After the leakage protection switch is put into operation, it must be effectively managed to ensure that the leakage protection maintains a good operating state and truly plays a protective role. The management work mainly has the following aspects:
1. After the leakage protection switch is put into operation, it should consciously establish an operation record and improve the corresponding management system;
2. After the leakage protection switch is put into operation, under the power-on state, press the test button once or twice a month to check whether the leakage protection switch is normal and reliable, especially in the thunderstorm season.
3. Regularly analyze the operation of the leakage protection switch and replace the faulty leakage protection switch in time;
4. The maintenance of the leakage protection switch should be carried out by professionals. If there is any abnormality during operation, it should be handled by an electrician to avoid expanding the scope of the accident;
5, after thunderstorm or other unexplained reasons to make the leakage protection switch action, should be checked and analyzed;
6. After the leakage protection switch is operated, if the cause of the accident is not found after inspection, the test is allowed to be closed once. If it is operated again, the cause should be identified, the fault should be found, and if necessary, the action characteristic test should be carried out, and the power transmission should not be forced continuously. Except that it is confirmed by the inspection that the leakage protection switch itself has failed, it is strictly forbidden to remove the leakage protection switch forcibly sending power;
7. Before the leakage protection switch of the exiting operation is used again, the action characteristic test shall be carried out according to the items specified by the relevant department;
8. The operating characteristics of the leakage protection switch are set by the manufacturer and used according to the product manual.
9. After an accidental electric shock accident occurs within the protection range of the leakage protection switch, the operation of the leakage protection switch should be checked, and the reason for failing to protect the function should be analyzed. The site should be protected before the investigation, and the leakage protection should not be removed. switch;
10. In order to check the operating characteristics and changes of the leakage protection switch during operation, the operational characteristics test should be performed periodically. The characteristic test items include: testing the leakage current value, testing the leakage current value, and testing the breaking time;
11. When the leakage protection switch is tested for operational characteristics, special test instruments that have passed the test of relevant national departments shall be used. It is strictly forbidden to use the test method of direct contact with the grounding device.
12. In addition to the periodic test of the leakage protection switch, the leakage protection switch should be regularly checked and maintained according to the requirements of the low-voltage electrical equipment.
