Description
The technical field is as follows:
the invention relates to the field of research and development design of separable hanging type gapless arresters, in particular to a live-line operation full-insulation separable hanging type gapless arrester device.
Background art:
the traditional international HY5W type composite jacket metal oxide gapless lightning arrester is a lightning protection product with the largest application in the current line lightning protection, because the gapless lightning arrester bears system voltage for a long time in the system operation, the gapless lightning arrester has the risk of easy aging and damage and needs to be periodically overhauled and replaced, the main defect is that once the lightning arrester is damaged, the lightning arrester can only wait for power failure for replacement, lightning stroke and overvoltage damage once again can not continue to play a role in protection during the replacement, and the application of a bucket arm vehicle for electrified replacement can consume a large amount of manpower and material resources and is limited by terrain.
Another drop-out arrester disclosed in CN201320171068.7 is obtained by modifying a zinc oxide arrester and then installing the modified zinc oxide arrester on a drop-out mechanism of an original drop-out fuse, so that the arrester can be detected, maintained and replaced by means of an insulating operating rod under the condition of no power failure. The defect is that the falling mechanism has complex structure, high processing cost and troublesome assembly; the main electrical elements are exposed and easy to age, pollute and flash and short circuit, and the whole insulation design process is influenced; when the lightning arrester body is closed, the elastic sheet is compressed to store energy, so that fatigue failure is easy to occur, when the disconnector breaks down, a falling mechanism fails, and the lightning protection of a line is not set; the falling mechanism is also arranged on a line cross arm outdoors, the lightning arrester has short relative service life in an overhead line material and is easy to damage, and the current troublesome outstanding problems of inspection, maintenance and replacement are particularly the obvious problems of the power department, particularly the exposed part of the zinc oxide lightning arrester is made of silicon rubber, and the silicon rubber product is easy to age, crack and tear under natural environment and is easy to be torn by birds, so that the service life is reduced, the number of electrical connection points is large, namely, the number of electrical fault points is large, and the insulation and the attractiveness of the whole line are also influenced; although the damaged lightning arrester body can be detached to be replaced with electricity when damaged, the drop-out lightning arrester must be matched with the disconnector, cannot be used without being matched with the disconnector, and is low in integration level and heavy.
The other is a chamber arrester, which mainly moves the zinc oxide arrester body from the outdoor to the indoor, and reduces the influence of the natural environment on the arrester body; the lightning arrester can be detected, maintained and replaced by the aid of the insulating operating rod. Although the lightning arrester has the function of quickly replacing the lightning arrester body in live working, the lightning arrester does not have the function of quickly, simply and conveniently installing and disassembling the lightning arrester in live working; the porcelain outer sleeve is heavy and fragile, once the lightning arrester breaks down and bursts, the splashed metal oxide and the fragile porcelain outer sleeve easily damage other electrical equipment and passers-by, and the porcelain outer sleeve is installed at the high position of a line and is inconvenient to construct; the lightning arrester is characterized in that a sealing design is not arranged between the lightning arrester body and the cavity, the lightning arrester is influenced by the environment after long-time operation, the cavity is easy to enter water and gas for salting under the severe weather environment condition, and the fault is caused, particularly in the area with high salt mist concentration in the coastal area; because the sealing treatment is not carried out between the lightning arrester body and the cavity, the lightning arrester body needs to increase the insulation height and the creepage shed distance, so that the weight is increased, the lightning arrester is easy to drop due to the overweight dead weight, and the overall cost is overhigh; the lightning arrester is not provided with an electricity testing grounding device, the grounding wire is inconvenient to hang, the lightning arrester body is directly pulled out from the cavity, the arc discharge phenomenon is easy to cause, a lightning arrester cross arm needs to be specially installed for installing the lightning arrester, the line is not attractive, the cost is increased, and the actual sealed and closed full insulation cannot be realized due to the fact that the twisted buckle type insulating cover is easy to blow and drop; the intelligent power grid is difficult to be matched with and additionally provided with an intelligent detection device.
The invention content is as follows:
the invention aims to overcome the defects, and aims to research a lightning arrester device which can be used for quickly mounting or dismounting the whole lightning arrester in hot-line work only by virtue of an insulating operating rod, can also be used for quickly separating, overhauling, plugging and replacing a lightning arrester body in hot-line work, is provided with an electricity testing grounding rod to conveniently hang a ground wire and can be hung on an original iron cross arm of a circuit.
