Problems solved by technology
[0002] Most of the existing integrated automatic transfer switch appliances use electromagnets, linear motors or manual direct rotation to connect the main power supply side or the backup power supply side to drive the contact system to the closed position. Because the force generated by the electromagnet is limited by the volume, At the same time, direct manual operation is also difficult to generate a large operating force, which limits the capacity of the transfer switch.
If the previous electromagnet, linear motor or manual operating system is used in the large-capacity integrated automatic transfer switch, it will require a large volume and poor reliability.

Embodiment Construction
[0022] Referring to FIGS. 1 to 9 , FIGS. 1 to 9 disclose structural diagrams of a transfer switch device according to an embodiment of the present invention, including an overall structural diagram and an exploded structural diagram of various components therein.
[0023] As shown in the figure, the transfer switch device 100 is installed between the normal side power supply and the standby side power supply. The transfer switch device 100 includes a front base 102 and a rear base 103 , a contact system and an operating system 101 .
[0024] The combination of the front base 102 and the rear base 103 defines a space, and in one embodiment, the front base 102 and the rear base 103 are insulating bases. The combined front base 102 and rear base 103 are divided into four phases, and the contact system is installed in the space formed by the front base 102 and the rear base 103 . The contact system connects and disconnects the circuit, and the contact system includes a moving cont...

The invention discloses a change-over switch appliance which is mounted between a common side power supply and a standby side power supply and comprises a front base, a back base, a contact system and an operation system. The front base and the back base are combined to define a space. The contact system is mounted in the space for connecting or disconnecting circuits, and comprises a moving contact and a static contact; the moving contact comprises three working stations, namely, a common side, a middle station and a standby side. The operation system is mounted on the front base, and is an energy storing mechanism for realizing the separating-combining operation; the operation mechanism is connected to the moving contact through a connecting rod; the operation system comprises a common side operation mechanism and a standby side operation mechanism connected by a gear set; the common side operation mechanism and the standby side operation mechanism are respectively mounted on the upper and lower sides of the front base, and are connected to a shank or a motor through common shafts. The shank or the motor finishes the energy storing operation to the common side operation mechanism and the standby side operation mechanism within one revolution.
Description
technical field [0001] The invention relates to the field of low-voltage electrical appliances, and more specifically, relates to a switch electrical appliance with automatic conversion capability. Background technique [0002] Most of the existing integrated automatic transfer switch appliances use electromagnets, linear motors or manual direct rotation to connect the main power supply side or the backup power supply side to drive the contact system to the closed position. Because the force generated by the electromagnet is limited by the volume, At the same time, direct manual operation is also difficult to generate a large operating force, so that the capacity of the changeover switch is limited. If the previous electromagnet, linear motor or manually operated operating system is used in the large-capacity integrated automatic transfer switch, it will require a large volume and poor reliability. Contents of the invention [0003] The present invention aims to propose a...
