Abstract
The invention discloses a remote online monitoring system for the grounding condition of a transmission line tower. The system consists of a general packet radio service (GPRS) communication module (1) with a solar monitoring device, a control center server (2) and a computer (3), which are sequentially connected in series. When the system is used, the solar monitoring device of the GPRS communication module (1) is arranged at a crossarm of the tower, and transmits a measurement result to the GPRS communication module (1) in a wireless communication way; the GPRS communication module (1) inputs the measurement result into the control center server (2); and the computer (3) performs analysis to obtain a security assessment on the grounding condition of the tower to instruct grounding and maintenance operation over the tower. The system has the advantages of: (1) remotely monitoring the grounding condition of the transmission line tower in a control center on line; (2) providing a direct instruction for the grounding and maintenance operation over the transmission line tower; and (3) avoiding adverse impact on the conventional devices of a power system.
Description
Technical field
The invention belongs to the electrical engineering technical field, relate in particular to a kind of electric power line pole tower ground connection situation remote online monitoring system, be applicable to the ground connection situation of electric power line pole tower is carried out online remote monitoring.
Background technology
Overhead transmission line is located in the wilderness, and the several hundred kilometers of being continuous is struck by lightning to thousands of kilometers easily, causes tripping operation to have a power failure, and shows according to China's electric network fault statistic of classification, and in total tripping operation number of times of high-tension line operation, the tripping operation number of times that thunderbolt causes accounts for 40%～70%.Reducing powerline pole tower ground resistance is the major measure that improves the line thunder protection level, reduces lightning outage rate.In the actual motion,, cause electric power line pole tower down conductor bad connection, cause that stake resistance sharply rises, thereby lightning outage rate is risen owing to burn into manual breakage, construction reason such as lack of standardization.Inspection to the down conductor fault is judged; The way that adopts at present usually is: the detect by an unaided eye corrosion situation of ground lead matrix section on ground of maintainer; And firmly shake ground lead and whether rupture with the shallow-layer part of observing below the face of land; This method can't be judged inner corrosion condition and the extent of corrosion of lead-in wire antirust coat at all, and is powerless especially for the corrosion situation below the ground lead face of land; And, also can make its surface soil more loose, thereby cause the downlead corrosion to be accelerated if firmly shake for the down conductor of partial corrosion.Yet up to the present also still do not have to occur specially the electric power line pole tower ground state is monitored the facility with state estimation.
Summary of the invention
The technical matters that the present invention will solve is; Backward situation to prior art; A kind of electric power line pole tower ground connection situation remote online monitoring system is provided; This system can make the operational management personnel stay indoor in control center just can accurately understand the ground connection situation of shaft tower, thereby can formulate the ground connection maintenance scheme of problem shaft tower in time targetedly, improves the safety operation level of electric system.
Technical solution of the present invention is; This electric power line pole tower ground connection situation remote online monitoring system that is provided; Referring to Fig. 1; It is as shown in Figure 1, and (abbreviation of English " General Packet Radio Service ", Chinese translation is " a communication packet wireless business " by the GPRS that is furnished with the sun power monitoring device.) communication module 1, control center server 2, computing machine 3 be composed in series successively.
When the of the present invention this electric power line pole tower ground connection situation remote online monitoring system that constitutes thus uses 1 of GPRS communication module is joined the sun power monitoring device and be installed in shaft tower cross-arm place; This device adopts oscillator to produce alien frequencies but not the power frequency sine wave signal; Injection comprises iron core, is enclosed within the power coil on the down conductor after carrying out power amplification, in the down conductor loop, produces electric current through electromagnetic induction; Measure coil with one again and measure the electric current that flows through on the downlead,, calculate down conductor loop conducting resistance in conjunction with the pumping signal in the power coil; Through communication measurement result is sent to GPRS communication module 1; This GPRS communication module 1 is with the measurement result input control center server 2 that receives; Use conventional method to combine historical data to carry out analysis-by-synthesis through the computing machine 3 that links to each other with control center server 2 again; Draw safety assessment, thereby instruct the operation of tower grounding maintenance work the tower grounding state.
The invention has the beneficial effects as follows:
(1), can carry out online remote monitoring to the electric power line pole tower ground connection situation that monitoring device is housed in control center;
(2), the monitoring and evaluation result can provide direct guidance for the operation maintenance of electric power line pole tower ground connection;
(3), the operation of monitoring device and system does not produce any negative effect to the original device of electric system.
Description of drawings:
Fig. 1 is the structured flowchart of a specific embodiment of the present invention, is denoted as among the figure:
The 1-GPRS communication module,
The 2-control center server,
The 3-computing machine.
Embodiment:
Referring to concrete embodiment of electric power line pole tower ground connection situation remote online monitoring system of the present invention shown in Figure 1, the GPRS communication module 1 of this embodiment adopts the GTM900-C module that flies to insult embedded company.Control center server 2 adopts the prosperous China in Chinese Wuhan to be prone to the double-core server that automatic control equipment company limited produces, and the cabinet of this server is an IPC-610-L type cabinet, and the used industrial motherboard of this cabinet is to grind magnificent company to produce AIMB-763VG type industry motherboard.The computing machine 3 employing places of production are that the DELL company of Chinese Foochow produces OPTIPLEX series 380 type computers.Said GPRS communication module 1, control center server 2, computing machine 3 be by above-mentioned technical solution, and connecting successively with reference to structured flowchart shown in Figure 1 promptly constitutes electric power line pole tower ground connection situation remote online monitoring system product of the present invention.This product is proved to be respond well, esy to use, safe and reliable through trial run, reaches designing requirement fully.
Claims (1)
1. an electric power line pole tower ground connection situation remote online monitoring system is characterized in that, it is composed in series by the GPRS communication module (1) of being furnished with the sun power monitoring device, control center server (2), computing machine (3) successively.
