Abstract
A handcart voltage transformer comprises a primary wiring terminal, a fuse, an iron core, a secondary wiring terminal, a primary coil, a secondary coil, a primary coil outgoing line, and a connecting contact terminal. The primary wiring terminal of the handcart voltage transformer is welded to one end of the fuse, the other end of the fuse is connected with the connecting contact terminal; the primary coil outgoing line is connected with the connecting contact terminal; the primary coil passes through the iron core for determining a corresponding feed-through winding number; the secondary coil is wound around the iron core uniformly and is connected with the secondary wiring terminal; and the voltage transformer is formed by pouring an epoxy resin material. The handcart cabinet voltage transformer has a simple structure and reasonable arrangement, contains the fuse in itself, and is especially applicable to the handcart cabinet.
