The invention provides a method for acquiring filtering coefficient, and a torque filtering method and system for a hybrid power vehicle. The method for acquiring the filtering coefficient includes: acquiring current working condition modes of an engine, a first electric motor and a second electric motor, determining a filtering coefficient of the engine, a filtering coefficient of the first electric motor and a filtering coefficient of the second electric motor according to the current working condition modes of the engine, the first electric motor and the second electric motor; acquiring a larger value from the filtering coefficient of the first electric motor and the filtering coefficient of the second electric motor, comparing the larger value and the filtering coefficient of the engine to acquire a smaller value from the larger value and the filtering coefficient of the engine, and using the smaller value as a final torque filtering coefficient; and finally performing first order inertia filtering according to the final torque filtering coefficient. The final torque filtering coefficient can be determined by compressive consideration of the filtering coefficients of the engine, the first electric motor and the second electric motor in the current working conditions; a current output torque of the whole vehicle can follow the desired torque of a driver timely and accurately, and the demand of a hybrid power automobile for torque filtering can be met.

The invention provides an automatic return door hinge, wherein through the mutual matching of a damping part and a return automatic hinge, when the refrigerator is being closed, the two wedges of a first mounting plate and a second mounting plate are mutually matched to form automatic return, a hollow guide pipe drives a first sleeve to rotate relative to a second sleeve, so as to enable the damping grease between the first and the second sleeves to generate extrusion, as the viscous action of the damping grease blocks the relative motion between the first and the second sleeves to supply the damping buffer action, so that the serious collision between the refrigerator door and the refrigerator body caused by overhigh speed of the automatic closing of the refrigerator door is effectively avoided, and the service life and the using comfort of the refrigerator are effectively improved.

The provided alarm process method comprises: A. receiving alarm message from RNC; B. deciding whether the message fit to pre-set conditions; and C. controlling the alarm message flow according to decision result. This invention avoids serious impact on BAM, and controls the damage in an acceptable range.

The invention discloses an air return energy-saving device for a fan. The device comprises an air return box, a mounting shell is connected to the surface of one end of the air return box, a net rackis arranged at the end of the mounting shell, a filtering isolation plate is connected to the inner side of the net rack, mounting blocks are fixed to the two sides of the net rack, storage grooves are formed in the bottoms of the mounting blocks, fixing plates are arranged in the storage grooves, and fixing blocks are connected to the two sides of the outer wall of the mounting shell; according to the invention, the designed fixing plates can be quickly clamped into the fixing grooves of the fixing blocks, so the filtering isolation plate can be quickly mounted and limited, and the situationthat a traditional mounting mode is too complex and prone to deviation is avoided; by means of the designed fixing blocks, the designed fixing blocks and the mounting blocks are attached to each other, so mounting of the filtering isolation plate is limited, and springs and the designed fixing plates are mounted and supported by means of the designed sliding rods.

This invention relates to reclosing method for power transmission line. For joint parallel double circuit type: each circuit being equiped with individual protector, main protection being phase-splitting current differential protection or phase-command longitudinal protection; for various type single circuit fault or overline fault withni a zone, tripping fault being detected, determinnig no serious permanent fault, sequentially reclosing the tripping phases. For double-circuit fault, there must be two different type circuit being of no fault for reclosing, if not, two circuits must be tripped-off. This invention method increases the reclosing rate, together with minimizing the shock to the system after reclosing permanent fault.
