Abstract

In the transformer wire clamp provided in the embodiment of the present application, a magnetic column is arranged in the cavity of the wire clamp body, and the magnetic column is located on the bottom cavity wall of the cavity. The two ends of the V-shaped spring piece are flexibly connected to the cavity wall on the side of the cavity, and the middle part of the V-shaped spring piece is adsorbed on the upper surface of the magnetic column, and the V-shaped spring piece is located below the wire pressing piece. When the temperature of the wire clamp body exceeds the temperature threshold, the high temperature will cause the magnetic column to demagnetize, and the V-shaped spring piece will return to its original state and move toward the direction of the wire pressing piece. Since the temperature detection module is arranged between the V-shaped spring piece and the wire pressing piece, the temperature of the wire pressing piece can be detected by the temperature detection module, so that a temperature alarm signal can be sent out.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] like Figure 1-Figure 2 As shown, the transformer wire clamp provided in the embodiment of the present application includes a wire clamp body 100, a wire pressing member 500, a magnetic column 600, a V-shaped spring piece 700 and a temperature detection module, wherein the wire clamp body 100 is a connecting device of the power system, the wire clamp body 100 is a hollow structure design, and a cavity 200 is provided in the wire clamp body 100. The upper surface and the side surface of the wire clamp body 100 are respectively provided with a wire pressing through hole 300 and a cable through hole 400, and the wire pressing through hole 300 and the cable through hole 400 are respectively connected to the cavity 200 of the wire clamp body 100.

[0027] The wire pressing member 500 passes through the wire pressing through hole and extends into the cavity 200 of the wire clamp body 100. The wire pressing member 500 may be a bolt structure. In actual use, the cable may be inserted into the cavity 200 through the cable through hole 400, and the wire pressing member 500 is used to fix the cable.

[0028] In the present embodiment, the magnetic column 600 is a magnetic column structure, and the magnetic column 600 is arranged on the bottom wall of the cavity 200. The V-shaped spring piece 700 is arranged in the cavity 200 and is flexibly connected to the side wall of the cavity 200. The V-shaped spring piece 700 is made of ferromagnetic material, so the V-shaped spring piece 700 will be adsorbed to the upper surface of the magnetic column 600. In addition, when the V-shaped spring piece 700 is in the adsorption state, the V-shaped spring piece 700 is located below the wire pressing piece 500 and has a certain distance from the wire pressing piece 500.

[0029] The temperature detection module is a device for detecting the internal temperature of the wire clamp body 100. The temperature detection module is located on the upper surface of the V-shaped spring piece 700. At the same time, the temperature detection module is located between the V-shaped spring piece 700 and the wire pressing piece 500. The temperature detection module is also connected to an external alarm device. Once it is found that the temperature of the wire clamp body 100 exceeds the temperature threshold, the temperature detection module will immediately control the alarm device to sound an alarm.

[0030] In the transformer wire clamp provided in the embodiment of the present application, a magnetic column 600 is arranged in the cavity 200 of the wire clamp body 100, and the magnetic column 600 is located on the bottom wall of the cavity 200, and the demagnetization temperature of the magnetic column 600 is adapted to the temperature threshold of the wire clamp body 100. Both ends of the V-shaped spring piece 700 are flexibly connected to the wall of the side of the cavity 200, and the middle part of the V-shaped spring piece 700 is adsorbed on the upper surface of the magnetic column 600, and the V-shaped spring piece 700 is located below the wire pressing piece 500.

[0031] When the temperature of the wire clamp body 100 exceeds the temperature threshold, the high temperature will cause the magnetic column 600 to demagnetize, and the V-shaped spring piece 700 will return to its original state and move toward the wire pressing piece 500. Since the temperature detection module is arranged between the V-shaped spring piece 700 and the wire pressing piece 500, the temperature of the wire pressing piece 500 can be detected by the temperature detection module, so that a temperature alarm signal can be sent out.

[0032] In some embodiments, the magnetic column 600 is located at the center of the cavity wall at the bottom of the cavity 200 , so that the magnetic column 600 can be adsorbed together with the middle of the V-shaped spring piece 700 .

[0033] In some embodiments, the upper surface of the wire clamp body 100 is provided with two wire pressing holes 300 , and each wire pressing hole 300 is provided with a wire pressing member 500 . Moreover, the wire pressing holes 300 and the wire pressing member 500 are both located above the V-shaped spring piece 700 .

[0034] Preferably, the two wire pressing holes 300 and the corresponding wire pressing members 500 are symmetrically distributed on the cavity wall at the bottom of the cavity 200 with the center point of the magnetic column 600 as the symmetrical point.
