On January 10, the Science and Technology Achievement Appraisal Meeting of the "Water - Immersion - Proof Medium and Low - Voltage Complete Equipment" project organized by the China Electricity Council successfully concluded in Shenzhen.
This appraisal meeting gathered an authoritative appraisal committee with Rao Hong, an academician of the Chinese Academy of Engineering, as the team leader. The committee consisted of ten senior experts from units such as China Southern Power Grid, Xi'an Jiaotong University, and South China University of Technology.
After rigorous review and questioning, the committee unanimously agreed that the project features advanced technology and remarkable innovation, reaching the international leading level as a whole. It provides key equipment support for enhancing the ability of the distribution network to resist extreme disasters and has great value for promotion and application.
Facing the Pain Points of Disasters: Innovative Achievements Undergo Authoritative Inspection
In the face of the severe threat of floods caused by extreme weather to power facilities, the "Water - Immersion - Proof Medium and Low - Voltage Complete Equipment" jointly developed by Longhua Power Supply Bureau of Shenzhen Power Supply Co., Ltd. and Guangdong Zhongpeng Electric Co., Ltd. came into being. At the appraisal meeting, the project team systematically demonstrated its core technology and application results to the expert group:
01 Highest - level Protection
The entire set of equipment achieves an overall IP68 protection level and can operate continuously and safely for more than 24 hours in an environment with a water depth of 3 meters, fundamentally solving the power outage problem caused by flooding in the substation.
02 Intelligent Monitoring and Operation and Maintenance
Integrating intelligent measurement and control units and the Dianhong IoT system, it realizes real - time perception and remote intelligent control of the equipment operation status and the station environment (water immersion, temperature, smoke, etc.), greatly improving the operation and maintenance efficiency and emergency response speed.
03 Full - range Solution
It covers key equipment such as medium - voltage switchgear, dry - type transformers, and low - voltage switchgear, forming an integrated water - immersion - proof complete equipment system. It has been successfully put into operation in multiple flood - prone areas, verifying its excellent reliability and stability.
Leading Industry Standards and Laying a New Foundation for Grid Safety
The successful passing of the national - level science and technology achievement appraisal marks the formal recognition of this technology by the highest industry authority. The appraisal experts unanimously pointed out that this achievement fills domestic and international gaps. Its superior protective performance provides important technical basis and practical models for the formulation and upgrading of relevant industry standards. The promotion and application of the project will have a profound impact on ensuring the power supply safety of urban lifelines, enhancing the resilience of the power grid, and serving the national disaster prevention and mitigation strategy.
The successful convening of this appraisal meeting not only fully affirms the innovative work of the project team but also indicates that our country has stepped into the forefront of the world in the field of water - immersion - proof power equipment. In the future, this technology will provide a solid guarantee for building a safer and smarter modern distribution network and safeguarding the lights of thousands of households.
