Description
Technical field
This utility model relates to a kind of graphite gaps surge protector.
Background technology
Along with the development of science and technology, the electric equipment that people are used gets more and more, and its internal structure is more and more accurate, quick
Sense.But due to reasons such as interfering with each other between the folding of power supply, in-plant thunderbolt, electric equipment, electric equipment
Holding wire often occurs surge, a kind of paroxysmal, extremely short but that peak value is the highest voltage of holding time.This high voltage pair
There is the biggest destructiveness in the components and parts in electric equipment.Therefore, people often use various types of surge protector to protect
Protect the electric equipment in circuit.Typically, for the convenience installed, safeguard, surge protector is modular construction form, by
Protection module and base are constituted, and protection module is plugged on base, are provided with protection circuit in protection module.There is a kind of graphite mould
Surge protector, graphite is made up of many lamellar spacings, and the lightning current of this kind of surge protector releases energy greatly (MJ level).But exist
Following defect: 1, graphite mould surge protector graphite flake in by lightning stroke process can damage thus cause surge protector to lose efficacy
With rupture；2, the static parameter of graphite mould surge protector is unstable.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of graphite gaps surge protector.
The technical scheme that this utility model solves above-mentioned technical problem is as follows:
A kind of graphite gaps surge protector, is arranged including in the housing being formed by connecting by upper cover and lower cover, described housing
Have graphite components and pcb board, in housing, be additionally provided with the first electrode and the second electrode, pcb board in the upper end of graphite components, described stone
Ink assembly is built up multilamellar interstitial structure by the combination of graphite flake and dead ring, and graphite components two ends be separately fixed at the first electrode and
On second electrode, each graphite flake is to earth terminal shunt capacitance.
The number of plies of described graphite flake is 3-10 layer.
The beneficial effects of the utility model are: this utility model solves owing to series connection graphite gaps starts high the asking of voltage
Topic (≤2kV).The advantage of product is, improves the through-current capability of surge protector, and due to series connection graphite flake it
Between a corresponding start-up capacitance device in parallel, so that the startup voltage of surge protector can be under control, and solve
The afterflow phenomenon that conventional general gap surge protector of having determined exists, and owing to the distance between graphite flake is the least, in action
Time equivalence shunt so not havinging the problem rushed down outside spark with one group of resistor coupled in parallel；And owing between each graphite being insulation
, and the physical property of graphite material is the most highly stable, so this surge protector does not exist short circuit and the phenomenon damaged.
Accompanying drawing explanation
Fig. 1 is this utility model population structure schematic diagram.
Fig. 2 is this utility model graphite components structural representation；
In accompanying drawing, the list of parts representated by each label is as follows:
1, upper cover；2, pcb board；3, the first electrode；4, graphite components；5, the second electrode 6, lower cover；41, graphite flake；42, exhausted
Edge ring.
Detailed description of the invention
Being described principle of the present utility model and feature below in conjunction with accompanying drawing, example is served only for explaining this practicality
Novel, it is not intended to limit scope of the present utility model.
As it is shown in figure 1, a kind of graphite gaps surge protector, the housing formed including upper cover 1 and lower cover 6, described housing
Inside being additionally provided with graphite components 4 and pcb board 2, as in figure 2 it is shown, L/N is phase line/zero line, PE is protecting field, and C is stone described in electric capacity
Ink assembly 4 is built up multilamellar interstitial structure by graphite flake 41 with dead ring 42 combination, and is fixed on the first electrode 3 and the second electrode 5
On, each graphite flake is to earth terminal shunt capacitance.
The number of plies of described graphite flake is 3-10 layer.
Described dead ring 31 is Teflon dead ring.
Embodiment
Graphite gaps surge protector is superimposed on by the high heat-resisting teflon spacer ring of 10 high energy disk graphite electrodes and 9
Constitute 9 layers of discharging gap together, it is ensured that the safe distance of every inner space and closure, be fixed in forging and stamping metal with bolt
On copper connecting plate, 8 gaps held an over the ground start-up capacitance device the most in parallel combines.Surge protector utilizes every
The clearance for insulation constituted between two panels graphite as discharging gap, surge protector entirety connect 9 such discharging gaps with
Reach high pass flow (Iimp50kA, Imax200kA)；But for overall surge protector, due to each discharging gap
Startup voltage be of a relatively high, so showing that the overall startup voltage of surge protector will be the highest, the most wherein 8
It is connected in parallel with a capacitor device between individual gap and is used as lighter, by the group in this group low ignition gap Yu one group of height ignition gap
Closing, low ignition gap starts (guarantee has a relatively low protection voltage), putting of the high ignition gap that ignites when relatively low voltage
Electricity (keeping big discharge capacity), solves owing to series connection graphite gaps starts the problem (≤2kV) that voltage is high.The advantage of product exists
In, improve the through-current capability of surge protector, and due to a corresponding startup in parallel between the graphite flake of series connection
Capacitor, so that the startup voltage of surge protector can be under control, and solve conventional general gap surge protect
Protect the afterflow phenomenon that device exists, and owing to the distance between graphite flake is the least, equivalence divides with one group of resistor coupled in parallel when action
Stream is not so havinging the problem rushed down outside spark；And owing between each graphite being insulation, and the physical property of graphite material
Can be the most highly stable, so considering that this surge protector does not exist short circuit and the phenomenon damaged from principle angle.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all in this practicality
Within novel spirit and principle, any modification, equivalent substitution and improvement etc. made, should be included in guarantor of the present utility model
Within the scope of protecting.
