Abstract

The invention relates to the field of electronic communication equipment, in particular to a sealed shielded power network protection cabinet. The cabinet comprises a cabinet body, a cabinet door, a voltage stabilizer, a circuit breaker, a contactor, a transformer, a relay, a current Hall transformer, a switch power supply, a digital board, an analog board and a connecting terminal. A transition chamber is arranged outside the cabinet door; and a foaming plastic layer, a metal shielding layer and an elastic foam layer are arranged in the plates of the cabinet body, the cabinet door and the transition chamber respectively. The transition chamber and the cabinet body are connected integrally to encircle the cabinet door, and a sealed door is arranged on the transition chamber. The metal shielding layers added in the plates of the cabinet body and the cabinet door can effectively prevent electromagnetic radiation and electromagnetic leakage, obviously improve the positioning reliability, improve the production efficiency and ensure system safety and power supply quality safety; and the transition chamber can greatly improve the protective tightness.

Description

technical field [0001] The invention relates to the field of electronic communication equipment, in particular to a sealed shielding power network protection cabinet. Background technique [0002] At present, the existing power protection cabinets are basically a regular structural frame of metal or other materials in terms of overall structure, generally a frame structure, with only aesthetic and application requirements, and basically only the rigidity of the material is required in the selection of materials And corrosion resistance, not suitable for the protection of electromagnetic radiation, resulting in electromagnetic radiation and electromagnetic leakage, with the development of science and technology and the enhancement of human awareness of the protection of the living environment, there have been a variety of equipment for the treatment of electromagnetic radiation , such as a shielding cabinet, the shielding cabinet is mainly divided into a cabinet body and a ca...
