Abstract
A transfer apparatus for a dual-power transfer switch and an associated dual-power transfer switch. The transfer switch includes a pair of pushing members adapted to be moved in opposite directions to control circuit breakers for the dual-power transfer switch in a mutually different manner; a transmission arm rotatably arranged between the pair of pushing members; a pair of pins arranged on radial ends of the transmission arm; and a pair of elastic reset components arranged on the pair of pushing members.
Claims20
A transfer apparatus for a dual-power transfer switch, comprising:
- a pair of pushing members adapted to be moved in opposite directions to control circuit breakers for the dual-power transfer switch in a mutually different manner, each of the pair of pushing members comprising a limiting slot;
- a transmission arm rotatably arranged between the pair of pushing members;
- a pair of pins arranged on radial ends of the transmission arm and each adapted to slide in the respective limiting slot with a rotation of the transmission arm to drive each respective pushing member of the pair of pushing members to move;
- and
- a pair of elastic reset components arranged on the pair of pushing members, wherein:
- a first elastic reset component of the pair of elastic reset components being arranged on a first pushing member of the pair of pushing members,
- a second elastic reset component of the pair of elastic reset components being arranged on a second pushing member of the pair of pushing members, and
- each of the first elastic reset component and the second elastic reset component is adapted to be pressed by each respective pin during sliding of each respective pin to ensure that each respective circuit breaker of the circuit breakers is reset or switched into an open state.
A method of assembling a transfer apparatus for a dual-power transfer switch assembly, comprising:
- providing a pair of pushing members adapted to be moved in opposite directions to control circuit breakers for the dual-power transfer switch in a mutually different manner, each of the pair of pushing members comprising a limiting slot;
- rotatably arranging a transmission arm between the pair of pushing members;
- arranging a pair of pins on radial ends of the transmission arm, the pair of pins each adapted to slide in the respective limiting slot with a rotation of the transmission arm to drive the respective pushing member to move;
- and
- arranging a pair of elastic reset components on the pair of pushing members, wherein:
- a first elastic reset component of the pair of elastic reset components being arranged on a first pushing member of the pair of pushing members,
- a second elastic reset component of the pair of elastic reset components being arranged on a second pushing member of the pair of pushing members, and
- each of the pair of elastic reset components adapted to be pressed by each respective pin during sliding of each respective pin to ensure that each respective circuit breaker of the circuit breakers be reset or switched into an open state with both of the circuit breakers being in the open state.
