It may include a control unit that detects and monitors.

However, when the size of the switchgear main body increases according to the power demand, the installation area increases indoors or outdoors, and a plan to reduce the installation area excluding the essentially increasing area is required. It is time to develop a technology that can prevent safety accidents because it is impossible to check whether current is flowing inside the enclosure body or door before entering and exiting.

In addition, in the conventional switchgear, when fine dust including iron components in the air introduced from the outside adheres to the power equipment due to the increase in parity effect due to the electric charge and the high voltage of the line, insulation breakdown occurs, causing an electric shock as well as an arc accident. There is a problem. That is, the power facility located inside the switchgear generates heat from electric energy, and when dust accumulates, a problem that causes a short circuit or malfunction due to energization has been raised.

1 to 6, the switchboard 100 capable of controlling service according to an embodiment of the present invention includes an enclosure body 110 and a door selectively shielding an opening 111 in the front of the enclosure body 110. 120 and a guide part 130 provided in the enclosure body 110 to guide opening and closing of the door 120, and a guide part 130 disposed under the enclosure body 110 to purify the air supplied from the outside. Including installation information for the air purification unit 400 supplied to the inside, and electrical equipment (for example, a transformer) attached to one surface of the enclosure body 110 and mounted inside the enclosure body 110 When the control service unit 700 consisting of a QR code and NFC card in which location data is stored and the control service unit 700 are adjacent to the enclosure body 110, the NFC card is connected to the electric facility. It includes a smart phone 800 that receives and checks the history information together with the status information from the external management server 900.

Here, the control service unit 700 including a QR code and an NFC card is attached to the door 120 without configuring a viewing window for internal confirmation, so that the internal state can be checked through the manager's smartphone 800.

That is, when the safety manager carries the smart phone 800 registered in the management server 900 in advance and reaches the place where the switchboard 100 is installed by a certain distance, the location data registered in the control service unit 700 By performing communication between the NFC card and the smartphone 800, the current state of the switchboard installed in the field can be checked through a screen displayed on the smartphone 800.

In addition, the smart phone 800 may interwork with an external management server 900 through the NFC card to read and check various information on the corresponding switchgear stored in the management server 900.

In addition, by checking the installation information of power facilities through the smart phone 800 and checking and storing a check list (transformer in FIG. 3) for power facilities displayed on the screen of the smart phone, an external management server ( 900) can be made into a database of information on power facilities.

On the other hand, if the smartphone 800 is not registered in advance, when a QR code is photographed using a smartphone, basic information on the switchboard installed on the screen of the smartphone 800 is displayed.

That is, when the QR code is scanned using the smartphone 800, the QR code is assigned a unique code number, so when the QR code is scanned, the code for the QR code scanned toward the management server 900 The number is sent automatically. Here, the unique code number is a unique serial number provided to the manufacturer, for example, a code number such as X(1)-X(2)-X(3)-X(4), and the X (1) is a number to verify the M2M QR code, X (2) is a number to determine whether the QR code is an upper, middle, or lower control QR code, and X (3) is a number to identify which facility the corresponding facility is. It is a number for, and X(4) indicates the serial number of each QR code.

In addition, the photovoltaic paint is coated along the front edge of the control service unit 700 to operate by using electric power by itself.

In addition, the smart phone 800 is interlocked with the management server 900 by the NFC card to calculate the integrated safety index for the transformer and provide various integrated functions, and representatively, the DB through the management server 900 DB analysis function, DB diagramming function, location-based service function, linking function to other institutions (information connection and reception), and user setting function that enables data editing are displayed on the screen of the smartphone 800 to proceed with the operation. Is done.

As shown in FIG. 3, a control service unit 700 attached to one surface of the switchboard 100 and a smart phone 800 connected through communication with an NFC card of the control service unit 700 are included.

Here, the control service unit 700 is attached to one surface of the door 120 of the switchboard. In the embodiment of the present invention, a transformer mounted inside the switchboard will be described as an example to manage history.

Most of the QR code of the control service unit 700 guides the URL when scanning using the smartphone 700 to induce access to the service or allows login through the authentication process. When the control service unit 700 according to the invention connects the smartphone 800 accessed within a certain distance through communication with an NFC card, and selects a daily check, a regular check, etc. displayed on the screen of the smartphone after the service is connected, These product lines are listed.

At this time, when connected to the management server 900 through the control service unit 700 attached to the switchboard 100, question items for inspection are displayed, and the safety manager selects and checks or inputs the question items.

For example, it is connected to the management server 900 through the NFC card of the control service unit 800, and the screen of the smart phone 800 displays "These are transformer daily check items" along with the title "1. Damaged. , Is there any adhesion of dust or other foreign substances? YES/NO", "2. Is there any strange sound or smell? YES/NO", "3. Is there any leakage of oil from packing or welding part? YES/NO", "4 Isn't the mechanical vibration large? Check items are listed like “YES/NO”, and the safety manager checks the items according to each item.

Subsequently, when the safety manager finishes checking and inputting and presses the save button, a signal indicating that the inspection has been completed is transmitted to the management server 900, and the management server 900 diagnoses the transformer based on the information to be a large manager (owner). , Make it possible to share with the manufacturer.

This service method builds a more reliable DB by creating item rules so that safety managers cannot answer questions arbitrarily. That is, the safety managers selectively inspect only the products they deem necessary, but must be accessed through the control service unit 700 using the smartphone 800 registered in the management server 900 in advance, but the check question Because the items are displayed, the parties can perform a more active safety management task.

The display on the smartphone 800 selects an inspection item, checks the corresponding portion, and registers the inspection item by inputting it. At this time, when the check item is registered, the created contents are transmitted to the management server 900, and it is checked with the smartphone 800 through a result reply whether the information transmitted to the management server 900 is normally transmitted.

In addition, processing details are displayed on the screen of the smartphone 800 so that the contents processed from the management server 900 can be checked, and the safety manager registers through the job when there is an additional job and ends the inspection.

At this time, the door 120 of the present invention is rotated by sliding transfer on the enclosure body 110. That is, unlike a casement door that is opened and closed only by rotation like a general door or a sliding door that is opened and closed only by sliding, the sliding operation and the rotational operation are simultaneously accompanied and open and closed.

The enclosure body 110 may be applied as any one of a high-voltage switchboard, a low-voltage switchboard, a distribution board, a junction box, a motor control panel, and an ESS according to the structure or type of facilities installed therein. For example, the enclosure main body 110 is a main body of a switchboard having power facilities such as VCB, VCS, VC, ACB, MCCB, PCB and reactor, inverter, capacitor, measurement control module, SMPS, EMI filter, and transformer. Can be applied as

The enclosure body 110 has a substantially rectangular parallelepiped shape, and has left and right sides, rear and upper and lower surfaces, and an open opening is formed on the front. Of course, the shape of the enclosure body 110 is not limited thereto, and may be formed in a polyhedral or spherical shape including a rectangular parallelepiped. In addition, a door 120 is provided at the front opening 111 of the enclosure body 110 to selectively shield the opened space. In addition, a vibration isolator (not shown) or a seismic isolator may be provided on the bottom of the enclosure body 110 so as to respond to an external force such as an earthquake between the installation surface (eg, the ground).

As an example, the doors 120 are provided as a pair facing each other so as to shield the front surface of the enclosure body 110 from both sides, respectively, and may be provided as a single door. In addition, a door lock 121 may be provided on the door 120.

The door 120 is rotated while sliding through the guide unit 130 to perform an opening and closing process. When the door 120 is opened in a closed state, a part of the door 120 is inserted into the housing body 110, and a part of the door 120 protrudes outside the enclosure body 110.

The door 120 is made to have a set thickness range, and a pad member 123 for providing a heat insulation or sound absorption function is provided therein. For example, the door 120 may have a thickness of about 100 mm, and the pad member 123 may be embedded therein. At this time, since the door 120 is made of an insulating material and requires rigidity to cover the front surface of the enclosure body 110, it is preferable to be made of engineering plastic.

These engineering plastics are excellent in strength and elasticity, as well as impact resistance, abrasion resistance, heat resistance, cold resistance, chemical resistance, and electrical insulation, and thus can be applied as a door material of a large-scale enclosure body 110. In addition, fiber reinforced plastics (FRP), a composite material that exhibits more powerful properties by mixing engineering plastics with glass fiber or carbon fiber, may be made of the door material. Of course, the door 120 may be basically made of aluminum, stainless steel, or steel made of a steel plate.

Here, if there is a configuration made of a metal material other than an insulating material among the configurations that the user can touch or grip on the door 120, a sensitization sensor (not shown) that senses current or voltage is provided, although not shown in the drawing. A visual notification means (e.g., LED, lamp, display panel, etc.) or an audible notification means (e.g., buzzer, speaker, bell, etc.) may be provided so that the user can transmit a warning message about access or contact prohibition have.

In addition, the door 120 has a curved surface 124 or an inclined surface curved from the front to the rear of the enclosure body 110. That is, when the door 120 is closed, the front of the door 120 corresponding to the front of the enclosure body 110 is concavely curved toward the inside of the enclosure body 110, so that a strong wind blows toward the door 120 Edo can be dispersed while supporting the wind pressure efficiently.

In addition, since the front of the door 120 is made of the same curved or inclined surface in the vertical direction, and has the same curvature in the left and right directions of the door 120, the effect of increasing the rigidity in the vertical direction of the door 120 can also be expected. have. In addition, since the door 120 is made of an insulating material, a potential difference does not occur with the power equipment inside the enclosure body 110, so that a safety accident occurs even if a user (for example, an operator) contacts the door 120 from the outside. Can be prevented.

In addition, although not shown in the drawings, the curved surface 124 or the inclined surface of the door 120 may be formed of a convex curved surface or an inclined surface protruding outward from the front of the enclosure body 110, and the enclosure body 110 The door 120 may have a curved or inclined structure corresponding to a curved or inclined surface of the door 120 in a lower region or an upper region of the door 120.

A pair of fixing hinges 125 and 126 are provided on the upper and lower surfaces of the door 120 to limit the transfer range through the guide unit 130. Of course, depending on the size or weight of the door, only one of the upper or lower surfaces of the door 120 may be provided with a fixing hinge.

The fixing hinges 125 and 126 include a first fixing hinge 125 disposed adjacent to an outer edge of the door 120 and a second fixing hinge 126 disposed adjacent to the center of the door 120 do. The first fixing hinge 125 and the second fixing hinge 126 may be provided with at least one or a plurality of bearings 127, and these bearings 127 provide a function of reducing friction with the guide part 130 do.

In addition, the door 120 may maintain a fixed state on the enclosure body 110 and may reduce frictional force during sliding transfer. Although not shown in the drawings, the door 120 is coupled to be capable of sliding or rotating at least around the opening 111 of the enclosure body 110. Here, the fixing hinges 125 and 126 may be made of a metal material separate from the door 120, and may be made of the same material as the door for insulation. In addition, the door lock 121 provided on the front of the door 120 may also be made of the same material as the door 120 or at least an insulating material for insulation.

And on one door 120, the distance between the first fixed hinge 125 and the second fixed hinge 126 ranges from 20 to 50% with respect to the width of the door 120 (ratio 1:2 to 1:5). ) Can be made. More preferably, the total width of the door 120 (including the distance between the fixed hinges) compared to the distance between the pair of fixed hinges 125 and 126 may be made in a ratio of 1:3. The ratio of 1:3 can effectively reduce the dead space generated inside the enclosure body 110 while enduring the wind pressure applied in front of the door 120. Here, the ratio of the width of the door 120 to the distance between the pair of fixed hinges 125 and 126 may be changed in consideration of characteristics according to an area or installation location. The door 120 using the pair of fixing hinges 125 and 126 can safely withstand wind pressure from the front, and can prevent sudden door opening and closing, thereby preventing a safety accident.

The opening and closing operation of the door 120 on the enclosure body 110 is guided by the guide unit 130.

The guide part 130 is provided on the upper portion of the edge portion adjacent to the front and side surfaces of the enclosure body 110. Of course, in a structure in which the door 120 is fixed at both the top and the bottom, another guide part may be separately disposed under the enclosure body 110.

The guide part 130 is bent in an approximately “L” shape, and a first guide member 131 adjacent to the front surface of the enclosure body 110 and a second guide member adjacent to the side surface of the enclosure body 110 It includes (132). The shape of the guide part 130 is preferably made of at least 90 ° or more angles of the first guide member 131 and the second guide member 132.

The first guide member 131 and the second guide member 132 are provided with a transfer space 133 to accommodate and transfer the fixing hinges 125 and 126 therein. At this time, the transfer space 133 inside the first guide member 131 and the second guide member 132 is formed to communicate with each other.

A swash plate 134 in contact with a fixed hinge is provided at a connection portion between the first guide member 131 and the second guide member 132. The swash plate 134 interferes so that the first fixing hinge 125 faces in the direction of the second guide member 132 in the process of opening the door 120, and the second fixing hinge ( The interference 126 is directed toward the first guide member 131. That is, the swash plate 134 comes into contact with the fixing hinges 125 and 126 so that the process of opening and closing the door 120 is smoothly performed on the guide unit 130. The swash plate 134 may be located on the transfer space 133 of the guide unit 130 or may be disposed outside the transfer space 133.

The guide unit 130 includes one or a plurality of stoppers 135 interfering with the first fixing hinge 125 or the second fixing hinge 126 in the transfer space 133. The first stopper 135a interferes in the direction in which the door 120 is closed so as to maintain the set open range (eg, about 1/3 or 2/3 open point) in the process of opening the door 120. For example, if the door 120 passes through the first stopper 135a while the user opens the door about 2/3 (when the fixing hinge passes after contacting the stopper), the door 120 is closed in the direction in which the door 120 is closed. Since it interferes with the 1 stopper 135a, about 2/3 of the open state can be maintained.

In addition, the second stopper 135b may be further provided on the guide unit 130 to keep the door 120 completely open. For example, when the door 120 is completely opened, the first fixing hinge 125 is disposed to be adjacent to the end of the second guide member 132, and the second stopper 135b is located at this position on the guide part 130. When provided, it is possible to maintain the completely open state of the door 120.

The stopper 135 takes a structure protruding into the transfer space 133 on the guide part 130, and resiliently protrudes into the transfer space 133 or contacts the fixed hinges 125 and 126 while being in contact with the transfer space. (133) It is preferable to be provided with a structure that is pushed to the outside. Further, the position of the stopper 135 may be changed according to a range in which the door 120 is mainly opened, and a greater number of stoppers may be provided according to the degree of opening of the door 120.

The door 120 may be provided with a door closer (not shown) that exerts a force in the closing direction. Then, since a constant force always acts in the closing direction of the door 120, the stopper 135 may be arranged to interfere only in the closing direction of the door 120. Although not shown in the drawings, such a door closer may be provided to press a part of the door 120 (side or edge area), or may be provided to press any one of a pair of fixing hinges 125 and 126 .

In this way, a process of opening and closing the door 120 on the guide unit 130 is as follows.

First, when the user grips the door 120 handle (not shown) or the door lock 121 and pushes the door 120 in the opening direction, the sliding transfer of the door 120 is first performed. At this time, the first fixing hinge 125 is in contact with the swash plate 134 and changes its direction from the first guide member 131 to the second guide member 132.

As the first fixing hinge 125 enters the transfer space 133 of the second guide member 132, the door 120 rotates simultaneously with the sliding transfer. At this time, a dead space 112 is generated as the door 120 slides and rotates inside the enclosure body 110, which is a negligible value compared to the total volume inside the enclosure body 110. In addition, it is possible to adjust the arrangement of power facilities inside the enclosure body 110 so as not to interfere with the dead space 112.

When the door 120 is opened and the second fixing hinge 126 passes through the first stopper 135a, the door 120 is maintained in an open state while maintaining the set open range.

Further, when the door 120 is pushed further to completely open, the first fixing hinge 125 interferes with the second stopper 135b, so that the door can be maintained in a completely open state.

When the door 120 is closed again, the transfer space 133 of the first guide member 131 from the transfer space 133 of the second guide member 132 while the second fixing hinge 126 contacts the swash plate 134 The direction is changed. After that, the process of closing the door 120 is performed in the reverse of the door opening process.

The following is an example of comparing the installation area with the case where the existing switchgear door is installed through the door of the present invention.

7 is a reference diagram showing an installation area of the enclosure body shown in FIG. 4 according to the opening and closing of the door.

Referring to FIG. 7, FIG. 7 (a) shows an enclosure body 110 in which a door 120 is installed according to an embodiment of the present invention, and FIG. 7 (b) is a conventional enclosure body in which a general door 12 is installed. It shows (11).

First, as shown in FIG. 7 (a), the structure according to the embodiment of the present invention occupies a total area of 50400 cm2 with a width of 1800 mm and a length of 2800 mm with the door 120 open on the enclosure body 110.

In addition, as shown in FIG. 7(b), the door 12 is opened in the conventional case body 11 in a state of 1800 mm in width and 3600 mm in length, and the total area occupies 64800 cm2.

Accordingly, since the installation area of the enclosure body 110 of the present invention occupies about 77.7% of the installation area of the enclosure body 11 of the prior art, a reduction in the installation area of about 23% can be expected.

Here, since the inner area (1800mm*1800mm) of the enclosure body 110 of the present invention and the enclosure body 11 of the prior art are the same, comparing the difference in the installation area according to the door opening (compare only one of the two sides), the following Same as

First, the installation area according to the opening of the door 120 of the present invention is the opening width of the door 120 is 1800 mm, the length of the open door 120 protruding outside the enclosure body 110 is 500 mm, occupying 9000 cm2 do.

In addition, the installation area according to the opening of the door 12 of the prior art is the same as the opening width of the door 12 is 1800 mm, and the length of the opened door 12 protruding outside the enclosure body 11 is 900 mm, 16200 cm2. Occupy.

Therefore, it can be seen that the installation area required for door opening and closing of the present invention is about 55.5% of the installation area required for door opening and closing of the prior art, which requires almost half the installation area. Of course, even if it is sufficiently considered that a small dead space 112 occurs inside the enclosure body 110 of the present invention, it is possible to reduce the installation area by at least 40% compared to the conventional enclosure body 11 in which the general door 12 is installed. It can be.
