ptc浪涌抑制器
ptc surgesuppressor
应用范围 field of application
主要应用于各类交流接触器
it is mainly applied inac contactor.
概 述 general
电感性电路的开/关会引起过电压,尤其是断开接触器线圈时,导致释放出存储在磁流电路中的电磁能量,会产生过电压波和极高的振幅:高达几千伏,严重干扰了电子设备,甚至烧坏了某些敏感性的部件和接触器触点。本产品与接触器线圈并联连接可以迅速有效降低斩波,抑制与其相关的高频率,保护电子设备和接触器触点。
the operation of inductive circuit causes over-voltages ,in particular on opening of the contactor coil. the electromagneticenergy stored in the coil during contactor closing is restored onopening in the form of surges, the voltage wave and amplitude ofwhich may rise to several kilovolts. the electronic e isseriously interfered, and even some sensitive components andcontact point of contactor is broken.ptc suppressor connects withthe contactor coil with parallel connection, which can andeffectively reduced over-voltage wave,control relativeuency ,protect the electronic e and contact point ofcontactor.
