Description

Leakage water discharging structure of generator air cooler

Technical Field

The utility model relates to a leakage water discharge structure of a generator air cooler, and belongs to the technical field of generator auxiliary equipment.

Background

The prevention and timely discovery of cooler leakage during the operation of a hydropower station is often a problem that operation and maintenance managers need to pay attention. Because cooler seepage often has characteristics such as the disguise is strong, the harm is big, for example, thrust cooler appears the sand hole because of wearing and tearing, often need wait until oil level, tile temperature have obvious change and oil mix water alarm etc. alarm time can accurately judge, the water content of oil has exceeded standard at this moment, the cooling lubrication effect obviously reduces; the air cooler seepage is especially so, needs the operation personnel to get into the interior periodic inspection of patrolling of high-intensity magnetic field wind-tunnel and can effectively discover, has caused certain influence to the stator insulation before this, if the discovery is untimely, causes even that unit stator insulation descends and take place the ground connection and shut down, therefore the problem of generator air cooler seepage is not neglected.

Disclosure of Invention

In order to solve the technical problem, the utility model provides a leakage water discharge structure of a generator air cooler.

The utility model adopts the following technical scheme:

a diversion trench and a water leakage hole are formed in a bearing tube plate at the lower end of the air cooler, the bottom of the diversion trench is communicated with the water leakage hole, the water leakage hole is connected with an external pipeline, and a water baffle is arranged on the side, close to a stator, of the bearing tube plate at the lower end of the air cooler.

Preferably, a plurality of water leakage holes are uniformly arranged on the surface of the lower end pipe bearing plate of the air cooler, each water leakage hole is communicated to the diversion trench, and each water leakage hole is connected with the external pipeline.

Preferably, the external pipeline is a PVC pipe, and the PVC pipe extends into a drainage pit in the machine pit.

Preferably, the water baffle is fixed on the inner side of the lower end pipe supporting plate of the air cooler.

Preferably, the water baffle is made of stainless steel materials.

Has the advantages that: when the generator air cooler leaks, the leaked water flow is discharged to a drainage pit in the generator pit through the diversion trench and the external pipeline; the water baffle is arranged on the side, close to the stator, of the air cooler pipe bearing plate, so that water leakage is prevented from splashing to the stator bar, and insulation is prevented from being affected. The utility model can reasonably process the leakage water of the air cooler in time, and avoid causing bad results such as shutdown of the generator and the like to influence the power generation work of the hydropower station.
