Problems solved by technology
However, the use of insulating tape has the following disadvantages: 1. The insulating tape is easy to fall off or cause the metal end of the wire to be exposed, which poses a greater safety hazard; The insulating tape is heated or bandaged for a long time, and the adhesive layer is easy to separate and adhere to the metal end of the wire, thus affecting the cleanliness of the secondary wiring

The invention provides a special isolation sleeve for secondary wiring of electric power, which mainly includes an isolation sleeve main body, a positioning sleeve, a coil spring, a first protective sleeve and a second protrusion; wherein, the isolation sleeve main body is one side made of insulating material Closed tube body structure, and a groove for storing paper strips is provided at the end close to the closed side; the main body of the spacer sleeve is provided with a positioning sleeve, a coil spring, a first protective sleeve and a The second protrusion; the coil spring and the first protective sleeve are both sleeved on the main body of the spacer sleeve, and the first protective sleeve is made of transparent material; under the action of the coil spring and the second protrusion, the first protective sleeve will groove Completely shielding, pushing the first protective cover can fully expose the groove. It can replace the insulating tape to insulate and protect the metal end of the wire, and solve the problems that the insulating tape is easy to fall off or the metal end of the wire is exposed, and it is difficult to mark the wiring clearly, and it is easy to affect the cleanliness of the secondary terminal.
Description
technical field [0001] The invention relates to the technical field of insulation protection, in particular to a special insulating sleeve for secondary wiring of electric power. Background technique [0002] With the development of power system automation technology, the power secondary system has been inseparable from the power primary equipment, and the secondary system is widely used in power transformation and distribution equipment. There are a large number of on-site secondary system wirings such as power system substations and power distribution rooms. When isolating useless secondary wiring during on-site work, or temporarily disabling some secondary wiring, it is usually detached with insulating tape. The secondary wiring has to be insulated. However, the use of insulating tape has the following disadvantages: 1. The insulating tape is easy to fall off or cause the metal end of the wire to be exposed, which poses a greater safety hazard; When the insulating tape ...
