Background technology
Automation system for the power network dispatching (EMS) is responsible for transformer station, the telemonitoring of power plant and wind field, the senior application work such as control and operation of power networks analysis; wherein the analog channel part of main station system is responsible for receiving the field apparatus operation information such as remote measurement, remote signalling, protection that each plant stand is sent; and send various data message and control command to each plant stand, in the normal operation of EMS system, play very important effect.Once analog channel breaks down, EMS system and electrical network power plant and substation's information just out of touch, will dispatcher be had a strong impact on to the judgement of whole operation of power networks state and control, also necessary dispatching command cannot be issued to the critical component of operation of power networks.
The analog channel part of automated system is made up of main station system, communication system and transformer substation system three parts, when treatment channel fault, first wants first failure judgement to be appear at which part, this need of work having come from ring by passage.Existing main website runs product and mainly contains two kinds from ring method, and one is carried out from ring at Wiring module clamping cable, and another is on Wiring module, use self-looped testing line.First method needs at module routing, if frequent routing is taken out stitches, is easy to make the copper sheet of Wiring module to loosen, causes permanent path deterioration; The second way is due to design problem, original channel line cable tie easily goes out by the short circuit head of self-looped testing cable after extracting Wiring module, if needed to different directions from ring, need to carry out from ring in different positions, therefore existing passage has been not suitable for fast and safely from ring detecting pattern diagnosis channel failure.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, a kind of automated system communications loop module is provided, substantially reduce EMS system channel fault handling time, for fast quick-recovery EMS system real time data provides strong technical support means.
Its technical scheme is: a kind of automated system communications loop module that the utility model is mentioned, comprise jumper switch, MAX202 chip, optical-electrical converter, jumper switch is arranged on signal input, output, signal of communication connects MAX202 chip by jumper switch, MAX202 chip is used for the reception process of signal as digital signal processing chip, and signal transacting is obtained the signal of telecommunication by optical-electrical converter by digital signal; Described jumper switch is electric brake loop, electric brake loop comprises 1-4 tetra-binding posts, the incoming end in electric brake loop is the 1st terminal and the 3rd terminal, the port of export in electric brake loop is the 2nd terminal and the 4th terminal, 2nd terminal connects Zener diode D1,4th terminal connects Zener diode D3, the two ends parallel diode D2 of the 2nd terminal and the 4th terminal and Zener diode D4, Zener diode D2 and Zener diode D4 connecting ring wire coil JP1 and JP2, ring wire coil JP1 and JP2 are by the 1st terminal and the 2nd terminal short circuit.
Above-mentioned Zener diode D1 series connection fuse F1, Zener diode D2 series connection fuse F2, Zener diode D3 series connection fuse F3, Zener diode D4 series connection fuse F4.
The beneficial effects of the utility model are: substantially reduce EMS system channel fault handling time, for fast quick-recovery EMS system real time data provides strong technical support means, for dispatcher's fast processing power grid accident provides strong basic data; Improve operating efficiency, also greatly reduce the time that dispatcher processes power grid accident, thus decrease the economic loss caused because of large-area power-cuts; Simplify channel loop testing process simultaneously, improve the science of automated system O&M means, enhance and the cooperating of fraternal business department, increasing efficiency by downsizing payrolls to realization serves impetus; And operating from ring of passage can be completed by the ring wire coil newly developed on channel service plate, not need frequent card line to connecting terminal block, improve the useful life of front-end system wire jumper module.
