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
The present invention relates to a kind of folding-jib isolating switch, particularly relate to a kind of folding-jib isolating switch of realizing the different angles conversion.
Background technology
At present, have 2400 at the folding-jib isolating switch of our province operation more and to organize, the whole nation has tens thousand of groups, and domestic model has GW10, GW11, GW16, GW17(hereinafter to be referred as old product) etc., this series of products failure rate is high, and is inseparable, close not first-class serious accident and occur frequently.The fault predilection site mainly occurs in current-carrying part, because this part-structure is complicated, does not possess at the scene the condition of disintegration overhaul, and the return-to-factory overhaul also has higher overhaul cost.The more important thing is that there is structural defective in this product, overhaul can not be dealt with problems at all, and some place is integral replacing.
A few years ago, have producer to release renewal product GW22B, GW23B Series Switch-disconnector (hereinafter to be referred as new product), its properity all is better than old product, and beginning in 2007 just has application at our province.Operational data shows that its failure rate far below old product, especially goes up current-carrying part, and design concept is advanced, has overcome some defectives of old product fully.
If the upper conduction that substitutes old product with the upper current-carrying part of new product both can improve the operational reliability of product, the expense that can save again integral replacing.But the rotational angle of old product motor drive mechanism is 90 °, and the driving angle that new product needs is 135 °, and therefore upper current-carrying part can not directly be replaced.
Summary of the invention
For the deficiencies in the prior art, the object of the invention is to, a kind of folding-jib isolating switch of realizing the different angles conversion is provided, realize the docking of new old product with a kind of relatively simple angle conversion device, fundamentally solve the fault of construction of old product, can realize local replacing, improve reliability of operation, but again cost saving.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the folding-jib isolating switch that can realize the different angles conversion, comprise current-carrying part and rotation porcelain vase, it is characterized in that: be provided with angle conversion device between current-carrying part and the rotation porcelain vase on described, the power shaft of described angle conversion device docks with described rotation porcelain vase, and the output shaft of described angle conversion device docks with the rotation connecting lever of described upper current-carrying part.
The aforesaid folding-jib isolating switch of realizing the different angles conversion, it is characterized in that: described angle conversion device is angle converter.
The aforesaid folding-jib isolating switch of realizing the different angles conversion, it is characterized in that: described angle conversion device is gear or connecting lever.
The aforesaid folding-jib isolating switch of realizing the different angles conversion is characterized in that: be provided with rebound between the rotation connecting lever of described angle conversion device and described upper current-carrying part.
The aforesaid folding-jib isolating switch of realizing the different angles conversion, it is characterized in that: the lower end of described rotation porcelain vase is provided with support insulator.
The invention has the beneficial effects as follows: by between upper current-carrying part and rotation porcelain vase, angle conversion device being set, realize the docking of new old product, fundamentally solved the fault of construction of old product, can realize local replacing, improve reliability of operation, saved expense.
Description of drawings
Fig. 1 is structural representation of the present invention;
Fig. 2 is the structural representation of angle conversion device among the present invention.
Embodiment
For further disclosing technical scheme of the present invention, describe embodiments of the present invention in detail below in conjunction with accompanying drawing: as shown in Figure 1, can realize the folding-jib isolating switch of different angles conversion, comprise current-carrying part 1 and rotation porcelain vase 2, the lower end of described rotation porcelain vase 2 is provided with support insulator 3.Be provided with angle conversion device 4 between current-carrying part 1 and the rotation porcelain vase 2 on described, described angle conversion device 4 be angle converter, can also be gear or connecting lever, but stable influential to product, too late angle converter effective.
As shown in Figure 2, the power shaft 5 of described angle conversion device 4 docks with described rotation porcelain vase 2, and the output shaft 6 of described angle conversion device 4 docks with the rotation connecting lever 7 of described upper current-carrying part 1.
Be provided with rebound 8 between the rotation connecting lever 7 of described angle conversion device 4 and described upper current-carrying part 1.
The rotational angle of old product motor drive mechanism is 90 °, and the driving angle that new product needs is 135 °, and upper current-carrying part can not directly be replaced.Will change its kinetic characteristic if the rotational angle of new product is designed to 90 °, affect its reliability.If study a kind of angle conversion device, with 135 ° of 90 ° of conversions, just can change with the new product current-carrying part of maturation.
The present invention realizes the docking of new old product by between upper current-carrying part and rotation porcelain vase angle conversion device being set, and has fundamentally solved the fault of construction of old product, can realize local replacing, has improved reliability of operation, has saved expense.
More than by description of listed embodiment, the basic ideas and basic principles of the present invention have been set forth.But the present invention never is limited to above-mentioned listed execution mode, and every equivalent variations, improvement and deliberately of inferior quality behavior of change of doing based on technical scheme of the present invention all should belong to protection scope of the present invention.
