Measuring auxiliary device 7 further includes auxiliary shell 73, and unlike the various embodiments described above, auxiliary shell 73 passes through itself
Second hook 731 is fixed on main body module 70, rather than is directly fixed on the end of incoming cables 60 of breaker 6.This embodiment is applicable in
In the situation of card slot deficiency on the end of incoming cables of breaker, auxiliary shell 73 can be used to supportive body module, protection wiring and make total
Body is more attractive.
In addition, breaker either miniature circuit breaker or breaker of plastic casing or frame circuit breaker, in different embodiments
In, breaker and metering install the fixation of module additional and are electrically connected mode difference also not substantially, therefore the present invention not with
This is limited.
Metering auxiliary device and intelligent breaker based on breaker of the invention, by the mechanical connection of innovative design and
Electric connection mode can complete at lower cost and conveniently and efficiently intelligence on the basis of traditional breaker and distribution box
Change the add-assembly of metering module, and occupied space is smaller, fixed, the large-scale popularization for being very suitable for intelligent breaker is answered
With.
The present invention installs the buckle in module additional by metering and is embedded in the card accessory of breaker in terms of mechanical connecting structure
And locking part, so that metering auxiliary device is combined into one with conventional circuit breaker.The present invention is in the confession for solving metering auxiliary device
Electric aspect, using two class ways to take power: one is with the inserted sheet on circuit module, be directly connected to breaker to connect wiring in power port
Column lock;Another kind is to use spring ejector pin connector, and breaker is taken the bullet on binding post screw and circuit module in power port
Piece is electrically connected.The present invention is in the embodiment using spring ejector pin connector, can be in addition to aforementioned techniques effect
Realize the transformation repacking that do not have a power failure of intelligent breaker.
The present invention is described by above-mentioned related embodiment, however above-described embodiment is only to implement example of the invention.
It must be noted that the embodiment disclosed is not limiting as the scope of the present invention.On the contrary, do not depart from spirit of the invention and
