[0002] The high-voltage switchgear promoted in the power system is a fully enclosed central cabinet. When the central cabinet receives and distributes network power, it mainly relies on the operation of the handcart switch in the cabinet. The handcart switch is shaken into the cabinet to contact the dynamic and static contacts. At this time, the main circuit is connected and the switch is in the working position. It can be closed and opened through the control circuit. If the insertion stroke of the dynamic and static contacts is not enough, it will cause poor contact, which is a hidden danger to the safe operation of the switch cabinet.

Abstract
The invention discloses a measurer for the stroke of moving and fixed contacts of a middle-placed switch cabinet handcart switch. The measurer comprises upper and lower ring-shaped bases which are opposite to each other, wherein flexible chains are connected between the two ring-shaped bases; each ring-shaped base comprises flexible chain seats arranged at intervals; an adjusting plate is movably connected between two adjacent flexible chain seats; and the flexible chains are positioned between two flexible chain seats corresponding to the two bases. The measurer has the advantages of simple structure and capacity of measuring the stroke of the moving and fixed contacts of the middle-placed switch cabinet handcart switch.
Description
technical field [0001] The invention relates to the field of central cabinets, in particular to a stroke measuring device for moving and static contacts of a handcart switch. Background technique [0002] The high-voltage switchgear promoted in the power system is a fully enclosed central cabinet. When the central cabinet receives and distributes network power, it mainly relies on the operation of the handcart switch in the cabinet. The handcart switch is shaken into the cabinet to contact the dynamic and static contacts. At this time, the main circuit is connected and the switch is in the working position. It can be closed and opened through the control circuit. If the insertion stroke of the dynamic and static contacts is not enough, it will cause poor contact, which is a hidden danger to the safe operation of the switch cabinet. Contents of the invention [0003] The object of the present invention is to provide a measuring device with simple structure, which can measur...
