[background technology]
At present, (sulfur hexafluoride current mutual inductor of 110kV～500kV) as the major product of High-Voltage Electrical Appliances at coil aspect the fixing and product insulation, all kinds of insulators of main application are as immobilization carrier, but this insulation system mode is very high to the requirement of strength of insulating basin, present any technique can't ensure that all the manufacturing intensity of insulating basin reaches the requirement of design, cause the insulation property of product and the fixation of coil is reduced greatly, more make the Product transport process cause certain damage to product simultaneously.
[utility model content]
The purpose of this utility model is to provide a kind of double bracing insulation system of sulfur hexafluoride current mutual inductor, to solve the problems of the technologies described above.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of double bracing insulation system of sulfur hexafluoride current mutual inductor comprises the body, coil and cross-shaped insulating frame; Described coil is encapsulated in the radome; Described body bottom is provided with insulating basin, is fixed with radome on the insulating basin; The top of radome is provided with a upper flange, and the cross-shaped insulating frame center is fixedly connected with described upper flange, and the cross-shaped insulating frame end is fixedly connected with the body.
The utility model further improves and is: described double bracing insulation system also comprises an end socket, end socket be fixed in body top and and the body between form a confined space, described radome accommodate with described confined space in.
The utility model further improves and is: be filled with sulfur hexafluoride gas in the described confined space.
The utility model further improves and is: the cross-shaped insulating frame end is fixedly connected with the body by bolt.
The utility model further improves and is: end socket and body junction are provided with grading ring.
With respect to prior art, the utlity model has following advantage: the utility model arranges the radome bottom that insulating basin will be equipped with coil and is fixed by being arranged on body bottom, is fixed by the top of cross-shaped insulating frame with radome; Coil no matter at product in upright process, or during the product accumbency, all the coil of product played most important fixation; The cooperation of the utility model by two kinds of insulating supporting structures makes the fixing more firm of coil, and no matter which type of product runs into is impacted, the assurance of maximum possible the fail safe performance during Product transport can not be affected.
[description of drawings]
Fig. 1 is the schematic diagram of the double bracing insulation system of the utility model sulfur hexafluoride current mutual inductor.
[embodiment]
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
See also shown in Figure 1ly, the double bracing insulation system of a kind of sulfur hexafluoride current mutual inductor of the utility model comprises the body 2, end socket 5 and a cross-shaped insulating frame 6; The bottom of the body 2 is provided with lower flange, and lower flange is provided with insulating basin 1, and coil is sealed in the radome 8, and radome 8 is fixed on the insulating basin 1; Radome 8 is provided with upper flange, and upper flange and the body 2 that cross-shaped insulating frame 6 passes radome 8 are bolted to connection; After fixing cross-shaped insulating frame 6, with end socket 5 by the top of bolted in the body 2.Cross-shaped insulating frame 6 usefulness insulating material are made, and solve simultaneously high and low Insulation Problems and the fixation problem of coil.
The body 2 and end socket 5 have vital impact to the utility model dual-support structure mode; The body 2 and end socket 5 are respectively by casting mould, and disposable casting, foundry goods be through machining, in order to sealing and other performance that guarantees product integral body, and guarantee its inside with the sulfur hexafluoride gas of normal pressure year leak rate less than set-point.
The support of cross-shaped insulating frame 6 four directions has been played vital effect to the insulation insulation property of this product, the supporting role of four direction supports insulative bar has been arranged, not only make the insulation of current transformer inside high, the insulation property of low-pressure end are effectively guaranteed, and played again the gravity that bears coil itself, with coil in lateral impact forces, if this impulsive force surpasses certain scope, can be to the overall performance product significant impact of product, may cause the insulation of product to be subject to heavy damage, make height, the low pressure conducting, can there be larger damage to secondary device, bear simultaneously the impulsive force that the coil acceleration that all directions are subject in transportation produces, may be on the impact of current transformer generation thereby effectively solved transportation.
The double bracing insulation system of the utility model sulfur hexafluoride current mutual inductor, make sulfur hexafluoride current mutual inductor guarantee on the one hand every insulation property, on the other hand again can be in the transportation environment that jolts, performance in the time of can better keeping product export, making the X factor that occurs in the Product transport process be reduced to minimum to the impact that the performance of product produces, also is a kind of effective means that ensures the sulfur hexafluoride current mutual inductor performance.
The utility model has effectively solved the problem of creepage distance and support coils by a high-intensity insulating basin is set, and is provided with a radome on the top of insulating basin, is used for solving the inhomogeneous phenomenon of this position electric field pole.
