Description

Technical Field

[0001] The invention belongs to the field of electrical maintenance, and in particular relates to a grounding wire device used for maintenance of outdoor electrical porcelain equipment in a switch station of a nuclear power plant. Background Art

[0002] The grounding wire is a safety device used to temporarily short-circuit and ground equipment that has been powered off. Its function is to prevent the equipment from suddenly receiving power or the induced voltage from adjacent high-voltage live equipment from causing harm to the human body when the high-voltage equipment is shut down for maintenance or other work is carried out. At the same time, it discharges the residual charge of the power-off equipment. During the maintenance of outdoor electrical porcelain equipment in nuclear power plants, there is a situation where multiple grounding wires are connected and used with the three phases separated due to insufficient grounding wire length.

[0003] The grounding wire should be a set of grounding wires consisting of grounding and short-circuit wires. Due to the lack of suitable three-phase combined grounding wires, workers often use multiple grounding wires in series to achieve grounding. Since most nuclear power plants are located at the seaside and have strong sea breezes, the connection points of multiple grounding wires will shake, resulting in poor contact or even disconnection of the connection points of multiple connected grounding wires. If there are live lines nearby, induced electricity may occur on the power outage line, and the grounding wire and the conductor may repeatedly arc and burn the conductor, causing the conductor to break, which seriously threatens the safety of operators when sudden situations such as lightning strikes and leakage occur.

[0004] In traditional technology, the installation and removal of ground wires for 500kV AC transmission lines is carried out by first hooking the bolt-type ground wire clamp on the conductor with an insulated operating rod, and then rotating the operating rod to drive the bolt-type wire clamp to clamp and open the conductor. However, the thread travel is very long, and it is very laborious and time-consuming to extend the hand outside the lifting vehicle to rotate the operating rod. The insulated operating rod of each phase conductor is long, heavy, and large in size, which is not easy to operate in the limited space of the tower frame and transmission conductor. It is also common that the thread is stuck and cannot be disassembled after the operating rod is stressed, affecting the smooth completion of the operation. In addition, the strong wind at the seaside and the direct sunlight outdoors during the day also have a certain impact on the efficiency of hanging ground wires. Summary of the invention

[0017] The beneficial technical effects of the present invention are:

[0018] 1. The present invention provides a grounding wire device for the maintenance of outdoor insulator equipment in a switch station of a nuclear power plant. When the terminal clamp is connected to the conductor, the locking block is located at the bottom of the terminal clamp. At this time, the movable plate will not be limited by the locking block, and the movable plate can be flipped. At this time, the wire can enter the interior of the terminal clamp and be located between the locking block and the movable block. Then, the drive motor can be remotely started through a PLC controller or a mobile phone. The drive motor drives the drive shaft to rotate. The drive shaft is threadedly connected to the locking block. Under the limitation of the partition plate, the locking block will move upward inside the terminal clamp, so that the wire can be clamped and fixed between the movable block. At the same time, the movable plate will be limited by the locking block and cannot be flipped, thereby achieving the effect of preventing the wire from falling off from the inside of the terminal clamp.

[0019] 2. The present invention provides a grounding wire device for the maintenance of outdoor electrical porcelain equipment in a nuclear power plant switch station. Through the setting of a detection mechanism, when the wiring clamp is not installed on the wire, the locking block will trigger the first trigger. At this time, the status can be displayed on the PLC controller. When the wiring clamp is installed on the wire, the locking block is separated from the first trigger. At the same time, the movable block drives the extrusion rod upward to trigger the second trigger. The PLC controller will also receive a signal. When the wiring clamp is loosened from the wire, the movable block and the extrusion rod will be separated from the second trigger under the action of gravity. At this time, the PLC controller will receive a signal, and then an alarm can be issued through the alarm, thereby achieving the effect of a loose alarm.

[0020] 3. The present invention provides a grounding wire device for the maintenance of outdoor electrical porcelain equipment in a switch station of a nuclear power plant. When the winding motor is started, the winding motor can drive the winding roller to rotate, and the winding roller can then wind up the grounding wire body into the interior of the control box. At the same time, the winding roller drives the transmission shaft to rotate through the transmission gear and the transmission belt, and the transmission shaft is threadedly connected to the mounting seat, and the mounting seat will make reciprocating motion on the transmission shaft, thereby driving the wire ring to guide the grounding wire body, so that the grounding wire body can be evenly wound up on the winding roller. Due to the electrical connection between the winding motor and the PLC controller, the grounding wire body is set with a nine-digit code number before hanging, and can be locked by the person in charge of the work after the installation is completed, the winding motor will be locked, and the grounding wire cannot be manually released and recovered before unlocking. At the same time, the working time can be regularly broadcast through the PLC controller, and a reminder will be given after the working time is over to prevent the grounding wire body from being forgotten and not recovered.

[0021] 4. The present invention provides a grounding wire device for the maintenance of outdoor electrical porcelain equipment in a nuclear power plant switch station. The device is provided with a power-off telescopic rod and a stop block. When the device loses power, the power-off telescopic rod will be driven, and the power-off telescopic rod will drive the stop block to move downward. The downward movement of the stop block will limit the movable plate. At this time, the movable plate cannot be flipped, and the wires cannot be loosened from the inside of the terminal clamp, thereby achieving the effect of still being clamped after power failure, avoiding the situation where the lower grounding clamp is loosened from the wire after power failure.

[0022] 5. The present invention provides a grounding wire device for the maintenance of outdoor electrical porcelain equipment in a nuclear power plant switch station. Through the setting of a locking mechanism, after the wiring clamp is set up, the take-up roller can be locked by the locking mechanism, so that the grounding wire body cannot be released or taken up on the take-up roller. The locking bolt is rotated and the locking bolt moves inside the locking groove, thereby applying a limiting force to the take-up roller, so that the take-up roller is locked and cannot rotate, thereby achieving the effect of being unable to release or take up the wire before unlocking.

[0041] The present invention provides a grounding wire device for maintenance of outdoor insulator equipment in a nuclear power plant switch station, and its working principle is as follows:

[0042] When the terminal clamp 2 is electrically connected to the conductor, the locking block 23 is located at the bottom of the terminal clamp 2. At this time, the movable plate 251 will not be limited by the locking block 23, and the movable plate 251 can be flipped. At this time, the wire can enter the interior of the terminal clamp 2 and be located between the locking block 23 and the movable block 24. Then, the drive motor 26 can be remotely started through the PLC controller 14 or the mobile phone. The drive motor 26 drives the drive shaft 261 to rotate. The drive shaft 261 is threadedly connected to the locking block 23. Under the limitation of the partition 262, the locking block 23 will move upward inside the terminal clamp 2, so that the wire can be clamped and fixed between the movable block 24. At the same time, the movable plate 251 will be limited by the locking block 23 and cannot be flipped, so that the wire cannot fall off from the inside of the terminal clamp 2.

[0043] Through the setting of the detection mechanism, when the wiring clamp 2 is not installed on the wire, the locking block 23 will trigger the first trigger 28, and the status can be displayed on the PLC controller 14 at this time. When the wiring clamp 2 is installed on the wire, the locking block 23 is separated from the first trigger 28, and the movable block 24 drives the extrusion rod 27 upward to trigger the second trigger 29, and the PLC controller 14 will also receive a signal. When the wiring clamp 2 is loosened from the wire, the movable block 24 and the extrusion rod 27 will be separated from the second trigger 29 under the action of gravity. At this time, the PLC controller 14 will receive a signal, and then an alarm can be issued through the alarm 16, thereby achieving the effect of loosening alarm;

[0044] The winding motor 43 is started, and the winding motor 43 can drive the winding roller 12 to rotate, and the winding roller 12 can then reel the grounding wire body 13 into the interior of the control box 1. At the same time, the winding roller 12 drives the transmission shaft 42 to rotate through the transmission gear 44 and the transmission belt 45, and the transmission shaft 42 is threadedly connected to the mounting seat 47, and the mounting seat 47 will reciprocate on the transmission shaft 42, thereby driving the wire ring 48 to guide the grounding wire body 13, so that the grounding wire body 13 can be evenly reeled on the winding roller 12. Since the winding motor 43 is electrically connected to the PLC controller 14, the grounding wire body 13 is set with a nine-digit code number before hanging, and can be locked by the person in charge of the work after the installation is completed, the winding motor 43 will be locked, and the grounding wire cannot be manually released before unlocking. At the same time, the working time can be broadcasted regularly through the PLC controller 14, and a reminder is given after the working time is over to prevent the grounding wire body 13 from being forgotten and not recovered.

[0045] When winding the wire, the grounding wire body 13 moves inside the cleaning sponge 521 and the cleaning ring 541, and the cleaning ring 541 and the cleaning sponge 521 clean the mud and water and other debris on the grounding wire body 13, ensuring that the grounding wire body 13 will not be corroded by mud and water when it is wound inside the grounding wire body 13.
