摘要： A heating loop protective circuit, a respiration heating circuit and respiration aiding equipment are provided, wherein the heating loop protective circuit is connected to a heating loop and includes an acquisition sub-circuit, a suppression sub-circuit, a protective sub-circuit and a discharge sub-circuit; the acquisition sub-circuit collects input voltage of the protective sub-circuit and sends the input voltage to the suppression sub-circuit; the suppression sub-circuit clamps the input voltage and releases current through the discharge sub-circuit; and the protective sub-circuit performs short-circuit protection when the current is too high. In the present disclosure, the over-voltage protection is realized through the voltage clamp in such a manner of monitoring the voltage of the heating loop and suppressing the input voltage through the suppression sub-circuit, and then the over-current protection is realized through the protective sub-circuit when the circuit current is too high.

摘要： The present invention provides a protection device which includes a PTC component and a first non-resettable contact component which is connected electrically in parallel to the PTC component. A second non-resettable contact component is connected electrically in series to the PTC component, and when the PTC component is tripped by a current which is diverted by opening the contact of the first non-resettable contact component, the contact of the second non-resettable contact component opens due to heat which is generated by the PTC component.

摘要： A power-limit protection circuit with an efuse element. The power-limit protection circuit has an efuse element coupled between a first terminal and a second terminal. The power-limit protection circuit judges whether a calculated power signal defined from a current signal flowing through the efuse element and a voltage signal at a terminal of the efuse element is larger than a predetermined power threshold. When the calculated power signal is larger than the predetermined power threshold, the power-limit protection circuit increases an impedance of the efuse element to limit the current signal between the first terminal and the second terminal such that the power delivered through the efuse element is limited within the predetermined power threshold.

摘要： A circuit apparatus measures, records, transmits, and displays actual and estimated power consumption in a branch circuit of an electrical distribution system. The apparatus includes a display driver coupled to one or more current sensors which derives or estimates power consumption from measured current. The accuracy of power consumption is improved by additional measurement of actual supplied voltage. A plurality of current sensors determine differential current to provide ground fault interruption to a desired range of precision. A store enables display of surge and average current measurements and power measurements in addition to immediate results.
