Embodiment
As shown in Figure 2, the circuit of single-stage electromagnetic interface filter of the present invention has two inputs, two outputs and an earth terminal, and during use, shell should connect the earth.Circuit comprises common mode choke (also known as common mode inductance) L, filter capacitor C1 ~ C4.L is inoperative to series mode interference, but when there is common mode disturbances, because the flow direction of two coils is identical, after overcoupling, total inductance amount increases rapidly, therefore presents very large induction reactance to common-mode signal, makes it to not easily pass through, therefore is called common mode choke.Its two coils respectively around on the ferrite bead of low-loss, high permeability, when have electric current by time, the magnetic field on two coils will be strengthened mutually.The inductance value of L is relevant with the rated current I of electromagnetic interface filter, see table 1.
The relation of table 1. inductance value scope and rated current
| Rated current I (A) | 1 | 3 | 6 | 10 | 12 | 15 |
| Inductance value range L (mH) | 8~23 | 2~4 | 0.4~0.8 | 0.2~0.3 | 0.1~0.15 | 0.0~0.08 |
When rated current is larger, the wire diameter of common mode choke also wants corresponding increase, can bear larger electric current.In addition, suitably increase inductance value, low cut characteristic can be improved.C1 and C2 adopts film capacitor, and range of capacity is roughly 0.01 Μ f ~ 0.47 μ F, is mainly used to filtering series mode interference.C3 and C4 is connected across output, and by the neutral earthing of capacitor, effectively can suppress common mode disturbances.C3 and C4 also can be connected in parallel on input, still Ceramics electric capacity, and range of capacity is 2200Pf ~ 0.1 μ F.For reducing leakage current, capacitance must not more than 0.1 μ F, and capacitor midpoint should be connected with the earth.The withstand voltage of C1 ~ C4 is 630VDC or 250VAC.
L1, L2 of two-stage combined type electromagnetic interface filter, C3 and C4 be used for filtering common mode interference, C1, C2 and C5 filtering series mode interference.R1 is bleeder resistance, the charge discharging resisting of accumulation on C1, C2 and C5 can be fallen, avoid affecting filtering characteristic because of charge accumulated; The end of incoming cables of power supply can also be made after power-off not charged, and ensure the fail safe used, RF is fuse, the heater circuit of protection electro-heat equipment.Owing to adopting two-stage (also known as two joints) filtering, therefore the effect of filtering noise is better.
In the circuit of Fig. 1, L3 and C7 forms LC antiresonant circuit, and damping resistance R3 is connected in parallel on this circuit, effectively absorbs the higher harmonic component in rectifier transformer secondary loop, prevents output loop generation resonance, weakens the electromagnetic wave that electric energy turns heat energy generation.
Usually our AC supply voltage single line is connected with the earth, has the potential difference of 220V between another single line and the earth.People contacts and can produce electric shock.And the secondary of isolating transformer of the present invention is not connected with the earth, between its any two lines and the earth, there is no potential difference.People contacts any line and can not get an electric shock, so just safer.Secondly also have the output of isolating transformer to be that " open circuit " is isolated completely with input, so just the effective input to transformer (supply voltage that electrical network supplies) serves the effect of a good filtration.Thus provide pure supply voltage to power consumption equipment.
As shown in Figure 3 and Figure 4, one embodiment of the invention electric heating table comprises base 12 and table top 1, is provided with four bracing frames 5 between described base 12 and described table top 1; Heater circuit of the present invention in this electric heating table; Described table top 1 upper surface is provided with display screen; Described table top 1 lower surface is fixed with WIFI reception amplifier 3; Described table top 1 side is fixed with sound equipment 2; Four sides of described base 12 are all provided with device for massaging feet 13; In the middle part of described base 12, ultrasonic humidifier 9 is installed; The heat-generating pipe 8 of described heater circuit is arranged on support frame as described above 5, and described heat-generating pipe 8 is outside equipped with radiator-grid 6.Bracing frame 5 below described table top 1 is also fixed with heat insulation backplate 4; Wherein two bracing frames 5 are provided with Concealed socket 7, and these two support 5 top lines are parallel with a diagonal of described base 12; Described sound equipment 2 is fixed on the drift angle place of described table top 1; The side of described table top 1 is provided with usb 15.
Display screen super low-power consumption of the present invention: work≤750mW; Standby≤250mW, can saves energy.Cost is low, strong adaptability, not by the interference of electric current, voltage, electrostatic, can adapt to various environment.
Ultrasonic humidifier has sterilizing effect, this heating system from human body proximity of electric heating table, can absorb the moisture on people surface in a large number, cause dry skin and people is often experienced thirsty, greatly improve this situation after installing humidifier.Hot humidification is used in winter, can cold humidification in summer, can accomplish cool in summer and warm in winter.
