Why is Youbian's durable 10 kV current transformer the "eye" of the distribution system? Because in the 10kV distribution system, current transformers are the core equipment for ensuring the safety and accurate measurement of the power grid. They are like the "eyes" of the power system, converting high voltage and large current into low voltage and small current in proportion, providing stable signals for measurement, protection, and monitoring.
Are you troubled by difficult selection, unstable quality, and delayed supply? Do you need a current transformer that is compatible with 10kV switchgear and ring main unit, and meets both metering and protection requirements? Take a look at Youbian's 10 kV current transformer, it definitely meets your expectations.
10 kV current transformer (CT) is a high-voltage current conversion equipment suitable for 10kV voltage level, belonging to a type of electromagnetic transformer. Its core function is to convert high currents on the high-voltage side (such as 100A, 200A, 600A, etc.) into standard 5A or 1A secondary currents at a fixed transformation ratio, achieving electrical isolation between high-voltage systems and low-voltage measurement and protection circuits, while providing accurate current signals for energy metering, relay protection, and power monitoring.
This 10 kV current transformer adopts an epoxy resin fully enclosed casting insulation structure, with a brown epoxy resin shell as the main body. The P1/P2 terminals of the primary winding are led out with copper bars, and the secondary winding is output through a transparent junction box. The bottom is equipped with a stainless steel mounting plate, which is compatible with the installation size of standard switchgear.
The fully poured structure is oil-free, has no air gaps, is moisture-proof, anti fouling, and explosion-proof, and can operate stably in harsh environments ranging from -40 ℃ to+40 ℃ without the need for daily maintenance;
Youbian supports multiple accuracy levels such as 0.2S and 0.5 for measurement, 5P10 and 10P10 for protection, meeting the measurement and protection needs of different scenarios;
Can customize various ratios such as 5/5~3000/5A, suitable for various current specifications of 10kV distribution systems;
The iron core is made of high-quality silicon steel sheets, and the winding layout is reasonable, effectively reducing the influence of residual magnetism and ensuring measurement accuracy under high current impact;
Integrated structural design, compact size, directly installed in 10kV switchgear, ring main unit, and box type substation, saving cabinet space.
From the selection of iron core materials, winding to epoxy resin casting, every process of 10kV protective current transformers strictly follows the national standard GB 1208-2006 "Current Transformers". Before leaving the factory, 100% of the transformation ratio error, angle error, insulation withstand voltage, temperature rise and other comprehensive tests are carried out to prevent unqualified products from leaving the factory;
For special working conditions such as high altitude, high humidity, and high current, special insulation levels, transformation ratios, and installation dimensions can be customized to meet customers' personalized needs;
10 kV current transformer is made of high-quality epoxy resin and imported silicon steel sheets, which are anti-aging and corona resistant, with a service life of more than 30 years, and can benefit from one-time installation for life;
The secondary winding is designed with open circuit protection to prevent high voltage from endangering equipment and personnel safety, in compliance with power system safety regulations.
The energy metering of 10kV substations, distribution rooms, and box type substations provides accurate data for electricity bill settlement;
The overcurrent protection, quick break protection, and differential protection of 10kV switchgear and ring main unit ensure rapid tripping in case of power grid faults;
Real time monitoring of power grid operation status through distribution network automation system and smart grid current monitoring;
The 10kV power distribution system in factories, mines, and data centers ensures the safety of industrial production electricity;
The 10kV grid connected system of photovoltaic power plants and wind power projects is suitable for the special working conditions of new energy generation.
