Described signal processing module can be provided with a set point, current detection module is in order to the detected value of detection from the electric current of the power line process of plug body, with detected value feed signals processing module, signal processing module with this detected value after treatment, compare with the set point of its setting, when this detected value surpasses or during less than set point, the control alarm module is reported to the police, the electrical equipment that the prompting user is connected with plug body this moment breaks down, and above-mentioned design can realize phenomenons such as electric leakage, overcurrent, short circuit.
Described current detection module comprises a zero sequence current mutual inductor, and the live wire of the power line of described plug body and center line pass described zero sequence current mutual inductor respectively, and the output of described zero sequence current mutual inductor connects described signal processing module.When the electrical equipment operate as normal that is connected with plug body, the electric current that flows through in the live wire of plug body and the center line equates, electric current one-in-and-one-out, the output of zero sequence current mutual inductor secondary coil no-voltage.Live wire in penetrating zero sequence current mutual inductor and current in middle wire imbalance can produce and the proportional voltage signal of electric current at the output of zero sequence current mutual inductor, and signal processing module forms detected value after handling this voltage signal.
Described signal processing module also connects a display, and described display is arranged on described plug body surface.The detected value that described signal processing module detects the electric current obtain with current detection module is presented on the display, after treatment for checking.
Described alarm module comprises a sounding component.By audible alarm prompting user.
Described alarm module can also comprise two light-emitting components, and one is the red light-emitting component that sends red light, and one for sending the Yellow luminous element of sodium yellow, when detected value a certain more among a small circle time the in set point, trigger Yellow luminous element, prompting electrical equipment at this moment breaks down, and should note; When detected value a certain in a big way time the in set point, trigger red light-emitting component, the inspection of should cutting off the power supply risk of disturbance appears, in the electrical equipment of prompting this moment.By the light-emitting component of two kinds of colors, realize reporting to the police step by step.
Described signal processing module connects an alarm switch, and described alarm switch is arranged on the described plug body.When the user does not need to report to the police, disconnect alarm switch and get final product.
Described zero sequence current mutual inductor can also connect a relay by an amplifying circuit, and described relay is connected with the power line of described plug body.When the voltage signal of zero sequence current mutual inductor output is enough big, and after amplifying by amplifying circuit, can disconnect by trigger relay, effectively the electrical equipment that is connected with plug body of protection.
Can also be connected a cut-off switch between described zero sequence current mutual inductor and the described relay, described cut-off switch is arranged on the described plug body.When the user does not need direct deenergization, disconnect cut-off switch and get final product.
Beneficial effect: owing to adopt technique scheme, when the electrical equipment that is connected with the utility model broke down, in time the alarm user effectively avoided the danger that causes because of apparatus failure.
