Product Detail

Model and Its Meaning

Overview

🛡️

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.

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.

Frequently Asked Questions (FAQ)

❓ What does the "V" type wiring configuration mean in the JSZV1 series?

The "V" type wiring configuration means that two single-phase voltage transformers are combined using epoxy resin casting to form a unified unit connected in a "V" arrangement. This design provides reliable voltage measurement and monitoring while maintaining a compact and stable structure suitable for indoor installation.

❓ What accuracy levels are available for the JSZV1-3R, JSZV1-6R, and JSZV1-10R models?

All three models — JSZV1-3R, JSZV1-6R, and JSZV1-10R — are available in accuracy levels of 0.2 and 0.5. The 0.2 accuracy level offers a rated output of 30 VA, while the 0.5 accuracy level provides a rated output of 50 VA. All models share a limiting output of 500 VA.

❓ How is the fuse replaced in the JSZV1 series voltage transformer?

The fuse is installed inside the primary terminal for short-circuit protection. To replace it, the power must first be turned off. Once the power is disconnected, the primary external wiring can be removed quickly and conveniently, making the fuse replacement process safe and straightforward.

❓ What are the recommended ambient temperature conditions for operating the JSZV1 series?

The JSZV1 series voltage transformers are designed to operate within an ambient temperature range of -5℃ (minimum) to 40℃ (maximum). Additionally, the average daily temperature should not exceed 30℃ to ensure reliable and stable long-term performance.

❓ Why is epoxy resin casting used in the construction of these voltage transformers?

Epoxy resin casting is used because it provides excellent insulation properties, strong resistance to humidity and dust, and high mechanical strength. This material helps the transformer maintain stable performance under varying indoor environmental conditions, reducing the risk of insulation breakdown and improving overall equipment reliability and safety.

❓ In which types of environments can the JSZV1 series voltage transformers be used?

The JSZV1 series is designed exclusively for indoor installation in environments with no serious atmospheric pollution. They are suitable for a wide range of applications including industrial, commercial, and residential power systems, where they play a key role in power monitoring, measurement, and control tasks.
