Description

A kind of isolating switch intelligence contact
Technical field
The present invention relates to field of electrical equipment, particularly relate to a kind of isolation switch contact.
Background technology
At present, moving contact and fixed contact of isolating switch used both at home and abroad mainly contains two kinds, and comparatively early a kind of adopted scheme is with two or more spring straining both sides fingertips, makes fingertip and moving contact close contact.Newer scheme is that the arc-shaped spring piece adopting spring steel to make in fingertip both sides compresses fingertip.After a large amount of practicalities, find that these schemes exist following problem:
(1) do not take insulation measures between spring and static contact component or take measure but damage, electric current can be caused to flow through spring spring temper is followed the string, cause static contact component and moving contact component loose contact and generate heat; Spring is in for a long time and compresses or connect tight operating state and fatigue can occur, and along with the lengthening of running time is slowly followed the string, even can produce permanent deformation, cause contact bad.
(2) because the bolt of static contact component and moving contact component is due to long use, easily occur to loosen, cause loose contact between fingertip and moving contact, thus cause the loose contact of tactile face and produce superheating phenomenon.
(3) along with number of operations increases or the uneven meeting of the thickness of coating causes fingertip plating exfoliation, dew copper, thus cause contact overheated.
Because contact heating can cause isolating switch to lose efficacy, thus cause the generation of large area blackout, and transmission line power failure can produce heavy economic losses and severe social influence.For avoiding this phenomenon to occur, power department needs to strengthen inspection, and overhaul frequently in a large number also can the man power and material of at substantial.
Summary of the invention
Goal of the invention: the invention solves the problems referred to above, provides a kind of isolating switch intelligence contact.
Technical scheme: a kind of isolating switch intelligence contact of the present invention, comprises the static contact component and moving contact component that cooperatively interact; Described static contact component comprises the first contact tube, fixed contact fingertip, memory alloy spring sheet, button contact base; Described first contact tube is connected with described button contact base; Be oppositely arranged in the both sides of described button contact base and paired fixed contact fingertip is installed; The memory alloy spring sheet of arc is had in the fixed contact fingertip arranged outside of described paired setting; Described moving contact component comprises the second contact tube and moving contact body; Described moving contact body is connected with described second contact tube.
As a preferred embodiment of the present invention, described memory alloy spring sheet material is nickel titanium based memorial alloy.
As a preferred embodiment of the present invention, described fixed contact fingertip is one or more pairs of.
As a preferred embodiment of the present invention, described static contact component also comprises the first tube connector, the first bolt and the first memorial alloy packing ring; Described first tube connector is installed in described first contact tube, and is fixed by pin and described first contact tube; Described button contact base is connected with described first tube connector by described first bolt; Described first memorial alloy packing ring is installed between described first bolt and described button contact base, on sheathed and described first bolt of described first memorial alloy packing ring.
As a preferred embodiment of the present invention, described moving contact component also comprises the second tube connector, the second bolt and the second memorial alloy packing ring; Described second tube connector is installed in described second contact tube, and is fixed by pin and described second contact tube; Described moving contact body is connected with described second tube connector by described second bolt; Described second memorial alloy packing ring is installed between described second bolt and described moving contact body, on sheathed and described second bolt of described second memorial alloy packing ring.
As a preferred embodiment of the present invention, described fixed contact fingertip is bar shaped sheet fingertip.
As a preferred embodiment of the present invention, described memory alloy spring sheet is fixed on described button contact base by the 3rd bolt, and pads between described memory alloy spring sheet and described button contact base and be provided with the 3rd memorial alloy packing ring.
Beneficial effect: compared with prior art, its remarkable advantage is in the present invention: (1) memory alloy spring sheet can provide the elastic force continuing compressing, compresses fingertip, increases the pressure between fixed contact fingertip and moving contact body.Can not there is fatigue in fixed contact fingertip, follow the string, and causes loose contact; (2) first memorial alloy packing rings and the second memorial alloy packing ring can increase moving contact body and the second contact tube or the contact between fixed contact button contact base and the first contact tube when temperature rise recovers deformation, reduce contact resistance, reduce temperature rise heating; (3) the 3rd memorial alloy packing rings can recover deformation at adstante febre, increase memory alloy spring sheet, pressure between fixed contact fingertip and button contact base, prevent static contact component temperature rise deformation and cause the accident; (4) memorial alloy has good resistance to wear, and the spring leaf made of memorial alloy, without overlay coating process, can economize on resources, cut down finished cost, and avoids coating and reveals copper heating upon wear; (5) memorial alloy has good corrosion resistance, can avoid the erosion of steam, corrosivity dust and chemically reactive gas.
Nickel titanium based memorial alloy has good comprehensive mechanical property, excellent decay resistance and wear resistance, and the super-elasticity of uniqueness (~ 8%).As spring material, its combination property is far beyond common spring steel.The present invention's employing has good super-elasticity, the Ni-Ti-based shape memory alloy of thermal stability prepares high voltage isolator intelligence contact, substitute existing common spring steel plate, fundamentally solve because the overheated isolating switch Problem of Failure caused of fastening spring, thus greatly reduce the generation of isolating switch heating accident and large area blackout, for power department is saved a large amount of maintenance, safeguarded with man power and material, meet domestic electrical run enterprise in the urgent need to, avoid simultaneously due to transmission line have a power failure produce heavy economic losses and severe social influence.
