IP3X To IP67 Protectionclass High Voltage Switchgears With Breakingcapacity Up To 50kA And Remote Control For Industrial Applications

Product Description:

Technical Parameters:

The rated voltage options available are 12kV, 24kV, and 36kV, which correspond respectively to the 10kV, 20kV, and 35kV distribution network systems. This range ensures compatibility with different network requirements.

Frequency ratings include both 50Hz and 60Hz, making the equipment suitable for use in global power grids where these are the most common frequencies.

The rated current of the main circuit can be either 630A or 1250A. The 630A rating is the standard configuration, designed for continuous long-term operation.

Regarding short-time withstand current, the device supports values of 16kA, 20kA, 25kA, and 31.5kA, with a withstand duration of 3 seconds as per national standards. The peak withstand current ratings are set at 40kA, 50kA, 63kA, and 80kA, which equate to 2.5 times the rated short-time withstand current.

The rated insulation level includes a power frequency withstand voltage of 42kV for the 12kV class equipment, along with a lightning impulse withstand voltage of 75kV for the same class. These values progressively increase with the voltage class.

Protection classification is specified as IP4X for the cabinet shell, providing dust protection, and IP67 for the switch components, making them suitable for outdoor environments where immersion might occur.

The earthing switch is rated for a short-time current of 2000A, ensuring safe grounding during short-circuit faults.

Two types of operating mechanisms are available: manual operation and electric operation. The electric option includes support for remote control, with an optional energy storage motor.

Fuse configurations are compatible with XRNT-type high breaking capacity fuses, with a rated current range from 6.3A to 400A, primarily intended for transformer protection applications.

Environmental conditions for operation include a temperature range from -25°C to +40°C, altitude up to 1000 meters (with customization possible for higher altitudes), and humidity not exceeding 95% without condensation. Specialized models can be customized for high-altitude or anti-corrosive environments.

The cabinet material options consist of cold-rolled steel plates with plastic spraying, or stainless steel grades 304 and 316. Stainless steel is especially suitable for environments with coastal or chemical corrosion.

Primary circuit schemes can be customized according to the distribution network topology, including configurations such as 2-in-2-out, 3-in-3-out, and terminal types.

Secondary control features are optional and include intelligent measurement and control units, temperature and humidity controllers, as well as fault indicators. These features support integration with SCADA systems for remote monitoring and management.
