Embodiment Construction
[0033] Specific embodiments of the present invention will be described in detail below.
[0034] A three-level network-based inspection method for substation hard press plates, in which the hard press plate inspection system adopts a three-level network structure, such as figure 1 As shown, it is composed of monitoring host 1, data repeater 2, and inspection device 3. The internal communication of the system is realized by RS485 bus, and the communication protocol is MODBUS protocol. The monitoring host 1 is connected to several data repeaters 2 through the RS485 bus, and the data repeaters 2 are connected to several inspection devices 3 through the RS485 communication line. As the central monitoring layer of the three-level network, the monitoring host is mainly responsible for sending data commands to the data repeater, and receiving and analyzing the data uploaded by the data repeater, so as to judge whether the pressure plate is switched on or off. The data repeater is th...

The invention discloses a transformer substation hard pressing plate routing inspection method based on a three-level network. The three-level network includes a three-level routing inspection networkcomposed of a monitoring host, a data repeater and a routing inspection device; according to the transformer substation hard pressing plate routing inspection method, routing inspection is carried out on hard pressing plates of a transformer substation by the three-level network at definite time or specifically. By adopting the method, real-time monitoring of the discharging state of the hard pressing plates of the transformer substation can be accurately and quickly achieved, and correctness analysis can be conducted on the discharging state of the pressing plates in a switching operation process, so that the discharging correctness of the pressing plates of the transformer substation is ensured, the correct movement of protective devices of the transformer substation is ensured, and therunning reliability of the transformer substation is improved.
Description
technical field [0001] The invention relates to the field of inspection and maintenance of substation hard press plates, in particular to a three-level network-based inspection method for substation hard press plates. Background technique [0002] In recent years, with the rise of smart substations, the pressure plates of relay protection equipment in substations have also been divided into "soft pressure plates" and "hard pressure plates". And the solid pressure plate on the protection device. In daily work, because the operation and maintenance personnel often operate the soft platen and pay more attention to it, they often neglect the management of the hard platen on site, resulting in a loose control of the commissioning and withdrawal of the hard platen on site. [0003] In addition, due to the transformation of the operation and maintenance mode, the operation and maintenance personnel need to manage several conventional substations with hard pressure plates or smart ...
