Further, detection of electrical leakage terminal mounts at the node to be detected into three-level power grid.
Technical solution to facilitate the understanding of the present invention, is below described in detail technical solution of the present invention.
As depicted in figs. 1 and 2, the current leakage detection system of no local communication network provided in an embodiment of the present invention is in no local
When testing under the platform area of communication network, the open-close type mutual inductor of detection of electrical leakage terminal front end is opened, and is hung under affiliated platform area
It is switched on zero firewire circuit of each node to be measured of three-level power grid, the three-level branch side (or three-level user side) being connect with second level branch
With PDA scanning electric supply meter number and detection of electrical leakage terminal number, the second level branch side scanning branch guarantor number being connect with total security and electric leakage
Terminal number is detected, total security number and detection of electrical leakage terminal number are scanned in level-one total security side, by pair of detection of electrical leakage terminal and node to be measured
It should be related to binding, and mark three-level power supply relationship, for example, user 1, user 2, which belong to branch, protects 1, user 3, user 4 belong to branch
N is protected, each branch, which is protected, belongs to total security, forms the corresponding relationship document of main website default after the completion of binding in a pda, needs
Bright book, the corresponding relationship document can regard the second memory module as.
As depicted in figs. 1 and 2, want to check the electric leakage data (or test data) of detection of electrical leakage terminal during the test
When PDA need to be only moved to test in detection of electrical leakage terminal wireless data sending module communication context in, selected with PDA
When single detection of electrical leakage terminal, the electric leakage data of corresponding detection of electrical leakage terminal will be uploaded to by wireless data sending module
In the wireless data receipt modules of PDA, and electric leakage data are shown in the second display module, furthermore, if it is desired to check whole leakages
When the data of electro-detection terminal, whole detection of electrical leakage terminals are received with PDA, all detection of electrical leakage terminals for having electric leakage will be by number
It is uploaded in the wireless data receipt modules of PDA according to by respective wireless data sending module, and in the second display module
Show data.
Furthermore, it is necessary to illustrate explanation, although its specifically define wireless module include wireless data sending module and
Wireless data receipt modules, but itself merely to indicate data transmission process, it should be understood that either wireless data send mould
Block or wireless data receipt modules all have the function of data transmission and reception data simultaneously.
In addition, as shown in Figure 1, the PDA document for having recorded corresponding relationship is imported into the first memory module of main website by main website
It is interior, or according to the corresponding relationship direct editing corresponding relationship of on-the-spot record, wherein first memory module can be storage document.
In addition, as illustrated in fig. 1 and 2, detection of electrical leakage terminal includes for detecting and saving data of leaking electricity at node to be measured
Detection of electrical leakage module (not shown), so that it can send the electric leakage data saved in detection of electrical leakage module, for example, surveying
After examination, user fetches detection of electrical leakage terminal closedown, and mobile communication sending module works as movement still in working condition at this time
To when having communication network area, the test data in detection of electrical leakage terminal will be by mobile communication sending module active upload extremely
In main website mobile communication receiving module, mobile communication sending module is automatically closed after the completion of uploading in detection of electrical leakage terminal data, main
It stands and the tree-shaped distribution relation of three-level power supply grid is formed according to corresponding relationship, and received data are unified according to tree-shaped distribution relation
Analysis, and finally obtain electric leakage conclusion, it is shown in the data disaply moudle of main website, in addition, it should be noted that, PDA is live
The electric leakage data of the detection of electrical leakage terminal of acquisition are also the electric leakage data saved in detection of electrical leakage module.
In addition, below in the method for the citing acquisition conclusion of attached drawing 2: assuming that (can be for 24 hours) entire three whithin a period of time
User 1 under only branch protects 1 in grade protection scope has drain conditions, and the three-level user 1 under not only branch protects 1 at this time can detect
The electric leakage out, while hanging over the detection of electrical leakage terminal of second level branch 1, hanging over the detection of electrical leakage terminal of level-one total security, also can it examine
Same drain conditions are measured, main website can clearly tell tester's rain supply in the user 1 of the third level at this time；Similarly pole
End ground, user 1, user 2 and user 3 use A, B, C phase single phase power supply respectively below branch 1, and 3 users occur same simultaneously
The electric leakage of feature, the detection of electrical leakage terminal for hanging over three-level user 1, user 2 and user 3 at this time can detect identical electric leakage feelings
Condition, and detection of electrical leakage terminal in second level branch 1, the detection of electrical leakage terminal that hangs at level-one total security cannot detect electric leakage feelings
Condition (such situation belongs to three-phase equilibrium feature), main website can clearly tell tester's rain supply in user 1, user at this time
2, in user 3；Further, when route leaks electricity, for example only on the route between feeder pillar 1 and user 1, user 2
Occur, hangs over three-level user 1 at this time, the detection of electrical leakage terminal nothing of user 2 detects electric leakage, but hangs over the leakage of second level branch 1
Electro-detection terminal hangs over the total detection of electrical leakage terminal of level-one and can detecte identical drain conditions, and tester is only at this time
It line walking need to can be checked between branch 1 and user 1, user 2.
In conclusion being tested by means of above-mentioned technical proposal of the invention in the area of no local communication network
When, only detection of electrical leakage terminal need to be switched on and pass through PDA (Personal Digital Assistant, palm PC) etc. intelligently
Mobile terminal binding, it is easy to operate.Meanwhile it still can pass through the intelligence such as wireless data sending module PDA in test
Wireless data receipt modules in mobile terminal check electric leakage data in real time, facilitate label electric leakage position.
It, only need to be by detection of electrical leakage terminal closedown, when being moved to wireless communication networks in addition, after test
Place, electric leakage data will be uploaded to automatically main website by mobile communication sending module, detection of electrical leakage terminal after data upload
Mobile communication sending module is closed, and without the operation of repeat switch machine, is improved work efficiency, and main website is according to established
Corresponding relationship by data unified distribution, processing, and obtains final electric leakage conclusion, eliminates the mass data analysis of test man
Work, and improves the accuracy of fault location and rectification, also achieve the area of no mobile communication network for radio area
System electric leakage investigation, while electric leakage conclusion is obtained by three-level power supply relationship, investigation convenience, accuracy are improved, and improve
Working efficiency.
