The plug-type lightning protection voltage-limiting device has the advantages of reasonable design, simple structure and convenient installation and replacement, and capability of protecting connected electric equipment and facilities from being damaged when power lines are subjected to lightning high-voltage and the voltage of a power supply accidentally boosts. Besides, the plug-type lightning protection voltage-limiting device is safe and reliable, and solves the problem of lightning protection of indoor electric appliances.
Description
Technical field
The utility model relates to a kind of lightning protection pressure limiting device, specifically a kind of plug-type lightning protection pressure limiting device.
Background technology
In technique known, the electric power of all kinds of buildings such as most office building, residential building, market, hospital, communication line in inlet chamber after, supply socket, mobile porous socket and various 3-phase plugs etc. all do not have effective lightning protection, pressure limiting function.In case the outdoor lightning protection facility as first order protection breaks down; when running into the surge voltage that is occurred in thunder and lightning high pressure, the unexpected voltage rising of power supply, the power switch course of action; the voltage that moment raises can cause in various degree damage to all kinds of electric equipments, facility; light then cause the loss of property; heavy then can cause fire, have in addition can cause casualties.
The utility model content
Technical problem to be solved in the utility model provide a kind of reasonable in design, install to change easy, safe and reliable plug-type lightning protection pressure limiting device.
The utility model is to solve the problems of the technologies described above the technical scheme that is adopted to be: a kind of plug-type lightning protection pressure limiting device, conducting strip and the inclusion enclave that is arranged on the conducting strip are arranged, in inclusion enclave, be provided with lightning protection pressure limiting module, described lightning protection pressure limiting module is an inert gas filled insulating ceramics pipe in inside, in the insulating ceramics pipe, be provided with a central electrode and plural termination electrode, central electrode and termination electrode are made of alumina wafer and communicate with inert gas, and central electrode equates with arcing distance between each termination electrode.
Described alumina wafer is connected with conducting strip by lead.
The beneficial effects of the utility model are: have reasonable in design, simple in structure, install and to change advantage easily.Directly inserting the good socket of indoor ground connection can make the power supply in this zone have lightning protection pressure limiting function.It is very easy that replacing is installed, and need not to change original circuit.Plug-type lightning protection pressure limiting device of the present utility model also can directly be made the attaching plug of electrical equipment, has this regional lightning protection pressure limiting function of protection equally.When power circuit suffers that the unexpected voltage of thunder and lightning high pressure, power supply raises, occurred in the power switch course of action surge voltage; can discharge the high pressure surge on the power line over the ground; make voltage within moment drops to safe range less than setting; the electric equipment that connects with protection, facility etc. are not damaged; safe and reliable, solved the lightning protection problem of indoor electric appliance.

Mark among the figure: 1, inclusion enclave, 2, lightning protection pressure limiting module, 3, the insulating ceramics pipe, 4, central electrode, 5, termination electrode, 6, conducting strip, 7, alumina wafer.
Embodiment
As shown in Figure 1, a kind of plug-type lightning protection pressure limiting device, comprise conducting strip 6 and the inclusion enclave 1 that is arranged on the conducting strip 6, in inclusion enclave 1, be provided with lightning protection pressure limiting module 2, lightning protection pressure limiting module 2 is an inert gas filled insulating ceramics pipe 3 in inside, be provided with a central electrode 4 and two termination electrodes 5 in insulating ceramics pipe 3, central electrode 4 links to each other with a conducting strip 6 by lead respectively with termination electrode 5, and conducting strip 6 one ends expose in inclusion enclave 1 outside.
As shown in Figure 2, the central electrode 4 of lightning protection pressure limiting module 2 and termination electrode 5 are alumina wafer 7, and the inert gas in alumina wafer 7 and the insulating ceramics pipe 3 communicates, and by lead and 3 outside linking to each other of insulating ceramics pipe.Arcing distance between the alumina wafer of the alumina wafer of central electrode 4 and two termination electrodes 5 equates.Inert gas only serves as two discharge media between the alumina wafer as a kind of stable medium when electrion.This plug-type lightning protection pressure limiting device with two termination electrodes 5 is applicable to the AC power of two-phase three wire system.
As shown in Figure 3, for being applicable to the plug-type lightning protection pressure limiting device of three-phase four-wire system AC power, compare for implementing 1, it has three termination electrodes 5, all is connected to a conducting strip 6 on each electrode.
Plug-type lightning protection pressure limiting device of the present utility model can be used as indoor lightning protection device and uses, and directly uses as appliance plug after also can assembling connecting line.Be inserted into the good socket of original ground connection; the conducting strip 6 of central electrode 4 inserts the earth connection jack, and the conducting strip 6 of termination electrode 5 inserts power supply phase line jack, promptly becomes a small-sized lightning rod in this interchange zone; have the effect of being struck by lightning of preventing, can protect the safety of a plurality of electrical equipment simultaneously.Lightning protection pressure limiting module 2 is in off state under the normal condition, has high impedance.When power circuit suffers the thunder and lightning high pressure; the unexpected voltage of power supply raises; during the surge voltage that occurred in the power switch course of action; during the high pressure surge overshoot value that produces; the termination electrode 5 of lightning protection pressure limiting module 2 and the inert gas between the central electrode 4 be breakdown to carry out arc discharge; because arc voltage is very low; lightning protection pressure limiting module 2 becomes Low ESR by high impedance; off state originally becomes approximate short circuit; can in 0.1S, produce a large amount of discharging currents rapidly over the ground; high pressure surge on the power line is discharged over the ground; voltage was fallen within the safe range less than setting in moment; to protect back level electric equipment; facilities etc. are not damaged, and play lightning protection; the effect of pressure limiting.
