High-voltage electric cabinet with remote monitoring

Abstract

The invention discloses a high-voltage electric cabinet capable of being remotely monitored. The high-voltage electric cabinet comprises a box body, wherein a fireproof layer coats the surface of the box body; a halogen-free coating is arranged on the fireproof layer; a plurality of power distribution racks for placing power distribution equipment are transversely arranged in the box body; a first isolation plate is arranged above the power distribution racks, and is provided with a communication system which is used for communicating with the outside; the communication system comprises a communicator device and a communication antenna; the communicator device communicates with the outside by the communication antenna; the communication antenna is arranged on an antenna plate; the antenna plate is arranged above the first isolation plate; and a second isolation plate is arranged above the antenna plate. The antenna is combined with the isolation plates, so that the relatively high requirements for electrical properties including the omnidirectivity and gain of the antenna and the front-to-back ratio are achieved; and auxiliary equipment is preferably provided to improve the anti-jamming capability of the antenna.

[0002] In the Internet age, people prefer to add communication systems to various equipment to facilitate real-time remote observation of equipment status and information to prevent equipment damage; communication is inseparable from communication antennas that enable signal transmission and reception; so far in high-voltage distribution There are few cases where communication equipment is installed on the electric cabinet or distribution box, because there is an unavoidable factor, that is, the electric field of the power distribution cabinet will affect the transmission parameters, gain and omnidirectionality of the antenna; The antenna itself needs to have better performance in the direction of the environment; the current mainstream equipment communication antenna works better in the 700-1000MHz frequency band, so in this frequency band, design a suitable for high-voltage power distribution equipment such as power distribution cabinets. The system antenna is very urgent, and the electrical performance of the antenna is required, that is, the emission performance, such as its omnidirectionality, gain, and front-to-back ratio require better electrical performance, and it is best to have auxiliary equipment to improve the anti-interference ability of the antenna
