Abstract
The invention discloses a metallic oxide lightning arrester with a built-in insulation base. The metallic oxide lighting arrester with the built-in insulation base is characterized by comprising an aluminum cushion block, a screw, an insulation base, an aluminum electrode, a counter and base bolt, wherein the aluminum cushion block and the insulation base are arranged in the tail part of a core unit of the lightning arrester and clamped between a resistor disc and the aluminum electrode, a screw hole is formed in the aluminum block, one end of the screw is screwed into the aluminum, and the other end of the screw is arranged outside a silicone rubber case of the lightning arrester; the screw is connected with one end of the counter, and the other end of the counter is connected to the base bolt of the lightning arrester. According to the lightning arrester with the structure, the short circuit phenomenon of the counter in the rainy weather can be effectively prevented, and accordingly the effective on-line detection of the discharge counter on the lightning arrester can be guaranteed.
Description
Technical field
The present invention relates to composite greatcoat type metal-oxide lighting arrester, be specifically related to a kind of metal oxide arrester of built-in insulation base.
Background technology
Lightning arrester is the visual plant of the normal operation of protection high voltage electric equipment; therefore in the power system operation process; discharge scenario to lightning arrester adopts discharge counter to carry out effectively online the detection usually; in order to the fine status of lightning arrester and maintenance, life cycle are carried out monitoring and metering; in time change or maintenance; guarantee thus the reliability service of electric power system, avoid the generation of equipment breakdown.Discharge counter generally is installed on the lightning arrester base, and base is comprised of two block plates, the middle spacer insulator piece of placing, and discharge counter could be connected to two block plates by wire and finish and be installed in series.Under the rainwater weather condition, the conducting phenomenon can appear in lightning arrester base insulation position, thereby the counter short circuit can't detect metering to lightning arrester.
Summary of the invention
For solving the defects of prior art existence, the object of the present invention is to provide a kind of metal oxide arrester of built-in insulation base.
For addressing the above problem, the technical scheme that the present invention takes is that the metal oxide arrester of described built-in insulation base comprises: aluminium cushion block, screw, insulator foot, aluminium electrode, counter, bolt of lower base, be provided with aluminium cushion block and insulator foot in lightning arrester core group afterbody inside, aluminium cushion block and insulator foot are clipped in the middle of resistor disc and the aluminium electrode, on the aluminium cushion block screw hole is arranged, one on screw is screwed into aluminium cushion block, one and is exposed at lightning arrester silica gel sheath outside; One end of described screw linkage counter, the counter other end is connected on the lightning arrester base bolt.
Inner aluminium cushion block and the insulator foot of increasing of lightning arrester core group afterbody, aluminium cushion block and insulator foot are clipped in the middle of resistor disc and the aluminium electrode, on the aluminium cushion block screw hole are arranged, and one on screw is screwed into one of aluminium cushion block and is exposed at lightning arrester silica gel sheath outside.Lightning arrester integral body has not conducting of collets because of inside, an end of screw linkage counter, and the counter other end is connected on the lightning arrester base bolt.
Because adopt technique scheme, the invention has the beneficial effects as follows: this structure lightning arrester is effectively avoided counter short circuit phenomenon under the rainwater weather condition, guaranteed effectively online detect of discharge counter to lightning arrester.
