A transformer and a transformer machining process, including two coil units arranged side-by-side, each unit including an inner coil and an outer coil sleeved on the outside of the inner coil, an outer coil semi-conductive layer being wrapped on the outside of the outer coil and an inner coil semi-conductive layer being wrapped on the outside of the inner coil, and an insulating layer being integrally cast with the coil unit. In the transformer provided by the present application, the arrangement of the outer coil semi-conductive layer and the inner coil semi-conductive layer can effectively improve the problem of excessive local field strength caused by an irregular coil structure and solve the issue of wire package cracking caused by steel material generating heat in a pouring body; thus, the transformer has improved safety.

A fuse mounting structure and a batter system are provided according to the present application, the fuse mounting structure is used for mounting a fuse to a battery box, and includes a drawer and a fuse base; where the fuse base is mounted in the battery box, and the drawer is used for mounting the fuse; the drawer is provided with a guide device in a sliding fit with the fuse base, so as to guide the drawer to be inserted into the fuse base. According to the fuse mounting structure, the guide device is arranged on the drawer, the guide device guides the drawer with fuse when the drawer enters the fuse base, there is no need to align the plug-in holes, which realizes blind insertion of fuses and reduces the workload of fuse insertion.
