Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a temperature control system for hydroelectric generators used in hydroelectric power generation, to solve the problem that temperature measuring resistors are usually buried in the iron core of the stator in the prior art, and through these temperature measuring resistors Connected with monitoring equipment, the stator temperature can be monitored in real time, but since the rotor of the hydroelectric generator is a rotating part, if temperature measuring resistors are embedded everywhere in the rotor, it is necessary to install many brushes to lead out the signal, which will inevitably affect the power generation. The safe operation of the machine brings hidden dangers, and it is difficult to realize the problem in the process

Abstract

The invention discloses a hydro-generator temperature control system used for hydroelectric power generation. The structure of the system comprises an adjusting rotation shaft, an acousto-optic alarm,a temperature controller, an LED display, a bellows casing, an amplitude difference spring sleeve and a keyboard. According to the invention, an indirect method is used to measure the temperature ofthe rotor of a generator; a shunt, a current transducer and a voltage transducer are arranged to measure the temperature of the rotor of the generator; the measured current and voltage values pass through the temperature controller, and the measured temperature is transmitted to a processor for analysis and calculation; the temperature of the generator is controlled; embedding temperature measuring resistors in the whole rotor is avoided; the hidden danger of the safe operation of the generator is effectively avoided; the system has the advantages of simple operation and high practicability; the temperature controller can carry out remote communication to realize real-time monitoring of the temperature control of the generator; and the service life of the generator is effectively improved.

Description

technical field [0001] The invention relates to a water conservancy generator temperature control system for hydropower generation, which belongs to the field of hydraulic generator temperature control equipment. Background technique [0002] Water energy is an inexhaustible, renewable and clean energy. However, in order to effectively utilize natural water energy, it is necessary to artificially build hydraulic structures that can concentrate water flow and adjust flow, such as dams, diversion Water pipes and culverts, etc., so the project investment is large and the construction period is long, but the hydropower generation efficiency is high, the power generation cost is low, the unit starts quickly, and the adjustment is easy. Hydropower generation uses rivers, lakes, etc. The contained potential energy is converted into the kinetic energy of the water turbine, and then the water turbine is used as the driving force to drive the generator to generate electric energy, and...
