Description

The reservoir strobe frequency-converting control device
Technical field
The present invention relates to the keying control of storehouse access door under the storage station, specifically the reservoir strobe frequency-converting control device.
Background technology
Hydroenergy storage station is in order to guarantee that can cut off lower storage reservoir when overhauling comes water, is provided with bulkhead gate one specially for every diversion tunnel.This gate opens and closes for hydrostatic under normal circumstances, and gate is plane steel gate, is responsible for bulkhead gate by the wire rope hoist of lower storehouse gate control house and opens and closes.Braked by the service brake of headstock gear under normal circumstances, and be fixed in the inspection platform of gate shaft with mechanical caging.When maintenance need be closed, can operate headstock gear in hoist chamber, operating personnel close door after mechanical caging is manually withdrawed from, and gate is fallen close the aperture.Gate from before fully open position to closing fully, opening and closing under normal circumstances a time is 30min.
The former control system of access door headstock gear adopts the unitized construction of height lifting capacity comprehensive controller, PLC control, rheostatic speed regulation device and phase-wound rotor buncher.
What height and Weight control adopted is that height lifting capacity integrated display detects control mode, function and operability have not caught up with operation and the functional requirement of modern comfort, cause in carrying out gate opening/closing running test process and operating difficulties occurs, failure rate is high, equipment debugging is complicated, the equipment operational factor is not directly perceived, and job insecurity has not met the technical requirement of power plant safety operational system.
The control system method of operation before the headstock gear is by the operation of button on the operation board cabinet panel with the control headstock gear, on the switch board panel reometer is housed, be used for the surveillance electric current, derricking gear adopts two YZR threephase asynchronouses to drive in the power loop, and electric drive system in service starts and speed governing by the method for CJ20 series contactor Switch Rotor crosstalk resistance.Electric protection loop and electric control loop carry out the control of delaying time of logical interlock and the time relay by button, relay fully, and by the operation of contactor action drives.Headstock gear is used is that the metallic resistance that rotor series resistance speed, mode of speed regulation rely on the different resistances of rotor portion string consumes portion of energy to reach the speed governing effect, the shortcoming that has poor stability, undercapacity in low regime, will have the third party to brake and pull the guarantee gate when high-speed overload descends does not glide, this mode of braking will consume the power that mass energy is done braking, fallen the energy aspect, and only having small part is lifting heavy.Aspect electric motor protecting, owing to adopted and third-partyly pull the impact of motor greatlyr, in frequent use procedure, can make the excess Temperature of motor, affect the insulation accelerated ageing process of motor of motor.Aspect mechanical equilibrium, because the impulsive force of braking makes the vibration aggravation, accelerated the mechanical fatigue process.The wound-rotor asynchronous motor rotor series resistance speed belongs to energy consumption type slip speed governing, and energy consumption is large, and mechanical property is soft, and speed adjustable range is little, and flatness is poor.Mechanical property is soft during low speed, causes stop position inaccurate, easily causes security incident.
Summary of the invention
For solving the technical matters of above-mentioned existence, the invention provides a kind of reservoir strobe frequency-converting control device, simple in structure, powerful, adopt the color touch screen to operate and set, show and warning that frequency converter is realized the motor smooth starting, and is safe.
For achieving the above object, the present invention solves the technical scheme that adopts and is:
A kind of reservoir strobe frequency-converting control device; comprise the display screen supervising device; Programmable Logic Controller PLC and RHVC; described display screen supervising device is connected with RHVC with Programmable Logic Controller PLC respectively; described display screen supervising device adopts Siemens K-PT177B type color touch screen; described RHVC adopts MM440-45KW type frequency converter; described display screen supervising device is used for demonstration and comprises gatage; gate speed; frequency converter frequency; the various quantity of states of inverter current and opening and closing time; also be used for arranging all kinds of parameters and protection limit value thereof, also be used for showing the warning that surpasses all kinds of parameter limit values.
Store the various kinds of equipment operational manual in the described display screen supervising device.
The present invention has improved original baroque reservoir strobe open-shut control system, has adopted Siemens K-TP 177B color touch screen, operate directly perceived, powerful, dependable performance, extensibility is strong, has guaranteed power station bulkhead gate security of system reliability service; Adopt the frequency converter of Siemens MM440-45KW type, can realize the smooth starting of motor, and less to motor and power surges; In addition, can reach by the setting that changes frequency converter frequency the purpose of the speed that changes the gate lifting or descend, very convenient quick.
Description of drawings
Fig. 1 is structural principle synoptic diagram of the present invention.
Embodiment
Be described in detail below in conjunction with the drawings and specific embodiments:
As shown in Figure 1, this reservoir strobe frequency-converting control device, comprise display screen supervising device 1, Programmable Logic Controller PLC2 and RHVC 3, described display screen supervising device 1 is connected with RHVC with Programmable Logic Controller PLC2 respectively and is connected, described display screen supervising device 1 adopts Siemens K-PT177B type color touch screen, and described RHVC 3 adopts MM440-45KW type frequency converter.
Described display screen supervising device 1 is used for showing the various quantity of states that comprise gatage, gate speed, frequency converter frequency, inverter current and opening and closing time; also be used for arranging all kinds of parameters and protection limit value thereof; as carry out the demarcation of gatage bound and loading bound; the alarming value of gatage, loading, speed and electric current is set, and also is used for showing the warning that surpasses all kinds of parameter limit values.These settings and and setting value cryptoguard is all arranged, can prevent that layman mistake from revising.
Store the various kinds of equipment operational manual in the described display screen supervising device 1, even operating personnel do not have instructions again, be unfamiliar with in the situation of operating process, also can carry out proper operation according to the operation instructions in the touch-screen.
Described RHVC 3 adopts MM440-45KW type frequency converter, can realize the smooth starting of motor, and less to motor and power surges.In addition, can reach by the setting that changes frequency converter frequency the purpose of the speed that changes the gate lifting or descend, very convenient quick.
