In traditional establishment of sending the power transformation unit, usually instrument transformer and regulator cubicle are split installation, and carry out between the two connection by cable.For satisfying the regulation of cable installation code, its stube cable needs certain arc radius, therefore, makes to exist certain distance between instrument transformer and the regulator cubicle.
The above-mentioned traditional instrument transformer and the installation set-up mode of regulator cubicle exist certain defective or deficiency, it mainly shows as, this mode makes send the volume of power transformation unit excessive, in addition, because outside the cable of connection instrument transformer and regulator cubicle is exposed to, fail safe is reduced greatly, though, taked certain insulation measures, still, after cable service time is long, the fail safe of insulation measures will reduce, especially in hot, rainy climatic environment, all the more so, give and use, safeguard and caused certain difficulty.In view of this, how to overcome above-mentioned defective or deficiency, become one of major issue that high force feed power transformation production industry needs to be resolved hurrily already.
Summary of the invention
The objective of the invention is to defective that volume is excessive, fail safe is lower or deficiency that the installation set-up mode at above-mentioned traditional instrument transformer and regulator cubicle exists, and provide a kind of high-voltage electrical cabinet of connecting mutual inductor, this high-voltage electrical cabinet is directly pegged graft by the conductive plug that fixedly installs on electrically conductive socket that fixedly installs on its body and instrument transformer body, make power transformer become a part of regulator cubicle, can reduce volume, improve fail safe.
For achieving the above object, the high-voltage electrical cabinet of a kind of connecting mutual inductor of the present invention, it comprises the high-voltage electrical cabinet body, and described high-voltage electrical cabinet body inboard is provided with an electrically conductive socket, and the socket of this electrically conductive socket is positioned on the high-voltage electrical cabinet body surface; Be provided with conduction connector in the socket of described electrically conductive socket, this conduction connector connects with the interior corresponding power input of described high-voltage electrical cabinet body; Described high-voltage electrical cabinet body is provided with an instrument transformer, and this instrument transformer is provided with connector; The grafting of described connector and described socket; The skin of described connector is an insulator, and its inside is provided with electric conductor, and this electric conductor and described conduction connector are pegged graft; Described electric conductor is connected with the output of described instrument transformer.
In the technique scheme, be arranged on the connector on the instrument transformer body and the electrically conductive socket that is installed on the high-voltage electrical cabinet body all has the good insulation performance protective value.When the power transformation unit is sent in establishment, because instrument transformer directly is plugged on the high-voltage electrical cabinet body by connector, make whole high-voltage electrical cabinet form an integral body, therefore, do not need to send the power transformation unit sets up as traditional, the cable of establishing by other is connected instrument transformer with the high-voltage electrical cabinet body, and, eliminated the distance of past between instrument transformer and high-voltage electrical cabinet body.
As shown from the above technical solution, the present invention is by installing a connector on the instrument transformer body, itself and high-voltage electrical cabinet body are directly pegged graft, thereby need not to use the stube cable outside being exposed to, and eliminated original high-voltage electrical cabinet body and the distance between the instrument transformer, thereby can dwindle the volume that send the power transformation unit effectively, fail safe is largely increased, even in rainy climatic environment, also can normally use, safeguard.
Below in conjunction with drawings and Examples, the present invention is further described in detail.
