Abstract
The utility model introduces a power transmission line tower grounding state remote online monitoring system. The system consists of a GPRS communication module (1) equipped with a solar power monitoring device, a control center server (2) and a computer (3), wherein the GPRS communication module (1) equipped with the solar power monitoring device, the control center server (2) and the computer (3) are successively connected in series. When the system is in use, the solar power monitoring device of the GPRS communication module 1 is arranged at a crossarm of a tower. A measurement result is sent by the device to the GPRS communication module 1 in a wireless communication manner and then is input into the control center server 2. After the analysis of the computer 3, the safety evaluation of the grounding state of the tower is acquired to guide the operation of the tower grounding maintenance work. The power transmission line tower grounding state remote online monitoring system provided by the utility model has the advantages that (1) online remote monitoring is carried out on the power transmission line tower grounding state in a control center; (2) direct guidance is provided for the power transmission line tower grounding operation and maintenance; (3) the power transmission line tower grounding state remote online monitoring system does not produce any negative effect on the original device of an electric power system.
Description
Technical field
The utility model belongs to the electrical engineering technical field, relates in particular to a kind of electric power line pole tower ground connection situation remote online monitoring system, is 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.
The utility model content
The technical matters that the utility model 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.
The technical solution of the utility model is; This electric power line pole tower ground connection situation remote online monitoring system that is provided; Referring to Fig. 1; As shown in Figure 1, (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 for it.) communication module 1, control center server 2, computing machine 3 be composed in series successively.
When this electric power line pole tower ground connection situation remote online monitoring system of the utility model 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 monitoring device adopts the alien frequencies signal; Injection 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 another 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; And measurement result is sent to GPRS communication module 1 through communication; 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 beneficial effect of the utility model is:
(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 utility model, 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 the utility model electric power line pole tower ground connection situation remote online monitoring system 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, the electric power line pole tower ground connection situation remote online monitoring system product of connecting successively and promptly constituting the utility model with reference to structured flowchart shown in Figure 1.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.
