Description
Technical field
The utility model relates to surge protection technical fields, and in particular to a kind of disengaged surge protector of intelligence.
Background technique
Current lightning protection market both at home and abroad, before being typically employed in surge protector (SPD, Surge ProtectiveDevice)
End is installed in series regular circuit breakers (mostly select DZ47 miniature circuit breaker), or is installed in series fusing in surge protector front end
Device.It is installed in series breaker for surge protector front end, because circuit breaker internal major loop coil inductance acts on, is there is lightning stroke
When overvoltage, meeting causes entire lightning protection to protect in the residual voltage that the generation of breaker both ends is more than 1000V, this residual voltage after being superimposed upon on SPD
The total level of protection decline for protecting circuit, is unfavorable for equipment safety operation, or even directly equipment is caused to be damaged, influences entire power distribution system
The safety of system；In SPD exception puncture short, this power current is insufficient to allow breaker immediate trip, and SPD is directly on fire at this time
Or explosion；Though or as power current rising can cause to trip, SPD has burnt or has exploded before tripping, influences entirely to match
The safety of electric system.
For being installed in series fuse in surge protector front end, in SPD puncture short, this power current is insufficient to allow
Fuse is instanteously blown, and SPD is directly on fire at this time or explodes；Or as though power current rising can cause fuse blows,
SPD has burnt or has exploded before fusing, influences the safety of entire distribution system.
Meanwhile if breaker and fuse value are small, such as 3A, when there is power frequency overcurrent, can play tripping or
Fusing effect, (actually various scene lightning stroke overcurrent are greater than 20kA or more, individual places mostly when having lightning stroke overcurrent
100kA or more can be reached), breaker can thread off at this time, and fuse can also fuse, and lightning protection effect just be lost, to various
It needs for equipment to be protected to be fatal.If breaker fuse of not threading off does not fuse when first ensuring that lightning stroke overcurrent,
The value of breaker and fuse will be very big, even more than the capacity of master switch, for example the SPD of Imax 40kA will be selected
125A, so big value, reaching 600A or more when there is power frequency overcurrent it is necessary to moment can thread off or fuse rapidly,
It has caused and has burnt or fire incident at this time.In addition, there is also the problems that inductance causes Up excessively high for breaker.
Comparatively safe way is to install the dedicated disconnector of surge protector (SSD) in surge protector front end, this kind is done
Method is only suitable only for reliably being detached from surge protector near short circuit failure, equal for power frequency overcurrent and resistive short
Safety cannot be played timely to be detached from.
In addition, either what device surge protector front end installs, it is required to reserve sufficiently large space, and in reality
It also needs virtually to increase difficulty of construction using cable consumptive material and reduce protecting effect in the installation of border.
