Description
Technical field
The present invention relates to a kind of power supply, particularly a kind of forest fire protection intelligent lightning protecting power supply.
Background technology
Wild environment is severe, and the power supply safety problem of equipment just seems particularly important.The safety of electric power system has crucial effect with stable to the success or failure of engineering.Thunder and lightning is as the important threat of field equipment, and how lightning protection becomes our problem in the urgent need to address.As a kind of natural phenomena, thundercloud is that the globule fallen rubs mutually, producing electrostatic makes anion dissociate to the globule surface suspended and form electronegative cloud, the main discharge phase of thunder and lightning, discharge channel flows through the electric current of amplitude hundreds of kilo-ampere, is the Main Stage causing Lightning Disaster, when it hits transmission line, form direct lightning strike overvoltage or the lightning induced voltage of very high potential, cause the infringement to power supply unit, interrupt or affect the normal work of whole system.
Forest fire protection image monitoring equipment and power supply unit thereof are loaded on mountain top more, but mountain top is again thunder and lightning mostly occurs area, in order to ensure the work of forest fire protection power supply unit safety and stability, the design a whole set of electric power system being carried out to effective lightning protection is absolutely necessary.
In existing shocking preventing technology; except traditional lightning rod draws thunder Interception Technology; having reduction of dissipating, having shielded isolation, having suppressed shunting, having dredged balanced equipotential, optimization ground connection releases and the technology such as early warning are located in thunder and lightning detection; and correspondingly develop equipment, the device and products such as multiple high-tech spacer assembly, surge protector, efficient corrosion resisting resistance reducing agent, this is all that effectively defence is administered Lightning Disaster and established technology and material base.But, to the communications tower on high mountain or fire tower, the monitoring whistle etc. arranges lightning protection, lightning-arrest poor effect.Be specially: communications tower or fire tower, the whistle is provided with microelectronic device in monitoring, fire prevention The Cloud Terrace on such as, satellite pot fire tower in communications tower is accurate microelectronic device, by thunderbolt very easily with bad, and, lightning rods etc. are when direct lightning strike inductance is excessive, led off slow, and caused the damage of microelectronic device, cause heavy losses.
Traditional forest fire protection electric supply installation is all simple power supply, or takes shelter from the thunder in conjunction with lightning rod; Do not carry out the lightning-arrest of science, the comparatively safe of equipment can not be ensured.So, on thunderbolt ratio mountain top, field more frequently, at the cut-out power supply of the instantly safe of thunderbolt, thus forest fire protection monitoring equipment is carried out isolating become a kind of urgent demand in the moment of lightening strikes and power supply link, in addition, mountain top bad environments, the cost that uses manpower and material resources sparingly that the automatic recovery of the power supply after thunder and lightning can be very large, this is a development prospect.
For realizing the better protection of forest fire protection monitoring equipment, there is the lightning protection proposed by having certain blocking-up property, realizing power-off when being struck by lightning by burning this equipment; Have and propose to use active isolation device, before predictable thunder and lightning arrives, the connection of power supply link and forest fire protection monitoring equipment is directly disconnected by communication measure, make equipment be in power-off or UPS power supply state temporarily, the electromagnetic induction thunder that link appendix is powerful even if power like this, also nucleus equipment can not be caused to suffer powerful rush of current, avoid device damage; But above method all can not meet the requirement of forest fire protection monitoring equipment round-the-clock monitoring forest, can not better meet the requirement of field of forest fire prevention.Therefore; simple in the urgent need to there is a kind of structure; easy to use; good stability; can Timeliness coverage thunder-strike phenomenon; and accuracy rate is high, thus protection load equipment can avoid the phenomenons such as thunderbolt to the infringement of load equipment, thus the method reaching proterctive equipment, reduce maintenance cost, improve the object of device security.
