Description
Technical field
The utility model relates to a kind of electricity generator stator coil end three water circuit system cooling structures, be used to make electricity generator stator coil end (comprising stator coil, ring in parallel, main lead-in wire and outlet sleeve pipe) to form three kinds of separate cooling water channels, belong to the turbo generator technical field.
Background technology
Usually in large turbo-type generator, the type of cooling of main circuit parts in its machine (comprise stator coil, be positioned at the parallel connection ring of encouraging the end end, main lead-in wire and outlet sleeve pipe etc.) mainly adopts hydrogen-cooled or water-cooled.For adopting hydrogen-cooled generator end loop construction,, need distinguishingly design its high/low pressure wind district and pairing turnover wind mode and position according to the situation of hydrogen wind path in the machine; Generator pit and outlet box junction need the design isolated hermetically-sealed construction, so just make the structure more complicated of whole generating machine end, sealing and security requirement to assembling are higher, and because the restriction of the inner hydrogen pressure of generator, the cooling effect of hydrogen is not as water cooling.
For the generator end loop construction that adopts water-cooled, water cooling that the structure of common design can go between the parallel connection ring with the master and the outlet sleeve pipe be connected, even stator coil also can be cascaded.Because the structure difference of each parts, the water resistance of its water passage, flow, flow velocity and hydraulic pressure degradation parameter are all inequality, are cascaded to carry out water cooling and may cause water yield maldistribution in each cooling water channel, thereby influence cooling effect.Because a plurality of unit Series coolings, the part temperatures that is positioned at whole water route after-stage is higher, and its leaving water temperature also can't react the concrete temperature rise and the ruuning situation of its each parts of flowing through, when occurring local temperature in the machine when too high, and can't be in time, react sensitively and regulate.
Summary of the invention
The purpose of this utility model provides a kind of higher cooling structure of reliability that can effectively promote electricity generator stator coil end cooling effect.
In order to achieve the above object, the technical solution of the utility model provides a kind of electricity generator stator coil end three water circuit system cooling structures, it is characterized in that, comprise stator cooling water water inlet manifold, stator cooling water water inlet manifold connects encourages the end water inlet manifold, encourages the end water inlet manifold and connects stator coil cooling water water inlet insulated tube, ring cooling water water inlet insulated tube in parallel and main lead-in wire and outlet jacket cooling water water inlet insulated tube respectively;
Wherein, stator coil cooling water water inlet insulated tube, stator coil, stator coil cooling water water outlet insulated tube and the total outlet pipe of vapour end connect successively;
Ring cooling water water inlet insulated tube in parallel, ring in parallel, ring cooling water water outlet insulated tube in parallel and encourage end ring in parallel outlet pipe and connect successively;
Main lead-in wire is connected successively with outlet jacket cooling water water inlet insulated tube, main lead-in wire, lead collar and outlet jacket cooling water collection pipe.
The utility model has three effects greatly for the lifting of electricity generator stator coil end cooling effect and reliability:
1, encourages the end water inlet manifold in the utility model and connect stator coil, ring in parallel and main lead-in wire and outlet sleeve pipe respectively, cooling water is divided into independently three cooling water channels by the insulation aqueduct.Each road cooling water all is used to cool off corresponding components from encouraging the direct water intaking of end water inlet manifold (being cold water area), can effectively reduce its temperature rise and hot(test)-spot temperature;
2, the separate water outlet of each road cooling water has effectively been avoided because different water resistances of each cooling water channel and hydraulic pressure fall and the situation of issuable water yield maldistribution;
3, each road cooling water monitoring and adjusting separately outside machine makes the temperature rise and the cooling situation of critical pieces such as electricity generator stator coil, ring in parallel, main lead-in wire and sleeve pipe react more responsive, regulates more convenient.
