Embodiment
The present invention provides a kind of tandem type electronic high voltage arrester, by multiple arrester single-stage components different electricity in series
Press the high voltage lightning-protection system of grade.Arrester single-stage component by two disc connection electrodes up and down, high-power TVS pipe array,
Epoxy glass fiber reinforced plastic cylinder and steam vent are constituted.One class large power TVS pipe array is coupled using the parallel connection of multiple TVS pipes to be formed, and is constituted single
Level lightning arrester assembly, then be simply in series by multiple single-stage components.
Below in conjunction with the accompanying drawings, the present invention is described in further detail.
As shown in Figure 1, this electronic high-voltage arrester uses series-mode frame, the protection voltage phase provided per one-level
Together, when needing to apply in different voltage class systems, Multi-stage lightning protector can be directly used in series.
As shown in Figure 2, single-stage component 6 is by two disc connection electrodes up and down（1、5）, high-power TVS pipe array 2,
Epoxy glass fiber reinforced plastic cylinder 4, steam vent 3 are constituted.Wherein two disc connection electrodes are made up of metal material up and down, big for connecting
Power TVS pipe array, while being also used for connecting external circuit.High-power TVS pipe array by multiple TVS diode connection in series-parallel and
Into TVS selection should follow following principle：TVS clamp voltage is not more than the maximum allowable safe voltage of protected element；
TVS surge forward current and the quantity product of TVS diode are not less than the size of lightning current；In the defined pulse duration
Interior, TVS peak-peak pulse power consumption have to be larger than the peak pulse power being likely to occur in protection circuit；Transient voltage presses down
Device processed can work between -55 ~+150 DEG C, and electronic high-voltage arrester of the present invention needs TVS in the temperature of a change
Spend work, due to its reverse leakage current be with temperature increase and increase, power consumption with TVS junction temperatures increase and decline, from+25 DEG C to+
175 DEG C, about linear decline 50%, breakdown voltage increases with temperature, so need to consider during selection TVS model using scene temperature
Influence of the degree change to its characteristic.Epoxy glass fiber reinforced plastic cylinder is used to close and protect high-power TVS pipe array.Epoxy glass fiber reinforced plastic cylinder side
Face is provided with steam vent, the heat produced during for discharging electronic high-voltage arrester work of the present invention in time.
When thunderbolt electronic high-voltage arrester of the present invention, lightning current, which flows through electronic high-voltage of the present invention, takes shelter from the thunder
Device, when multiple series-parallel TVS diode the two poles of the earth receive reverse transient state high energy impact events, with 10-12s magnitude velocities by its two
The high impedance of interpolar is changed into Low ESR, while absorbing the surge power that thunder and lightning is produced, makes the voltage clamp of two interpolars in a peace
The safe operation of total head, effectively protection transmission line of electricity.
