Utility model content
The technical problem to be solved by the present invention is to provide a kind of composite sheath power station types with high bending resistance energy to keep away
Thunder device.
To solve the above problems, the utility model adopts the following technical solution:
A kind of composite sheath power station type arrester, includes lower flange and lower part is crimped on epoxy insulation in lower flange
Cylinder, and with the inner tube wall of epoxy insulation cylinder lower part using the lower electrode being threadedly coupled, and be installed between lower electrode and lower flange
Sealing ring, and be crimped on the upper end cover on epoxy insulation cylinder top, and be arranged in it is in epoxy insulation cylinder, abutted against with upper end cover
Upper support tube.
Preferably, the epoxy insulation cylinder is provided with resistor disc, gasket, cushion cover, spring, conductive strips and spring base, institute
Resistor disc is stated to be equipped with a piece of above and be in be stacked.
It is arranged preferably, the resistor disc, gasket, cushion cover, spring, conductive strips and spring base stack gradually in lower electrode
Top, the spring base is connected to the lower section of support tube.
Preferably, vulcanization has a silicon rubber umbrella skirt on the outer tube wall of the epoxy insulation cylinder, the silicon rubber umbrella skirt it is upper
Portion is threadedly coupled with upper end cover, lower part is threadedly coupled with lower flange.
Preferably, being sealed connection between the upper end cover and epoxy insulation cylinder.
The utility model has the following beneficial effects: first, lower flange is used with epoxy insulation cylinder crimps connection, bending resistance is enhanced
Intensity；It the second, is to play outward flange crimping supporting role to reinforce insulating cylinder root bending strength again using lower electrode is lengthened；
Third, lower electrode and flange contact facings increase sealing ring, effective solution sealing problem；4th, upper end is added using end cap
Support barrel structure enhances bending strength.

Specific embodiment
Specific embodiment of the present utility model is described in further detail below in conjunction with attached drawing, so that the utility model technology
Scheme is more readily understood and grasps.
Refering to fig. 1 shown in -7, a kind of composite sheath power station type arrester.Include: epoxy insulation cylinder (1), lower flange (2),
Lower electrode (3), sealing ring (4), silicon rubber umbrella skirt (5), resistor disc (6), gasket (7), cushion cover (8), spring (9) conductive strips
(10), spring base (11), upper support tube (12), upper end cover (13).
Wherein, the arrester epoxy insulation cylinder (1) is connected, lower electrode on lower flange (2) using compression bonding method
(3) with epoxy insulation cylinder (1) using being threadedly coupled, which is internal screw thread (14), is added between lower electrode (3) and lower flange (2)
Dress sealing ring (4) is sealed.It is led equipped with resistor disc (6), gasket (7), cushion cover (8), spring (9) epoxy insulation cylinder (1) is inner
Electricity band (10), spring base (11), upper support tube (12), epoxy insulation cylinder (1) top is screwed in upper end cover (13) to be compressed and seals,
Junction uses external screw thread (15)；Lower flange (2) using connection is crimped, avoids threading from making ring with epoxy insulation cylinder (1)
Oxygen insulating cylinder (1) bending strength reduces, and inside increases the bending strength of insulating cylinder using lower electrode (3) are lengthened.Arrester top
Using upper end cover (13) and upper support tube (12) structure, the bending strength of whole arrester is improved.
It should guarantee reliability service under the collective effect of following mechanical loads by design standard requirement arrester:
A) the maximum horizontal pulling force F1 that arrester top is born:
35kV, 66kV system and neutral point arrester, F1=294N；
10kV system arrester, F1=490N；
220kV system arrester, F1=980N；
B) the wind pressure F2 on arrester is acted on, should be calculated as follows:
By taking the type arrester of the power station 110kV as an example: structure height 1196mm, gamp diameter 195mm are calculated: F2=(V02/
16) × α × S × 9.8=138 N
Arrester bears total external force: F=2.5(F1+1/2F2)
The N of F1=490N, F2=138
F=2.5(F1+1/2F2)=1397.5 N
A kind of practical endurance F >=4000N of composite sheath power station type arrester provided by the utility model.
The utility model has the following beneficial effects: first, lower flange is used with epoxy insulation cylinder crimps connection, bending resistance is enhanced
Intensity；It the second, is to play outward flange crimping supporting role to reinforce insulating cylinder root bending strength again using lower electrode is lengthened；
Third, lower electrode and flange contact facings increase sealing ring, effective solution sealing problem；4th, upper end is added using end cap
Support barrel structure enhances bending strength.
Above description is only a specific implementation of the present invention, but the protection scope of the utility model is not limited to
In this, any change or replacement expected without creative work be should be covered within the scope of the utility model.
