Abstract
The invention belongs to the field of thunder surge and overvoltage protection of petrochemical on-site instrument systems and mainly relates to a novel lightning protection cabinet. The novel lightning protection cabinet is composed of an I-shaped frame, a back board, a module slot, a lightning protection module, a data acquisition processing box, a liquid crystal display screen, and a function button, wherein the I-shaped frame, the back board, the module slot, the lightning protection module, and the data acquisition processing box are all arranged inside the cabinet; the liquid crystal display screen and the function button are located on the front face of the cabinet; the module slot is located on the back board and fixed on a column of the I-shaped frame; the lightning protection module is plugged in the module slot and a terminal slot transmits signals to the data acquisition processing box. The intelligent detection, power supply, and liquid crystal display screen query are realized, and the thunder surge and overvoltage discharge are conducted through a ground terminal. At the same time, the terminal slot connects a line on a wiring terminal to the lightning protection module. Thus, the instrument signal lightning protection is monitored and managed in a unified manner, which is equivalent to the effect that thousands of lightning protection points are integrated into one point. The novel lightning protection cabinet is clear in wiring, lowered in cost, and easy and convenient to mount and maintain.
Description
Technical field
The invention belongs to thunder and lightning and overvoltage protection field, be mainly used in thunder and lightning and the overvoltage protection of guarded region in petrochemical industry field instrument system and other set of signals.
Background technology
Petrochemical industry is the important lifeline of whole countries and regions, petrochemical industry automatization level improves constantly in recent years, Computerized monitor system, computer management system, data transmission applications are more and more general, a large amount of precision instrumentation is often installed at petrochemical industry scene, signal kinds is varied, site environment is intricate, and this kind of instrument system and circuit antijamming capability weakness, lightning overvoltage and overcurrent will cause great harm to it.Between petrochemical industry process units and control room, the cable of substantial amounts is main path lightning surge being introduced Instrumentation and Control system; carry out lightning protection and need consider instrument system ground connection, instrumentation shielding, signal line shielding, reasonable line arrangement, equipotential link, installation Surge Protector; with regard to Surge Protector; there is in side, control room thousands of cables to need to install, how to unify, orderly management is the key ensureing that system safety is normally run.
In petrochemical industry, the ground of the core of monitoring management that to be petrochemical industry to all instrument, equipment carry out in control room, be the comprehensive building with the function such as process control, instrument maintenance, each road field instrument signal all needs the control rack being aggregated into control room to carry out unified management.Signal cable between field production device and control room is main path lightning surge being introduced Instrumentation and Control system; in instrument side and control room, a kind of method that Surge Protector (SPD) is effective suppression surge is installed, instrument infringement and associated loss can be greatly reduced.Due to field instrument model, One's name is legion, a large amount of instrument signal cable enters control room from scene, causes control room to have a large amount of Surge Protector (SPD) to need wiring and installation.Mostly independently to be installed on guide rail, to there is no alarm indication function, cause following deficiency: SPD mounting points is disperseed; Wiring is unintelligible; Take other cabinet space; Cannot in real time to lightning protection situation Centralizing inspection and the management of instrument.How effective lightning protection situation to several thousand holding wires in control room carries out unified management and maintenance, is the key ensureing that system safety is normally run.
Summary of the invention
In order to effectively solve the above prior-art problems, the present invention proposes a kind of Novel lightning-proof cabinet.Lightning protection cabinet be positioned at monitoring cabinet side, field control room, for the corresponding lightning-protection module of each line configuring, ensure the equipment of circuit away from thunder disaster.
Technical scheme of the present invention is, a kind of Novel lightning-proof cabinet, comprises I-shaped frame, backboard, module slot, lightning-protection module, data acquisition process box, LCDs, function button.Wherein said I-shaped frame, backboard, module slot, lightning-protection module, data acquisition process box are all loaded on interior of equipment cabinet.Described LCDs, function button are positioned at cabinet front.Described module slot is positioned on backboard, is fixed on the column of I-shaped frame.Described lightning-protection module is plugged in module slot according to signal line type, transmits signals to data acquisition process box respectively by the terminal groove in module slot, realizes Intelligent Measurement, power supply and LCDs inquiry; Carry out thunder and lightning by earth terminal and superpotentially to release; Terminal groove is by the circuit access lightning-protection module on binding post simultaneously.
A kind of Novel lightning-proof cabinet of the present invention Appropriate application enclosure interior, module slot is designed to two-sided layout; The module slot of lightning-protection module has terminal groove, the operating state of each module can be transferred to data acquisition process box, then transfers to monitoring outlay and rack LCDs by data acquisition process box, realizes Based Intelligent Control and detects in real time; There is LCDs at cabinet front cabinet door place, by the operating state of function button inquiry inner each road lightning-protection module.
Instrument signal lightning protection is independently a unit by the present invention, and unified monitoring manages, and is equivalent to thousands of lightning protection points to be integrated into a bit.Avoid the deficiency of common mounting means, make SPD wiring clear, install, safeguard easily convenient, cost-saving, effectively save space and the regular maintenance energy in control room.
