Latest Patents

One of Tamura's latest patents is for a gas insulated interrupter. This innovative device features a puffer-type gas insulated interrupter that includes stationary and moving main contacts, as well as stationary and moving arc contacts designed for discharging an arc. The interrupter is equipped with a puffer cylinder that plays a crucial role in electric arc suppression. During current interruption, the puffer cylinder moves in conjunction with the moving arc contact to blow electric insulation gas towards the arc formed between the stationary and moving arc contacts. The gas flows between the arc contacts and is subsequently discharged through a gas discharge passage. A duplex puffer chamber is integrated into the gas discharge passage near the moving arc contact, which holds the insulation gas and causes it to be heated and pressurized by the arc. This gas is then expelled towards the stationary arc contact, effectively suppressing the arc. The collaboration of gas flow from the duplex puffer chamber and the puffer cylinder allows for a reduction in gas pressure within the puffer cylinder, thereby decreasing the operating force required for the interrupter.
