Embodiment Construction

[0041] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0042] Such as Figures 1 to 14 As shown, a method for replacing the insulating bushing between poles of the collector ring of a generator, it includes the following steps:

[0043] Step 1): Remove part of the tension bolt 3 and the corresponding tension nut 4 between the upper collector ring 1 and the lower collector ring 2, and then place the upper surface of the upper collector ring 1 and the lower collector ring 2 One part of the insulating sleeve 5 on the surface is replaced;

[0044] Step 2): Install the operating screw 6 and the operating nut 7 on the upper collector ring 1 and the lower collector ring 2, and then remove the tension bolt 3 and the remaining part between the upper collector ring 1 and the lower collector ring 2 Tighten the nut 4, and replace the insulating sleeve 5 located on the upper surface of the upper col...

Abstract

The invention discloses a replacement method of an inter-electrode insulating sleeve of a generator collector ring. The replacement method comprises the following steps that 1), a part of a tensioningbolt and corresponding tensioning nuts are removed between an upper collector ring and a lower collector ring, and then a part of insulating sleeve located on the upper surface of the upper collectorring and on the lower surface of the lower collector ring is removed; and step 2), an operation screw rod and an operation nut are installed on the upper collector ring and the lower collector ring,and then the residual tensioning bolt and the residual tensioning nuts between the upper collector ring and the lower collector ring are removed, and the residual insulating sleeve which is located onthe upper surface of the upper collector ring and on the lower surface of the lower collector ring is replaced. By adoption of the replacement method, normal operation and maintenance work of the collector ring are facilitated.

Description

technical field [0001] The invention relates to the technical field of a magnetic flap liquid level gauge, in particular to a method for replacing an insulating bushing between poles of a collector ring of a generator. Background technique [0002] The collector ring is an important electrical component of the hydro-generator, and the insulation of the upper and lower collector rings to the ground directly affects the normal operation of the unit. Due to the influence of carbon dust, oil pollution, etc., especially the long-term operation, as the insulating parts age and become brittle, if the collector ring insulation is found to be unqualified during operation or maintenance, it is necessary to replace the insulating sleeve. Due to the influence of working space, maintenance period, etc., and the weight of a single collector ring is 225Kg, and the distance between poles is only 67mm, it is difficult to replace the insulating bushing. There are three general cases: [000...
