Summary of the invention
The objective of the invention is to: at the problem that above-mentioned prior art exists, propose a kind of simple in structure, can effectively avoid failing to report the water leakage alarm device for generator of wrong report.
Consider that the generator consequence of leaking is serious,, cause very big threat to generator is safe and reliable, even influence the safe operation of whole electrical network, so the applicant is to the relevant issues research that conducts in-depth analysis in case occur leaking and untimely discovery.
The applicant recognizes: the iron core of water-cooled generator relies on the air cooling, under the effect of two ends of rotor fan, air enters air gap through stator winding end, ventilation slot by stator core is pooled to the hot blast district again, after the air cooler cooling, enter the negative pressuren zone of fan by the air channel, both sides, form the wind path circulation.When leaking appears in generator unit stator, rotor or air cooler, because there are about 10 degree temperature difference in the chilled water of air cooler and hot blast, in through the wind path cyclic process, steam is inevitable to be condensed into water on the air cooler outer wall of air compartment, therefore, carry out alert detecting by the collection condensate water herein and will break through the thinking that traditional water leakage alarm facilities such as high resistant leak locator, the differential warning device of humidity consider a problem, avoid fully failing to report and reporting by mistake.
In order to reach above goal of the invention, the technical scheme that the applicant proposes is: water leakage alarm device for generator comprises the drainpipe that draws spontaneous motor cooling air chamber; The water delivering orifice below of described drainpipe is provided with the collecting bowl that is supported on lever one end; The other end stable equilibrium hammer of described lever; Described collecting bowl has perk and lowering position, and links with switching device; Described switching device is connected in the warning circuit, and the perk of corresponding collecting bowl and lowering position are in the state of disconnection and closed alarm circuit exists respectively.
For the present invention further improves be, the below of described collecting bowl is provided with the water induction device, and the make break contact and the switching device that are controlled by described water induction device are connected in parallel in the warning circuit.
The present invention has broken through the monitoring thinking of traditional high resistant leak locator and the differential warning device of humidity, the ingenious link of will monitoring is arranged near the air compartment of air cooler, and designed simple and effective monitoring alarm, because it is highly sensitive that balance bob is regulated, can accomplish that number drips enters water tumbler balance stem is moved, and then the trigger switch device sends alerting signal.As a result, do not exist moisture content under the fan effect, may cause the phenomenon that atomizes on the one hand, can not be subjected to the influence of extraneous humidity on the other hand, therefore effectively avoided failing to report and reporting by mistake.Especially, when two kinds of monitoring meanss are combined,, still can send alerting signal as the part of backup, thereby guarantee the reliability of this device even one of them breaks down.
