Problems solved by technology

If the operator does not wear insulating gloves or the insulation level of the insulating gloves is not enough, unfortunately the isolating switch leaks at this time, and an electric shock accident will occur when it is opened or locked.
Such electric shock accidents often occur in the rail transit catenary, causing great losses to society and enterprises
[0003]The above-mentioned traditional manual operation mechanisms such as CS11 and CS14 have defects such as cumbersome opening and locking; easy to rust; unreliable, etc.

Abstract

The invention provides the manual operating mechanism of the isolating switch, which is safe and standard, is simple to operate, is reliable and durable, and greatly reduces electric shock accidents generated when the manual operating mechanism is used for opening and closing.

Description

technical field [0001] The invention relates to an electrical isolation switch, in particular to the technical field of manual operating mechanisms of the isolation switch. Background technique [0002] The manual operating mechanism for power distribution isolating switch is a common power equipment, especially in the field of rail transit catenary. Usually the isolation switch is installed on the upper part of the power tower or pole, and the manual operating mechanism is installed on the lower part of the tower or pole; the manual operating mechanism handle is covered by an insulating rod and rotated 90°, the manual operating mechanism handle drives the output shaft to rotate, and the output shaft drives A long transmission tube, the transmission tube drives the isolation switch to open and close. A padlock is installed on the manual operating mechanism for unrelated personnel to misuse the manual operating mechanism. Unlock before opening and closing, and lock after op...
