Description
Technical field
The utility model relates to a kind of high voltage isolator and prevents contact rotating shaft from crossing heat structure, belongs to electrical equipment technical field.
Background technology
Current isolating switch because of load growth rapid, after transformer station's increase-volume, GW9--10 isolating switch running current is close to rated current, and isolating switch hot spot is concentrated, and repeatedly causes because contact rotating shaft etc. connects the overheated interruption maintenance of conducting position.
Utility model content
The utility model object is to provide a kind of high voltage isolator and prevents contact rotating shaft from crossing heat structure, adopts and increases the structure that contact number installs soft even conduction additional simultaneously, do not rely on merely spring pressure conduction, solve the problems referred to above existed in background technology.
The technical solution of the utility model is: a kind of high voltage isolator prevents contact rotating shaft from crossing heat structure, comprise rotating shaft, upper conductor, be flexible coupling wire, lower conductor, contact arm, column, contact one, contact two, contact three, connecting rod, retainer ring and insulator, described upper conductor, rotating shaft, be connected to each other by column and insulator after lower conductor connects successively, one end of contact arm is arranged on the side of column, contact one, contact two, contact three is arranged in order from top to bottom, pass through connecting rod, retainer ring is connected to each other formation sets of contacts, the other end of sets of contacts and contact arm is connected to each other, be flexible coupling wire one end and upper conductor is connected to each other, the other end and lower conductor are connected to each other.
The specification of described contact one, contact two, contact three is identical.
The beneficial effects of the utility model are: adopt and increase the structure that contact number installs soft even conduction additional simultaneously, do not rely on merely spring pressure conduction, make rotating shaft as additional conductive effect, no longer cause heating by running current, stop contact rotating shaft superheating phenomenon, reduce maintenance number of times, improve power supply reliability.
