Description
Technical field
The utility model relates to a kind of arresters, more particularly to a kind of conveniently detachable arrester.
Background technique
Power industry will carry out the checking experiment and preservation & testing of arrester every year, dismantle test work in traditional lightning protection device
In work, the arrester in transformer rack is removed firstly the need of power failure by maintenance teams and groups, and then restorer is powered.General one
A change platform process is most conservative to need 1 hour, and there are also the single pole transformer that part is installed under main line, arrester is installed in single pole
Transformer control fuse upside, to remove arrester whole 10 KV line must also be carried out have a power failure could carry out take shelter from the thunder
The dismounting testing operation of device, at least at 3 hours or more, power failure operation is brought 10 KV line power off time of each to user
Inconvenience.
Summary of the invention
The purpose of the utility model is to provide a kind of detachable arresters, to solve traditional lightning protection device in checking experiment and dimension
The technical deficiency of power failure operation is needed when shield detection.
In order to solve the above technical deficiency, the utility model adopts the following technical solution:
A kind of detachable arrester, including insulator and lightning arrester body fastened to each other, the upper end of the insulator and
Lower end is respectively fixed with top static contact and lower part static contact, and the top static contact includes the top static contact cover being fixedly linked
Plate, elastomeric element and duckbilled copper sheet, the lower part static contact include grounding body and the copper hook being fixedly linked with the grounding body；
The lightning arrester body upper end is provided with the top moving contact with the cooperation of the top static contact of insulator, the top
Moving contact is fixed with operation ring, and the lightning arrester body lower end is provided with dynamic with the lower part of the lower part static contact of insulator cooperation
Contact, the lower part moving contact are fixed with lower operation ring.
Preferably, the elastomeric element is spring.
The detachable arrester of the utility model is due to using technical solution as above, so that staff need to only use absolutely
Edge bar can be carried out the disassembly of arrester, installation operation, not only can guarantee that electricity consumer does not have a power failure, and also reduces artificial, vehicle fees
With investment, while decreasing the security risk in upkeep operation.
Detailed description of the invention
Fig. 1 is the installation condition schematic diagram of detachable arrester described in the utility model embodiment 1；
Fig. 2 is the top static contact schematic diagram of internal structure of detachable arrester described in the utility model embodiment 1；
Fig. 3 is the disassembly status schematic diagram of detachable arrester described in the utility model embodiment 1.
Specific embodiment
With reference to the accompanying drawing and specific embodiment is described further the utility model, but the utility model and not only limits
In following implementation.
Embodiment 1
Also referring to Fig. 1 and Fig. 2, a kind of detachable arrester, including insulator 1 fastened to each other and lightning arrester body
2, the top and bottom of the insulator are respectively fixed with top static contact 11 and lower part static contact 12, the top static contact 11
Including top static contact cover board 111, spring 112 and the duckbilled copper sheet 113 being fixedly linked, the spring is fixed on top static contact
Between cover board and duckbilled copper sheet, the lower part static contact 12 includes grounding body 121 and the copper being fixedly linked with the grounding body
Hook 122；The lightning arrester body upper end is provided with the top moving contact 21 with the cooperation of the top static contact of insulator, for convenience
Using insulating bar operation, be fixed with upper operation ring 211 on the top moving contact, the lightning arrester body lower end be provided with
The lower part moving contact 22 of the lower part static contact cooperation of insulator, is fixed with lower operation ring 221 on the lower part moving contact.
When zinc oxide surge arresters, insulating bar is protruded into lower operation ring 221, arrester is linked into the copper hook of lower part static contact
It in 122, hangs on arrester on lower part static contact 12, then insulating bar is protruded into upper operation ring 211, push arrester to duck
The groove of mouth copper sheet 113 moves, and slides into the top moving contact of arrester in the groove of duckbilled copper sheet and reaches fixed mesh
's.The top moving contact of duckbilled copper sheet and arrester closely connects under the active force of spring 112.
When dismantling arrester, insulating bar is protruded into upper operation ring 211, pulls arrester to move out, makes arrester
The groove of top moving contact 21 and duckbilled copper sheet 113 is detached from, as shown in figure 3, under the effect of gravity, arrester is under insulator
The junction of portion's static contact 12 and the lower part moving contact 22 of arrester is that axis rotation naturally droops, then insulating bar is protruded into lower operation
In ring 221, the lower part moving contact 22 of arrester is taken out from copper hook 122, to realize the disassembly operation of arrester.
Detachable arrester described in the utility model, so that staff need to only use insulating bar to can be carried out taking shelter from the thunder
The disassembly and installation operation of device not only can guarantee that electricity consumer does not have a power failure, and also reduce artificial, vehicle expense investment, while also reducing
Security risk in upkeep operation improves power supply reliability and continuity, promotes the electricity consumption experience of user energetically.
