Description
Technical Field
The utility model relates to an electric power fitting, especially a dizzy type quadripartion conductor equipment fastener is prevented in combination that high voltage class transformer substation used.
Background
In recent years, the power industry in China is rapidly developed, the requirements on the quality and the performance of electric power fittings are higher and higher, and the surface field intensity of the fittings is higher and higher in high-altitude areas, particularly in ultrahigh-voltage transformer substations of 330kV and above. The existing common equipment wire clamp generally adopts a binary-splitting structure, if the cable clamp is a quadruple-splitting cable clamp, two sets of binary-splitting wire clamps are needed, a drainage plate of the equipment wire clamp is in direct contact with equipment and is arranged on a panel of the equipment by a bolt, and the bolt is exposed outside and has no protection, so that discharge is easily generated.
In order to adapt to the development of electric power construction, the through-current capacity of equipment wire clamp hardware needs to be continuously improved, and meanwhile, the problem that discharge is caused by too high field intensity due to too small diameter of a bolt at the joint of an equipment connecting wire and equipment needs to be reduced, so that the effects of energy conservation and noise reduction are achieved.
Disclosure of Invention
An object of the utility model is to provide a prevent dizzy type quadripartion conductor equipment fastener is prevented in combination that dizzy performance is good, through-flow performance is high.
The utility model discloses realize that the technical scheme that above-mentioned purpose was taken is: a combined anti-corona four-split wire equipment clamp comprises a junction box; the method is characterized in that: the wire clip also comprises four wire clip bodies; the junction box is of a hollow structure with an opening on one side, an anti-corona cap is arranged on the junction box, and two wire clamp bodies are respectively arranged on the left side and the right side of the outer surface of the junction box.
Two wire clamp bodies are arranged and installed on the left side and the right side of the outer surface of the junction box according to the upper direction and the lower direction; the anti-corona cap is of a spherical crown structure integrally protruding out of the left side and the right side of the junction box.
Integrally casting and molding a junction box of the equipment wire clamp; the wire clamp body is fixedly connected to the outer surfaces of the left side and the right side of the junction box through bolts. The bottom surface of terminal box is equipped with the bolt hole, during the use, through bottom surface bolt with terminal box bottom surface and substation equipment, like fixed connection such as circuit breaker, voltage transformer, current transformer. The bolt is arranged in the junction box to avoid discharging.
In the prior art, the same-phase four-split conductor is realized by two sets of two-split double-conductor equipment wire clamps; the utility model discloses replace two original two binary divisions two wire equipment fastener by installing four fastener bodies on the terminal box, realize the connection that equipment adopted the four-split wire.
The utility model provides a high voltage level transformer substation split conductor connection problem, improved corona initial voltage simultaneously, it is energy-conserving effectual, simple to operate. The utility model discloses having used at the above ultra high voltage level transformer substation of 330kV, reduced the noise that the transformer substation produced because the corona effectively. The equipment wire clamp is connected to equipment through the hollow corona-proof box of the middle basket, the corona-proof cap of the spherical cap type structure arranged on the junction box has a voltage-sharing effect on the whole hardware fitting, the electric field intensity on the surface of the hardware fitting is reduced, corona is not generated, the corona starting voltage is improved, therefore, the energy-saving and noise-reducing effect is achieved, and meanwhile, the large-current conveying capacity is improved due to the adoption of the four-split structure.
