Description
Technical field
The present invention relates to grid equipment technical field, specially a kind of deterioration can show, can charged for replacement core arrester
And its repair method.
Background technology
Conventional arrester is to use that varistor valve first is made as core, then core is directly born against in silicon rubber
Or the manufacturing process in insulator, arrester electrode is exposed to the atmosphere, easy pollution flashover, and is unfavorable for the development side of insulating taiwan area
To, while also there are following inconvenience：
1) valve block damage occurs for lightning arrester core body, and detection difficulty is larger, it is difficult to be found, even if being detected, because not
It can do over again, cause to waste.
2) for product during normal operation, detection is inconvenient, and maintenance cost is very high.
3) a certain component of product goes wrong, it is necessary to which whole replacement of products can not repair, and cost is very high, while also unfavorable
In accident analysis.
4) arrester checks, the necessary power failure operation of replacement, influence normally to produce, live.
Invention content
The shortcomings that the purpose of the present invention is overcoming the above-mentioned prior art, provide a kind of deterioration can show, can charged for replacement core
Arrester, the top and the bottom electrode of arrester is insulation outlet, and bottom carries sealing cover, can prevent internal contamination, work as zinc oxide
The aging of valve block core to a certain extent, by thermal explosion disconnector washed open by sealing cover, and arrester and power grid, which disconnect, to be electrically connected, avoid because
Arrester internal breakdown causes singlephase earth fault, meanwhile, arrester sealing cover, which flicks, provides apparent deterioration prompting, facilitates line walking
Personnel have found trouble point in time, and lightning arrester core body is only needed to change under charged condition.
The present invention is achieved through the following technical solutions：

With the thread head of threaded hole cooperation, the mandrel component is connected by the threaded hole of top electrode block and the thread head of accommodating cavity bottom
It connects, mandrel component is made to be mounted in the accommodating cavity of arrester sealed insulation housing.
As the improvement of said program, the non-linear resistor column passes through Du by multiple zinc oxide varistor valves
The curing of Lipton layer is integrated.
As the improvement of said program, the end face of the end cover is equipped with holddown spring, at the end of holddown spring
Portion is equipped with compress gasket, when the end cover lid is closed outside arrester sealed insulation on set, the clamping pad on holddown spring
Piece is kept out on the thermal explosion disconnector.
As the improvement of said program, sealing ring is equipped between the end cover and arrester sealed insulation housing.
As the improvement of said program, it is in lid conjunction in the end cover or flicks state as fault identification mark
Note.
As the improvement of said program, described ground insulation annealed copper wire one end is connect with end cover, the other end and bar
Tower cross-arm connects；The state that flicks is in the end cover to mark as fault identification.
A kind of deterioration can show, can charged for replacement core arrester repair method, be as follows：
Step 1. is delivered to power grid setting position and carries out installation fixation after arrester is completed on ground；
Step 2. arrester works normally, and is needed replacing when the zinc oxide varistor valve of internal core rod component is aged to
Degree when, generate the increase of power frequency leakage current, act thermal explosion disconnector connect with mandrel component, promotion end cover is beaten
It opens, the mandrel component of aging is made electrically to be disconnected with circuit；
Whether step 3. track walker need to only open when patrolling circuit in the end cover of ground observation arrester
Judge the operating status of arrester, if end cover for lightning arrester flicks, arrester is in malfunction, otherwise, normal work；
Step 4. can directly utilize the plug of insulating bar charged for replacement arrester for failure arrester, maintenance personal
Then component covers end cover and repair can be completed.
The invention has the advantages that：
1. the upper and lower electrode of arrester is high with lead wire insulation degree, meet insulating taiwan area technological development direction.
2. can charged for replacement lightning arrester core body, save power off time and expense, it is detection, easy to maintain.
