For complete suppliers and engineering service providers in the field of energy electronics and industrial automation, the choice of a suitable protection current transformer directly affects the Fault detection in low-voltage distribution systems, the reliability of protection procedures as well as the operating and maintenance costs in the long term. Introduced by Heyi Electric, the HPT series low voltage protection current transformer is specially developed for continuous protection and short circuit fault detection.
1. What is the protection current transformer? HPT Series Provides answers
The HPT series strictly meets international standards such as IEC61869 2, EN60044 1, VDE0414 44 1 and GB1208 2006. Its built-in construction and multiple opening sizes (40 mm to 135 mm) make it very suitable for mounting in various switches. As an excellent protection CT for switchboard, the HPT series can adapt to complicated distribution scenarios where the rods run through one or more buses. The casing is made of imported flame-retardant polycarbons and 140°C, the iron core is aimed at a cold-driven silicon steel strip, uses the secondary durability of the high-performance electromagnetic lines of the mine, all of which guarantee the stability and safety of the protection CT for switchboard during long-term work.
1.1 Why is HPT the ideal protection CT for switchboards?
The HPT series has been specifically developed for a limited interior area and different shapes of bus basins in exchangers. HPT can supply the appropriate opening specifications for both small buses of 40 mm x 10 mm and large buses of 135 mm x 10 mm. Engineering service providers can safely choose this protection CT for switchboard in accordance with the complete switchgear or MCC (motor control center). Stainless steel connections and laser glued names increase the convenience of on-site assembly and maintenance.
2. Accurate compliance: reliable choice for relay protection current transformer 5A
In low voltage protection systems, transmitters and motor protection units generally require an input current signal of 5A. The HPT series offers many secondary outputs including 5A, 1A, 0.1A, and 0.05A, although the 5A specification is a typical relay protection current transformer 5A. Whether it is a wide current range of 200A to 6300A, an accuracy level of 5P/10P, and an accuracy limit coefficient of 10/15/20, for further protection of 5A, this relay protection current transformer 5A can generate accurate current signals for further protection under overload and short circuit conditions.
2.1 Why do engineering service providers prefer this relay protection current transformer 5A?
When repairing old switches or constructing new motor control centers (MCCs) Engineering service providers are often faced with problems such as different power conditions and a narrow assembly area. The HPT series offers a full range of switching ratios from 150/5A to 5000/5A with a maximum output of 30VA, which can be adapted directly to most protective correspondence on the market. Therefore, choosing this relay protection current transformer 5A can greatly reduce the complexity of selection and improve the performance of project delivery.
3. Advantages of CT for overcurrent protection system
Like CT for overcurrent protection systems, the HPT series has clear advantages. It supports the opening sizes of multibuses, allowing 13 buses to travel through at the same time, making it very suitable for the distribution of multibuses. If you need to configure a CT for overcurrent protection system, the HPT series offers a complete selection of current ratings of 400A, 800A, 1600A and even 6300A with a maximum power of 30VA.
3.1 Ease of assembly and maintenance of CT for overcurrent protection system
Due to the built-in and lightweight construction of the HPT series, the flameproof and high temperature resistant shell materials as well as the various mounting options make the CT for overcurrent protection system better suited for on-site mounting and the Later maintenance. Whether it is the intelligent conversion of newly assembled electrical containers or old switches, HPT can be quickly used as a CT for overcurrent protection system, thereby reducing downtime.
4. Summary: Why HPT series is a reliable protection current transformer
In short, the HPT series low voltage protection carrier is not only a reliable current protection carrier, but also a protection solution, the accuracy, Combines performance and flexibility of assembly. For purchasing executives and engineers who choose various low voltage distribution projects, it is worth including this product in their favorite library. If you need a test sample or assistance in the selection, do not hesitate to contact us at any time.
