【摘要】：針對高壓隔離開關(guān)安裝過程中觸指壓力的檢測需求,提出了一種可在分合閘過程中實(shí)時(shí)連續(xù)測力的新型觸頭。采用機(jī)械原理,推導(dǎo)了觸頭受力和觸指變形之間的關(guān)系。在考慮實(shí)際工況的前提下,給出了測力觸頭的結(jié)構(gòu)設(shè)計(jì)。最后在所建的高壓隔離開關(guān)試驗(yàn)平臺(tái)上對隔離開關(guān)分合閘運(yùn)動(dòng)過程中的觸頭壓力進(jìn)行了測試。試驗(yàn)結(jié)果表明:設(shè)計(jì)的測力觸頭可以對觸指壓力進(jìn)行實(shí)時(shí)連續(xù)檢測,連桿長度的變化會(huì)使觸頭觸指嚙合位置不正,觸指單邊壓力增大;根據(jù)觸指壓力變化曲線可以判斷單相導(dǎo)電臂分合閘同步性和三相同期性檢測。因此,該新型測力觸頭可對高壓隔離開關(guān)的安裝提供幫助指導(dǎo)。
[Abstract]:In order to meet the need of detecting the contact pressure during the installation of the high voltage isolator, a new type of contact is proposed, which can measure the force in real time and continuously during the process of opening and closing. The relationship between contact force and contact deformation is deduced by using mechanical principle. The structural design of the force measuring contact is given on the premise of considering the actual working conditions. Finally, the contact pressure in the process of switch opening and closing is tested on the high voltage isolating switch test platform. The test results show that the designed force measuring contact can detect the contact pressure continuously in real time, and the change of the connecting rod length will cause the contact finger to be engaged in a wrong position and the one-sided pressure of the touch finger can be increased. According to the pressure change curve of touch finger, the synchronous and three-phase synchronism of single-phase conductive arm can be judged. Therefore, the new force-measuring contact can provide guidance for the installation of high-voltage disconnector.
