The technical scheme is that realized by following technical measures:A kind of transformer insulated device, including bottom Seat, supporting rack, connector, workbench and seal, the tube chamber welds with base are installed on the bottom surface of supporting rack, the connector with For workbench on same center line, the seal includes case, pure porcelain casing tube, capacitance graded bushing, oil filled bushing, conducting rod, The outer surface of the capacitance graded bushing and oil filled bushing is nested, and the case is connected with the outer surface of pure porcelain casing tube, described pure The outer surface of porcelain bushing shell and capacitance graded bushing fits, and is provided with multiple discoidal tiles, true procelain set on pure porcelain casing tube in an axial direction Pipe includes upper porcelain piece and lower ceramic part, and one end of the lower ceramic part is connected with pedestal and the other end is connected through a screw thread with upper porcelain piece, The junction of the upper porcelain piece and lower ceramic part offers wiring hole and conducting rod is arranged in the wiring hole, and the conducting rod is embedding Enter to be installed on the inside of oil filled bushing, the outer surface of the case and connector is mutually welded.
Here is the further optimization or/and improvement to foregoing invention technical solution:
Preferably, the outer diameter of the upper porcelain piece is more than the outer diameter of the lower ceramic part.
Preferably, the upper porcelain piece is provided with shield close to one end of lower ceramic part.
Preferably, the shield is arranged in umbrella shape and the opening of the shield of the umbrella shape is towards lower ceramic part.
Preferably, the junction of the upper porcelain piece and lower ceramic part is provided with sealing ring.
The seal insulation performance that the present invention solves the prior art is poor, it may appear that load current circulates and damages for a long time The phenomenon that bad, corrosion, the problem that causes transformer usage time short.The present invention has good thermostabilization by the way that pure porcelain casing tube is arranged Property, it is not easy to generate heat, is connected through a screw thread by upper porcelain piece and lower ceramic part and forms the space of relative closure to place conducting rod, make described Conducting rod will not be directly exposed in air, it is avoided to be caused by the adhesion of getting rusty of conductive metal caused by air, moisture corrosion Spark only need to can reach fixed, locking cable in installing and dismounting by twisting upper porcelain piece, easy to operate.Capacitance graded bushing As major insulation equipment, the leakage of power supply is effectively completely cut off, the good airproof performance of oil filled bushing has completely cut off the mutually outflow of power supply Logical, the conducting rod in oil filled bushing is introduced to the electric current in transformer the earth, disperses the electric current of a part of power transformer, It good insulation preformance and is hardly damaged, more safety durable.
