In modern energy systems, the performance of current converters directly depends on the energy measurement accuracy and the coherence protection time. Independently developed by Wenzhou Heyi Electric Co., Ltd., is a professional-grade product suitable for the needs of high accuracy, high reliability and worldwide compliance. As the main model of Heyi Electric, the SDH series window type current transformer adheres to the concept of "a single construction used worldwide". Thanks to its hole design and excellent electromagnetic properties, this window type current transformer is the main connector for capturing accurate energy data in various become scenarios. The product achieves compatibility with the double frequency 50 Hz / 60 Hz, and the SDH current transformer one of the specifications can meet the requirements of European and American systems and simplify the purchasing pressure of a cross-border project.
1. Research Scenarios and Accuracy Tests
As a low voltage current transformer, the SDH series shows exceptional value in the field of scientific research and precision testing.
1.1 Laboratory for Power Electronics and Test Platform Type
When testing transformer type and testing high power supplies, accurate detection and analysis of current signals with different frequencies and waveforms are required. The SDH series is characterized by a high accuracy of level 0.2 and a wide measuring range from 5 to 120 wt. % off. It maintains an excellent line even under non-particle conditions with high harmonic content and offers real waveforms for precision tools such as energy analyzers. The fully enclosed design effectively protects against electromagnetic interfaces and the design of a large window facilitates the frequent exchange of laboratory goods and significantly improves experimental performance.
1.2 Calibration laboratory and standard control
In a processor calibration device, the processor used as a standard comparator must have a very high stability and a very low phase error. The SDH series uses a heat-treated silicon steel core in high vacuum with low phase angle deviation and fully meets the stringent requirements for traceability accuracy of current transformer for energy meters used in the measurements. It can provide accurate up-to-date references for on-site value transfer and calibration.
2. Transport infrastructure and rail transport scenarios
2.1 Monitoring of rail energy supply
On subway substations and light rails, the SDH Series window type current transformer can be mounted directly on the Minister Bus for AC Low Voltage Distribution, to control the second side of the station carrier and the current of the ventilation and lighting system in real time. The UL94-V0 fire protection skin and the fully insulated construction work in very damp, stable in dusty and vibrating tunnel environments for a long time and provide continuous data for remote monitoring and fault warning.
2.2 Port stations and land facilities Airports
In the coastal network of the port and the supply of the airport bridge, frequent switching on and off of high energy loads is tested for excessive charging capacity of the transformers. SDH series has a maximum current coverage of 10000A, and the model of large window can accommodate many parallel cables, to meet the needs of high current control of offshore power bodies. The wide temperature range and the performance of the salt sprayer guarantee long-term reliable operation in coastal environments with high humidity.
3. Industry-specific processes and harsh environmental scenarios
3.1 Electrochemical and metal industry
In processes such as electrical aluminum and electrical coatings, the secondary current of transducers can reach several thousand amperes and accompany corrosion gases. The large window model of the SDH series achieves contactless isolation of high current, thus avoiding connection resistance and hot spots. The corrosion resistance and fully sealed construction of PBT effectively prevent acidic gases and guarantee long-term stability in harsh chemical environments.
3.2 Mining and energy distribution in heavy industry
The underground distribution of energy in the mines requires strong vibrations and high concentrations of dust. SDH Series window type current transformer contains a fully enclosed flame retardant layer to prevent dust from penetrating, and the screw pressure stations maintain a reliable connection under vibration. It can be installed directly in explosion-proof distribution containers, to ensure ongoing monitoring of major loads such as duct pumps and fans and to assist in the online diagnosis of equipment condition.
Wenzhou Heyi Electric has been deeply involved in the field of current processors for more than 20 years and their products have passed international certificates such as TUV. The SDH Series window type current transformer provides strong support for the safe operation and improvement of energy efficiency of global energy systems with excellent Performance and wide adaptability to different scenarios.
