Description
Technical field
The fields such as component of machine technology, the communication technology are the utility model is related to, are that one kind is applied to electric power specifically
The downlead fastener of communication network steel tower.
Background technology
Communication, refer to the information interchange and transmission carried out between person to person or man and nature by certain behavior or medium, from
Referring broadly to the both sides for needing information or in many ways any means are used in the case of without prejudice to respective wish, any medium will
Information is accurately safely transmitted to another side from certain side.
Communication has different explanations in different environments, is communicated after there is Potential transmission communication
(Communication) by the single transmission for being construed to information, the transmission for referring to another enter row information from a ground with exchanging,
The purpose is to transmit message.However, communication is as the development of social productive forces is to transmitting message in human practice process
It is required that constantly lifting make it that human civilization is constantly progressive.In various communication modes, message is transmitted using " electricity "
Communication means is referred to as telecommunications (Telecommunication), this communication have the characteristics that it is rapid, accurate, reliable, and hardly
Limited, thus developed rapidly and extensive use by time, place, space, distance；Now because of the agility of electric wave
Communicated so that just constantly accumulating progressive material object with real economy with reference to cultural exchanges from Ancient people material exchange process
The obstruction of (postal ＆ communications) by human intelligible for restriction economic development.
In ancient times, the mankind are entered by modes such as post house, flying pigeon biography book, flames of war alarm, symbol, body language, expression in the eyes, touchings
Row information transmission.
In the horizontal rapid development of modern science, occur radio, landline telephone, mobile phone, internet in succession very
To the various communication modes such as visual telephone.The communication technology has furthered interpersonal distance, improves the efficiency of economy, deeply
Ground changes the life style and the social physiognomy of the mankind.
The beacon tower in the ancient times based on vision sound transmission, beat a drum, semaphore, modern age the post house based in kind transmit it is fast
Horse relay, homing pigeon, postal ＆ communications etc..Communication in the past takes the time of several days at the soonest for remote, and modern communicationses are past
Toward such as telegram, phone, express letter, short message, E-mail focus on instant messaging based on telecommunication modes, as postal for natural science
Political affairs communication can more embody man and nature harmony with link up, but now focus on economic interests in the period of often do not pay attention to people with
Natural relation causes postal ＆ communications to receive with respect to instant messaging.Definition of the Federal Communication method to communication includes telecommunications
And radio and television.It should be noted that this communication law is not appropriate for China.The humanity that China focuses on " harmony between man and nature " from ancient times is natural
See and pursue and get along amiably and peacefully between men.
Definition of the telecommunication supervising statute in China to telecommunications includes public telecommunication and radio and television.China《Postal law》
Without prejudice to《Universal Postal Convention》In the case of combine China's actual conditions constantly improve.
Communications optical cable (Communication Optical Fiber Cable) be by some (core) optical fiber (typically from
Several cores are to thousands of cores) the cable heart that forms and outer jacket formed.Optical fiber is compared with traditional symmetrical copper loop and coaxial copper loop
Compared with its transmission capacity is much bigger；Attenuation is few；Transmission range is grown；Small volume；It is in light weight；Without electromagnetic interference；Cost is low, is current
Most promising communications media.It is used widely in the signal transmission of all departments such as telecommunications, electric power, broadcast, will be by
Step turns into the main body of future communications network.Optical cable is in structure with cable primary difference is that optical cable must have stiffener to go to hold
By the mechanical load in the external world, to protect optical fiber from the influence of various outer mechanical forces.
Electric power networks (power network) are the parts in power system in addition to generating equipment and electrical equipment.Electricity
Power network includes 3 power transformation, transmission of electricity, distribution links.It is connected the power plant and electricity consumer that are distributed in wide region,
Send the electric energy of centralized production to the huge numbers of families of scattered electricity consumption.Electric power networks are mainly by power circuit, electric substation and current conversion station
(realizing the technique device that alternating current and direct current mutually convert) forms.It can be divided into transmission line of electricity, regional power grid, contact by function
Line and distribution network.Interconnection is used to realize the network interconnection, can rationally adjust interregional electric energy, improve power supply reliability and
Generating equipment utilization rate, the economy of Operation of Electric Systems, stability is set all to be improved.Though realize the network interconnection with big
Social and economic benefits, but its structure to power system, control measure, communications facility, traffic control etc. it is also proposed it is higher
It is required that.
Fastener is to be fastenedly connected with and apply extremely wide a kind of machine components.In various machineries, equipment, car
, ship, railway, bridge, building, structure, instrument, instrument, instrument and articles for use etc. above, it can be seen that miscellaneous tight
Firmware.Its feature is that description is various, and performance purposes is different, and standardization, seriation, unitized degree also pole
It is high.Therefore also a kind of fastener of obtained official standard is called standard fasteners, or referred to as standard component by someone.Fastener is
Most widely used mechanical basic part.With China's ranks of international trade big country of joining WTO and step into 2001.China fastens
