Description

Technical Field

[0001] The invention relates to the field of high-voltage power transmission line hardware, and in particular to an electrical signal monitoring device and method for the shedding and damage of a spacer bar wire clamp 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 an electrical signal monitoring device and method for the detachment and damage of spacer bar wire clamp rubber tiles in order to solve the problem that abnormal conditions such as detachment and damage of spacer bar rubber tiles cannot be monitored, resulting in damage to the transmission line spacer bars.

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

[0007] A tripping trigger structure for a spacer rod decoupling clamp is characterized by comprising a connector plug arranged in a rubber tile of the clamp and a connector socket arranged on the rubber tile of the clamp body, wherein the connector plug and the connector socket are matched with each other.

[0008] Preferably, the rubber tiles are arranged on the body and the pressure cover of the wire clamp. When the rubber tiles of the wire clamp work abnormally and become disengaged, the connector socket is disengaged from the connector plug and the electrical circuit is disengaged. When the rubber tiles of the wire clamp work normally, the connector socket remains connected to the connector plug and the electrical circuit is normal.

[0009] The present invention provides an electrical signal monitoring device for the shedding and damage of a spacer bar wire clamp rubber tile, comprising a wire clamp alloy gland, a wire clamp alloy body, a rotating shaft, a rubber tile, a connector plug, a connector socket, a main control module, a power module and a communication module; the wire clamp alloy gland and the wire clamp alloy body are hinged through a rotating shaft, and the rubber tile is respectively arranged on the inner side surfaces of the alloy gland and the alloy body.

[0010] Preferably, the connector plug is embedded on one end of the wire clamp alloy gland rubber tile, and the connector socket is arranged on one end of the wire clamp alloy body rubber tile; the connector plug and the connector socket are matched and arranged.

[0011] Preferably, the rubber shoe is configured as an arc-shaped structure, and the wires are closely contacted and fixed by the upper and lower rubber shoes.

[0012] Preferably, the main control module, the power module and the communication module are all arranged in the wire clamp alloy body, the main control module is electrically connected to the communication module, the power module is electrically connected to the main control module and the communication module respectively; the main control module is connected to the connector plug and the connector socket respectively.

[0013] Preferably, the main control module is used to analyze and process the connector plug, the connector socket and the trigger generation signal. After monitoring the trigger signal, the main control module generates a trigger report according to the instruction requirements.

[0014] Preferably, the communication module is used for triggering the communication transmission of the report. When a report is triggered, the communication module transmits 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 rod in real time, accurately and efficiently.

[0015] The present invention provides a method for monitoring the release of a spacer rod and the state of a rubber tile, comprising the following steps:

[0016] Step 1: The connector socket is integrated with the housing of the spacer wire clamp to be tested and connected to the main control module, and the connector plug is integrated with the rubber tile of the spacer wire clamp; the main control module is used to receive the electrical signals generated by the connector socket and the connector plug;

[0017] Step 2: When the line clamp is closed normally, the rubber tile does not move on the line clamp, and the connector plug and the pins in the socket are connected to form a loop; when the rubber tile of the line clamp is removed or damaged due to a fault, the connector plug moves, so that the loop is disconnected and the signal is triggered;

[0018] Step 3: The trigger signal will be collected by the main control module and wirelessly transmitted to the remote monitoring system by the communication module to warn of the spacer rod failure.

[0019] Preferably, the rubber tiles are arranged on the body and the gland of the wire clamp.

[0030] The rubber tile 4 is arranged on the body and the pressure cover of the wire clamp. When the rubber tile 4 of the wire clamp works abnormally and is disengaged, the connector socket 6 is disconnected from the connector plug 5, and the electrical circuit is disconnected. When the rubber tile 4 of the wire clamp works normally, the connector socket 6 is connected to the connector plug 5, and the electrical circuit is normal.

[0033] The connector plug 5 is embedded on one end of the rubber tile 4 of the wire clamp alloy gland 1, and the connector socket 6 is arranged on one end of the rubber tile 4 of the wire clamp alloy body 2; the connector plug 5 and the connector socket 6 are matched and arranged.

[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] When fixing the wire, the wire clamp alloy gland 1 performs circular motion around the rotating shaft 3; when the wire clamp rubber tile 4 works normally, that is, the wire clamp alloy gland 1 is normally connected to the wire clamp alloy body 2 cover box, the connector socket 6 and the connector plug 5 remain connected, and the electrical circuit between the two is normal; when the wire clamp rubber tile 4 works abnormally and is tripped, the connector socket 6 is disconnected from the connector plug 5, and the electrical circuit between the two is disconnected, and the main control module 7 receives a tripping or continuous buttoning signal, and the opening and closing of the connector plug 5 and the connector socket 6 can monitor whether the spacer rod is tripped;

[0036] The main control module 7, the power module 8 and the communication module 9 are all arranged in the wire clamp alloy body 2, the main control module 7 is electrically connected to the communication module, and the power module 8 is electrically connected to the main control module 7 and the communication module 9 respectively; the main control module 7 is connected to the connector plug 5 and the connector socket 6 respectively;

[0037] The power module 8 provides power supply for the entire device. The main control module 7 is used to receive the communication signal generated by the connector plug 5 and the connector socket 6. After receiving the signal, the main control module 7 transmits the signal to the communication module and communicates with the outside world through the communication module 9.

[0038] 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.

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.

[0042] The aluminum alloy body of the spacer clamp not only clamps the wire, but is also used to place and protect the main control module 7, power module 8 and communication module, ensuring that they can operate in the complex electromagnetic environment, climatic environment and mechanical environment of the transmission line.

[0043] Under normal circumstances, the connector plug 5 built into the rubber tile 4 is connected to the pin inside the connector socket 6 built into the wire clamp alloy body 2, forming a loop with the wire connected to the main control module 7. When the rubber tile 4 of the spacer bar wire clamp is disengaged or damaged due to a fault, the connector plug 5 is disengaged from the connector socket 6 and a disconnection signal is generated. The signal is received and analyzed by the main control module 7, and a trigger message is generated, which is wirelessly transmitted to the remote monitoring system through the communication module.

[0047] Step 2: When the line clamp is closed normally, the rubber tile 4 does not move on the line clamp, and the connector plug 5 is connected with the pins in the socket to form a loop; when the rubber tile 4 of the line clamp is disengaged or damaged due to a fault, the connector plug 5 moves, so that the loop is disconnected and the signal is triggered;

[0048] Step 3: The trigger signal will be collected by the main control module 7 and wirelessly transmitted to the remote monitoring system by the communication module to warn of the spacer rod failure.
