Metal net electromagnetic shielding device for outdoor minitype wireless transmitting/receiving device of high voltage transforming plant

Abstract

A metallic network electromagnetic screen used for a miniaturized wireless transmitter-receiver outside a high pressure substation is composed of a shell and a top cover; the shell consists of an external insulating shell, an internal insulating shell and a metallic network interlayer between the shells; the top cover consists of an external insulating top cover, an internal insulating top cover and a metallic network interlayer between the top covers. The wall edge of the internal insulating shell is higher than the external insulating shell; the side wall edges after the assembly of the two layer top covers form a groove and match with the height difference of the two parts of the shell and the thickness of the internal insulating shell; the shell and the top cover is connected in an articulating way. The invention uses insulating material as the main shell so as to effectively prevent from the damage of the safe phase spacing of the substation equipment, avoid the discharge phenomena produced by passing high current, while the internal metallic network can carry out the electromagnetic shielding protection on the whole device and helps the equipment work normally under the electromagnetic environment of the substation. Compared with the ordinary method of adding in a metallic interlayer and the method of spraying the inner wall with conducting paint, the method is of lower cost and more convenient application.

Description

【Technical field】: [0001] The invention belongs to the technical field of electric power supply auxiliary facilities, in particular to electromagnetic compatibility, and specifically relates to an electromagnetic shielding device for a small outdoor wireless transceiver device of a high-voltage substation. 【Background technique】: [0002] With the rapid growth of my country's economy, the power supply is increasing day by day, and the continuous and rapid growth of power supply has brought a series of safety problems to the high-voltage power grid equipment. In order to prevent various power accidents, the workload of safe operation monitoring is rapidly increasing. , and with the continuous improvement of the comprehensive automation level of substations, the real-time sending and receiving of various data is becoming more and more important. Since wireless communication does not need to consider the problem of wiring, it is beneficial to reduce the space occupation of the s...
