Description

Insulation isolation fixtures for 10kV overhead power distribution equipment

technical field

The utility model relates to the field of power grid distribution. the

Background technique

For the high-voltage insulated wires of 10kV distribution lines are damaged by external force or the high-voltage vertical bottle is deteriorated, the high-voltage insulated wires fall off from the vertical bottle and fall on the iron cross-arm. The insulation of high-voltage wires deteriorates, causing the distribution line to be grounded. If this abnormality occurs in both two-phase or three-phase wires, it will cause an accident of line tripping. Therefore, when the high-voltage vertical bottle is broken or does not work, it is very necessary to fix the insulated wire and place it in contact with the iron cross-arm. the

Utility model content

The utility model is to meet the demand for temporarily fixing the insulated wire when the vertical bottle is broken or not working, and also to meet the insulation between the insulated wire with deteriorated insulation and the iron cross-arm so as to avoid large-scale power outages. It is proposed for 10kV overhead Insulation isolation fixtures for power distribution equipment. the

The top of the floor pillar is fixed on the lower surface of the floor, and the bottom end of the floor pillar is fixed on the upper surface of the fixing clip. the

The cover plate, the left side plate, the right side plate and the bottom plate are all insulating plates. the

The fixing clip is fixed on the iron cross arm of the 10kV overhead power distribution equipment by screws. the

The other end of the cover plate is fixed to the top of the left side plate or the right side plate through a lock. the

Beneficial effects: the device described in the utility model can play the role of temporary insulation transition on the 10kV high-voltage insulated line, and the insulating groove of the device is used to temporarily fix the insulated wire, thereby satisfying the temporary fixing when the vertical bottle is broken or not working The demand for insulated wires. At the same time, when the insulation of the insulated wires is degraded due to long-term wind and sun, once the insulated wires with degraded insulation come into contact with the iron cross-arm, it is very dangerous, which will easily cause large-scale power outages and ensure unreliable power supply. Place the insulated wire with deteriorated insulation in the insulation groove of the device, thereby ensuring the isolation of the insulated wire with deteriorated insulation and the iron cross-arm, and meeting the insulation between the insulated wire with deteriorated insulation and the iron cross-arm to avoid large-scale power outages requirements, and the device has a simple structure and is easy to operate. The utility model is also applicable to other power distribution occasions. the

Detailed ways

Specific Embodiments 1. Referring to Figure 1, Figure 2 and Figure 3, this embodiment will be described in detail. In the figure, the cross arm is 1, and the insulated wire is 2. The insulation isolation and fixing device for 10kV overhead power distribution equipment described in this embodiment , which includes: cover plate 3, left side plate 4, right side plate 5, bottom plate 6, bottom plate pillar 7 and fixing clip 8;

The left side plate 4 and the right side plate 5 are respectively fixed on the left and right sides of the base plate 6, and the left side plate 4 and the right side plate 5 are parallel, the bottom surface of the left side plate 4, the bottom surface of the bottom plate 6 and the right side plate The bottom surface of 5 is located on the same horizontal plane, and the distance between the left side plate 4 and the right side plate 5 is 1.2 times of the diameter of the wire 2; one end of the cover plate 3 is flexibly connected with the left side plate 4 or the right side plate 5 , and the other end of the cover plate 3 is 3cm to 5cm away from the right side plate 5 or the left side plate;

The top of the floor pillar 7 is fixed on the lower surface of the floor 6 , and the bottom of the floor pillar 7 is fixed on the upper surface of the fixing clip 8 . the
