27kV Outdoor High-Voltage Vacuum Recloser

Description：

Pioneer in China’s recloser industry and the first source manufacturer dedicated to this field — this is our identity forged by decades of deep cultivation. Over the past decades, we have consolidated our development foundation through technological breakthroughs, led the industry direction by formulating standards, and successfully built a fully independent system covering core technology R&D, large-scale mass production and delivery.

The RCW series automatic circuit reclosers are designed for use in overhead distribution lines and distribution substations. They are compatible with power systems operating at 50/60Hz, covering voltage classes from 11kV to 38kV. With a rated current capacity of up to 1250A, these reclosers integrate multiple functions, including control, protection, measurement, communication, fault detection, and real - time monitoring of closing and opening operations. Composed of an integration terminal, current transformer, permanent magnetic actuator, and a dedicated recloser controller, the RCW series vacuum reclosers offer a comprehensive solution for power distribution network management.

Features:

• Flexible Current Ratings: Optional ratings within the rated current range to suit diverse application needs.

• Customizable Protection: A variety of optional relay protection and logic schemes for users to choose from, ensuring adaptability to different system requirements.

 What are the key points for the selection of outdoor vacuum reclosers？

• System Parameter Matching: Choose a recloser that matches the rated voltage, rated current, and short-circuit current levels of the power system. Ensure that the rated voltage of the recloser is equal to or higher than the system voltage, the rated current meets the requirements of the line load current, and the rated short-circuit breaking and making currents are greater than the maximum possible short-circuit current in the system.

• Reclosing Performance Requirements: Consider the specific requirements of the power system for the reclosing function, such as the number of reclosures, reclosing time intervals, and reclosing success rate. Based on different application scenarios and power supply reliability requirements, select a recloser with appropriate reclosing performance. For example, for critical power supply lines, a recloser with a higher number of reclosures and flexible reclosing time intervals may be required.

• Type of Operating Mechanism: Choose an appropriate operating mechanism based on actual needs. Spring-operated mechanisms are suitable for outdoor environments where high reliability is required and maintenance conditions are relatively poor. Permanent magnet-operated mechanisms are better suited for applications requiring high action speed and frequent operations.

• Environmental Adaptability: Given the harsh conditions of outdoor environments, consider the environmental adaptability of the recloser. This includes weather resistance, pollution resistance, and water and dustproof performance. Selecting a recloser with good environmental adaptability ensures stable performance during long-term outdoor operation.

• Brand and Quality: Choose well-known brands and high-quality recloser products. These products have strict quality control systems in design, manufacturing, and testing, ensuring the performance and reliability of the product. Additionally, good after-sales service is an important factor to consider when choosing a brand, as it ensures timely resolution of issues that may arise during equipment operation.
