Description

Technical Field

[0001] The present invention relates to the technical field of electric power fittings, and in particular to an intelligent anti-loosening high-voltage wire-clamping electric power fitting. Background Art

[0002] At present, the wire clamps of overhead power lines are used to fix conductors on insulator strings or hang lightning conductors on straight tower poles, and are also used to support transposed conductors on transposition poles and fix jumpers on tension and corner poles. Under normal operation or in the case of wire breakage of the line, the wire clamp should have sufficient gripping strength for the conductor to avoid insufficient safety distance from the crossing structure due to the conductor slipping out of the wire clamp after the adjacent span wire breaks.

[0003] Existing wire clamps mostly adopt bolt fastening connections. For high-altitude operations, the operation of rotating the nut multiple times to clamp the cable is laborious and time-consuming, and the nut is prone to loosen due to vibration.

[0004] The tubular busbar fixing wire clamp is used to fix the tubular busbar on the post insulator or on the post insulator with a bracket. In the prior art, the purpose of tightening or loosening is usually achieved by adjusting the clamping arm, that is, by adjusting the tightness of the bolt to achieve tightening or loosening. There is a hidden danger of loosening after long-term use of the adjusting bolt. Summary of the Invention

[0005] Based on the technical problems existing in the background art, the present invention proposes an intelligent anti-loosening high-voltage wire-clamping electric power fitting, which realizes double clamping protection for the wire clamp. Through real-time detection by a current sensor, the loosening problem of the wire clamp can be accurately determined, which is convenient for maintenance.

[0006] An intelligent anti-loosening high-voltage wire-clamping electric power fitting proposed by the present invention includes a wire clamp body. The wire clamp body is a circular ring body with an opening. Both ends of the opening of the circular ring body are provided with clamping arms. The two clamping arms are relatively parallel and symmetric. Threaded holes are opened on the clamping arms. The two clamping arms are fixedly connected by fastening bolts. An anti-loosening device is installed outside the two clamping arms. A current transformer and a signal transmitting module are installed inside the anti-loosening device. The anti-loosening device is also connected to a metal fixing band. The metal fixing band is electrically connected to the current transformer. An insulating filling material is provided inside the wire clamp body. The conductor passes through the wire clamp body and is placed at the central part of the insulating filling material.

[0007] Further, the anti-loosening device is a frame body, and the anti-loosening device completely covers the two clamping arms inside the frame body.

[0008] Further, the wire clamp body is an elastic circular ring body. The wire clamp body and the clamping arms contract and clamp the conductor under the tightened state of the fastening bolts.

[0009] Further, the anti-loosening device is connected to the metal fixing band through a fixed tightening device. The metal fixing band is installed on the peripheral surface of the clamp body. Rotating the fixed tightening device can loosen or tighten the metal fixing band, so that the metal fixing band is tightly installed on the peripheral surface of the clamp body.

[0010] Further, the current transformer is installed on the inner wall of the anti-loosening device and is electrically connected to the metal fixing band, using the metal fixing band as a current-carrying conductor.

[0011] Further, the signal transmitting module is electrically connected to the current transformer, collects the current status information data detected by the current transformer, and packs and sends the collected information data to the nearby receiving base station.

[0012] Further, the current transformer establishes information communication with the control system by wired or wireless means.

[0013] Further, it also includes a communication cable. The communication cable is laid synchronously with the wire. The communication cable passes through the clamp body and is electrically connected to the signal transmitting module.

[0014] The advantages of an intelligent anti-loosening high-voltage wire-clamping power fitting provided by the present invention are as follows: Under the fixing action of the existing clamping arms and fastening bolts of the clamp body, the present invention adds an anti-loosening device to achieve double protection for the stable installation of the clamp. The cooperation of the clamp body, clamping arms and fastening bolts realizes the first-level anti-loosening protection, and the connection and cooperation of the anti-loosening device and the metal fixing band realizes the second-level anti-loosening protection. The electrical connection and cooperation of the current transformer and the metal fixing band achieve the effect of real-time monitoring. When an external force causes the clamp to loosen or be damaged, the signal of the current detected by the current transformer can be transmitted to the control system in time, enabling timely repair and maintenance, not only improving safety protection but also facilitating repair and maintenance.
