Abstract
The utility model relates to an isolator with surge protection function, which combines a lightning protection function with a signal isolating function into a whole. The isolator mainly comprises a lightning protection unit (1), an isolating unit (2) and a base (3); the components are in reliably electrical connection, and a signal circuit connected with the isolator realizes the lightning protection and the isolating functions. The utility model integrates various functions into a whole, reduces the attenuation in the signal transmission process, improves the transmission precision, reduces the cost and the volume, simplifies the installation, reduces fault points, saves the installation space and facilitates installation and maintenance.
Description
Technical field
The utility model relates to a kind of isolator, specifically relates to a kind of isolator that has surge protection.
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 control room 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 fault point 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.
The utility model content
In order effectively to overcome the above problems, the utility model proposes a kind of isolator that has surge protection.
The purpose of this utility model provides a kind of isolator that has surge protection, is applicable to various environment, and collection surge protection function, Signal Spacing are one, can realize lightning protection, Signal Spacing function.
The utility model is realized by the following technical solutions: the input at signal line is provided with lightning protection unit, on the product internal circuit board, isolated location is set, be electrically connected reliably, make to connect the function that the signal line of equipment has so far been realized lightning protection, isolation.The isolator that has surge protection mainly is made up of lightning protection unit (1), isolated location (2), base (3) etc.
It is characterized in that: signal line inserts by input unit (5), by the isolated location (2) on lightning protection unit (1) and the circuit board (4), is exported by output unit (6) successively.Utilize between input unit (5), lightning protection unit (1), the circuit board (4) and be electrically connected unit (7) and be electrically connected, and be electrically connected with guide rail (8), isolated location (2), output unit (6) are positioned on the circuit board (4), and are electrically connected reliably.The mode that lightning protection unit (1) adopt to be pegged graft is installed on the base (3), 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 (3) is provided with relay indicating light (9), and is electrically connected with circuit board (4).Be electrically connected unit (7) and be connected, as surge protection ground connection with guide rail (8).
The utility model product is compared with existing product, its advantage is: lightning protection, isolation features are integrated, reduced the decay in the signals transmission, improved transmission precision, adopt guide rail to be used for the installation of many set products, multiple function is integrated, has reduced cost, and volume reduces, simple installation, reduce the fault point, and saved installing space, is convenient to installation and maintenance.
