The utility model belongs to power transmission and transformation equipment field discloses a closing resistor structure for circuit breaker arc extinguishing chamber, including, two symmetrical support seat, insulating stick, its both ends are inserted into two symmetrical support seat respectively, polytetrafluoroethylene inner cover, its sleeve joint is on insulating stick, resistance string, by a plurality of resistance sheet is in series and is arranged along the axial direction of insulating stick and is formed, one end of resistance string is contacted with polytetrafluoroethylene inner cover, and the resistance sheet of both ends end portion of resistance string is connected with support seat respectively. Because the utility model passes through the polytetrafluoroethylene inner cover of installation between insulating stick and resistance string, can alleviate the collision between resistance sheet and insulating stick when vibrating, thereby avoiding the partial breakage of the inner hole edge of resistance sheet due to operation or transportation vibration, thereby improving product performance, ensuring the safe operation of power grid.

The utility model discloses an electromagnetic heating energy-saving device of a solid tire vulcanizing machine, and relates to the technical field of vulcanizing machines. The heating device comprises a rack, an electric cabinet arranged on one side of the rack and a mold arranged on the inner side of the rack, and further comprises a lower heating seat arranged below the mold on the inner side of the rack. According to the utility model, the protective cover capable of being lifted and opened and closed is arranged, so that a solid tire heating and vulcanizing station can be isolated when the vulcanizing machine works, the safe operation of the vulcanizing machine is prevented from being influenced by the interference of external factors, and meanwhile, safety accidents caused by mistaken touch of operators are prevented; harmful gases such as sulfur dioxide and hydrogen sulfide generated in the vulcanization process can be sucked into the barrel body through the negative pressure fan and are adsorbed and purified by the activated carbon, so that the harmful gases generated during equipment operation are prevented from being directly dissipated into a workshop environment to pollute air and damage health and safety of workers; and therefore, the environmental protection performance of the device during heating and vulcanizing treatment on the tire is effectively improved.
