Our Outdoor SF6 Circuit Breaker for Wind Farm Collector Substations and Grid Connection is engineered to meet the critical protection and switching needs of wind power infrastructure. This product ensures safe and efficient power collection from multiple turbines and secure interconnection to the main grid, offering wind farm operators a durable and high-performance component essential for system integrity and operational continuity.

The core value of this circuit breaker lies in its ability to provide superior electrical isolation and fault protection in harsh outdoor environments. Designed specifically for the unique challenges of wind farms—including remote locations, variable weather conditions, and the need for minimal maintenance—it serves as a vital link between the renewable generation source and the utility network.

Key Features & Technical Specifications:

Optimized for Wind Farm Applications: Specifically designed for the electrical characteristics and layout of wind farm collector substations, handling the aggregated power from turbine arrays.
SF6 Gas Insulation: Utilizes sulfur hexafluoride (SF6) gas as the insulation and arc-quenching medium, providing excellent dielectric strength and reliable performance in compact outdoor designs.
High Reliability in Outdoor Conditions: The housing and internal components are built to withstand environmental stresses such as UV exposure, temperature extremes, moisture, and corrosion.
Flexible Configuration Options: Available in various rated voltages and currents to match specific project requirements. Breaking capacity ratings are designed to protect the collector system and grid connection point effectively.
Multiple Control Options: Can be equipped with manual (spring-operated) or automated (motor-operated) mechanisms. Supports local control as well as integration into SCADA systems for remote monitoring and operation.
Safe and Secure Operation: Features clear status indication, secure locking systems, and designed with operator safety in mind.

Technical Parameters Table:

Parameter	Typical Range / Specification	Notes
Rated Voltage (Ur)	24kV, 36kV	Common voltages for wind farm collection; other voltages available upon request.
Rated Current (Ir)	630A, 1250A, 2000A, 2500A	Scalable to match the total capacity of the turbine array.
Rated Short-Circuit Breaking Current (Isc)	25kA, 31.5kA, 40kA	Provides high-level protection for the substation and grid connection.
Insulation Medium	SF6 Gas	Offers stable insulation and effective arc extinction.
Operating Mechanism	Spring-operated, Motor-operated	Choice based on automation needs and budget.
Installation Type	Pole-mounted, Ground-mounted (pad-mounted)	Adaptable to different site layouts and foundations.
Ambient Temperature Range	-40°C to +55°C	Suitable for operation in most climatic zones.

Frequently Asked Questions (FAQ):

Q: Why is an SF6 circuit breaker preferred for outdoor wind farm applications?
A: SF6 gas offers excellent insulating properties and arc-quenching capability in a compact format. This allows for a robust, sealed outdoor unit that requires less maintenance and performs reliably across a wide temperature range, which is ideal for remote wind farm sites.
Q: Can this circuit breaker be integrated with existing wind farm SCADA or control systems?
A: Yes. It can be supplied with motor-operated mechanisms and standard control interfaces (often auxiliary contacts and voltage requirements for motor control) that allow for integration into supervisory control and data acquisition (SCADA) systems for remote operation and status monitoring.
Q: What are the typical installation methods for this outdoor breaker?
A: It is designed for either pole-mounted installation on a dedicated structure or ground-mounted (pad-mounted) on a concrete foundation. The specific mounting details and accessories can be provided based on your site layout.
Q: How does the rated current selection relate to my wind farm's capacity?
A: The rated current should be selected based on the total maximum current expected from the collective output of all turbines connected to the collector substation. We offer a range from 630A to 2500A to accommodate different farm sizes.
Q: Is special training required for operating or maintaining this SF6 breaker?
A: General training on high-voltage switchgear operation and safety is recommended. For specific maintenance procedures related to the sealed SF6 system, guidelines are provided. The design aims for user-friendly operation with clear indicators.
Q: What is the expected service life or maintenance interval for this product?
A: Due to the sealed SF6 system and outdoor-rated construction, these breakers are designed for long service life with minimal maintenance. Typical maintenance intervals for mechanical checks and inspections are in the range of several years, depending on operating cycles.
Q: Can you provide customized voltage or breaking capacity ratings not listed in the standard range?
A: As a manufacturer, we have the capability to customize key parameters like rated voltage, current, and breaking capacity to meet specific project requirements. Please consult with our technical team during the inquiry stage.
Q: What support do you offer for shipping and delivery to international projects?
A: We have experience exporting to global markets and ship from major Chinese ports (Shanghai, Tianjin, Guangzhou, Ningbo). We can arrange packaging, documentation, and logistics suitable for international transport to your site.
