Abstract
The utility model discloses a movably connected conductor used in a high-voltage switch, which is characterized in that a spiral spring base is provided with a fixing groove; a spiral spring is arranged on the fixing groove; a static conductor is arranged on the spiral spring base; and a guiding piece is arranged on the spiral spring base and can contact with a movable conductor. The spiral spring and the movable conductor are in continuous surface contact. The design increases contacts, improves the flow capability, reduces the internal size of the product, simplifies the structure, improves the reliability, is not easy to scratch the conductor, and facilitates the installation and detachment.
Description
Technical field
The utility model relates to a kind of electric conductor, is specifically related to a kind of flexible connection electric conductor that is used in the high-voltage switch gear.
Background technology
Connection in the sulphur hexafloride circuit breaker equipment between the conductor adopts the Mume flower contact plug-in type to connect at present mostly.This connected mode only has a plurality of contact points, its in short-term through-current capability be subjected to certain restriction, more and more be not suitable for the trend of high voltage switchgear to the development of big capacity.This connected mode is owing to the power of holding tightly between conductor and the fingertip is provided by spring, and spring can distort in long-term certain temperature lower spring characteristic, the power of holding tightly changes, in order to satisfy certain through-current capability, every fingertip contact pressure need reach a bigger value, because contact pressure is bigger, easily scratches conductor, various, the complex structure of this kind connected mode part assembles comparatively loaded down with trivial details.Connect in addition the watchband of employing fingertip ways of connecting is also arranged, the elasticity of dependence watchband type fingertip makes between conductor, watchband fingertip and contact conductor three combines closely, this kind connected mode dovetail groove processed complex, the cost height, the scuffing of easily colliding with, and watchband fingertip installation frangibility, there is bigger hidden danger of quality.
The utility model content
The utility model has designed a kind of flexible connection electric conductor that is used in the high-voltage switch gear, and purpose is to reduce cost, convenient for assembly, improves reliability.
Technical solution of the present utility model:
A kind of flexible connection electric conductor that is used in the high-voltage switch gear, it is characterized in that: on the helical spring base holddown groove is set, helical spring is installed on the holddown groove, and quiet conductor is installed on the helical spring base, but guide is installed on the helical spring base and contacts with moving-conductor.
But be that continuous face contacts between described helical spring and the moving-conductor.
The beneficial effects of the utility model are: the design has increased contact point, has improved through-current capability, has dwindled the product inside dimension, simplifies the structure, and reliability is improved, and is difficult for the scratch conductor, is convenient to loading and unloading.
Description of drawings
Accompanying drawing 1 is the utility model cross-sectional view.
Embodiment
As shown in Figure 1, but electric conductor constitute by parts such as helical spring 3, helical spring seat 1, guide 2 moving-conductors 4.Helical spring 3 was packed in 2 holddown grooves in the helical spring seat 1 when assembling connected, and then the guide 2 of packing into, inserted movable bonding conductor 4 at last, utilized the elasticity of spring to make between conductor 4, helical spring 3 and helical spring seat 1 three and combined closely.
Concrete working method:
The course of work be electric current earlier by helical spring seat 1, and then by being contained in the helical spring 3 on the helical spring seat 1, but last electric current enters moving-conductor 4 by helical spring 3.Spring is out of shape under the effect of pressure, and contact area becomes big and compression can be provided.A plurality of guides 2 both can provide installs guiding, and the electric power that changes in the time of can reducing long-time running again is to the influence of conductor mechanical performance.
To sum up the utility model accomplishes the end in view.
Claims (2)
1. one kind is used for the interior flexible connection electric conductor of high-voltage switch gear, it is characterized in that: on the helical spring base holddown groove is set, helical spring is installed in the holddown groove, but moving-conductor be installed in the helical spring base, guide is installed on the helical spring base and contacts with conductor.
2. electric conductor as claimed in claim 1 is characterized in that: be that continuous face contacts between described helical spring and the conductor.
