Abstract

The invention discloses a heat-resisting bus duct which comprises a bus duct casing, wherein a heat-resisting coating is arranged outside the bus duct casing; the heat-resisting coating is 20-35mm thick, wherein the heat-resisting coating consists of the following components in parts by mass: 25-45 parts of an acrylic emulsion, 17-25 parts of ammonium polyphosphate, 3-15 parts of melamine, 6-12 parts of pentaerythritol, 1-5 parts of chlorinated paraffin cobalt, 3-8 parts of titanium dioxide and 2-3 parts of a P-19 thickening agent. The bus duct disclosed by the invention, which is prepared from a fire retardant coating, can be effectively prevented from being melted at a high temperature, so as to avoid the occurrence of bus explosion in the case of electric short circuit, and the bus duct can improve safety and wear resistance as well as wide fire resistance and solvent resistance; and the bus duct is excellent in construction property under various atmospheric environment conditions.

Description

technical field [0001] The invention relates to the field of power transmission, and more specifically, to a heat-resistant busway. Background technique [0002] Modern high-rise buildings and large workshops require huge amounts of electrical energy, and in the face of the huge loads requiring hundreds of thousands of amperes of strong current, safe and reliable conduction equipment must be selected. Busway is mainly used in the ambient temperature of -20 0 C to +40 0 Between C, the relative humidity of the atmosphere is not more than 90%, the altitude is not more than 2000 meters, the rated voltage is above 10KV, and the frequency is 50-60HZ for large-scale power transmission and distribution systems, because the traditional busway is easy to melt when exposed to high temperature. It will lead to short circuit or explosion of the whole system; therefore, designing a heat-resistant busway is an urgent problem to be solved by those skilled in the art. Contents of the inv...
