Intelligent rocking handle device of mobile switch cabinet

Abstract

The invention relates to an intelligent rocking handle device of a mobile switch cabinet. The device comprises a switch crank plug, a rocking handle and a connecting rod, a shell is arranged at the other end of the connecting rod, the rocking handle is detachably installed on the shell, a torque sensor is arranged between the connecting rod and the shell, a control chip connected with the torque sensor is arranged in the shell, and a data memory, a comparator and a display alarm device are connected to the control chip. The device has the advantages that the torque sensor is arranged between the connecting rod and the shell to acquire the acting force applied to the switch crank plug in real time, the acting force is compared with the comparator, and when the torque value measured by a certain operation is 30% higher than a set value, the situation that mechanical jamming or mechanical locking is not relieved is judged and determined, the control chip sends a warning instruction to thedisplay alarm device, the display alarm device sends an alarm prompt to an operator, and barbaric operation of the operator is prevented.

Description

technical field [0001] The invention relates to an intelligent rocker device for a mobile switch cabinet. Background technique [0002] As an important power equipment, the mobile switchgear needs to switch between the working position and the test position according to the requirements of power grid operation and inspection in the normal life cycle. At present, the conversion process of the mobile switchgear mainly depends on the cooperation of the crank handle / screw rod. The purely mechanical rocker / screw rod technology has the advantages of high reliability and low cost. The disadvantage is that the process of operating the screw rod with a common handle is not intuitive. , When there are abnormal conditions such as jamming and electrical mechanical locking, it cannot be found in time. Most of the existing trolley handles are handled through the experience of operators, which may cause damage to the mechanical components of the chassis. Contents of the invention [000...
