At present, the company actively responds to the country’s call for energy conservation and produces the QJD1-S power (filter, compensation) energy saver, which saves electricity from the transformer.

The QJD-S series power (filter, compensation) energy saver (patent acceptance number: 200520115839.6) researched and developed by Hangzhou Qiandian Electrical Equipment Co., Ltd. applies the principle of electromagnetic balance technology and is targeted at three-phase four-wire To control system voltage imbalance, neutral point drift, high-order harmonics and other chronic diseases caused by non-linear loads in low-voltage power supply networks, new technologies and new materials are used to scientifically and reasonably manage them, effectively improving power quality and reducing Reduce energy consumption, comprehensively saving 10-25%. And according to users in various fields and different load properties (for example: light textile, chemical industry, metallurgy, intermediate frequency furnace, rectifier device, welding equipment, computer, etc.), targeted personalized design is carried out to meet the needs of users. It has a very positive significance for promoting a conservation-oriented and environmentally friendly society and alleviating energy shortages and power cuts.

The wide range of uses of this product:

Generally, ordinary power savers can only save power on a certain device or a lighting system, and cannot be used as a comprehensive power saver for the power system. electrical devices. The QJD-S series power (filtering, compensation) energy saver is installed in the power supply circuit on the low-voltage side of the distribution transformer. It uses balanced voltage, harmonic control, and reactive power compensation to achieve the effect of improving power quality and comprehensively saving energy. It can be widely used in various fields of the national economy.

2 Product performance:

1 This product is based on the mature electromagnetic balance principle to achieve the purpose of suppressing harmonics, balancing voltage, improving power quality and saving energy. It can control various indicators such as the power supply voltage of electrical equipment to the best power quality state, and comply with the GB-T14549 "Power Quality Requirements" standard.

2 Ability to respond promptly to sudden changes in grid voltage and current due to load factors to ensure balanced changes in power usage conditions. It also reduces the flicker of line voltage and current caused by factors such as operation or failure of the power system, ensuring the stability of the system.

3 Improve the three-phase unbalanced power supply voltage to reduce the negative sequence and zero sequence components generated by the unbalanced power supply. Absorb high-frequency peak wave pulses of voltage and current to keep the voltage stable. This prevents damage to electrical equipment and lighting appliances caused by excessive or low voltage.

4 Due to the large amount of harmonic currents generated by non-linear loads such as metallurgy, chemical industry, rectifier equipment, intermediate frequency electric furnaces, and frequency conversion devices in the system, injected into the system. Harmonic voltages are generated, superimposed on the fundamental wave of the power grid, causing distortion of the grid voltage waveform, reducing power quality, causing damage to power supply equipment and electrical equipment, affecting the accuracy of electricity metering, failure of relay protection, and harmonics causing damage to the power grid. Inductive loads cause overvoltage, and capacitive loads cause overcurrent, which endangers the safety of electricity. The QJD-S series power energy saver is equipped with a device to control high-order harmonics in the system loop, which can ensure the voltage and waveform quality of the power grid and comply with national standards. This reduces the impact of harmonics on electrical equipment, making the metering device more accurate while saving electrical energy. Examples show that the 3rd, 5th, 7th, 9th, 11th and above harmonics are eliminated, improving the system voltage waveform and improving power quality.

5 QJD-S series power (filter, compensation) energy saver also has the function of improving power factor.

Three Product Features

1 QJD-S series power (filter, compensation) energy saver has no mechanical transmission components, so there is no mechanical vibration and no electromagnetic noise.

2 The QJD-S series power (filter, compensation) energy saver has no electronic components, IC circuit devices or mechanical wear, and has high reliability.

3 The insulation material grade of the QJD-S series power (filter, compensation) energy saver is Class H, which can withstand temperatures up to 180°C. By selecting high-quality ferromagnetic materials and insulation materials and good production technology, This ensures product life of more than 30 years.

Four social benefits and energy-saving effects

“Energy conservation and development should be paid equal attention to, and energy conservation should be given top priority” is our country’s energy policy. Saving energy is also protecting the environment and is the key to realizing the goal. Concrete actions for the Sustainable Development Goals. It is also an unavoidable social responsibility and mission of the manufacturing industry. According to the CO2 emission standards, it can be seen that every 1kW.h of electricity saved can reduce 0.13KG CO2 emissions. By saving electricity and reducing the emission of harmful gases, the global greenhouse effect can be reduced and the earth where we humans live can be beautified. Therefore, saving electricity is beneficial to the country. Benefiting the people is the common responsibility of the whole society.

The installation of QJD-S series power (filter, compensation) energy savers can bring obvious economic benefits to enterprises and groups, and improve the efficiency of use. While protecting the electrical environment, it also saves electricity bills. According to tests: Under normal circumstances, users who use 630kVA-2500kVA distribution transformers can achieve a comprehensive power saving rate of 7%-15% after installing this product on the low-voltage side.

For example, a 1600kVA distribution transformer carries a comprehensive load of 1200kW, and the annual average load rate is 60%. After installing the QJD-S series power energy saver, the comprehensive power saving is 12.5%, and the electricity price is 0.70 yuan/kW. .h for calculation: (The investment payback period of the product generally does not exceed 1.5 years)

One-year power saving (1200×0.6×8760×0.70×0.125)=551,880 yuan.
