Description
Technical field
The invention belongs to the deodorization technique field that sterilizes, and in particular to a kind of metal oxide arrester.
Background technology
Transmission line of electricity realizes connection of the wire with shaft tower by insulator, often because of the circuit that is struck by lightning under this line construction
Insulator is caused to bear very high lightning surge, so as to cause insulator flashover damage occur.The electricity that was struck by lightning is met with circuit
During pressure, insulator will bear lightning voltage and flashover damage occurs, when lightning voltage exceedes certain amplitude, except causing line tripping
Outside, insulator damage is also resulted in so as to lose insulating properties.In order to ensure that insulator remains to normal work after thunderbolt, mainly
The method of use is insulator lightning arrester connected in parallel, and arrester acts first when being struck by lightning, and ensures that insulator is excessively electric from thunder and lightning
Caused by pressure flashover damage, but this method in real work exist further complicate line facility configuration, increase steel tower,
The shortcomings of load of cement pole, simultaneously because the position of overhead line structures cross-arm and limited length, cause arrester in practice of construction
Middle installation inconvenience, more it can cause to have more difficult situation during line live-line work because cross arm of tower carry equipment is excessive.
The content of the invention
It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, there is provided a kind of metal oxide arrester.
A kind of metal oxide arrester, including：Composite sheath, resistor disc, upper grading ring, lower uniform pressure ring, plug；It is special
Sign is：The composite sheath is metal oxide material, and the both ends of composite sheath are connected by flange with gland, and gland is convex
Platform is pushed against with pressing plate boss, and the pillared resistor disc of closed assembly is provided between two groups of pressing plates, filling is filled with the inner chamber of resistor disc
Agent, plug both ends are threadedly coupled with insulated terminal, and sealing-plug is pressed in the centre bore of gland by insulated terminal, gland and pressure
Spring is provided with toroidal cavity between plate, upper grading ring is fixed on the middle part of composite sheath by support, and lower uniform pressure ring passes through
Support is fixed on the bottom of composite sheath.
Preferably, it is raised to be provided with umbrella for the outside of the composite sheath.
Preferably, it is provided with elastomeric pad between the gland boss and pressing plate boss.
Compared with prior art, beneficial effects of the present invention：
The present invention integrates arrester and insulator function, overcomes what existing arrester and insulator must be installed in parallel
Limitation, on the premise of line construction complexity is not increased, realize the dual-use function of support wire and thunder discharge water conservancy diversion；
The insulator of former circuit can be directly substituted in actual use, this equipment is not being changed line construction
Situation is issued to insulator and the function of arrester is unified within one device, and can be advantageously applied to existing line；
Load stretching force part of the present invention is mainly the plug through arrester, and composite sheath and resistor disc then undertake
The effect of lightning current discharge path, is not subject to the pulling force of wire, less influences the stress of plug in itself.
