Abstract
The utility model discloses a non-power failure changeable lightning arrester which is mainly provided with a lightning arrester and an insulated mounting strut, wherein the lightning arrester is electrically connected with the upper end of the insulated mounting strut through a movable contact terminal, the lightning arrester is electrically connected with the lower end of the insulated mounting strut through a static contact terminal, one end of the static contact terminal is connected on the lightning arrester, the other end of the static contact terminal is a broken line-shaped connecting end, a screw hole is arranged on the lower end of the insulated mounting strut, the broken line-shaped connecting end of the static contact terminal is helically connected with the screw hole on the lower end of the insulated mounting strut through a bolt, and a grounding plate is further arranged on the front end of the broken line-shaped connecting end; and a releaser is further arranged on the lower end of the lightning arrester. The non-power failure changeable lightning arrester disclosed by the utility model is installed on a dropping structure of a dropping fuse to conveniently detect, maintain and change the lightning arrester through an insulating pull ring on a non-power failure condition, thereby guaranteeing the circuit smoothness and greatly reducing the working intensity and time of the electric power maintainers.
Description
[technical field]
The utility model relates to a kind of electric prospection equipment, relates in particular to a kind of changeable type lightning arrester that do not have a power failure.
[background technology]
The tradition lightning arrester breaks down and be difficult for to find that the line upkeep workload is big, change with debugging lightning arrester process in must ascend operation, for operating personnel certain danger is arranged, be prone to cause personal injury accidents.And after traditional lightning arrester receives extraneous overvoltage impact failure, be prone to cause whole piece line-to-ground even short circuit tripping operation, cause whole piece line-to-ground even power failure.The maintenance of tradition lightning arrester needs the outage operation with replacing, and inefficiency has a strong impact on job schedule, in changing the lightning arrester process, needs the power failure operation, and is consuming time serious, has a strong impact on normal electricity consumption.
[summary of the invention]
The technical problem that the utility model will solve has provided a kind of changeable type lightning arrester that do not have a power failure, and when lightning arrester breaks down or damage, lightning arrester and ground path is broken off, and guarantees circuit safety.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is a kind of changeable type lightning arrester that do not have a power failure; Mainly be provided with lightning arrester and insulating mounting pillar, lightning arrester is electrically connected through moving contact with insulating mounting pillar upper end, and lightning arrester is electrically connected through fixed contact with insulating mounting pillar lower end; Wherein, The first end of stationary contact is connected on the lightning arrester, and the other end is the polyline shaped link, and insulating mounting pillar lower end is provided with screw; The polyline shaped link of fixed contact spins through the screw of bolt and insulating mounting pillar lower end, and polyline shaped link front end also is provided with ground plate; The lightning arrester lower end also is provided with disconnector, and disconnector is provided with the disengaging assembly that fixed contact is separated with disconnector, also is provided with the high-pressure side binding post on the moving contact.
Described disconnector is the hot melten type disconnector, and the said disengaging assembly that fixed contact is separated with disconnector is the metal fuse piece that is arranged between disconnector and the fixed contact.
The beneficial effect of the utility model is; The utility model is installed in the drop type mechanism of fuse switch after distribution type zinc oxide arrester is reequiped; Reach under the situation of not cutting off the power supply, can detect, keep in repair and change, not only guarantee the unimpeded of circuit to lightning arrester easily but also reduce electric power maintenance personnel's working strength and time widely by the insulation draw ring.
The disconnector of the utility model can increase according to the zinc oxide arrester power current of changing in quality; The short circuit current in the inefficacy lightning arrester is flow through in utilization; Metal fuse piece in the disconnector is fused reach lightning arrester and hightail the insulating mounting pillar; Make the attendant in time find the fault lightning arrester, change and maintenance.
The preventive trial of the utility model lightning arrester or replacing operation are also very convenient, and prerun or replacing personnel draw back lightning arrester holder upper contact head fastener with link rod, and lightning arrester is fallen, and choose down lightning arrester with link rod and carry out prerun.
The use of this novel lightning arrester has solved lightning arrester prerun in the past or has changed the operation of must under power-off condition, ascending a height, the drawback that not only influences power supply reliability but also waste time and energy.
[description of drawings]
Below in conjunction with accompanying drawing and embodiment the utility model is done further detailed explanation.
