Permanent Magnetic Vacuum Contactor

     Sanhe SEK intelligent permanent magnet vacuum contactor, as a new generation of medium voltage vacuum contactor, is fitted a permanent magnet mechanism to close/open the dynamic and static contacts of the vacuum interrupter in a direct motion. SHVC intelligent permanent magnet vacuum contactor can be widely used in the three-phase AC system below 12kV and rated frequency 50Hz/60Hz where multiple opening and closing operation cycles are required, and it is especially suitable for users who operate frequently. SHVC intelligent permanent magnet vacuum contactor adopts a wide-voltage, high-efficiency and reliable electronic control module, and uses STM32 mainstream chips inside. It has the characteristics of fast response to closing and opening, LED indication for closing and opening, and alarm auxiliary contact output.     SHVC intelligent permanent magnet vacuum contactor has the characteristics of energy saving, material saving, fireproof, explosion-proof, small size, long life, low maintenance cost, reliable operation and no pollution.  It is widely used in the control and protection of power transmission and distribution systems in the fields of electric power, machinery, metallurgy, mining, petroleum, chemical industry, railway, broadcasting, communications, and transportation. Using the ideal technology of breaking current in a vacuum environment, as well as extremely high reliability and compact structure, the contactor can be used under particularly harsh conditions. They are suitable for control and protection (with fuses) circuits, substations and distribution stations, motors, transformers, capacitor banks, etc. Features:Main features of SHVC intelligent permanent magnet vacuum contactor are as follows:maintenance freereliable vacuum technologyfrequent operation supportmonostable permanent magnet actuatorlong electrical and mechanical lifewide voltage power supply modulesmall closure valuecompact structureSpecification SheetTechnical dataSHVC-7P-200/400/630SHVC-10P-200/400/630Rated voltageUr(kV)7.212Rated currentIe(A)200/400/630200/400/630Rated frequencyfr(Hz)50-6050-60Rated short-time withstand currentIk(kA)46.3Rated peak withstand currentIp(kA)1016 Rated short circuit breaking currentIo(kA)45Rated short-circuit making currentIc(kA)1012.5capacitive switch current Itc(A)230230Operating frequency(Times/hour)900900Mechanical life(Times)30×10430×104Electrical life(Times)AC-3:25×104AC-3:25×104(Times)AC-4:10×104AC-4:10×104Rated lightning impulse withstand voltageUp(kV)6075Rated power frequency withstand voltage (1min)Ud(kV)3242Three-phase closing synchronization(ms)≤2.0≤2.0Contact bounce time(ms)≤5.0≤5.0Conductive loop resistance of each phase (20ºC)(μΩ)≤180≤180Control loopControl module- rated operating voltageUr(V)110V/220V(AC,DC)Rated operating voltage range(V)0.85Ur~1.1UrLatching mode Permanent magnet Operating power DC110V,3A DC220V,1.5A AC220V,1AClosing time(ms)≤50Inherent opening time(ms)≤201min power frequency withstand voltage(kV)2Auxiliary contacts-quantity 5 open 5 closeConventional heating current(A)6Mechanical life(Times)5×106Electrical life(Times)2×106Rated working current DC/AC110V,0.4A DC/AC220V,0.2AConditions:  SEK ntelligent permanent magnet vacuum contactor can be used normally under the following environmental conditions:Ambient temperature: -25ºC~+40ºCRelative humidity: ≤95% (daily average); ≤90% (monthly average)Altitude: ≤2000m (SHVC-7); ≤1000m (SEK-10, SHVC-15)Water vapor pressure: ≤2.2×10-3Pa (daily average); ≤1.8×10-3Pa (monthly average)The surrounding air should not be significantly polluted by corrosive or flammable gas, water vapor, etc.No frequent severe vibrationDuring operation, the inclination angle between the installation plane and the horizontal plane is not over 5°Reference &Executive standardsSEK intelligent permanent magnet vacuum contactor complies with the standards of most industrial countries and fully complies with the following standards:IEC 62271-106:2011 High-voltage switchgear and controlgear-Part 106:Alternating currentcontactors, contactor-based controllers and motorstarters"IEC 60282-1:2020 High-voltage fuses-Part 1: Current-limiting fusesGB/T 14808-2016 "High-voltage AC contactor, contactor-based controller and motor starter"GB 16926-2016 "High-voltage AC load switch-fuse combination electrical appliance"GBT 11022-2011 "Common technical requirements for high-voltage switchgear and control equipment standards"GB/T 15166.2-2008 "High Voltage AC Fuses Part 2: Current Limiting Fuses"JB 7122-2007 "Basic requirements for AC vacuum contactors"Permanent Magnet StructureStandard fitting  /* January 22, 2024 19:08:37 */!function(){function s(e,r){var a,o={};try{e&&e.split(",").forEach(function(e,t){e&&(a=e.match(/(.*?):(.*)$/))&&1
