Abstract
The present invention relates to a kind of protective device for high pressure, ultra-high voltage cross-linking cable transition joint, this protective device comprises housing and obturator, and described housing is tubular, is divided into three sections, is respectively the left side section, interlude, the right section that connect successively; Described cable intermediate joint is located in housing, and described obturator is located between housing and cable intermediate joint.Compared with prior art, the present invention has the advantages such as compact conformation is small and exquisite, quality light, environmental protection.
Description
Technical field
The present invention relates to a kind of connector protection device, especially relate to a kind of protective device for high pressure, ultra-high voltage cross-linking cable transition joint.
Background technology
Cable joint punctures can discharge a large amount of energy with during explosion accident, works the mischief, even can cause the generation of second accident to other operation cable lines of periphery, facility or personnel.Current joint fire prevention, explosive-proof protector box product are mainly only applied in 35kV and following grade, and high pressure, extra high voltage system are because its capacity is large, and the energy discharged during short trouble is large, higher to the performance requirement of protection box.Even if there is the protection box being applied to extra high voltage system, be also the hermetic dead hermetically-sealed constructions in two ends, this from medium voltage network application protection box repacking product, do not consider the problem that extra high voltage system transition joint earth connection is drawn, install very difficult.Meanwhile, this kind of product can not solve the problem of transition joint heat radiation, and connector temperature has a strong impact on ampacity after raising.Laboratory simulation joint short trouble is the most reliable mode of checking protection box protective value, but due to its technical difficulty large, cost is high, does not also have producer to do so domestic.
Summary of the invention
Object of the present invention be exactly provide that a kind of compact conformation is small and exquisite to overcome defect that above-mentioned prior art exists, quality is light, the protective device for high pressure, ultra-high voltage cross-linking cable transition joint of environmental protection.
Object of the present invention can be achieved through the following technical solutions:
For a protective device for high pressure, ultra-high voltage cross-linking cable transition joint, it is characterized in that, this protective device comprises housing and obturator, and described housing is tubular, is divided into three sections, is respectively the left side section, interlude, the right section that connect successively; Described cable intermediate joint is located in housing, and described obturator is located between housing and cable intermediate joint.
Described left side section, interlude, the right section are divided into upper and lower two halves, this upper and lower two halves is equipped with outward extending shirt rim, this shirt rim is provided with hole, and the two halves up and down of left side section, interlude, the right section is linked together by the hole penetrated on shirt rim by bolt.
The latter half of described interlude is provided with two boss, this boss is provided with shrinkage pool, described transition joint is fixed on joint anchor ear, described joint anchor ear is fixed in the shrinkage pool of boss, described boss is fixed on cable bearer, joint anchor ear, boss, cable bearer is fixed together by bolt.
Described left side section and the right Duan Junxiang central reduction form round-meshed baffle plate.
The diameter of described circular hole is 50 ~ 75% of external diameter.
Described obturator is the ceramic fibre of fiber melt more than 1600 degree.
Described housing adopts expoxy glass Steel material.
The thickness of described housing is 1 ~ 2cm.
Compared with prior art, the present invention has the following advantages:
1) adopt glass-reinforced plastic material, quality is light, and environmental protection, have passed through environment measuring certification;
2) three-stage structure, this compact conformation is small and exquisite, is convenient to transport and installs;
3) have a boss in the middle of, can simple realization joint, protection box and the link of support;
4) non-dead hermetically-sealed construction, does not affect current-carrying capacity of cable, and did experimental verification;
5) laboratory environment innovation simulation short trouble, checking protection box protective value.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram;
Fig. 2 is plan structure schematic diagram;
Fig. 3 is the DD face cutaway view of Fig. 1;
Fig. 4 is the part A cutaway view after installing.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
The environment installed for high pressure, ultra-high voltage electric cable joint is general all narrow, and therefore protect the structure of box to want compact small and exquisite, quality is light, is convenient to mounting box transport.Meanwhile, cable joint operationally can shake, and simple and conveniently must realize the fixing of joint.
High pressure, extra-high-tension cable transition joint generally have earth connection to need to pass in protection box, therefore need to solve the problem how earth connection passes protection box.Transition joint simultaneously operationally can produce heat, if heat can not shed in time, connector temperature can be made to raise further, will affect the ampacity of cable.
When high pressure, extra-high-tension cable normal transmission, if there is magnetic material around, then can produce eddy current, consume power grid energy, neighbouring product of metal material also needs reliable ground, when ground connection is unreliable or destroyed time, easily breaks down.
As shown in Figure 1, Figure 2, Figure 3, Figure 4, for a protective device for high pressure, ultra-high voltage cross-linking cable transition joint, this protective device comprises housing and obturator 8, and described housing is tubular, be divided into three sections, be respectively the left side section A, interlude B, the right section C that connect successively; Described cable intermediate joint 5 is located in housing, and described obturator 8 is located between housing and cable transition joint 5.Described left side section A, interlude B, the right section C are divided into upper and lower two halves, this upper and lower two halves is equipped with outward extending shirt rim 1, this shirt rim 1 is provided with hole, and the two halves up and down of left side section A, interlude B, the right section C is linked together by the hole penetrated on shirt rim by bolt.The latter half of described interlude is provided with two boss 2, this boss 2 is provided with shrinkage pool, described transition joint 5 to be fixed on joint anchor ear 4, described joint anchor ear 4 is fixed in the shrinkage pool of boss, described boss is fixed on cable bearer 3, joint anchor ear 4, boss 2, cable bearer 3 is fixed together by bolt.Described left side section and the right Duan Junxiang central reduction form round-meshed baffle plate 6, and cable 7 is through baffle plate 6.
