Products Advantages
Excellent insulation performance: The fully enclosed epoxy resin casting structure provides high insulation strength for the transformer, effectively preventing internal circuits from contacting the external environment, thus preventing leakage, discharge, and other problems that may affect the normal operation and measurement accuracy of the equipment. Furthermore, this insulation structure is moisture-proof and anti-fouling, adapting to a variety of complex operating environments and maintaining stable performance even in harsh climates and polluted environments.
High Precision: Measurement accuracy is crucial for functions such as energy metering, voltage monitoring, and relay protection. During the design and manufacturing process, the JDZX9-35 voltage transformer rigorously controls the material selection and processing of key components such as the core and windings. This allows the device to accurately convert high voltage to low voltage, providing reliable data support for power system metering, monitoring, and protection.
Compact structure, small size, and light weight: The compact overall structure and the mounting plate at the bottom facilitate installation and fixing, making it easy to deploy in places with limited space, such as substations and distribution rooms. Its light weight also facilitates operation during transportation and installation, reducing construction difficulty and labor costs.
Safe and reliable operation: When excited at rated voltage, this type of transformer can withstand an external short circuit of one second without damage. It has high short-circuit tolerance and can maintain stable performance when a power system failure occurs, avoiding more serious power accidents caused by transformer failure and ensuring the safe operation of the power system.
Easy to maintain: The transformer does not require special maintenance, only regular cleaning of surface dirt is required, which reduces maintenance costs and workload.
The fully insulated structure has strong applicability: The fully insulated structure makes the transformer not only suitable for general power systems, but also can be used normally in some special occasions with high insulation requirements, such as high altitude areas and humid environments, thus expanding its application range.
Good electromagnetic compatibility: It can work stably in complex electromagnetic environments and is not affected by external electromagnetic interference, ensuring the accuracy and reliability of measurement results. At the same time, it will not cause electromagnetic interference to other power equipment.
Product Application
Power systems (substations, distribution cabinets).
