Technical field
The utility model relates to field of electrical equipment, particularly relates 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.
