Definitions

  • the present application relates to a manual operating mechanism for automatic transfer switching equipment and an automatic transfer switching equipment comprising such a manual operating mechanism.
  • ATSE Automatic transfer switching equipment
  • the operating mechanism of the ATSE is a key component for the reliability. It is important to provide an easy and reliable operating mechanism.
  • operating mechanism There are two types of operating mechanism, one is electrical operating mechanism and the other is manual operating mechanism. Generally, the electrical operating mechanism is used to control the transfer of the ATSE, but in the case that the electrical operating mechanism is failed or needs repair, the manual operating mechanism is used to control the transfer of the ATSE.
  • manual operating mechanism There are two types of manual operating mechanism, one is manpower manual operating mechanism and non-manpower manual operating mechanism. Current manual operating mechanism is manpower manual operating mechanism, which requires users to disconnect the power supply or the load when operating, otherwise a serious safety problem may be occurred since the electric arc generated between the mobile contact and the fixed contact is uncontrollable, which is undesirable for the users.

  • the teeth of the handle gear are only arranged on a portion of the circumference of the handle gear such that the handle gear is not engaged with the second energy-storing gear when the handle gear is engaged with the first energy-storing gear and the handle gear is not engaged with the first energy-storing gear when the handle gear is engaged with the second energy-storing gear.

Then, the first driving gear 5 rotates in counter-clockwise direction to engage with the central wheel 9, causing the central wheel rotates in clockwise direction and the main shaft of the ATSE rotates correspondingly to switch to the first power supply ON position, as shown in Fig. 4 .
  • the handle is at the second position and the ATSE is at the first power supply ON position.
  • the handle gear 2 is also rotated in clockwise direction.
  • the handle gear will engage with the first energy-storing gear 3 during the rotation in clockwise direction such that the first energy-storing gear rotates in counter-clockwise direction, and the first elastic element 7 which is mounted on the first energy-storing gear at one end deforms and stores energy.
  • the first driving gear 5 remains stationary by a second stopper mounted on the frame. The second stopper prevents the first driving gear from rotating in counter-clockwise direction upon the action of the first elastic element 7.

  • the handle gear 2 When the handle 1 is rotated in clockwise direction, the handle gear 2 is also rotated in clockwise direction.
  • the handle gear will engage with the second energy-storing gear 4 during the rotation in clockwise direction such that the second energy-storing gear rotates in counter-clockwise direction and the second elastic element 8 which is mounted on the second energy-storing gear at one end deforms and stores energy.
  • the second driving gear 6 remains stationary by a third stopper mounted on the frame.

  • a manual operating mechanism comprising a handle gear, energy-storing gears, driving gears and a central wheel is described above. Due to the manual operating mechanism of the present application, during the switching of the ATSE, the rotating speed of the mobile contact is irrelevant to the switching speed of the ATSE and the electric arc generated between the mobile contact and the fixed contact is controllable within an allowable range, and thereby it is not necessary to disconnect the power supply or the load.
