Detailed Description
First embodiment, as shown in fig. 1, fig. 2, and fig. 3, the transformer substation secondary safety measure execution isolation sleeve disclosed in this embodiment includes a dust-proof core sealing cap 1, a positioning ring 2, a slipknot tie hole 3, and a slipknot tie 4.
The dust-proof seal core cap 1 is a hollow round cap with an opening at the tail end and is integrally formed by adopting an insulating wear-resistant PVC material.
The inner cavity of the dustproof sealing core cap is padded with a layer of insulating film 11 to enhance the insulating property.
The positioning ring 2 is in a circular ring shape, and the head end of the positioning ring is connected with the tail end of the dustproof seal core cap; the tail end of the dustproof seal core cap is larger than the head end of the positioning ring, and the tail end caliber of the positioning ring is larger than the head end caliber of the positioning ring. The positioning ring is an elastic soft film with large friction force, and can be attached to a secondary thread end to primarily position the secondary thread end when in use.
The slipknot hole 3 is fixed at the side end of the positioning ring and is a C-shaped handle; the slipknot ribbon 4 passes through the slipknot ribbon hole to encircle on the lateral wall of holding ring, can fasten the holding ring through the ribbon and be fixed in secondary thread, reliably overlaps the dustproof core sealing cap and arranges in secondary thread.
The movable buckle binding belt can be limited up and down by arranging the movable buckle binding belt hole.
When the isolation sleeve needs to be used, the positioning ring is outwards expanded, the dust-proof core sealing cap is sleeved on the secondary thread end, and then the positioning ring is loosened and attached to the secondary thread end; and then the slipknot tying band passes through the slipknot tying band hole to be surrounded on the positioning ring and then is fastened and fixed, so that the reliable isolation of the secondary thread end is realized.
