Abstract
The utility model relates to an electric current sensor. An insulating flexible frame is arranged on a flexible magnetic stripe and enameled wires are wound around the insulating flexible frame, wherein, both ends of the flexible magnetic strip can be combined together. The ends of the flexible magnetic strip are provided with mounting holes through which the flexible magnetic strip can be combined together. The ends of the insulating flexible frame are provided with baffle platforms and the outer side of the wound enameled wires is provided with an insulating layer. The turn number of the enameled wires wound around the insulating flexible frame is a quotient that the rated current value of monitored wires is divided by the rated current value of the enameled wires. The utility model has the advantages of compact structure, convenient fabrication, small limit on the turn number of the enameled wires and high monitoring performance.
Description
The utility model relates to the device of monitoring electric power conductor electric current, is a kind of current sensor.
The iron core of existing current sensor is ring-like framework, as shown in Figure 1, the frame that twines enameled wire at needs has added insulation framework, and on insulation framework, be wound with enameled wire, owing to be subjected to the influence of ring-like framework, when twining enameled wire, enameled wire must pass in the middle of ring-like framework repeatedly, speed of wrap is affected, thereby influences production efficiency; And the number of turn of enameled wire is restricted, and its monitoring performance is affected.
In view of the problem of above-mentioned existence, the purpose of this utility model is to design a kind of high current sensor of performance of being convenient to make, monitor.
The purpose of this utility model realizes by following measure: insulation cartilage frame is arranged on the soft magnetic stripe of this current sensor, be wound with enameled wire on insulation cartilage frame, the soft magnetic stripe two ends can be installed together.
The mounting hole that the soft magnetic stripe two ends can be installed together is arranged in above-mentioned soft magnetic stripe end.
There is the retaining platform end at above-mentioned insulation cartilage frame.
In the above-mentioned enameled wire that the winds outside insulation course is arranged.
The number of turn of twining enameled wire on above-mentioned insulation cartilage frame is the quotient of the load current value of monitored lead divided by the load current value of enameled wire.
The load current value of above-mentioned enameled wire is 0.001 to 0.030 ampere.
Accompanying drawing 1 is the structural representation of the ring-like framework iron core of existing current sensor;
The structural representation that accompanying drawing 2 launches for the utility model most preferred embodiment,
The structural representation of the scheme one that accompanying drawing 3 is installed together for the soft magnetic stripe two ends in the accompanying drawing 2,
The structural representation of the scheme two that accompanying drawing 4 is installed together for the soft magnetic stripe two ends in the accompanying drawing 2,
Coding in the accompanying drawing is respectively: 1 is soft magnetic stripe, and 2 are insulation cartilage frame, and 3 is enameled wire, and 4 is mounting hole, and 5 are the retaining platform, and 6 is insulation course, and 7 is bolt.
Below in conjunction with most preferred embodiment and accompanying drawing the utility model is further described:
As shown in Figure 2, insulation cartilage frame 2 is arranged on the soft magnetic stripe 1 of this current sensor, be wound with enameled wire 3 on insulation cartilage frame 2, soft magnetic stripe 1 two ends can be installed together.
Wherein: preferably there is the mounting hole 4 that the soft magnetic stripe two ends can be installed together soft magnetic stripe 1 end, and by bolt soft magnetic stripe 1 two ends is installed together, shown in accompanying drawing 3 and 4; As shown in Figure 2, retaining platform 5 is preferably arranged, can prevent from like this to come off by the enameled wire 3 of insulation cartilage frame 2 ends in the end of insulation cartilage frame 2; As shown in Figure 2, insulation course 6 is preferably arranged, can prevent enameled wire 3 electric leakages like this, play safety effect in enameled wire 3 outsides that wind; As shown in Figure 2, the number of turn of twining enameled wire 3 on insulation cartilage frame 2 is preferably the quotient of the load current value of monitored lead divided by the load current value of enameled wire, and the load current value of enameled wire 3 is preferably 0.001 to 0.030 ampere.
Soft magnetic stripe in the utility model is to be made by the higher soft magnetic material of magnetoconductivity, and has certain intensity also flexible, as: siliconized plate.
During use: monitored lead is passed soft magnetic stripe 1 constitute circle, when the electric current of monitored lead changes, the induction current of enameled wire 3 is also changed, so just can utilize induction current to monitor or carry out control and treatment.
The utility model compact conformation, be convenient to make, and the number of turn of enameled wire is restricted little, thereby has improved the monitoring performance.
