Abstract
The invention consists of two lightning protection devices, a test control and warning circuit and two voltage-opened type switches. It features that two lightning protection devices are installed, but only one is used in work, and another one is in stand by state.
Description
Technical field
The present invention relates to a kind of lightning protection device, particularly relate to the device that carries out uninterrupted efficient lightning protection.
Background technology
Thunder and lightning is a kind of special weather phenomenon of aloft being discharged and being caused by charged cloud.According to interrelated data statistics, landing the voltage of thunder sometimes can be up to several ten million volt.Therefore, thunder and lightning causes very big threat for people's life and property safety.In some departments, especially at important departments such as electric power, communication, hospitals, it is very necessary carrying out uninterrupted lightning protection efficiently.
The device and the technical patent that are used for lightning protection at present are between power supply and equipment electric discharge device to be installed.This electric discharge device is made up of a plurality of discharge modules.After the module lightning protection function lost efficacy, checkout gear will send early warning signal, the module that prompting changing lost efficacy.When having thunderbolt to take place, discharge device can be released the high-tension electricity of thunder and lightning and induction, is issued to the purpose of lightning protection in the prerequisite of not interrupting device work.The subject matter of this method: discharge device mostly is consumable accessory, and after long-time use was aging, being subjected to thunderbolt will lose efficacy.At this problem, some patented technologies have proposed improved method.01258380), " a kind of multistage power supply lightning arrester " (patent No.: 03113996) and " Portable-power Lightning Protection Device " (patent No.: 03113908) mainly contains representational patent at present " a kind of lightning protection for power supply " (patent No.: is arranged.(patent No.: 01258380) adopt main discharge circuit and start-up circuit structure combining (Fig. 1) to form discharge module, wherein the main discharge circuit is by piezo-resistance VR for patent " a kind of lightning protection for power supply "
2With gas discharge tube G
1Be composed in series, start-up circuit is by piezo-resistance VR
1Form.Come effectively to improve the response speed of discharge module in this way, increase the service life.Patent " a kind of multistage power supply lightning arrester " improves the reliability of discharge device and prolongs its useful life by the multistage discharge circuit of design (Fig. 2).Wherein between power input (5) and power consumption equipment (6), connect reactor (4); first order lightning circuit protective circuit (1) is connected between power input (5) and the lightning proof ground (7); be a kind of closed spark gap, second level lightning circuit protective circuit (2) and third level lightning circuit protective circuit (3) all are connected between power consumption equipment (6) and the lightning proof ground (7).In patent " Portable-power Lightning Protection Device ", design special circuit (Fig. 3), comprise lightning protection circuit and the detection that is attached thereto, fault alarm circuit.Wherein lightning protection circuit 20 is common mode and differential mode lightning protection circuit commonly used, and warning circuit 30 comprises the automatic testing circuit 31 of fiery zero line polarity, the automatic testing circuit 32 of earth connection and lightning protection inefficacy acknowledge circuit 33.
From these existing patented technologies as can be seen, key issue does not solve.Though the life-span of discharge module has increased, but use or suffer strong thunderbolt for a long time, still can wear out and lose efficacy, even warning circuit gives a warning, under the situation that may also have follow-up thunderbolt, the maintenance personal can not emit life danger to remove in time to change discharge module, when can only wait until not thunderbolt safety, just can remove to change discharge module; Safeguard that accessory generally needs manufacturer to provide; need certain hour, and at this section in the period, equipment even personal safety there is not the protection of lightning protection device yet; still can be subjected to the very big threat of thunder and lightning, therefore a kind of lightning protection device that can realize uninterrupted efficient lightning protection function need be provided.
Summary of the invention
The present invention be directed to the specific (special) requirements of lightning protection reliability, and a kind of cost that provides is low, the shocking preventing technology of easily applying.
For achieving this end, the invention provides a kind of thunderstorm electricity protective device that can in good time change lightning protection component automatically.This lightning protection device is installed two lightning protection components, cover observing and controlling acknowledge circuit and two voltage open type automatic switches.

Embodiment
The present invention adopts following measure to realize the function of uninterrupted lightning protection.Principle as shown in Figure 4.Lightning protection device of the present invention mainly comprises five key components: two lightning protection components 1 and 4, each lightning protection component all comprises complete lightning protection circuit and the corresponding devices of a cover, all can independently finish the task of lightning protection, when work, only use a lightning protection component 1, another lightning protection component 4 is in stand-by state; The 5th, the observing and controlling acknowledge circuit, the automatic operating state that detects lightning protection component just in use, after its lightning protection function lost efficacy, this circuit will send early warning and change lightning-protection module; Two other critical component is that two voltage open type switches 2 and 3, two lightning protection components all are in on-state, controls selecting for use of lightning protection component by the mode that different cut-in voltages are set.When the cut-in voltage that is lower than lightning protection component 4 such as the cut-in voltage when lightning protection component 1 reaches certain value, when being subjected to being struck by lightning, most of lightning current can be released by lightning protection component 1, have only the sub-fraction lightning protection component 4 of flowing through to be released, like this, be equivalent to only use a lightning protection component during work, another lightning protection component is in stand-by state; After the lower lightning protection component of cut-in voltage lost efficacy, coupled automatic switch disconnected, and lightning current will be released by that higher lightning protection component 4 of cut-in voltage naturally, thereby realized the uninterrupted lightning protection to equipment.It should be noted that here the low value of cut-in voltage can not be too low, with the normal operation that guarantees protected circuit and avoid the aging rapidly of lightning protection component; The selection of the high value of cut-in voltage should make its residual voltage be no more than the puncture voltage of protected equipment; In addition, the difference between two cut-in voltage values also should be enough big, to guarantee that most of lightning current is only by that lower lightning protection component of cut-in voltage.
