Embodiment Construction

[0014] In order to further reveal the technical solutions of the present invention, the following describes the implementation of the present invention in detail in conjunction with the accompanying drawings: figure 1 As shown in the figure, the folding-arm isolating switch capable of switching from different angles includes an upper conductive part 1 and a rotating porcelain bottle 2 , and a pillar porcelain bottle 3 is provided at the lower end of the rotating porcelain bottle 2 . An angle conversion device 4 is provided between the upper conductive part 1 and the rotating porcelain bottle 2. The angle conversion device 4 is an angle converter, which can also be a gear or a crank arm, but it has an impact on the stability of the product. Not as good as angle converters.

[0015] Such as figure 2 As shown, the input shaft 5 of the angle conversion device 4 is docked with the rotary porcelain bottle 2 , and the output shaft 6 of the angle conversion device 4 is docked with t...

Abstract

The invention discloses a folding arm type disconnecting switch capable of achieving transformation at different angles. The folding arm type disconnecting switch capable of achieving the transformation at different angles comprises an upper conductive part and a rotary porcelain bottle. An angle transformation device is arranged between the upper conductive part and the rotary porcelain bottle, the input shaft of the angel transformation device is in butt joint with the rotary porcelain bottle, and the output shaft of the angel transformation device is in butt joint with a rotary crank arm of the upper conductive part. According to the folding arm type disconnecting switch capable of achieving the transformation at different angles, the angle transformation device is arranged between the upper conductive part and the rotary porcelain bottle, butt-joint between an old product and a new product is achieved, the structural defect of the old product is overcome fundamentally, partial replacement can be achieved, the reliability of operation is achieved, and cost is saved.

Description

technical field [0001] The invention relates to a knuckle arm type isolating switch, in particular to a knuckle arm type isolating switch which can realize conversion of different angles. Background technique [0002] At present, there are more than 2,400 sets of folding arm type isolating switches operating in our province, tens of thousands of sets in the country, and domestic models include GW10, GW11, GW16, GW17 (hereinafter referred to as old products), etc. The failure rate of this series of products is high. Vicious accidents such as opening and closing occur frequently. The fault-prone parts mainly occur in the upper conductive part. Due to the complex structure of this part, there is no condition for dismantling and overhauling on site. Returning to the manufacturer for overhaul will also incur higher overhaul costs. More importantly, the product has structural defects, overhaul cannot solve the problem fundamentally, and some parts have been replaced as a whole. ...
