It is more.And electrothermal heating technology has also more and more been applied in people’s lives, wherein Electric radiant Heating Film is more common one
Kind of electric calorifie installation, Electric radiant Heating Film are the polyester film products that can be generated heat after a kind of energization, and skin-material is polyester film.With skill
The solution of the problems such as art, material cost and fever carbon slurry technology, the application range of Electric radiant Heating Film is also increasingly wider, from finishing, electricity
Son, medical treatment have large-scale application to space flight, agricultural etc..However, existing Electric radiant Heating Film product is in process of deployment, due to material
The factors such as the dielectric properties of material, often when Electric radiant Heating Film is powered, there are certain conductions for the structure sheaf covered above and below Electric radiant Heating Film
Performance, and form capacitance structure, also known as leakage current.
What the leakage current that Electric radiant Heating Film generates when in use endanger human body without, but the electric safety of building in China is wanted
The general action current of the earth leakage protective device in civil buildings asked is 30MA, and is more than certain when electric heating membrane type heating is laid with area
When area, leakage current will be more than 30MA, switch for leakage protector can be promoted to act in this way, so that Heating System of Electric radiant Heating Film
It has no idea to work normally.
The method for solving problem above is mainly method one, by increasing the number of earth leakage protective device, each electric leakage is made to protect
The Electric radiant Heating Film leakage current that works is no more than the action current of earth leakage protective device under shield device, often building 100 square metres of a family
4-5 earth leakage protective device is set in building, use is highly inconvenient.Method two is laid with certain thickness on Electric radiant Heating Film
Insulating materials, to reduce and stop that the generation of leakage current, this method significantly increase the installation cost of Electric radiant Heating Film.Method
Three, make dedicated leakage current using aluminium foil either metal mesh and in the levels of aluminium foil or metal mesh setting insulation system
Gauze screen, to achieve the purpose that absorption and shielding Electric radiant Heating Film leakage current.
The prior art is stated at least to have the following disadvantages：
Method one increases system cost, while reducing the safety of integral room circuit.So that earth leakage protective device is from very
Good diagnosis electric fault.
Method two, increase installation cost, while be laid with insulating materials should consider insulating properties consider again it is heat-resisting and heat dissipation
Property, and easily appearance protection is improper to cause earth leakage protective device action under moisture conditions.
Method three, make it is dedicated absorption and shielding leakage current gauze screen, although this method can solve Electric radiant Heating Film because
The installation method of trip phenomenon caused by leakage current problem, larger cost of manufacture and complexity all significantly increases system
Risk and the safety used.
