Abstract: A mounting bracket includes a bracket body, a locking assembly and support foot. The bracket body is configured for component installation. The locking assembly is arranged on the bracket body, and the support foot is arranged on the bracket body. The support foot is slide along the up and down direction of the bracket body, and the locking assembly is configured to lock the support foot at a preset position. Through the above structure, the support foot is installed on the ground and used to support the bracket body, and the locking assembly locks the support foot at a preset position to correspondingly adjust the height of the bracket body from the ground, so as to adjust the suspension height of the components installed on the bracket body.

Abstract: Disclosed are a method and device for winding a foil coil of a stereoscopic wound iron core transformer. The device includes a rotating assembly, a driving device and a plurality of loading assemblies; the rotating assembly is provided with a through hole matched with an iron core post, the rotating assembly is provided with a gear plate and a track ring around the through hole, and the gear plate and the track ring are fixedly connected by a fixing block; the loading assembly includes a cylinder and a tension device, and the cylinder is movably connected with the rotating assembly; and a driving end of the driving device is connected with the gear plate.

Abstract: A winding die is disclosed, including: a gear baffle, where a middle portion of the gear baffle is provided with a first opening for placing an iron core post, and the gear baffle is provided with a first surface; and a cylinder, where the cylinder is arranged on the first surface of the gear baffle and connected with the gear baffle. The middle portion of the gear baffle is provided with the first opening for placing the iron core post, the gear baffle is fixedly connected with the cylinder, an external device is connected with a gear, and the cylinder on the gear baffle is driven to rotate around the iron core post by pulling the gear, so that a foil or an insulating material on the cylinder can be wound on the iron core post, finally realizing a foil winding.

Abstract: A winding cylinder of a stereoscopic wound iron core transformer is disclosed, including an outer cylinder, an inner cylinder and a tension assembly. The outer cylinder is movably connected with the inner cylinder through a bearing assembly, and the outer cylinder rotatable around an axis of the inner cylinder. The tension assembly includes a screw, a spring and a connecting assembly. The connecting assembly includes a fixing portion, a friction portion and a transmission portion, the friction portion and the transmission portion are both arranged around the inner cylinder, and the transmission portion is fixedly connected with the outer cylinder. A side face of the inner cylinder is provided with a through hole, and the fixing portion penetrates through the through hole and is fixedly connected with the friction portion.

Abstract: Embodiments of this application provide a method and an apparatus for determining virtual machine VM migration. The method includes: after a VM is migrated, sending a gratuitous ARP packet or a RARP packet to an in-migration VTEP device; obtaining, by the VTEP device, a MAC address of the VM, searching an ARP cache table based on the MAC address, and obtaining an IP address of the VM; and constructing an ARP unicast request packet by using the IP address as a destination IP address, and if the VTEP device receives an ARP response packet sent by the VM for the ARP unicast request packet, determining that the VM is migrated.
