Embodiment Construction

[0014] Such as figure 1 As shown, the electric shock protector of the present invention includes a current sensor 1 arranged between the single-phase circuits, the current sensor 1 is connected to the input terminal of the controller 2, and the output terminal of the controller 2 is connected to the single-phase circuit The circuit breaker 3 between them is connected. The current value between the single-phase circuits is detected by the current sensor, and then transmitted to the controller. When the current value detected by the current sensor is too large, the controller 2 controls the circuit breaker to disconnect to ensure the safety of the circuit.

[0015] Here the current sensor 1 can be a Hall current sensor or a current transformer.

[0016] In order to be able to independently and manually detect whether the electric shock protector of the present invention can work normally, a detection switch 4 is connected between the single-phase circuits, and the closed detect...

Abstract

The invention relates to an electrical appliance element, and particularly relates to an electric shock safety protector, which comprises a current sensor arranged between single-phase circuits. The current sensor is connected onto the input end of a controller; and the output end of the controller is connected with a circuit breaker arranged between the single-phase circuits. After the above structure is adopted, current between the single-phase circuits is detected via the current sensor, the circuit breaker arranged between the single-phase circuits is controlled to be broken via the controller if the current is over large, the circuit breaker is controlled to be closed via a manual button in the case of safety, and the circuit works normally.

Description

technical field [0001] The invention relates to an electrical component, in particular to an electric shock protector. Background technique [0002] Electric shock protector is also called leakage protector. For some electrical equipment, when someone gets an electric shock accidentally, the power supply will be automatically cut off, which will not cause personal accidents. This is why the electric shock protector is installed. The circuit structure of the existing electric shock protector is loaded, and the cost is high. [0003] Chinese Utility Model Patent Specification CN202309027U discloses an automatic delay reset electric shock protector, which includes a first terminal, a second terminal, a first capacitor, a rectifier bridge stack, a second capacitor, a first zener diode, a transformer, a third Capacitor, fourth capacitor, first silicon diode, first resistor, second zener diode, transistor, second resistor, fifth capacitor, potentiometer, sixth capacitor, 555 int...
