Description
Technical field
Patent of the present invention relates to a kind of gas-discharge tube being applied to power-supply system lightning Protection.
Background technology
Being currently recorded in the thunderstorm number of times of case and compared before 10 years and about have more twice, protection people and electrical equipment have become increasingly important from voltage surge impact.In this field, in addition to ensureing the life of people, more technical scheme concentrates on and ensures on the good of electric device and continuous service.Lightning-arrest district based on VDE V 0185 Part IV principle, IEC 61643-11 antithetical phrase power distribution network (ii level) and terminal (the IIIth grade), the gas-discharge tube of building entrance (the Ith grade) has done specification restriction.Gas-discharge tube early has been widely used for the protection of protection equipment, sub-power distribution network and building entrance zero line (NPE) over the ground.Owing to zero line is protected the requirement to product afterflow ability the highest by building entrance live wire; up to now; the protection of the Ith grade of L-N would generally be with some models the most diversified traditional type the air gap; it is used for one sometimes guaranteeing that the complicated circuit that triggers of protection level combines, belongs to spark gap category.Mainly have the disadvantage that
1, voltage protection level is higher than 3000V；
2, unstable properties during service life, open gap easy climate environment and pollution effect；
3, there is splashing flame or shock wave during work；
4 and peripheral devices or equipment have mounting distance requirement；
5, extra triggering circuit is needed, by auxiliary device blow-out.
For overcoming in prior art the not enough problem of open the air gap, the solution of tradition confining gas discharge tube be multiple gas-discharge tubes of connecting to improve arc voltage, thus reach to interdict the effect of afterflow.But owing to traditional design monolayer arc voltage only has about 18V (this is determined) by gas discharge principle, the arc voltage of 270V to be reached needs 15 mono layer gas discharge tubes of connecting, whether from the point of view of cost or volume, the market demand all cannot be met.For solving this problem, there is the mode of some products employing monolayer discharge tube built-in multilamellar discharging gap in the market to improve arc voltage, thus reduce cost and the volume of product.But from the point of view of actual effect, the problem of sideflash between gap, arc voltage and afterflow ability still cannot be avoided to increase limited, it is impossible to spread uses.
Typical products 1: internal structure is as it is shown on figure 3, have 16 discharging gaps in middle one layer of discharge tube, but its arc voltage only has 48V, from sideflash under big current conditions, causes that in-built electrical pole piece edge is exothermic melting to lose efficacy together.
Typical products 2: internal structure is as shown in Figure 4, three discharging gaps are had in monolayer discharge tube, but its arc voltage only has 42V, under big current conditions, intermediate space is discharged from middle part, not the most then discharging from electrode edge (side) due to creep distance in two other gap, causes that in-built electrical pole piece edge is exothermic melting to lose efficacy together.
Summary of the invention
An object of the present invention is to provide the porcelain tube with multiple step；It is a further object to provide a kind of utilize this multi-step porcelain tube have that arc voltage is high, afterflow ability strong, stable performance, volume is little, install simple multi-layer gas discharge tube.
The object of the present invention is achieved like this: a kind of multi-step porcelain tube, including porcelain tube body, is provided with multiple step in porcelain tube body.
A kind of multi-layer gas discharge tube, the step of multi-step porcelain tube is provided with the first sparking electrode and the second sparking electrode, isolation ceramics is set between the first sparking electrode and the second sparking electrode, in the chamber that two the second sparking electrodes and porcelain tube body are formed, it is filled with inertia and non-inert mixed gas, and forms three layers of discharging gap.
The tolerance regardless of the second sparking electrode and isolating ceramics and position, the design of multi-step porcelain tube and isolation ceramics can guarantee that electric discharge only occurs in the center of sparking electrode rather than at the edge of sparking electrode.
Multi-step porcelain tube that the present invention provides and utilize the gas-discharge tube that multi-step porcelain tube makes, owing to have employed the porcelain tube of the multiple ledge structure of indoor design, effectively increase creep distance between gap, avoid marginal discharge between gap, thus ensure to exist three independent discharging gaps in monolayer discharge tube, arc voltage is improved exponentially, and the arc voltage of monolayer reaches 65V, and afterflow ability is greatly enhanced.
Have employed in the porcelain tube of the multiple ledge structure of indoor design can ensure monolayer discharge tube and have multiple independent discharging gap, discharge from main gap under big current conditions.The tolerance regardless of the second sparking electrode and isolating ceramics and position, the design of multi-step porcelain tube and isolation ceramics can guarantee that electric discharge only occurs in the center of sparking electrode rather than at the edge of sparking electrode.
Under usual condition, discharge tube is applied to power supply L-N protection, and in addition to being subjected to direct thunder (10/350us waveform modelling) impact, maximum problem is to must be able to effectively interdict afterflow, and according to safety requirement, 32A sky is opened and can not be beated.This means that discharge tube solution must have sufficiently high arc voltage (270V), conventional monolayers discharge tube arc voltage to only have about 18V, it is necessary at least 15 mono layer gas discharge tubes of connecting, and be all not allow from the point of view of cost and installing space.The technical scheme that the present invention provides, under conditions of not changing mono layer gas discharge tube volume, built-in 3 layers of active discharge gap, the arc voltage of monolayer discharge tube is improved about 4 times, 4 layers just be enough to solve afterflow and the empty problem opening jumping, make discharge tube be applied to power supply LN protection to be possibly realized, and all have at reliability, cost and aspect of performance and have great advantage.
