Abstract
The utility model discloses a segmental closing device of a speed governor of a water turbine generator set, which acts only in case of water machine protection, avoids too high frequency of actions under the normal condition, hardly influences a pipeline, is safe and reliable, has long service life and simple structure, and is easy to mount. The segmental closing device includes a mechanical segmental closing device, a programmable logic controller, an input module and an output module, as well as an electromagnetic valve coil and a segmental closing electromagnetic valve both mounted at an oil pipe of the mechanical segmental closing device, wherein output activating signals of the programmable logic controller reach to a water guide mechanism through the output module, the electromagnetic valve coil, the segmental closing electromagnetic valve and the mechanical segmental closing device; and inflection point signals of water guide blades of the water guide mechanism enter the programmable logic controller through the mechanical segmental closing device and the input module.
Description
Technical field
The utility model belongs to hydroelectric technical field, relates to a kind of subsection and closed device of hydraulic generator unit speed regulator particularly.
Background technique
Protect calculation requirement for the accent that satisfies Large Hydroelectric Set, hydraulic generator unit speed regulator adopts subsection and closed device.Present most subsection and closed device is the subsection and closed device of machinery, and as long as guide vane is through flex point, and subsection and closed device just starts.For frequency modulation, peak regulation unit, the guide vane adjustment is frequent, and the action of subsection and closed device is also just frequent, increases time of movement, and the pipeline vibrations are increased, and has potential safety hazard, reduces working life simultaneously.And complex structure, difficult installation.
Summary of the invention
The technology of the utility model is dealt with problems and is: overcome the deficiency of existing technology, provide a kind of and have only the water organizational security to protect just to move, avoid that the normal condition action frequency is too high, the pipeline influence is little, safe and reliable, long service life, simple in structure, the subsection and closed device that is easy to hydraulic generator unit speed regulator is installed.
The technical solution of the utility model is: the subsection and closed device of this hydraulic generator unit speed regulator; Comprise mechanical subsection and closed device, programmable controller, load module, output module; Also be included in the electromagnetic valve coil and the sequence closing solenoid valve of the oil pipe place installation of mechanical subsection and closed device; The output actuating signal of programmable controller arrives water distributor through output module, electromagnetic valve coil, sequence closing solenoid valve, mechanical subsection and closed device, and the guide vane corner position signal of water distributor gets into programmable controller through mechanical subsection and closed device, load module.
Because this device is installed electromagnetic valve coil and sequence closing solenoid valve at the oil pipe place of mechanical subsection and closed device; The output actuating signal of programmable controller arrives water distributor through output module, electromagnetic valve coil, sequence closing solenoid valve, mechanical subsection and closed device; The guide vane corner position signal of water distributor gets into programmable controller through mechanical subsection and closed device, load module, thus have only the water organizational security to protect just to move, avoid that the normal condition action frequency is too high, the pipeline influence is little, safe and reliable, long service life, simple in structure, install easy.
Description of drawings
Fig. 1 shows the circuit theory diagrams according to the subsection and closed device of the hydraulic generator unit speed regulator of the utility model.
Embodiment
As shown in Figure 1; The subsection and closed device of this hydraulic generator unit speed regulator; Comprise mechanical subsection and closed device, programmable controller, load module, output module; Also be included in the electromagnetic valve coil and the sequence closing solenoid valve of the oil pipe place installation of mechanical subsection and closed device; The output actuating signal of programmable controller arrives water distributor through output module, electromagnetic valve coil, sequence closing solenoid valve, mechanical subsection and closed device, and the guide vane corner position signal of water distributor gets into programmable controller through mechanical subsection and closed device, load module.
Because this device is installed electromagnetic valve coil and sequence closing solenoid valve at the oil pipe place of mechanical subsection and closed device; The output actuating signal of programmable controller arrives water distributor through output module, electromagnetic valve coil, sequence closing solenoid valve, mechanical subsection and closed device; The guide vane corner position signal of water distributor gets into programmable controller through mechanical subsection and closed device, load module, thus have only the water organizational security to protect just to move, avoid that the normal condition action frequency is too high, the pipeline influence is little, safe and reliable, long service life, simple in structure, install easy.
The above; It only is the preferred embodiment of the utility model; Be not that the utility model is done any pro forma restriction; Every technical spirit according to the utility model all still belongs to the protection domain of the utility model technological scheme to any simple modification, equivalent variations and modification that above embodiment did.
