Isolative double cooling electric surge tolerant resistor cabinet

Abstract

The invention discloses a manufacture method of an insulation double-cooling electric surge-resistant resistor cabinet. The resistor cabinet mainly comprises resistor cores, double-cooling boxes, an oil way part and a water way part. The resistor cores are metal strips with equal width and are produced by bypassed winding; when the resistor cores are installed, the side of the metal strip which is a large plane along the direction of length is perpendicular to the horizontal plane, and the end surface which is a small plane along the direction of length is parallel to the horizontal plane; the resistor cores are fixed in the oil cavity of the double-cooling box through ceramic rings and ceramic columns, and is led outside the double-cooling box through an insulating electrode to realize insulation. When in work, the insulating oil in the oil cavity transmits the heat energy generated by the resistor cores when power is on to the double-cooling box made of metal to realize internal cooling; the cooling water in the water tank of the double-cooling box takes away the heat of the double cooling box to realize external cooling; and the insulating oil in the oil cavity expands when heated before releasing pressure to a semi-capsule oil storage box through a pressure relief pipe. A plurality of layers of double cooling boxes are laminated and use one semi-capsule oil storage tank together, thereby the volume is reduced and an extra large insulation electric-surge-resistant resistance cabinet is conveniently assembled.

Description

Technical field [0001] The invention belongs to the field of high-power surge-resistant resistors. Background technique [0002] The original anti-surge resistor, one is to use a resistor body with large size and large heat capacity to withstand a large-energy surge. The volume increases with the increase of surge energy, so it is not suitable to be made into a super-high-power surge-resistant resistor. . The second is to achieve cooling by direct contact between the cooling water and the resistor body to reduce the volume; because the cooling water is in direct contact with the resistor body, the cooling water is charged, and there is a great safety hazard in use (especially in high-voltage circuits. ), and because water has a bypass effect, it is not allowed in some circuits. Contents of the invention [0003] In order to overcome the deficiencies of the original surge resistance resistor, the present invention introduces an insulating double-cooling surge resistance r...
