Breaker recloser equipped with opening-closing indication piece

Abstract

The invention provides a breaker recloser equipped with an opening-closing indication piece. The breaker recloser comprises a handle mechanism, a crank mechanism and a connecting rod, wherein the handle mechanism has a reciprocating motion state and produces tractive force in the reciprocating motion state; the crank mechanism has a rotating state and produces rotating force in the rotating state,and the tractive force is from the rotating force; the crank mechanism and the handle mechanism are assembled through the connecting rod. According to a product, the handle mechanism moves to producethe tractive force to provide a driving condition of the opening-closing of the product, and meanwhile, the opening-closing indication piece is driven to move to electrically indicate the breaking-closing state of the product in a multi-way manner, besides, the product is wholly assembled in a riveting manner, therefore, overall stability of the product is improved, and the service life of the product is prolonged.

Description

technical field [0001] The invention relates to the application field of a circuit breaker, in particular to a reclosing circuit breaker with an opening and closing indicator. Background technique [0002] When the overhead line fault is cleared, the circuit breaker is closed in a short time, which is called a recloser. At present, the traditional recloser basically includes a crank, a connecting rod and a handle. The crank drives the handle through the connecting rod to control the opening and closing. At present, the recloser The crank, connecting rod and handle are fastened by bolts, the fastening effect is poor, and it is easy to loosen and fall off during the working process, and the traditional reclosing crank uses the structure of the circlip to cooperate with the motor to achieve rotation. During the process, the circlip is easy to break, resulting in a short service life of the product, and the structure of the opening and closing indicator in the current circuit br...

[0002] When the overhead line fault is cleared, the circuit breaker is closed in a short time, which is called a recloser. At present, the traditional recloser basically includes a crank, a connecting rod and a handle. The crank drives the handle through the connecting rod to control the opening and closing. At present, the recloser The crank, connecting rod and handle are fastened by bolts, the fastening effect is poor, and it is easy to loosen and fall off during the working process, and the traditional reclosing crank uses the structure of the circlip to cooperate with the motor to achieve rotation. During the process, the circlip is easy to break, resulting in a short service life of the product, and the structure of the opening and closing indicator in the current circuit breaker reclosing is complicated, and the opening and closing of the opening and closing indicator is poor in short-circuit breaking capacity, resulting in poor overall stability of the product. a lot of
