Description
Technical field
This utility model relates to spark gap field, particularly relates to a kind of gapless arrestyer.
Background technology
The prevailing overvoltage protection device of China, is metal oxide arrester at present.Metal oxygen
When compound spark gap uses, by spark gap and by protection equipment earth.I.e. spark gap high voltage end
In parallel with by protection equipment, spark gap low-pressure end ground connection.When so power system having high voltage, keep away
Overvoltage energy is released into ground by thunder device, can effectively protect the safety of power system.Metal-oxide
Spark gap is all made up of zinc oxide nonlinear resistance slice serial or parallel connection.Znr
Sheet is the core parts of spark gap.The basic application principle of spark gap, it is simply that by the specified electricity of spark gap
Pressure design is near the reference voltage of zinc oxide resistance sheet, and under rated voltage effect, spark gap flows through
Electric current is milliampere level, and the electric current flow through under continuous running voltage is microampere order, sets with other electrical equipment
Standby leakage current is the same order of magnitude.Namely under normal working voltage, zinc oxide resistance sheet is height
Resistance, can run with long-term safety.Under big electric current overvoltage effect, as switching impulse overvoltage,
Lightning impulse overvoltage, zinc oxide resistance sheet shows as low resistance, limits the residual electricity at spark gap two ends
Pressure value, so that the overvoltage suffered by electric equipment is limited in the range of permission.Existing metal oxygen
Compound spark gap, no matter external insulation is porcelain overcoat or composite sheath, its structure be all by resistor disc string or
The core body composed in parallel, loads in porcelain overcoat or composite sheath, then by porcelain overcoat or composite sheath two
End seals.It seals structure many employings fluid sealant or rubber ring compression seal.Such sealing structure is past
The problem of moisture invasion in air in the long-play cannot solve spark gap.Power system is with keeping away
Thunder device cause of accident is because spark gap poor sealing more.

Described a kind of gapless arrestyer, including core body 7, described core body 7 is arranged in screen layer 2,
Being characterized in that described screen layer 2 pours molding outside core body 7, described core body 7 is multiple zinc oxide
Resistor disc is connected, and is provided with insulating barrier 3, at described core body 7 between described core body 7 and screen layer 2
Two ends are respectively arranged with electrode 8, bottom electrode 4, and described upper electrode 8 is provided with electrical terminals 9,
Stud 6, described electrical terminals 9, stud 6 and upper electrode 8, bottom electrode 4 it is provided with on bottom electrode 4
Between be threaded connection respectively.
It is provided with nut 5 on described stud 6.Described screen layer 2 is outside is provided with mounting flange 1.With
Existing technology is compared, and the beneficial effects of the utility model are, this utility model provides one continuously
Gap spark gap, application of the present utility model is respond well, has the most lightning-arrest effect, fully ensures
The safety of electrical equipment.
The foregoing is only preferred embodiment of the present utility model, not new in order to limit this practicality
Type, all any amendment, equivalent and improvement made within spirit of the present utility model and principle
Deng, within should be included in protection domain of the present utility model.
