JP2003116220A - 120 Hz POWER DELIVERY SYSTEM - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide a resource saving system which reduces copper wires for coil winding (178,000 ton used in a year in the fiscal year 2000) and electromagnetic steel plates (2,000,000 tons used in a year) each down to half the level every year, when energy saving and resource saving are called for now due to global warming and everything is requested to be used efficiently and in a resource-saving manner. SOLUTION: A home electronic apparatuses used exclusively at 120 Hz is arranged by each area (2), and in a factory, an industrial apparatus is made, and power is supplied from a power distributing facility of 120 Hz. This is a 120 Hz power system, and for the electrical apparatus used here, a copper material or an iron material among all the principal materials is half the conventional one, and this is an economical 120 Hz power delivery area system which is constituted of a small and light-weight resource saving apparatus.

Description

Description: BACKGROUND OF THE INVENTION [0001] 1. Field of the Invention [0002] The present invention relates to a power distribution and power supply system including a power receiving end device. 2. Description of the Related Art Conventionally, the frequency of power supplied from a power plant on the earth is a two-frequency system of 50 Hz in Europe, 60 Hz in the United States, and 50/60 Hz in Japan and three other countries. 200V, 220V, 230
V, 240V 200V system and 100V, 115V 10
There is a 0V system, which is determined by the environment of the country. [0003] Recently, power is supplied and distributed at 50 Hz and 60 Hz by cogeneration under local conditions by private power generation. At present, energy saving and resource saving are being called for due to global warming, and it is required to operate all things efficiently and resource saving. In Japan, the demand for copper wire for coil winding in fiscal 2000 was 178,000 tons per year. Electrical steel sheet is 2,0 per year
Use of 00,000 ton (according to a survey by the Japan Electric Wire & Cable Makers Association, Japan Iron Works Federation). It was necessary to invent a resource saving system to reduce this by half every year. SUMMARY OF THE INVENTION The present invention increases the frequency of a power distribution system from current 60 Hz / 50 Hz to 120.
Hz solves the above problem. That is, in the case where the usage amount of the copper material (winding) and the iron material (iron core) used in the power distribution system is operated at 120 Hz from all the terminal devices, e = 4.44fnφ10 ⁻⁸ (V) is calculated according to Fleming's law. It is well known that e is the voltage, f is the frequency, n is the number of turns of the transformer and motor copper wire, and φ is the magnetic flux, which indicates the magnetic flux density Bm and the cross-sectional area S of the iron core, that is, the amount of the iron core. Therefore, the frequency f is set to 50 Hz / 60 Hz.
If it is changed to 120Hz, the amount of copper in transformers, motors, and electromagnetic devices can be reduced by half, that is, copper wire can be reduced by half. [0007] By doubling the frequency f of the iron amount, the magnetic flux φ can be halved. That is, if the magnetic flux density of the iron core is the same, the cross section is half, that is, the iron core can be halved. The amount of iron core or the number of windings generated in the system can be reduced by half. As another effect, in the market, the frequency is set to 1
By unifying to 20Hz, 50Hz / 60Hz products do not need to have a stock at the stage of production and distribution, the size is reduced by half, transportation cost and inventory storage fee are cheap. Further, since 120 Hz is an integral multiple of the hexadecimal number of a clock, the power supply frequency is used as a clock pulse in each individual device, so that home appliances, industrial devices, and other devices have control relations with good timing. One of the attractions is that it can be controlled. DETAILED DESCRIPTION OF THE INVENTION The present invention is applied to a power generation area unit of 120 units.
A more efficient power supply and distribution system will be realized by expanding from one area to the whole island and the entire continent by creating a Hz power supply and distribution system and expanding the cooperative connection with each area via a cooperative inverter. This is a useful invention that can be expected. [0011] In addition, since the time difference due to the difference in the latitude of the earth can be matched in the individual power generation unit of the cooperative inverter, it is expected that the future of the world will be developed with the aim of increasing the efficiency of distributed power generation and the same frequency.
