Abstract

Реферат Спосіб вимірювання контактного натискання замикаючих контактів електромагнітного нейтрального реле залізничної автоматики полягає у подаванні на обмотку реле імпульсу напруги із амплітудою та тривалістю більшою ніж необхідно для надійного спрацювання реле. Далі вимірюють та аналізують часову залежність струму через обмотку реле після закорочування обмотки реле. При цьому, спочатку доводять струм в обмотці до певного для даного типу реле значення. Після закінчення перехідних процесів закорочують обмотку та знаходять за залежністю струму в обмотці реле струм, при якому починається рух якоря реле, за значенням якого обчислюють контактне натискання замикаючих контактів. До того ж, за залежністю струму в обмотці реле після закорочування знаходять інтервал часу між моментами закорочування обмотки та початком руху якоря у зворотному напрямку, за значенням якого обчислюють контактне натискання замикаючих контактів.Summary The method of measuring the contact pressure of the closing contacts of the electromagnetic neutral relay of railway automation is to apply to the relay winding a voltage pulse with an amplitude and duration greater than necessary for reliable operation of the relay. Next, measure and analyze the time dependence of the current through the relay winding after shorting the relay winding. In this case, first bring the current in the winding to a certain value for this type of relay. At the end of the transients, the winding is shorted and the current at which the relay armature begins to move is found by the dependence of the current in the relay winding, the value of which is used to calculate the contact pressure of the closing contacts. In addition, depending on the current in the relay winding after shorting find the time interval between the moments of shorting of the winding and the beginning of the armature in the opposite direction, the value of which is calculated by the contact pressure of the closing contacts.
