DUAL POWER TRANSFER SWITCH - A simplified explanation of the abstract
This abstract first appeared for US patent application 18745491 titled 'DUAL POWER TRANSFER SWITCH
Simplified Explanation:
This patent application describes a dual power transfer switch with a contact system that can connect two power sources to a load, as well as disconnect from the load. The switch includes a locking device to keep the contact system in the open position when needed.
- The contact system can move between a first closed position connecting the load to the first power source, a second closed position connecting the load to the second power source, and an open position disconnecting from the load.
- A locking device, including a locking link and a first actuator, is used to keep the contact system at the open position.
- The switch also includes a contact main shaft interlock device for additional functionality.
Key Features and Innovation:
- Contact system can switch between two power sources and disconnect from the load.
- Locking device ensures the contact system stays in the open position when required.
- Interlock device provides further control and functionality to the switch.
Potential Applications:
The dual power transfer switch can be used in various electrical systems where a seamless transfer between power sources is necessary, such as backup power systems, industrial machinery, and critical infrastructure.
Problems Solved:
This technology solves the problem of efficiently transferring power between two sources while ensuring a secure disconnection from the load when needed.
Benefits:
- Reliable and efficient power transfer between two sources.
- Secure disconnection from the load for maintenance or safety purposes.
- Enhanced control and functionality with the interlock device.
Commercial Applications:
The dual power transfer switch can be utilized in industries such as telecommunications, data centers, manufacturing, and healthcare where uninterrupted power supply is crucial for operations.
Prior Art:

Original Abstract Submitted
A dual power transfer switch includes a contact system, which has a contact main shaft rotatably arranged to move contact assemblies. The contact main shaft has a first closed position, a second closed position, and an open position. At the first closed position, the contact assemblies connect a first power source to a load. At the second closed position, the contact assemblies connect a second power source to the load. At the open position, the contact assemblies disconnects from the load. The dual power transfer switch also includes a contact main shaft locking device configured to keep the contact main shaft at the open position. The contact main shaft locking device includes a locking link and a first actuator. The dual power transfer switch includes a contact main shaft interlock device.
