CONTACT MELTING DEPTH AS A FUNCTION OF ENERGY AND HEAT PHYSICAL PARAMETERS OF CONTACT MATERIAL
Journal Title: Енергетика і автоматика - Year 2018, Vol 0, Issue 6
Abstract
The contacts of the PML starters with a current load of 4; 6.3; 10A. In the course of research, contact-parts of starter actuators made of serial contacts on the basis of silver and environmentally friendly research contacts on the basis of copper were used. The formula for determining the value of the depth of melting at a single switching current is given. The electric arc (the time of its burning) is directly related to the electroresive phenomena (the depth of the contact's melting point). The formula for determining the depth of the melting is obtained by solving the heat equation with the account of the limiting conditions of the second kind and the depth of the melting with the energy and thermophysical parameters of the contact material.
