A THREE PHASE GAS-INSULATED PATCHBOARD CONNECTION MODULE AND A GIS SWITCHGEAR

INSTALLATION USING THE SAME

Technical Field

The present invention relates to an electrical connection module, particularly to an electrical connection module used in a gas-insulated, metal-enclosed, and high-voltage switch to connect one three-phase conductor to multiple three-phase conductors. The present invention further relates to a gas- insulated, metal-enclosed, and high-voltage switch that uses the aforesaid electrical connection module.

Background Art

In a high-voltage switch, an electrical connection module can be used to connect one three-phase conductor to multiple three- phase conductors. For example, an electrical connection module that works in one-input and two-output mode can input one channel of three-phase alternating current and output said three-phase alternating current as two channels of three-phase alternating currents.

Said electrical connection module comprises an encapsulation can, three conductors, and three patch boards. The encapsulation can is used to encapsulate the conductors. Each conductor corresponds to one phase of the three-phase conductors, and each conductor is provided with three connecting plugs. The patch boards are used to connect the conductors to the three-phase AC line outside the encapsulation can. Each patch board is provided with three connecting ports, and each connecting port is connected to the connecting plug of a conductor. With an electrical connection module provided in prior art, the positions of the connecting ports corresponding to respective conductors on each patch board are fixed. When the positions of the connecting ports corresponding to respective conductors need to be adjusted on the patch boards, each of the conductors having complex structures need to be replaced accordingly. Consequently, the costs in using a high-voltage switch increase greatly. Moreover, conductor replacement is complex.
