Ground screen comprehensive monitoring and intelligent maintenance system

Abstract

The invention discloses a ground screen comprehensive monitoring and intelligent maintenance system. The system is composed of a front-end detector (1), a ground screen comprehensive monitor (2), a rainwater collector (3), an ion supplying device (4), a superior industrial digging machine (5), an electric control water pump (6), an electric control valve (9), a PH (potential of hydrogen) modifier (7) and a ration pool (8), wherein a ground screen and an instrument, the ground screen and monitoring as well as a GPRS (general packet radio service) module are mutually combined, thus whole-screen intellectualized remote monitoring and seamless data transmission are realized, the operating condition of the ground screen is remotely monitored in real time (on a national scale), and the monitoring condition is reported in real time through a prewarning and warning device; and according to the reported monitoring information, an attendant can set parameters for an intellectualized system according to corresponding conditions, comprising setting resistance prewarning, an alarm value and automatic-start regulating equipment.

Description

technical field [0001] The invention relates to a ground network comprehensive monitoring and intelligent maintenance system, in particular to an intelligent system capable of remote monitoring and maintenance of the ground network. Background technique [0002] In recent years, many substations in China have caused major accidents due to lightning strikes. The reasons for these accidents are mostly related to the unqualified grounding resistance of the ground grid. Unqualified ground network will not only cause great accidents in power transmission, but also cause signal interference and even communication accidents such as wrong codes for some terminal precision equipment or mobile base stations and other environments with precise transmission signals. Therefore, it is very important to establish a qualified ground network. More and more studies have also shown that the ground network plays a vital role in the stable operation of a system. Therefore, relevant standards and...

Unqualified ground network will not only cause great accidents in power transmission, but also cause signal interference and even communication accidents such as error codes for some terminal precision equipment or mobile base stations and other environments with precise transmission signals

Therefore, it is very important to establish a qualified ground network. More and more studies have also shown that the ground network plays a vital role in the stable operation of a system. Therefore, relevant standards and specifications have been issued one after another, causing More and more people pay attention to it, but in the relevant regulations of our country, only the parameters of the grounding resistance are specified in detail, but there are still no detailed specifications for the materials for the construction of the ground grid, resulting in many units in the During the design and construction, the service life of the ground net and the change of seasonal factors were not considered, so that the rainy season met the standard, but the dry season did not meet the standard; or after a period of use, the materials used in the ground net were corroded and fell off, resulting in ground net failure. Substandard

In order to avoid major accidents caused by unqualified ground grids, people carry out regular inspections on the ground grids. Because in power or communication systems, they are generally built in relatively remote places, as such a large power substation or communication base station Under the premise of the quantity, it is also an extremely complicated work to conduct a test every quarter, which consumes a lot of manpower and material resources, and is more seriously affected by human factors.
