Background technology
RCCB includes operational module and ZCT, and live wire and the zero line of RCCB are intended to through zero sequence
Transformer, and ZCT is normally located in the operational module of RCCB, so mutual when operational module or zero sequence
When sensor damages, whole RCCB the most directly is scrapped, simultaneously because fasten between operational module and ZCT
Connect, the same inconvenient reparation that RCCB is carried out some small problems, bring inconvenience, one to actual use
Determine to improve in degree the production cost of enterprise, bring deleterious effect to the development of enterprise.
Summary of the invention
The invention aims to overcome the deficiencies in the prior art to provide a kind of simple in construction, it is possible to avoid zero formula mutual inductance
After device damage, whole product rejection moulds shell RCCB.
For reaching above-mentioned purpose, the technical solution used in the present invention is: one moulds shell RCCB, including substrate, fixed plate,
Gripper shoe, rotating shaft, the second pedestal, zero formula transformer, lock-screw, the first pedestal, operational module, spring, protective cover and fastening
Screw；Described substrate side is provided with fixed plate；Described fixed plate is L-shaped；The side of described fixed plate is provided with and sets with substrate-parallel
The gripper shoe put；Described substrate is provided with rotating shaft；Described substrate is provided with the second pedestal that can rotate around the axis；Described second base
Zero formula transformer it is provided with in Zuo；Described base plate bottom is provided with counterbore；It is provided with lock-screw in described counterbore；Described second pedestal leads to
Cross the lock-screw through counterbore to be fixedly linked with substrate；Described gripper shoe is provided with the first pedestal；In described first pedestal admittedly
It is provided with operational module；Described fixed plate lower end is provided with spring；Described lower spring end is provided with protective cover；Described protective cover lower end is passed through
Two trip bolts are fixedly linked with substrate.
Preferably, described protective cover is U-shaped.
Preferably, both sides, described protective cover lower end are provided with the first locating piece；On described substrate corresponding with the first locating piece
Position is provided with the second locating piece；Described trip bolt sequentially passes through the first locating piece and the second locating piece by protective cover lower end and base
Plate is fixedly linked.
Preferably, it is respectively equipped with inlet wire binding post and outlet binding post in described operational module and zero formula transformer.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
The present invention program moulds shell RCCB, its compact overall structure, by the operational module in chopper and zero formula mutual inductance
Device is independently separated, thus avoids causing the whole of product to scrap due to the damage of zero formula transformer, reduces life
Produce cost, bring favorable influence to the production development of enterprise, there is higher practical value.

Detailed description of the invention
Below in conjunction with the accompanying drawings and specific embodiment the present invention is described in further detail.
One of the present invention as shown in accompanying drawing 1-4 moulds shell RCCB, including substrate 1, fixed plate 2, supports
Plate 3, rotating shaft the 4, second pedestal 5, zero formula transformer 6, lock-screw the 7, first pedestal 8, operational module 9, spring 10, protective cover 11
With trip bolt 12；Described substrate 1 side is provided with fixed plate 2；Described fixed plate 2 is L-shaped；The side of described fixed plate 2 is provided with
The gripper shoe 3 be arrangeding in parallel with substrate 1；Described substrate 1 is provided with rotating shaft 4；Described substrate 1 be provided with can around the shaft 4 rotate
Second pedestal 5；It is provided with zero formula transformer 6 in described second pedestal 5；It is provided with counterbore bottom described substrate 1；It is provided with in described counterbore
Lock-screw 7；Described second pedestal 5 is fixedly linked with substrate 1 by the lock-screw 7 through counterbore；Set in described gripper shoe 3
There is the first pedestal 8；It is installed with operational module 9 in described first pedestal 8；Described fixed plate 2 lower end is provided with spring 10；Described spring
10 lower ends are provided with protective cover 11；Described protective cover 11 lower end is fixedly linked with substrate by two trip bolts 12；Described protection
Cover 11 U-shaped；Both sides, described protective cover 11 lower end are provided with the first locating piece 13；On described substrate 1 corresponding to the first locating piece 13
Position be provided with the second locating piece 14；Described trip bolt 12 sequentially passes through the first locating piece 13 and the second locating piece 14 will protection
Cover 11 lower ends to be fixedly linked with substrate 1；It is respectively equipped with inlet wire binding post in described operational module 9 and zero formula transformer 6 and goes out
Line binding post.
When real work, when find zero formula transformer be damaged need change time, first trip bolt is unclamped, from
And protective cover and base plate bottom are separated from each other, then the most firmly protective cover is up pushed away, due to protective cover and fixed plate
Between be provided with spring, so due to the effect of spring force so that between protective cover and fixed plate compress, thus by second pedestal dew
Out, then unclamp the lock-screw in substrate counterbore so that the second pedestal separates with substrate, and then utilize rotating shaft, by
Two pedestals spin out in substrate, thus the most easily zero formula transformer can be replaced or be keeped in repair, it is to avoid by
Scrapping of whole product is caused in the single damage of zero formula transformer.
The present invention moulds shell RCCB, its compact overall structure, by the operational module in chopper and zero formula mutual inductance
Device is independently separated, thus avoids causing the whole of product to scrap due to the loss of zero formula transformer, reduces life
Produce cost, bring favorable influence to the production development of enterprise, there is higher practical value.
Below it is only the concrete exemplary applications of the present invention, protection scope of the present invention is not constituted any limitation.All employings
The technical scheme that equivalents or equivalence are replaced and formed, within the scope of all falling within rights protection of the present invention.
