The invention discloses a 1 / 2 drawer unit of a drawer type power distribution cabinet. The 1 / 2 drawer unit comprises a drawer body and a plurality of primary movable inserts and secondary movable inserts. The drawer body comprises a drawer panel and drawer lateral boards on two sides. Every primary movable insert comprises an inserting type switch body, a switch base and a switch base installation frame, wherein the switch base installation base is arranged in the middle of a power distribution cabinet framework, and the bottom of the drawer body is supported on a separation board of a drawer layer through a plurality of guide rails. The secondary movable inserts are nine-needle connectors arranged in the inserting type switch bodies, primary plugs on the inserting type switch bodies are respectively inserted into corresponding sockets on the switch base, and inserting needles of the nine-needle connectors are inserted into corresponding jacks on the switch base. The maximum current capacity of the 1 / 2 drawer unit is improved to 250A, so that requirements for exchanging of the drawer type power distribution cabinet are met. The primary movable inserts and the secondary movable inserts of the inserting type switch body are reliable and accurate in contact, and the radiating effect is good.

The invention discloses a protective hood for a refrigerator compressor. The protective hood sleeves the inner casing part of a black box of the compressor and comprises an open cuboid-shaped casing, wherein the casing comprises two narrow surfaces, two wide surfaces and a bottom surface; a vertical equipment groove is formed in at least one narrow surface, and a heat dissipation window is arranged on at least one wide surface; and the outside of each heat dissipation window is connected with a water-proof membrane, and the inner surface of each heat dissipation window is connected with a heat dissipation net. Through the use of the protective hood disclosed by the invention, the situation that when the compressor is opened to perform repair or routine maintenance, a water drop or filth outside the black box enters the inner part of the compressor so that unnecessary damage is caused to the compressor is prevented, the routine maintenance property and the repair property of the refrigerator compressor are improved, and the service life of the compressor is prolonged.

The invention discloses a power variable stay cable permanent magnet eddy current retarder and belongs to the field of bridge structural vibration control. The power variable stay cable permanent magnet eddy current retarder comprises a rigid shaft, a second linear movement mechanism, a fixed disc, a conductor disc, a driving gear, at least three driven gears of different radiuses, and at least one pair of permanent magnets opposite in magnetic poles; one end of the rigid shaft is connected with the second linear movement mechanism, and the other end of the rigid shaft sequentially penetratesthrough the fixed disc, the conductor disc and the driven gears; the fixed disc is fixed relative to the rigid shaft, the conductor disc is fixed relative to the driven gears, and the driven gears areconnected with the rigid shaft through bearings; the permanent magnets are arranged on the surfaces of the fixed disc. According to the power variable stay cable permanent magnet eddy current retarder, the conductor disc moves inside the magnetic field of the permanent magnets to cut magnetic lines to produce eddy current damping and accordingly to dissipate vibrating energy of a stay cable and inhibit vibration of the stay cable; through engagement between the driven gears different in radius and the driving gear, the energy consumption power can be adjust, high adaptability to external loadcan be achieved, and the power variable stay cable permanent magnet eddy current retarder can be in an optimum load operating sate for a long time.

The invention discloses a heat radiation structure of twisting cables of a wind generating set. The heat radiation structure of twisting cables of a wind generating set includes a cable harness and a plurality of supporting rings, wherein the cable harness stretches to the inside of a tower tube from a cabin of a wind generating set; the plurality of supporting rings are arranged on cables in the cable harness in the axial direction at intervals, and separate the adjacent cables so as to form a heat radiation space in the cable harness. By setting the supporting rings on the cables, the heat radiation structure of twisting cables of a wind generating set utilizes the supporting rings to separate the adjacent cables so as to guarantee that the cables in the cable harness can have enough heat radiation space and setting of the supporting rings on the cables has little influence on twisting of the cable harness. The heat radiation structure of twisting cables of a wind generating set has the advantages of being simple in structure, being reasonable in design, being safe and reliable, being conductive to heat radiation and twisting of twisting cables of the wind generating set, being conductive to reduction of the cost and the installation difficulty of the cables, being high in practicality, and being substantial in economic benefits.
