Product Description

ZN85-40.5 Circuit Breaker Hand Truck PT Trolley For KYN61 Switchgear 

The ZN85-40.5 PT Trolley is designed specifically for 1200mm width switchgear as a potential transformer (PT) trolley without an operating mechanism.
Unlike vacuum circuit breakers, which include mechanisms for switching and protection, this trolley is dedicated to holding and moving the PT and does not perform switching operations itself. Therefore, it lacks an integrated operating mechanism.

Primary Function:
It is used to house and maneuver potential transformers in high-voltage switchgear systems. Potential transformers are crucial for voltage measurement and system protection by providing scaled-down voltage readings to control systems.

Switchgear Compatibility:
Specifically designed to fit into 1200mm width switchgear like KYN61-40.5 or similar models, the PT trolley meets relevant standards such as IEC 62271 and GB/T 11022. These standards ensure that the trolley is safe, reliable, and suitable for high-voltage electrical applications.

Application in Power Systems:
PT trolleys are commonly used in power plants, substations, and industrial enterprises for voltage measurement, overload protection, and ensuring electrical safety during system maintenance. The handcart design allows for smooth, secure insertion and removal of PTs, ensuring the system operates efficiently without interrupting power.

Interlocking and Safety:
It features mechanisms to prevent misoperation, offering protection during maintenance or when PTs are being removed or inserted.

Technical Standards:
The trolley adheres to specifications like:
Rated voltage: 40.5 kV
Power frequency withstand voltage: 95 kV
Lightning impulse withstand voltage: 185 kV
Applicable environments: Temperature range of -40°C to +40°C, with a maximum altitude of 1000 meters
