Description
Technical Field
The invention relates to the field of power grid overhaul, in particular to a special tool for disconnecting switch overhaul and an overhaul method for replacing a hoop without power failure.
Background
The actuating mechanism output shaft and the vertical transmission connecting rod of the outdoor high-voltage isolating switch commonly used in the transformer substation at present are connected through the anchor ear, and the torque output by the mechanism acts on the anchor ear for a long time, because the traditional anchor ear only tightly holds the connecting rod through the locking pressure of a bolt, under the effect of the long-time repeated positive and negative rotation high torque, the phenomenon of sliding off easily occurs, and then the hidden danger that the disconnecting link is not opened and closed in place is caused. Solves this kind of hidden danger can be through punching on the staple bolt, increase a through bolt, lock the staple bolt and be connected with the connecting rod, but through experimental investigation discovers that the used staple bolt of former producer is cast aluminum alloy part mostly, and is relatively poor because of the great toughness of cast aluminium silicon content, and it is bigger through long-time weathering hard brittleness, and direct punching causes the staple bolt fracture easily, has bigger potential safety hazard to the operation safety, and direct punching is unfavorable. The novel anchor ear is manufactured by adopting 6061 type extrusion type aluminum alloy, the toughness strength of the aluminum alloy is higher, the oxidation resistance and the corrosion resistance are very strong, and the aluminum alloy is the most commonly used high-quality aluminum alloy for power accessories; in the novel anchor ear precast bolt hole, a stainless steel positioning bolt pin with a locking nut is arranged.
The novel hoop which is prefabricated in the south network anti-accident measure is required to be replaced and is required to be combined with power failure maintenance to finish transformation, but the stock of the isolating switch in operation is huge, the operation of the power grid is realistic, the hoop cannot be replaced in a short time in sequence in a power failure mode, some of the hoop cannot be replaced in a power failure mode, and the task of completely completing the anti-accident measure is remote and indefinite.

Preferably, the clamp is made of an aluminum alloy material.
Preferably, the clamp clamps the GW4 disconnecting link and the disconnecting link which is communicated with the GW4 disconnecting link structure.
An overhauling method for replacing a hoop of an isolating switch without power outage, which is applied to the special tooling for overhauling the isolating switch, comprises the following steps of:
s1: the upper end of the special tool is tightly held at a proper position of a vertical connecting rod at the upper part of the anchor ear, and the lower end of the special tool is fixed on a flange of the mechanism output, so that the mechanism output flange is fixedly connected with the vertical connecting rod through the special tool;
s2: marking the original positions of the vertical connecting rod and the mechanism flange of the fixed tool by using a marker pen, removing the original anchor ear, installing a new anchor ear with a locating pin back to the mechanism, and locking the new anchor ear according to the required moment;
s3: after the new anchor ear is locked, the special tool is dismantled, the mark is observed, and no displacement between the mechanism flange and the vertical connecting rod is ensured again, so that the isolating switch can normally operate.
Compared with the prior art, the technical scheme of the invention has the beneficial effects that:
according to the invention, through the bolts at the upper end of the tool transition plate, when the isolating switch is not closed in place or the disconnecting switch is not closed in place, the position of the contact of the electrified micro-switching switch is realized through the assistance of the adjusting nut, so that the switch is closed in place, the problems that the stock of the isolating switch in operation is huge, the hoop cannot be replaced in a short time in turn in a power outage way, some of the hoop cannot be replaced in a power outage way, the remote and indefinite problems of anti-accident measure tasks are completely completed, the power outage cost is saved, and huge economic benefits are generated are solved.
