I. Overview

A wholly-owned foreign-invested company in the Beijing Economic and Technological Development Zone is currently using an electric light source: a 400W metal halide lamp of a well-known brand, matching a deep-light type lampshade. The light source has large power consumption and low illumination. In September 2007, the Qingdao Franco 6U-60W high-frequency contract energy management special energy-saving lamp was used to directly replace the 400W metal halide lamp of a well-known brand to carry out lighting energy-saving technical transformation. The lighting effects and power saving benefits are analyzed as follows.

Second, the actual measurement site and personnel

(I) Actual measurement site: On September 20 , 2007, the production workshop of a wholly foreign-owned enterprise in Beijing Economic and Technological Development Zone was 9 meters high.

(II) Measured personnel: a wholly foreign-owned enterprise in Beijing Economic and Technological Development Zone,

Factory lighting manager, Mr. Liu

Qingdao Frank Microelectronics Co., Ltd., Beijing Business Center Mr. Liu

Third, the actual power analysis and comparison

(A), test instrument: single-phase active energy meter

(II) Test technical method: In the office of the production workshop, under the actual voltage state, 400W metal halide lamp and Qingdao Franco 6U-60W high frequency energy-saving lamp are respectively installed with one single-phase active energy meter. After 24 hours of actual measurement, the actual power is calculated according to the formula of power P=electricity ÷24 hours.

(3) Test data:

1. Measurement time: 15 hours from September 20 to 15:00 on September 21, a total of 24 hours.

2. The base of the single-phase active energy meter is 0.3 degrees.

3. Terminating the meter reading:

Qingdao Franco 6U-60W high frequency energy saving lamp = 2.09 degrees

400W metal halide lamp = 9.73 degrees.

4. Calculate the actual power:

Qingdao Franco 6U-60W high frequency energy saving lamp = ( 2.09 degrees - 0.3 degrees) ÷ 24 hours

= 1.79 degrees ÷ 24 hours = 74.5 W

400W metal halide lamp = ( 9.73 degrees - 0.3 degrees) ÷ 24 hours

= 9.43 degrees ÷ 24 hours = 393 W

(4) Regarding the use of a single-phase active energy meter to measure the active electrical power of an electronic energy-saving lamp (electronic ballast fluorescent lamp), the technical mechanism of the forward error is analyzed.

1. Electronic energy-saving lamp (electronic ballast fluorescent lamp), the power terminal is a bridge rectifier + electrolytic capacitor filter circuit. The input voltage waveform is a continuous sine wave, and the input current waveform is a discontinuous narrow pulse wave corresponding to the peak value of the voltage waveform.

2. Because the input current waveform is a discontinuous narrow pulse wave, the power factor at the power input terminal is relatively low. And the phase property of the power factor is capacitive.

3. Just because the input current waveform is a discontinuous narrow pulse wave, and the phase property of the power factor is capacitive. At the power input end, only the active current component, the harmonic current component, and the direct current component are included. There is no reactive current in the sense of an inductive grid.

4. Just because the input current waveform is a discontinuous narrow pulse wave, the electrical power at the input of the power supply contains three power components. Namely: active power component; harmonic power component; DC power component.
5, power input:
The active power component, the single-phase active energy meter can accurately measure.
Harmonic power components, single-phase active energy meters cannot be metered. However, the harmonic power component will interact with the harmonic power of the grid, which will have an error on the measurement of the single-phase active energy meter. In most cases, the direction in which the error occurs is: positive error. The DC power component, single-phase active energy meter cannot be metered. The direct error is directly measured by the metering of the single-phase active energy meter.
6. The harmonic power component and the DC power component of the power input terminal generate a range of positive error for the measurement of the single-phase active energy meter. It is related to the actual factors such as the energy of the odd-even harmonic power in the grid, the magnitude of the voltage spike, the length of the sustain period, and so on. In general, it is 10% - 25%.
7. The influence of the positive error determined by the light load characteristics of the single-phase active energy meter (for the mechanism, please see the other analysis).
8. The number of powers measured at this site = 74.5 W, which is significantly greater than the rated power value of 60 W. There are also factors affecting the actual field voltage fluctuations and high values.

Qingdao Frank 6U-60W high frequency energy-saving lamps, rated power of 60 W, a rated current of 270 m A. Actual current partial product is negative, about 250 m A.

In this analysis, the number of powers measured in the field is still used = 74.5 W.
