Description
Technical field
The utility model relates to a kind of GPS time service antenna of integrated lightning arrester, is used for communication base station and receives gps satellite signal, belongs to communication technique field.
Background technology
GPS time service antenna applications is in industries such as CDMA, TD-SCDMA mobile communication base station and satellite, power communications, for communication system provides clock sync signal.For ensureing clock sync signal, communication system has proposed high requirement to the stability of gps satellite signal.Receiving gps satellite signal need be installed in antenna on outdoor iron tower or the roof, causes that easily thunder and lightning punctures, and damages GPS time service antenna and causes inefficacy, normally moves thereby influence whole communication system.
In order to address this problem, generally take to install additional the way of lightning arrester on the Communication Engineering at GPS time service antenna port place, because being installed, GPS time service antenna belongs to outdoor work high above the ground, difficulty of construction is big, the joint at lightning arrester two ends all will be done waterproof protective and handle, and brings certain hidden danger for the stability of product.And stand-alone product of lightning arrester formation, itself adds operating expenses product, cost is very high.
Summary of the invention
The utility model is used to overcome the defective of prior art and a kind of GPS time service antenna that can anti-lightning strike, effectively protect the integrated lightning arrester of antenna internal module of providing.
The utility model is solved by following technical scheme:
A kind of GPS time service antenna of integrated lightning arrester is made up of radio frequency output/DC power supply port, RF Amplifier Module, power regulator module and lightning protection combinational circuit.
It is characterized in that: radio frequency output/DC power supply port links to each other with the lightning protection combinational circuit, and the lightning protection combinational circuit other end connects power regulator module, and RF Amplifier Module and lightning protection combinational circuit are connected in parallel on radio frequency output/DC power supply port simultaneously.
Above-mentioned lightning protection combinational circuit is made up of three grades of lightning protection components, and first order lightning protection component is the switching mode ceramic gas discharge tube, is used for absorbing the most of energy when being struck by lightning, and links to each other with radio frequency output/DC power supply port; Second and third grade lightning protection component is that transient voltage suppresses diode, links to each other other end ground connection with power regulator module; First order protective circuit adopts the independent grounding loop at its outside screening arrangement that increases, and when stoping it to absorb energy other device is caused radiation damage.This circuit module also comprises components and parts such as capacitance, decoupling capacitor, bias resistance.
The GPS time service antenna of above-mentioned integrated lightning arrester has been taken into account the characteristic of protecting big electric current, high voltage damage antenna device, has improved the response speed of integrated circuit to transient voltage, electric current simultaneously again.The GPS time service antenna of this structure can absorb the above transient state thunderbolt voltage of 10KV, effectively protects the antenna inner member.This lightning protection combinational circuit can repeat work, satisfies the requirement of shelter to thunder and lightning, can realize repeatedly protecting permanently effective protection antenna internal module; This antenna structure simplicity of design, be easy to miniaturization, and cost reduces greatly, be fit to produce in batches, on the basis that does not change primary antenna volume and installation form, reduced installation difficulty, improved overall reliability.
Description of drawings
Accompanying drawing is the GPS time service antenna circuit schematic diagram of a kind of integrated lightning arrester of the utility model.
Number in the figure is: 1, radio frequency output/DC power supply port; 2, RF Amplifier Module; 3, power regulator module; 4, switching mode ceramic gas discharge tube; 5(1,2), bias resistance; 6(1,2), capacitance and decoupling capacitor; 7, choke; 8(1,2), transient voltage suppresses diode.
Embodiment
The lightning protection combinational circuit is made up of three grades of lightning protection components, and first order lightning protection component is switching mode ceramic gas discharge tube (4), is used for absorbing the most of energy when being struck by lightning, and links to each other with radio frequency output/DC power supply port (1); Second and third grade lightning protection component is that transient voltage inhibition diode (8.1,8.2) links to each other other end ground connection with power regulator module (3); First order protective circuit adopts the independent grounding loop at its outside screening arrangement that increases, and when stoping it to absorb energy other device is caused radiation damage.This circuit module also comprises capacitance (6.1), decoupling capacitor (6.2), bias resistance components and parts such as (5.1,5.2).
Its operation principle is; when lightning waveform arrives port; transient voltage suppresses diode (8.1) and at first starts; because it is shorter that transient voltage suppresses the diode response time; having determined transient voltage to suppress diode at first starts; transient overvoltage is controlled at certain output voltage V c value (being maximum clamping voltage); because transient voltage suppresses diode (8.1; 8.2) moment vent discharge fail to be convened for lack of a quorum and go up to produce transient voltage Vu at bias resistance (5.2); when the voltage of transient voltage Vc+u reaches the moment starting resistor V of switching mode ceramic gas discharge tube (4); switching mode ceramic gas discharge tube (4) starts; big current drain is arrived ground; transient voltage suppresses diode (8.1; 8.2) effect of regulated output voltage arranged; this output voltage is far below the maximum withstand voltage of rear module, thereby plays the effect of protection rear end gps antenna module stability work.
Because GPS time service antenna is had relatively high expectations to stability, the utility model has been added the first class of protection circuit, requires lower GPS time service antenna can remove the one-level circuit for some lightning protection.Device parameters is selected and can suitably be adjusted resistance according to different demands.Because the utility model will drop to 5V with 10KV voltage in moment, so require to adopt high power device.
The utility model has passed through test of many times and on-the-spot Installation Validation, to the lightning Protection of GPS time service antenna with summary is installed has played very good effect.
After tested, the GPS time service antenna of the integrated lightning arrester of the utility model meets GB/T 18802.21-2004 idt
