Description
Technical field
The present invention relates to a kind of anti-lightning systems, and in particular to Integrated Automation System for Traction Substation anti-lightning system.
Background technique
Traction becomes, the general centralized arrangement of secondary device of distribution substation is in control room, and power station inlet wire and feeder line side are kept away
The Anti-surgings equipment such as thunder device, place are also disposed with lightning rod, and contact net uses integrated ground technology, and protective wire setting will expire as far as possible
Sufficient Anti-surging requirement.Live direct lightning strike can not directly be hit on secondary device, but induction lightening magnetic field impulse easily enters
The relatively weak secondary device of pressure resistance, anti-interference ability, causes equipment cisco unity malfunction or damage.By field research
And analysis, it is thunder and lightning wave energy that discovery, which causes the main reason for equipment damage and performance are destroyed after becoming, being struck by lightning with secondary device,
It is high and contain instantaneous high pressure spine wave, clutter, strong electromagnetic, surge are generated, high voltage, high current lead to electronic device performance
Damage is burnt down to individual component breakdown.
Summary of the invention
The technical problem to be solved by the present invention is to draw the secondary device of change, distribution substation at present will not directly be hit by lightning stroke
In, but it is subject to electric surge impact, electronic component failure is caused, and it is an object of the present invention to provide Integrated Automation System for Traction Substation

The linkage interface of subsystem and primary system.Different processing modes is taken respectively for two kinds of connection types above-mentioned,
Increase the method for surge protection device in each signal circuit for being directly accessed taking for electrical secondary system by connecting terminal
Processing, for not needing increase surge protection device then by Phototube Coupling terminal access electrical secondary system.Need to increase protection
The quantity of device is then determined according to the majority of external signal, is pacified in the protection screen of integrated system when external signal quantity is relatively more
When filling more crowded, need Surge Protector external separately installed, then be connected by cable with electrical secondary system.With reference to DL/T
5136-2012 specification, preferred cable shield two-terminal-grounding.
Further, the thunder and lightning intelligent management unit is provided with memory module, records each terminal by memory module
Surge frequency and time, personnel convenient for safeguarding be managed.Thunder and lightning intelligent management unit is responsible for managing live surge guarantor
The real time status of module is protected, itself has liquid crystal display and key, can inquire corresponding information on a display screen.Administrative unit is matched
There are 485 ports, data can be passed through to this port transmission to the working host of control room, to facilitate technical staff to the prison of equipment
Control.Simultaneously administrative unit be also equipped with failure output dry contact two it is right, link when having collected surge protection cell failure
Alarm.Intelligent management unit function is as follows: the number and the moment occurs every time that record surge occurs, data can inquire；Remote signalling is opened
Enter, the alarm of surge Module Fail；Remote signalling open into, record the number and time of origin of failed module, export dry contact alarm signal,
Data can inquire；Remote signalling is opened into intelligent management unit starts record and the inquiry of time and line duration；RS485 interface owns
Monitoring data can communicate upload, and energy multimode and company, and convenient long-range monitoring records lightning arrester discharge electric current；It can communications records
Or tele rcording.
The electric power loop uses the wideband power supply of 110-380V, according to DC power supply, DC power supply be 110V or
220V, according to AC/DC, then power supply is 220V or 380V.The various of the access of electric power loop can be guaranteed using the wideband power supply
Power supply can carry out applicable, improve its operation strategies, guarantee that device being capable of normal use.Firstly the need of become, distribution substation
Power of alterating and direct current system carries out Anti-surging design, configures necessary Anti-surging element, meets the requirement of releasing of main lightning current.Needle
To electrical secondary system, can be installed at microcomputer protecting device power input can reliably take shelter from the thunder, the phase of electromagnetism interference and power filter
Lightning-arrest device is closed, system global reliability is improved.Power lightning protection terminal is installed at the power supply introducing of integrated system, exchanges, is straight
Galvanic electricity source is installed respectively, three tunnel of direct current, exchanges two-way
Further, the junction of the GPS antenna and GPS device is protected by Surge Protector.GPS antenna peace
Mounted in the unobstructed place in roof, it is subject to surge invasion, needs to increase Surge Protector in GPS antenna and GPS device junction.
Optimally, the communication loop carries out lightning protection configuration according to different communication interfaces, when communication interface is Ethernet
When interface, at least need to configure seven Surge Protectors in interface, when communication interface is RS485 or RS232 interface, until
It is few to need to configure four Surge Protectors in interface.Optimally, it is comprehensive to be sent to TA21 by the order circuit for the data of acquisition
Close automated system.Do following configuration under normal circumstances: the communication interface of traction scheduling, electric power system dispatching and old mark system is
Ethernet interface needs to configure Ethernet Surge Protector seven, with the external equipments such as alternating current-direct current be generally RS485 or
RS232 interface, needs to configure four serial ports Surge Protectors, needs Ethernet interface with communications such as oil chromatographies, needs to configure one
A Surge Protector.
Embodiment two
