conductor connection device

Abstract

[Problem] When conductors are connected to one another, conventionally the conductors are plated with silver or tin, which are conductive and corrosion resistant, in order to prevent the formation of oxide films on the surface of the conductors, and to prevent electrolytic corrosion resulting from different types of metal coming into contact with one another. Plating the entire conductor results in an increase in cost, and partial plating requires the addition of a masking operation, and depending on the shape of the conductor, may result in a cost that is higher than coating the entire conductor. [Solution] According to the present invention, when conductors are to be connected using a fastener, an electrically conductive member for connection of conductors is interposed between the two conductors. A plurality of protruding portions are formed on the surfaces, of the electrically conductive member for connection of conductors, that come into contact with the conductors. A plating layer is formed on the contacting surfaces that include the protruding portions, by means of an electrically conductive and corrosion-resistant plating process. When the conductors are connected to one another using a fastener, the contact pressure of the protruding portions causes oxide films on the electrically conductive member for connection of conductors to be removed.

Description

technical field [0001] The present invention relates to conductor connection, in particular to a conductor connection device installed in a metal-enclosed switchgear for supplying power to power stations, substations, factories and the like. Background technique [0002] The metal-enclosed switchgear that constitutes the existing power distribution equipment is configured as follows Figure 15 The main bus conductor 9 and the branch bus conductor 10 shown are conductors for supplying current, and their function is to obtain power from the outside or supply power to loads through these conductors. The electric power obtained from the external cable 11 used to introduce electric power flows through the branch bus conductor 10, and flows to the main bus through a switching device such as a circuit breaker for blocking current, a current transformer or a measuring transformer such as a zero-phase current transformer. Conductor 9. The power flowing through the main bus conductor...

AI Technical Summary

Problems solved by technology

However, due to the high cost of plating the entire conductor, and the need for masking when partial plating is performed, the cost may be higher than the overall plating cost depending on the shape of the conductor

In addition, depending on the conductor material, there may be a property that plating is difficult to adhere to due to the oxide film formed on the conductor surface

Therefore, the cost of plating the conductor is high, and it also has the disadvantage that sometimes the yield of the component may be reduced due to the above-mentioned properties
