Abstract

The invention relates to a protective sealing element of a high-voltage electrical element of an electric power system, in particular to an insulating protective silicon rubber case of a voltage transformer. Comprising a positioning sleeve umbrella, a leading-out wire sleeve I, a main body column sleeve and a leading-out wire sleeve II, one end of the main body column sleeve is of a closed structure, and the other end of the main body column sleeve is of an open structure; the positioning sleeve umbrella is arranged at the opening end of the main body column sleeve; and the lead-out wire sleeve I and the lead-out wire sleeve II are arranged on the side wall of the main body column sleeve. The invention is optimally designed by combining the structural characteristics of the outdoor voltage transformer, the size of the inner cavity is tightly matched with the wiring part of the transformer, and nested installation is carried out according to the tensile property of silicone rubber, so that convenience and rapidness are realized.

Description

technical field [0001] The invention relates to a protective seal for high-voltage electrical components in a power system, in particular to an insulating and protective silicone sleeve for a voltage transformer. Background technique [0002] The existing outdoor voltage transformer is used in power systems and electrical equipment. The primary terminal of the product is directly electrically connected to the high-voltage busbar in actual operation. Usually, the lead cable is attached to the auxiliary terminal lug bolts for fastening. The metal conductor at the connection is directly exposed to the atmosphere. The primary terminal is corroded by the atmospheric environment, rain, snow, wind and sand for a long time, and the terminal is prone to corrosion. In severe cases, it will lead to poor electrical contact or open circuit, which will affect the safe operation of power supply. In addition, during the operation process, due to the harsh conditions such as smog and conden...
