Abstract
The utility model relates to a mutual current inductor with a guide rod threading in, which comprises a shell (1), a secondary winding (2) provided with an iron core, a voltage extracting piece (3), a pedestal (4) and output terminals (s1, s2, U), wherein the shell (1) in the shape of a racket is provided with a punched hole (5) at the center; the supporting tube (6) is disposed at the periphery of the punched hole (5); the voltage extracting piece (3) is disposed on the supporting tube (6); the secondary winding (2) with circular ring shape is disposed in the shell (1) and sealed with insulating material (7); the pedestal (4) is buckled with the shell (1); and the output terminals (s1, s2, U) are mounted below the pedestal (4). The output terminals (s1, s2) are respectively connected to the two ends of the secondary winding coil, and the output terminal U is connected to the voltage extracting piece (3). The mutual current inductor with a guide rod threading in is an ideal low voltage anti-thief electric metering device.
Description
Technical field:
The utility model belongs to the low-temperature measurement device, is meant guide rod through type current transformer.
Background technology:
Existing low-temperature measurement device is that primary cable is caused the gauge table case from transformer conducting bar, connects the table metering through current transformer again.Because transformer conducting bar is in and exposes, and connects power load herein, then forms electric leakage as not connecing gauge table.Solving leaks electricity must be installed in current transformer the position of conducting rod.Existing current transformer must increase by one group of connecting rod because structure is limit on transformer conducting bar, current transformer is installed on the connecting rod.It is improper to install, and will cause the heating of connecting rod and transformer conducting bar, and it is big more to load, and temperature rise is high more, gently then burns out current transformer, and is heavy then burn out transformer, brings accident potential to equipment operation.
Summary of the invention:
The utility model is in order to increase by one group of connecting rod on the conducting rod that overcomes existing current transformer, current transformer must be installed on the connecting rod again, just in case it is improper to install, will cause the heating of connecting rod and transformer conducting bar, gently then burn out current transformer, heavy then burn out transformer, bring accident potential to equipment operation.
A kind of guide rod through type current transformer now is provided, forms by having secondary winding, voltage extracting sheet, base and lead-out terminal unshakable in one's determination, wherein, housing is racket shape, a perforation is established at the center, and keyhole periphery is provided with stay pipe, and the voltage extracting sheet is placed on the stay pipe; Have secondary winding unshakable in one's determination and be annular, be placed in the housing, and seal with insulating material, base and housing fasten, and lead-out terminal is fixed on the base below.During use, the perforation with transformer conducting bar directly inserts current transformer screws with nut, and guide rod through type current transformer is fixed on the transformer conducting bar.Transformer conducting bar has served as the primary winding of current transformer, and the voltage extracting sheet on the current transformer is as the extraction source of voltage signal, and secondary current and the voltage signal all terminal by current transformer are transferred to the gauge table metering as output.
Beneficial effect: owing to changed the current transformer structure, transformer conducting bar directly inserts the perforation of current transformer, screws with nut, and guide rod through type current transformer is fixed on the transformer conducting bar.Avoided current transformer load big, temperature rise and burn out current transformer or burn out the accident of transformer.
