Abstract
The utility model provides an all solid state transmitter lightning protector, which comprises an all solid state transmitter, an antenna and feeder line as well as an allotting network and a transmitting antenna which are respectively connected with the transmitter, and a discharge ball, an anti-lightning inductance and a graphite discharge arrester which are respectively arranged at the end of the transmitting antenna. The utility model is characterized in that: one end of a parallel resonance device consisting of an inductor and a capacitor is connected with the output end of the transmitter, while the other end of the parallel resonance device is connected with the ground. The utility model can cause resonant frequency to be high-impedance, and can cause the harmonic wave outside the resonant frequency and the DC component to be low-impedance, and timely leak by connecting to the ground, thereby effectively filtering out the clutter lightning components outside the resonant frequency, and protecting the uninterrupted, safe and reliable broadcasting of the transmitter, namely achieving the zero-second broadcasting. The utility model not only has reliable anti-lightning function but also has the advantages of low cost, easy installation, obvious effect, etc., and also facilitates improving the overall performance and technical indicators of the transmitter. Therefore the utility model is an ideal, safe and reliable dedicated anti-lightning device for the transmitter.
Description
Utility model relates to a kind of lightning protection device, especially a kind of lightning protection device that can be used on the medium wave all solid-state transmitter.
Characteristics such as all solid-state transmitter is efficient so that himself was had, performance index are superior are just progressively eliminated original vacuum tube transmitter, are widely used in the broadcasting industry.Its appearance has not only improved the fail safe and the reliability of broadcasting, and can effectively do uninterrupted broadcast, so that important or up-to-date message is sent to huge numbers of families immediately.In actual applications; for avoiding all solid-state transmitter attacked by thunder and lightning; though be provided with multiple defense protection facilities such as ball discharge, lightning protection inductance, graphic discharge device at the transmitting antenna end, but still have the part lightning current to enter transmitter, make it cisco unity malfunction by antenna-feedback system.
The purpose of this utility model is to overcome the deficiency of prior art, provides a kind of effectively filtering other clutter thunder and lightning composition, all solid-state transmitter lightning protection device of protection transmitter non-stop run.
The utility model is realized by following technical proposal: it comprises all solid-state transmitter, antenna feeder, allotting network and transmitting antenna that links to each other with this transmitter and the ball discharge that is installed in the transmitting antenna end, lightning protection inductance, graphic discharge device, an end that it is characterized in that the parallel resonance device that is made of inductance and electric capacity is connected other end ground connection with the transmitter output.
The inductance value of described parallel resonance device is 38.1 microhenrys (μ H), and capacitance is 2000 picofarads (PF).
Resonance frequency (the f of described parallel resonance device
0) frequency of launching with all solid-state transmitter is identical, (f
0) be 576 KHz (KHz).
The utility model compared with prior art has following advantage and effect: owing to be provided with the parallel resonance device at the transmitter output; both can make resonance frequency be high impedance; and the loss minimum of resonance frequency; can make the resonance frequency humorous flip-flop that involves in addition be Low ESR again; and in time leak over the ground; thereby the clutter thunder and lightning composition beyond can effectively filtering resonance frequency,, safety uninterrupted, broadcast reliably, thereby guarantee that its zero second broadcasts with the protection transmitter.Characteristics such as the utility model not only has reliable lightning protection function, but also has low, the easy installation of cost, and effect is remarkable also help the combination property that improves transmitter simultaneously, and technical indicator, are a desirable safe and reliable special-purpose lightning protection device of transmitter in fact.
Fig. 1 is the circuit structure diagram of the utility model.
Below in conjunction with accompanying drawing the utility model is described further.
Among the figure, 1 is transmitting antenna, be connected with ball discharge 2, lightning protection inductance 3, graphic discharge device 4 on it, 5 is allotting network, link to each other with feeder line 6 with transmitting antenna 1 respectively, 6 is feeder line, and 7 is the parallel resonance device, one end ground connection, the other end links to each other with the output of all solid-state transmitter 8,71 for constituting the electric capacity of parallel resonance device, and its capacitance is 2000 picofarads (PF), and 72 for constituting the inductance of parallel resonance device, its inductance value is 38.1 microhenrys (μ H), 8 is all solid-state transmitter, and its power is 10KW, and tranmitting frequency is 576 KHz (KHz).
Claims (3)
1, a kind of all solid-state transmitter lightning protection device, comprise all solid-state transmitter, antenna feeder, allotting network and transmitting antenna that links to each other with this transmitter and the ball discharge that is installed in the transmitting antenna end, lightning protection inductance, graphic discharge device, an end that it is characterized in that the parallel resonance device that is made of inductance and electric capacity is connected other end ground connection with the transmitter output.
