CONTACT MODULAR TYPE FOR MODERNIZATION Turnout SERIES ELECTRIC DEVICE SP slaked arc discharge in a contact group

摘要

The invention relates to a floor rail means automation and remote control operating mechanisms composed of electric switches, namely a device for switching an electrical circuit in the periods of movements and gate circuit and the control lines of the switch actuator. The task of the claimed technical solution is to increase the safety of trains. In the process solutions of the problem is achieved technical result consists in increasing the service life of the contactor by reducing the burnout material contact elements, except arcing when opening the movable contact pieces and the moving contact elements. Said technical result is achieved contactor modular type for upgrading the switch actuator series JV the device quench arcing contact group consisting of a fixed and movable contact elements, which are fixedly mounted contact parts, during the closure of the movable and fixed contact members there is relative sliding contact -detaley, movable contact elements rests on one side of the resilient coil spring and the other in an elastic flat ruzyne, the rigidity of the coil spring defines the contact force upon contact the contact parts, wherein the elastic coil spring is divided into two parts, the insulating member. In addition, the insulating member is a cylinder with an external shoulder in the middle of the cylinder, the width of the shoulder is 1.3 mm, the cylindrical portion of the insulating member includes an inner cylindrical portion of the spring.
