Detailed description of the invention
Referring to the drawings, in conjunction with specific embodiments, the present invention is described in detail.
Embodiment
As Figure 1-3, it is movably connected with insulating bar respectively including emitter, receptor and insulating bar, emitter and receptor；Insulating bar is telescopic, is made up of 3 joints, total length 5 meters.Described emitter is provided with jointing clamp；Described receptor is provided with hook.
Described emitter structures is, 8.92kHz HF signal generator, Automatic-boosting controller, power output circuit and output indicating circuit are sequentially connected with, and sampling protection circuit is connected with HF signal generator, Automatic-boosting controller and power output circuit respectively；Battery powers to above-mentioned HF signal generator, Automatic-boosting controller, power output circuit, output indicating circuit and sampling protection circuit；Described receiver architecture is, 8.92kHz high-frequency signal sensor, input circuit, amplifying circuit I, attenuator circuit, amplifying circuit II, digital filter circuit, 8.92kHz frequency selection circuit, power output circuit and speaker are sequentially connected, and battery gives above-mentioned high-frequency signal sensor, input circuit, amplifying circuit I, attenuator circuit, amplifying circuit II, digital filter circuit, frequency selection circuit, power output circuit and power speakers.
During use, emitter load alien frequencies signal to target line, draft the high-frequency signal that signal intensity is 8.92kHz, it is different from power frequency 50Hz, other end receptor at switch receives this high-frequency signal, if receptor can receive this high-frequency signal, then explanation switch is closing position.If receptor is not received by launched high-frequency signal, illustrate that switch, in a point position, at this moment can start to determine to work mutually, it is also possible to the disconnecting link of relieved operation switch both sides.
Emitter with the working condition of receptor is: temperature-20-45 DEG C, humidity ＜ 90%, degree of accuracy≤1%.
The present invention detects in experiment work mutually at 10 kilovolts of pinaster lines and 10 kilovolts of wave line contact vacuum switches, Successful tests in experiment work is detected mutually at 10 kilovolts of horse river lines and 10 kilovolts of kingwood line contact vacuum switches, use identification of the present invention accurate, safe and reliable, easy and simple to handle, practical, be easy to carry, obtain the trust of producers.
