A positioning and moving gis isolating switch motor replacement locking jig

Abstract

The invention discloses a locatable and movable latching fixture for replacing a GIS (Geographic Information System) isolating switch motor. The latching fixture comprises a supporting screw (5), and is characterized in that one end of the supporting screw (5) is connected with a supporting screw locating screw thread (6), the other end of the supporting screw (5) is connected with a locking nut locating screw thread (4), the locking nut locating screw thread (4) is connected with a rotating hand wheel (1), a locating clamp (7) is clamped on the supporting screw (5) and the locking nut locating screw thread (4) through a mounting clamping groove, and a first locating clamp fixing nut (2) and a second locating clamp fixing nut (3) are respectively arranged on the locking nut locating screw thread (4) and on the two sides of the locating clamp (7). The latching fixture is simple in structure and convenient and reliable in installation, can complete the overhauling operation with high quality and high efficiency within specified time, improve the equipment overhauling quality, shorten the overhauling time and improve the working efficiency, and meanwhile, can relieve the labor intensity of workers, ensure the operation safety of in-situ overhauling and ensure the power supply reliability.

Description

[0001] Technical field: [0002] The invention relates to a GFM (ZF33)-126 type GIS isolating switch motor mechanism motor replacement tool, in particular to a positionable and movable GIS isolating switch motor replacement locking jig, which belongs to the technical field of power system substation maintenance. [0003] Background technique: [0004] At present, the 110kV voltage level substation equipment in the substation generally adopts the GIS type, which combines the isolating switch with the circuit breaker, voltage transformer, current transformer, lightning arrester, and grounding switch. It has the advantages of small footprint, large short-circuit current, and arc extinction. The advantages of strong ability and relatively small maintenance workload. GFM(ZF33)-126 type GIS device is equipped with optional isolating switches all adopt electric mechanism, which is fast and flexible in operation. [0005] In the process of overhauling the motor of the GFM (ZF33)-126 G...

2. Do not remove the secondary wiring, but only remove the fixing nuts on the front panel of the mechanism. Another maintenance personnel is required to pull out and hold the front panel of the mechanism, and then replace the motor after increasing the distance between the motor panel and the rotating gear. The above two replacement schemes take a long time and have low work efficiency, which cannot meet the requirement of 24 working hours for the inspection and elimination of the isolating switch mechanism of 110kV combined electrical appliances in the "Working Hour Quota Standard for the Core Business Team of Power Transformation Maintenance Professional Team"

And the outdoor installation height of the GFM(ZF33)-126 GIS isolating switch is 2.0 meters. The staff will overhaul for a long time, which will pose a safety risk and cannot guarantee the personal safety of the personnel.
