Abstract
The utility model provides a current mutual inductor, casing (1), magnetic coil (2), epoxy glue (3) and primary power cource line (4), casing (1) one end is uncovered, magnetic coil (2) suit is in casing (1), be equipped with centre bore (5) in casing (1), the primary power cource line passes centre bore (5), epoxy glue (3) coating is on magnetic coil (2), and bond with the one end of casing (1) is sealed, centre bore (5) are passed on the outer wall in casing (1) in primary power cource line (4). The utility model has the advantages that: 1, once less with secondary electric capacity discreteness, the capacitance value is dropped to within the 20PF, 2, after increasing the casing, epoxy glue is convenient for seal and is glued, avoids extravagant, 3, has saved and has wrapped the insulating cement step, save time, laborsaving, save labour, 4, product insulating reliability is high.
Description
Technical field
The utility model is specifically related to a kind of current transformer.
Background technology
At present, 1, existing current transformer brings sealed magnetic core coil by wrapping insulating cement, this mode is time-consuming, effort.2, primary line does not have positioner, and primary line location is cumbersome; 3, dielectric voltage withstand grade is not enough, and the withstand voltage percent defective in production process is high, poor reliability that product is withstand voltage; 4 is once comparatively large with secondary electric capacity discreteness, and capacitance is greater than more than 30pF.
Summary of the invention
The purpose of this utility model is bring sealed magnetic core coil by wrapping insulating cement for current 1, existing current transformer, and this mode is time-consuming, effort.2, primary line does not have positioner, and primary line location is cumbersome, and labour cost is high.3, dielectric voltage withstand grade is not enough, and the withstand voltage percent defective in production process is high, poor reliability that product is withstand voltage; 4 is once comparatively large with secondary electric capacity discreteness, and capacitance is greater than the deficiency of more than 30pF, and provides a kind of current transformer.
A kind of current transformer of the utility model, it comprises housing, magnetic coil, epoxide-resin glue and primary power source line, shell one end is uncovered, magnetic coil is sleeved in housing, be provided with centre bore in housing, primary power source line is through centre bore, and epoxide-resin glue is coated on magnetic coil, and be sealing adhesive with one end of housing, primary power source line passes centre bore around on the outer wall of housing.
It also has a pair one time lead-out wire, housing has a pair location notch, and the two ends of primary power source line are connected with a pair one time lead-out wire respectively, and insert in a pair location notch on housing.
The utility model advantage is: 1, once less with secondary electric capacity discreteness, within capacitance is down to 20pF; 2, after increasing housing, epoxide-resin glue is convenient to sealing, avoids waste; 3, eliminate wrapping insulating cement step, save time, laborsaving, saving of labor; 4, product insulating reliability is high.
