Embodiment 1
[0026] An intelligent inspection system for a leakage protector in a distribution network, including a portable leakage protector live tester, a server, a background management system, and a leakage protector action alarm device. The portable leakage protector live tester passes through the server and the background The management system communicates with the connection,
[0027] The portable leakage protector live tester is used to measure the operating current and operating time of the leakage protector, and the data is automatically sent back to the background and uploaded to the data management system through the GPRS module. Its structure mainly includes a portable intelligent leakage protector live tester, which is composed of a single-chip control unit, a measurement module, a man-machine interface module, a barcode scanning module, a GPRS data transmission module, a storage module, and a clock module. (attached image 3 )
[0028] At the beginning of the establishmen...

The invention discloses an intelligent patrol inspection system for leakage protectors of a power distribution network. The intelligent patrol inspection system for the leakage protectors of the power distribution network comprises a portable leakage protector electrified tester, a server, a backstage management system and a leakage protector action alarming device, wherein the portable leakage protector electrified tester is in communication connection with the backstage management system through the server, all the leakage protectors in a district needing patrol inspection are numbered with serial numbers with unique IDs, and a unique barcode is attached to each leakage protector. According to the intelligent patrol inspection system for the leakage protectors of the power distribution network, solid-state relays are adopted, the advantage of being short in connection time and disconnection time is achieved due to the fact that no mechanical contact is arranged, the stability of measurement and the measuring precision of action time are improved, and meanwhile electric isolation can further be achieved.
Description
technical field [0001] The invention relates to a detection device for a leakage protector of a distribution network, in particular to an intelligent inspection system for a leakage protector of a distribution network. Background technique [0002] With the deepening of smart grid construction, people have higher and higher requirements for safe electricity consumption after the transformation of rural power grids, and higher and higher requirements for the intelligent level of power grids. Leakage protector is an important device widely used in low-voltage AC distribution network to ensure the safety of electricity consumption, and has been vigorously popularized and promoted in recent years. However, in the long-term operation of the leakage protector, its performance indicators will inevitably change, which may cause misoperation or refusal to operate, and the protection cannot be activated when humans and animals get an electric shock; Hidden dangers have been left, en...
