This has more strict requirements, especially for Leakage Current problem, it is necessary to cause enough attention.
For the Electric radiant Heating Film of electricity floor heating, when overlying or under attach the structure sheaf of certain electric conductivity when (such as：Metal mesh or
Metal film, cement sand bed, pea gravel concrete layer etc.), form capacitance structure.It is powered, will be produced in the structure sheaf to Electric radiant Heating Film
Certain sensing electric current, is known as leakage current.Leakage current covers the dielectricity of material with Electric radiant Heating Film product type, Electric radiant Heating Film up and down
Energy, input voltage are related with frequency, and cumulative effect is added to electric heating membrane area.Leakage current pair caused by electric heat membrane heating
Human body is harmless, but electric safety of building requirement in China's is 30mA in the action current of the earth leakage protective device of 220V, 50Hz, and on
Leakage current is stated also usually to work as Electric radiant Heating Film area of mating formation by earth leakage protective device and exceed certain area, such as：At 20 square metres,
Leakage current will exceed 30mA, it is impossible to ensure that Heating System of Electric radiant Heating Film works normally.
Utility model content
In view of the above problems, the purpose of this utility model is to provide one kind to shield leakage current Electric radiant Heating Film, it is intended to solves
Technical problem of the existing Electric radiant Heating Film there are leakage current security risk.
The utility model adopts the following technical solution：
The shielding leakage current Electric radiant Heating Film includes heating layer, and the heating layer includes cathode current-carrying bar, anode current-carrying bar
And fever carbon film of the connection between positive and negative anodes current-carrying bar, the fever carbon film top is also evenly distributed with heat-conducting glue, described
Electric radiant Heating Film further includes metallic shield net, and the metallic shield net left and right ends bend downward to form bending part, the heating layer position
In in the metallic shield net, and positive and negative anodes current-carrying bar is respectively positioned in the bending part of corresponding side, the heating layer and metallic shield
Insulation rubber is filled between net, the upper strata of the metallic shield net and bending lower floor are both provided with ambroin film, described negative
Conducting bracket is installed between pole current-carrying bar and bending part, insulating support is installed between the cathode current-carrying bar and bending part.
Further, it is additionally provided with reflectance coating between the end of two bending parts.
The beneficial effects of the utility model are：The utility model sets metallic shield net, metallic shield net in Electric radiant Heating Film
With two bending parts, positive and negative anodes current-carrying bar is located in bending part, and conductive branch is installed between anode current-carrying bar and bending part
Frame, installs insulating support between cathode current-carrying bar and bending part, such metallic shield net is led in Electric radiant Heating Film with anode current-carrying bar
Logical, metallic shield Netcom crosses insulating support and isolates with cathode current-carrying bar, and the Electric radiant Heating Film leakage current to be formed that is powered can pass through anode
Current-carrying bar is back to power cathode, avoids incoming ground human body, ensures that Electric radiant Heating Film is safe to use；And and metallic shield net with
Fever carbon film is isolated by insulation rubber, is added the spacing of metallic shield net and the carbon film that generates heat, can further be subtracted leakage current,
And metallic shield net will not be contacted with fever carbon film so that product uses safer；In addition, heat conduction is set above fever carbon film
Glue so that electric heating film for heating is more uniformly distributed.
