Abstract
The utility model discloses a zero-sequence mutual inductor through-hole connecting conductive device special for a leakage breaker which consists of conductive bars, a zero-sequence mutual inductor and an insulation block. Four through-hole connecting devices (9) separated by the insulation block (2) are arranged in through holes of the zero-sequence mutual inductor (1), each inlet and each outlet (namely both ends) are respectively connected with one conductive bar (3), one conductive bar (4), one conductive bar (5) and one conductive bar (6) and one output conductive copper bar (10), one output conductive copper bar (11), one output conductive copper bar (12) and one output conductive copper bar (13), the conductive bars and the output conductive copper bars are fixed by bolts (8), each output conductive copper bar of the device is taken as the output connection of the leakage breaker.
Description
Technical field
This utility model relates to a kind of and the matching used multiduty electric switch of low voltage electric network protective device, and perforation connects a kind of device that conducts electricity as zero-sequence transformer in residual current circuit breaker.
Background technology
Connect in the electric installation at existing numerous residual current circuit breaker zero-sequence transformer through hole, have that assembling is difficult, a defective such as temperature rise height during work.
Summary of the invention
The technical scheme that the utility model adopted is: this device connects the deficiency of electric installation to existing various residual current circuit breaker zero-sequence transformer through holes, design a kind of high material of insulation property that adopts and connect electric installation, form by busbar, zero-sequence transformer, through hole coupling arrangement and collets as the zero-sequence transformer through hole of insulating element.In zero-sequence transformer, pick out 4 pairs of busbars by 4 through hole coupling arrangements, 4 through hole coupling arrangements are isolated with 1 collets.
When the zero-sequence transformer through hole connects electric installation work, can make full use of the through hole sectional area, make the busbar that passes this hole reach the most effective maximum conductive area, thereby improve conducting function, reduce temperature rise, increase electric current.
The beneficial effects of the utility model are, when cooperating residual current circuit breaker work, it is comparatively convenient to install, and entire area (space) is dwindled.
