Description

Flexible Roche coil capable of being opened and closed

Technical Field

An openable flexible Rogowski coil belongs to the technical field of Rogowski coils.

Background

The Rogowski coil is a sensor which is commonly used at present for measuring current, when the Rogowski coil is used, an output signal is a differential of the current to time, and the input current can be really restored through a circuit for integrating an output voltage signal. Since the rogowski coil needs to pass through a cable measured by the rogowski coil during measurement, the rogowski coil is generally open and is generally placed in a shell, one end of the shell is hinged and the other end of the shell is open, and the open end of the shell corresponds to the open end of the rogowski coil, so that when the open end of the shell is closed, the two ends of the rogowski coil are butted to form a closed loop.

Generally, the rogowski coil is in two-section type, when the shell is closed up and down, two openings of the rogowski coil are simultaneously butted to form a closed state, and in order to improve the waterproof and moisture-proof characteristics of the rogowski coil, the rogowski coil at two ends needs to be respectively solidified in corresponding shells. However, the two-segment rogowski coil has an influence on the measurement sensitivity of the rogowski coil at two openings, and the two-segment rogowski coil needs to be connected with one segment of the rogowski coil through a lead wire, so that the assembly complexity is increased, and the efficiency is low.

In order to reduce the influence of the two-segment rogowski coil on the measurement sensitivity, a one-segment rogowski coil (only provided with one opening) is also available in the market at present, but the following defects generally exist in the conventional one-segment rogowski coil:

(1) the pin joint of traditional open-close type rogowski coil is located the tip of casing, therefore the shell is at the in-process that opens and shuts, and the coil is located one section of articulated department and can takes place to buckle to because current product open and shut the angle great, so the coil is located one section of articulated department length longer, to the requirement of coil length when the adaptation is gone up, down the casing open and shut, therefore the coil is located one section of articulated department and generally is located the casing outside, not only causes the damage easily, and influence the product pleasing to the eye. (2) Because the opening and closing angle of the existing product is large, the bending direction of the product cannot be controlled when the product is bent, and the coil is extruded and pulled easily. (3) The coil is in closed type, and the dislocation easily takes place in the closed department of shell, further influences the closure of inside coil, further influences measurement accuracy.

Detailed Description

Fig. 1 to 5 are preferred embodiments of the present invention, and the present invention will be further explained with reference to fig. 1 to 5.

As shown in fig. 1, an openable flexible rogowski coil includes a housing and a coil 10 disposed in the housing. The shell comprises first shell 1 and second shell 6, and first shell 1 and second shell 6 are semicircle form, and first shell 1 and 6 one end of second shell are articulated, and the other end forms the opening, and first shell 1 and second shell 6 use articulated department as the axle when rotating, and the open end is opened or is closed thereupon. The first and second housings 1 and 6 are closed to form a wire passing hole 4 for passing a cable at a central position.

The first housing 1 is provided with a guide plate 3 at the open end toward the second housing 6, and when closed, misalignment between the first housing 1 and the second housing 6 is effectively avoided by the guide plate 3. A lock catch 2 is arranged outside the open end for locking the first housing 1 and the second housing 6 after closing.

The first shell 1 and the second shell 6 respectively form an opening at the outer side of the hinged part, the two openings relatively form a limiting opening 8 of the shell, when the first shell 1 and the second shell 6 are opened, the limiting opening 8 is gradually reduced along with the gradual increase of the opening angle, and when the first shell 1 and the second shell 6 are contacted at the hinged part, the opening angle of the first shell 1 and the second shell 6 reaches the maximum.

Through setting up spacing mouthful 8 for the pin joint is located the inboard of shell, has injectd first shell 1 and second shell 6's opening angle simultaneously, avoids first shell 1 and second shell 6 opening too big, has further avoided first shell 1 and second shell 6 open-close type to coil 10's extrusion and has dragged, has prolonged coil 10's life. Meanwhile, the opening angles of the first shell 1 and the second shell 6 are limited through the limiting port 8, so that the coil 10 is not required to be arranged outside the shells at the hinged position, and the attractiveness of the product is improved.

As shown in fig. 2 to 3, the first housing 1 and the second housing 6 are respectively formed by fastening two housing units with symmetrical structures, a plurality of fixing holes 5 are respectively formed in the side portions of the first housing 1 and the second housing 6, and the housing units, which are butted with each other, of the first housing 1 and the second housing 6 are fixed by fixing objects (such as bolts and screws) placed in the fixing holes 5.

Two shell monomers of the first shell 1 and the second shell 6 are buckled to form cavities in the first shell 1 and the second shell 6 respectively, after the first shell 1 and the second shell 6 are closed, the cavities in the first shell 1 and the second shell 6 are butted simultaneously to form a containing cavity 9, and the coil 10 is placed in the containing cavity 9. After the coil 10 is placed in the accommodating chamber 9, epoxy resin is poured into the cavities in the first and second housings 1 and 6, respectively, and the coil 10 is cured in the accommodating chamber 9.

Referring to fig. 4 to 5, the guide plate 3 is disposed at an opening end of the first housing 1, a hinge plate 7 is disposed at the other end of the first housing 1, and a rotation shaft 11 is disposed on an inner surface of the hinge plate 7. The outer end face of each of the two single second housings 6 corresponding to the guide plate 3 is provided with a guide groove 13 corresponding to the guide plate 3, the end opening corresponding to the rotating shaft 11 is also provided with a hinged plate 7, and the hinged plate 7 is provided with a rotating shaft hole 12 corresponding to the rotating shaft 11. After the two single bodies of the second shell 6 are buckled and fixed, when the first shell 1 is formed, the rotating shafts 11 arranged at the end parts of the two single bodies of the first shell 1 are respectively arranged in the corresponding rotating shaft holes 12, and meanwhile, the hinged plates 7 at the end parts of the first shell 1 wrap the hinged plates 7 at the end parts of the second shell 6 from two sides to shield the rotating shafts 11 and the rotating shaft holes 12. While the first housing 1 and the second housing 6 are fixed while the two single bodies of the first housing 1 are fixed through the fixing holes 5.

While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention. However, any simple modification, equivalent change and modification made to the above embodiments according to the technical substance of the present invention still belong to the protection scope of the technical solution of the present invention.
