Combined Instrument Transformer

Combination transformer is a power equipment that combines current transformer and voltage transformer into one, which can achieve accurate measurement and signal conversion of current and voltage simultaneously. It adopts a compact integrated design with high integration, effectively saving installation space. With advanced electromagnetic induction technology and high-quality material manufacturing, it can provide accurate and reliable current and voltage signals for the power system, widely used in fields such as power metering, monitoring, and protection.

Product Advantages and Features

1. Highly integrated and space saving: By combining current transformers and voltage transformers into one, the volume can be reduced by about 30% compared to installing two types of transformers separately, effectively saving the internal space of distribution cabinets and other equipment, making installation and layout easier.

2. High precision measurement: using advanced winding technology and high-quality magnetic materials, the current measurement accuracy can reach 0.2S level, the voltage measurement accuracy can reach 0.2 level, and the measurement error is extremely small within the rated range, providing accurate data for power measurement.

3. Excellent stability: Using special shielding and insulation technology, it can effectively resist external electromagnetic interference, with an insulation level of 35kV, ensuring stable operation in complex environments and guaranteeing the stability of signal output.

4. Economically efficient: Integrated design reduces installation accessories and construction volume, lowering procurement, installation, and maintenance costs. At the same time, its long-life design has an average trouble free operation time of over 100000 hours, reducing replacement frequency and further saving costs.

5. Strong adaptability: It can adapt to a wide temperature range of -40 ℃ to+70 ℃, as well as different humidity environments, and can work stably under various harsh natural conditions to meet the needs of power systems in different regions.

Application Scenarios

1. Urban power distribution network: Installed in urban switch stations, distribution rooms, etc., it monitors and measures the current and voltage in the power distribution network in real time, provides a basis for power allocation, and ensures stable power supply in the city.

2. Industrial plant area: used to monitor the operating current and voltage of large equipment in the factory, detect abnormalities in a timely manner, prevent equipment failures, and ensure smooth industrial production.

3. Rural power grid renovation: Due to its high integration, easy installation, and strong adaptability, it plays an important role in rural power grid renovation projects, helping to upgrade and stabilize the operation of rural power systems.
