Description

Apparatus for judging earthquake-proof integrity for switch gear

The present invention relates to a seismic soundness determination device, and more particularly, in a switchboard and an internal device, warping, structural deformation, internal abnormal temperature determination, and internal arc occurrence conditions are always diagnosed, and when abnormal conditions occur, such as a smartphone, etc. Through the terminal, a warning signal is transmitted to nearby workers and the control center, and it is possible to constantly measure the temperature and check the deterioration state while removing the blind spot of the sensor due to various components of the switchboard to detect the occurrence of an abnormal condition. It relates to a seismic soundness judgment device for switchgear.

In general, large-scale buildings and industrial customers, such as customers with a large amount of power, cannot directly receive 110V or 220V of commercial power, so these customers receive a high voltage of 3,300V or 6,600V from the power system and return to the commercial voltage. It must be transformed, and especially in large-scale industrial customers, it has to receive extra-high voltage of 22.9kV and convert it back to commercial voltage for use. A switchboard is used as a facility for this. The switchboard is composed of a distribution board, a motor control center panel (MCC), a low-voltage board, a high-voltage board, a transformer board, and a special high-voltage board.

In general, such a switchgear is a device equipped with various instruments, a main circuit opening and closing device, and a protection relay, etc. necessary to supply power from the power system to the customer, and it is a device that always requires stable operation for stable power supply. In addition, due to the recent development of miniaturized and lightweight products, failure and burnout of the switchboard is highly likely to cause electrical disasters due to electric shock and fire due to the nature of the switchboard being installed inside the building, so ensuring high safety and operational reliability for the device is very important. Has become.

In order to ensure the operational safety and reliability of the switchgear, it is necessary not only to improve product reliability for the devices inside the switchboard, but also to ensure high reliability in operation even in poor use environments where external earthquakes and other shocks are applied. The management technology part of recognizing and preventing the occurrence of abnormal conditions in advance and ensuring proper maintenance and repair is also a very important part.

The enclosure of the switchgear is fixed by driving anchor bolts to the concrete floor inside or outside the building, and then the floor angle is assembled, and then the column angle is assembled to the floor angle. There is no design being done.

Therefore, in the case of conventional switchgear, the vibration situation is transmitted to the panel itself due to the vibration of the floor or the mechanical vibration caused by the electromagnetic force due to high power pressurization or the earthquake, and various devices installed therein are damaged by the earthquake, etc. The situation is occurring. That is, there is a problem in that it causes the flow of various devices due to distortion, structural deformation, and damage to the switchgear and internal devices, and damages from electric fire, electric shock, and blackout accidents due to arc generation are caused.

As the prior art disclosed to solve this problem, the "distribution board having a seismic function" of Korean Patent No. 10-0939475 and the "Urethane shock absorber and seismic spring-coupled switchgear of the Korean Patent No. 10-1625389 Device", etc., but all of them are limited technologies for buffering measures to reduce the impact of seismic resistance, and there is no active condition monitoring function according to the application of external shocks. Therefore, the current state of the switchgear according to the external impact cannot be visually confirmed, and thus rapid maintenance is not possible, so there is a problem in that the reliability of the switchgear cannot be guaranteed.

In addition, conventionally, in order to measure the temperature of the switchboard or power facility and the degree of deterioration due to aging, a separate temperature measuring device or a thermal imaging camera was used to directly project the temperature on the part to be measured to measure the temperature, and to check the deterioration state. Since most of the cases are estimated by periodically measuring and checking the condition of the exterior, there is a problem in that it is not possible to prevent accidents due to deterioration and the soundness of the facilities of the switchgear.

In order to solve the problems of the prior art as described above, the present invention determines warpage, structural deformation and internal abnormal temperature in the switchgear and internal devices, and always diagnoses the internal arc occurrence state, and when an abnormal state occurs, it is a smartphone, etc. By sending a warning signal to nearby workers and the control center through the terminal of the switchboard, it is possible to prevent failure of the switchgear and reduce maintenance through this, and further prevent electrical disasters such as power outages and electric fires caused by the switchboard failure. The purpose of this is to eliminate the blind spot of the sensor due to the various components of the switchgear to detect the occurrence of such abnormal conditions, and to enable constant temperature measurement and inspection of deterioration conditions at the same time.

The soundness determination unit,
Determining whether or not soundness is good for each section divided based on the detection unit through the detection result of the arc sensor and the temperature sensor,
The control unit,
Controls the lifting motor and the tilting motor to repeatedly perform lifting and tilting for a predetermined number of times within the section determined to be defective by the soundness determination unit, and determine the section corresponding to the defect and the defect to the terminal or the system When the temperature sensor is controlled to provide information, when the measured temperature is within the first set range, the soundness determination unit checks again, and the measured temperature is within a second set range higher than the first set range , The health determination unit shortens the inspection period to check again, and when the measured temperature exceeds the second set range, it is determined that it is defective and controls to provide defect determination information to the terminal or the system. Seismic soundness judgment device for use. The method according to claim 1,
The sensor elevator,
An elevating rail installed vertically in the enclosure;
An upper stopper and a lower stopper provided to prevent separation at the upper and lower ends of the lifting rail;
An elevating member in which the arc sensor and the temperature sensor are installed on the elevating rail; And
A tightening bolt that is screwed to the elevating member and pressurizes the elevating rail to fix the elevating member to a desired height in the elevating rail by tightening;
Containing a seismic soundness determination device for switchgear.
