Recently, the AVR series dynamic voltage restorer products independently designed, developed and produced by avic-tec (Xiamen) Power Technology Co., Ltd. (hereinafter referred to as "avic-tec") have passed the full-scale test of the national quality supervision and Inspection Center for electronic control distribution equipment.

This type test is mainly carried out in accordance with dl/t 1229-2013 technical specification for dynamic voltage restorer, gb/t 15576-2008 low voltage complete reactive power compensation device, dl/t 1216-2013 technical specification for static synchronous compensation device of distribution network, GB 7251.12-2013 low voltage complete switchgear and control equipment Part 2: complete power switchgear and control equipment and other relevant standards. In the inspection process of more than 20 days, the national quality supervision and inspection center of electronic control distribution equipment has carried out perfect performance verification, long-time full load temperature rise test, 48 hour humidity and heat resistance environmental test, EMC electromagnetic compatibility (surge, group pulse, radiation immunity, conducted immunity, electrostatic discharge) and other related tests on AVIC AVR dynamic voltage restorer. The test results meet and are superior to the technical indicators of relevant clauses of the standard.

AVIC Tec AVR series dynamic voltage restorer system is a new generation of power quality solution developed by our company with a large amount of R & D resources in recent years. The power of a single machine is from 10KVA to 1600KVA, which has a good governance effect on Voltage Sag (commonly known as "power swing"), voltage surge, short-term interruption, etc., and supports 100% drop of three-phase input voltage. In addition, in order to meet the application needs of different regions, different industries and different occasions, the input and output line voltage of AVR series dynamic voltage restorer supports 208/220/380/400/415/460/480v customization, which does not require users to configure additional voltage rise and fall transformers. Compared with conventional high-power On-line UPS, dynamic voltage restorer works in bypass mode when the power grid is normal, with small standby loss and efficiency ≥ 99%, which can significantly reduce long-term operation costs and improve equipment operation life and reliability; In case of power quality problems, the equipment can complete the switching within 2ms-5ms to meet the needs of most equipment.

Avic-tec AVR series dynamic voltage restorer uses high-quality super capacitors as energy storage components, and independently develops a multi-level high-precision super capacitor management system, which realizes the fine management and application of super capacitors, ensures that the system can charge and discharge up to 1million times, and truly achieves daily maintenance free. Thanks to the excellent performance of super capacitor system, the life cycle of energy storage components and dynamic voltage restorer host in the whole AVR system has reached the same level, which solves the problem that users need to replace lead-acid batteries many times in the life cycle of electric energy treatment equipment. At the same time, avic-tec AVR series dynamic voltage restorer can also be used together with flywheel energy storage, and relevant prototype trials are being carried out.

The National Center for quality supervision and inspection of electric power distribution equipment is a laboratory approved by the China conformity assessment commission and authorized by the certification authority. Founded in 1985, the "testing center" is a domestic experimental institution engaged in quality monitoring of electric power distribution equipment, new product testing, acceptance, product certification and quality arbitration inspection. It has obtained the laboratory accreditation authorization (cans) of China National Accreditation Commission for conformity assessment, and has a series of quality inspection related certification qualifications such as quality supervision and inspection agency certification qualification (CAL), metrology certification qualification (CMA), It has more authority and credibility in the industry.
