Summary of the invention
The technical problem that the utility model solves is to provide a kind of combined high pressure isolating switch, and it adopts the mode of combined integratedization three-phase ganged, has simple to operate, safe and reliable, compact conformation, switch advantage flexibly.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of combined high pressure isolating switch, it is characterized in that: by cross-arm support, be fixed on 3 longitudinal carriers that cross-arm support distributes with cross-arm support vertical, be arranged on the three-phase linked switch composition on longitudinal carrier, described three-phase linked switch comprises the universal driving shaft be fixed on cross-arm support, be arranged on the operating grip in the middle part of universal driving shaft, be positioned at the link insulator be articulated and connected by crank with universal driving shaft below longitudinal carrier, be positioned at the isolation switch below link insulator, described isolation switch two ends are arranged on below longitudinal carrier by disconnecting link insulator, isolation switch one end and disconnecting link insulator adopt fixed contact to be connected, the other end and disconnecting link insulator adopt moving contact to be connected, described fixed contact, moving contact are all connected with cable by wiring insulator.
As the further improvement of the technical program, be provided with above described universal driving shaft and prevent falling power assistant spring device.
As the further improvement of the technical program, outside described moving contact, be provided with arc extinguishing pin.
As the further improvement of the technical program, described operating grip is provided with 2, and one end of 2 operating grips is connected V-shaped distribution with universal driving shaft.
Compared with prior art, the utility model combined high pressure isolating switch point, zygonema road time three-phase ganged,
Operate simple and fast more, efficiently solve the problem that single-pole switch processing ease produces adjacent inter-phase arc short circuit, cross-arm support, longitudinal carrier and three-phase linked switch adopt integrated combination design, greatly reduce the use amount of electric armour clamp, decrease the operating time of workman's installation and maintenance.Prevent that falling the decapacitation of power assistant spring device prevents outside isolation switch accidental fall, also serves the effect of divide-shut brake power-assisted simultaneously, reduce operating grip operation resistance.Arc extinguishing pin can realize the charged breaking-closing operating of underload.
