Novel automatic reclosure double-worm driving mechanism

Abstract

The invention discloses a novel automatic reclosure double-worm driving mechanism. The novel automatic reclosure double-worm driving mechanism comprises a shell body and a cover body which are arranged on the side wall of an electric brake, wherein a driving motor is fixed in the shell body; a first worm sleeves an output shaft of the driving motor; a first intermediate shaft, a second intermediate shaft and an output shaft are arranged on the shell body; a first helical gear meshed with the first worm, and a second worm sleeve the first intermediate shaft; a second helical gear meshed with the second worm and an intermediate gear sleeve the second intermediate shaft; the output shaft passes through a machine shell, extends to the outer side of the machine shell and is connected with a switch of the electric brake; the output shaft is fixedly connected with a shifting shaft; an outer ring of the shifting shaft is provided with an output gear, meshed with the intermediate gear, in the sleeving way; lug wings are arranged on two sides of the shifting shaft; a vertical post abutted against the lug wings is arranged on the output gear. The novel automatic reclosure double-worm driving mechanism has the advantages of simple structure, reasonable design, low production cost, stable structure, long service life, high product market competitiveness and the like.

Description

technical field [0001] The invention relates to an automatic recloser, in particular to a novel automatic recloser double worm transmission mechanism. Background technique [0002] Automatic reclosing is widely used as an effective anti-accident measure on overhead line power transmission and overhead line power supply lines (cable transmission and power supply cannot be used), that is, when the line fails, after the relay protection trips the circuit breaker, the automatic reclosing device is short-circuited. Reclose the circuit breaker after the time interval. In most cases, line faults (such as lightning strikes, wind damage, etc.) are temporary, and the insulation performance (insulator and air gap) of the line can be restored after the circuit breaker trips, and the reclosing can be successful again, which improves the power supply of the power system. reliability. A small number of cases are permanent faults. After the automatic reclosing device operates, the relay p...
