断管理する装置に関するものである。[Detailed Description of the Invention] Purpose of the Invention (Field of Industrial Application) The present invention diagnoses and manages the opening/closing operation status (resistance) of a disconnector/grounding device used as one of power plants or substation equipment. It is related to the device.
（従来の技術）
一般に、発電所あるいは変電所設備の１つである断路器

は屋外に露出設置されている関係上、特に潤滑油塗布部
は塵埃が付着凝固したり、風雨によって１ｆｆｌ滑油が
流出、揮発したりして摩擦すなわち摺動抵抗が増大し、
この結果、断路器あるいは接地装置の開閉時には、不完

油を塗布している。(Prior Art) In general, in order to maintain good operation of the electrode part and mechanical part of a disconnector or grounding device, which is one of the facilities of a power plant or substation, the contact surface of a contact and the sliding of a mechanical part are Lubricating oil is applied to the bearings to reduce sliding resistance due to friction, but since the electrodes and mechanical parts of the disconnector or grounding device are exposed outdoors, the lubricating oil-applied parts are particularly dry. Friction, or sliding resistance, increases due to dust adhering and solidifying, or 1ffl lubricating oil leaking out and volatilizing due to wind and rain.
As a result, when opening/closing a disconnector or grounding device, incomplete closing, incomplete contact, or inability to open the circuit may occur. Therefore, in order to maintain good opening/closing operation, each part of the disconnector or grounding device should be inspected and cleaned once every three years, and the contact surfaces of the contacts and sliding bearings of the mechanical parts should be lubricated. Applying oil.
この定期点検は発電所あるいは変電所の停電を伴うとと

する目的で行なうので、開閉動作が良好なものまで点検
することになり不経済である。This periodic inspection not only involves a power outage at the power plant or substation and requires human resources, but also because the periodic inspection is performed for the purpose of maintaining good 1fl leap operation of the disconnector or ground B position. This is uneconomical as it requires inspection even if the opening/closing operation is good.
一方、断路器あるいは接地装置が悪環境下に設置されて

開閉動作不良となる問題がある。On the other hand, if the disconnector or grounding device is installed in a bad environment, the sliding resistance will increase within the regular inspection period of three years, and the opening/closing operation of the disconnector or grounding device will become defective before the inspection. In some cases, power outages are not possible due to power demand.
In some cases, the three-year inspection is postponed, resulting in problems with opening and closing operations.

る問題点を解決しようとしている。(Problems to be Solved by the Invention) The present invention periodically inspects and cleans each part of the conventional disconnector or grounding device. The problems with the method of applying lubricant are that it causes power outages at power plants or substations, increases human costs, is uneconomical as it requires inspecting things that don't need inspection, and disconnects before inspection. or the opening/closing operation of the equipment or grounding device is malfunctioning.
The project is trying to solve the problem of power outages being interrupted due to power demand and inspections being postponed.

できないことが分る。To explain this measurement result based on FIG. 4, the disconnector 1
It can be seen that the measured opening/closing time Tx of 0-1 is delayed by a certain time Δ compared to the normal opening/closing time TO. Furthermore, it can be seen that the opening/closing operation cannot be performed unless the measured opening/closing pressure curve LIIX is higher than the normal opening/closing pressure curve Lpc by Δp.

を未然に防止し点検の合理化を図ることができる。Furthermore, the measured opening/closing speed curve 1sx is the normal opening/closing speed curve 1
It can be seen that there is a delay of ΔS compared to sc. Then, by storing the measured switching time Tx, the measured switching pressure curve 1px, and the measured switching speed curve 1sx by the data processing device 29 each time a plurality of switching operations are performed for the same disconnector 10-1, the fifth A graph like the one shown in the figure can be displayed, and based on these measurement data, it is possible to predict when the measured switching time Tx will reach the limit switching time Tm, or to predict when the measured switching pressure curve px will reach the limit switching time. You can predict when the pressure curve L111II will be reached, and similarly, the measured opening/closing speed curve 1sx can be predicted as the limit opening/closing speed curve LSI1l.
Therefore, it is possible to predict the time when the disconnector 10-1 will reach the point where the disconnection switch 10-1 has deteriorated over time, and to determine the time when an inspection is required without having to perform periodic inspections. This makes it possible to prevent disconnector malfunctions and streamline inspections.

If the abnormal pressure exceeds l, it is possible to determine at what position, that is, at what opening/closing stroke, the abnormal pressure occurs in relation to the measured opening/closing speed curve 1sx, and in this way, the abnormal location of the disconnector can be discovered. In this way, pressure curve 1
By using px and the speed curve LSx in combination, it is possible to discover the abnormality of the disconnector, but this can also be roughly understood from the relationship with the opening/closing time Tx.
