Abstract

The invention provides a phase-shifting transformer throat-knot ascending flanged base anti-leakage structure which comprises a throat-knot ascending flanged base, a fastener, a connecting piece and a sealing washer, the throat-knot ascending flanged base is of a round pipe structure with flanges at the two ends, the sealing washer is assembled between the flange of the throat-knot ascending flanged base and the corresponding flange for sealing, and the flange is fastened through the fastener. And the two ends of the connecting piece are respectively connected with the flange of the throat knot ascending flanged base and the corresponding flange of the throat knot ascending flanged base. The sealing structure can protect a fastener at the joint of the throat-knot ascending flanged base of the phase-shifting transformer from being loosened due to vibration of the transformer, so that the sealing effect is not affected.

Description

technical field [0001] The invention belongs to the technical field of power transmission and transformation, and in particular relates to an anti-leakage structure and an installation method for a riser seat of a phase-shifting transformer Adam's apple. Background technique [0002] In the environment of UHV AC / DC hybrid connection, large-scale new energy centralized access, etc., the power flow of the power grid has great randomness in the distribution of time and space, which increases the difficulty of regulation and control, which will inevitably cause the power flow channel of the power grid to be blocked and affect the transmission network. Power transfer efficiency. [0003] The installation of power flow control devices such as phase-shifting transformers in the large power grid can effectively improve the transmission capacity of key sections, control the power flow distribution of the power grid, alleviate the unbalanced power flow, ensure the smooth flow of the A...
