Definitions

  • the invention relates to an outlet structure of reactor, particularly a high voltage outlet structure of an ultra-high voltage shunt reactor.
  • a high voltage outlet structure of an ultra-high voltage of 1100kilovolt shunt reactor adopts an indirect outlet structure, i.e. before connected to a terminal block of a sleeve, the high voltage outlet enters an outlet device consisting of an insulator, a copper pipe, a voltage sharing ball and so on.
  • the outlet device and sleeve are mounted in a "trunk type" ascending seat on the outer side of the oil tank independently.
  • the entire ascending seat is about 16 tons in weight.
  • the body of the reactor vibrates greatly; located independently on the outer side of the oil tank body, the high voltage "trunk type" ascending seat exerts huge shearing action on the oil tank.
  • the invention provides a high voltage outlet structure of an ultra-high voltage shunt reactor which guarantees electrical strength and reliable insulation of outlet of 1100kilovolt, and also guarantees mounting of the outlet structure and a sleeve on an oil tank body, thereby avoiding shearing action of a high voltage ascending seat on the oil tank body.
  • a high voltage outlet structure of an ultra-high voltage shunt reactor comprises a voltage sharing pipe and a voltage sharing ball connected to the tail end of the voltage sharing pipe.
  • the high voltage outlet structure of an ultra-high voltage shunt reactor further comprises an insulating paper cylinder on the outer side of the voltage sharing ball, a ⁇ -type paperboard on the outer side of the insulating paper cylinder, and a lead supporting structure. Three layers of insulating paper pulp and two layers of supporting strips are disposed on the outer side of the voltage sharing ball at intervals.
  • the insulating paper cylinder is mounted below an ascending seat, and an opening is provided below the insulating paper cylinder.
  • the lead supporting structure clamps the voltage sharing pipe by arranging grooving paperboards in a staggered mode.
  • a thick paperboard configured to fix the grooving paperboards is disposed below the grooving paperboards.
  • the lower part of the thick paperboard is supported by an insulating conductor grip.
  • the outlet structure guarantees electrical strength of outlet of 1100kilovolt by the insulating paper cylinder and ⁇ -type paperboard on the outer side of the voltage sharing ball.
  • the voltage sharing pipe and voltage sharing ball are supported by the lead supporting structure outside the voltage sharing pipe.
  • the opening below the insulating paper cylinder steers clear of the lead supporting structure.
  • the lead supporting structure clamps the voltage sharing pipe by arranging three layers of grooving paperboards in a staggered mode; its lower part uses two thick paperboards to drag three grooving paperboards used for clamping the voltage sharing pipe.
  • the lower part of the thick paperboards is supported by a formed insulating conductor grip to guarantee the stability of the outlet structure.
  • a sleeve is inserted in the upper part of the voltage sharing ball.
  • the voltage sharing pipe is L-type copper pipe, with its tail ends inserted in the voltage sharing ball. Led out from the middle of the high voltage winding, the high voltage lead penetrates from the head end of the L-type copper pipe and is crimped with the leader cable in the L-type copper pipe, then passing the voltage sharing ball and led out from the sleeve.
  • the L-type copper pipe is covered by paper pulp and insulating layer.
  • the insulating paper cylinder has four layers from inside to outside.
  • the ⁇ -type paperboard has four layers from inside to outside.
  • the two ends of the four-layer ⁇ -type paperboard are fixed to the oil tank by the supporting strip and insulating screw, etc., and the middle of the four-layer ⁇ -type paperboard is fixed by the cushion block and insulating screw, etc..
  • the outer three layers of the insulating paper cylinder are fixed at the top, and the innermost layer is fixed at the bottom.
