10KV 24KV Photovoltaic Grid Connected Cabinet 630A MV HV Power Distribution Cabinet

The ASHAN Series Photovoltaic Grid-Connected Cabinet is a specialized medium-voltage switchgear solution designed specifically for the renewable energy sector. Utilizing the industry-standard KYN28-12/24 metal-clad framework, this cabinet serves as the critical safety bridge between the PV inverter stations and the public utility grid.

Operating within the 10kV to 24kV range, this switchgear manages the synchronization, metering, and protection of solar-generated power. It is equipped with advanced protection relays to monitor frequency, voltage fluctuations, and anti-islanding protocols, ensuring that your solar plant complies with stringent grid-connection codes while protecting the system from surges and back-feeds.

• Specialized PV Grid Protection: Integrated with smart protection relays for Under-Voltage, Over-Voltage, and Anti-Islanding protection, essential for securing utility approval for grid-tied solar projects.

• KYN28 Withdrawable Architecture: Features a center-mounted vacuum circuit breaker (VCB) on a withdrawable truck. This allows for rapid isolation and maintenance without de-energizing the main busbar.

• High-Precision Revenue Metering: Designed with dedicated compartments for high-accuracy Current Transformers (CT) and Voltage Transformers (VT) required for utility billing and energy export monitoring.

• Arc-Proof Metal-Clad Design: The cabinet is divided into four grounded compartments (Busbar, Breaker, Cable, and Low Voltage) to localize faults and ensure maximum personnel safety at high-voltages.

• Al-Zn Coated Steel Enclosure: Constructed from high-precision, CNC-machined aluminum-zinc coated steel, providing a 25+ year service life even in the high-UV and dusty environments common to solar farms.

1. Utility-Scale Solar Farms: The primary medium-voltage interface between centralized or string inverters and the HV substation.

2. Commercial & Industrial (C&I) Solar: Managing grid-connection for large-scale rooftop arrays on factories and shopping malls.

3. Battery Energy Storage (BESS): Serving as the switchgear for grid-tied energy storage containers.

4. Distributed Generation: Grid-connected hubs for microgrids and community solar projects.

• Utility Approval Ready: We customize the protection logic and metering requirements to meet the specific "Grid Code" of your local utility provider.

• Superior Interlocking Safety: Features the standard KYN28 "Five-Prevention" mechanical interlocks to prevent operator error during manual switching operations.

• Environmentally Rugged: Optional internal heaters and ventilation systems are available to handle the temperature extremes and humidity often found at remote solar project sites.

• Smart Monitoring Integration: Fully compatible with SCADA systems via RS485, Modbus, or Fiber Optic communications for real-time remote monitoring of plant output.

Q: Can this cabinet handle the 24kV rating for international grids?

A: Yes. We offer a specialized 24kV KYN28 chassis that utilizes enhanced insulation distances and superior dielectric barriers to safely operate at 24kV while maintaining a compact footprint.

Q: Does it include the Anti-Islanding protection?

A: Absolutely. This is a core feature of our PV Grid-Connected series. We use high-end digital protection relays that monitor the grid status and disconnect the solar plant within milliseconds of a grid failure.

Q: What vacuum circuit breakers do you use?

A: We typically use high-performance VS1 or ABB VD4 vacuum circuit breakers, depending on project specifications and required switching cycles.

KYN28A-12 Armored removable AC metal closed switchgear

This equipment is indoor metal armored with drawable switchgear (hereinafter referred to as switchgear). It is a complete power distribution device of 3.6-12KV three-phase AC 50Hz single bus and single bus segmented system, mainly used in power plants. Small AND medium-sized generators, power distribution of industrial and mining enterprises, as well as the secondary substation of the electric system, power receiving, power transmission and large high voltage motor starting. For the purpose of control protection and monitoring, the switch equipment meets IEC298, GB3906 and other standard requirements. It has the interlocking function of preventing the push-pull circuit breaker hand car with load, preventing the mistake of splitting and closing the circuit breaker, preventing the grounding switch from closing the circuit breaker when the grounding switch is in the closed position, preventing it from entering the live chamber, and preventing the mistake of closing the grounding switch when the power
is live. It can be equipped with VS1 vacuum circuit breaker, and it is a kind of performance distribution device.
