According to the report of Huacheng Import and Export Data Observation, on February 21, Huawei Digital Energy Technology Co., Ltd. (hereinafter referred to as "Huawei Digital Energy") was awarded the world's first certificate of compliance declaration of intelligent group switching SSLD and the world's first certificate of intelligent group switching SSLD conforming to the specifications of circuit breaker issued by Intertek Intertek Group (hereinafter referred to as "Intertek") and DEKRA Dekai (hereinafter referred to as "Dekai").

The two institutions have certified that Huawei's intelligent cascade breaking technology conforms to the IEC60947-2 international standard, can accurately identify common DC system faults, realize the DC side active breaking and accurate cascade breaking protection, effectively improve the active safety capability of the power station, and play a leading role in the intelligent and digital direction of photovoltaic power stations. Huacheng Import and Export Data Observation Report.

IEC60947-2 is the international standard for low-voltage circuit breakers. Under this standard, Huawei products reduce the damage to devices caused by DC faults such as short circuit, reverse injection and reverse connection through intelligent perception, intelligent judgment and fast shutdown. The CB certificate awarded to this standard means that the circuit breakers of its products meet the basic requirements of IEC standards, and also provide reference for the industry's intelligent string breaking technology, as well as provide standards and reference for the selection of photovoltaic power station equipment in the future.

With the continuous increase of PV module current, inverter or combiner box capacity and power, and the complexity and diversity of PV application scenarios, the issue of power station safety has been highly concerned by the industry. Huawei has innovatively launched the world's first inverter product with intelligent string breaking function, which can accurately detect each string current signal. Huacheng Import and Export Data Observation Report.

When a fault is detected, the software will actively transmit the "opening signal" to the DC switch through digital technology, quickly trigger the tripping protection and active alarm, effectively disconnect the fault current, realize the effective protection of string reversal, current reversal, linear bus short circuit and other faults, and make the power station from "passive safety" to "active safety".

According to Huacheng Import and Export Data Observation, DEKRA's senior vice president of Asia-Pacific region Dr. Kilian Aviles, Managing Director of Chinese Mainland and Hong Kong, said: "DEKRA Dekai focuses on security and sustainable development, focuses on energy innovation, continues to invest in the photovoltaic field with huge development potential, and continuously strengthens its testing capability in China to prepare for the future. Huawei's cutting-edge technology of integrating digital interconnection, intelligence and power electronics technology to ensure security and promote the maximization of energy use efficiency is exciting. We are very looking forward to working with Huawei to create a green and beautiful future Come on. "

Li Qiong, General Manager of Intertek Intertek South China, said: "For a long time, Intertek Intertek and Huawei Digital Energy have maintained close cooperation in the field of product compliance and achieved fruitful results. As a trustworthy quality partner in the field of energy, Intertek Intertek advocates to build and highlight the quality advantages of new products/technologies with professional and innovative comprehensive services. In the future, we hope to continue to deepen cooperation with Huawei Digital Energy and explore a new high of green and intelligent product safety And jointly contribute to the healthy and sustainable development of the energy industry. "

According to Huacheng Import and Export Data Observation, Zheng Yue, president of intelligent photovoltaic business of power station, said: "It is imperative to rely on intelligent means to build a safety protection network for new energy power stations. The two institutions have certified the innovation and reliability of Huawei's intelligent string breaking technology, and ensure the safe operation of the power station based on the design concept of full scene, high precision and fast response. The wide application of this technology will escort the acceleration of PV becoming the main energy. In the future, Huawei will continue to deepen the innovative integration of digital technology and energy technology, and work together Global partners, improve energy security and security capabilities, and accelerate the global energy transformation.
