Technical Field
The utility model belongs to the technical field of low-voltage electrical appliances, and particularly relates to a manual operation structure of a switch device operation system, which is particularly suitable for a dual-power automatic transfer switch.
Background
The dual-power automatic transfer switch is widely applied to modern power transmission and distribution line systems, especially in the occasions of hospitals, intelligent buildings, data centers, power plants, banks, important infrastructures and the like needing to keep power supply continuity. In the working process of the dual-power automatic transfer switch, the reliability of the transfer and the stability of the operation are directly related to the continuous power supply output state of the power transmission and distribution line; the dual-power automatic transfer switch comprises two types, namely a two-position automatic transfer switch and a three-position automatic transfer switch; the two-position automatic change-over switch is switched between two states of a common side power supply switching-on state (simultaneous standby side power supply switching-off state) and a standby side power supply switching-on state (simultaneous common side power supply switching-off state), so that continuous, stable and reliable electric energy output of a power transmission and distribution line is realized. The three-position automatic change-over switch can realize the working state of the two-position automatic change-over switch, and can also realize that the common side power supply and the standby side power supply are in a switching-off state (namely a double-split state) simultaneously, and lock the switching-off state.
The operating system is used as a core part in the dual-power automatic transfer switch, provides kinetic energy for position conversion of the automatic transfer switch, and is linked with a contact system of the automatic transfer switch through an output part to perform switching-on position state conversion between a common side power supply and a standby side power supply; the operating system of the automatic change-over switch in the two positions has two states, which respectively correspond to the common side power supply switch-on position and the standby side power supply switch-on position. The operating system of the three-position automatic change-over switch has three states, which respectively correspond to a common side power supply switch-on position, a standby side power supply switch-on position and a double-branch position.
