Abstract
The utility model provides a 500kV sulfur hexafluoride current transformer, which is characterized in that the top of the housing is provided with a supporting insulator installation through hole, the periphery of the installation through hole is connected with a matched flange, the flange is provided with a through hole, a bursting disc device is installed at the periphery of the through hole, the upper top surface of a secondary coil shielding barrel is connected with a supporting insulator fixed connection device symmetrical to the bottom surface of the secondary coil shielding barrel, the fixed connection device and the periphery of the housing top installation hole are connected via another supporting insulator. The 500 kV sulfur hexafluoride current transformer is advantaged by fixation of the secondary coil shielding barrel via upper and lower dual supporting insulators, firmness and reliability, as well as prevention of breakage phenomenon of supporting insulators during horizontal transportation.
Description
Technical field
The utility model relates to a kind of electric power mutual-inductor, particularly a kind of 500kV sulfur hexafluoride current mutual inductor.
Background technology
The secondary coil shielding cylinder of existing 500kV sulfur hexafluoride current mutual inductor is to be fixed on the flange seat by a supporting insulator.Because product is too high, the transportation of must droping to the ground during carrying, when droping to the ground, the coil shielding cylinder forms cantilever design in device body housing, and phenomenon of rupture takes place in supporting insulator easily when running into severe turbulence in transit.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned weak point, and a kind of coil shielding cylinder is fixed, the 500kV sulfur hexafluoride current mutual inductor of transportation safety and provide.
The purpose of this utility model is achieved in that a kind of 500kV sulfur hexafluoride current mutual inductor, comprise housing, base, sleeve pipe, the primary conductive bar, the secondary coil shielding cylinder, supporting insulator, it is characterized in that case top has supporting insulator through hole is installed, bore periphery is installed is connected with the ring flange that is complementary, have through hole on the ring flange, blasting piece device is installed above the bore periphery, end face is connected with the supporting insulator fixed connection apparatus with its bottom surface symmetry on the secondary coil shielding cylinder, and this fixed connection apparatus is installed between the bore periphery with case top and is connected another supporting insulator.
The utility model adopts fixedly secondary coil shielding cylinder of upper and lower double bracing insulator owing to adopt above architecture advances, and is solid and reliable, and the supporting insulator phenomenon of rupture takes place when stopping to drop to the ground transportation.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Now illustrated embodiment is made detailed description to the utility model in conjunction with the accompanying drawings.
As shown in Figure 1, the 500kV sulfur hexafluoride current mutual inductor comprises housing 1, base 2, sleeve pipe 3, primary conductive bar 4, secondary coil shielding cylinder 5, supporting insulator 6, housing 1 top has supporting insulator through hole 7 is installed, through hole 7 ports are installed outstanding fillet 8 is arranged, be connected with the ring flange 9 that is complementary by bolt above the fillet 8, have through hole 10 on the ring flange 9, above through hole 10 peripheries blasting piece device 11 is installed, end face is connected with the supporting insulator fixed connection apparatus with its bottom surface symmetry on the secondary coil shielding cylinder 5, promptly end face welds a projection clamping ring 12 on secondary coil shielding cylinder 5, by bolted flange dish 13, be connected another supporting insulator 14 by bolt respectively between the fillet 8 of ring flange 13 and case top installation through hole 7 in the clamping ring 12.
