[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a substation equipment such as a gas insulated switchgear or a transformer, in which electric equipment is compactly housed, and in particular, a substation diagnosis suitable for checking and monitoring the reliability of the housing equipment. Regarding the device.

2. Description of the Related Art In recent years, due to the need to strengthen substation facilities accompanying the soaring land and the increase in power supply in urban areas, SF6 gas, which has excellent insulation and arc extinguishing properties, has been used to
A so-called gas-insulated switchgear has been widely used, in which transformers such as circuit breakers are housed in a sealed container and the environment resistance and the installation volume per KV · A are made compact.

This type of gas-insulated switchgear has various advantages such as compactness and reduction of the exposed charging part of the grounding tank, but on the other hand, maintenance diagnosis is difficult due to higher performance, maintenance and repair work time is increased, etc. If an abnormality occurs inside the container, there is a drawback that its reliability is significantly reduced.

Further, in recent years, the dependence of society on electric power has become higher and higher, and with the spread of computers, which are particularly sensitive to voltage fluctuations, there is a demand for higher electric power quality. For this reason, a substation diagnosis device is applied which is capable of confirming the reliability that the movable operating states of the gas insulated switchgear, the transformer and the like are normal and enabling early detection and monitoring when an abnormality occurs.

An outline of such a transformer diagnosing device will be described by taking a gas insulated switchgear as an example. That is, FIG.
As shown in, the sensor 1 attached to the device body detects the gas pressure, the partial discharge charge amount, and the like of the substation device. The signal from the sensor 1 is sent to each sensor receiver 4 provided in the on-site monitoring boards 3a and 3b via a transmission line 2 formed of an electric wire or an optical fiber cable. Each sensor 1
After being processed in the transmission device 5, the data from is transmitted to the main building board 7 via the transmission path 6. An optical fiber is mainly used as the transmission path 6 in consideration of noise resistance.

A computer 8 is connected to the main building board 7, and each measurement data is displayed on the display 9 and stored in the computer 8 and output to the printer 10 when necessary.

When a control computer is applied, control and monitoring are often separated and operated only for monitoring. Therefore, there is a problem that a large modification and a long down time of the substation diagnosis device are required.

Since the application of the control computer has many problems as described above, a general-purpose computer is usually applied to the substation diagnosing device.

Therefore, for a substation of the low voltage class, even if an attempt is made to apply the substation diagnosis device, the ratio of the substation diagnosis device to the total cost becomes very large, and thus the application is extremely difficult.

In addition to any of the above effects, since data can be input without passing through the signal detecting means, it is possible to provide a substation diagnosing device that can easily apply a measuring instrument such as a tester that cannot output a measurement result.

Further, according to the invention of claim 7, the general-purpose computer according to any one of claims 1 to 6 refers to the maintenance information storage means based on the identification information when the identification information is input, and the identification information is identified. Since the maintenance support information corresponding to the above is output, in addition to the effect according to any one of claims 1 to 6, it is possible to support maintenance of the substation equipment and support for the maintenance, and thus, the substation equipment diagnostic apparatus that can improve usability Can be provided.

According to the invention of claim 8, claim 1
When the general-purpose computer according to claim 7 inputs the identification information, the general-purpose computer refers to the accident-time information storage means based on the identification information and outputs the accident-response support information corresponding to the identification information. In addition to the effect of any one of claims 7 to 7, since it is possible to support the response at the time of an accident in the event of an unexpected accident, it is possible to provide a substation diagnostic device that can improve safety.

Further, according to the invention of claim 9, the general-purpose computer according to any one of claims 1 to 8 inputs the identification information and the drawing identification information, and based on the both identification information, the drawing information storage means. Since the drawing information corresponding to both identification information is output with reference to the above, it is possible to provide the transformer diagnosing device capable of improving the manageability of the drawing information regarding the transformer in addition to the effect of any one of claims 1 to 8. .

Further, according to the invention of claim 10, as the general-purpose computer according to any one of claims 1 to 9, the identification information and the identification information of the signal detecting means are input, and based on the both identification information. Since the handling information corresponding to both identification information is output by referring to the handling information storage means, in addition to the effect of any one of claims 1 to 9, the handling information of the signal detection means can be retrieved, which improves usability. It is possible to provide an improved substation diagnostic device.
