Abstract
The utility model relates to an inertia AC generator which can generate electricity by using inertial energy. The utility model comprises a seal outer shell, an extraction valve, a connection box and a horizontal installation base which are connected with each other, wherein the lower end of the outer shell of the generator is connected with a permanent magnet bearing, a rotor, a winding and the horizontal installation base; the middle segment of the outer shell is connected with a stator and the winding; the winding is electrically connected with connection box, and the upper end of the outer shell is connected with the permanent magnet bearing, the rotor and the winding. By adopting the structure of the utility model, the air which is sealed in the outer shell can be drawn out, and the three-phase winding is supplied with the three-phase alternating current; so the rotor can rotate because of induced electromotive force. The rotor is not hindered by the bearing and the air after a power supply is cut off, so the inertia AC generator can generate electricity in an inertial rotation mode in a long time. When the speed is slower than the rated revolution speed, the power supply is switched on again to start the inertia AC generator.
Description
The utility model relates to a kind of Blast Furnace Top Gas Recovery Turbine Unit (TRT), especially can realize being accustomed to the use of the inertia alternating current generator of performance generating.
At present, known alternating current generator is to be formed by connecting by shell, terminal box, bearing, stator, rotor, winding, brush, slip ring, fan etc.Engine passes to generator with mechanical energy, and generator is converted into electric energy with mechanical energy.But generator becomes electric energy with the mechanical energy development of evil in febrile disease, is the process that mechanical energy is converted into electric energy, can not realize being accustomed to the use of the performance generating.
The purpose of this utility model provides a kind of inertia alternating current generator.
The purpose of this utility model is achieved in that can, extraction valve, terminal box, level is installed base and is connected, generator casing lower end and Permanent-magnet bearing in can, rotor and winding, level is installed base and is connected, the generator casing stage casing is connected with stator and triple line group, three-phase stator winding is electrically connected with terminal box, generator casing upper end and Permanent-magnet bearing, rotor and winding, level is installed base and is connected, the generator casing stage casing is connected with stator and triple line group, three-phase stator winding is electrically connected with terminal box, generator casing upper end and Permanent-magnet bearing, rotor and winding connect.The can inner air is taken out the inside from extraction valve be vacuum, feed three-phase alternating current to three-phase stator winding, stator winding produces rotating magnetic field, the rotor winding is rotated by induced electromotive force, when rotor speed reaches normal speed, cuts off the electricity supply, rotor is made long-time inertia because of the resistance that is not subjected to bearing and air and is rotated, magnetic pole produces magnetic field by the remanent magnetism self-excitation, and the three-phase stator winding cutting magnetic line produces alternating current, transfers to external power grid through terminal box.Owing to be subjected to the influence of terrestrial gravitation and magnetic resistance, the prolongation that rotor speed can be in time and stopping slowly when speed is lower than rated speed, then feeds three-phase alternating current again and starts.
Owing to adopt such scheme, use the inertia rotary electrification of rotor after can cutting off the electricity supply with generator.Only take out air bearing in the can and adopt Permanent-magnet bearing, structure and processing are simple.
Below in conjunction with drawings and Examples the utility model is further specified.
Figure is the utility model three-view diagram and sectional structural map, the A-A cutaway view.
Among the figure 1, Permanent-magnet bearing; 2, rotor and winding; 3, stator and winding; 4, generator casing; 5, terminal box; 6, can; 7, level is installed base; 8 extraction valves; 9, vacuum.
In the figure illustrated embodiment, can (6), extraction valve (8), terminal box (5), level are installed base (7) and are connected, and it is discerptible two parts with can (6) that level is installed base (7).Generator casing (4) lower end and Permanent-magnet bearing (1), rotor and winding (2) are connected, and join toward lower end and level installation base (7) again.Generator casing (4) stage casing is connected with stator and winding (3), and stator winding (3) is electrically connected with terminal box (5).Generator casing (4) upper end is connected with Permanent-magnet bearing (1) rotor and winding (2).Rotor and winding (2), designing requirement can not have friction, so except that with Permanent-magnet bearing internal ring portion spare contacts, do not contact with any other parts, rotor magnetic pole is cut off the electricity supply the back by remanent magnetism self-excitation generation N, S magnetic pole, because fan is not set, winding material is wanted can be high temperature resistant, and the mouse cage winding of surface distributed is closed high temperature resistant copper bar.Stator winding (3) is the identical winding of three-phase structure, and this three phase winding respectively differs 120 ° of electrical degrees on the locus, and wiring is by star connection.
