Description
Technical field
The present invention relates to anti-thunder technical field, particularly relate to a kind of differentiated lightning protection method for communication base station and electric power system.
Background technology
Along with popularizing of 3G business, the outdoor version communication base stations such as communication base station, particularly high mountain, base station, field are built in a large number.Present stage, the lightning protection way generally adopted for communication base station and electric power system takes the aggregate measures such as protection direct lightning strike, supply line's protection, joint grounding, equipotential link.But; the key protection point of these traditional lightning protection measuress is not given prominence to, cause some circuits subjecting to be struck by lightning and equipment still higher by the ratio of broken by lightning, and the circuit that is struck by lightning is not subjected to for some and equipment implements overprotection; produce the wasting of resources, improve lightning protection cost.
Summary of the invention
The object of the invention is to the problem for prior art; a kind of differentiated lightning protection method for communication base station and electric power system is provided; the method is according to the complexity of being struck by lightning; three parts communication base station and electric power system are divided into carry out differentiation protection targetedly; thus ensure whole lightning protection measures effective protection communication base station and electric power system, and reduce lightning protection cost.
Differentiated lightning protection method for communication base station and electric power system of the present invention is that communication base station and electric power system is divided into three parts by function: AC power introducing portion, Control on Communication circuit part and transmission and reception holding wire, gps signal line part; Each several part is carried out respectively to the lightning protection of different stage.
Adopt piezo-resistance and gas discharge tube joint discharge method to AC power introducing portion, it is the part that whole base station power system subjects to be struck by lightning most that AC power is introduced, and therefore needs the protection of multistage too many levels.The method is between AC power and base station equipment, be connected with switch, slow fuse wire, the protection module be made up of piezo-resistance protecting network and gas discharge tube protective circuit, fast fuse wire in turn.AC power is connected with slow fuse wire by switch, and power supply input allows overcurrent in short-term, and slow fuse wire can improve the anti-interference of input element.Slow fuse wire one termination AC power, another termination piezo-resistance protecting network, piezo-resistance protecting network can suppress surge.Gas discharge tube protective circuit connects with piezo-resistance protecting network; gas discharge tube protective circuit works release Lightning Transient overcurrent and over-voltage effect; gas discharge tube protective circuit and piezo-resistance protecting network form multichannel protection side by side simultaneously, improve the reliability of lightning protection measures further.Fast fuse wire one end and piezo-resistance protective circuit, the other end is connected with base station equipment, and fast fuse wire is the afterbody protection before base station equipment; once electric current is excessive; fast fuse wire can quick-break, cuts off circuit, thus protecting group station equipment.
Gas discharge tube, piezo-resistance two-stage earial drainage method are adopted to Control on Communication circuit part.Specifically gas discharge tube protective circuit, resettable fuse and piezo-resistance protecting network are set between Control on Communication circuit and base station equipment.Control on Communication circuit is generally overhead transmission line, is also an emphasis of lightning protection, also uses the protection of three grades here.Control on Communication circuit connects with gas discharge tube protective circuit, and gas discharge tube protective circuit works release Lightning Transient overcurrent and over-voltage effect.Resettable fuse one end connects with gas discharge tube protective circuit, cuts off circuit, play lightning protection effect when resettable fuse can ensure that surge current is excessive, but after surge current release, automatically can recover, circuit is reruned.The other end of resettable fuse connects piezo-resistance protecting network, and piezo-resistance protecting network can suppress surge.The last access base station equipment of piezo-resistance protecting network.
Piezo-resistance protecting network is adopted to carry out lightning protection to transmission and reception holding wire, gps signal line part.Because transmission and reception holding wire, gps signal line are subject to effects of lightning little, link of protection is relatively less.Piezo-resistance protecting network one end connects with transmission and reception holding wire, gps signal line, and other end access base station equipment, piezo-resistance protecting network can suppress surge.Adopt the lightning protection measures simplified can reduce the cost of lightning protection facility for the module that thunder and lightning risk is little.
The present invention has following advantage:
In the present invention, the communication base station and electric power system thunder defending strategy of differentiation is conducive to the outfit that communication base station rationally effectively carries out lightning protection measures; the reinforced protection of multistage too many levels is taked for the circuit subjecting to be struck by lightning and equipment; the lightning protection device simplified is adopted for the circuit not subjecting to be struck by lightning and equipment; thus ensure whole lightning protection measures effective protection communication base station and electric power system, reduce lightning protection cost.
