Description
Technical field
The invention belongs to the power supply lightning arrester, particularly a kind of multistage power supply lightning arrester.
Background technology
In Chinese patent " the big through-flow power arrester of combined type heavy load " (the ZL patent No. 01206146.8) literary composition; a kind of power arrester with secondary lightning protection circuit is disclosed; because the decoupling inductor of its buffer circuit is hollow coiling; inductance value is less, and the impedance that the impulse current that thunder and lightning is caused produces is still big inadequately.Its first order lightning protection circuit constitutes by the piezo-resistance of wanting five parallel connections at least or by big current drain pipe or by piezo-resistance series connection gas discharge tube; in parallel or the series connection of a plurality of arresting elements is used; under powerful impulse current effect, tend to take place the damage of avalanche type; so poor reliability; easily jump arc, the life-span is short.Be subjected to lightning impulse current can not surpass 100KA, the about 1000V of residual voltage, still higher.
Summary of the invention
Task of the present invention is that a kind of tolerance lightning impulse current of design is big, and residual voltage is little, does not jump arc, reliability height, a kind of multistage power supply lightning arrester that the life-span is long.
Technical solution of the present invention is a kind of multistage power supply lightning arrester of design, comprise power input, the power consumption equipment end, the lightning proof ground end, particularly between power input and power consumption equipment end, be connected reactor, first order lightning protection circuit is connected between power input and the lightning proof ground, is a kind of closed spark gap; Second level lightning protection circuit and third level lightning protection circuit all are connected between power consumption equipment end and the lightning proof ground.
The lightning-arrest safety circuit of the secondary that is connected between the power consumption equipment end of foregoing invention and the lightning proof ground is a kind of metallized film capacitor.
Three grades of lightning-arrest safety circuits that are connected between the power consumption equipment end of the invention described above and the lightning proof ground are a kind of Zinc-oxide piezoresistors.
The reactor of the invention described above has the magnetic core of high permeability.
All connecting lines of the invention described above.All adopt the big flat cable copper conductor of conducting capacity, terminals all use screw fastening.
The present invention has the following advantages: because the inductance value of reactor is big; the induction reactance height; can force most of lightning impulse current to be released via first order lightning protection circuit; the discharging current of the closed spark gap that is adopted is big; this device adds connecting path current capacity abundance, so can tolerate the above lightning impulse of 200KA.Simultaneously, also make the residual voltage that enters back level lightning protection circuit littler, also just can reduce the requirement of back level lightning protection circuit.Multistage lightning protection circuit makes the residual voltage of electricity consumption equipment end littler, can be low to moderate 800V, so can not produce the jumping arc, short circuit can not occur, has a power failure, and has improved reliability, has prolonged useful life, and is applied widely.
Description of drawings
Accompanying drawing 1 is a three stage power source lightning arrester electrical schematic diagram of the present invention.
Accompanying drawing 2, accompanying drawing 3 are secondary power supply lightning arrester electrical schematic diagrams of the present invention.
Embodiment
Below, in conjunction with the accompanying drawings, the present invention is elaborated.
Among Fig. 1, reactor 4 is connected between power input 5 and the power consumption equipment end 6, and first order lightning protection circuit 1 is connected between power input 5 and the lightning proof ground 7, is a kind of closed spark gap, has big discharging current.Second level lightning protection circuit 2 and third level lightning protection circuit 3 all are connected between power consumption equipment end 6 and the lightning proof ground 7, form the three stage power source lightning arrester.Thunder and lightning is formed huge pulse current on power transmission line; must at first in first order lightning protection circuit 1, release as far as possible; for this reason, reactor 4 should obtain big as far as possible inductance value under the least possible number of turns, so reactor 4 adopts the magnetic core of high permeability.This reactor 4 is controlled the pulse current that thunder and lightning produces with higher induction reactance, forces it to release at first in a large number in first order lightning protection circuit 1, thereby flows through the pulse current that reactor 4 arrives power consumption equipments 6 and greatly cut down.The closed spark gap can be released more than the lightning current 200KA.Arrive the lightening pulse voltage of power consumption equipment end 6, the AC metal film capacitor that at first is used as second level lightning protection circuit 2 absorbs, and further reduces the residual voltage of power consumption equipment end 6.If residual voltage has been lower than predetermined pressure sensitive voltage value, then the Zinc-oxide piezoresistor of third level lightning protection circuit 3 is not worked.If residual voltage still is higher than predetermined pressure sensitive voltage value, then Zinc-oxide piezoresistor is breakdown, and lightning current flows into lightning proof ground 7 by piezo-resistance rapidly, and the residual voltage of electricity consumption equipment end 6 is clamped in the predetermined safe scope, and this residual voltage can be low to moderate 800V.
Fig. 2 is the secondary power supply lightning arrester with lightning protection circuit 2.As mentioned above,, therefore only need remake once absorption, just can make the residual voltage of electricity consumption equipment end 6 be lower than the predetermined safe scope as the metallized film capacitor of lightning protection circuit 2 owing to the pulse current that flows through reactor 4 arrival power consumption equipment ends 6 is greatly cut down.
Fig. 3 is the secondary power supply lightning arrester with lightning protection circuit 3.Greatly cut down owing to flow through the pulse current of reactor 4 arrival power consumption equipment ends 6, therefore, only need remake once qualification, just can make the residual voltage of electricity consumption equipment end 6 be lower than the predetermined safe scope as the Zinc-oxide piezoresistor of lightning protection circuit 3.
For huge lightning impulse current can pass through this device safely, all connecting lines of the present invention all adopt the big flat cable copper conductor of conducting capacity, and binding post all uses screw fastening.
