Description
Technical Field
The invention relates to auxiliary facilities of an electric power system, in particular to a novel bus bridge conductor insulating sheath.
Background
The bus bridge, also known as a bridge connection, is a main connection that connects two power supply inlet lines to two transformers using a jumper breaker BCD. The transformer low bushings are routed to a bridge link between the high voltage switchgear, commonly referred to as a low bus bridge. The insulation of present generating line bridge conductor adopts heat shrinkage bush mostly, and the heat shrinkage bush material and the theory of use that the conductor of generating line bridge used: the heat-shrinkable sleeve is a heat-shrinkable packaging material, can be shrunk when being heated, and can be divided into a PVC heat-shrinkable sleeve, a PET heat-shrinkable sleeve, an irradiation cross-linked PE heat-shrinkable sleeve, a 10KV high-voltage conductor protection heat-shrinkable sleeve and a 35KV high-voltage conductor protection heat-shrinkable sleeve according to the materials. A heat-shrinkable tube used for conductor is prepared from thermoplastic polyolefin as basic material, flame retardant and assistant through extruding out to become tube, gamma-ray radiating or high-energy electron beam bombarding to generate cross-linking on the segment of linear molecule, heating, expanding its diameter by several times, cooling, and heating to 80-120 deg.C until the diameter of heat-shrinkable tube is reduced to the size before expansion. The mode of applying the heat shrinkable tube to the 10kV bus bridge is as follows: the conductor of the current bus bridge is wrapped by a single piece of a heat shrinkable sleeve, and the heat shrinkable sleeve is tightly sleeved on the bus conductor by utilizing hot air. And then the conductors are stacked according to requirements and are installed by using the insulator and the bus clamp.
However, the application of heat shrinkable sleeves as the insulating material of the 10kV bus bridge conductor has the following disadvantages: (1) during thermal shrinkage, a propane lamp, liquefied gas open fire, a gasoline blowtorch and an industrial electric hot air gun are mostly used for heating single surfaces, so that the thermal shrinkage is unbalanced easily, the thickness is uneven, and the thermal shrinkage tube is easy to tear due to the principle of cold shrinkage and thermal expansion in practical application. (2) Aging of the thermal shrinkable sleeve: the thermal shrinkable sleeve is made of plastic materials, is attached to the surface of the bus, generates heat under the condition of current, naturally ages for a long time (generally about 2 years), and falls off after ageing, so that the thermal shrinkable sleeve cannot play an insulating role, and the insulating effect is reduced.
