The present invention relates to a kind of moulded case circuit breakers with one-phase ground protection function.It includes the pedestal of the middle cover and magnetic thermal trip module on the ontology of breaker, and two grooves of size are separated out in the attachment recess on the right side of middle cover, installs breaker one-phase ground protection function control electron plate and power module respectively.On the alternate next door of the side to connect with ontology on the pedestal of magnetic thermal protection module and side wall, and surrounded around the joint cover that magnetic thermal trip is connect with ontology, it is fluted single-phase earthing mutual inductor to be packed into and be fixed on pyromagnetic protection module pedestal.The present invention by each section component including one-phase ground protection function control electron plate and single-phase earthing mutual inductor due to can be put into magnetothermal circuit breaker internal; not only simultaneously meet basic magnetic, heat two sections protection and one-phase ground protection demand; and further accomplished to make to have the moulded case circuit breaker of ground protection function integrated, it minimizes.
Description
Technical field
The invention belongs to a kind of moulded case circuit breakers, more particularly to a kind of modeling with one-phase ground protection function
Expect casing type circuit breaker.
Background technology
With the continuous development of society, also higher and higher for the requirement of low-voltage circuit breaker, the function of protection module is complete
Face and it is small be inevitable development trend.It is only disconnected in the protection module of currently known magnetothermal moulded case circuit breaker
The basic functions such as two sections of protections are met in the device of road, it, can only going out in breaker when needing to increase one-phase ground protection function
Mouthful terminals are connected a ground protection module again, can be increased to the size of product, breaker can seem very heavy.
Invention content
The present invention for solve known technology present in technical problem provide one kind in moulded case circuit breaker i.e.
With two sections of basic defencive functions also plastic shell with one-phase ground protection function with one-phase ground protection function
Formula breaker.
The present invention is adopted the technical scheme that solve technical problem present in known technology：It includes described disconnected
The pedestal of middle cover and magnetic thermal trip module on the ontology of road device, and with the side that is connected with the magnetic thermal trip module
It is used to install the attachment recess of attachment for the right side of the middle cover on the breaker body of lower end, it is characterized in that：It will be described
Attachment recess is separated out small one and large one two grooves, and one-phase ground protection function control is fixedly mounted in the little groove and uses
Power module, in the big groove be fixedly mounted one-phase ground protection function control electronics plate；In the magnetic heat
On the alternate next door for the side that the pedestal of protection module connects with the ontology and its side wall, and it is around the magnetic thermal tripping
Around the joint cover that device is connect with the ontology, pyromagnetic protection module pedestal can be fixed on by the loading of single-phase earthing mutual inductor by having
On groove, and the single-phase earthing mutual inductor that is fixedly mounted in groove on the pyromagnetic protection module pedestal.
The present invention can also adopt the following technical scheme that：
In the little groove be fixedly mounted one-phase ground protection function control power module with it is described
Four walls of little groove are to be fixedly clamped, i.e., four wall of little groove and power module are tight fit.
The breaker one-phase ground protection function control electronics plate is to collectively constitute electricity by upper and lower two pieces of electron plates
Daughter board component is combined by terminal grafting between two pieces of electron plates；Bottom in the big groove has one
With the female cylinder of edge, the bottom of the electronics board group is positioned on the top surface of the cylinder, and is screwed at a top.
The invention has the advantages and positive effects that：In order under the premise of not changing breaker original actual size,
By one-phase ground protection function be added to script space just in very narrow breaker with original two sections of basic protections
The function powerful three-stage protection function of composition function together.And do not have to as before, when reaching this three-stage protection function, it is necessary to
It connects again at circuit breaker external leading-out terminal an one-phase ground protection module.Middle cover and magnetic heat of the present invention to breaker body
The construction profile of the pedestal of buckle releaser module has done meticulous rational design, and in design one-phase ground protection function control electricity
Reasonable line arrangement when daughter board component, and then substantially reduce the volume of electron plate.Pass through the Creative Design in terms of these so that
Each section component including one-phase ground protection function control electron plate component and single-phase earthing mutual inductor can be put into magnetic
Hot type circuit breaker internal, single-phase earthing mutual inductor provide electric signal for one-phase ground protection function control electron plate component.This sets
Meter not only meets the demand of basic two sections of protections and one-phase ground protection simultaneously, and further accomplished it is integrated, it is small
Type ensure that the volume of breaker will not increase when needing to increase one-phase ground protection function, and then be integrated system
Miniaturization provides help.

Specific implementation mode
For that can further appreciate that present disclosure, feature and effect, the following examples are hereby given, and coordinates attached drawing detailed
It is described as follows：
As shown in Figure 1, 2：On the pedestal 2 of magnetic thermal trip module, the alternate next door in the side that it connects with ontology
With on side wall fluted 6, single-phase earthing mutual inductor 3 is inserted into groove 6.In addition, magnetic thermal trip 1 is placed into magnetic thermal trip
In the reserved location 5 of the pedestal 2 of module, the joint cover 4 of magnetic thermal trip 1 passes through among single-phase earthing mutual inductor 3.
As shown in Fig. 3,4,5,6,7, one-phase ground protection function control electron plate component 9 is in wiring, the choosing of electronic component
Under the effort of select etc., its overall dimensions is realized that the size of the electron plate component of identical function is substantially reduced compared with former,
And specific installation space situation is combined, two electron plates up and down are designed as, is combined, is collectively constituted by 14 grafting of terminal
