Description
Technical field
The utility model relates to a kind of circuit, particularly one dropout executive circuit and residual current circuit breaker.
Background technology
In existing dropout executive circuit and residual current circuit breaker, adopt two diode reverse parallel connections, form clamp circuit, release release reversed charge, but the output AC value at these clamp circuit two ends is only at below 200mA, phase angle test request could be met, and need now to meet identical phase angle test request when higher interchange value.
Utility model content
Be limited at the deficiency of 200 below mA to overcome interchange value, the utility model provides a kind of dropout executive circuit and residual current circuit breaker.
The technical scheme that the utility model adopts is: a kind of dropout executive circuit and residual current circuit breaker, it comprises zero sequence current mutual inductor ZCT, two-way Transient Suppression Diode D1, tantalum electric capacity, release, difference two-way Transient Suppression Diode D1 in parallel, tantalum electric capacity and release between the two ends of zero sequence current mutual inductor ZCT.
Described tantalum electric capacity is one, and described zero sequence current mutual inductor ZCT is low output characteristic instrument transformer.
Described tantalum electric capacity is two, is connected in parallel on the two ends of zero sequence current mutual inductor ZCT after series connection, and described zero sequence current mutual inductor ZCT is high output characteristic instrument transformer.
It comprises this dropout executive circuit.
This residual current circuit breaker is A characteristic residual current circuit breaker.
The beneficial effects of the utility model are: the two-way Transient Suppression Diode D1 of the utility model can reduce by 135 ° of phase angle current values in pulsating direct current, regulate ± 0 °, ± 90 °, current value balance between ± 135 ° of six phase angles, make the interchange value upper limit of A characteristic residual current circuit breaker be increased to 230mA by the highest original 200mA, corresponding phase angle current value all can meet standard-required.
Accompanying drawing explanation
Fig. 1 is the circuit diagram containing 1 tantalum electric capacity of the present utility model.
Fig. 2 is the circuit diagram containing 2 tantalum electric capacity of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model embodiment is described further:
As Fig. 1, shown in Fig. 2, a kind of dropout executive circuit and residual current circuit breaker, it comprises zero sequence current mutual inductor ZCT, two-way Transient Suppression Diode D1(and TVS pipe), tantalum electric capacity, release, difference two-way Transient Suppression Diode D1 in parallel between the two ends of zero sequence current mutual inductor ZCT, tantalum electric capacity and release, 135 ° of phase angle current values in pulsating direct current can be reduced with two-way Transient Suppression Diode D1, regulate ± 0 °, ± 90 °, current value balance between ± 135 ° of six phase angles, the interchange value upper limit of A characteristic residual current circuit breaker is made to be increased to 230mA by the highest original 200mA, corresponding phase angle current value all can meet standard-required.
Residual current circuit breaker is A characteristic residual current circuit breaker, and it comprises this dropout executive circuit.
Zero line L and live wire N,
Without in leakage current situation in the use electric line through residual current circuit breaker, its current phasor through zero sequence current mutual inductor ZCT and be zero, now zero sequence current mutual inductor ZCT secondary Non voltage output, operating circuit non-transformer inputs, release executive circuit does not work, residual current circuit breaker normally works, rearmounted circuit normal power supply.
Have leakage current situation in the use electric line through residual current circuit breaker under; its current phasor through zero sequence current mutual inductor ZCT and non-vanishing; now zero sequence current mutual inductor ZCT secondary has voltage to export; operating circuit has power supply to input; when being more than or equal to the setting current value of residual current circuit breaker with leakage current in electric line; release executive circuit works; driving release is threaded off; release drives residual current circuit breaker mechanical unlocking; circuit breaker tripping cuts off circuit power, reaches the effect of the rearmounted circuit of protection and electrical appliance.
TVS pipe, also has shock resistance surge simultaneously and absorbs the effect of trip coil L1 releasing reverse electric charge.
As shown in Figure 1, described tantalum electric capacity is a C1, and described zero sequence current mutual inductor ZCT is low output characteristic instrument transformer.
As shown in Figure 2, described tantalum electric capacity is two C1/C2, is connected in parallel on the two ends of zero sequence current mutual inductor ZCT after series connection, and described zero sequence current mutual inductor ZCT is high output characteristic instrument transformer.
Below described by reference to the accompanying drawings example is only preferred implementation of the present utility model, and the restriction not to protection range of the present utility model, and any improvement done based on the utility model spirit all ought within the utility model protection range.
