Abstract

um circuito elétrico para um disjuntor, compreendendo: um primeiro grupo de contato e um segundo grupo de contato. o primeiro grupo de contato compreende um primeiro contato estático (121) e um primeiro contato móvel (122), e o primeiro contato estático (121) é conectado a um terminal de entrada (101). o segundo grupo de contato compreende um segundo contato estático (131) e um segundo contato móvel (132), em que o primeiro contato móvel (122) e o segundo contato móvel (132) são conectados eletricamente, o segundo contato estático (131) é conectado a uma unidade de disparo (104), e a unidade de disparo (104) é conectada a um terminal de saída (105). o circuito elétrico para um disjuntor de acordo com uma ou mais modalidades da presente invenção conecta eletricamente uma pluralidade de contatos (122, 132, 222) móveis. a pluralidade de contatos móveis (122, 132, 222) é montada coaxialmente, e o segundo contato estático (131) é conectado, através do segundo contato móvel (132), ao terminal de saída (105), assegurando isolamento. sob a premissa de tornar a estrutura geral do disjuntor compacta e ocupar um pequeno espaço, o terminal de entrada e o terminal de saída estão dispostos nos dois lados, facilitando assim a fiação do disjuntor e outros equipamentos elétricos.an electrical circuit for a circuit breaker comprising: a first contact group and a second contact group. the first contact group comprises a first static contact (121) and a first moving contact (122), and the first static contact (121) is connected to an input terminal (101). the second contact group comprises a second static contact (131) and a second mobile contact (132), wherein the first mobile contact (122) and the second mobile contact (132) are electrically connected, the second static contact (131). is connected to a trip unit (104), and trip unit (104) is connected to an output terminal (105). The electrical circuit for a circuit breaker according to one or more embodiments of the present invention electrically connects a plurality of moving contacts (122, 132, 222). the plurality of movable contacts (122, 132, 222) are coaxially mounted, and the second static contact (131) is connected via the second movable contact (132) to the output terminal (105), ensuring isolation. Under the premise of making the overall circuit breaker structure compact and occupy a small space, the input terminal and output terminal are arranged on both sides, thus facilitating the circuit breaker wiring and other electrical equipment.
