The invention provides a sound insulation material (10) capable of improving the sound insulation performance, which comprises a sound insulation board (20) throughout the whole surface, a sound-source perforation board (30) arranged closer to the sound source (2) than the sound insulation board (20) and equipped with through holes (31) for sound absorption and a radiation perforation board (40) at the opposite side of the sound source (2) separated by the sound insulation board (20) and equipped with a plurality of through holes (41) for lowering the radiation sound.The sound insulation board (20) has the shape of reciprocating between the two perforation boards (30, 40).A sound-source air layer (50) and a radiation air layer (60) are respectively formed between the sound-source perforation board (30) and the radiation perforation board (40).A plurality of sound-source joint parts (21) and a plurality of radiation joint parts (22) respectively bonded to the two perforation boards (30, 40) are alternately provided.

The invention discloses a crack-self-healed dismounting-free insulation system and a preparation method thereof. The insulation system comprises an inner bonding fireproof layer, a heat insulation layer, an outer bonding fireproof layer, a reinforcement layer, an anti-cracking layer and a fixing member which is connected with an exterior wall, wherein rib reinforcements which are of dot-matrix arrangement are arranged between the bonding fireproof layers and the heat insulation layer. Through embedding self-healed capsules, which contain healing matrix materials, into one or more of the outer bonding fireproof layer, the inner bonding fireproof layer, the reinforcement layer and the anti-cracking layer, by virtue of the performance that the self-healed capsules automatically rupture under tension deformation and/or stress deformation and/or certain humidity and temperature change range, the healing matrix materials inside the self-healed capsules can overflow and automatically permeate to cracks or tensile damage points of the insulation system, so as to carry out healing repair. The insulation system can be applied to construction engineering construction, can be used for solving the problem of difficulty in heat insulation of the exterior wall, can replace a formwork and can automatically carry out healing repair when the insulation system encounters early-stage common problems, such as crack falling.

The invention belongs to the technical field of power equipment insulation, and particularly relates to a defect feature detection platform for a power distribution insulator and an electrical insulation system around the power distribution insulator. A test wire is arranged at the upper parts of two wire fixing and supporting parts, one side of each of the two wire fixing and supporting parts isprovided with an ultrahigh frequency sensor fixing and supporting part, and the other side of each of the two wire fixing and supporting parts is provided with an ultraviolet imager fixing and supporting part; an insulator fixing and supporting part is arranged on the lower portion of the middle position of the two wire fixing and supporting parts, and a replaceable test insulator is connected between the upper portion of the insulator fixing and supporting part and the test wire. The platform is simple in structure, reasonable in design and simple to use and operate, and is used for realizingdetection test research on defects and field intensity influence. The fixed observation of the ultrahigh frequency and ultraviolet imager can be realized only by replacing different defective insulators and adjusting the height of the insulator fixing and supporting part, so that the characteristic quantities detected by different types of defects are kept under the same observation condition, and the comparability of data is ensured.
