Abstract
trata-se de um mecanismo de operação de um disjuntor miniatura que compreende um manípulo, uma haste de conexão de acionamento, um contato estacionário e um contato móvel, e compreende adicionalmente uma mola de tensão e uma alavanca de desarme, sendo que uma extremidade da haste de conexão de acionamento é articulada com o manípulo, a outra extremidade da haste de conexão de acionamento é combinada com o contato móvel, uma extremidade da mola de tensão é fixada em um alojamento e a outra extremidade da mola de tensão é conectada ao contato móvel; o contato móvel é acionado pela mola de tensão e a haste de conexão de acionamento conjuntamente para fornecer uma pressão de contato e uma força elástica de distensão necessárias para garantir a confiabilidade de contato elétrico para fechar o contato móvel e o contato estacionário, e a mola de tensão fornece uma força elástica de armazenamento de energia necessária para a reinicialização do mecanismo para separar o contato móvel do contato estacionário; e a alavanca de desarme é disposta no contato móvel e é usada para controlar a cooperação de travamento e destravamento entre a haste de conexão de acionamento e o contato móvel, sendo que, quando uma falha ocorre automaticamente, a alavanca de desarme separa a haste de conexão de acionamento do contato móvel para liberar automaticamente o mecanismo de operação. o mecanismo pode simplificar de modo eficaz a estrutura, reduzir o custo de fabricação, melhorar a eficiência de produção e otimizar o desempenho mecânico.it is a miniature circuit breaker operating mechanism comprising a handle, a connecting rod, a stationary contact and a movable contact, and additionally comprises a tension spring and a release lever, one end of which drive connection rod is articulated with the handle, the other end of the drive connection rod is combined with the movable contact, one end of the tension spring is fixed in a housing and the other end of the tension spring is connected to the contact mobile; the movable contact is actuated by the tension spring and the actuating connecting rod together to provide the contact pressure and elastic stretching force necessary to ensure the reliability of electrical contact to close the movable contact and the stationary contact, and the spring voltage supply provides an elastic energy storage force required to reset the mechanism to separate the mobile contact from the stationary contact; and the release lever is arranged on the movable contact and is used to control the locking and unlocking cooperation between the actuation connection rod and the movable contact, and when a failure occurs automatically, the disarm lever separates the drive connection of the mobile contact to automatically release the operating mechanism. the mechanism can effectively simplify the structure, reduce manufacturing costs, improve production efficiency and optimize mechanical performance.
