In one aspect of the embodiments of the present invention, there is provided a disconnecting switch, including: the bus structure comprises a shell 01 and at least two phases of bus mechanisms arranged on the shell 01, wherein each phase of bus mechanism is also connected with a wiring bar, and the at least two phases of wiring bars are arranged on the same side of the shell 01 in a step shape.

For example, as shown in fig. 1, the at least two-phase bus bar mechanism may be disposed on the housing 01, for example, inside the housing 01, and can provide better electrical isolation while being protected by the housing 01. In order to meet the wiring requirements of the isolating switch, a corresponding wiring bar can be arranged on each phase bus mechanism, one end of the wiring bar can be connected with the corresponding bus mechanism when the wiring bar is arranged, the other end of the wiring bar can extend to the outside of the shell 01 from the inside of the shell 01, therefore, the convenience of wiring by using the isolating switch is improved, and the other end of the wiring bar can also be located inside the shell 01 without extending out of the shell 01. Meanwhile, in order to facilitate wiring, the corresponding connection lines of each phase of bus mechanism can be arranged on the same side of the housing 01. The wiring rows arranged on the same side can be sequentially arranged in a step shape, namely different phase wiring rows are arranged at different heights, so that the distance between adjacent phase wiring rows is effectively increased, and the electrical isolation performance is improved under the condition that the size of the isolating switch is not increased.

The number of the bus bar mechanisms can be reasonably set according to the requirement of the number of phases actually used by the isolating switch, for example, two phases are set, three phases are set, and the like.

As shown in fig. 1 and 2, a first phase bus mechanism, a second phase bus mechanism, and a third phase bus mechanism are provided in the housing 01 to constitute a three-phase circuit. A first phase wiring bar 110 is connected to the corresponding first phase bus mechanism, a second phase wiring bar 120 is connected to the second phase bus mechanism, and a third phase wiring bar 130 is connected to the third phase bus mechanism.

Correspondingly, a contact mechanism (such as a moving contact and a fixed contact which are matched) connected with the bus mechanism can be further arranged in the contact shell 01, a fuse component connected with the contact mechanism can be further arranged in the fuse shell 01, and an operating mechanism connected with the contact mechanism can be further arranged in the operating shell 01. The bus mechanism, the contact mechanism and the fuse mechanism are connected to form at least two phases of conductive loops, the operating mechanism is connected with the contact mechanism, and the contact mechanism can be driven to move by the movement of the operating mechanism so as to realize the on-off of each phase of circuit.
