Abstract
The present invention relates to a kind of quadrupole moulded case circuit breaker with creepage protection function.It includes the middle cover on the body of chopper and the pedestal of magnetic thermal trip module, and the position that lid is the most corresponding with N in the body has a groove, installs chopper creepage protection function in a groove and controls electron plate assembly and power module.On the alternate next door of the side connected with body on the pedestal of magnetic thermal protection module and sidewall, and it is around around the joint cover that magnetic thermal trip is connected with body, has and creepage mutual inductor loading can be fixed on the groove on pyromagnetic protection modular substrate.Due to the fact that so that each several part parts controlled including electron plate assembly and creepage mutual inductor include creepage protection function all can put into magnetothermal circuit breaker internal; meet basic two section protection and earth leakage protective demand the most simultaneously; and accomplished further to make the quadrupole moulded case circuit breaker with creepage protection function integrated, miniaturization.
Description
Technical field
The invention belongs to a kind of moulded case circuit breaker, particularly relate to a kind of there is the quadrupole of creepage protection function to mould
Material casing type circuit breaker.
Background technology
Along with the development of society, the requirement for low-voltage circuit breaker is more and more higher, and the function of its protection module is complete
Face and volume little be inevitable development trend.Protection module at currently known magnetothermal moulded case circuit breaker is only disconnected
The basic functions such as two sections of protections are met in the device of road, when needs add earth leakage protective, can only at the outlet terminals of chopper again
Connecting a leakage protection module, thus the size of product can strengthen, chopper can seem the heaviest.
Summary of the invention
The present invention solves technical problem present in known technology and provide a kind of outlet that need not at chopper to connect
Line end is connected the quadrupole moulded case circuit breaker with creepage protection function of a leakage protection module again.
The present invention solves that technical problem is adopted the technical scheme that present in known technology: it includes described disconnected
Middle cover on the body of road device and the pedestal of magnetic thermal trip module, cover the position the most corresponding with N in described body
There is a groove, described groove is provided with two power modules and chopper earth leakage protective that creepage protection function controls
Function controls electron plate assembly；Two described power modules are fixed in its horizontal direction by the several dividing plates in described groove
Position, and described creepage protection function controls electron plate, the top of two cylinders being connected on described bottom portion of groove use
Self-tapping screw is fixed, and so the most also secures the position of said two power module；At described magnetic
On the alternate next door of the side that the pedestal of thermal protection module connects with body and sidewall thereof, and it is around magnetic thermal trip and basis
Around the joint cover that body connects, have and creepage mutual inductor loading can be fixed on the groove on pyromagnetic protection modular substrate.
The present invention has the advantage that with good effect: in order to, on the premise of not changing chopper actual size, leak
Electric protection function joins in the middle of the chopper that script space is the narrowest and together with original two sections of basic defencive functions
The three-stage protection function that composition function is powerful.And need not as before, when will reach this three-stage protection function, it is necessary at chopper
Connect again at outside leading-out terminal a leakage protection module.The present invention is to the middle cover of breaker body and magnetic thermal trip module
The construction profile of pedestal has done meticulous appropriate design, and the reasonable cloth when designing creepage protection function control electron plate assembly
Line, and then reduce the volume of electron plate.By the Creative Design in terms of these so that include creepage protection function control
Electron plate assembly and creepage mutual inductor all can put into magnetothermal circuit breaker internal at interior each several part parts, and creepage mutual inductor is leakage
Electric protection function controls electron plate assembly provides the signal of telecommunication.This design meets basic two section protection the most simultaneously and electric leakage is protected
The demand protected, and accomplished integrated further, miniaturization, it is ensured that when needs add creepage protection function, chopper
Volume will not strengthen, and then the miniaturization for integrated system provides help.

Detailed description of the invention
For present disclosure, feature and effect can be further appreciated that, hereby enumerate following example, and coordinate accompanying drawing detailed
It is described as follows:
As shown in Figure 1, 2, 3: on the pedestal 2 of magnetic thermal trip module, in its side connected with body separately
Have groove 6 on wall and sidewall, creepage mutual inductor 3 is inserted in groove 6.It 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 in the middle of creepage mutual inductor.
As shown in FIG. 4,5,6, 7, creepage protection function controls electron plate assembly 9 in wiring, the side such as selection of electronic component
Under the effort in face, by its overall dimensions than the size reduction of the electron plate assembly realizing identical function in the past；In level Four open circuit
The position, N pole fluted 12 corresponded on the middle cover 7 of device body, dividing plate 14 is separated out in groove 12 and is suitable for fixed power source mould
Two grooves 13 of block 11；In groove 12, it is designed for fixing creepage protection function controls two pillar type columns 10 of electron plate 9；
As it is shown in figure 5, first power module 11 is arranged in groove 13, more as shown in Figure 4 creepage protection function is controlled electron plate 9 uses
The top of two pillar type columns 10 that two tapping screws 8 are fixed in groove 12.Creepage protection function controls electron plate assembly 9 He
Power module 11 is fixed in body middle cover groove 12 as shown in Figure 4.As shown in Figure 8, power module 11 is fixed on by middle cover
7, in the space that creepage protection function control electron plate 9 and dividing plate 14 collectively constitute；As shown in Figure 4, creepage protection function controls
Electron plate assembly 9 is fixed on the top of pillar type column 10.
