Summary of the invention
Goal of the invention of the present utility model provides that a kind of flow conductivity is strong, fingertip is difficult for scaling loss, the electronic high voltage isolator of flexible, the mobile vehicle-mounted 20kA of rotary part, to solve the weak point that the existing indoor and outdoor high-voltage isolating switch that detects test usefulness exists.
In order to realize the foregoing invention purpose, the technical solution adopted in the utility model is: the electronic high voltage isolator of vehicle-mounted 20kA, it is characterized in that: comprise go-cart and be installed in lifting tank tower in the go-cart, one motor drive mechanism and two row's insulation columns are installed on the lifting tank tower, on every row's insulation column conductive plate are installed; A row conductive plate is equipped with the U-shaped conducting bracket therein, on another row's the conductive plate conductive rod is installed; Be movably installed with contact tube on the conductive rod, an end of contact tube is electrically connected with conductive plate by soft electrical band; Described motor drive mechanism comprises reduction box, power transmission shaft, connecting lever, the insulated tension pole of charged motivation; Reduction box is installed on the lifting tank tower, and power transmission shaft is bearing on the lifting tank tower by bearing, and the output shaft of one end and reduction box connects by shaft coupling; Connecting lever is fixed on the power transmission shaft appropriate location, and the lower end of itself and insulated tension pole is hinged respectively; The upper end of insulated tension pole is hinged with the turning rod that is connected on the contact tube respectively.
The utility model has the advantages that:
1, because the upset mode has been adopted in the water conservancy diversion loop, makes contact tube and U-shaped conducting bracket that a sliding process be arranged, when contact pressure is improved, also produce a self-cleaning function.
2, insulation column is vertically fixed on the lifting tank tower, does not do any rotation.Divide, close in the process impulsive force without any direction.
3, rotation, drive system reduce significantly, and be easy to maintenance.
4, simple in structure, the galvanic circle link is reliable.
5, can move transposition, the convenient use.
