    摘要: A multi-functional automatic switching circuit for direct current ice melting and a switching method thereof are provided. The automatic switching circuit comprises at least one sub-switching circuit. The sub-switching circuit comprises a six-pulse current converter (R) with no saturable reactor, six reactors (L1a, L1b, L1c, L2a, L2b, and L2c), three three-phase knife switches (Sac1, Sac2, and Sac3), and five single-phase knife switches (SV1, SV2, SV3, SV4, and SV5). The sub-switching circuits in series connection or parallel connection, four direct current side switching knife switches (Sdc1, Sdc2, Sdc3, and Sdc4), an isolation knife switch (K), a breaker (QF) and a control and protection system (CP) may form an automatic switching circuit for six-pulse or twelve-pulse direct current ice melting. The automatic switching circuit with no saturable reactor reduces noise during operation, achieves mutually automatic switching among modes of reactor switching, ice melting and test, and may complete the through-flow test of the automatic switching circuit without switching in a power transmission line, thereby solving the problem of daily operation and maintenance.

    摘要: An insulator is disclosed, which includes an insulating surface. A part of the insulating surface is applied with a conductive coating having a specific resistivity. A conductive coating region having the specific resistivity and a nonconductive coating region are configured that: in a dry environment, no continuous conductive channel exists between upper and lower fittings of the insulator. The value of the leakage current that can be caused by the conductive coating region having the specific resistivity on the insulating surface enables the insulating surface to reach an ice-proof temperature in an icing climate condition. Also, a power transmission apparatus in which the insulator is adopted is disclosed. In an icing climate condition, the conductive coating can achieve the function of increasing the value of the leakage current on the surface of the insulator, so as to prevent the ice formation.
