Abstract

The invention discloses 12kV high-voltage switchgear. The switchgear comprises a cabinet (1), wherein a switch operating mechanism (4) located on the left side of a front door is arranged on the cabinet (1); a mechanical interlocking mechanism (20) is arranged on the back side of the switch operating mechanism (4); the mechanical interlocking mechanism (20) comprises a support (33), a crank arm (25), a connecting rod (24), an upper rotating arm (32), a lower rotating arm (22) and a locking plate (21); the locking plate (21) is parallel with a rotating shaft of an operation positioning handle (2) and can slide in a support (28); a hinge pin (3) is arranged on the locking plate (21); one end of the crank arm (25) is mounted on a circuit breaker drive shaft (26) of a vacuum circuit breaker (18). The 12kV high-voltage switchgear has the benefits as follows: the 12kV high-voltage switchgear is compact in structure, simple to operate and safe and reliable to use and has a complete mechanicalinterlocking function.

Description

technical field [0001] The invention relates to the technical field of electrical control equipment structure, in particular to a 12kV high-voltage switchgear. Background technique [0002] Fixed 12kV high-voltage switchgear is very popular in the market due to its advantages of simple structure, reliable connection of the primary conductive circuit, and low cost. However, for general fixed 12kV switchgear, due to factors such as component layout and switch operation mode, the overall size of the cabinet is designed to be relatively large. In many building power distribution projects, 12kV switchgear is mostly installed in the basement. Due to the limitation of underground space, the dimensions of the switchgear in the power distribution project need to be reduced as much as possible. Due to the large size of the existing fixed 12kV switchgear, it cannot be widely used in building power distribution projects. For fixed 12kV switchgear, the operation locking function of ci...
