Abstract

An extra conducting spring element will be added within a medium voltage separable connector system. An extra current path will be created which will lead to a more efficient current distribution throughout the connector system. Temperature rise at hot spots will decrease and vulnerable components will be protected.

Extra spring element for optimizing current flow through medium voltage separable connector system

An extra conducting spring element will be added within a medium voltage separable connector system. An extra current path will be created which will lead to a more efficient current distribution throughout the connector system. Temperature rise at hot spots will decrease and vulnerable components will be protected.

Background

Some medium voltage cable accessories include passive elements that are vulnerable to elevated temperatures. The most critical test for temperature rise is the short-circuit current test. The temperature during this test may not exceed 140°C.

Adding a conducting spring element inside the connector system will create an extra current path. The critical bottleneck at the multi-contact lamella shaped contacts inside the connector system can be relieved by adding an extra spring element. The temperature load at the hot spots and the total connector system will be lowered.

Description

A separable connection system for a medium voltage cable application can be seen in picture 1.

The cable will be terminated to the connector. The metal sleeve establishes a separable interconnection between the two cable ends.

The electrical interconnection between the connector and the metal sleeve will be established by means of multi-contact lamella shaped contacts inside the metal sleeve.
