Description
Technical field
The present invention relates to a kind of generator, particularly gas turbine generator.
Background technology
At industrial circles such as oil, chemical industry, natural gases, they are need be mobile convenient to the requirement of mechanically operated power-equipment, explosive outdoor location operation can easily dyed, conventional electric generators is generally not removable, must cheat by backactor during installation, need be placed in the special-purpose factory building, and the waste gas that produces during oil, natural gas extraction, coal gas processing and iron and steel enterprise produced can not be used, caused the waste of the energy, and pernicious gas, solid flue dust such as sulfur dioxide and nitrogen oxide are emitted on contaminated environment in the atmosphere." the further exploitation of the enforcement of West-east Gas engineering and marine energy sources, the electric power energy that can satisfy its demand becomes urgent problem along with country.
Summary of the invention
Purpose of the present invention promptly is to overcome the shortcoming of prior art, the gas turbine generator that provides a kind of and easily move, remove and be convenient to install, and its sufficient combustion, no solid soot emissions, free from environmental pollution.
Purpose of the present invention is achieved through the following technical solutions: gas turbine generator is the packaged type unit, adopt the integral type body structure, generator is positioned in the main body cabinet, the generator main frame adopts double bracing integral arrangement structure, the floor is the integral type floor, generator vapour end bearing side is provided with windshield, and exciter directly is placed in generator and encourages on the end bearing;
Generator unit stator is a square box formula structure, and stator coil adopts basket type half coil, and slot part adopts 360 degree transpositions, be provided with the hot blast air outlet at the stator top, leading-out terminal is positioned at the stator both sides, is provided with flexible leading-out terminal, and outdoor rain proof type neutral ground cabinet is housed in the neutral point outlet;
Generator amature is provided with radial line embedding groove, and little tooth two ends have ventilation slot, and canine tooth also has ventilation slot, and lead-out wires of coil all is positioned at exciter side, and causes exciter rectifying disc place by centre bore;
Dynamo bearing adopts the sliding bearing of pressure forced oil-circulation, and the sphere bearing shell of energy automatic aligning is arranged;
The generator circulating ventilation system adopts radial double-flow sealing and circulating ventilating system, and the air cooler accumbency is installed in the air cooler case at generator top, is provided with the drainage arrangement and the detector that leaks in the air cooler case;
Exciter adopts intermediate frequency generator, and rectifying disc is put in the exciter end, and all lead-out wires of unit all cause on the outlet terminal box that is fixed on the floor.
The both sides, floor are provided with for the top board of regulator generator position of center line and position, the left and right sides and play top fastening bolt, and are provided with the axial restraint side plate.
Encourage the end end cap left and right sides and be provided with generator lead-out wire outlet box, bottom is provided with generator heating and dehumidification electric heater.
Vapour end bearing and encourage the end bearing bearings at both ends and cover double-deck oil baffle is housed is equipped with vibration measuring system and Displaying Meter on the bearing.
By top narration as can be seen, the present invention has the following advantages: gas turbine generator is the packaged type unit, install simple and direct, need not be placed in the special-purpose factory building, advanced technology, efficient height, small investment, pollution-free, gas turbine need not the configure host boiler, can effectively reduce input cost, the using waste heat from tail gas of gas turbine discharge simultaneously can also carry out secondary electricity generation (a common 15MW gas turbine can dispose the vapor wheel generator of a 3MW at least) by heating boiler, has improved the heat efficiency to greatest extent, thereby has saved Limited resources.
