Description
Technical field
This utility model relates to a kind of big current leakage circuit breaker.
Background technology
Rated current is the RCCB of 40A, and wiring board is provided with transformer, it is desirable to promote load current value, then
Need to change thicker big ampere wires, but only transformer worn by two wires, and the leakage of existing more high rated current value
The volume of electrical circuit breakers is the biggest, it is impossible to meet the use demand of client.
Summary of the invention
The purpose of this utility model is to overcome the defect of prior art, it is provided that a kind of volume is less, more reasonable structure, volume
Determine the higher big current leakage circuit breaker of current value.
For achieving the above object, this utility model uses the big current leakage circuit breaker of such a, including housing, housing bag
Include upper cover, middle cover, lower cover, be provided with magnetictrip, static contact, patch panel in housing and be connected with magnetictrip and be connected to phase
The wire of line side patch panel and transformer, wherein magnetictrip includes solenoid conductor and extends with solenoid conductor
Formed shaped portion, shaped portion from phase line side through middle cover enter neutral side, phase line side joint line plate with extension,
Extension enters neutral side, the top, extension of patch panel and the shaped portion of magnetictrip from phase line side through middle cover
Top is connected with each other with the wire through ZCT.
Such setting, optimizes the structure of RCCB, and solenoid conductor is through middle cover to neutral side so that lead
Line wiring is more convenient.
This utility model is further arranged to, and static contact extends near transformer side and forms elongated end, and elongated end is positioned at
Part concave downward inside transformer forms groove, and elongated end is connected with the patch panel of neutral side after transformer.
Such setting, static contact extend near transformer side formed elongated end replace originally through the two of transformer
In bar wire one, the groove on elongated end can make another wire have enough spaces through transformer, it is achieved that not
In the case of variation RCCB volume, improve the load current value of RCCB so that big current leakage circuit breaker
Disclosure satisfy that the use demand of user.

Detailed description of the invention
As Figure 1-4, a kind of big current leakage circuit breaker, including housing, housing includes upper cover, middle cover, lower cover 7, shell
Internal magnetictrip 1, static contact 2, the patch panel 3 of being provided with is connected with magnetictrip 1 and is connected to leading of phase line side patch panel 3
Line 4 and transformer 5, wherein magnetictrip 1 includes solenoid conductor 11 and extends formation with solenoid conductor 12
Shaped portion 12, shaped portion 12 enters neutral side from phase line side through middle cover 7, phase line side patch panel 3 with extension 31,
Extension 31 is entered 7 from phase line side through middle cover and is entered neutral side, the top, extension 31 of patch panel 3 and magnetictrip 1
Shaped portion 12 top is connected with each other with the wire 4 through ZCT 5.
Such setting, optimizes the structure of RCCB, the moulding section 12 of solenoid conductor 11 and phase line side
The extension 31 of patch panel 3 is through middle cover 7 to neutral side so that wire 4 wiring is more convenient.
The end of the close transformer side of static contact 2 is recessed and horizontal expansion forms elongated end 21, and elongated end 21 is positioned at
Part concave downward inside transformer 5 forms groove 22, and elongated end 21 is through patch panel 3 phase with neutral side after transformer 5
Even.
Such setting, static contact 2 extend near transformer side formed elongated end 21 replace originally through transformer 5
Two wires 4 in one, the groove 22 on elongated end 21 can make another wire 4 have enough spaces through transformer 5,
Achieve in the case of not changing RCCB volume, improve the load current value of RCCB so that big electric current
RCCB disclosure satisfy that the use demand of user.
