Abstract
The invention discloses an integrated output terminal structure of a capacitive voltage divider, comprising a medium voltage output terminal. The medium voltage output terminal is educed from the bottom of a ceramic bushing of the capacitive voltage divider, which is provided with a flange, and comprises a medium voltage output copper rod and an epoxy resin casting wrapping outside the medium voltage output copper rod, a copper net is pre-embedded in the epoxy resin casting as a low voltage output terminal, and a low voltage output port which is connected with the copper net is also arranged on the epoxy resin casting. The medium voltage output terminal and the low voltage output terminal of the integrated output terminal structure of the capacitive voltage divider are in an integrated structure, thereby efficiently lowering a local discharge level under the highest running voltage; and an external insulating layer is the epoxy resin casting, therefore, the invention has the advantages of simple structure, low local discharge level of equipment and high safety.
Description
Technical field
The present invention relates to a kind of power equipment, particularly relate to a kind of integrated output terminal structure of capacitive voltage divider with low local discharging level.
Background technology
At present, capacitive divider is widely used in the power equipment as a kind of voltage transformer (VT), along with improving constantly of development of technology and product electric pressure, the user requires more and more higher to the performance index of electric product, local discharging level is one of them very important index, shelf depreciation is meant that product is under certain applied voltage effect, the discharge that weakness in the insulation takes place, though can not forming the penetrability of whole insulation immediately, shelf depreciation punctures, but product is in long-time running, and the sustainable development of shelf depreciation can cause the damage of insulation gradually, impel insulation ag(e)ing, even cause the puncture of whole insulation at last.
See also shown in Figure 1, Fig. 1 is the structural representation of the lead-out terminal of traditional capacitive divider, the porcelain bushing shell of traditional capacitive divider, the bottom of described porcelain bushing shell is equipped with flange 3, the bottom of described flange 3 is drawn middle pressure lead-out terminal 1 and low-voltage output 2 disconnected from each other respectively, press lead-out terminal 1 to comprise middle output copper rod 11 and the coated insulation polytetrafluoroethylmaterial material layer 12 outside middle pressure output copper rod 11 of pressing in described, described low-voltage output 2 comprises that low pressure output copper rod 21 and coated epoxy outside low pressure output copper rod 21 water foundry goods 22, the mesolow lead-out terminal of this structure is under the highest working voltage of equipment, local discharging level is bigger than normal, can cause the damage of insulation course, have certain potential safety hazard.
