Inflatable cabinet load switch fuse combination electrical mechanism

Abstract

The invention discloses a gas filled tank load switch fuse-combination unit mechanism. The gas filled tank load switch fuse-combination unit mechanism comprises a front plate, a rear plate, a closingspring, a motor and a switch-on and switch-off cam welding wire outlet mechanism. The front plate and the rear plate are separately arranged at the two ends of the mechanism, and the front plate and the rear plate are arranged in parallel. The gas filled tank load switch fuse-combination unit mechanism has the beneficial effects that a mechanism transmission mode is changed by the gas filled tankload switch fuse-combination unit mechanism, the mechanism transmission structure is optimized, good transmission property of the mechanism is ensured, and transmission operation is accurate and stable; a hexagonal shaft, a positioning shaft, a shaft III, a shaft IV and a shaft V are arranged between the front plate and the rear plate and perpendicularly penetrate through the front plate and the rear plate, and the strength and firmness of the integral mechanism during working are improved; shaft bodies are protectively isolated by shaft sleeves, friction and collision of the shaft bodies arerelieved, and the service lives of the shaft bodies are prolonged; and the electrical mechanism is high in sensitivity during working, is firm and durable, has good social benefit, and is suitable forbeing popularized and used.

Description

technical field [0001] The invention relates to an electrical mechanism, in particular to an inflatable cabinet load switch fuse combined electrical mechanism, belonging to the technical field of electrical mechanism applications. Background technique [0002] The inflatable cabinet is a new generation of switchgear. The main switch can use either a permanent magnet mechanism vacuum circuit breaker or a spring mechanism vacuum circuit breaker. The whole cabinet is combined with air insulation and sulfur hexafluoride gas compartment, which is compact and expandable. , suitable for distribution automation. The inflatable cabinet has the characteristics of compact structure, flexible operation, and reliable interlocking. It can provide satisfactory technical solutions for various applications (especially places with harsh environments) and different user requirements. The load switch fuse combined electrical mechanism is indispensable in the inflatable cabinet. The load switch...

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that the mechanical life test of the load switch outlet mechanism in the existing inflatable cabinet load switch fuse combination electrical mechanism generally cannot meet the requirements of the State Grid, and the service life, assembly efficiency and assembly pass rate are low. The mechanism transmission mode of the load switch fuse combination electrical mechanism of the inflatable cabinet is single, the transmission parts are not stable enough, and the working accuracy is low, and the existing load switch fuse combination electrical mechanism of the inflatable cabinet cannot be opened before closing or after closing. Energy storage cannot meet the test requirements, and when the mechanism stores energy, the components on the mechanism may be impacted due to excessive energy, and the service life of the components on the mechanism is low. The existing inflatable cabinet load switch fuse combination electrical mechanism has five defenses The interlocking performance is poor, the safety of use is poor, and the overall mechanism is not strong and durable, and the parts in the mechanism and the parts inside the inflatable cabinet are prone to collision and wear, and the working life of each part in the mechanism is low.
