Abstract
The utility model relates to a guide vane shear pin fault monitor for hydroelectric generating sets, composed of a protection circuit, a monitoring circuit, and a signal circuit. Each guide vane can form a complete the protection, the monitoring, and the signal circuit. The utility model has the advantages of safety, high automatization, convenient repair and maintenance, simplicity, direct viewing, etc. The utility model is suitable for large, middle, and small hydroelectric generating set guide vane shear pin monitors, and AC and DC power supply all can be used.
Description
The utility model relates to a kind of monitoring device, particularly a kind of fault monitoring device of hydraulic generator unit stator break pin.
The signalling means kind of existing hydraulic generator unit stator break pin is more, travel switch formula (contact), bar type (as JDX series), pneumatic type etc. are arranged, all exist when the break pin of certain sheet stator is cut off, can only send fault, trouble-signal, the defective that but can't demonstrate concrete abort situation causes the maintenance difficulty big, and time-consuming longer.
The purpose of this utility model is to overcome the shortcoming of prior art, and a kind of display that can intuitively show the break pin abort situation is provided, and alleviates maintenance difficulty, for operations staff, dimension inspection personnel handling failure provide reliable foundation.
The utility model is achieved in that water wheels unit stator break pin fault monitoring device, is made up of protection loop, monitoring circuit and signal circuit three parts.The protection loop comprises direct supply, fuse, break pin signalling means, miniature auxiliary reclay; Monitoring circuit comprises direct supply, fuse, miniature auxiliary reclay contact, green LED, yellow light-emitting diode, current-limiting resistance; Signal circuit comprises direct supply, miniature auxiliary reclay contact, signal relay, button, alarm bell etc.Every stator all forms a complete protection, supervision, signal circuit.Its connected mode is: break pin signalling means one end of every stator is connected the positive pole of direct supply by fuse, and the other end links to each other with the negative pole of direct supply by miniature auxiliary reclay and forms one and protect the loop; The every related miniature auxiliary reclay of stator is got its three docking point, two docking points, one end wherein is connected the positive pole of direct supply by fuse, the current-limiting resistance of the other end by separately links to each other with yellow light-emitting diode with green LED respectively and is connected the negative pole of direct supply, form monitoring circuit, monitor different running statuses; One end of another docking point links to each other with the positive pole of direct supply, and the other end then links to each other with signal relay, button and alarm bell, and is connected the negative pole of direct supply, forms signal circuit.Under the normal operating condition, the miniature auxiliary reclay action of every stator, the junction closure that it links to each other with green LED, green LED is luminous.When the break pin of certain sheet stator broke down, the miniature auxiliary reclay of this sheet stator returned, and its contact that links to each other with green LED disconnects, and green LED extinguishes; The junction closure that it links to each other with yellow light-emitting diode, yellow light-emitting diode is luminous, and the contact that links to each other with signal relay simultaneously is also closed, sends alerting signal, and connects the remote monitoring device.
That the utility model has compared to existing technology is safe and reliable, automaticity is high, Maintenance and Repair are convenient, characteristics such as simple, directly perceived.Be applicable to large, medium and small type hydraulic generator unit stator break pin monitoring use, the AC and DC power supply all can.
The utility model further describes below with reference to the embodiment in the accompanying drawing:
