Definitions

  • the present invention relates to the technical field of circuit breakers, and more particularly, to an operation mechanism of a 2P2M electromagnetic residual current circuit breaker with overcurrent protection (RCBO).
  • RCBO overcurrent protection
  • RCBO also called earth leakage circuit breaker or ground fault circuit interrupter
  • the RCBO is mainly used to protect a person in danger when current leakage occurs in a device, and may be used to protect a line or a motor to avoid overload or short circuit, or may be used in normal cases when a line is infrequently converted and started.
  • the RCBO usually includes a housing.
  • a circuit breaker apparatus and a current leakage protection apparatus are distributed in the housing.
  • the circuit breaker apparatus is used to control connection or disconnection of a movable contact and a fixed contact when short circuit or overload occurs or a line is infrequently started.
  • the current leakage protection apparatus is used to control the connection or disconnection of the movable contact and the fixed contact when current leakage occurs.
  • the circuit breaker apparatus usually includes an operation mechanism, a thermal tripping mechanism, an electromagnetic tripping mechanism, and an arc extinguishing system.
  • the operation mechanism includes a handle, a contact lever, and a latch.
  • the connection or disconnection of the movable contact and the fixed contact may be controlled through a linkage structure among the handle, the contact lever, and the latch.
  • the latch is used to link the current leakage protection apparatus to the operation mechanism, to control the connection or disconnection of the movable contact and the fixed contact when current leakage occurs.
  • circuit breaker in the prior art has a large quantity of components.
  • each circuit breaker is connected to one handle linkage mechanism for operation.
  • handle linkage mechanisms Document CN 111 293 009 A discloses an operation mechanism according to the preamble of claim 1.
  • the present invention provides an operation mechanism of a 2P2M electromagnetic RCBO in which a single handle may control multiple circuit breakers. This simplifies a structure and reduces the overall structural complicity of the circuit breaker and a quantity of components so that costs are reduced and processing and assembly are convenient.
  • An operation mechanism of a 2P2M electromagnetic RCBO including a handle and a connection rod with one end linked to the handle, where the other end of the connection rod opposite to the end linked to the handle is linked to a contact lever; a first hinging and linking shaft with one end hinged to a housing of the circuit breaker is disposed in the middle part of the contact lever; a first latch hinged to one end of the first hinging and linking shaft is linked to one side of the contact lever; an end of the first latch intermittently abuts against and is linked to the contact lever, and a second latch hinged to the other end of the first hinging and linking shaft is linked to the other side of the contact lever opposite to the side linked to the first latch; the other end of the contact lever opposite to the end linked to the connection rod is provided with a second hinging and linking shaft; the side of the contact lever towards the first latch is linked to a first movable contact, where the first movable contact is hinged
