A combination of croissants

Abstract

The invention discloses a novel cavel combination gap. The novel cavel combination gap comprises an H-shaped steel base, a first base sliding block, a second base sliding block, a third base sliding block, a cavel gap combination, an adjustable supporting column, a metal plate and a metal plate supporting seat. The first base sliding block, the second base sliding block and the third base sliding block are respectively embedded in the H-shaped steel base, and can slide along the H-shaped steel base; a first supporting column insulator is carried by the first base sliding block; the second base sliding block is used for supporting a second supporting column insulator; the metal plate is fixed to the second supporting column insulator through the metal plate supporting seat; the third base sliding block is used for carrying the adjustable supporting column; the cavel gap combination comprises a first insulator supporting column, a first cavel electrode arranged on the first insulator supporting column, the adjustable supporting column and a second cavel electrode arranged on the adjustable supporting column. Due to the implement of the novel cavel combination gap, the metal plate is additionally arranged between the cavel electrodes, and accordingly gap thunder and lightning withstand voltages of the gap under the same gap length condition can be increased and the power-frequency breakdown voltages of the gap can be reduced.

Description

Technical field [0001] The present invention relates to the field of electric power technology, in particular to a horn combined gap. Background technique [0002] At present, most of the protective gaps used in the power industry are single rod-rod gaps or claw gaps, etc. However, this single gap has relatively fixed electrical characteristics due to the same discharge mechanism. Due to its special structure and complicated discharge rules, combined electrics have been studied less. Therefore, it is necessary to provide a combined gap, which can change the tolerance amplitude of different waveform voltages of a single gap and improve its electrical characteristics. Summary of the invention [0003] In order to solve the above technical problems, the embodiment of the present invention provides a claw horn combination gap, which includes: an I-beam base, a first base slider, a second base slider, a third base slider, a claw gap combination, and an adjustable pillar , Metal plate...

AI Technical Summary

Problems solved by technology

[0002] At present, the protection gaps used in the power industry are mostly single rod-rod gaps or horn gaps, etc., but the electrical characteristics of this single gap are relatively fixed due to the same discharge mechanism.

Due to its special structure and complex discharge law, the combined electrical system is rarely studied.
