Abstract
The utility model discloses a wireless shear pin signal detecting device of a hydroelectric generating set. The wireless shear pin signal detecting device comprises a shear pin annunciator and a PLC (Programmable Logic Controller), wherein the shear pin annunciator comprises a wireless sensor, and the PLC is provided with a wireless communication module and used for receiving a data signal of the wireless sensor through the wireless communication module. According to the wireless shear pin signal detecting device of the hydroelectric generating set, disclosed by the utility model, a switching value measuring technology based on the wireless communication principle is adopted in. Short-distance wireless signal transmission and acquisition are realized in a waterwheel chamber, so that a great deal of electric wire aligning and clearing work during the overhaul period is avoided, and meanwhile, the electric interference is reduced.
Description
Technical field
A kind of Hydropower Unit of the utility model is wireless break pin signal supervisory instrument is used for Hydropower Plant break pin secondary control system.
Background technology
When Hydropower Plant is hung rotor in overhaul, need a large amount of secondary measuring sensor and signal are removed, need back dress and signal to check after the maintenance, need a large amount of work.During unit operation, the break pin signalizing activity need be shut down processing simultaneously.
The break pin signalling means is installed in the axial center hole of break pin usually or is stuck on the connecting lever, and main effect is the break pin fracture accident of reflection hydraulic turbine guide vane connecting rod.Installing wireless signal device in each break pin, if guide vane is stuck, break pin is cut off sends alerting signal in operational process, upstream emergency gate emergency shutdown falls.Simultaneously, because the position is narrow, usually need through accurate adjustment installation site, need a large amount of works on the spot.
Summary of the invention
The utility model provides a kind of Hydropower Unit wireless break pin signal supervisory instrument, based on the switching value measuring technique of wireless telecommunications principle.A large amount of electric to line and the work of taking out stitches between turn(a)round reduced or remitted in short-range signal wireless transmission and collection in water wheel chamber, reduced electrical Interference simultaneously.
Above-mentioned purpose of the present utility model is to realize by such technical scheme: a kind of Hydropower Unit is wireless break pin signal supervisory instrument, comprise the break pin signalling means, the PLC controller, described break pin signalling means comprises wireless senser, described PLC controller is provided with wireless communication module, and the PLC controller is accepted the data-signal of described wireless senser by wireless communication module.
Described wireless senser is provided with normal opened contact, normally closed contact, is used for same signal is carried out redundant measurement.
Described wireless senser is provided with two Battery packs: main battery, reserve battery, described two Battery packs are used for redundant power supply.And can the active and standby battery of online replacing.
Described wireless senser is provided with the electric weight warning device, and described electric weight warning device comprises a plurality of LED lamps.
Described wireless senser is provided with the card rail, described card rail is made up of fastener for installing and base plate, described fastener for installing is used for fixing wireless senser, and described base plate is provided with vertical adjusting bolt and lateral adjustments bolt, regulates bolt and moves in the vertical and horizontal position for the adjustment fastener for installing.
Described PLC controller adopts 48 parallel channel DI points, is connected with 24 groups of wireless sensers.
Described wireless senser is provided with switching value and compresses the contact.
A kind of Hydropower Unit of the utility model is wireless break pin signal supervisory instrument adopts the principle of wireless transmission, short-range signal wireless transmission and collection in water wheel chamber, reduced or remitted between turn(a)round a large amount of electric to line with take out stitches work.Simultaneously at unit at run duration, if the misoperation of break pin signalling means is not electrically connected because this device has with control system, only signal shielding need be snapped in new sensor in abort situation, rebulid communication and get final product, significantly reduce the non-number of times that stops, increased security.
