After adopting the above technical scheme, the signal sample circuit of mutual inductor T0, resistance R0, capacitance C0 composition, the letter of acquisition
Number via operational amplifier U0A composition follower, resistance R3, capacitance C2 composition circuit, obtain signal Bj_Ia, Ia_H；Mutually
Sensor T0, resistance R0, the signal sample circuit of capacitance C0 compositions, the signal of acquisition is via operational amplifier U0B, resistance R1, electricity
The inverting amplifier circuit module of R2, capacitance C3 composition is hindered, obtains signal Ia_L；Two paths are formed at signal independent mutually
Passage is managed, the normal work of another way is not interfered with wherein being out of order all the way, enhances the reliability of signal.
Description of the drawings
Fig. 1 is the circuit diagram of the utility model.
Specific embodiment
With reference to shown in Fig. 1, folk art term bit arithmetic amplifier circuit provided by the utility model includes mutual inductor T0 and capacitance C0
And the two is connected, and resistance R0 is parallel between mutual inductor T0 and capacitance C0, capacitance C0 one end is connected with operational amplifier U0A, fortune
It calculates the amplifier U0A other ends and is connected with resistance R3, capacitance C2 is equipped between operational amplifier U0A and resistance R3, capacitance C0 is another
End is connected with operational amplifier U0B, operational amplifier U0B other ends connection resistance R1, and the resistance R1 other ends are connected to capacitance C0,
Resistance R2 is parallel on operational amplifier U0B, the operational amplifier U0B other ends are connected with capacitance C3.
Utility model works principle is as follows：Mutual inductor T0, resistance R0, the signal sample circuit of capacitance C0 compositions, acquisition
Signal formed via operational amplifier U0A follower, resistance R3, capacitance C2 composition circuit, obtain signal Bj_Ia, Ia_
H；Mutual inductor T0, resistance R0, the signal sample circuit of capacitance C0 compositions, the signal of acquisition is via operational amplifier U0B, resistance
R1, resistance R2, the inverting amplifier circuit module of capacitance C3 compositions, obtain signal Ia_L；Export the fortune of signal Bj_Ia, Ia_H
It is parallel relationship to calculate amplifier U0A and export the operational amplifier U0B of signal Ia_L, wherein signal is out of order all the way, not shadow
Ring another way signal normal work.So design has great importance for the circuit applied to overcurrent protection field,
In arbitrary signal all the way be out of order, another way signal still has protective effect, instrument and meter, overcurrent as the application circuit
The products such as protector, operation are more reliable and more stable.
