the manual emergency stopping signal via connecing
The signal transmitting switch 400 of logical state is sent to scheduling station system 500.
Passed when the generating equipment (steam turbine and/or steam turbine transformer unit) 600 in power plant is in not simultaneously net state
When dynamic test, electrical test etc. are operated, cut-off signal transmitting switch 400.In this case, even if at least one accident protection is jumped
The tripping operation of lock switch 110 or all manual emergency halt switches 210 are switched on, and then the generation accident of controller 300 is believed
Number or manual emergency stopping signal, because signal transmitting switch 400 is off, therefore controller 300 can not possibly be to
Scheduling station system 500 sends accident and occurs signal or manual emergency stopping signal.That is, it is not grid-connected in generating equipment 600
Under state, even if carrying out various test operations, controller 300 also will not send irrelevant signal to scheduling station system 500.
The above is only the preferred embodiments of the present invention, it is impossible to the practical range of the present invention is limited with this, i.e., all
It is the simple equivalent substitution and modification made according to the claims in the present invention and invention description content, all still falls within culvert of the present invention
The scope of lid.
