Abstract

The utility model discloses an isolation switch operation mechanism. The isolation switch operation mechanism comprises a casing, wherein the casing is internally provided with a driving shaft and a transmission shaft which are mutually perpendicular to each other, an end head of the driving shaft is fixed with a driving gear, an end head of the transmission shaft is provided with a driven gear, the driving gear and the driven gear are engaged, the transmission shaft is connected with a connecting lever, the connecting lever is provided with spacing armatures, and the driving shaft is connected with a fixing bolt. According to the isolation switch operation mechanism, the driving gear is connected with a rocking handle through the fixing bolt, the driven gear is connected with and fixed with the connecting lever, the rocking handle is turned to drive the driving gear to rotate, the driving gear drives the driven gear to make the connecting lever to move up and down, closing/opening of the isolation switch are realized though a link rod, two spacing armatures on the connecting lever can realize closing and opening of the isolation switch.

Description

Isolator operating mechanism
Technical field
The utility model belongs to change over switch, is specifically related to a kind of isolator operating mechanism that isolating switch is operated.
Background technology
Isolating switch is used for each step voltage, connects or makes circuit or equipment and isolated from power as changing circuit, and its ability that do not stop can only operation again after with miscellaneous equipment, circuit being disconnected.The folding of isolating switch is controlled in isolating switch and operating mechanism coupling by operating mechanism.Yet general isolating switch complex structure, operation inconvenience.
The utility model content
The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provides that a kind of operation is light, isolator operating mechanism flexibly.
The technical solution of the utility model realizes in the following manner: a kind of isolator operating mechanism, comprise housing, be provided with orthogonal driving shaft and power transmission shaft in housing, the driving shaft termination is fixed with driving gear, the power transmission shaft termination is provided with driven gear, driving gear and driven gear engagement, and power transmission shaft is connected with connecting lever, connecting lever is provided with spacing armature, and driving shaft is connected with set bolt.
The number of teeth of described driving gear is less than the number of teeth of driven gear.
In the utility model, driving gear is connected with rocking handle by set bolt, driven gear is connected with connecting lever and fixes, rotating with rocking handle rotates driving gear, driving gear drives driven gear moves up and down connecting lever, make isolating switch deciliter by link rod, two spacing armature on connecting lever can be realized the folding of isolating switch.The utility model can make the fracture folding distance of isolating switch greater than 170, has light, the opening and closing in place of operation.This operating mechanism behaviour three-phase is good the same period, and the dynamic/static contact contact is good, and contact resistance is lower than the regulation requirement, and deciliter position signalling is correct, and every anti-misoperation locking is functional.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in drawings, a kind of isolator operating mechanism, comprise housing 7, be provided with orthogonal driving shaft 5 and power transmission shaft 3 in housing 7, driving shaft 5 terminations are fixed with driving gear 6, and power transmission shaft 3 terminations are provided with driven gear 1, driving gear 6 and driven gear 1 engagement, power transmission shaft 3 is connected with connecting lever 2, and connecting lever 2 is provided with spacing armature, and driving shaft 5 is connected with set bolt 4.The number of teeth of described driving gear 6 is less than the number of teeth of driven gear 1.Described driving gear 6 is pinions of 17 teeth, and driven gear 1 is the gear wheel of 30 teeth.
