Problems solved by technology

After installing voltage equalizing rings at both ends of the composite insulator, although the unevenness of the electric field distribution can be effectively improved, 40% of the insulation length still does not work, so the electric field intensity at the high voltage end of the composite insulator is still very hi...

Abstract

This invention relates to a high voltage electricity transmission equipment technology especially referring to a capacitance voltage-sharing rod suspension complex insulator including an insulator with voltage-sharing rings on metals at its both ends, voltage-sharing pieces between the rings to utilize a main capacitance between the voltage sharing pieces and between the pieces and the rings to increase, the main capacitance between the main insulators of the combined insulators to reduce influence to the field distribution generated by the combined insulators, steel towers and wires, thus the insulators distributed evenly in axial field to eliminate corona or flashover.

Description

Technical field: [0001] The invention relates to high-voltage power transmission equipment technology, in particular to a capacitor voltage equalizing rod-shaped suspension composite insulator. Background technique: [0002] With the rapid development of the power industry, the power sector has built many important high-voltage, large-capacity, long-distance transmission lines. On these high-voltage transmission lines, the transmission wires rely on porcelain insulators, glass insulators, porcelain rod insulators and The rod-shaped suspension composite insulator is suspended on the iron tower. The safe and reliable operation of these insulators is the key to the safety of transmission lines. And existing porcelain, glass insulators are connected in series one by one to suspend transmission lines, and both ends of monolithic porcelain and glass insulators have iron caps and steel feet. The main capacitance of each piece is formed between the iron cap and the steel feet. In ...
