Description
Technical field
The utility model relates to a kind of automatic weather station signal line lightning arrester.
Background technology
At present, domestic automatic weather station is popularized rapidly, and the website distribution is wide, and the phenomenon that automatic weather station equipment damages because of thunder and lightning takes place frequent, but also unspecial special-purpose lightning arrester at the automatic weather station signal system.Automatic weather station mainly utilizes the sensor acquisition signal to each meteorological element, by collector and microsystem data are handled then, the automaticity height, in this system, very responsive to all kinds of electromagnetic interference, be easy to cause that because of thunder and lightning or other electromagnetic pulse equipment work is undesired, make loss of data, distortion, even causing device damage to cause the data acquisition interruption, its loss can't remedy.In addition, representative for the meteorological element that makes collection, weather station is generally built spacious relatively position in, does not have other tall and big object on every side and blocks, and in such environment, the probability that equipment is struck by lightning increases.
Statistical analysis by inquiry, automatic weather station equipment thunderbolt source of damage major part is because thunder and lightning causes its damage by supply line and sensor signal lines intrusion equipment, general weather station is installed lightning protection device and is implemented easily in its supply line, but in the meteorological element acquisition system, because signal line is many, the transducer sensitivity height, it is very inconvenient that lightning protection device is installed on each holding wire separately, and make data acquisition inaccurate easily, influence certainty of measurement.Domestic not specially at the special-purpose lightning protection device of automatic weather station signal line, this lightning protection device is succeeded in developing and can be filled up this blank.
Summary of the invention
The purpose of this utility model is at above-mentioned present situation, aims to provide that a kind of discharge capacity is big, the response time is fast, the low automatic weather station signal line lightning arrester convenient for installation and maintenance of residual voltage.
The implementation of the utility model purpose is, automatic weather station signal line lightning arrester, and lightning arrester one end is connected with each meteorological element data sampling sensor, and an end is connected with the induced signal interface of automatic weather station collector, and concrete method of attachment is:
1 of rain sensor interface, 2,3 pins are by the inductance L in the lightning arrester, piezo-resistance MOV, gas discharge tube GDT and Transient Suppression Diode TVS connect 1 of rainfall induced signal collector interface, 2,3 pins, temperature, 1 of humidity sensor interface, 2,3,4,13,14,16 pins are by the gas discharge tube GDT in the lightning arrester, decoupling resistance R, piezo-resistance MOV and Transient Suppression Diode TVS connect temperature, 1 of humidity inductive signal picker interface, 2,3,4,13,14,16 pins, the top layer, shallow-layer, 1 of deep ground temperature sensor interface, 2,3,5,6,7,9,10,11,13,14,15,17,18,19 pins are by the gas discharge tube GDT in the lightning arrester, decoupling resistance R and Transient Suppression Diode TVS connect the top layer, shallow-layer, 1 of deep ground temperature induced signal collector interface, 2,3,5,6,7,9,10,11,13,14,15,17,18,19 pins, wind direction, 1 of air velocity transducer interface, 2,3,4,5,6,7,9,10,11,12,8 pins are by the gas discharge tube GDT in the lightning arrester, inductance L, piezo-resistance MOV and Transient Suppression Diode TVS give a dinner for a visitor from afar to, 1 of wind speed induced signal collector interface, 2,3,4,5,6,7,9,10,11,12,8 pins.The utility model can be concentrated protection to the intrusion of thunder and lightning on the signal line of meteorological elements such as wind direction, wind speed, rainfall, humiture, top layer ground temperature, shallow earth, deep ground temperature, avoid collector to be struck by lightning, have that discharge capacity is big, the response time is fast, residual voltage is low, data collection transmission is not had influence, characteristics convenient for installation and maintenance.

Embodiment
With reference to Fig. 1, lightning arrester one end of the present utility model is connected with each meteorological element data sampling sensor, and an end is connected with the induced signal interface of automatic weather station collector.Each meteorological element data sampling sensor, automatic weather station collector are the general transducer of present meteorological department, collector.
With reference to Fig. 2, the rain sensor in each meteorological element data sampling sensor of the present utility model, temperature, humidity sensor, top layer, shallow-layer, deep ground temperature transducer, wind direction, air velocity transducer are by rainfall signaling interface, temperature, moisture signal interface, top layer, shallow-layer, deep ground temperature signaling interface, wind direction, wind velocity signal interface in the induced signal interface of inductance L, piezo-resistance MOV, gas discharge tube GDT, Transient Suppression Diode TVS or decoupling resistance R tap automatic weather station collector in the lightning arrester.
Lightning protection device is a series-mode frame, and internal circuit adopts two-stage shunting, voltage-limiting protection mode, integrates that high energy is released, current limliting and clamper function.Under the normal operation, the internal lighting protection element is the high-impedance state no current to be passed through, as thunderbolt or other overvoltage when passing through, gas discharge tube GDT that first order discharge capacity is bigger or the rapid conducting of piezo-resistance MOV are low resistive state, because the effect of decoupling resistance R or inductance L leaks into the earth with most of lightning current by this level, when thunder and lightning process gas discharge tube GDT or piezo-resistance MOV, still have bigger residual voltage at its two ends, equipment can not be born.The Transient Suppression Diode TVS that the second level employing response time is exceedingly fast can be limited in the residual voltage that the first order produces in the scope of equipment permission through the further earial drainage of this grade, pressure limiting.
This thunder resisting equipment is installed, thunder resisting equipment ground wire and lightning protection earth mat should be done reliably to be connected.
The utility model is an inactive component, generally need not safeguard, can use for many years.When because of thunderbolt or other reason when causing collector work undesired, can remove lightning protection device, recover the former mode of connection, illustrate then that lightning protection device damages and should give maintenance or change as collector is working properly, guarantee the continuity of equipment lightning protection.
