This invention discloses a gas-insulated
metal-enclosed
switchgear bus tie cabinet. The cabinet consists of
circuit breaker cabinets and
instrument transformer cabinets arranged side by side. Each cabinet comprises a front cabinet, a
gas chamber, and a rear cabinet arranged sequentially from front to back, mounted on the
switchgear's base frame. The internal space of the gas chambers in both the
circuit breaker and
instrument transformer cabinets is divided into double chambers by horizontal partitions. The upper chamber of the
circuit breaker cabinet's
gas chamber is the circuit breaker cabinet
busbar chamber, and the lower chamber is the circuit breaker chamber. Similarly, the upper chamber of the
instrument transformer cabinet's
gas chamber is the instrument
transformer cabinet
busbar chamber, and the lower chamber is the instrument
transformer chamber. The circuit breaker and instrument
transformer chambers are interconnected, and the electrical components within are connected via
copper busbars, forming the lower chamber of the
bus tie cabinet. This invention meets relevant national standards, features a reasonable cabinet structure
layout, occupies a small area, is easy to select and combine, and facilitates
engineering design and
mass production. The two
switchgear units can form an organic whole with parallel-operating incoming line cabinets, outgoing line cabinets, and feeder cabinets, resulting in an aesthetically pleasing appearance.
