In application, the acquisition module, the amplifying module and the testing module are positioned in the leakage protection device, and the alarm module is positioned on the surface of the leakage protection device. The leakage protection device is tested at regular time, so that safety accidents caused by failure of the leakage protection device can be reduced. For example, the test time is set to be once in two days, the alarm is given in time when the test result is failure, the user can maintain and replace the leakage protection device in time, the occurrence of safety accidents is reduced, and meanwhile, the test is performed by different people, so that the electric leakage protection device is more convenient and quicker.
Referring to fig. 2, the time assembly includes a timer for setting a test time and outputting a first time signal, an instant button, and a time controller. The instant button is used for collecting the user test time outside the timing and outputting a second time signal. The time controller is in signal connection with the timer and the instant key and is used for receiving the first time signal and the second time signal and outputting the time signal after receiving the signals.
In the application, the timer can set the test time, and the leakage protection device does not need to be tested in real time and can be tested at intervals. The condition that the test is forgotten easily occurs through manual interval test, and the test is not forgotten through timer timing test. And in the time beyond the timing, the user wants to perform the leakage protection test, which can be realized by an instant button. For example, the leakage protection test should be performed according to time 14, but the leakage protection test is required for removing the fault 13, and the operator can implement the leakage protection test by pressing the key.

In the application, the equipment of earth leakage protection device protection can not always appear the electric leakage condition, and when testing, in order to not disturb the normal operating of equipment, can obtain the electric current through friction electrification, test. On one hand, friction electrification does not need to consume a large amount of electric energy, and is environment-friendly. On the other hand, friction electrification can not interfere with normal operation of equipment, and is more practical and convenient.
The detection assembly is configured as an ammeter, and the ammeter is electrically connected with the conductive rod and is used for receiving the current signal and outputting current numerical data after detecting the electric energy.
In application, the current signal generated by friction is not fixed, and the leakage protection test needs a fixed range of current, so that the normal current of friction electrification can be obtained through the ammeter, and the subsequent leakage protection test is facilitated. For example, in the case of a current of 1 ten thousand milliamperes, and a current generated by friction electrification of 1 microampere and 10 microamperes, the processing results are different in the test process.

For example, the triboelectric current is 1 milliamp, and the leakage protection test needs to reach 100 milliamps, thus requiring 100 times amplification. If the triboelectrification current is 2 milliamperes, the amplification is only needed to be 50 times to reach 100 milliamperes. The friction electrification current is detected and calculated, and a more accurate current test signal can be obtained, so that a more accurate test result is obtained.

In the application, when the current of the outage of the leakage protection device is up to the current, the leakage protection device can be timely powered off for protecting the safety of equipment. The leakage protection device is powered off by tripping a switch of the leakage protection device, so that the switch of the leakage protection device needs to be observed when judging whether the leakage protection device works normally. For example, the amplified current is connected to the leakage protection device through a switch, whether the switch of the leakage protection device trips or not is observed through a camera, and whether the test is successful or not is judged.
The implementation principle of the embodiment of the application is as follows: firstly, setting test time according to a timer, and after the timer reaches the timing time, sending a signal to a manufacturing controller by the time controller, wherein the manufacturing controller controls the friction plate to rub and electrify, and the current is led to the conductive rod.
