Abstract
The utility model discloses a device capable of reducing the operating force of disconnecting switch, which comprises a speed reducer hand-operated input part of a disconnecting switch operating mechanism, and is characterized in that the speed reducer hand-operated input part is connected with an output shaft of a box type speed reducer, the box type speed reducer is provided with an input shaftwith a rocker jack, and at least a two-stage speed reducing gear mechanism is arranged between the input shaft and the output shaft.
Description
Technical field
The utility model relates to a kind of device of the alleviated operating physical force that is connected with isolating switch operating mechanism reducer arrangement.
Background technology
In recent years, fast development along with China's power industry, the power transmission and transformation system of big electric current (rated current 5000A), superhigh pressure (800KV-1000KV) becomes a new developing direction, and in this system used big capacity, superhigh pressure isolating switch because the increase of volume, the moment of torsion of this kind equipment of operation is significantly increased, cause manual operation power to increase, surpass the GB requirement of manual operation power value≤60N.
Summary of the invention
The purpose of this utility model provides a kind of device that alleviates isolator operation power.For reaching above purpose, the utility model takes following technical scheme to be achieved:
A kind of device that alleviates isolator operation power, comprise the hand input of isolating switch operating mechanism decelerator position, it is characterized in that, the hand input of this decelerator position is connected with the output shaft of a boxlike decelerator, this boxlike decelerator is provided with the power shaft of band joystick jack, is provided with double reduction gearing mechanism between this power shaft and the output shaft at least.
In the such scheme, described double reduction gearing mechanism comprises gear wheel, a pinion that connects firmly with power shaft that connects firmly with output shaft, between the big pinion by transition gear engagement.The no-load voltage ratio of pinion and transition gear is 1: 1; The no-load voltage ratio of gear wheel and transition gear is 2: 1.
The utility model has the advantages that, make the manual operation power of the big capacity of operation, superhigh pressure isolating switch reduce half increase at least, satisfy the requirement of GB standard manual operating physical force value≤60N.
Description of drawings

Fig. 2 is the end view of Fig. 1.
Among Fig. 1 Fig. 2: 1, cap; 2, bearing; 3, gear wheel; 4, housing; 5, transition gear; 6, pinion; 7, power shaft; 8 output shafts; 9, joystick patchhole.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Shown in Figure 2 as Fig. 1, a kind of device that alleviates isolator operation power, comprise the hand input of isolating switch operating mechanism decelerator position, the hand input of this decelerator position is connected with the output shaft 8 of a boxlike decelerator, this boxlike decelerator lower right is provided with the power shaft of band joystick jack 9 (square holes), with connect firmly a gear wheel 3 on the output shaft 8, connect firmly a pinion 6 on the power shaft, between the large and small gear by a transition gear 5 engagement.This device has double reduction, determines that gearratio is 2: 1: 1.Wherein the no-load voltage ratio of pinion and transition gear is 1: 1, is used to change transmission direction; The no-load voltage ratio of gear wheel and transition gear is 2: 1.Be used to reduce the output shaft rotating speed, make output shaft 8 rotating speeds slow down 1/2, alleviate 1/2 joystick operating physical force.
