Description
Technical field
The utility model belongs to arrester technical field, and in particular to a kind of Zinc-Oxide Arrester.
Background technology
Arrester is connected between cable and the earth, usually in parallel with by protection equipment.Arrester can be effectively protected
Equipment, once there is abnormal voltage, arrester will act, and play a protective role.When cable or equipment are working normally
When being run under voltage, arrester will not act, and be considered as open circuit for ground.Once there is high voltage, and jeopardizes and protected
When protecting apparatus insulated, arrester acts immediately, by high-voltage impact conduct current the earth, to limit voltage magnitude, protective wire
Cable and apparatus insulated.After having served as loss of voltage, arrester restores to the original state rapidly, and circuit is made to work normally.
Existing arrester is mostly gap discharge form, due to being equipped with discharging gap, often causes insulator pollution to electricity
The defects of pressure is distributed and the influence of discharge voltage, while there is also the dispersibilities of discharge voltage.
Utility model content
The purpose of the utility model is to overcome above-mentioned the deficiencies in the prior art, provide a kind of Zinc-Oxide Arrester.
A kind of Zinc-Oxide Arrester of technical solutions of the utility model, including outer insulator, zinc oxide valve plate, spring, the oxygen
Change zinc valve block to be superimposed upon in casing vertically, the zinc oxide valve plate and casing are encapsulated in outer insulator, the top of the outer insulator
It is respectively fixed with upper flange and lower flange with lower part, the upper flange is fixedly connected by bolt with capping, on the inside of the capping
Bottom be fixed with connecting plate, the bottom of the connecting plate is fixed with gland, the zinc oxide valve plate of the gland and top layer it
Between be equipped with spring, the top of the spring is fixed on the bottom of gland, and the bottom of described sleeve pipe is fixed on lower connecting plate.
Preferably, the lower connecting plate is connected with bottom plate, and the bottom plate is fixedly connected by bolt with lower flange.
Preferably, sealing ring is equipped between the connecting plate and upper flange.
Compared with prior art, the utility model has the beneficial effects that：
The utility model realizes the compression between zinc oxide valve plate by spring, to which the steady of arrester operation be effectively ensured
It is qualitative, have the advantages that good reliability, while the installation and removal of arrester entirety can be facilitated by spring compression；By setting
Sealing ring is set, can effectively ensure that the sealing of arrester entirety, while extending service life of equipment, ensures arrester operation
Reliability and safety.

The bottom of 1 inside of capping is fixed with connecting plate 3, and the bottom of the connecting plate 3 is fixed with gland 4, the gland 4 and top layer
Spring 6 is equipped between zinc oxide valve plate 7, the top of the spring 6 is fixed on the bottom of gland 4, and the bottom of described sleeve pipe 8 is fixed
On lower connecting plate 12, the lower connecting plate 12 is connected with bottom plate 11, and the bottom plate 11 is fixed by bolt and lower flange 10
Connection is equipped with sealing ring 5 between the connecting plate 3 and upper flange 2.
The operation principle of the utility model is：
When the utility model is used, mounted on the upper side for needing progress lighting protection, when meeting with lightning stroke, in thunder and lightning
Under overvoltage effect, the zinc oxide valve plate 7 being superimposed is breakdown, Low ESR is presented under 7 high voltage of zinc oxide valve plate, by thunder
Current drain enters ground；After lightning impulse, afterflow is interdicted, system is returned to normal operating condition.
Technical solutions of the utility model are exemplarily described utility model above in conjunction with attached drawing, it is clear that this practicality
Novel specific implementation is not subject to the restrictions described above, as long as using the methodology and technical solution progress of the utility model
Various unsubstantialities improve, or it is not improved the design of utility model and technical solution are directly applied into other occasions,
It both is within the protection scope of the present invention.
