Hydroelectric generator with light resistance

Abstract

The invention discloses a hydroelectric generator with light resistance. The hydroelectric generator with light resistance comprises a magnetic tent, an iron core coil and water vanes. The magnetic tent is composed of two parts of permanent magnetic blocks; all the N poles of one part of the permanent magnetic blocks point towards the inside of the magnetic tent, and all the S poles of the other part of the permanent magnetic blocks point towards the inside of the magnetic tent, so that a radial magnetic field is formed in the magnetic tent; the stator is composed of an iron core and a coil; the stator is arranged in the magnetic tent through a rotating shaft; the rotating shaft is located at the interval of the two parts of the permanent magnetic blocks; the magnetic tent serves as a rotor; the water vanes are arranged in the magnetic tent and are of a paddle structure for bearing the hydropower in the radial direction. The technical characteristics are that the iron core made of a silicon steel sheet is a rod-shaped iron core in a certain length, and the coil winds the middle section of the rod-shaped iron core. The coil winds the middle section of the rod-shaped iron core and covers 1 / 3 or 1 / 2 of the rod-shaped iron core. The hydroelectric generator with light resistance not only realizes efficient light resistance of the electric generator, but also reduces excessive loss of the firepower resource through full utilization of a fall head type hydraulic resource, and can improve the atmospheric environment, the ecological environment and the human living environment.

Description

technical field [0001] The invention relates to a generator, in particular to a hydraulic light resistance generator. Background technique [0002] As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. Its reserves are huge. The global wind energy is about 2.74×109MW, of which the usable wind energy is 2×107MW, which is 10 times larger than the total amount of water energy that can be developed and utilized on the earth. China's wind energy reserves are large and widely distributed. The wind energy reserves on land alone are about 253 million kilowatts.

Problems solved by technology

[0005] However, wind power also encounters many problems in the development: 1. Noise and visual pollution; 2. Occupying a large area of ​​land; 3. Unstable and uncontrollable; 4. The current cost is still high; migration)

However, at present, the thermal efficiency of the power plant (coal-fired, oil-fired) that drives the generator cannot break through 54% (this can be described as an "eternal" technical bottleneck)

Constrained by the cost of superconducting use and the bottleneck of "eternal" technology, the actual situation faced by the market is that the output efficiency of generators is basically still around 75%, and water and fire resources continue to be excessively depleted
