Manual and electric modular three-station mechanism and interlocking device

Abstract

The invention belongs to the high voltage switchgear technical field and relates to a manual and electric modular three-station mechanism and an interlocking device. According to the manual and electric modular three-station mechanism and the interlocking device, a crank, an operation panel assembly, a driving mechanism, a pin, a connecting sleeve and a transmission mechanism are adopted; the crank is detachably connected with the operation panel assembly and the driving mechanism; the operation panel assembly is connected with the driving mechanism; and the driving mechanism is connected with the transmission mechanism through the pin and the connecting sleeve. The manual and electric modular three-station mechanism and interlocking device of the invention can be either operated electrically or manually to complete grounding, isolating/grounding switching on and isolating switching on; the driving mechanism and the transmission mechanism form an angular power transmission relationship; and the interlocking device limits the uniqueness of the operation of the mechanism, so that the misoperation and violent damage of the mechanism can be effectively prevented, and the reliability and modularity of the mechanism can be improved. The manual and electric modular three-station mechanism is convenient to maintain. With the manual and electric modular three-station mechanism and interlocking device adopted, a new option can be provided for the automation of a power distribution network.

Description

technical field [0001] The invention belongs to the technical field of high-voltage switchgear, and in particular relates to a manual and electric modularized three-station mechanism and an interlock. Background technique [0002] The three-position switch is an electrical device used to switch the on, off, and ground states. The three-position switch can generally be divided into knife switch type, direct-action type and other methods according to its contact movement mode. The direct-action three-position switch is generally matched with a manual operation mechanism that changes from rotation to direct action due to its own characteristics. A direct-acting three-station operating mechanism: First of all, whether it is single-axis operation or double-axis operation, multi-turn operation is used to complete the station switching, and the number of operation turns of each manufacturer is not uniform. When the cabinet is in use, it is easy for the operator to misuse, time-con...

The three-position switch can generally be divided into knife switch type, direct-action type and other methods according to its contact movement mode. The direct-action three-position switch is generally matched with a manual operation mechanism that changes from rotation to direct action due to its own characteristics. A direct-acting three-station operating mechanism: First of all, whether it is single-axis operation or double-axis operation, multi-turn operation is used to complete the station switching, and the number of operation turns of each manufacturer is not uniform. When the cabinet is in use, it is easy for the operator to misuse, time-consuming and laborious, and the operation efficiency is low; secondly, the State Grid has put forward intelligent requirements for the switch, and the current manual operation method obviously cannot meet the requirements; thirdly, due to the error of the mechanical in-position indication and the operator According to the operating habits, the operator cannot judge whether the switch is in place accurately through the operating handle or the indicator plate, especially when the operator operates the mechanism to the grounding position / isolation position, the grounding position / isolation position is caused by excessive operating force. The switching force of the position is large, stuck, stuck, and even the operator's violent operation directly damages the mechanism; finally, due to the above poor design, the interlock operation is not in place or the interlock design is complicated
