Abstract
The utility model discloses a zero-sequence mutual inductor through-hole connecting conductive device special for an earth leakage circuit 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) of the through-hole connecting devices (9) are respectively connected with a conductive bar (3, 4, 5, 6) and an output conductive copper bar (10, 11, 12, 13). The conductive bars and the output conductive copper bars are fixed by bolts (8), and each output conductive copper bar of the device is taken as the output connection of the earth leakage circuit 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 ZCT in RCCB.
Background technology
Connect in the electric installation at existing numerous RCCB ZCT 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 RCCB ZCT through holes; Design a kind of high material of insulation property that adopts and connect electric installation, form by busbar, ZCT, through hole coupling arrangement and collets as the ZCT through hole of insulating element.In ZCT, pick out 4 pairs of busbars by 4 through hole coupling arrangements, 4 through hole coupling arrangements are isolated with 1 collets.
When the ZCT 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 effect of the utility model is, when cooperating RCCB work, it is comparatively convenient to install, and entire area (space) is dwindled.
