Problems solved by technology

In order to prevent phase-to-phase short circuit in the bus duct, it is often necessary to fill the current-carrying conductors with insulating material, but in actual use, the damage of the insulating material often causes phase-to-phase short circuit, which brings certain safety hazards, especially when working under high voltage. The performance is lower, so the compressive strength of the existing busway is usually lower
At the same time, the busway shell in the prior art is usually a metal shell. Since the expansion coefficient of the metal shell is different from that of the conduc...

Abstract

The invention discloses a high-voltage resistant waterproof bus duct for wind power/nuclear power/water power and a manufacturing method thereof, the bus duct comprises bare buses and composite resin bodies which are poured and wrapped on the peripheries of the bare buses, wherein the bare buses are mutually separated by the composite resin bodies, the bus duct is a whole formed by curing the bare buses and the composite resin bodies, and the bus duct does not need a metal housing. As the bare buses of the bus duct are separated by the composite resin bodies with very high insulating property, the bus duct can avoid the interphase short circuit, thereby improving the safety performance of the bus duct, leading the withstand voltage strength of the bus duct to be very high, withstanding the voltage of 35kV and protecting the safety of the bus duct during the high-voltage work. Simultaneously, as the composite resin bodies have very strong water resistance and corrosion resistance, when the bus duct works underwater for a long time, the bus duct can not be corroded, thereby better protecting a current-carrying conductor in the housing and further ensuring the normal production for power supply.

Description

technical field [0001] The invention belongs to the technical field of power transmission and distribution equipment, and in particular relates to a high-voltage resistant waterproof busway for wind power / nuclear power / hydropower and a manufacturing method thereof. Background technique [0002] The bus duct is also called the bus trunk system, which is a necessary device for inputting power to the building. The bus duct is usually composed of a current-carrying conductor, a housing and insulating materials between conductors. In order to prevent phase-to-phase short circuit in the bus duct, it is often necessary to fill the current-carrying conductors with insulating material, but in actual use, the damage of the insulating material often causes phase-to-phase short circuit, which brings certain safety hazards, especially when working under high voltage. The performance is lower, so the compressive strength of the existing busway is usually lower. At the same time, the busw...
