The utility model discloses a horizontal setting double breaking port vacuum breaker used for eclectic power locomotive, including switch body and upper cover, switch inner center insulated pull-rod. Two vacuum suppressing arc chambers are positioned in the upper horizontal symmetry of the switch body. An inputting line is provided with a terminal of the vacuum suppressing arc chamber, and outputting line is deduced by a terminal of other vacuum suppressing arc. The connection between two of the vacuum suppressing arc chamber is by electric soft connection line, comprising double breaking port leading electric loop switch. The upper part of the insulated pull-rod connects with the left vacuum suppressing arc chamber and right vacuum suppressing arc through horizontal plate and the buffer spring, buffer spring seat, lateral upright turning arm, lateral horizontal arm, turning square axes, lateral active contact head pull-rod. The lower part of the insulated pull-rod has permanent magnetism structure through the connecting franc disk. Through various experiments, it proves that it is small size, light weigh, simple structure advantages. All the parts can be conveniently tested, checked and replacing, is a new model of the horizontal setting double breaking port vacuum breaker for electric power locomotive.
