Embodiment Construction
[0039] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0040] The invention provides an intelligent monitoring molded case circuit breaker plug-in universal device, which is obviously superior to other structures. It not only has the advantages of convenient installation and disassembly, but also uses wave-shaped flexible contacts for the conductive plug-in parts, which have good contact force and comparative Small insertion and extraction force; product modularization, small size, integrated secondary line circuit board, easy operation Rotary mechanical linkage, overall push-pull insertion and extraction method, pulling out ...

The invention provides an insertion and extraction general configuration device for an intelligent monitoring plastic-shell circuit breaker. The device comprises a closed bus seat, a plastic-shell circuit breaker insertion and extraction general configuration device and a rotary type mechanical connecting rod. When the closed type bus seat and the plastic-shell circuit breaker insertion and extraction general configuration device are locked through the rotary type mechanical connecting rod, a three-phase wire incoming bus bar is inserted into a three-phase wire incoming contact finger insert. Meanwhile, a three-phase wire outgoing bus bar is inserted into a three-phase wire outgoing contact finger contact, so that the plastic-shell circuit breaker is switched on. When the closed type bus seat and the plastic-shell circuit breaker insertion and extraction general configuration device are unlocked through the rotary mechanical connecting rod, the three-phase wire incoming bus bar is disengaged from the three-phase wire incoming contact finger insert. Meanwhile, the three-phase wire outgoing bus bar is disengaged from the three-phase wire outgoing contact finger contact, so that the plastic-shell circuit breaker is switched off. The closed type bus seat and the plastic-shell circuit breaker insertion and extraction general configuration device are locked through the rotary type mechanical connecting rod, and the advantages of easy installation and easy disassembly are realized.
Description
technical field [0001] The invention belongs to the technical field of assembly of molded case circuit breakers, and in particular relates to an intelligent monitoring molded case circuit breaker plug-and-pull universal device. Background technique [0002] At present, in the fields of new energy, power transmission and transformation, data room, industrial power consumption, etc., most power distribution products are equipped with molded case circuit breakers and monitoring modules, through which the abnormal power supply can be cut off through the molded case circuit breakers, so as to ensure the safety of power supply; through The monitoring module realizes the collection of electricity consumption data. In the prior art, both the molded case circuit breaker and the monitoring module are fixedly installed with the busbar seat, such as the screw installation method. This installation method mainly has the following disadvantages: [0003] The screw installation method has...
