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.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention Within mind and principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
