Abstract
Now there is no arrester special for BeiDou Satellite user receiver on the market, and lightning protection is realized only by installing two single antenna arresters on the signal radio frequency cable of the receiver and a power arrester in the power supply system of the receiver. In such a protection way, the arresters have too big size and are in separate installation, which is especially inapplicable to communication equipments on the vehicle. The utility model protects the signal receiving, signal sending of the BeiDou Satellite user receiver and two sets of power supply, and organically integrates the arresters, which is specially applicable to communication equipments on the vehicle, and the smaller size the better, can further enhance lightning protection of the lightning proof product to the BeiDou Satellite user receiver and enable the receiver to work more stably and reliably, can prevent damage from induction thunder in thunderstorm weather as well as interference from all electromagnetic fields and electromagnetic wave.
Description
Technical field
The utility model belongs to big-dipper satellite receiver user lightning arrester, is mainly used in protection big-dipper satellite receiver user exempts from thunder and lightning or other interference source in moving reception destruction, particularly radiofrequency signal lightning protection and power supply lightning protection.
Background technology
Also there be not the special-purpose lightning arrester of big-dipper satellite receiver user on the market at present; if people will solve the lightning protection of this equipment; can only be that two single antenna feeder arresters are installed on receiver signal radio frequency cable line, power arrester is installed at the power unit of receiver.Such protection causes the lightning arrester volume excessive, is again partial installation, is not suitable for the communication apparatus on vehicle-mounted especially.And big-dipper satellite receiver user lightning arrester of the present utility model is to the collection of letters of big-dipper satellite receiver user number, signals, and two groups of power supplys protect simultaneously, and organically lightning arrester is combined in one.Be specially adapted to the communication apparatus on vehicle-mounted, especially want the smaller the better occasion of cube.
Summary of the invention
It mainly is to solve the lightning protection of radiofrequency signal of big-dipper satellite receiver user and the lightning protection of power unit that the utility model belongs to big-dipper satellite receiver user lightning arrester.
Concrete technical scheme is: big-dipper satellite receiver user inside has received signal and the two groups of radio frequency cables that transmit, have simultaneously two groups of DC power supply again, so on the received signal radio frequency cable line of big-dipper satellite receiver user and the radio frequency cable line that transmits, two antenna feeder arresters are installed, and on two groups of DC power supply, are designed the DC power supply lightning arrester.Its antenna feeder arrester adopts gas discharge tube to make the thunder and lightning branch road and releases, or adopts the short-circuit line of 1/4 λ or high-frequency inductor line to make the thunder and lightning branch road and release, and its coaxial heart yearn can be straight-through, perhaps adopts high-frequency coupling electric capacity to come couples high frequency signals.
Power arrester adopts a plurality of piezo-resistance parallel connections of lamination to release, while a plurality of gas discharge tubes in parallel again, and the scope of the quantity in parallel of piezo-resistance is the 2-30 sheet, the quantitative range 2-30 of gas discharge tube props up.
The work indicating status of a plurality of expression lightning arresters and the indicator light indicator light of reaction lightning arrester indicating status behind the deterioration failure in lightning-arrest work are arranged on the casing.
By said structure and connected mode, further improved this lightning-protected product to big-dipper satellite receiver user lightning protection, make the more stable work of big-dipper satellite receiver user reliable.But the destruction of big-dipper satellite receiver user anti-induction thunder in thunderstorm weather, and various electromagnetic fields and electromagnetic interference.
Description of drawings
Below in conjunction with drawings and Examples the utility model is described further
Fig. 1. be circuit diagram of the present utility model;
Fig. 2. be product structure figure one of the present utility model;
Fig. 3. be product structure figure two of the present utility model.
As Fig. 1, Fig. 2, shown in Figure 3,1 is that input signal radio frequency cable end, 2 is that shell, 3 is that power lightning protection printed substrate, 4 is that antenna feeder arrester, 5 is that output signal radio frequency cable end, 6 is the power arrester relay indicating light.
Identical coaxial wideband antenna feeder arrester of received signal radio frequency cable line design at the big-dipper satellite receiver user with the receive frequency bandwidth; in like manner on the radio frequency cable line that transmits, design an identical coaxial wideband antenna feeder arrester with the tranmitting frequency bandwidth; its principle is when being responded to the invasion of thunder on the radio frequency cable line; the lightning protection component of antenna feeder arrester inside is with rapid triggering and conducting; the lightning overvoltage bypass is released; the safe operation of protection equipment; the attitude that restores to the original state does not rapidly again then influence the operate as normal of communication apparatus.Two groups of DC power supply lightning arresters of design on two groups of antenna powers of big-dipper satellite receiver user.Operation principle: mainly be to adopt a plurality of piezo-resistance stack technologies designs and in parallel with gas discharge tube, its objective is increase to the amount of releasing of thunder and lightning, make it have a plurality of branch roads of releasing, simultaneously high lightning voltage is limited the end.When two groups of DC power supply suffer that lightning overvoltage is invaded; the main lightning protection component piezo-resistance RV1 of DC power supply lightning arrester; RV2; RV3; RV4 will start conducting rapidly; lightning overvoltage is released, and the gas discharge tube in parallel with piezo-resistance limits the lightning overvoltage of high residual voltage get off again simultaneously, reaches the purpose of protection equipment.This product HL2 and HL4 is at work represented operating state, and HL1 and HL3 then react the indicating status of this lightning-protected product at the lightning protection deterioration failure.
By said structure and connected mode, further improved this lightning-protected product to big-dipper satellite receiver user lightning protection, make the more stable work of big-dipper satellite receiver user reliable.But the destruction of big-dipper satellite receiver user anti-induction thunder in thunderstorm weather, and various electromagnetic fields and electromagnetic interference.
