Description

Technical Field

[0001] The present application relates to the technical field of protection for live working on power transmission lines, and in particular to a detector for the on-off state of a shunt conductor connector and a detection method. Background Art

[0002] During the maintenance and repair work of high voltage (AC 110kV ~ 1000kV, DC ±125kV ~ ±1100kV) transmission lines, operators must wear shielding clothing. It uses the Ferrari cage principle to form equipotential shielding surfaces on various parts of the outer surface of the human body in the high-voltage electric field, thereby protecting the human body from the harm of high-voltage electric fields and electromagnetic waves. The joints of the shielding suit's clothes, pants, gloves, socks and other parts are equipped with metal soft ribbon electric working shielding suit shunt wires, which serve as the main current path in the clothes. After wearing the shielding suit, the live working shielding suit shunt wire connectors need to be connected to each other through the live working shielding suit shunt wire connectors, so that the various parts of the shielding suit are connected as a whole, thereby achieving the effect of equalizing pressure and shunting.

[0003] The shunt conductor connector of the live working shielding suit is composed of a left wiring terminal, a right wiring terminal, a connection cap, and a clamping spring. The left wiring terminal and the right wiring terminal are kept in contact with each other through the compression of the clamping spring, the fixing of the stop groove and the bayonet pin, so as to achieve electrical connection between the various parts of the shielding suit. However, since the internal clamping spring of the shunt conductor connector of the live working shielding suit is prone to fatigue deformation and its elasticity is weakened, and the connection part with the shunt conductor of the live working shielding suit is a rigid connection, the movements of the workers in the process of climbing the pole tower will naturally cause the shunt connection line to stretch and contract, causing the connectors between the various parts of the shielding suit to twist repeatedly, causing the contact between the left wiring terminal and the right wiring terminal to loosen or even disconnect as a whole, affecting the conduction performance of the current in the shielding suit. The disconnection of the shunt conductor connector of the live working shielding suit is not easy to detect, resulting in arc discharge between different parts of the shielding suit during operation and entry and exit, which can burn the workers and easily cause safety accidents.

[0004] There are two solutions to this problem in the existing technology. Chinese patent CN210640395U relates to a shunt wire connector for live working shielding suits, which is designed to be more solid and reliable, but it is usually difficult to balance firmness and easy disassembly. The shunt wire connector for live working shielding suits may be less likely to fall off if it adopts a more complex structural design, but it will also be more difficult and time-consuming for operators to wear and disassemble, reducing the operating efficiency; in addition, once the shunt wire connector for live working shielding suits of this structure is disconnected during the operation, it will not be able to effectively warn the operator.

[0005] Chinese patent CN113142702A relates to a shielding suit for live working on overhead transmission lines. By designing a large loop shielding suit shunt wire path for live working, the on-off state of the shielding suit shunt wire connector for live working is detected by resistance measurement. However, this solution requires rewiring of the shielding suit shunt wires for live working inside the shielding suit to improve the accuracy of small resistance measurement, and this solution can only detect the two states of connection and disconnection of the shielding suit as a whole, which is not enough to identify the disconnection position of the shielding suit shunt wire connector for live working inside the shielding suit, and cannot timely feedback to the operator the location information of the shunt wire connector for live working shielding suit that needs to be urgently handled.

There are two circular openings on the inner wall of the annular clamping mechanism, and the two metal contacts of the contact rebound protection mechanism can extend and retract from the corresponding two circular openings. The two metal contacts can be in direct electrical contact with the two terminals of the shunt wire connector to be tested during the monitoring process. When it is detected that the two terminals of the shunt wire connector are disconnected, the signal processing module sends a retraction instruction to the contact rebound protection mechanism to control the electromagnet to retract the two metal contacts in the direction close to the electromagnet.

[0036] A method for detecting an on / off state of a shunt wire connector, the method comprising: Obtaining on / off status signals between shunt wires of live working shielding clothing; the on / off status signals include: an on / off status signal between the left sleeve of the shielding clothing top and the left glove, an on / off status signal between the right sleeve of the shielding clothing top and the right glove, an on / off status signal between the left hem of the shielding clothing top and the left waistband, an on / off status signal between the right hem of the shielding clothing top and the right waistband, an on / off status signal between the left trouser leg of the shielding clothing and the left sock, and an on / off status signal between the right trouser leg of the shielding clothing and the right sock; Process each on / off status signal to generate an alarm signal; The on-off status detector of the shunt wire connector corresponding to the live working shielding suit is controlled by the alarm signal to send out an alarm, thereby realizing the on-off early warning of the shunt wire of the live working shielding suit.

[0037] The present application provides an embodiment as follows: the provided live working shielding suit shunt wire connector on-off state detector is a distributed detection device. On a set of split live working shielding suit, a total of six shunt wire connector on-off state detectors are arranged, respectively located at two wrists, two waists, and two ankles. Each shunt wire connector on-off state detector clamps the shunt wire connector at the location through an annular clamping mechanism.

[0038] During the specific implementation, first check whether the live shielding suit is intact, confirm that all conductive connectors and seams are not damaged, and ensure that the shielding efficiency of the shielding suit meets the standards. Wear the shielding suit in the correct order, and ensure that the top, pants, hat, gloves and shoes are correctly connected to form a complete shielding system. Connect the on-off state detector of the shunt wire connector of the present invention to each shunt wire connector of the shielding suit. Specifically, rotate the two terminals of the shunt wire connector, and under the action of the compression spring, complete the electrical connection and fixation of the left wiring terminal and the right wiring terminal through the cooperation of the stop groove and the bayonet pin, and put the opening and closing ring buckle on the on-off state detector on the two terminals, and apply force to insert the buckle connector into the buckle seat to ensure a firm connection. During the operation, continue to pay attention to the buzzing alarm of the on-off state detector. Once there is an abnormal situation, take corresponding measures immediately and reconnect the shunt wire connector at the corresponding position. After the operation is completed, check the status of the shielding suit and the monitoring device again to ensure that there is no damage. Apply force to remove the buckle joint of the opening and closing ring buckle on the on-off status detector from the buckle socket, remove the on-off status detector of each shunt wire connector on the shielding suit, and use a magnetic charger to charge the device. After it is fully charged, keep it properly for next use.

[0039] Working principle: Live working shielding suit shunt wire connector on-off status detector The two metal contacts of the contact rebound protection mechanism are electrically connected to the left and right end surfaces of the shunt wire connector at the location. After the shunt wire connector is inserted into the annular clamping mechanism, the electromagnet is triggered when power is turned on, which presses the contact plate to move outward, presses the spring, and drives the contact to move outward until the two metal contacts extend to contact the shunt wire connector, at which time a local conduction loop is formed with the connector on-off state judgment module. When the left and right ends of the shunt wire connector are disconnected, the conduction loop becomes an open circuit state, which can be quickly identified by the connector on-off state judgment module of the shunt wire connector on-off state detector, thereby sending the open circuit signal to the signal processing module, and the signal processing module controls the alarm module to emit a buzzing alarm sound, assisting the operator to quickly reconnect the disconnected terminals to avoid burns to the operator due to arc discharge between different parts of the shielding suit. At the same time, the detector controls the electromagnet of the contact rebound protection mechanism to cut off the power, the electromagnet resets and retracts, the spring assists in resetting, the contact plate returns, and the two metal contacts shrink toward the inner wall of the annular clamping groove of the annular clamping structure, disconnecting the electrical connection between the shunt wire connector on-off status detector and the two terminals of the shielding suit shunt wire connector, avoiding its internal resistance from being connected in series into the shielding suit, thereby affecting the conductive performance of the shielding suit.

[0041] The above are only exemplary embodiments of the present disclosure and cannot be used to limit the scope of the present disclosure. That is, any equivalent changes and modifications made according to the teachings of the present disclosure are still within the scope of the present disclosure.
