Problems solved by technology

[0004] GIS equipment can be roughly divided into two parts, including the switch part and the drive part used to drive the switch part. In the prior art, hard shaft transmission is generally used to transmit the output power of the drive part to the switch part. Due to the limitation of hard shaft transmission The transmission distance and installation layout between the drive part and the switch part are greatly restricted, which leads to problems such as the overall volume of the GIS equipment is relatively large, the structure is complex, and the transmission efficiency is low.

Abstract

The invention discloses an intelligent operating mechanism for high-voltage distribution equipment. The intelligent operating mechanism comprises a driving part and a switching part, and is characterized in that the driving part is connected with the switching part by a flexible shaft, the driving part is provided with a driving motor, the switching part is provided with a transmission shaft, the driving motor rotates and drives the transmission shaft of the switching part to rotate via the flexible shaft, and the transmission shaft further drives the switching part to hand over the switching state. The intelligent operating mechanism has the advantages of small size, high efficiency and simple and reliable structure, reduces the connection of field control cables after being used, shortens the installation period, facilitates more reasonable spatial arrangement, and facilitates field operation and maintenance.

Description

technical field [0001] The invention relates to an intelligent operating mechanism of high-voltage power distribution equipment. Background technique [0002] Generally speaking, gas insulated switchgear (GIS: Gas Insulated Switchgear) is installed in indoor / outdoor power plants and substations. Under normal conditions, it can manually break the load current, safely cut off accidents or abnormal currents, and protect the power system and Switchgear for extra-high voltage power systems of power equipment. [0003] GIS equipment consists of circuit breakers, disconnectors, grounding switches, transformers, lightning arresters, busbars, connectors, and outlet terminals. Gas, so it is also called SF6 fully enclosed combined electrical appliance. [0004] GIS equipment can be roughly divided into two parts, including the switch part and the drive part used to drive the switch part. In the prior art, hard shaft transmission is generally used to transmit the output power of the d...
