Abstract
The utility model relates to a current transducer, which comprises a casing, a current transformer (CT) a circuit board, etc., and is characterized in that a single-turn cored current transformer (CT) is adopted, the current transformer (CT) is fixed on the casing of a transducer, a wire threading hole is arranged at the corresponding position to the inner diameter of the single-turn cored current transformer (CT) on the casing, a connecting terminal is not required, and when being used, only the input current conducting wire is got through the wire threading hole according to the assigned direction. The utility model does not require an input current signal connecting terminal, therefore the structure is simple, the connecting is easy, and the utility model can be widely applied to power automation field and other fields.
Description
The utility model relates to the particularly inner current transducer that uses single turn punching CT of a kind of current transducer.
Current transducer in the past or have other class transmitter of current segment, all adopt connection terminal that the current signal of input is inserted transmitter, every phase current needs two connection terminals (electric current into and out of end), if three-phase current input, then need 6 connection terminals, the quantity that this has not only increased connection terminal increases the trouble of wiring, also can increase the chance of makeing mistakes in the wiring process.
It is a kind of simple in structure, easy for installation that the utility model provides, the current transducer that wiring is difficult for makeing mistakes.
The utility model is to realize like this, current transducer is made up of shell, single turn punching CT and circuit board, be characterized in: single turn punching CT is fixed on the transmitter shell, on the transmitter shell, have through wires hole with the endoporus opposite position of single turn punching CT, through wires hole is circular, the aperture is not less than the endoporus of punching CT, can pass through easily with the current lead of guaranteeing to import, during use, only the current lead of input need be passed center hole according to the direction of appointment and get final product.The shell of transmitter is made with hard insulation; Circuit board is used to import, the conversion of output signal.
The utility model is not because need the connection terminal of input current signal, so simple in structure, easy-to-connect can be widely used in fields such as power automation.
Accompanying drawing 1 is a synoptic diagram of the present utility model, and wherein: [1] is the shell of transmitter; [2] be single turn punching CT; [3] be outside input current lead; [4] be circuit board, [5] are the threading circular hole on the transmitter shell; [6] be the output wiring terminal of transmitter.
Below in conjunction with schematic illustration the utility model is done concrete operation instruction.
Punching CT[2 among the figure] all be fixed on the shell [1] shell [1] and punching CT[2 with circuit board [4]] the corresponding position of endoporus has through wires hole [5], through wires hole is a circular hole, diameter and punching CT[2] endoporus consistent, shell is made by ambroin.During use, outside input current lead [3] at first passes the through wires hole [5] of shell [1] one side according to a certain direction, penetrates punching CT[2 immediately] endoporus, the through wires hole [5] from the inner opposite of transmitter passes again, inserts former loop then; Punching CT[2] output signal line be connected on the circuit board [4], after the processing through circuit board [4], receive the output wiring terminal [6] on the shell [1], form the output signal of transmitter.
Claims (2)
