Abstract

The invention discloses a dual-frequency switching generator. The dual-frequency switching generator comprises a three-phase alternator circuit and a single-phase alternator circuit, wherein the three-phase alternator circuit is internally provided with an AVR chip U1, an AVR chip U2, an intermediate relay K1, a three-phase exciter M1, a rotary rectifier D1 and a main three-phase motor M2, the foot 7 and the foot 8 of the AVR chip U1and the AVR chip U2 are connected to the intermediate relay K1, the foot 7 of the intermediate relay K1 is connected to the U-phase electric input terminal of themain three-phase motor M2, and the foot 8 of the intermediate relay K1 is connected with the V-phase electric input terminal of the main three-phase motor M2. The dual-frequency switching generator can be regulated to different voltages and frequencies through the two AVR chips, when the external power utilization load information is transmitted to the intermediate relay K through conversion, theintermediate relay controls the AVR chip required being closed to achieve the seamless switching of the generator between different voltages and frequencies.

Description

technical field [0001] The invention relates to the technical field of brushless AC synchronous generators, in particular to a dual-frequency switching generator. Background technique [0002] Existing generators do not have the function of dual-frequency switching. In some occasions where the electrical load changes frequently, personnel are required to adjust and confirm the voltage and frequency in the voltage regulator of the generator, which has cumbersome operation and high operation and maintenance costs. High deficiency. Contents of the invention [0003] The purpose of the present invention is to provide a dual-frequency switching generator, which can be adjusted to different voltages and frequencies through two AVR chips. When the external power load information is transferred to the intermediate relay K through conversion, the intermediate relay control needs The closed AVR chip further realizes the seamless switching of the generator between different voltages...
