New gas sensors enable fault early warning for electrical equipment

New gas sensors enable fault early warning for electrical equipment

A high-tech enterprise has developed a new type of gas sensor suitable for electrical equipment. Based on nanomaterial sensing technology, this sensor can quickly detect multiple characteristic gases such as SF6 and H2, with a detection sensitivity reaching ppb level. When deployed inside equipment such as switchgear and GIS, it can real-time monitor the internal insulation status of the equipment and immediately trigger an alarm upon detecting abnormal gas concentration, providing an important basis for fault diagnosis of electrical equipment.

Smart grid construction is accelerating, improving power system reliability

Smart grid construction is accelerating, improving power system reliability

With the development of digital technology, the construction of smart grids in China is accelerating across the board. Power companies in many regions are actively deploying smart meters, sensors, and communication networks to build an intelligent management system covering all aspects of power generation, transmission, distribution, and consumption. By real-time monitoring of grid operation status, the smart grid can quickly locate faults and automatically isolate them, shortening power outage times by over 70%. In addition, it can achieve precise allocation of power resources and optimize the user's power consumption experience. It is expected that by the end of 2025, the coverage rate of smart grids in major cities nationwide will exceed 90%.

Electrical enterprises collaborate with universities to jointly research new energy storage technology

Electrical enterprises collaborate with universities to jointly research new energy storage technology

To address the intermittency of renewable energy, multiple electrical enterprises and universities have engaged in deep cooperation to jointly develop new energy storage technologies. Both parties will focus on areas such as lithium-ion batteries, flow batteries, and hydrogen storage, and through industry-academia-research collaboration, overcome challenges such as low energy density, high cost, and short lifespan of energy storage systems. Currently, some projects have achieved phased results, with the energy density of new energy storage materials increasing by 40% compared to traditional materials. Once these technological achievements are industrialized, they will effectively enhance the power system's peak-shaving capability and promote the consumption of clean energy.
