To escort the safety of electricity consumption, State Grid Hunan Electric Power Research Institute conquers oil chromatography online monitoring technology
The power transformer is one of the most important electrical equipment in the power system, and its operating state directly affects the safe and stable operation of the entire power system. The establishment of a power transformer oil chromatography online monitoring system is one of the effective means to reduce the transformer accident rate. Electricity is an indispensable strategic resource in my country's economic development. With the continuous acceleration of my country's modernization process, people's demand for electricity is constantly expanding. Therefore, the smart grid is also developing and expanding. The rapid development of the substation industry. On June 6, the new oil chromatography online monitoring device independently developed by State Grid Hunan Electric Power Research Institute was installed and commissioned in Qingdao 110kV Century Substation and officially put into operation. The new technology has been successfully implemented outside the province, which means that the new oil chromatography online monitoring technology has been recognized by the industry, which can greatly improve the intelligent management and control level of power grid equipment and ensure the safety of electricity consumption. In recent years, State Grid Hunan Electric Power has actively promoted the digital transformation of the power grid, carried out intelligent upgrading and transformation of substations, and applied a large number of new technologies such as new oil chromatography online monitoring devices to improve the level of intelligent equipment management and control, and accelerate the construction of a modern intelligent inspection system. The new oil chromatography device has been tackled by the doctoral team of the Electric Power Research Institute for 4 years. The self-developed automatic carrier gas unit solves the problem of frequent maintenance after the device is put into operation. The intelligent algorithm developed on the basis of a large amount of operating data effectively improves the accuracy of the monitoring data. It realizes automatic status diagnosis and optimizes components and control strategies to improve the long-term operation reliability of the device. It has the advantages of maintenance-free, high precision and high reliability. At present, more than 70 sets of the device independently developed by the Electric Power Research Institute have been put into operation in more than 40 substations in Hunan Province, covering±800 kV, 500 kV, 220 kV, 110 kV and other voltage levels, the operation of the device is excellent, providing strong technical support for ensuring that residents can use electricity with confidence during peak summer and electricity peak periods. Currently, enter“fourteen five”During the period, driven by the synergy of market demand, technological innovation and public policies, the scale of my country's digital economy development will be further expanded. As a field closely related to people's life, the power grid is also accelerating the pace of progress to adapt to the development of the intelligent society. Substations are the core link of the power grid. The emergence of smart substations has changed the operation and maintenance mode of traditional substations, realized the transformation of substations to be intelligent and green, and accelerated the construction of substations.“Unattended + centralized control”The transformation and upgrading of the new mode of substation operation and maintenance has also promoted the development of smart grids.
The Heat Contact Machine GT-C101 is a specialized testing instrument designed for evaluating the heat resistance and thermal protective performance of gloves, protective clothing, and other heat-resistant materials used in high-temperature environments. In industries such as smelting, casting, welding, and glass manufacturing, workers are frequently exposed to intense heat, making accurate testing of contact heat resistance essential for ensuring safety and compliance.
GT-C101 simulates real working conditions by measuring heat transfer delay and thermal transmission under instant contact with high-temperature surfaces. Fully compliant with EN 407, EN 702, and ISO 12127-1 standards, this machine provides precise, repeatable data for manufacturers, laboratories, and research institutions. With high-temperature capability up to 500°C, advanced calorimetry, digital monitoring, and adjustable contact speed, the Heat Contact Machine GT-C101 is an indispensable tool for developing and certifying next-generation PPE and heat-insulation materials.
