Novel lightning protection cabinet

Abstract

The invention belongs to the field of lightning surge and overvoltage protection of instrument systems on petrochemical fields and mainly relates to a novel lightning protection cabinet. The novel lightning protection cabinet mainly comprises a backboard, wiring modules, lightning protection modules, signal analysis modules and a supporting frame, wherein the backboard, the wiring modules, the signal analysis modules and the supporting frame are all installed in the lightning protection cabinet. Signal lines enter the lightning protection cabinet and then are connected to the wiring modules through wiring terminals, the lightning protection modules are inserted in the wiring modules in a pluggable mode and are used for protecting the signal lines against lightning surge, the wiring modules are installed on the front side of the backboard, and each signal analyzing module corresponds to one wiring module and is installed on the back side of the corresponding wiring module. According to the novel lightning protection cabinet, instrument signals and the lightning function are managed in a unified mode, wiring is clear, the hot plugging technology is adopted for the lightning protection module, installation and maintenance are easier and more convenient, and reliability is greatly improved.

Description

technical field [0001] The invention belongs to the field of lightning and overvoltage protection, and is mainly applied to the lightning and overvoltage protection of petrochemical field instrument systems and other signal centralized monitoring areas. Background technique [0002] Lightning is a special weather phenomenon caused by the discharge of charged clouds in the air. Lightning threatens the safe and stable operation of equipment in various fields such as construction, railways, civil aviation, communications, industrial control, and military. Installing protective devices on metal lines such as power lines, signal lines, and control lines connected to equipment is one of the important measures for lightning protection. As the petrochemical industry is an important lifeline of the whole country and region, it is very important and necessary to protect it from lightning. In recent years, the automation level of the petrochemical industry has been continuously improv...

Problems solved by technology

Due to the large number and types of field instruments, a large number of instrument signal cables enter the control room from the field, resulting in a large number of surge protectors in the control room that need to be wired and installed

As mentioned above, most of the surge protectors are independently installed on the guide rail, without warning function, and have the following disadvantages: the installation of surge protectors is scattered; the wiring is confusing; it takes up a large space and is inconvenient to install; Centralized monitoring and management of lightning conditions; when the surge protector is damaged and needs to be repaired or replaced, the operation is inconvenient, which further affects the performance and protection effect of the surge protector, and also affects the normal operation of the petrochemical system, reducing Its work efficiency and safety stability

However, this utility model still has deficiencies: it fails to consider the actual application situation of the petrochemical field, it is inconvenient to install and connect, and it is inconvenient to operate and maintain
