Abstract
The invention discloses a detachable arrester, which mainly comprises an arrester and an insulated mounting post. The arrester is electrically connected with the upper end of the insulated mounting post through a moving contact and is electrically connected with the lower end of the insulated mounting post through a stationary contact, one end of the stationary contact is hinged with the arrester, the other end of the stationary contact is a Z-shaped connecting end, the lower end of the insulated mounting post is provided with a screw hole, the Z-shaped connecting end of the stationary contact is connected with the screw hole at the lower end of the insulated mounting post through a bolt in a screwing way, and the front end of the Z-shaped connecting end is provided with a grounding plate; and the lower end of the arrester is provided with a detachable device. The detachable arrester is installed on a falling type mechanism of a falling type fuse, the arrester can be conveniently detected, maintained and replaced via an insulated pulling ring with no needs for power disconnection, the smoothness of the line can be ensured, the working intensity and time of power maintenance staff can be reduced greatly, and the detachable arrester is particularly suitable for places where power cannot be cut off freely, such as places of post and telecommunications, airports, stations, hospitals and downtown business districts.
Description
Technical field
The present invention relates to a kind of electric prospection equipment, relate in particular to a kind of detachable lightning arrester.
Background technology
The effect of lightning arrester is to be used for protecting the electrical equipment that various electric equipments are avoided lightning overvoltage, switching overvoltage in the electric power system, Frequency Transient Overvoltage is impacted and damage; Can discharge thunder and lightning or hold concurrently and to discharge power system operation overvoltage energy; The protection electrical equipment is avoided instantaneous overvoltage harm; Can block afterflow again, the unlikely electrical installation that causes the system earth short circuit.Lightning arrester is connected between live wire and the ground usually, with parallelly connected by protection equipment.When overvoltage value reached specified action voltage, lightning arrester moved immediately, flow through electric charge, and the over-voltage amplitude is protected apparatus insulated; After magnitude of voltage was normal, lightning arrester restored to the original state rapidly again, to guarantee system's normal power supply.
The type of lightning arrester mainly contains protection gap, valve-type arrester and zinc oxide arrester.The protection gap is mainly used in the restriction atmospheric over-voltage, generally is used for distribution system, circuit and inlet wire of substation segment protect.Valve-type arrester and zinc oxide arrester are used for the protection in electric substation and power plant, are mainly used in the restriction atmospheric over-voltage at 500KV and following system, in extra high voltage system, also will be used for limiting internal overvoltage or do the backup protection of internal overvoltage.
When lightning arrester breaks down or damage, need releasing mechanism lightning arrester and ground path are broken off, prevent the further expansion of accident, and be easy to the attendant and in time find to safeguard.
Summary of the invention
In view of this, the invention provides a kind of detachable lightning arrester, when lightning arrester breaks down or damage, lightning arrester and ground path are broken off, guarantee circuit safety.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
A kind of detachable lightning arrester; 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 hinged on the lightning arrester, and the other end is " Z " font link, and insulating mounting pillar lower end is provided with screw; " Z " font link of fixed contact spins through the screw of bolt and insulating mounting pillar lower end, and " Z " font 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 alloy fuse piece that is arranged between disconnector and the fixed contact.
Good effect of the present invention is:
Because of the present invention is installed in the drop type mechanism of fuse switch after the distribution type zinc oxide arrester repacking dexterously; 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, place that is particularly suitable for having a power failure such as post and telecommunications, station, airport, hospital, bustling business district use.
Disconnector of the present invention 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; Alloy 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 present invention is simple in structure, and production cost is low, and is good in economic efficiency.
