Description

A positioning and moving GIS isolating switch motor replacement locking jig

Technical field:

The utility model relates to a GFM (ZF33)-126 type GIS isolating switch electric 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.

Background technique:

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.

In the process of overhauling the motor of the GFM (ZF33)-126 GIS isolating switch mechanism, because the motor is fixed on the motor body panel with hexagon socket screws, the distance between the motor panel and the rotating gear is narrow, and ordinary screwdrivers cannot be disassembled. In addition, the screw is long, even if it can be loosened with a special screwdriver for processing, it still cannot be taken out. Once the motor in the GFM (ZF33)-126 type GIS isolating switch mechanism is damaged and needs to be replaced, there are two replacement options: 1. Remove the secondary wiring, remove the front panel of the mechanism, and replace the motor after releasing the transmission interlocking parts. 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 110kV combined electrical disconnector mechanism in the "Working Hour Quota Standard for the Core Business Team of the Substation Overhaul and Maintenance Professional Team". Moreover, the outdoor installation height of the GFM (ZF33)-126 GIS isolating switch is 2.0 meters, and the staff will overhaul it for a long time, which will pose a safety risk and cannot guarantee the personal safety of the personnel.

Utility model content:

The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art and provide a simple structure, convenient and reliable installation, which can complete the maintenance work with high quality and high efficiency within the specified time, improve the quality of equipment maintenance, shorten the maintenance time, and improve work efficiency. At the same time, it can reduce the labor intensity of the staff, ensure the safety of on-site maintenance operations, and ensure the reliability of power supply. The GIS isolating switch motor that can be positioned and moved can replace the locking fixture.

The purpose of this utility model can be achieved through the following measures: a GIS isolating switch motor that can be positioned and moved is replaced with a locking fixture, which includes a support screw, which is characterized in that one end of the support screw is connected to the support screw positioning screw, and the other end of the support screw One end is connected to the lock nut positioning screw, and the lock nut positioning screw is connected to the rotating handwheel. The positioning fixture is stuck on the support screw and the lock nut positioning screw through the first installation slot and the second installation slot. The lock nut On the positioning screw, the two sides of the positioning fixture are respectively provided with a first positioning fixture fixing nut and a second positioning fixture fixing nut.

Compared with the prior art, the utility model can produce the following positive effects:

1. The utility model rotates the handwheel to turn the locking nut to locate the screw, which can achieve the purpose of fixing in the original screw hole, and does not need to open another hole.

2. The utility model uses the supporting screw instead of the fixing screw on the front panel of the mechanism, which can realize the free movement of the front panel of the mechanism on the supporting screw without falling off, avoid manual hand support, reduce the labor intensity of the staff, and ensure the safety of the operation.

3. Adjust the position of the fixed positioning fixture by moving the position of the positioning fixture and the fixture fixing nut on the locking support screw, so as to realize the support and fixation of the front panel of the mechanism at different positions.

The utility model has the advantages of simple structure, convenient and reliable installation, high-quality and high-efficiency maintenance work can be completed within a specified time, the quality of equipment maintenance is improved, maintenance time is shortened, and work efficiency is improved. At the same time, it can reduce the labor intensity of the staff, ensure the safety of on-site maintenance operations, and ensure the reliability of power supply.

Description of drawings:

Fig. 1 is the structural representation of the utility model.

The specific embodiment: below in conjunction with accompanying drawing, the best embodiment of the present utility model is described in detail:

Embodiment: A positionable and movable GIS isolating switch motor replacement locking jig (see Figure 1), which includes a support screw 5, one end of the support screw 5 is connected to the support screw positioning screw 6, and the other end of the support screw 5 is connected to the lock The tightening nut positioning screw 4, the locking nut positioning screw 4 is connected to the rotating handwheel 1, and the positioning fixture 7 is stuck on the support screw 5 and the locking nut positioning screw 4 through the first installation slot 8 and the second installation slot 9 Above, the two sides of the positioning jig 7 on the locking nut positioning screw 4 are respectively provided with a first positioning jig fixing nut 2 and a second positioning jig fixing nut 3 .

When in use, the support screw 5 is fixed in the original fixing screw hole of the secondary wiring arrangement on the front panel of the disconnector mechanism by rotating the handwheel 1 and the support screw positioning screw 6, and the positioning fixture 7 is passed through the first installation slot 8, the second The installation card slot 9 is installed on the support screw rod 5 and the locking nut positioning screw 4, and the position of the positioning fixture 7 is adjusted by the second positioning fixture fixing nut 3 along the locking nut positioning screw 4 to adjust the front panel of the isolating switch mechanism and the rotation. The position of the gear spacing increases the construction space. After the adjustment is in place, use the second positioning fixture fixing nut 3 and the first positioning fixture fixing nut 2 to lock and fix the positioning fixture 7 to ensure that the front panel of the isolating switch mechanism does not shift or fall off, that is, Motor replacement work is possible.
