Abstract

The invention provides an insulating pull rod for high-voltage switchgear. The insulating pull rod comprises an insulating tube body and two metal joints; the two ends of the insulating tube body are respectively inserted into the two metal joints, and an annular shielding gap is formed between each metal joint and the insulating tube body at the periphery of the insulating tube body and is used for shielding discharge between the insulating tube body and the metal joints. According to the insulating pull rod, the annular shielding gaps are formed between the metal joints and the insulating tube body and at the periphery of the insulating tube body, so that the discharge between the insulating tube body and the metal joints is shielded, and the partial discharge of the insulating pull rod, especially the joint of the metal joint and the insulating tube body, is avoided; therefore, the electric field uniformity of the insulating pull rod is ensured, the insulating property of the insulating pull rod is further ensured, and the insulating pull rod can work safely and reliably.

Description

technical field [0001] The invention relates to the technical field of composite insulating materials and high-voltage switches, in particular to an insulating tie rod for high-voltage switchgear. Background technique [0002] The insulating rod is a key part of the high-voltage switchgear, which is used to transmit the movement from the grounding part to the insulating member of the high potential part to realize the on-off of the electrical connection. The structure of the insulating rod is thin and long, and it bears certain tensile and compressive loads and instantaneous operating impulse voltage during the opening and closing operation of the circuit breaker, so it is required to have excellent mechanical and electrical properties. [0003] However, at present, discharges are likely to occur between the live part and the insulating part on the insulating pull rod, which affects the electrical performance of the insulating pull rod and causes a safety risk when the insul...
