The online detection device and the detection method disclosed by the invention have advantages that the pointing angles of the operating rods are conveniently adjusted, and convenience is brought for online horizontal-vertical detection of high-altitude power equipment with 360-degree rotation by maintainers.

Description

technical field [0001] The invention relates to the technical field of high-altitude power equipment detection equipment, in particular to an on-line detection device and detection method for sulfur hexafluoride gas of high-altitude circuit breakers. Background technique [0002] At present, in the power system, with the continuous expansion and improvement of the power grid, there are more and more projects such as infrastructure projects, technical renovation projects, equipment overhauls, etc., and the size of the civil foundation of the equipment changes greatly in the original drawings. On-site size review is required, but the substation equipment is high-altitude and high-voltage operating equipment. In order to ensure the safety of people and equipment, Article 13.1I of the "Electricity Safety Regulations" stipulates that it is strictly forbidden to use steel tapes, leather tapes, and Line ruler (those with metal wire) for measuring work. However, in actual work, the...

AI Technical Summary

Problems solved by technology

However, in actual work, there are many violations of this regulation, and steel tapes are used for on-site measurement, which brings great potential safety hazards.

At the same time, when testing high-altitude sulfur hexafluoride circuit breakers, some use the switching lever for testing, but the switching lever has great limitations. At the same time, a camera, sound detection equipment, and sulfur hexafluoride gas detection equipment are installed on the upper end of the operating rod, which greatly increases the weight of one end of the rod, and it is more difficult to operate without a scale.

For the detection of sulfur hexafluoride gas, it is necessary to hold the operating rod and align the gas detection equipment at one end of the operating rod with the circuit breaker for a long time to detect accurately, which is more time-consuming and laborious; such as measuring the height of a 10 kV bus bridge and the wall bushing The size of the outer frame, etc., and some of them must be measured for power failure, so as to reduce the reliability of power supply, increase the workload of operating personnel, etc., and for the acceptance of new lines, it is necessary to test the electrical connection to the ground and measure the strain-resistant drainage line pair on the live line To measure the distance of the tower body, the operator usually needs the person on the pole to carry the electroscope and the distance measuring pole at the same time, which is inconvenient to work, which increases the difficulty of the work virtually and reduces the work efficiency

Due to the existence of the above-mentioned reasons, it has brought great troubles to electric workers.

[0003] At the same time, the center of gravity of the existing 110kv and 220kv existing wires is too high when the wires are hung high. When using an insulating operating rod for live work on the transmission line, the operating rod is relatively long for 110kV and 220kV, especially for multi-circuit line towers on the same tower The cross arm is 3-5 meters long, the operating rod is long (5-10 meters in length), and the weight is heavy. During the suspension process of the ground wire operating rod, the position is often high or the angle is special, which makes the suspension very difficult.

The operator needs to control the height of the center of gravity, which often puts the operator in a difficult situation. When the operation lasts for a long time or the operation is not smooth, it is difficult for the operator to lift the operating lever to perform live work, and the arm is prone to fatigue and the probability of accidentally injuring the porcelain sleeve of the equipment. Very large, and the time of the ground wire hanging is much longer than the actual operation time

Once the porcelain sleeve is damaged, it needs to be replaced, and the replacement requires power outages, which is time-consuming and labor-intensive, which greatly affects the reliability of power supply
