Abstract
A 600MW grade nuclear power conventional island generator auxiliary engine stator cooling water system is disclosed. The system is formed by a stator cooling water box, a water pump, a water cooler, a water filter and an ion exchange. The cooling water passes through the stator cooling water box, the water pump, the water cooler and the water filter, enters into an annular main water inlet pipe in a generator engine base, brings heat of a generator stator coil to the outside world and then returns to the stator cooling water box so that one closed circulation is completed. When the generator operates normally, parts of water which flows from the cooler is processed by the ion exchanger so as to reduce a cooling water conductivity and then flows into the stator cooling water box. The system is designed, made, tested and used based on a nuclear power quality guarantee system requirement. A design margin of the water cooler is increased and all condition operation of the generator is satisfied. Filtering precision of the water filter is increased. Impurities in the stator cooling water are removed so that blocking of the stator coil is effectively prevented.
Description
Technical field: the utility model relates to 600MW level nuclear power conventional island generator subsidiary engine stator cooling water system field.
Background technology: subsidiary engine stator cooling water system is one of nuclear power conventional island generator unit important component part, and can the stability of its operation and reliability are directly connected to generator safe and stable operation.Conventional stator cooling water system product can not meet the requirement of nuclear power station conventional island Generator Stator Cooling water system, as: conventional water filter filtering precision does not meet 3 microns of requirements; Conventional water cooler design margin does not meet nuclear power product requirement; The conventional products part design life-span does not meet nuclear power product requirement; Conventional stator chilled water unit designed reliability, fail safe does not meet nuclear power product requirement.
Summary of the invention:
The purpose of this utility model is to provide a kind of assurance winding temperature within the scope of design load, meet the full operating mode operation of generator, remove impurity in stator cooling water simultaneously, more effectively prevent the obstruction of stator coil, simple in structure, be convenient to the 600MW level nuclear power conventional island generator subsidiary engine stator cooling water system of installing, safeguarding, overhaul.The technical solution of the utility model is: 600MW level nuclear power conventional island generator subsidiary engine stator cooling water system, this system is made up of stator cooling water tank, water pump, water cooler, water filter, ion-exchanger, stator cooling water tank, as the storage cistern that draws water of water pump, is gone out the air release in stator cooling water simultaneously.Demineralized water enters the annular water inlet manifold in electricity generator stator stand through water pump, water cooler and water filter, the heat of electricity generator stator coil is brought out and returns stator cooling water tank, complete a closed cycle, in generator normal course of operation, flow out a part of water through ion-exchanger processing from cooler, reduce after recirculated water conductivity, then flow into stator cooling water tank.
The major function of 600MW level nuclear power conventional island generator subsidiary engine stator cooling water system is: provide continuously cooling water to generator unit stator winding; take away the heat that stator coil produces; filter out the impurity in high purity water, control its conductivity, and it is monitored and is protected.This system meets the requirement of nuclear power station to reliability, fail safe, and it has made up the deficiency of traditional subsidiary engine stator cooling water system, and it is mainly reflected in following several respects:
1) this cooling system requires design, manufactures, tests and application, fail safe, the reliability of assurance system in running based on nuclear power quality assurance system; Increase the design capacity of water cooler, meet the full operating mode operation of generator, and guaranteed the stability of summer condition operation;
2) improve water-supply structure between stator cooling water tank and water pump, make the backwater of stator cooling water tank more reasonable, avoid causing cavitation (in, the stability of enhancing system operation; Improve water filter filtering precision, remove impurity in stator cooling water, more effectively prevent that stator coil from stopping up;
3) stator cooling water system device is simple in structure, is convenient to install, safeguards, overhauls.The utlity model has system maturation, security of operation, the feature such as reliable, meet the requirement of applying under this special occasions of nuclear power station completely.
Accompanying drawing explanation:
Fig. 1 is 600MW level nuclear power conventional island generator subsidiary engine stator cooling water system flow chart
Embodiment:
As shown in Figure 1, a kind of 600MW grade nuclear power station conventional island generator subsidiary engine sealing oil system, this system is made up of stator cooling water tank 1, water pump 2, water cooler 3, water filter 4, ion-exchanger 5, stator cooling water tank 1, as the storage cistern that draws water of water pump, is gone out the air release in stator cooling water simultaneously.Demineralized water enters the annular water inlet manifold in electricity generator stator stand through water pump 2, water cooler 3 and water filter 4, the heat of electricity generator stator coil is brought out and returns stator cooling water tank 1, complete a closed cycle, in generator normal course of operation, flowing out a part of water from water cooler 3 processes through ion-exchanger 5, reduce after recirculated water conductivity, then flow into stator cooling water tank 1.
Generator Stator Cooling water system is in the overall process of generator operation, provide the satisfactory water of temperature, flow, pressure and quality (water quality and purity) as coolant, heat winding loss being produced by stator winding air core coil is taken out of, in water cooler 3, takes away by closed-type circulating cooling water the heat that high-purity stator cooling water absorbs from stator winding.This stator cooling water control system adopts closed cycle mode, makes continuous high purity water stream by stator coil hollow conductor, takes away coil loss.The water that enters generator unit stator is the qualified chemical demineralizing water directly coming from chemical workshop.The chemical demineralizing water that fills into stator cooling water tank 1 enters stator cooling water tank 1 after by ion-exchanger 5.Start preceding pipeline, valve, collection fill all elements and repeatedly flushing pollution discharge of equipment, until sampling of water quality chemical examination can be filled chemical demineralizing water to electricity generator stator coil after qualified.Softened water in stator cooling water tank 1 is sent into water cooler 3, water filter 4 after boosting by water pump 2, and then enters electricity generator stator coil, and the heat of electricity generator stator coil is brought out and returns stator cooling water tank 1, completes a closed cycle.In order to improve the water quality that enters electricity generator stator coil, 3～5% the water that enters generator total Water is constantly processed through the ion-exchanger 5 in this device, then get back to stator cooling water tank 1.
