Switchgear with monitoring and diagnosis function for earthquake or vibration

The present invention relates to a switchgear, and more specifically, the efficiency of the maintenance and management of the switchgear by accurately measuring and providing information about the occurrence and the degree of vibration or earthquake that affects the switchgear and affects the switchgear. By accurately measuring and providing not only the occurrence of vibration or earthquake, but also the direction and intensity, it is possible to accurately determine the impact and damage on the switchboard. The present invention relates to a switchgear having a function of monitoring and diagnosing earthquake or vibration capable of accurately determining whether it is vibration.

In general, in the process of supplying the power generated by the power plant to the customer, it is necessary to step up or step down the voltage in several stages, and also to concentrate or distribute the power transmission power.

In addition to these roles, substations play an important role in protecting voltage variations and regulation, power concentration and distribution, power flow control, transmission and distribution lines and power installations in substations.

Electric power equipment is widely distributed and exposed to natural disasters, and it is not only easy to put the equipment at risk due to overload, but also the accident of the equipment itself is likely to occur. In preparation for such a situation, various protection devices are installed in substations to protect transmission and distribution lines and substations. In the event of a fault such as a short circuit or ground fault in various power equipments, a facility such as a circuit breaker is necessary to cut off the large current to protect the equipment. In addition, there is a need for a facility for monitoring a device such as a circuit breaker in the field to operate without failure, transmitting a control signal, and checking a history state.

Accordingly, a switchgear (system) is being operated to operate the monitoring, control, and measurement functions of the substation's field equipment by a communication method. The switchgear (system) means a water substation device such as a transformer, a switchgear, various safety switchgear and a measuring device for converting electric power received at high or low voltage into a voltage suitable for the type of load equipment, and a water substation room for storing them Commonly referred to as cubicles.

Since the switchgear is a facility in which various electrical-related configurations and wiring are made, vibration in the switchgear may cause not only the failure of these components, but also a fire due to an arc, and the like. Such damage can be expected much greater. However, the conventional switchgear does not include any measurement or monitoring function for earthquake or vibration that may affect the switchgear in the switchgear or at the point where the switchgear is installed.

Hereinafter, with reference to the accompanying drawings, preferred embodiments of the switchgear having a monitoring and diagnostic function for the earthquake or vibration according to the present invention. In the following description of the present invention, if it is determined that a detailed description of a known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted. Throughout the specification, when a part is said to "include" any component, which means that it may further include other components, except to exclude other components unless specifically stated otherwise, also described in the specification The terms "... unit", "... module" and the like refer to a unit for processing at least one function or operation, which may be implemented by hardware or software or a combination of hardware and software.

1 and the like, the switchgear having a monitoring and diagnostic function for earthquake or vibration according to an embodiment of the present invention, the excitation light source unit 10 for irradiating the excitation light 1 from one side of the switchgear; A reflection plate 30 reflecting the excitation light 1 irradiated from the excitation light source unit 10; A light receiving unit 20 which receives and reflects the excitation light 1 (referred to as “reflected light 2”) reflected by the reflector 30; And a measurement processing unit 50 for determining whether or not vibration or earthquake is generated in the distribution panel based on the information measured by the light receiving unit 20.

The excitation light source unit 10 is configured to irradiate the excitation light 1, and the monitoring and diagnostic function of the switchboard according to the present invention is made based on the path of light in the switchboard. . The light source may be a light source such as a short wavelength laser, LED, UV-LED, and the like. Meanwhile, in the present invention, the excitation light source unit 10 and / or the light receiving unit 20 are connected to the power distribution panel, and the reflector 30 to be described later may be formed separately from the power distribution panel and preferably connected to the ground. have. This will be described later.

The light receiving unit 20 is configured to receive and measure the excitation light 1, that is, the reflected light 2, reflected by the reflector 30, which will be described later. The data is sent to the measurement processing unit 50. As the light receiving unit 20, a photodiode or the like capable of receiving and measuring light may be used. As described above, the light receiving unit 20 is connected to the switchboard together with the excitation light source unit 10, the reflector 30 to be described later may be formed in a structure connected to the ground separately from the switchboard. have.

The reflective plate 30 is configured to be inclined at an angle so that the excitation light 1 irradiated from the excitation light source unit 10 is reflected and directed toward the light receiving unit 20. If the excitation light 1 and the reflected light are (2) when the optical paths overlap each other, it is difficult to accurately measure due to the interfering light, thereby causing an error in the accuracy of monitoring and diagnosis, and to prevent this, reflected light through the configuration of the reflector 30 By changing the optical path of (2), interference (collision) between the excitation light 1 and the reflected light 2 can be prevented. The reflective plate 30 preferably reflects the path of the reflected light 2 at an angle of about 10 to 30 degrees. In this case, as described above, unlike the excitation light source unit 10 and / or the light receiving unit 20, which is connected to the switchgear and moves like a shake of the switchgear, for example, the reflector 30 is connected to a ground separate from the switchboard. Since the structure is formed to be shaken together with the ground, it is possible to accurately detect the case where the switchgear only shakes and the case where the switchgear and the ground shakes together, it is possible to accurately measure whether the earthquake or vibration. On the other hand, the excitation light source unit 10 and the light receiving unit 20 is more preferably as shown in Figure 1, it is preferable to be installed in a structure connected to each other in the same direction for more accurate measurement.

The measurement processing unit 50 is configured to determine whether or not the vibration or earthquake in the switchgear (or at the point where the switchgear is located) based on the information measured by the light receiving unit 20, specifically for this purpose Through 20, the excitation light 1 (more accurately, the reflected light 2 reflected by the reflector 30) is measured based on the information of repeating the measured and unmeasured state of vibration to earthquake in the switchboard. It may include a generation measurement module 510 for determining whether or not occurrence.

That is, the generation measurement module 510 continuously detects the reflected light 2 through the photodiode of the light receiving unit 20 while the excitation light 1 is continuously irradiated through the excitation light source unit 10. If the reflected light 2 is not sensed out of the photodiode of the light receiving unit 20 or if the reflected light 2 is not detected by the light receiving unit 20 while shaking, the excitation light source unit 10 may be caused by vibration or earthquake. And / or the light receiving unit 20 is determined by the shaking and determines whether the vibration or earthquake in the switchgear.

Meanwhile, in another embodiment of the present invention, the light receiving unit 20 may include a plurality of photodiodes. For example, as shown in FIG. 2, the plurality of photodiodes may have a plurality of photos at a predetermined interval. The diode may be disposed. Preferably it may be arranged while forming a lattice spacing of about 3-7mm or concentric circles of about 3-7mm. In addition, the measurement processor 50 may include the one photodiode 210 and the peripheral photodiode 220 surrounding the excitation light 1 (more accurately, the reflected light 2 reflected by the reflector 30). Direction measuring module 511 for determining the direction of vibration based on the information measured between any one of the) and the reflected light 2 of the one photodiode 210 and surrounding photodiodes 220 It may include an intensity measurement module 512 for determining the intensity of vibration based on the interval measured between any one.

That is, in the state where a plurality of photodiodes are arranged as shown in FIG. 2, the reflected light 2 is always irradiated toward one photodiode 210 at all times, and when vibration occurs, as shown in FIG. 3. In addition, the reflected light 2 moves between the one photodiode 210 and the peripheral photodiode 220 around the photodiode 210 in various directions. In this case, the directional measurement module 511 includes the reflected light 2 having one photodiode 210. The direction of vibration is determined based on the direction of movement between the photodiode 220 and the peripheral photodiode 220. The intensity measurement module 512 moves the reflected light 2 between the one photodiode 210 and the peripheral photodiode 220. The strength of vibration is measured based on the time of the interval. As described below, information on the direction of the vibration measured and determined by the direction measurement module 511 may be usefully determined to determine whether the vibration is a simple vibration or a vibration caused by an earthquake. The information on the intensity of vibration measured and judged through) increases the management efficiency by predicting the damage and the degree of damage to the switchboard.

In addition, the generation measurement module 510, the earthquake measurement module 513 to determine the earthquake occurrence based on the information in which the vibration in the horizontal direction is first measured through the direction measurement module 511 and then the vibration in the vertical direction is measured. And, through the direction measurement module 511 may include a vibration measurement module 514 to determine the generation of a simple vibration on the basis of the information measured only the vibration in a specific direction or mixed in the random direction.

The seismic measurement module 513 is configured to accurately measure and determine whether vibration is a vibration caused by an earthquake. When an earthquake occurs, two seismic waves (P wave and S wave) are generated and influenced. Propagated at a speed of about 7 to 8km per second and horizontally waving, S wave propagates at a speed of about 4 to 5km per second by waving the medium vertically, and the seismic measurement module 513 reflects the characteristics of the earthquake. After the vibration in the horizontal direction is first measured through the direction measuring module 511, and then the information in which the vibration in the vertical direction is measured is transmitted, it is determined that the vibration caused by the P wave and the vibration caused by the S wave afterwards are determined. Based on this, it is possible to identify the vibration caused by the earthquake and to provide relevant information so that it can accurately take into consideration the damage or maintenance of the switchgear.

The vibration measuring module 514 is configured to determine whether the vibration generated in the switchgear is a simple vibration (impact, etc.), and when the vibration is not caused by the earthquake, the vibration generated in the switchgear simply vibrates only in a specific direction. Since the vibration is mixed in a random direction without stopping or regular directionality or regularity, the vibration measuring module 514 uses the direction measuring module 511 to reflect the characteristics of the simple vibration. Based on the information measured only in the vibration of a specific direction or mixed in the random direction, it is possible to determine the occurrence of a simple vibration and to provide the corresponding information based on this, so that it can accurately take into consideration the damage or maintenance of the switchgear caused by the simple vibration. .

On the other hand, according to another embodiment of the present invention, the light receiving unit 20 includes a light guide plate 40 on the front, so that the excitation light 1 (more accurately reflected light 2) on the light guide unit 20 It can be detected by the 40 so as to be detected by a number of sensors (for example, photodiode) in the vicinity and can be confirmed by the calculation of the exact light receiving position.

That is, the light guide plate 40 is configured to diffuse when the light hits, and when the light guide plate 40 is installed on the front surface of the light receiver 20, as shown in FIG. 4, the light guide plate 40 is received by the light guide plate 40. The reflected light 2 received at 20 may be measured on a plurality of photodiodes, instead of any one of photodiodes which are diffused and arranged at a predetermined interval as described above, wherein the plurality of measured photos By calculating the center points of the diodes (which can be calculated through the measurement processing unit 50 described above), the exact center position of the actual reflected light 2 can be confirmed. In such a structure, even if the plurality of photodiodes are arranged in a relatively small density, the reflected light 2 can be measured, so that the number of sensors, that is, photodiodes, can be reduced in the absence of the light guide plate 40. You have an advantage. That is, even if the photodiodes are arranged at relatively wide intervals, the measurement can be accurately performed without missing the reflected light 2.

In the above, the Applicant has described preferred embodiments of the present invention, but these embodiments are merely one embodiment for implementing the technical idea of the present invention, and any changes or modifications may be made as long as the technical idea of the present invention is implemented. Should be interpreted as being within the scope.
