End effector for automatically disconnecting power line connecting plate

Abstract

The invention belongs to the technical field of power safety, and particularly relates to an end effector for automatically disconnecting a power line connecting plate. According to the effector, a mechanical arm is arranged on a busbar, and a position is adjusted through the linkage among pneumatic push rods, guide rail sliding blocks and servo motors, so that sleeves and bolts of the connectingplate are aligned accurately, and the sleeves can conveniently disassemble and assemble the bolts of the connecting plate. The effector can fix the disconnecting switch connecting plate and can be quickly and reliably butt-jointed with the bolts, so that a larger output torque is provide, a bolt smashing function is realized, and the bolts are disassembled and assembled.

Description

technical field [0001] The invention belongs to the technical field of electric power safety, in particular to an end effector for automatically disconnecting and connecting a power line connecting plate. Background technique [0002] There are many isolating switch connecting boards distributed on the 110kv high-voltage line of the substation. The isolating switch connecting boards are the connectors for the high-voltage lines to be shunted to various cities and towns. Since the isolating switch connecting boards are exposed outdoors all the year round, they are very vulnerable to environmental and geographical factors. influences. Some factors such as snowfall, blowing vibration and other factors will cause the bus bar to vibrate, which will lead to the loosening of the bolts of the connecting plate of the disconnector, and the contact surface will increase in resistance due to poor contact. Once the resistance increases, the temperature of the connecting plate will increa...

AI Technical Summary

Problems solved by technology

Some factors such as snowfall, blowing vibration and other factors will cause the bus bar to vibrate, which will lead to the loosening of the bolts of the connecting plate of the disconnector, and the contact surface will increase in resistance due to poor contact. Once the resistance increases, the temperature of the connecting plate will increase with the As the temperature rises, the oxidation of the connection board will be strengthened. As the temperature continues to increase, the connection board will be burned and a disconnection accident will occur. The area has caused huge economic losses

[0003] Due to the need to replace the bad connecting plate and bolts after a disconnection accident, if the current of the busbar is cut off and then disconnected, all areas powered by the busbar will be cut off, and the resulting economic losses are unimaginable; Therefore, at present, the disconnection is carried out by manual live work at high altitude, but this kind of defect is mainly caused by manual work at low potential or equipotential live work, but due to the limitation of live work distance, it is difficult for the operator to move, resulting in the failure of the bolts to tighten The torque fails to meet the requirements, and even the wrench socket cannot cover the bolts and cannot be tightened

Moreover, the equipotential live work needs to be approved by the dispatching department, and there is a long approval process, which makes it difficult to tighten loose bolts in time
