Embodiment
Socket is normally in time, the warning unit being formed by the first diode (D1), current-limiting resistance (R10), warning lamp (L1), because current-limiting resistance (R10) resistance is very large, warning lamp (L1) resistance is less, under 220V alternating current, electric current is very little, can not meet the luminous power of warning lamp (L1), so indicator light extinguishes under normal circumstances.Beat while being struck by lightning, high pressure enters circuit, and electric current is increased, and reaches the luminous power of warning lamp, and warning lamp is luminous, and the first diode (D1) of also connecting in circuit can make warning lamp (L1) constantly glimmer, and plays warning function.
Described first draws thunder unit by the first piezo-resistance (R1), the first temperature safety tube (TF1), the second piezo-resistance (R2), the second temperature safety tube (TF2), the 3rd temperature safety tube (TF3), the 3rd piezo-resistance (R3), the first discharge tube (G1), the first inductance (J1), the second inductance (J2), the 4th piezo-resistance (R4), the 4th temperature safety tube (TF4), the 5th piezo-resistance (R5), the 5th temperature safety tube (TF5), the 6th temperature safety tube (TF6), the 6th piezo-resistance (R6), the second discharge tube (G2) forms, described the first piezo-resistance (R1), the first temperature safety tube (TF1) series connection form the second branch road, described the second piezo-resistance (R2), the second temperature safety tube (TF2), the 3rd temperature safety tube (TF3), the 3rd piezo-resistance (R3) series connection form the 3rd branch road, the 4th described piezo-resistance (R4), the 4th temperature safety tube (TF4) series connection form the 4th branch road, the 5th described piezo-resistance (R5), the 5th temperature safety tube (TF5), the 6th temperature safety tube (TF6), the 6th piezo-resistance (R6) series connection form the 5th branch road, described the second discharge tube (G2) one end is connected to the 5th temperature safety tube (TF5), the 6th temperature safety tube (TF6) intermediate connection point one end ground connection, described the first discharge tube (G1) one end connects the tie point one end ground connection in the middle of the second temperature safety tube (TF2), the 3rd temperature safety tube (TF3), described the first inductance (J1) is connected on the above the second inductance (J2) of live wire (L) and is connected on zero line (N), the second described branch road, the 3rd branch circuit parallel connection are between the live wire (L) and zero line (N) in inductance left side, the 4th described branch road, the 5th branch circuit parallel connection are between the live wire (L) and zero line (N) on inductance right side.
When the maximum feature of piezo-resistance is voltage above being added in it lower than its threshold values " UN ", the electric current that flows through it is minimum, be equivalent to a valve shutting, when voltage surpasses UN, its resistance diminishes, thereby so just makes the electric current that flows through it increase sharply and the impact of other circuit is changed and not quite reduces the impact of overvoltage on follow-up sensitive circuit.Utilize this function, can suppress the frequent abnormal overvoltage occurring in circuit, protective circuit is avoided superpotential infringement.
Under normal 220V, the first piezo-resistance (R1), the second piezo-resistance (R2), the 3rd temperature guarantor the 3rd piezo-resistance (R3), the 4th piezo-resistance (R4) the 5th piezo-resistance (R5), the 5th temperature safety tube (TF5), the 6th piezo-resistance (R6) are high resistance measurements; The first temperature safety tube (TF1), the second temperature safety tube (TF2), the 3rd temperature safety tube (TF3), the 4th temperature safety tube (TF4), the, the 5th temperature safety tube (TF5), the 6th temperature safety tube (TF6)) there are million grades of above resistances, when applied voltage increases to the dielectric strength over gas, the gap of two interpolars is by discharge breakdown, by original state of insulation, be converted into conduction state, under 220V voltage, be equivalent to open circuit;
At high pressure, enter circuit, piezo-resistance resistance becomes very little, and temperature safety tube is put a little to be punctured from state of insulation and be converted into conduction state, thereby high pressure is imported to the earth, has reached the effect of protective circuit.
This draws thunder unit and has adopted two-stage composite symmetrical circuit, common mode.Differential mode is protected jointly, and residual voltage is very low, and live wire (L), zero line (N) can arbitrarily connect, and can depart from circuit safety after after piezo-resistance short circuit.
The pressure sensitive voltage reference table of piezo-resistance
Select higher a little safer, more stable, more durable of piezo-resistance, the probability ging wrong is little, but residual voltage is high, and we adopt three grades of protection head it offs.
Temperature safety tube we general that adopt is 130 ℃-135 ℃, 10A/250V, should have good thermal coupling with piezo-resistance.
The inductance of series connection is hollow inductance, the inductance value >=20 μ H that we require.
We generally select discharge tube is ceramic gas discharge tube, and DC breakdown voltage is 470V-600V.
