It should be noted that the herein presented noun of locality " upper and lower " direction refers to the upper and lower direction in Fig. 1.Herein
The noun of locality of middle appearance is set up on the basis of the usage of those skilled in the art and Figure of description, they
Appearance should not influence the protection scope of the utility model.
In order to make those skilled in the art more fully understand the utility model, with reference to the accompanying drawing and specifically
The utility model is described in further detail for embodiment.
Referring to FIG. 1, Fig. 1 is the structural representation of the support frame provided by the utility model for high voltage load switch
Figure.
The utility model provides a kind of support frame for high voltage load switch, including being set in outside contact tube 1
Pipe sleeve, the upper support frame for being installed on pipe sleeve upper end, and it is installed on the lower bracing frame of pipe sleeve lower end, pipe sleeve, upper support frame
Pipe sleeve ontology 2 is constituted with lower bracing frame, which is an integral structure, is made of high-temperature insulation material, can prevent
It is heated and deforms, aging, improve the service life of pipe sleeve ontology 2.During installation, pipe sleeve ontology 2 is set in contact tube 1
Outside surrounds contact tube 1 entirely, and so, pipe sleeve ontology 2 can completely cut off contact tube 1 with external environment completely, from
And contact tube 1 and extraneous insulation performance are increased, increase the creepage distance of upper and lower fuse, the electricity of high voltage load switch
Thus gas performance also gets a promotion.
Since contact tube 1 is both moving contact and cylinder, it driving connecting lever 4 driving force effect under, quickly into
Row linear motion, thus executes combined floodgate and sub-switching operation.Due to being equipped with piston inside contact tube 1, when on-load switch closes a floodgate
When, piston is opened, air is full of inside contact tube 1, when on-load switch separating brake, and piston motion, inside compression conductive copper pipe 1
Air, high-speed flow sprays from the resistance to electric arc plastic spout on top, electric arc blown out, therefore, to realize the reliable of separating brake
Property, contact tube 1 should have faster speed when moving, while contact tube 1 quickly moves, necessarily increase and lead to support
The impact forces of each support member of torch pipe 1, therefore, each supporting element need support strength with higher.Compared to existing
There is split type structure in technology, this has the support frame of integral structure, avoids the dispersion of support force, realizes to conductive copper
The entirety of pipe 1 concentrates support, and intensity is higher, bearing capacity is bigger, structural stability is more preferable, so that the movement of contact tube 1
It is more steady.
In this application, the pipe sleeve ontology 2 made of high-temperature insulation material, during installation, without having to worry about pipe sleeve ontology 2
The performance of earthing switch is in contact and influenced with earthing switch, therefore, pipe sleeve ontology 2 is not necessarily to avoid earthing switch,
In size design, without the size design of pipe sleeve ontology 2 is too long, and metal pipe sleeve in the prior art, just because of adopting
It is made of metal material, just makes the longer dimension of metal pipe sleeve, so that the overall dimensions of support frame are excessive.Therefore, originally
In application, pipe sleeve ontology 2 is made using high-temperature insulation material, the external form ruler for saving installation space, shortening pipe sleeve ontology 2
It is very little, realize the lightweight and miniaturization of high voltage load switch support frame.During installation, it is disposably installed with contact tube 1, peace
Dress process more saves time power.
From the foregoing, it can be seen that pipe sleeve ontology 2 is made of high-temperature insulation material, and it is an integral structure, improves pipe sleeve
The high temperature resistant of ontology 2, electrical insulation capability, and the mechanical properties such as support strength and stability for improving pipe sleeve ontology 2 are realized
The miniaturization and lightweight of support frame.
Above-mentioned pipe sleeve ontology 2, is preferably made of SMC high-temperature insulation material.SMC is Sheet molding compound
That is the abbreviation of sheet molding compound, due to SMC material have long service life, it is light, be integrally formed, product design is without engagement
The advantages that stitching, being produced on a large scale can make the mechanical property with higher of pipe sleeve ontology 2 as the making material of pipe sleeve ontology 2
Energy.
In order to improve the intensity of pipe sleeve ontology 2, multiple stiffening plates 3 can be set on pipe sleeve ontology 2.Stiffening plate 3 plays
Effect identical with reinforcing rib, constitutes stable triangular structure between stiffening plate 3 and pipe sleeve ontology 2, reinforced with this to improve
Bonding strength between plate 3 and pipe sleeve ontology 2 prevents pipe sleeve ontology 2 from deforming or fractureing due to by external force.
It is an integral structure between multiple stiffening plates 3 and pipe sleeve ontology 2, to facilitate production to process.Certainly, multiple stiffening plates
Between 3 and pipe sleeve ontology 2, it can also be detachably connected by bolt.
In order to increase creepage distance, full skirt 5 can be installed on pipe sleeve ontology 2, full skirt 5 is a circle along pipe sleeve ontology 2
The circle being circumferentially arranged has the protrusion of rounded structure, and full skirt 5 can increase creepage distance, to improve the exhausted of pipe sleeve ontology 2
Edge performance.The quantity of full skirt 5 can be to be multiple, and multiple full skirts 5 climb electricity along the axial direction distribution of pipe sleeve ontology 2 to further increase
Distance, and further improve the insulation performance of pipe sleeve ontology 2.
The utility model also provides a kind of high voltage load switch, including the above-mentioned support frame for high voltage load switch and
Cable outlet terminal, due to above-mentioned support frame so that the heat resistance of the high voltage load switch, electrical insulating property and intensity and
Bearing capacity gets a promotion.
Due in the prior art, being connected between fuse and cable outlet terminal by brass bolt, brass bolt is brass material
Material is made, and the contact resistance at screw thread is excessive, poor contact when easily on-load switch being caused to run and generate heat serious, or even burn
Subjacent cable is ruined, thus, there are great security risks.For the generation for avoiding safety accident, the utility model is using red copper mother
Row overlapped mode realizes the connection between fuse and cable outlet terminal, reduces the contact resistance of major loop as a result, makes
It is more safe and reliable to obtain on-load switch operation.It is connected by red copper busbar, increases the bonding strength of earthing switch, improve and connect
Ground switch electric property, and avoid because cable connection traction caused by major loop misplace the problem of.
In order to further increase the electric conductivity of on-load switch, the loop resistance of on-load switch is reduced, it can be in red copper mother
The electroplate of row, silver-plated red copper busbar, can make the contact resistance of major loop further decrease, to help to reduce
The generation of fever phenomenon when on-load switch is run.
The support frame to high voltage load switch provided by the utility model and its for high voltage load switch carries out above
It is discussed in detail.Specific case used herein is expounded the principles of the present invention and embodiment, the above reality
The explanation for applying example is merely used to help understand the method and its core concept of the utility model.It should be pointed out that being led for this technology
For the those of ordinary skill in domain, without departing from the principle of this utility model, if can also be carried out to the utility model
Dry improvement and modification, modifications and modifications also fall within the protection scope of the claims of the utility model.
