Earth leakage protective moulded case circuit breaker also has creepage protection function, realizes earth leakage protective by the effect of ZCT, when
During circuit electric leakage, ZCT sends signal transmission to electrical apparatus release, promotes tripping mechanism to carry out threading off protecting by electrical apparatus release
The security performance of shield equipment.
But find in actual use, the ZCT in existing earth leakage protective moulded case circuit breaker and other portions
The installation of part is respectively positioned on same base, so when ZCT outlet problem, can lead to whole product rejection, thus
The raising leading to production cost is it is impossible to meet Production requirement and the large-scale production of enterprise.
Utility model content
This utility model purpose is to overcome the deficiencies in the prior art to provide a kind of structure simple, working as ZCT
During damage, an earth leakage protective moulded case circuit breaker that ZCT need to be changed.
For reaching above-mentioned purpose, the technical solution adopted in the utility model is：A kind of earth leakage protective moulded case circuit breaker,
Including the first pedestal, operating-controlling mechanism, location-plate, rotary shaft, the second pedestal, locking nut, ZCT, lock-screw, consolidate
Rationed marketing, protective cover and clamping screw；It is provided with operating-controlling mechanism in described first pedestal；Described first pedestal side is provided with location-plate；
On described first pedestal, one end both sides near location-plate are provided with rotary shaft；Described second pedestal passes through rotary shaft and locking nut
Rotatable it is connected with the first pedestal；It is provided with ZCT in described second pedestal；Locking is passed through in described second pedestal upper end
Screw is connected with location-plate；Described first pedestal both sides further respectively have screwed hole and steady pin；Described protective cover two ends are respectively
It is provided with hole clipping；Described protective cover one end is fastened on steady pin by hole clipping, and the other end is via sequentially passing through screwed hole and hole clipping
Clamping screw with first pedestal fastening be connected.
Preferably, it is respectively equipped with inlet wire binding post in described first pedestal and the second pedestal and binding post occurs.
Preferably, described protective cover be shaped as rectangle.
Due to the utilization of technique scheme, this utility model compared with prior art has following advantages：
The earth leakage protective moulded case circuit breaker of this utility model scheme, its structure is simple, easy to operate, can be very convenient
The ZCT in the operating-controlling mechanism in the first pedestal and the second pedestal is carried out blocking protection, simultaneously ZCT damage
Bad when, only the second pedestal need to be taken out from the first pedestal and be changed, so avoid the waste of material, reduce production
Cost, meets the demand of enterprise, has higher practicality.

Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
Described in the utility model a kind of earth leakage protective moulded case circuit breaker as illustrated in the accompanying drawings from 1 to 3, including the first base
Seat 1, operating-controlling mechanism 2, location-plate 3, rotary shaft 4, the second pedestal 5, locking nut 6, ZCT 7, lock-screw 8, fixation
Pin 9, protective cover 12 and clamping screw 13；It is provided with operating-controlling mechanism 2 in described first pedestal 1；Described first pedestal 1 side is provided with fixed
Position plate 3；On described first pedestal 1, one end both sides near location-plate 3 are provided with rotary shaft 4；Described second pedestal 5 passes through rotary shaft
4 rotatable with locking nut 6 are connected with the first pedestal 1；It is provided with ZCT 6 in described second pedestal 5；Described second base
Seat 5 upper ends are connected with location-plate 3 by lock-screw 8；Described first pedestal 1 both sides further respectively have screwed hole 10 and steady pin
9；Described protective cover 12 is respectively arranged at two ends with hole clipping 11；Described protective cover 12 one end is fastened on steady pin 9 by hole clipping 11, separately
One end is connected with the first pedestal 1 fastening with the clamping screw 13 of hole clipping 11 via sequentially passing through screwed hole 10；Described first pedestal 1
Be respectively equipped with inlet wire binding post and binding post occurs in the second pedestal 5；Described protective cover 12 be shaped as rectangle.
In actual making, the operating-controlling mechanism in the first pedestal is connected with ZCT, the operating-controlling mechanism in the first pedestal
Protected by protective cover, the ZCT in the second pedestal carries out blocking protection by location-plate, when discovery zero sequence is mutual
When sensor damages, manually lock-screw is unloaded down first, then locking nut is unloaded down from rotary shaft, thus permissible
Second pedestal is separated from the first pedestal, then carries out changing by ZCT, so avoid zero sequence
During transformer loss, whole product just is scrapped.
Further, wherein protective cover plays the effect of protection to operating-controlling mechanism, it is to avoid have debris to enter into operating-controlling mechanism
In, thus causing to operating mechanism to damage；When needing to open protective cover, by clamping screw from the screwed hole of the first pedestal
Screw out, then protective cover is taken out from steady pin, practicality easy for installation.
Earth leakage protective moulded case circuit breaker of the present utility model, its structure is simple, easy to operate, can easily will very much
ZCT in operating-controlling mechanism in first pedestal and the second pedestal carries out blocking protection, and ZCT damages simultaneously
When, only the second pedestal need to be taken out from the first pedestal and be changed, so avoid the waste of material, reduce and produce into
This, meet the demand of enterprise, have higher practicality.
The above is only concrete application example of the present utility model, any limit is not constituted to protection domain of the present utility model
