Embodiment Construction

[0033] Such as figure 2 Shown. Disassembled and split combined overvoltage protector, including A, B, C, D four-phase cylindrical column, a plurality of resistors 8 are stacked in the cylindrical column, and the bottom of each phase cylindrical column is respectively provided for installation of the cylindrical column Bottom box 2, bottom box 2 with bottom box cover plate 1, and each phase cylinder column is a parallel double cylinder column, the lowest layer of the resistance plate in the double cylinder column passes through the wires 18 embedded in the corresponding bottom box Electrical connection. The uppermost layer of resistors in the double cylindrical column is electrically connected to the cable 16 drawn from the top of the double cylindrical column. The cable lead end of one of the cylindrical columns of each phase is electrically connected to the protected equipment of the power system. The cable lead-out end of the other cylindrical column serves as the midpoint,...

Abstract

The invention discloses a cylinder removal and split combination type overvoltage protector. The original combined type overvoltage protector is innovated structurally to be evolved into a novel product, namely the cylinder removal and split combination type overvoltage protector. In the cylinder removal and split combination type overvoltage protector, by a certain structural design, the height of cylinders of the overvoltage protector is reduced by a cylinder segmenting method to ensure the height of the installation space of the ordinary overvoltage protector, and a high-energy overvoltageprotector also can be loaded in the installation space. Simultaneously, due to the adoption of an A, B, C and D phase split production mode, the overvoltage protector can be lightly produced and transported, is not required to be integrally discarded if local problems are discovered during production and operation, and is more economic and environment-friendly due to split replacement, and the service life of the overvoltage protector is prolonged correspondingly.

Description

Technical field [0001] The invention relates to the field of overvoltage protectors, in particular to a split-column, split-body combined overvoltage protector. Background technique [0002] Because the energy absorption capacity of high-energy zinc oxide resistors is much larger than that of ordinary zinc oxide resistors, it greatly reduces the accidents such as burning or explosion of the over-voltage protector due to insufficient energy absorption capacity of the zinc oxide resistors. Therefore, the high-energy zinc oxide resistors are protected against overvoltage. There are more and more applications in the device. However, the withstand voltage value of each piece of high-energy resistors is much smaller than that of ordinary resistors, so the number of high-energy resistors in the same voltage level is far more than that of ordinary resistors, that is, the high-energy overvoltage protector cylinder assembled with high-energy resistors is more common The overvoltage protec...
