JSZV1-3,6,10R Series Indoor Epoxy Resin Cast Three‑phase Voltage Transformer PT 10‑12kV for Metering, Measurement and Relay Protection for RMU Ring Main Unit & Medium Voltage Switchgear

Model and its meaning

Summarize

Voltage transformers feature a high level of safety protection, designed to effectively reduce potential risks, especially considering the frequent activity of people indoors, where their safety design is more comprehensive. To ensure safety during use, these transformers often employ a closed or semi-closed structure. This design significantly reduces the number of exposed live parts, thereby effectively reducing the risk of accidental contact and ensuring the safety of operators.

The insulation design of the voltage transformer is carefully considered to withstand the humidity and dust that may occur indoors. This adaptable design not only improves the reliability of the equipment but also avoids safety accidents caused by insulation breakdown. By using high-quality insulation materials and advanced insulation technology, the voltage transformer can maintain stable performance under various environmental conditions, ensuring its safe operation in the power system.

 In practical applications, this type of voltage transformer with a high level of safety protection can effectively protect equipment and personnel, reduce the probability of accidents, and improve the safety and stability of the entire power system. Whether in industrial, commercial, or residential environments, the safety design of voltage transformers provides users with greater assurance, enabling them to play a crucial role in power monitoring and control.

Technical parameter

Structure and characteristics

This series of voltage transformers is composed of two single-phase voltage transformers using epoxy resin casting as a whole to form a ' V ' type wiring. The primary winding has a fuse for short-circuit protection. The fuse is installed inside the primary terminal. When replaced, in the case of power failure, it is very convenient and fast to remove the primary external wiring. There are grounding bolts and four mounting holes for installation on the product bottom plate.
