Abstract

The utility model relates to a quadrupole moulded case circuit -breaker. Its zhong gai on the body of circuit breaker and base of magnetism thermal overload release module has a recess, installation circuit breaker electric leakage protection function control electron plate subassembly and power module in the recess on lid and the N extremely corresponding position in the body. On the alternate next door and lateral wall of one side of meeting with the body on the base of the hot protective film piece of magnetism, and around the hitch plate of magnetism thermal overload release and this body coupling around, have and to pack into and fix the recess on thermomagnetic protective film block base seat leaking electric transformer. The utility model discloses owing to make inside magnetism hot type circuit breaker is put into with each the subunit homoenergetic including leaking electric transformer to electric leakage protection function control electron plate subassembly, not only satisfied two sections protections of essential and earth leakage protection's demand simultaneously, accomplished further moreover that the quadrupole moulded case circuit -breaker that the messenger has an electric leakage protection function integrates the miniaturization.

Description

Quadrupole moulded case circuit breaker

Technical field

This utility model belongs to a kind of moulded case circuit breaker, more particularly to a kind of quadrupole plastic casing type open circuit Device.

Background technology

With social continuous development, for the requirement also more and more higher of low-voltage circuit breaker, the function of its protection module is complete Face and small volume are inevitable development trend.Only it is 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, when needing to add earth leakage protective, can only in the outlet terminals of chopper again One leakage protection module of series connection, thus the size of product can increase, chopper can seem very heavy.

Content of the invention

This utility model provides and a kind of does not need going out in chopper for solving technical problem present in known technology Mouthful terminals are connected the quadrupole moulded case circuit breaker with creepage protection function of a leakage protection module again.

This utility model is adopted the technical scheme that by solving technical problem present in known technology：It is included State the pedestal of middle cover on the body of chopper and magnetic thermal trip module, cover extremely corresponding with N in described body There is a groove position, is provided with two power modules and the chopper electric leakage of creepage protection function control in described groove Defencive function controls electronics board component；Two described power modules fix its horizontal direction by the several dividing plates in described groove On position, and described creepage protection function controls electron plate, by the top of two cylinders being connected on described bottom portion of groove Portion's self-tapping screw gives to fix, and so also secures the position of described two power modules in vertical direction；Described The alternate next door of side that connects with body of the pedestal of magnetic thermal protection module and its side wall on, and be around magnetic thermal trip Around the joint cover being connected with body, have and creepage mutual inductor can be loaded the groove being fixed on pyromagnetic protection module pedestal.

This utility model has the advantages and positive effects that：In order on the premise of not changing chopper actual size, By creepage protection function be added in the middle of the just very narrow chopper in script space with original two sections of basic defencive functions The powerful three-stage protection function of composition function together.And without as before, reaching during this three-stage protection function it is necessary to disconnected Connect again at the outside leading-out terminal of road device a leakage protection module.This utility model is threaded off to the middle cover of breaker body and magnetic heat The construction profile of the pedestal of device module has done meticulous appropriate design, and controls electronics board component in design creepage protection function When reasonable line arrangement, and then reduce the volume of electron plate.By the Creative Design of these aspects so that including earth leakage protective Function control electronics board component and creepage mutual inductor all can put into magnetothermal circuit breaker internal in interior each several part part, and electric leakage is mutually Sensor controls electronics board component to provide the signal of telecommunication for creepage protection function.This design not only meets basic two section protection simultaneously With earth leakage protective demand, and accomplished integrated further, miniaturization it is ensured that needing plus during creepage protection function, The volume of chopper will not increase, and then provides help for the miniaturization of integrated system.

Specific embodiment

For content of the invention of the present utility model, feature and effect can be further appreciated that, hereby enumerate following examples, and coordinate Accompanying drawing describes in detail as follows：

As shown in Figure 1, 2, 3：On the pedestal 2 of magnetic thermal trip module, the side connecting with body at it is separately Have groove 6 on wall and side wall, creepage mutual inductor 3 is inserted in 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 in the middle of creepage mutual inductor.

As shown in FIG. 4,5,6, 7, creepage protection function controls electronics board component 9 in the side such as wiring, selection of electronic component Under the effort in face, by its overall dimensions than the electronics board component realizing identical function in the past size reduction；In quadrupole open circuit Fluted 12 at the N pole position corresponding 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；It is designed for two pillar type columns 10 that fixing creepage protection function controls electron plate 9 in groove 12； As 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 to use Two tapping screws 8 are fixed on the top of two pillar type columns 10 in groove 12.Creepage protection function controls electronics board component 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 7th, creepage protection function controls in the space that electron plate 9 and dividing plate 14 collectively constitute；As shown in figure 4, creepage protection function controls Electronics board component 9 is fixed on the top of pillar type column 10.
