功能描述

With the rapid development of our national economy, power load increased sharply, especially the growing impact and nonlinear load capacity, makes the grid waveform distortion and phase balance of power quality problems. The company introduced the SD-PQ1100 power quality tester (hereinafter referred to as SD-PQ1100) is a high-performance multi-functional power quality testing and analysis equipment. Using DSP+ARM+CPLD kernel, 5.5 "big screen LCD (320 * 240 dot matrix) display, make the structure more compact, more powerful, more convenient. Background management analysis software, function is rich, easy to operate.

儀器特點

2.1 measurement and analysis of the power quality of the power supply to the user side, the measurement and analysis of the frequency deviation, voltage deviation, three phase voltage to allow imbalance, power grid harmonics.

2.2 application of wavelet transform to measure the harmonic of non-stationary time varying signal.

2.3 the measurement and analysis of the power quality of the public power grid in different operation condition.

2.4 load fluctuation monitoring: timing recording and storage of voltage and current, active power, reactive power, apparent power, frequency and phase of power parameters change trend.

2.5 power equipment adjustment and operation process of dynamic monitoring, to help users solve problems in electric equipment adjustment and commissioning process.

2.6 test in power system analysis, circuit breaker transformer overheating, the motor burned, automatic device malfunction and failure.

2.7 test and analysis of reactive power compensation and filtering device in power system dynamic parameters and to make quantitative evaluation on its function and technical index.

2.8 portable, multi parameter, large capacity, high precision and modern signal analysis theory and the application of the SD-PQ1100 characteristics, can be widely used in power transmission and distribution, power electronics, motor etc..


技術參數

3.1 safe and reliable

Input voltage with high voltage isolation module (2000V, response time is less than or equal to 2 mu s, the input current using current clamp (0 ~ 50KHz. 0 ~ 5Arms) enable input and measurement system security isolation. This not only makes the SD-PQ1100 in the use of safe, reliable and convenient, but also greatly improve the anti-interference ability of SD-PQ1100.

3.2 easy to use

Portable structure, small size, light weight, a person can carry equipment to the field test; built-in high-performance lithium battery, in the case of no external power supply can work continuously for 8 hours.

3.3 high precision

To meet the requirements of GB B level instrument. The harmonic of three-phase unbalance and adopt the baseline algorithm, approximate calculation, using high precision A/D (16), simultaneous sampling, sampling rate of 12.8 kHz.

3.4 software function

Using the DSP+ARM+CPLD kernel, fast processing speed, feature rich software, make SD-PQ1100 applicable to complex testing work and data processing, which greatly improves the testing efficiency and level.

3.5 communication interface

Power quality tester provides USB interface, convenient for storing data to U disk, communication data transmission and notebook computer.

3.6 real time print

Power quality measurement instrument configuration of micro thermal printer, can print real-time test data.

3.7 multi parameter testing

System frequency, harmonic, three-phase voltage unbalance, voltage deviation, fundamental voltage effective value and true effective value, fundamental current effective value and really effective value, fundamental active power, active power, fundamental visual quality 5 GB of parameters in power, 2-50 times harmonic, true power factor, etc. all the power.

3.8 real time harmonic data

The real-time judgment of current test voltage harmonics, harmonic current data in normal or exceed the standard.
