Background technology
Thunder and lightning is the major reason that causes electronic equipment to damage, in industrial automation system, the long or many places of signal transmission line between field instrument equipment and the pulpit equipment are in the more abominable place of outdoor environment, the terminal device of the lightning surge of Chan Shenging or other disturbing pulse road along the line transmitted in both directions invasion on the line, and cause the unusual even damage of equipment work.Though being installed, the circuit of signal isolator can prevent that some signals from disturbing, but interference for the thunder and lightning generation, signal isolator can not suppress, and itself very easily suffers the infringement of lightning surge and lost efficacy, thereby causes the signal line transmission to interrupt or the damage of circuit terminal device.Therefore, systematically lightning protection and anti-interference particularly crucial.
At present; at the anti-interference measure of taking of the lightning protection in the automated system is that the disturbing pulse of installing on the line under the signal isolator inhibition normal condition influences circuit; signal isolator itself can not disturb by lightning impulse resistance, needs to install on the line simultaneously Surge Protector and damages signal isolator and system equipment to prevent lightning surge road along the line transmission.The problem that above measure exists is: 1, existing signal isolator can only be isolated normal pulsed in the signal and interference; surge currents such as Lightning Electromagnetic Pulse can not be isolated or filtering; when suffering Lightning Electromagnetic Pulse; very easily damaged and caused protecting actual effect or signal interruption; and might cause device damage, Surge Protector must be installed simultaneously.2, signal isolator and Surge Protector are installed on the line simultaneously, have been increased the wiring point in the circuit and the decay of line signal, wiring unreliable causes easily then that the circuit transmission is interrupted, system's instability, and just the trouble spot increases.3, two kinds of equipment are installed on the line, have been increased installation cost and difficulty, also taken installing space simultaneously, make troubles for construction and maintenance.4, existing signal isolator and distributor are difficult to mutual conversion, and be relatively poor for the adaptability of on-the-spot varying environment.
The utility model content
In order effectively to overcome the above problems, the utility model proposes a kind of signal isolation distributor that has surge protection.
The purpose of this utility model provides a kind of signal isolation distributor that has surge protection, is applicable to various environment, and collection surge protection function, Signal Spacing, distribution are one, can realize functions such as lightning protection, the isolation of signal photoelectricity, signal allocation, distribution.
The utility model is realized by the following technical solutions: the input end at signal line is provided with lightning protection unit, photoelectricity isolated location, power supply unit, signal distribution unit are set on the product internal circuit board, each several part is electrically connected reliably, makes to connect the function that the signal line of equipment has so far been realized lightning protection, isolation, distribution, distribution.The signal isolation distributor that has surge protection mainly is made up of lightning protection unit (1), photoelectricity isolated location (2), power supply unit (3), signal distribution unit (4), base (5) etc.
It is characterized in that: signal line inserts by input block (7), by photoelectricity isolated location (2), power supply unit (3), signal distribution unit (4) on lightning protection unit (1) and the circuit board (6), is exported by output unit (8) successively.Utilize between input block (7), lightning protection unit (1), the circuit board (6) and be electrically connected unit (9) and be electrically connected, and be electrically connected with guide rail (10), photoelectricity isolated location (2), power supply unit (3), signal distribution unit (4), output unit (8) are positioned on the circuit board (6), and are electrically connected reliably.The mode that lightning protection unit (1) adopt to be pegged graft is installed on the base (5), and lightning protection unit (1) be a hot plug device, and promptly lightning protection unit (1) is in the process of plug or all can not cause the interruption of signal after plugging.Base (5) is provided with relay indicating light (11) and distribution selected cell (12), and is electrically connected with circuit board (6).Distribution selected cell (12) can be realized the realization of power supply unit (3) function, if distribution selected cell (12) position for opening, then has distributing function, otherwise then do not have.Be electrically connected unit (9) and be connected, can realize that the distribution power supply from guide rail (10) input, is convenient to the installation side by side of signal isolation distributor with guide rail (10).
The utility model product is compared with existing product, its advantage is: lightning protection, the isolation of signal photoelectricity, signal allocation, distributing function are integrated, reduced the decay in the signals transmission, improved transmission precision, adopt guide rail to carry out the input of distribution power supply, be convenient to the installation of many set products, selectable distributing function is suitable for the application under the various varying environments, multiple function is integrated, has reduced cost, and volume reduces, simple installation, reduce the trouble spot, and saved installing space, is convenient to installation and maintenance.
