Description
Technical field
The present invention relates to a kind of anti-secondary closing control device, be mainly used in the big-and-middle-sized equipment of thyristor rectifier.
Background technology
Thyristor in use, due to sole mass, the superpotential that electrical network produces, and the excess current that load short circuits causes, Long-Time Service water quality is bad causes fouling in heating radiator, bad and the excessive cooling water flexible pipe that causes of hydraulic pressure of radiating condition bursts, the factors such as the superpotential produced after shutting down cause thyristor to be damaged, equipment autoprotection circuit makes equipment auto stop, if now artificially again close main switch, rectifier transformer is likely made to burn, cause large-area power failure, power cabinet damage face expands further or causes the major accident of personal injury of operating personnel.
Summary of the invention
For overcoming the defect of prior art, the object of the present invention is to provide the anti-secondary closing control device of a kind of proterctive equipment and operating personnel's personal safety.
For achieving the above object, the technological means that the present invention takes is: anti-secondary closing control device, be arranged in the energy storage circuit of main circuit main switch, comprise auxiliary reclay unit, light-coupled isolation unit, comparator unit, advanced detecting unit, switch output unit, performance element, fault alarm unit, power supply unit, performance element exports point three tunnels, and a road connects auxiliary reclay unit, another road connects fault alarm unit, the 3rd tunnel is connected in the energy storage circuit of main circuit main switch, wherein advanced detecting unit connects performance element by switch output unit, performance element sends detection instruction to auxiliary reclay unit, when middle relay unit testing result is fault, then send instruction by light-coupled isolation unit to comparator unit, comparator unit exports high level to the switch output unit be attached thereto, switch output unit feeds back to performance element, another road fault alarm unit that performance element connects to it sends alarm command, fault alarm unit is reported to the police, the energy storage circuit of the 3rd road main circuit main switch of performance element control simultaneously disconnects all the time, power supply unit connects auxiliary reclay unit, comparator unit, advanced detecting unit, switch output unit.
The invention has the beneficial effects as follows: the action that the automatic detection and control main circuit of this device energy closes a floodgate, after rectification thyristor damages, forbid the energy storage that main circuit closes a floodgate, prevent main switch to close a floodgate, protect the personal safety of equipment and operating personnel.
Accompanying drawing explanation
Below in conjunction with view and embodiment, the present invention is described in detail.
Fig. 1 is schematic block circuit diagram of the present invention.
In figure: 1, auxiliary reclay unit, 2, light-coupled isolation unit, 3, comparator unit, 4, advanced detecting unit, 5, switch output unit 6, performance element, 7, fault alarm unit, 8, power supply unit, 9, the energy storage circuit of main circuit main switch.
Embodiment
Anti-secondary closing control device as shown in Figure 1, be arranged in the energy storage circuit 9 of main circuit main switch, comprise auxiliary reclay unit 1, light-coupled isolation unit 2, comparator unit 3, advanced detecting unit 4, switch output unit 5, performance element 6, fault alarm unit 7, power supply unit 8, performance element 6 exports point three tunnels, and a road connects auxiliary reclay unit 1, another road connects fault alarm unit 7, the 3rd tunnel is connected in the energy storage circuit 9 of main circuit main switch, wherein advanced detecting unit 4 connects performance element 6 by switch output unit 5, performance element 6 sends detection instruction to auxiliary reclay unit 1, when middle relay unit 1 testing result is fault, then send instruction by light-coupled isolation unit 2 to comparator unit 3, comparator unit 3 exports high level to the switch output unit 5 be attached thereto, switch output unit 5 feeds back to performance element 6, another road fault alarm unit 7 that performance element 6 connects to it sends alarm command, fault alarm unit 7 is reported to the police, the energy storage circuit 9 that simultaneously performance element 6 controls the 3rd road main circuit main switch disconnects all the time, power supply unit 8 connects auxiliary reclay unit 1, comparator unit 3, advanced detecting unit 4, switch output unit 5.
During normal work, this device is arranged near rectification thyristor, facilitates wiring.The alarm of fault alarm unit 7 is installed and the convenient position observed, and what especially need emphasis is the problem of withstand voltage of auxiliary reclay unit 1, according to the height of commutator tube primary voltage, handles the problem of withstand voltage of auxiliary reclay unit 1 well.
Before conjunction main switch, advanced detecting unit 4 first sends a signal and exports through switch output unit 5, makes performance element 6 action, performance element 6 point of three tunnel:
One tunnel controls main circuit and closes a floodgate, and forbids main switch energy storage;
One tunnel controls the relay of auxiliary reclay unit 1, make it adhesive, detect thyristor with or without damage, if damage detected, make the conducting of light-coupled isolation unit 2 optocoupler, compare through comparator unit 3, export noble potential, make switch output unit 5 open-minded, performance element 6 action, thus making main circuit main switch can not energy storage, main switch does not close, with this proterctive equipment and operating personnel's personal safety;
If it is intact to detect thyristor, then advanced detecting unit 4 makes switch output unit 5 turn off instantaneously, and this device throws off main circuit, and main circuit can normally close a floodgate.
One tunnel controls fault alarm unit 7, sends warning when having fault to occur.
The above, be the specific embodiment of the present invention, be not limited thereto, and is anyly familiar with those skilled in the art in the technical scope that the present invention shows, can expect the mode changing or replace easily, all should be encompassed within protection scope of the present invention.
