What are the watt-hour meter and reactive watt-hour meter

 115/120 V AC Voltage and Three-phase Phase small 240v electric motor
Specifications
1.Specifications1.3-phase asynchronous motors 
2.IEC standard 
3.OEM 
4.Voltage:50HZ &60HZ;380V&415V 
5.Protection class: IP54 
 Electric energy can be converted into energy. Such as: through electric furnace is converted into heat energy, through the motor is converted into mechanical energy, by the light is converted into light energy, etc. In the conversion of electrical energy consumed ac electric motor in active power. And record the electric energy meter as watt-hour meter. Electrician principle tells us that there are some electrical apparatus in energy conversion at first have to establish a change of environment, such as: motor, transformer, etc to set up a magnetic field to make energy conversion, and some electrical equipment is to build an electric field to make energy conversion. To establish the electricity required to magnetic and electric fields are reactive power. And record the electric energy meter as reactive watt-hour meter. Reactive power in electric device itself is not consume energy, but can produce reactive current in the electric circuit, the current will generate a certain amount of loss in line. Reactive watt-hour meter is specially recorded a loss, generally only a large electrical unit to install the electric motor price active power meter table - use pointer indicating current device instantaneous value of active power consumption.

Measuring P watt-hour meter - they wore disk indicating the current consumption of the cumulative value of the active power. The W (W = PT) Active power meter is measured active power, it is different from the one ac voltmeter and ammeter and communicate list was made on the load in the value of total power, it must be less than or equal to the value of total power, this ratio is called power factor, with V table and A table of minus the total power with active power table measured active power reactive power value is the current line. Such as you put A few uF capacitor in series in the 220 V circuit (pressure more than 300 V) with active power table measured Single phase motor value should be the basic power is zero, and V table and A table for measured total power is not zero, because the currents and voltages, but because of its phase deviation of capacitor not electricity, so active power is zero, the rest are all reactive power, so you home electric meter (watt-hour meter) should not turn. (if turning slowly because the line resistance loss power) with active power than the total power on power factor.

SPC time-division switch

 generator Stator Rotor 
Specifications
1. 20 years manufacturing experience
2. competitive price,high quality
3. Accessories Series: stator and rotor
Program-controlled switches in general in the road section is analog voice signal transmission and exchange, thus habit called SPC digital exchange, as digital communications and pulse code modulation (PCM) technology rapid development and extensive application of the advanced countries in the world since magnet generator the '60 s with great enthusiasm to develop digital SPC exchange, after a long struggle, France in 1970, first in nyon (Lanion) launched the world's first successful SPC digital exchange system E10, it marks the switching from traditional analog switching into the era of digital switching. Due to the advanced nature of SPC digital exchange technology and equipment of economy, make up a new step, telephone exchange and to open the permanent magnet motors for sale business, implement integrated services digital switching laid a solid foundation, thus become the main development direction of switching technology, with the microprocessor technology and the rapid development of application-specific integrated circuit, the superiority of SPC digital exchange more and more obvious.

 At present the production of large capacity of PBX are all digital. Appeared after 90 s, our country gradually developed by a group of large and medium-sized capacity of digital program-controlled subscribers with the international advanced level, the typical such as for C&C 08 series of huawei company in shenzhen, xi 'an datang SP30 series, shenzhen zte ZXJ series and so on, the emergence of these switches, show that in the field of narrow-band switches, research and development of our country's technology has reached the world level. With the development of The Times, the ATM switch system gradually fusion, wireless communication, access network technology, HDSL, ASDL, video conference and other advanced technology. Single phase motor As you can imagine, switch system in the future, will not only voice transmission system, but a voice, text, images of high bit broadband transmission system, and deeply into people's homes. IP phone is its application example. Traditional switch manufacturers in the world are trying to develop, and through the cooperation and communication with computer manufacturers, in order to achieve this purpose.
