Embodiment Construction

[0023] In order to make the content of the present invention more clearly understood, the present invention will be further described in detail below based on the specific embodiments and in conjunction with the accompanying drawings.

[0024] Tubular busbar is one of the key equipment in the power transmission and transformation system, and plays a vital role in the safe and reliable operation of the transmission and transformation system and power equipment. Tubular busbar is mainly used in the conductor connection between the power grid transmission wire and the substation transformer in my country's electric power construction projects, the jumper wire in the transmission line, the connecting conductor in the power equipment, and the overcurrent conductor in the high-current DC ice melting device. A new conductor that replaces the traditional rectangular, slotted, bar-shaped busbars and soft wires is one of the key equipment in the power transmission system. At present, the...

Abstract

The invention discloses an all-insulation pouring tubular bus, which relates to the technical field of power equipment and comprises a conductor, a shielding insulating layer coated outside the conductor and an insulating shell coated outside the shielding insulating layer, and a through hole penetrating through the conductor is formed in the conductor along the axis of the conductor. The invention further discloses a preparation method of the all-insulation pouring tubular bus. The insulating shell is formed by pouring various volcanic rock minerals and resin, so that the problems of poor fire resistance, corrosion resistance and aging resistance of an existing insulating material are effectively solved, and the service life of the bus is effectively prolonged.
