4results about How to "Eliminate spacing" patented technology

The utility model discloses a differential control mechanism and contain the winding equipment of this mechanism relates to die cutting machine technical field, including differential control subassembly, the differential control subassembly includes new base paper unwinding roller, and the old base paper recovery roller is arranged in parallel to the new base paper unwinding roller side. This differential control mechanism and contain the winding equipment of this mechanism after material die cutting, and the old base paper of bearing waste material is no longer discarded, but is through the old base paper recovery roller reverse winding, realizes repeated use, and simultaneously synchronous new base paper is put, and the finished product material after die cutting is stripped from the old base paper, and is directly transferred to the new base paper surface, and is completed finished product winding by forming winding roller, and the new technical scheme of this die cutting device realizes the saving of raw material paper and mould spacing through the collaborative design of recovery base paper, differential control and material transfer, and its core principle is to utilize differential ratio to eliminate the material spacing in traditional craft, and simultaneously reduces base paper consumption through the replacement of new and old base paper.

The utility model relates to the technical field of structural design of power equipment, and particularly provides a bus connecting device and a combined cabinet structure, the bus connecting device comprises a bus used for being connected with outgoing line terminals of two adjacent gas-insulated switchgears, and bus cylinders used for being respectively sleeved outside the outgoing line terminals of the two adjacent gas-insulated switchgears, and the bus cylinders are respectively sleeved outside the outgoing line terminals of the two adjacent gas-insulated switchgears. A current transformer is arranged outside the bus, the current transformer is located between the bus cylinders on the two sides, the two ends of the current transformer and the bus cylinders on the two sides are assembled in an inserted and sealed mode, a measuring coil is poured in the current transformer, the current transformer and the bus are integrally formed through pouring, and the space interval between the current transformer and the bus is eliminated. The current transformer is attached to the bus, and the current transformer does not move in the vertical direction under the condition that vibration is generated during opening and closing of the gas-insulated switchgear, so that the sealing and insulating effects of the current transformer and the plugging and sealing assembly positions of the bus cylinders on the two sides are good, and the leakage of insulating gas is avoided.
