Description

Technical Field

[0001] The invention relates to the field of high-voltage power transmission line hardware, and in particular to a magnetic signal monitoring device and method for the shedding and damage of a spacer bar, wire clamp and rubber tile. Background Art

[0002] At present, due to the increase of voltage level and transmission current, split conductors are often needed for power transmission on transmission lines. In order to ensure the electrical performance and distance between the split conductors, a spacer bar needs to be installed at a certain distance. The spacer bar holds each split conductor through a wire clamp.

[0003] Transmission lines are in vibration areas, and there are often insufficient measures to monitor the status of rubber tiles with spacer bars. With large temperature differences between seasons and long-term use, rubber tiles are prone to aging, wear, and insufficient grip, resulting in falling off or damage.

[0004] In addition, there are also many cases where the rubber tile loses its fixed support and falls due to damage to the aluminum alloy shell of the wire clamp. Such accidents cause the conductor and the metal rigid friction of the wire clamp shell to be damaged. And after the accident, it is very easy to have a chain reaction, causing serious sub-span oscillation, resulting in failure of the spacer damping and wear of the wire, resulting in power outage of the line, and the wire and spacer need to be replaced and repaired. Summary of the invention

[0005] The purpose of the present invention is to provide a magnetic signal monitoring device and method for the detachment and damage of the spacer bar wire clamp rubber tile in order to solve the problem that the spacer bar of the transmission line is damaged due to the inability to monitor abnormal conditions such as the detachment and damage of the spacer bar rubber tile.

[0006] The technical solution adopted by the present invention is as follows:

[0007] A buckle trigger structure of a spacer bar decoupling clamp comprises a magnetic excitation device arranged in a clamp rubber tile and a magnetic field sensing module arranged on the clamp body. The magnetic field sensing module is used to detect the displacement change of the magnetic excitation device and send a trigger signal.

[0008] Preferably, the rubber tiles are arranged on the body and the gland of the wire clamp.

[0009] The present invention also provides a magnetic signal monitoring device for the detachment and damage of the rubber tile of the spacer bar wire clamp, comprising a wire clamp alloy cover, a wire clamp alloy body, a rotating shaft, a rubber tile, a magnetic excitation device, a magnetic field sensing module, a main control module, a power module and a communication module; the wire clamp alloy cover and the wire clamp alloy body are hinged through the rotating shaft, the rubber tile is respectively arranged on the inner side of the alloy cover and the alloy body, and the magnetic excitation device is embedded in the rubber tile through the pressing of the wire clamp alloy cover and the wire clamp alloy body.

[0010] Preferably, the magnetic excitation device includes a first magnetic excitation body and a second magnetic excitation body, the first magnetic excitation body is arranged in the rubber shoe of the wire clamp alloy cover, and the second magnetic excitation body is arranged in the rubber shoe of the wire clamp alloy body.

[0011] Preferably, the cross-sectional shape of the rubber tile is matched with the shape of the wire.

[0012] Preferably, the second magnetic exciter is arranged on the end of the rubber shoe on the wire clamp alloy body away from the rotating shaft, and the first magnetic exciter is arranged on the first end of the wire clamp alloy cover close to the rotating shaft; when the wire is fixed, the wire clamp alloy cover moves in a circle around the rotating shaft.

[0013] Preferably, the magnetic field sensing module, main control module, power supply module and communication module are all arranged in the wire clamp alloy body, the main control module is electrically connected to the communication module and the magnetic induction module, and the power supply module is electrically connected to the main control module, the communication module and the magnetic induction module respectively.

[0014] Preferably, the magnetic field sensing module is used to detect magnetic signals of the first magnetic exciter and / or the second magnetic exciter.

[0015] Preferably, the power supply module provides power for the entire device, and the main control module is used to receive the communication signal generated by the magnetic induction module. After receiving the signal, the main control module transmits the signal to the communication module and communicates with the outside world through the communication module.

[0016] The present invention also provides a method for monitoring the release of a spacer bar clamp and the state of a rubber tile, comprising the following steps:

[0017] Step 1: Integrate the magnetic excitation device with the rubber tile of the spacer wire clamp, and integrate the magnetic field sensing module with the spacer wire clamp; the magnetic field sensing module is respectively connected to the magnetic excitation device signal;

[0018] Step 2: When the spacer wire clamp is closed normally, the rubber tile does not move on the spacer wire clamp, and the magnetic field sensing module senses the magnetic field signal of the magnetic excitation device fixed on the rubber tile; when the rubber tile of the wire clamp is disengaged or damaged due to a fault, the magnetic excitation device is displaced, and the magnetic field sensing module built into the spacer wire clamp can trigger a signal. The trigger signal is received and collected by the main control module and transmitted to the remote monitoring system through the communication module, so as to warn the opening and closing status of the spacer;

[0019] Step 3: When the magnetic field sensing module senses the magnetic field signal of the magnetic excitation device on the rubber tile, it changes from a receiving state to a lost state, that is, the rubber tile is damaged or the rubber tile falls off. At this time, the magnetic field sensing module sends the signal loss state to the main control module. The main control module receives the loss signal and transmits it to the remote monitoring system through the communication module to warn the status of the rubber tile.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] (1) The present invention is provided with a magnetic field sensing module and a magnetic excitation device. The magnetic field signals emitted by the first magnetic excitation body and the second magnetic excitation body are captured by the magnetic field sensing module. When the wire clamp alloy cover and the wire clamp alloy body are opened and closed, the first magnetic excitation body and the magnetic field sensing module are relatively displaced, and the resulting magnetic field changes are captured by the magnetic field sensing module. The first magnetic excitation body and the magnetic field sensing module can be used to monitor whether the spacer bar is disengaged. If the signals of the first magnetic excitation body and / or the second magnetic excitation body cannot be captured by the magnetic field sensing module, it means that the rubber tile has fallen off or is damaged, or the wire clamp has been disengaged, etc., and the rubber tile needs to be replaced or maintained in time, thereby ensuring the safety of the wire and the spacer bar and reducing the occurrence of damage caused by the rigid friction between the wire and the metal of the wire clamp shell.

[0029] The present invention provides a trigger structure for a spacer rod decoupling clamp, comprising a magnetic excitation device 5 arranged in a clamp rubber shoe 4, and a magnetic field sensing module 6 arranged on the clamp body. The magnetic field sensing module 6 is used to detect the displacement change of the magnetic excitation device 5 and send a trigger signal.

[0030] The rubber shoe 4 is arranged on the body and the gland of the wire clamp. When the rubber shoe 4 of the wire clamp works abnormally and is tripped, the magnetic excitation device 5 is out of the monitoring range of the magnetic field sensing module 6. The magnetic field sensing module 6 generates a trigger signal. This model will start the main control module 7 to send an early warning message.

[0031] Example 2

[0032] like Figure 1 As shown, a magnetic signal monitoring device for the detachment or damage of a rubber tile 4 of a spacer bar wire clamp comprises a wire clamp alloy gland 1, a wire clamp alloy body 2, a rotating shaft 3, a rubber tile 4, a magnetic excitation device 5, a magnetic field sensing module 6, a main control module 7, a power module 8 and a communication module 9; the wire clamp alloy gland 1 and the wire clamp alloy body 2 are hinged through the rotating shaft 3, and the rubber tile 4 is respectively arranged on the inner side of the alloy gland 1 and the alloy body, and the wire is fixed in the cavity formed by the wire clamp alloy gland 1 and the wire clamp alloy body 2 through the pressing of the wire clamp alloy gland 1 and the wire clamp alloy body 2.

[0033] The magnetic excitation device 5 is embedded in the rubber tile 4, and the magnetic excitation device 5 includes a first magnetic excitation body 51 and a second magnetic excitation body 52. ​​The first magnetic excitation body 51 is arranged in the rubber tile 4 of the wire clamp alloy gland 1, and the second magnetic excitation body 52 is arranged in the rubber tile 4 of the wire clamp alloy body 2;

[0034] The rubber shoe 4 is configured as an arc-shaped structure, and the upper and lower rubber shoes 4 are used to tightly contact and fix the wires.

[0035] The second magnetic exciter 52 is arranged on the end of the rubber shoe 4 on the wire clamp alloy body 2 away from the rotating shaft 3, and the first magnetic exciter 51 is arranged on the first end of the wire clamp alloy cover 1 close to the rotating shaft 3; when fixing the wire, the wire clamp alloy cover 1 moves in a circular motion around the rotating shaft 3.

[0036] The magnetic field sensing module 6 is arranged on the wire clamp alloy body 2, and the magnetic field sensing module 6 is arranged at the rear side of the second magnetic excitation body 52. ​​The magnetic field signals emitted by the first magnetic excitation body 51 and the second magnetic excitation body 52 are captured by the magnetic field sensing module 6. When the wire clamp alloy gland 1 and the wire clamp alloy body 2 are opened and closed, the first magnetic excitation body 51 and the magnetic field sensing module 6 are relatively displaced, and the generated magnetic field changes are captured by the magnetic field sensing module 6. Whether the spacer bar is disengaged can be monitored through the first magnetic excitation body 51 and the magnetic field sensing module 6.

[0037] If the signals of the first magnetic exciter 51 and / or the second magnetic exciter 52 cannot be captured by the magnetic field sensing module 6, it means that the rubber tile 4 has fallen off or been damaged, and the rubber tile 4 needs to be replaced or maintained in time to ensure the safety of the conductors and spacer rods and reduce the occurrence of damage caused by rigid friction between the conductors and the metal of the wire clamp housing.

[0038] Based on the above structure, the magnetic excitation device 5 is an element that emits magnetic field excitation, such as a permanent magnet or a soft magnet, which is a good conductor that can spontaneously generate a magnetic field signal or a magnetic field emitted by a cable, and is built into the rubber tile 4; it emits a magnetic field signal to the magnetic field sensing module 6;

[0039] The magnetic field sensing module 6 is used to monitor the state of the wire clamp. When the wire clamp rubber tile 4 falls off, the magnetic field sensing module 6 triggers a tripping signal.

[0042] Through the overall device, abnormal conditions such as damage and falling off of the wire clamp rubber tile 4 can be detected in real time, and the tripping of the spacer rod can be monitored to ensure the safe and efficient operation of the spacer rod, and when a fault occurs, it can be known and handled in time, thereby improving the overall safety performance of the transmission line.

[0043] Based on the above structure, the power module 8 provides power to the main control module 7 and the communication module by induction self-powering;

[0044] The main control module 7 is used to analyze and process the trigger signals generated by the magnetic excitation device 5 and the magnetic field sensing module 6. After detecting the trigger signal, the main control module 7 generates a trigger report according to the instruction requirements.

[0045] The communication module is used for the communication transmission of the trigger report. When there is a trigger report, the communication module will transmit the trigger report to the monitoring system according to the specified communication method and address, so that the outside world can know the safety status of the spacer in real time, accurately and efficiently.

[0046] In addition to the function of clamping the wire itself, the aluminum alloy body of the spacer wire clamp is also used to place and protect the magnetic field sensing module 6, the main control module 7, the power module 8 and the communication module to ensure that they can operate in the complex electromagnetic environment, climatic environment and mechanical environment of the transmission line.

[0047] Example 3

[0048] The present invention also provides a method for monitoring the state of a spacer rod and a rubber tile 4, which comprises the following steps:

[0049] Step 1: Integrate the magnetic excitation device 5 with the rubber tile 4 of the spacer wire clamp, and integrate the magnetic field sensing module 6 with the spacer wire clamp; the magnetic field sensing module 6 is respectively connected to the magnetic excitation device 5 by signal;

[0050] Step 2: When the spacer wire clamp is closed normally, the rubber tile 4 does not move on the spacer wire clamp, and the magnetic field sensing module 6 senses the magnetic field signal of the magnetic excitation device 5 fixed on the rubber tile 4; when the rubber tile 4 of the wire clamp is disengaged or damaged due to a fault, the magnetic excitation device 5 is displaced, and the magnetic field sensing module 6 built into the spacer wire clamp can trigger a signal, and the trigger signal is received and collected by the main control module and transmitted to the remote monitoring system through the communication module 9, so as to give an early warning of the opening and closing state of the spacer;

[0051] Step three: When the magnetic field sensing module 6 senses the magnetic field signal of the magnetic excitation device 5 on the rubber tile 4, it changes from a receiving state to a lost state, that is, the rubber tile 4 is damaged or the rubber tile 4 falls off. At this time, the magnetic field sensing module 6 sends the signal loss state to the main control module. The main control module receives the loss signal and transmits it to the remote monitoring system through the communication module 9 to warn the status of the rubber tile 4.
