A transformer for underground electric power line with switch to be able to interruption or supply the high voltage power on the underground electric power line

摘要

The present invention was built in the home and industry to block the high voltage power in the transformer can be easily replaced the transformer at a transformer failure installed at underground cable in order to provide power to the complex switch the high voltage transformer on a underground replaced with a new transformer, or a high-pressure side provided with the high voltage switching means for enabling the operation with uninterrupted if you want to cut off the power when the power operation and the high pressure side and low pressure side all bonds are easily elbow to the transformer outside on to other underground It relates to a transformer in which the insert and the elbow terminal fixing underground. Aging of the home and the transformer is used as a means of lowering the voltage to a low voltage supply of household and industrial 220 / 380V in the industrial electric power supply when high voltage of 22.9kV supplied through the transmission line from the power plant, the transformer is being used or If to be a substitution in when the error (failure) in the transformer by the overload to operate normally transformer to replace the transformer of the ground track, the past achieved by working with uninterrupted by the uninterruptible transformer replacement vehicle for a underground cable has such since the execution of the operation to disable the power failure is inevitable because it results in a considerable inconvenience to the home or enterprise the present invention relates to a transformer to the underground cable to enable operations as uninterrupted by built-in high voltage switching means to the internal transformer.; [Index term;; SF ₆ gas as a transformer switchgear, underground, UPS transformer replacement
