直流融冰切换装置
摘要：
本实用新型涉及一种直流融冰切换装置，它包括三个隔离开关，第一个隔离开关的一端接三相输电线路的一相，第二个隔离开关的一端接三相输电线路的第二相，它们的另一端一起接直流融冰电源的一极，第三个隔离开关接在三相输电线路的第三相和其它两相任意一相之间，该直流融冰切换装置还设有另外两个隔离开关，第四个隔离开关的一端接第二个隔离开关与三相输电线路的第二相相连的一端，第五个隔离开关的一端接第三个隔离开关与三相输电线路第三相相连的一端，它们的另一端一起接直流融冰电源的另一极；主要用来解决现有的直流融冰切换装置在对较长线路进行融冰时不能对每相都进行切换来完成融冰的问题。
摘要（英）：

The utility model relates to a DC ice melting switching device, which comprises three isolating switches, wherein one end of a first isolating switch is connected with one phase of a three-phase transmission line; one end of a second isolating switch is connected with a second phase of the three-phase transmission line; the other end of the first isolating switch and the other end of the second isolating switch are connected with one pole of a DC ice melting power supply; a third isolating switch is connected between a third phase of the three-phase transmission line and any one of the other two phases; the DC ice melting switching device also comprises other two isolating switches; one end of a fourth isolating switch is connected with the end of the second isolating switch which is connected with the second phase of the three-phase transmission line; one end of a fifth isolating switch is connected with the end of the third isolating switch which is connected with the third phase of the three-phase transmission line; the other end of the fourth isolating switch and the other end of the fifth isolating switch are connected with the other pole of the DC ice melting power supply; and the DC ice melting switching device is mainly used to solve the problem that the prior DC ice melting switching device cannot switch each phase when melting ice in quite long lines.
