Knife Switch Assembly, An Electric Power Distribution Switchgear And A Method For Preventing Electric Discharges

A knife switch assembly comprising a pair of hinged contact knives, arranged parallel to each other and connected to each other at a first respective end, and moveable between at least two positions, and a first electric contact element comprising a current carrying conductor, said contact knives being made of an electrically conductive material and being electrically connected at said first end to a first electric conductor, and further comprising an operator device for moving said pair of contact knives between the at least two positions, of which a first position is an open position in which a respective second end of the contact knives is disconnected from any electrical contact, and a second position is a first contact position in which said respective second end of the contact knives is in electrical contact with the first electric contact element, characterized in that it comprises a guide member located between the two contact knives, said guide member having two projecting side parts, each projecting side part extending along at least part of a respective side of each contact knife , which side faces a corresponding side of the other contact knife, and that said guide member is made of a non-conductive material and has a shape adapted to receive the first electric contact element between the two projecting side parts.
