Embodiment 1
[0035] like Figure 2~3 As shown, a method for overhauling and replacing a hydraulic disc spring operating mechanism of a 500kV circuit breaker includes the following steps:
[0036] S1: Hydraulic Cart 7 ( figure 2 Only the plate body part of the hydraulic trolley is shown) after placing the support block 8, the support plate 9 and the maintenance and replacement platform 10 in sequence, they are pushed to the bottom of the hydraulic disc spring operating mechanism 11 to be repaired and replaced;
[0037] S2: Press the handle of the hydraulic cart 7 several times to raise the height of the hydraulic cart 7 until the disc spring portion of the hydraulic disc spring operating mechanism 11 is in contact with the support module on the upper part of the maintenance and replacement platform 10;
[0038] S3: Start the maintenance and replace the telescopic module on the upper part of the platform 10 to stably support the energy storage part of the hydraulic disc spring operating me...
