Description
Technical Field
The invention relates to the technical field of electric power tools, in particular to a combined cable end protective cover.
Background
With the continuous and rapid development of national economy, the electricity consumption of people's life and production is continuously improved, and the stability and reliability of power supply become important to the work of power companies. However, the power system still has many hidden trouble points which affect the safety of people and even endanger the personal safety! Wherein,
in the construction and maintenance of an electric power system, the treatment of the end of a wire of a low-voltage insulated line is a hidden danger point which is easy to neglect, the end of the wire is not well treated, and the potential safety hazards of electric shock and short circuit of foreign objects are easy to cause. At present, in construction and maintenance, the insulation treatment of a low-voltage overhead insulated line terminal is mainly divided into two types: one is to wind with an insulating tape, and the other is to use a heat-shrinkable cable cap.
The thermoplastic cable end cap has better insulating property. However, when the cable end socket is used, the heat-shrinkable end socket cap needs to be heated for a period of time by using liquefied gas, so that the heat-shrinkable end socket cap can be heated, shrunk and wrapped on the end of the wire. The process needs to carry a heavy liquefied gas tank, and the liquefied gas tank is heavy, inconvenient to carry, not easy to store and easy to explode, so that the liquefied gas tank is rarely used in practical construction. According to survey statistics, the end of the conductor in the low-voltage distribution room of the whole Guangdong power grid uses less than 3% of a heat-shrinkable cable sealing cap, and more than 95% of the end of the overhead conductor is wound by using an insulating adhesive tape to realize insulation and water resistance.
The method for realizing insulation by using the insulating tape winding mode is simple to operate and saves cost. But the insulating adhesive tape can be aged and fall off after the wire is installed for 1-2 years, so that the terminal of the insulating wire is exposed, and the wire core is oxidized. Meanwhile, the exposed lead terminal is easy to contact with peripheral greening or buildings, so that potential safety hazards are formed; and the fault of interphase short circuit is easy to occur between adjacent terminal heads.
