The invention provides an armored type metal sealed switch cabinet with a transformer cabin and a fuse handcart. An instrument cabin, a fuse handcart cabin, the transformer cabin and a main bus cabin inside the metal armored switch equipment cabinet of the switch cabinet are divided by metal plates; the fuse handcart is mounted in the fuse handcart cabin; a transformer is mounted in the transformer cabin; electric arc air flow pressure release channels are arranged in the fuse handcart cabin, the transformer cabin and the main bus cabin; the channel openings are formed in the top of the cabinet; the static contact of the line inlet end of the fuse handcart is connected with the first main bus and the second main bus of the main bus cabin through a first connecting copper bar and a second connecting copper bar; the line outlet end of the fuse handcart passes through a post insulator and is connected with the transformer through a third connecting copper bar. The switch cabinet has the benefits that the switch cabin is good in corrosion resistance, is safe and high in integration level as high voltage and low control voltage are isolated by steel plates, is capable of achieving the functions of incorrect operation prevention and interlocking, and is simple, rapid and convenient to install.
