INSULATING SWITCHING ROD WITH A CONTACT PRESSURE ARRANGEMENT COMPRISING A PLURALITY OF HELICAL COMPRESSION SPRINGS WOUND IN OPPOSITE SENSES |
摘要 |
<p>An insulating switching rod is used to initiate a drive movement into a moving contact of an electrical contact system of a switching device and to produce a contact force when the contact system is in the closed state. A tensioning apparatus is arranged in a cavity for a drive element of the switching rod in order to maintain the contact force, which has a greater contact force with a compact design, and ensures constant spring characteristics as well as low wear over the entire useful life. The tensioning apparatus is formed by a helical compression spring configuration or by two oppositely wound helical springs.</p> |
