1. Product Overview & Design Concept
WENZHOU HEYI ELECTRIC CO., LTD focuses on the research and manufacturing of transformer technology. Its core product, the DP series open close current transformer, solves the industry pain points of traditional transformer installation that require power outage and complicated construction with its revolutionary "open close" design. The DP series reflects the profound technological accumulation of the company and takes the users' demands as the center, aiming to provide customers with safety, efficiency, and flexibility in the field of current monitoring, which can be widely used in different harsh scenes, from energy management to industrial automation.
1.1 Dual innovation in appearance and structural design
The most significant advantage of the DP series is its innovative opening and closing shell structure. The product is made of high-strength flame-retardant engineering materials and is in accordance with PCA/U.94-V0 standards, ensuring the safety and durability of the products even in harsh electrical environments. Its compact external design but spacious internal windows allow the easy fitting of large cross-section cables or multiple parallel busbars, which greatly expands the application range.
1.2 Installation convenience and safety
As a real open close current transformer, the DP series focuses on supporting "continuous power installation". By using an exclusively designed double-screw fastening mechanism, operators can finish the closure and locking in minutes to guarantee firm magnetic circuit contact and accurate measurement and to effectively avoid loosening caused by vibration. The product adopts two methods for fixing the base and installing the busbar to adapt to various structures of cabinets and site conditions, achieving unprecedented installation flexibility.
2. Excellent performance and technical specifications
The DP series is structurally innovative, while its core performance indicators are at the forefront of the industry, guaranteeing that the monitoring data is highly accurate and stable in the long term.
2.1 Precise measurement and wide adaptability
This series of products covers the range from 5A to 5000A, and the accuracy class can be 0.2, 0.5, and 1.0, which can satisfy the different needs from general metering to high-precision protection. It employs high-quality silicon steel sheet iron core and a highly stable winding process to maintain excellent linearity and low phase angle error within the range of working temperatures from -25 °C to +75 °C and humidity ≤ 85%, ensuring reliability under a wide range of load conditions.
2.2 Powerful Load Capacity and Reliability
It can be seen from the technical parameter table that different sub-models of DP, like DP-23, DP-58, DP-816, and so on, provide different rated current ratios and load capacities. This kind of open close current transformer design does not sacrifice electrical performance but makes a breakthrough in small size and large capacity based on optimization of the internal structure. Various kinds of measuring instruments and protective relays can be directly connected to it, and it also has better system integration.
3. The wide range of application scenarios and value realization
The design intention of the DP series open close current transformer is to solve practical application problems, and its value will be fully demonstrated in a variety of scenarios.
3.1 Industrial Automation and Energy Efficiency Management
During the monitoring of the motor, air compressor, frequency converter, and other equipment, the DP series is able to implement real-time current collection and provide key data in energy efficiency analysis and predictive maintenance. In particular, its opening and closing feature is especially suitable for the retrofitting and upgrading of production lines and no work stoppages are required for the installation of the monitoring points.
3.2 Distribution system and energy internet
The DP series is used for accurate measurement of current, power, and electrical energy for distribution cabinets, smart grids, photovoltaic inverter systems, and charging stations. Core sensing component for achieving distribution automation, demand side response, and energy metering, it is easy to install and greatly reduces the cost and time of new construction and renovation.
3.3 Building Intelligence and Security Protection
It will provide real-time monitoring for HVAC, lighting systems, data center power supply circuits, etc., and integrate with a building automation system. Meanwhile, it provides the signal source for relay protection and fault arc detection devices, ensuring electrical safety.
4. Conclusion
