Embodiment Construction

[0033] Such as figure 2 shown. Detachable column, split combined overvoltage protector, including A, B, C, D four-phase column, a plurality of resistors 8 are stacked in the column, and the bottom of each phase column is respectively provided with a column for installation Bottom box 2, bottom box 2 with bottom box cover plate 1, and each column is a parallel double column, and the lowest layer of resistors in the double column passes through the wires 18 buried in the corresponding bottom box Electrically connected, the uppermost resistance sheets in the double cylinders are respectively electrically connected to the cables 16 drawn from the top of the double cylinders, and the cable lead-out end of one of the cylinders in each phase is electrically connected to the protected equipment of the power system, The cable lead-out end of the other column is used as the midpoint, and the midpoints of different phase columns are electrically connected through the wire 15 in turn. ...

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 an overvoltage protector of split-column and combined type. Background technique [0002] Since the energy absorption capacity of high-energy zinc oxide resistors is much larger than that of ordinary zinc oxide resistors, it greatly reduces accidents such as burning or explosion of overvoltage protectors due to insufficient energy absorption capacity of zinc oxide resistors, so high-energy zinc oxide resistors are used in overvoltage protection. 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 much more than that of ordinary resistors, that is, the cylinder of high-energy overvoltage protector assembled with high-energy resistors is more ordinary. Surge protectors are much higher. ...
