Abstract

A disconnector to reduce considerably high voltage and high frequency current generated during the service no-load opening and closing,

the disconnector comprising a first main contact a second main contact, a sliding contact and an arcing horn having a length,the disconnector having a connected state, an intermediate state and a disconnected state, whereinin the connected state a first electrical contact is established between the first main contact and the second main contact,in the intermediate state the first electrical contact is interrupted while a second electrical contact exists between the sliding contact and a contact position on the length of the arcing horn, andin the disconnected state the first electrical contact and the second electrical contact are interrupted, whereinat least a part of the length of the arcing horn comprises an electrical filter configured to provide a resistance and an inductance to an electrical current.
