Description
Technical field
The utility model relates to low voltage electrical apparatus technology field, especially a kind of rectangle electric leakage and arc fault detection mutual inductance
Device.
Background technique
What is used on existing market is used alone as two devices about arc-detection mutual inductor and creepage mutual inductor,
Not only increased costs in this way, also increase breaker volume, are unfavorable for the detection of breaker, therefore the mutual inductance that will leak electricity can be considered
Device and the production of arc-detection mutual inductor are integral.In addition, existing creepage mutual inductor is all to install fixed, installation by bottom plate
Direction cannot become, and also add somewhat to the volume of breaker.
Utility model content
Technical problem to be solved by the utility model is: overcome the deficiencies in the existing technology, provide a kind of rectangle electric leakage and
Arc fault detection mutual inductor.
The technical scheme adopted by the utility model to solve the technical problem is as follows: a kind of rectangle electric leakage and arc fault detection
With mutual inductor, mutual inductor ontology including shell and in shell, the mutual inductor ontology include iron based nano crystal magnetic core,
Coil, lead-out wire and transformer housing are coated with insulated paint on the magnetic core, and coil, the both ends point of coil are arranged with outside magnetic core
It is not connect with a lead-out wire, the magnetic core for being wound with coil is arranged in transformer housing, and by epoxide-resin glue hydropexis;It is described
Shell has the central through hole of rectangle, and the installation for stretching out shell is connected on the shell of the central through hole middle upper part
Plate is vertically installed with screw rod on the mounting plate, and the lower end of screw rod is fixed with elastic pressing disc.
It further limits, the top of the shell has opening, is provided with cover board in opening, offers on the cover board
The outlet of lead-out wire.
It further limits, the cover board is equipped with housing, and four sides of the housing offer through-hole.
The beneficial effects of the utility model are: a magnetic core of the utility model can realize detection of electrical leakage and electricity simultaneously
Arc detection, coil method saves half, and detection of electrical leakage range becomes larger;All directions can be suitble to install, adapt to complete cabinet
Installation in body.
Detailed description of the invention
The present invention will be further described with embodiment with reference to the accompanying drawing.

Specific embodiment
The utility model is further described presently in connection with attached drawing.These attached drawings are simplified schematic diagram only to show
Meaning mode illustrates the basic structure of the utility model, therefore it only shows composition related with the utility model.
As shown in Figure 1, Figure 2 and Figure 3, a kind of rectangle electric leakage of the present embodiment and arc fault detection mutual inductor, including
Shell 1 and the mutual inductor ontology in shell 1, mutual inductor ontology include the magnetic core 2, coil 3, lead-out wire 4 of iron based nano crystal
With transformer housing 5, it is coated with insulated paint on magnetic core 2, is arranged with coil 3 outside magnetic core 2, the both ends of coil 3 are drawn with one respectively
Outlet 6 connects, and the setting of magnetic core 2 for being wound with coil 3 is fixed in transformer housing 5, and by epoxy resin glue 6;Shell 1 has
The central through hole 1-1 of rectangle is connected with the mounting plate 7 for stretching out shell 1, peace on the shell 1 of central through hole 1-1 middle upper part
Screw rod 8 is vertically installed in loading board 7, the lower end of screw rod 8 is fixed with elastic pressing disc 9.
In embodiment itself, the top of shell 1 has opening, is provided with cover board 10 in opening, offers on cover board 10
The outlet of lead-out wire 6.Cover board 10 is equipped with housing 11, and four sides of housing 11 offer through-hole 12.
Two toroidal cores are originally needed, one is detection electric leakage, and one is detection electric arc, as long as one magnetic of the present embodiment
Ring can be achieved with two above function, so coil method saving is original half, and improve the detection of electrical leakage model of product
It encloses, the detection of 100mA electric leakage is changed to by original 30mA.In order to meet the structure of different breakers, the present embodiment passes through activity
The mounting plate and screw rod 8, the elastic pressing disc 9 that are connected on shell 1 can realize the installation of all directions.
Above embodiment is only to illustrate the technical ideas and features of the present invention, and its object is to allow be familiar with this skill
The personage of art can understand the content of the utility model and be implemented, and the protection model of the utility model can not be limited with this
It encloses, all equivalent change or modifications according to made by the spirit of the present invention essence should all cover the protection model in the utility model
In enclosing.
