Description
Technical field
The utility model relates to a kind of anti-electric wall, relates in particular to the anti-electric wall of a kind of electric water heater.
Background technology
Current electric water heater electricity-preventing wall; typically using leakage switch or earth detector detects and protects electric leakage; because this class leakage switch or earth detector self have certain service life; and cost is high; also there is the possibility of damaging, electric shock accidents just easily occurs after damaging.
Regulation according to BG13955-92 " earth leakage protective device installation and operation ", is controlled at electric heater leakage current in 10mA, can guarantee user's safety.When the direct short circuit of 220V power supply that electric leakage occurs or use is in heated water, the dielectric resistance R=220V/10mA=22*103 Ω of running water.
Because the electricalresistivityρ of running water equals 1300 Ω ● cm, if get the length of insulation water pipe, be L, in insulation water pipe, pore radius is r, and the dielectric resistance of water is R, and resistivity of water is ρ, that is:
L=R●S/ρ=R●∏r
2/ρ=22*10
3*3.14/1300≈53?r
2
So, when the length of insulation water pipe be greater than 28 times of diameter of bore r square, i.e. L > 53 r
2, just can guarantee to do anticreep isolation with the water resistance of running water.
