Description
Technical Field

Background
The single-stage circuit breaker is a low-voltage terminal electric appliance widely used in industrial and civil fields, and mainly comprises an operating mechanism, a contact system, an arc extinguishing system, a magnetic tripping system, a thermal tripping system, a shell and the like. The operating mechanism generally comprises a handle and at least one link, and the contact system generally comprises a movable contact and a stationary contact. In the existing single-stage circuit breaker, the moving contact is usually connected with a connecting rod and is driven by the connecting rod to be in contact with or disconnected from the fixed contact. Sometimes, for the purpose of description, the handle, the link and the movable contact are also referred to as an operating mechanism, and the names of the components of the circuit breaker are not necessarily limited.
In the existing single-stage circuit breaker, an operating mechanism is mostly a moving contact, and due to ablation in current breaking and abrasion of the contact caused by daily use, and due to the fact that the size of the contact is limited by factors such as cost and space, the circuit breaker with the single-moving contact is greatly limited in breaking capacity, service life, temperature rise and other performances. In order to increase the rated current of the housing of the single-stage circuit breaker, the current density may be decreased by increasing the volume of the circuit breaker or increasing the cross-sectional area of the internal conductor.
The circuit breaker is characterized in that when the contact of the circuit breaker is opened and closed, the circuit breaker can be opened and closed, and the opening and closing of the circuit breaker are realized through an operating mechanism; for a switch cabinet, the existing circuit breaker operating mechanism has unstable performance, large occupied space and high manufacturing cost, so that the structure of the circuit breaker operating mechanism needs to be adjusted.
Chinese patent application with application publication No. CN106683919A and application publication No. 2017.05.17 discloses an operating mechanism and a switch device using the operating mechanism, wherein the switch device comprises a transmission shaft, a transmission crank arm arranged on the transmission shaft, and an insulating pull rod connecting the transmission crank arm and a moving contact, one end of the insulating pull rod is hinged to the transmission crank arm through a sickle crank arm, and the other end of the insulating pull rod is fixedly connected to the moving contact. When the switching device is used, the insulating pull rod is hinged with the transmission crank arm through the sickle crank arm, the other end of the insulating pull rod is fixedly connected with the moving contact, and the insulating pull rod moves linearly in the insulating column along the axial direction of the insulating column. But because the length of insulating pull rod is longer, when the circuit breaker carries out the divide-shut brake operation, the insulating pull rod atress can produce the unstability shake phenomenon.
The utility model discloses a chinese utility model patent that the grant bulletin number is CN204927167U, and the grant bulletin date is 2015.12.30 discloses a direction strutting arrangement and use device's pillar, knob insulator type circuit breaker, and this knob insulator type circuit breaker includes two sections porcelain bushing bodies, connects through direction strutting arrangement between two sections porcelain bushing bodies, and direction strutting arrangement includes the positioning disk, and the positioning disk is the basin formula structure, and open at the pelvic floor middle part has the guiding hole that supplies insulating pull rod to pass.
