Description
Technical field
This utility model relates to electrical equipment technical field, a kind of detachable Zinc-Oxide Arrester.
Background technology
Zinc-Oxide Arrester is the spark gap with good protection performance.Utilize the non-linear volt that zinc oxide is good
Peace characteristic, makes the electric current flowing through spark gap when normal working voltage minimum (microampere or milliampere level)；Serve as
During voltage effect, resistance drastically declines, the energy of overvoltage of releasing, and reaches the effect of protection.This keep away
The difference of thunder device and traditional spark gap is that it does not has discharging gap, utilizes the nonlinear characteristic of zinc oxide to rise
To earial drainage and the effect cut-off.Zinc-Oxide Arrester of the prior art is non-dismountable, function singleness, no
Maintainer is facilitated quickly to find trouble point.
Utility model content
The purpose of this utility model is to provide a kind of detachable Zinc-Oxide Arrester, to solve above-mentioned background
The problem proposed in technology.
For achieving the above object, the following technical scheme of this utility model offer: a kind of detachable zinc oxide
Spark gap, including base, the top, one end of described base is provided with locating groove, and in locating groove, clamping is propped up
Frame, the other end of described base connects thermal explosion disconnector, and the top of described support is connected by mariages to be had
Supports insulative, the upper end of described supports insulative connects cross-arm by mariages, under the front end of described cross-arm
Surface connect have stage clip, the lower end of stage clip contact with thermal explosion disconnector, the top of thermal explosion disconnector be provided with
The draw ring that cross-arm connects.
Preferably, the middle inside of described base is provided with the reinforcement that 2 to 3 stainless steel materials are made.
Preferably, the outside of described cross-arm is cased with de-icer boot.
Preferably, the bracket holes of square hole shape is left at the middle part of described cross-arm.
Compared with prior art, the beneficial effects of the utility model are: this detachable Zinc-Oxide Arrester
Can automatically fall during fault and form distinguishing mark, it is easy to find, in order to on-call maintenance is changed, and work
Stability good, it is easy to install, service life is long, greatly reduce electric power maintenance personnel working strength and
Time.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
In figure: 1 base, 11 locating grooves, 12 reinforcements, 2 supports, 3 thermal explosion disconnectors, 4 supports
Insulator, 5 cross-arms, 6 stage clips, 7 draw rings, 8 de-icer boots.
Detailed description of the invention
Below in conjunction with the accompanying drawing in this utility model embodiment, to the technology in this utility model embodiment
Scheme is clearly and completely described, it is clear that described embodiment is only this utility model one
Divide embodiment rather than whole embodiments.Based on the embodiment in this utility model, this area is common
The every other embodiment that technical staff is obtained under not making creative work premise, broadly falls into this
The scope of utility model protection.
Referring to Fig. 1, this utility model provides a kind of technical scheme: a kind of detachable Zinc-Oxide Arrester,
Including base 1, the middle inside of base 1 is provided with the reinforcement 12 that 2 to 3 stainless steel materials are made,
Ensure that the intensity of base 1, the top, one end of base 1 is provided with locating groove 11, in order to fixing holding props up
Support insulator 4 and spark gap concentric, prevents the situations such as the twisting dislocation, deciliter difficulty that cause during drawing,
Clamping support 2 in locating groove 11, the other end of base 1 connects has thermal explosion disconnector 3, at spark gap
When breaking down, utilize power frequency short circuit current by thermal explosion disconnector 3 action；Make thermal explosion disconnector 3 ground connection
End disengages automatically, and spark gap falls.Greatly strengthen attendant's visuality to trouble point, be provided with
Distinguishing mark is formed, it is easy to find, in order to on-call maintenance is changed, support 2 because can automatically fall during fault
Top by mariages connect have supports insulative 4, the upper end of supports insulative 4 to connect cross-arm by mariages
5, supports insulative about 4 all uses mariages to fix, and enhances the stability of supports insulative 4 greatly,
The front underside of cross-arm 5 connects has stage clip 6, the lower end of stage clip 6 to contact with thermal explosion disconnector 3, thermal explosion
The top of disconnector 3 is provided with the draw ring 7 connected with cross-arm 5, and the outside of cross-arm 5 is cased with de-icer boot 8, energy
Being prevented effectively from the ice and snow weight to cross-arm 5, the bracket holes of square hole shape is left at the middle part of cross-arm 5, can install
There is location anti-twisting, loosening cup square neck bolt, it is ensured that the stability of whole device work.
Embodiment the most of the present utility model, for the ordinary skill people of this area
For Yuan, it is possible to understand that can be real to these in the case of without departing from principle of the present utility model and spirit
Executing example to carry out multiple change, revise, replace and modification, scope of the present utility model is by claims
And equivalent limits.
