Abstract

The invention discloses a metal armored withdrawable high-voltage switch cabinet. An upper handcart chamber (2) is arranged at the front middle part of a cabinet body, a lower handcart chamber (3) is arranged at the front lower part of the cabinet body, a circuit breaker handcart (4) is arranged in the upper handcart chamber (2), a lower PT handcart (5) is arranged in the lower handcart chamber (3), a current transformer (6) and a grounding switch (7) are arranged in the cabinet body at the back side of the switch cabinet, and an arrester (8) and a zero-sequence current transformer (9) are installed in a cable room. By adopting the technical scheme, electric components, such as the circuit breaker handcart, the lower PT handcart, the current transformer, the grounding switch, the arrester, the zero-sequence current transformer and the like, are simultaneously arranged in a same switchgear, and therefore, through elaborate arrangement, the invention has the advantages of more reasonable layout, compactor structure optimizing the design scheme, reducing the construction investment and the earth occupancy and bringing considerable economic benefit.
