Carbon fiber high-voltage switch cabinet

Abstract

The invention discloses a carbon fiber high-voltage switch cabinet, and belongs to the technical field of switch cabinets. The carbon fiber high-voltage switch cabinet comprises a switch cabinet shell, a switch cabinet framework, a disconnecting link, a vacuum switch and a current transformer. The carbon fiber high-voltage switch cabinet is characterized by further comprising an electronic device and a switch cabinet front / rear door linkage device, wherein the electronic device consists of a motor and a two-stage speed reducer consisting of two groups of worm gears and worms; a telescopic plate and linkage plates are respectively fixed on a front door and a rear door through two fixed moving shafts; the telescopic plate is connected with the linkage plates through hinge pins; four linkage plates are connected through hinge pins and are fixed on the framework through rotating shafts; the main shaft of the motor is connected with a worm I; the worm I is used for driving a worm gear I; the worm gear I is connected with a worm II; the worm II is connected with a coupling; a clutch is arranged between the worm II and the main shaft of a divide-shut brake.

Description

technical field [0001] The invention relates to a carbon fiber high-voltage switch cabinet and belongs to the technical field of switch cabinets. Background technique [0002] The carbon fiber high-voltage switchgear used in the past has the following disadvantages: [0003] ① The instrument room is set in the switch cabinet, and the activity space in the cabinet is small, so it is inconvenient to repair and maintain. [0004] ②The manual operation mechanism is adopted, the operation procedure is relatively complicated, and it is easy to cause misoperation. [0005] ③ There is no spring acceleration device on the knife switch, and the opening and closing speed of the knife switch is relatively slow. [0006] ④ There is no linkage device between the front and rear doors of the switch cabinet, and it is easy to cause accidents of electric shock and casualties if people enter the live compartment by mistake. [0007] ⑤ The anti-misoperation program lock used in the switchgea...
