Manual operating mechanism of jack box

Abstract

The invention discloses a manual operating mechanism of a jack box, which consists of an operating handle, a direction board, a rotating shaft, a fixed sleeve, a poke rod assembly, a rocking arm bracket, a rocking plate base, a shaft sleeve and a plastic shell switch. The fixed sleeve is fixed on the shell of the jack box; the rotating shaft is sleeved inside the fixed sleeve after passing through the operating handle and a small hole at the end part of the direction board and can rotate inside the fixed sleeve; the poke rod assembly is fixed at the internal end part of the rotating shaft; a cylindrical bulge on the poke rod assembly is inserted into a wasted hole of a rocking arm bracket arm brace, the arm braces at two ends of the rocking arm bracket are provided with connecting holes; the rocking arm bracket is fixed by the shaft sleeve through the connecting holes in the rocking arm bracket arm brace and the rocking plate base arm brace, and the rocking arm bracket can be ensured to rotate around the shaft sleeve; a trough plate arranged in the rocking arm bracket locks a brake handle of the plastic shell switch, and the rocking plate base is fixed on the plastic shell switch by bolts.

Description

technical field [0001] The invention belongs to the field of low-voltage complete switchgear, and relates to a manual operation mechanism of a plug-in box in the power transmission and distribution industry. Background technique [0002] In the existing technology of power transmission and distribution facilities, the busway series products are in a diversified development trend, while the traditional plug-in box operating mechanism or no operating handle outside the box, the cover of the plug-in box needs to be opened every time the switch is operated, and the operator is extremely It is easy to touch the electrical lines inside the box, causing potential safety hazards; especially for the switch operation of the plug-in box for busway erected at high altitude, it is necessary to open and fix the cover of the plug-in box with one hand, and push the plastic case switch inside the box with the other hand. Another way is to install the operating rotary handle on the cover of t...

[0002] In the existing technology of power transmission and distribution facilities, the busway series products are in a diversified development trend, while the traditional plug-in box operating mechanism or no operating handle outside the box, the cover of the plug-in box needs to be opened every time the switch is operated, and the operator is extremely It is easy to touch the electrical lines in the box, causing potential safety hazards; especially for the switch operation of the plug-in box of the busway erected at high altitude, it is necessary to open and fix the cover of the plug-in box with one hand, and push the plastic case switch inside the box with the other hand

Another way is to install the operating rotary handle on the cover of the plug-in box. This method is only suitable for vertical installation of the bus duct and cannot meet the operation requirements of high-altitude erection and horizontal installation of the bus duct, and it is laborious to operate the rotary handle; After the on-off operation of the shell switch, the cover of the plug-in box needs to be closed and fixed reliably.
