Description
Technical field
The utility model relates to a kind of exciter for explosion-proof power generator, especially a kind of generator alternating current exciter and
The two-in-one structure of permanent magnetic auxiliary exciter, is mainly used on the AC exciter of generator, especially applies in explosion-proof power generation
On the AC exciter of machine.
Background technique
Currently, the AC exciter and permanent magnetic auxiliary exciter of existing generator are to separately design, permanent magnet is mounted on
On rotor, AC exciter is rotary using armature, and permanent magnetic auxiliary exciter uses armature state type, two machine occupied spaces when use
Greatly, control system is complicated, and there are security risks, and use is inconvenient for operation, increase the production cost of user.
Summary of the invention
The purpose of the utility model is to overcome disadvantages mentioned above, provide a kind of exciter for explosion-proof power generator, it leads
The AC exciter and permanent magnetic auxiliary exciter for solving existing generator are to separately design, and permanent magnet is mounted on rotor
On, two machine occupied spaces are big when use, and control system is complicated, and there are security risks, and use is inconvenient for operation, increase user's
The problems such as production cost.The purpose of this utility model is achieved in that a kind of exciter for explosion-proof power generator includes fixed
Son and rotor are constituted, and stator is by stator core, pole coil, the first insulation board, the second insulation board, permanent magnet mounting groove, permanent magnetism
Body composition, rotor are made of rotor core, rotor coil.Stator core is housed, pole coil is wrapped in stator core on stator
On, and the first insulation board and the second insulation board are housed, it is opened in stator core there are two permanent magnet mounting groove, permanent magnet is mounted on forever
In magnet mounting groove, rotor core is housed on rotor, rotor coil is wrapped in rotor core.The product structure is simple, design
Rationally, it is the two-in-one structure of generator alternating current exciter and permanent magnetic auxiliary exciter, eliminates permanent magnetic auxiliary exciter, by three machines
Excitation structure is changed to two-in-one both generators excitation structure, and using armature rotary structure, it has taken into account the performance of AC exciter,
The performance of permanent magnet excitation machine has been taken into account again, and the remanent magnetism voltage of the adjustable structure generator, two machines are integrated, occupied space
It is small, reduce the usage quantity of component, control system simple operations are convenient, improve the stability of exciter system and explosion-proof
The security reliability of generator reduces the production cost of user.

The insulation of 1-2-stator core of stator the 4-the first insulation board 5-the second of 3-pole coil
Plate 6-rotor core, 7-rotor coil, 8-rotor, 9-permanent magnet, 10-permanent magnet of mounting groove.
Specific embodiment
The most preferred embodiment that according to the present invention will be described in detail below with reference to the accompanying drawings, a kind of exciter for explosion-proof power generator
It is constituted including stator 1 and rotor 8, stator 1 is by stator core 2, pole coil 3, the first insulation board 4, the second insulation board 5, permanent magnetism
Body mounting groove 9, permanent magnet 10 form, and rotor 8 is made of rotor core 6, rotor coil 7.Stator core 2, magnetic are housed on stator 1
Polar curve circle 3 is wrapped in stator core 2, and the first insulation board 4 and the second insulation board 5 are housed, and opens that there are two forever in stator core 2
Magnet mounting groove 9, permanent magnet 10 are mounted in permanent magnet mounting groove 9, and rotor core 6 is housed on rotor 8, and rotor coil 7 is wound
In rotor core 6, when work, stator 1 is fixed on host base, and rotor 8 is fixed on the rotor of host, coaxial to operate.
Working principle, there are two permanent magnets on exciter stator, form a pair of of magnetic pole, when generator amature rotation, encourage
The magnetic line of force that magnetomechanical rotor coil can cut permanent magnet generation generates three-phase alternating current, and three-phase alternating current passes through on generator amature
The rectification of rotary rectifier diode become direct current, as the separate excitation power supply of main rotor, main machine armature generates the magnetic of fixed polarity
, magnetic field is rotated with rotor, cuts electricity generator stator coil, generates three-phase alternating current, and three-phase alternating current passes through AVR adjusting again
Afterwards, DC voltage is provided, DC voltage is loaded on the magnetic pole of the stator coil of AC exciter, induces pole coil generation
The magnetic pole of fixed polarity, and polarity is consistent with the polarity that permanent magnet generates, the two is overlapped mutually, and enhances magnetic field strength, magnetic
Flux increases, and by electromagnetic induction principle, the three-phase alternating current amplitude induced on exciter rotor becomes larger, such Zhou Erfu
Begin, increase the electric current of the self-excitation power supply of generator constantly, to make the voltage of generator end induction constantly increase, when reaching
When rated value, AVR can be measured to this signal, and by internal control algorithm, increase the DC voltage stability of output no longer,
To make generator voltage stablize.
