Embodiment Construction

[0014] Combine below figure 1 The present invention is described in detail, and the exemplary embodiments and descriptions of the present invention are used to explain the present invention, but not to limit the present invention.

[0015] The generator rotor wireless temperature measuring device includes a sensor 1 installed on the generator rotor coil. The sensor rotates with the rotor, and the sensor transmits the resistance signal of the rotor coil to the temperature acquisition module 2 installed on the generator rotor. The temperature acquisition module It can also rotate with the rotor, which is easy to install; the temperature acquisition module converts the resistance signal into a temperature signal and then transmits it to the temperature meter 3 installed on the generator frame through wireless transmission. The temperature meter is fixed; Monitor the temperature inside the rotor; as a preferred wireless transmission method, bluetooth, wifi, etc. can be used. Durin...

Abstract

The invention relates to a generator rotor temperature measurement technology, and particularly relates to a generator rotor temperature wireless measurement device. The device comprises sensors installed on a generator rotor coil. The sensors transmit resistance signals of the coil to a temperature acquisition module arranged on a generator coil. The temperature acquisition module converts the resistance signals into temperature signals, and transmits the temperature signals to a temperature instrument arranged on a generator frame by means of wireless transmission. By using the sensors, the temperature acquisition module and the temperature instrument and through the wireless communication technology, the technical problem on monitoring and alarm of the internal temperature of a rotor of a generator during work is solved, the internal temperature of a rotor can be monitored, the accident of rotor coil burnout caused by rise of the internal temperature of the rotor can be prevented, and the production safety of hydropower stations is strengthened.

Description

technical field [0001] The invention relates to a temperature measuring technology for a generator rotor, in particular to a wireless temperature measuring device for a generator rotor. Background technique [0002] A generator is a mechanical device that converts other forms of energy into electrical energy. It is driven by a water turbine, steam turbine, diesel engine or other power machinery, and converts the energy generated by water flow, air flow, fuel combustion or nuclear fission into mechanical energy and transmits it to the generator. Converted to electrical energy by a generator. Generators are widely used in industrial and agricultural production, national defense, science and technology and daily life. There are many forms of generators, but their working principles are all based on the law of electromagnetic induction and the law of electromagnetic force. Therefore, the general principle of its construction is: use appropriate magnetic and conductive material...
