Description

High-voltage intelligent magnetic meter pen and insulator intelligent detection equipment
Technical field
The invention relates to a kind of high-tension bus-bar checkout equipment, the insulator intelligent detection equipment that refers in particular to a kind of high-voltage intelligent magnetic meter pen and use this test pencil.
Background technology
Along with the further enforcement of national intelligent grid planning, UHV transmission line plays a part crucial to national intelligent grid construction, has also just become the normal indispensable part in service of UHV transmission line for the repair based on condition of component of UHV transmission line.Wherein, transmission line of electricity has the insulator that is used for fixing conductor, and insulator is the vitals that makes conductor maintenance electric property, thus most important to the regular detection of insulator, be the essential step of UHV transmission line repair based on condition of component.
At present, the intelligent checkout equipment of the insulator of domestic ultrahigh voltage alternating current transmission lines is less, existing checkout equipment as shown in Figure 1, (patent No. is: CN201120449131.X) to have a UHV transmission line insulator intelligent detecting instrument 9, leaning out two diameters from intelligent detecting instrument 9 is the parallel steel bar test pencil 91 of 2-3mm, during measurement, operating personnel's hands grasping and intelligent movable detector 9, the test side that makes two steel bar test pencils 91 is the two ends of the steel cap 81 of connect insulator 8 respectively, in order to detect the insulator physical characteristics.
Yet in the actual measurement operation process, adopt above-mentioned equipment Inspection insulator still to have following problem:
1. the two ends of the steel cap of insulator are cylindrical structure (such as Fig. 1), when its test side with the steel bar test pencil contacts, only be line contact even some contact, cause contact area less, easily loose contact is again because intelligent detecting instrument is that the operating personnel hands, when hand has shake, just more increased the incidence of loose contact situation, finally made measurement result inaccurate;
2. in measuring process, because testing is to carry out in the high-altitude, and the operating personnel needs two hands hold simultaneously checkout equipment, has to so that the operating personnel easily falls from high altitude, have very big potential safety hazard with the fixing health of both feet;
3. because insulator bunchiness shape, axial dimension is longer, in measuring process, need the hand-held checkout equipment of operating personnel constantly to move and carry out the detection of each section of insulator, and in every section detection, need again to make the test side of two steel bar test pencils and the careful contraposition of insulator to fit, complicated operating process like this, cause detection efficiency low, can't finish a large amount of testings on schedule;
4. intelligent detecting instrument is after energising, and the test pencil test side namely has high pressure, if this moment, the operating personnel touched the test side because of carelessness, then causes most probably getting an electric shock, and causes personal injury.
In the above-mentioned situation, the lighter's insulator is measured inaccurate, inefficiency, and severe one operating personnel is injured, so be badly in need of the checkout equipment of prior art is improved.And the inventor adopts the new test pencil of design to connect the combination of existing detector according to its in the industry working experience for many years, overcomes the problems referred to above.
Summary of the invention
For overcoming a series of serious problems described in the background technology, the object of the present invention is to provide a kind of high-voltage intelligent magnetic meter pen, be replaced by soft test pencil wire by the steel bar test pencil with the hard of prior art, and in the test pencil test side, be provided with magnetic part with the absorption insulator, operating personnel's both hands have not only been liberated to help fixture, ensured operating personnel's safety, but also make contacting of test pencil test side and insulator more tight reliable by the magnetive attraction effect, greatly reduced the generation of loose contact, made the detector measurement result more accurately and reliably.
