Description
Technical field
The utility model relates to a kind of parts of high-pressure air circuit breaker, specifically a kind of high voltage isolator low resistance electric installation.
Background technology
The central breakaway-element high voltage isolator that uses on the high-voltage fence, its basic comprising include electric installation, insulating mechanism, transmission mechanism and operating means four parts.Wherein, electric installation is the core of high voltage isolator, and the quality of its structure can directly have influence on the serviceability of high voltage isolator.The electric installation of high voltage isolator is made up of a plurality of elements such as binding post, contact rod, conductive strips and conductive arms.Owing to be to realize the conduction task by a plurality of elements, thereby the contact-making surface of element is many, on each contact-making surface, all can produce certain contact resistance, the resistance increase that these contact resistances add up and can cause the galvanic circle, and contact-making surface of every increase in the electric installation of high voltage isolator, will increase a heat generating spot, also with regard to the corresponding weak spot that increases the galvanic circle.
In order to eliminate these weak spots, the way of taking usually, the one, increase the sectional area of conducting element, the 2nd, increase the silver-plated area of conducting element, reduce contact resistance to reach, eliminate heating, guarantee the purpose of discharge capacity.Yet above-mentioned way can improve the manufacturing cost of product undoubtedly.
In addition, mostly be the mode that is flexible coupling that is electrically connected by soft conductive strips, the binding post rotation on contact rod top between the conductive arm in the existing high voltage isolator electric installation and the contact rod.The anglec of rotation of contact rod is subjected to the restriction of soft conductive strips length.In particular cases the anglec of rotation of contact rod can surpass angle allowable, and the active force that makes soft conductive strips also will bear extruding or stretch causes the fracture and the damage of soft conductive strips.
The utility model content
The purpose of this utility model just provides a kind of high voltage isolator low resistance electric installation, to reduce the contact resistance of electric installation, improves the functional reliability of high voltage isolator.
The utility model is achieved in that a kind of high voltage isolator low resistance electric installation, include binding post, contact rod and conductive arm, the rear end of described conductive arm is the annulus circle of suit conductive shaft, is crimped with some conductive reeds between the annulus circle of described conductive arm and described contact rod; Conductive reed is arranged in order the formation annular, and the annulus circle with conductive shaft and conductive arm closely contacts respectively.
The utility model changes the rear end of fingertip conductive arm in the high voltage isolator and contact conductive arm respectively and becomes the annulus circle, a plurality of conductive reeds of arranging by interior dress annular, contact rod is squeezed in the centre of annulus circle, contact rod is subjected to the even extruding of conductive reed, in 360 ° rotating range, all closely contact with conductive reed, like this, just make contact rod have very strong rotation flexibility, make electric installation have reliable low-resistance electric conductive performance, avoided the anglec of rotation restriction of contact rod and the device that therefore causes to damage thus.
Described conductive reed is to be connected to side Zhang Yi in the both sides of a tube wall, in the end of side Zhang Yi the back bending section is arranged.This structure has the possibility that annulus is arranged, and makes side Zhang Yi have stronger elasticity.
On the tube wall of described conductive reed, have a slide breach.Its effect one is the elasticity that further improves conductive reed, the 2nd, and help annulus and arrange, and can improve contact point between the conductive reed, to increase current capacity.
Described binding post and described contact rod are the structure of one up and down.Like this, reduce the contact site, reduced contact resistance, improved the functional reliability of electric installation.
The utility model is compared with the electric installation of the high voltage isolator of existing equal current capacity, its compact conformation, and functional reliability is strong, and contact resistance is little.The material of the used conductive reed of whole device is less than the materials of soft conductive strips, and the diameter of contact rod also can effectively reduce, and therefore, has both saved copper consumption, has also reduced installation cost.
