Embodiment 1

[0026] Embodiment 1: A high heat dissipation full resin cast busway, such as Figure 1-3 As shown, it includes a closed casing 1, and a plurality of bus conductors 11 and composite resin bodies 12 located in the closed casing 1, each bus conductor 11 is wrapped by a composite resin body 12, that is, adjacent bus conductors 11 are composited The resin body 12 is separated to prevent short circuit, the protection grade is IP68, and has the functions of waterproof, fireproof, anticorrosion and explosion-proof.

[0027] A heat conduction block 2 in contact with the composite resin body 12 is arranged on the top of the closed shell 1. The heat conduction block 2 is made of heat conduction silicone grease, and a plurality of heat sinks 3 are evenly distributed on the heat conduction block 2. The heat of the composite resin body 12 is transferred to the heat conduction Block 2, and then dissipate heat through cooling fins 3, so that the heat in the closed casing 1 can be dissipated i...

Embodiment 2

[0035] Example 2: A high heat dissipation all-resin cast busway, the difference from Example 1 is that the high temperature resistant layer includes the following components by weight: EPDM raw rubber: 55kg, silicone resin: 32.5kg , glass fiber 6.5kg, diaminodiphenyl sulfone 5.5kg, dimethyl polysiloxane solution 13kg, epoxy resin 34.5kg, aluminum powder 6kg, high wear-resistant carbon black 8kg, phosphate 2.5kg, modified clay 5kg, mica ceramics 7kg.

[0036] The preparation method of the high temperature resistant layer comprises the following steps:

[0037] a. Add EPDM raw rubber, silicone resin and epoxy resin to the planetary ball mill together, add grinding balls according to the ratio of ball to material (1-3):1, then add glass fiber, glass fiber The amount is 45-50% of the mass of the grinding balls, ball milling at a rate of 300-350 rpm for 2-2.5 hours, and after the ball milling is completed, place it in a drying oven at 350-400°C for 0.5-1 hour to obtain a dry powder;...

Embodiment 3

[0040] Embodiment 3: A high heat dissipation all-resin cast busway. The difference from Embodiment 1 is that the high temperature resistant layer includes the following components by weight: EPDM raw rubber: 60kg, silicone resin: 35kg, Glass fiber 8kg, diaminodiphenyl sulfone 6kg, dimethyl polysiloxane solution 14kg, epoxy resin 35kg, aluminum powder 7kg, high wear-resistant carbon black 9kg, phosphate 4kg, modified clay 6kg, mica ceramics 8kg .

[0041] The preparation method of the high temperature resistant layer comprises the following steps:

[0042] a. Add EPDM raw rubber, silicone resin and epoxy resin to the planetary ball mill together, add grinding balls according to the ratio of ball to material (1-3):1, then add glass fiber, glass fiber The amount is 45-50% of the mass of the grinding balls, ball milling at a rate of 300-350 rpm for 2-2.5 hours, and after the ball milling is completed, place it in a drying oven at 350-400°C for 0.5-1 hour to obtain a dry powder; ...

Abstract

The invention discloses a high-heat-dissipating all-resin casting type busbar groove, A technical field of bus slot is disclose, include a closed housing, and a plurality of busbar conductors and a composite resin body located in the enclosed housing, Each busbar conductor is wrapped by a composite resin body, and a heat conduction block contacting with the composite resin body is arranged above the enclosed shell, the width of the heat conduction block is gradually reduced from one end close to the enclosed shell to the other end, a plurality of heat sink fins are uniformly distributed on theheat conduction block, and the length direction of the heat sink fins is perpendicular to the length direction of the heat conduction block. The scheme can guarantee the heat dissipation effect of the bus slot.

Description

technical field [0001] The invention relates to the technical field of bus ducts, in particular to a high heat dissipation full resin cast bus duct. Background technique [0002] Modern high-rise buildings and large workshops require a huge amount of electric energy, and in the face of the huge loads requiring hundreds of thousands of amperes of strong current, it is necessary to choose safe and reliable conduction equipment, and the busbar system is a good choice. The busway system is a power distribution device for efficient current transmission, especially to meet the needs of economical and reasonable wiring of increasingly taller buildings and large-scale factories. [0003] The busway was developed by the United States. It uses copper or aluminum as a conductor, supports it with non-olefinic insulation, and then installs it into a metal groove to form a new type of conductor. The real practical application in Japan was in Showa 29, and the busway has been developed si...
