[0002] With the development of social economy, the demand for electricity is increasing. In order to ensure the social demand, the installation and maintenance work of substation equipment is also increasing. When replacing or overhauling heavy column-mounted equipment such as isolating switches and transformers, etc., Cranes are mainly used for lifting, long preparation time, slow work efficiency, long power outage time, high cost, etc. Second, the use of cranes in substation intervals may cause power outages at adjacent intervals or busbars due to insufficient safety distance. Those equipments to be repaired A lot of manpower has to be carried on the shoulders during the operation, which increases the labor intensity of the operators, prolongs the power outage time, and brings more inconvenience to the production or life of the people.

Embodiment 1
[0035] A method for replacing a single-column vertically telescopic outdoor high-voltage AC isolating switch, the steps of which are as follows:
[0036] (1) Fix the portable special spreader on the equipment frame,
[0037] (2) Fix and bind the upper and lower conductive arms of the three-phase knife switch with hoops or ropes to prevent closing.
[0038] (3) Remove the three-phase linkage horizontal connecting rod of the knife switch,
[0039] (4) Use the lifting rope to lift the main output rotary porcelain bottle of phase B for 10 cm, and replace the ground knife locking plate on the main output shaft of phase B.
[0040] (5) Replace the three-phase knife switch limit flange and drive rod,
[0041] (6) Replace the knife switch three-phase linkage horizontal link arm,
[0042] (7) Install the knife switch three-phase linkage horizontal connecting rod,
[0043] (8) Carry out the three-phase linkage debugging of the knife switch.
[0044] as described Figure 1-7 The po...

The invention discloses a single-pole perpendicularly-telescopic outdoor high-voltage alternating-current disconnector replacing method. According to the method, a disconnector is replaced by the utilization of a portable lifting appliance, thus, power outage time can be greatly shortened, labor intensity is reduced, safety hazards in the hoisting process are reduced, the equipment power outage range is reduced, equipment out-of-service time is shortened, and working efficiency is greatly promoted.
