Abstract
The utility model discloses a novel 10 kV switching type lightning arrester disassembling and assembling tool. A hole site is arranged at the non-open end of a U-shaped fork head, an arc site is arranged below the hole site, vertical convex columns arranged at the hole site and at the end of an insulation rod are mutually inserted, and horizontal convex columns arranged at the art site and at the end of the insulation rod are buckled with each other. By means of the structure, and electric operators can disassemble and assemble a lightning arrester very conveniently in work, thereby saving working time, and further guaranteeing safety of workers and devices. The novel 10 kV switching type lightning arrester disassembling and assembling tool is simple in structure, low in production cost and strong in practical applicability.
Description
Technical field
The utility model belongs to 10kV switching type lightning arrester dismantling device.
Background technology
Lightning arrester is that the transforming plant protecting electric equipment exempts from the equipment that lightning surge attacks.When the lightning surge of transformer station is imported on road along the line above the protection of arrester level into; Lightning arrester at first discharges; And, utilize earthing device to make the lightning voltage amplitude limitation below horizontal by protection equipment lightning impulse with the introducing the earth of lightning current through good conductor safety, electric equipment is protected.According to " power equipment preventive trial rules " regulation, must carry out preventive trial before power plant, the annual thunderstorm season of electric substation's zinc oxide arrester.10kV is non-, and the test of switching type zinc oxide arrester must have a power failure, and the test of switching type zinc oxide arrester need not have a power failure and can carry out.For reducing interruption duration, better service is in the client, and what the 10kV of transformer station outlet lightning arrester adopted now mainly is the switching type zinc oxide arrester.But in real work; Because 10kV outlet switching type zinc oxide arrester is installed on the outlet bar, about 5 meters even higher apart from ground, about the about 2KG of its deadweight; Dismounting is all not too easy; Sometimes in the disassembly process even the lightning arrester eminence occurs and fall, the person is damaged, or cause lightning arrester body or annex to damage.Trace it to its cause, the conventional instrument of dismounting lightning arrester generally adopts insulating bar at present, utilizes the outstanding strong point on insulating bar top to carry out dismounting, and the suspension member of lightning arrester can only hang on the outstanding strong point in insulating bar top.Higher apart from ground because of the switching type lightning arrester, the dismantling device arm of force of use is longer, occurs easily during dismounting being difficult to take off, bad installation, also can cause lightning arrester to fall damage sometimes.For addressing this problem, we have designed novel 10kV switching type lightning arrester dismantling device.
The utility model content
The utility model provides a kind of new tool in order to overcome the problem of switching type lightning arrester dismounting inconvenience, and is not only easy to use; And it is simple in structure; Be easy to make, invest minimum, thereby guarantee the member of shift personal safety; Shorten the operating time, guaranteed the novel 10kV switching type lightning arrester dismantling device that lightning arrester can not damage because of high falling.
The utility model is to realize through following technical scheme:
Novel 10kV switching type lightning arrester dismantling device, the non-openend of said U-shaped jaw is provided with the position, hole, is provided with the arc position below the position, hole.
The vertical projection that described Kong Weiyu insulating bar end is provided with is planted mutually.
The horizontal projection that described arc position and insulating bar end are provided with is interlocked.
The horizontal projection that arc position of said the utility model and insulating bar end are provided with is interlocked, play the fixedly effect of U-shaped jaw, has avoided U-shaped jaw in use often to occur rotating effectively and the phenomenon that can't use.
The utility model compared with prior art has following advantage:
Because the utility model adopts said structure, electrician operating personnel's dismounting lightning arrester when work is very convenient simple, has saved the operating time, has also guaranteed the safety of staff and equipment, and it is simple in structure, and low production cost is practical.
Description of drawings
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is the utility model U-shaped jaw and insulating bar syndeton sketch map;
Accompanying drawing 3 uses reference view for the utility model.
Among the figure 101, the U-shaped jaw, 36, the position, hole, 69, the arc position, 166, vertical projection, 108, horizontal projection, 98, insulating bar, 50, lightning arrester, 67, the lightning arrester groove.
Embodiment
To combine Figure of description to come the utility model is further described below:
Shown in accompanying drawing 1, accompanying drawing 2, accompanying drawing 3, novel 10kV switching type lightning arrester dismantling device, said U-shaped jaw 101 non-openends are provided with position, hole 36, are provided with arc position 69 below the position, hole.
The vertical projection 166 that described Kong Weiyu insulating bar end is provided with is planted mutually.
The horizontal projection 108 that described arc position and insulating bar end are provided with is interlocked.
The general workflow of the utility model will be described below:
When needs use the utility model; Plant with vertical projection 166 and horizontal projection 108 that insulating bar 98 ends are provided with, mutually shown in accompanying drawing 2 in the position, hole 36 and the arc position 69 that at first the non-openend of U-shaped jaw 101 are provided with; Then U-shaped jaw 101 is aimed at lightning arrester 50 groove 67 insertions on one's body; Shown in accompanying drawing 3, at this moment, the user can dismantle or install the lightning arrester that needs replacing easily.
