Description

Distribution board safety management system that includes the door lock control function of the distribution board that requires inspection {SAFETY MANAGEMENT SYSTEM FOR DISTRIBUTION PANEL WITH DOOR LOCK CONTROLLING FUNCTION FOR DISTRIBUTION PANEL REQUIRED TO INSPECTION}

The present invention relates to a switchboard safety management system including a door lock control function for a switchboard that requires inspection to stably manage a plurality of switchboards including a high-voltage switchboard, a low-voltage switchboard, and a motor control panel installed in a building, in more detail. is a door lock control function for switchboards requiring inspection that is connected to transmit and receive data to each switchboard through a communication network and can remotely manage the status of door locks installed in each switchboard, including the high-voltage switchboard, low-voltage switchboard, and motor control panel. It relates to a switchgear safety management system that includes.

Currently, as the number of buildings increases and the size of buildings increases, the use of power equipment for precise control is increasing due to high-tech commercialization.

In particular, in the case of a place where multiple buildings are separated by a certain distance, multiple power facilities are installed in each building, and power is supplied at the same time through a switchboard for multiple power facilities. As a result, the switchboard is used to prevent wiring from being burned out. There are a lot of fire hazards due to this.

Additionally, if a fire occurs in a distribution device such as a high-voltage switchboard, a low-voltage switchboard, or a motor control center (MCC), the distribution device and wiring work must be redone, resulting in problems such as huge expenditures on construction costs and delays in power supply. It happens. Therefore, managers need to periodically check the status of the switchboard.

Additionally, distribution devices such as high-voltage switchboards, low-voltage switchboards, and motor control boards have multiple power cables to supply power to multiple different locations. In other words, the manager manages the distribution device by checking the status of each power cable, but the reality is that maintenance is not smooth due to the difficulty in visually determining the status of the distribution device.

In addition, it can be considered an inefficient management method for managers to periodically check multiple distribution devices installed in multiple buildings one by one, considering that fires do not occur frequently in distribution devices.

As such, a switchboard is equipped with a large number of electronic devices, so in order to function normally, conditions such as temperature and humidity must be maintained at an optimal level. It is usually installed in a location where human activity is rare, or the internal condition is monitored. Since it is difficult to detect or judge from the outside, fire may occur due to external factors such as lightning, internal factors such as component failure, deterioration, insulation breakdown, or electrical leakage due to aging of lines or equipment, or failure of various components or malfunctions. There is a problem in that it is not possible to respond quickly when an issue arises.

In order to solve the above-mentioned problems, a technology for monitoring and managing the status of distribution boards or distribution boards has been developed, such as Republic of Korea Patent Publication No. 10-2010-0138248, “Electrical safety monitoring system for managing the status of distribution boards and distribution boards installed in each region.” It has been done. This technology has a local server for each region, detects data from the distribution board and distribution board, and predicts electrical fires based on this.

In addition, technology to monitor fires in distribution devices has been developed, such as Republic of Korea Patent Publication No. 10-2008-0098950, “Fire monitoring system for distribution devices.” This technology wirelessly transmits the status information detected from the sensor installed in the distribution device to the relay device, and when an abnormal condition is detected from the sensor, the abnormal status information is wirelessly transmitted in real time and the central management device displays the status information. .

In addition, an example of a technology that graphically displays the status of various modules mounted on a switchboard and provides it on a website has been developed as Republic of Korea Patent No. 10-0491528, “An integrated management system for switchgear with a touch screen function.”

However, the above-described prior art only monitors the status of distribution devices individually and displays status information, but does not systematically manage the inspection schedule of each distribution device, and requires multiple keys to unlock the door of each distribution device. There was a problem with having to go.

Republic of Korea Patent No. 10-1295779 (announced on August 16, 2013) Republic of Korea Patent No. 10-1336571 (announced on December 3, 2013) Republic of Korea Patent No. 10-0491528 (announced on May 27, 2005) Republic of Korea Open Utility Model No. 20-2008-0003282 (published on August 13, 2008)

Additionally, the switchboard 100 may be equipped with an electromagnetic field detection sensor that detects an electromagnetic field flowing in the switchboard 100. This electromagnetic field detection sensor detects the electromagnetic field flowing in the distribution board 100 under the control of the control module 160. At this time, the control module 160 checks the electromagnetic field flowing through the switchboard 100 through an electromagnetic field detection sensor, and if there is a risk of electric shock to the inspector, it provides a cutoff signal to the breaker to block the current flowing into the machine.

Additionally, the switchboard 100 may be equipped with an approach detection sensor that detects objects approaching around the switchboard 100. This approach detection sensor generates an approach detection signal when an object approaches the distribution board 100 and provides it to the control module 160. At this time, the control module 160 determines whether a door lock control signal requesting release of the door lock 130 is received, and if the door lock control signal is not received, a touch screen or operation is used to prevent the object from approaching the distribution board 100. A warning message is output through the display unit.

For example, if the electromagnetic field inside the switchboard 100 is below the standard value, “out of power” is output through the touch screen, and if the electromagnetic field is above the standard value, “energization” or “danger” is output to inform the inspector in advance of the switchboard (100). ) to notify the status of

On the other hand, since the text output through the display device such as the touch screen can only be recognized by an inspector close to the distribution board 100, the control module 160 is configured to: By controlling the warning lights, buzzers, or both installed in the case 110, people approaching the switchboard 100 can be notified of danger.
