Description

Technical Field

[0001] The invention belongs to the technical field of power transmission and distribution equipment, and in particular relates to a high-voltage switch cabinet conductor assembly for installing a zero-sequence current transformer. Background Art

[0002] The zero-sequence current transformer is an item used in the power industry. It is a single-turn through-type current transformer, generally used in conjunction with power protection equipment such as small current grounding line selection devices, microcomputer detuning devices, etc. When the power system generates zero-sequence grounding current, it is used in conjunction with relay protection devices or signals to activate the device components to achieve protection or monitoring. When an electric shock or leakage fault occurs in the circuit, the secondary side of the transformer outputs zero-sequence current, causing the equipment protection on the connected secondary line to operate (cut off power, alarm, etc.).

[0003] The zero-sequence current transformer is installed on the three-phase line of the high-voltage switchgear. When an electric shock or leakage fault occurs in the power transmission and distribution circuit system, the three-phase load of the line is unbalanced, and the secondary side of each zero-sequence current transformer outputs zero-sequence current to the corresponding measurement or protection device, so that the components on the secondary line send out circuit cutting and alarm signals, and the operator takes timely action to ensure the safety of people and equipment.

[0004] The existing zero-sequence current transformer is fixed on the side wall of the high-voltage switch cabinet, and the busbar is passed through the inner hole of the zero-sequence current transformer. The existing zero-sequence current transformer is insufficient in terms of insulation convenience. At the same time, the connection position is generally exposed, and there is no separation between adjacent connection positions, which may cause unnecessary dangers during use.
