Description

Technology Field

[0001] The present invention relates to a molded transformer, and more specifically, to a molded transformer equipped with an automatic fire extinguisher that enables immediate fire suppression in the event of a fire in the molded transformer. Background Technology

[0002] Generally, a transformer is a device that changes the value of alternating current or voltage using the phenomenon of electromagnetic induction; it is also called a trans and is typically used to convert voltage to a required value.

[0003] The basic structure consists of coils wound on both sides of an iron core to form a primary winding and a secondary winding. The iron core serves as a path for magnetic flux, and when an AC power source is connected to the primary winding, current flows and alternating magnetic flux is generated in the iron core. This magnetic flux links with the secondary winding and changes alternately according to the frequency of the AC current, thereby generating voltage in the secondary winding. Consequently, the voltage can be controlled according to the coils wound in the primary and secondary windings.

[0004] Here, a transformer in which the winding portion of a coil wound around an iron core is insulated by molding it with epoxy resin is called a dry-molded transformer. Since dry-molded transformers use flame-retardant epoxy instead of insulating oil, they have a simple structure and are lightweight, so they are installed in various fields such as buildings, apartments, subways, and ships. Additionally, because they are coated with epoxy resin, they can prevent corrosion from moisture and dust, allowing them to be installed in water treatment facilities.

[0005] The molded transformer is composed of a coil assembly molded by epoxy resin with a high-voltage coil and a low-voltage coil separated and having a certain space inside, a plurality of stacked silicon steel plates installed to be exposed upward and downward through each coil assembly, and an upper frame and a lower frame that press down on the silicon steel plates exposed upward and downward, respectively.

[0006] In addition, the molded transformer is provided with a primary terminal to which a primary voltage is applied and a secondary terminal to which a secondary voltage is applied, and the primary terminals are connected by inter-phase leads for wiring, and a tap switching terminal is provided at a suitable location on the outer surface of the coil assembly to allow for a change in the tap voltage.

[0007] However, such molded transformers can cause fires due to internal winding failures, heat accumulation, or insulation softening; in such cases, fire suppression is carried out through external sprinkler systems, separate fire extinguishing systems, or the spraying of fire extinguishers by nearby workers, resulting in extinguishment occurring after a delay compared to the time of initial ignition.

[0008] This leads to a fatal problem where the delay in initial fire response time allows the fire to spread to surrounding structures, potentially causing a major fire. Prior art literature

[0009] Korean Registered Patent No. 10-2259422 The problem to be solved

[0010] The present invention was devised to resolve the aforementioned problems and technical biases, and aims to provide a molded transformer equipped with an automatic fire extinguisher that can suppress a fire in its early stages by immediately detecting the temperature at a nearby location and spraying a fire extinguishing agent when a fire occurs in the molded transformer. means of solving the problem

[0011] A molded transformer equipped with an automatic fire extinguisher according to the present invention for achieving the above objective comprises: a molded transformer; and a plurality of fire suppression units positioned in close proximity to the molded transformer such that the automatic fire extinguisher can rotate up, down, left, and right and move up, down, left, and right, and the spray direction of the automatic fire extinguisher is always aimed at the predicted fire area so that the automatic fire extinguisher can immediately spray a fire extinguishing agent to the predicted fire area of ​​the molded transformer.

[0012] Here, the fire suppression unit preferably comprises: a horizontal base having a predetermined length; at least one vertical base having a predetermined length that is fixed so as to be movable along the longitudinal direction of the horizontal base and arranged in a direction orthogonal to the horizontal base; and at least one fire extinguisher aiming unit that is optionally fixed along the longitudinal direction of the vertical base and sets the direction of the automatic fire extinguisher toward the fire prediction unit of the mold transformer.

[0013] In addition, a horizontal slot is formed along the longitudinal direction in the horizontal base, and it is preferable that the vertical base is fixed to the horizontal base through a fastener that penetrates the horizontal slot.

[0014] Meanwhile, it is preferable that the vertical base has a plurality of fastening holes formed along its length through which fasteners pass so that the selected height of the fire extinguisher aiming unit can be fixed, and a vertical slot formed in the center of its length through which a signal cable connected to the fire extinguisher aiming unit passes.

[0015] In addition, the fire extinguisher aiming unit preferably comprises: a fixing member having a predetermined area and having a fixing piece formed on one side that is selectively fixed along the longitudinal direction of the vertical base; a horizontal rotating member that is selectively fixed to the plate surface of the fixing member so as to be rotatable left and right, and has a pair of support panels formed spaced apart having a predetermined length; and a vertical rotating holder that is rotatably coupled to the support panel of the horizontal rotating member so as to be rotatable up and down and is equipped with an automatic fire extinguisher.

[0016] Additionally, at least one pair of spaced-apart curved slots are formed on the plate surface of the fixed member so that the horizontal rotating member can be positioned in a selected rotational direction, and it is preferable that the horizontal rotating member is fixed in the selected rotational direction by a fastener penetrating the curved slot and the horizontal rotating member.

[0017] In addition, it is preferable to form protruding rotation shafts on each side of the vertical rotation holder, and to fix the rotation position of the vertical rotation holder by connecting a fixing knob to the rotation shaft through the support panel.

[0018] Finally, it is preferable that the above automatic fire extinguisher is a heat-sensitive fire extinguisher that sprays a fire extinguishing agent in response to a set temperature. Effects of the invention

[0019] According to the mold transformer equipped with the automatic fire extinguisher of the present invention having the above configuration, a plurality of fire suppression units are installed in close proximity to the mold transformer, and the spraying direction of the automatic fire extinguisher of each fire suppression unit is set to be aimed at the direction in which a fire is predicted at any time, thereby providing an excellent effect of enabling the automatic fire extinguisher to quickly detect the temperature and spray a fire extinguishing agent to achieve immediate initial suppression when a fire occurs.

[0020] In addition, since the automatic fire extinguisher has a structure capable of rotating and moving up, down, left, and right, it offers excellent structural effectiveness by enabling targeting to specific locations in response to changes in the fire extinguishing area caused by the size and structure of the mold transformer.

[0021] In addition, since the automatic fire extinguisher is detachable, it offers the advantage of easy replacement and maintenance. Brief explanation of the drawing

Specific details for implementing the invention

[0027] As shown in FIGS. 1 to 6, the mold transformer (100) equipped with the automatic fire extinguisher (270) of the present invention comprises: a mold transformer (100); and a plurality of fire suppression units (200) that position the automatic fire extinguisher (270) in close proximity to the mold transformer (100) so as to be rotatable up and down and move up and down and left and right, and aim the spray direction of the automatic fire extinguisher (270) at the predicted fire area so that the automatic fire extinguisher (270) can immediately spray a fire extinguishing agent to the predicted fire area of ​​the mold transformer (100).

[0028] Before explaining, the feature of the mold transformer (100) equipped with the automatic fire extinguisher (270) of the present invention is that the automatic fire extinguisher (270) maintains a constantly aimed state toward the area where a fire is predicted by rotating up, down, left, and right and moving up, down, left, and right while in close proximity to the mold transformer (100), thereby enabling immediate response in the event of a fire.

[0029] In addition, the fastener (F) described below is typically capable of mechanically joining or separating two or more objects. In this embodiment, it may be a bolt and nut for joining and separating structures described below, and various types of fasteners (F) may be applied.

[0030] In addition, the binding hole (C) through which the fastener (F) passes is to be assigned the same symbol.

[0031] A molded transformer (100) comprises a coil assembly (110) molded with epoxy resin to form a certain space (a space through which silicon steel plates pass) inside, with a high-voltage coil and a low-voltage coil separated therefrom, a plurality of silicon steel plates (120) installed to penetrate the space of the coil assembly (110) and be exposed to the upper and lower ends of the coil assembly (110), a pair of upper frames (130) and lower frames (140) each coupled to the silicon steel plates (120) exposed to the upper and lower ends of the coil assembly (110) and pressing the plurality of silicon steel plates (120) with pressure, and a plurality of upper and lower frames (130, 140) arranged between the coil assembly (110) and the upper and lower frames (130, 140) to maintain an insulation distance, block noise and vibration of the structure, and fix the position of the upper and lower frames (130, 140). It consists of upper and lower spacers (150, 160).

[0032] In addition, the coil assembly (110) is provided with a primary terminal (111) to which a primary voltage is applied and a secondary terminal (112) to which a secondary voltage is applied, and the primary terminals (111) are connected to each other by inter-phase leads (113) for connection, and a tap switching terminal (114) is provided at a midpoint in the longitudinal direction of the coil assembly (110) to allow for a change in the tap voltage.

[0033] As the structures described above are the conventional structures of a mold transformer (100), further detailed descriptions below will be omitted.

[0034] The above mold transformer (100) can be fixedly installed by being placed on the upper part of a connecting base (P) of a metal structure having a predetermined area placed on the ground as shown in FIG. 1.

[0035] At this time, it is preferable that the mold transformer (100) be installed at the longitudinal center of the connection base (P), so that the fire suppression unit (200), which will be described later as in FIGS. 1 and 2, can be positioned on both sides centered on the mold transformer (100).

[0036] Here, the connection base (P) allows the molded transformer (100) and the fire suppression unit (200) to be included as a single object, and it is obvious that it can be connected to a conventional transformer enclosure.

[0037] Meanwhile, in the present invention, since there is always a possibility of ignition when the winding and iron core parts of the mold transformer (100) are heated to a high temperature or when insulation breakdown or overload occurs, a fire suppression unit (200) that responds immediately when a fire occurs may be installed.

[0038] The fire suppression unit (200) is designed so that the spray direction of the automatic fire extinguisher (270) is always directed toward the predicted fire area, so that immediate initial suppression can be carried out when a fire occurs in a specific area of ​​the mold transformer (100) where a fire is predicted, and the extinguishing agent can be sprayed immediately when a fire occurs.

[0039] The fire suppression unit (200) is positioned on the left and right sides of the connection base (P) as shown in FIG. 1 so as to be positioned close to the periphery of the mold transformer (100), and can be detachably fixed through fasteners (F).

[0040] At this time, the fire suppression unit (200) can be positioned so that the automatic fire extinguisher (270) can be rotated up, down, left, and right and moved up, down, left, and right in the drawing while fixed to the connecting base (P).

[0041] Meanwhile, bringing the fire suppression unit (200) close to the mold transformer (100) is intended to concentrate the spray of the fire extinguishing agent sprayed from the automatic fire extinguisher (270), and it is desirable to maintain a distance of 300mm to 500mm from the mold transformer (100) so that the tip of the automatic fire extinguisher (270) does not interfere with the mold transformer (100) when rotating and moving. If the distance is 300mm or less, it is difficult to secure the spraying distance of the automatic fire extinguisher (270), so fire suppression cannot be properly carried out, and if it is 500mm or more, although the spraying distance is secured, the spraying range widens as the distance increases, which causes a problem of reduced fire suppression effect.

[0042] Additionally, the automatic fire extinguisher (270) is preferably a heat-sensitive fire extinguisher, and a signal cable (271) can be connected to the rear of the automatic fire extinguisher (270) to transmit a signal detected by a temperature sensor (not shown) installed at the fire prediction area.

[0043] In other words, a heat-sensitive fire extinguisher automatically releases a extinguishing agent when a signal indicating that a set temperature has been reached is received, allowing for initial fire suppression before the fire spreads by spraying the agent without requiring direct human operation.

[0044] For example, when the set temperature of a heat-sensitive fire extinguisher is 70 to 90 degrees, if a signal indicating a temperature of 70 degrees is received, the extinguishing agent is sprayed.

[0045] As the structure of a heat-sensitive fire extinguisher is a standard feature, a detailed explanation will be omitted.

[0046] Accordingly, the fire suppression unit (200) ensures that the spray direction of the automatic fire extinguisher (270) is always aimed toward the area of ​​the mold transformer (100) where a fire is predicted, so that when the temperature of the area where a fire is predicted reaches a set temperature, the fire extinguishing agent can be sprayed immediately.

[0047] A fire suppression unit (200) having the above functions may include a horizontal base (210), a vertical base (220), and a fire extinguisher aiming unit (230) as shown in FIGS. 2 to 6.

[0048] The horizontal base (210) can be fixed or detachably positioned at the end of the connecting base (P) through a fastener (F) while maintaining a predetermined length.

[0049] The horizontal base (210) has a cross-section having a "U" shape and is preferably made of a metal material having rigidity capable of supporting the structures of the fire suppression unit (200) described later.

[0050] The vertical base (220) has a cross-section having a "U" shape and maintains a predetermined length, and the fire extinguisher aiming unit (230), which will be described later, can be installed so as to be movable along the length direction of the horizontal base (210), and two units can be spaced apart on the horizontal base (210) in a direction perpendicular to the horizontal base (210).

[0051] That is, by allowing a fire extinguisher aiming unit (230) to be installed on each vertical base (220), a total of four fire extinguisher aiming units (230) can be installed on each of the four vertical bases (220) as shown in FIG. 2, and at least one fire extinguisher aiming unit (230) can be installed on each vertical base (220).

[0052] Meanwhile, as shown in FIGS. 2 and 3, a horizontal slot (211) penetrating the horizontal base (210) may be formed so that two vertical bases (220) can be selectively movably arranged along the longitudinal direction on the horizontal base (210), and the horizontal slot (211) may be formed as one long slot or as two spaced-apart slots.

[0053] And, each vertical base (220) can be fixed upright from the horizontal base (210) by being fixed through a fastener (F) that passes through each horizontal slot (211) so that it can be fixed at a selected position on the horizontal base (210).

[0054] Additionally, a plurality of fastening holes (C) having a circular or slot shape that penetrate the vertical base (220) may be formed along the longitudinal direction of the vertical base (220), and the fire extinguisher aiming unit (230) is fixed on the vertical base (220) by passing a fastener (F) through the fastening holes (C) so that the fire extinguisher aiming unit (230) can be fixed at an optimal height selected according to the size of the mold transformer (100) or the location of the fire prediction area as shown in FIGS. 1, 2 and 5.

[0055] That is, the fastener (F) is connected by penetrating the fastening hole (C) formed in the fixing piece (241) of the fixing member (240) of the fire extinguisher aiming unit (230) described later as in FIG. 3 and the fastening hole (C) of the vertical base (220), thereby fixing the fire extinguisher aiming unit (230) on the vertical base (220).

[0056] Additionally, a vertical slot (221) having a predetermined length formed to penetrate along the longitudinal direction may be formed in the longitudinal center of the vertical base (220), and this vertical slot (221) allows a signal cable (271) connected to an automatic fire extinguisher (270) to pass through when the fire extinguisher aiming unit (230) is fixed at a selected height as in FIG. 5, thereby preventing the signal cable (271) moving according to the height of the fire extinguisher aiming unit (230) from interfering with the vertical base (220).

[0057] Accordingly, the vertical base (220) is fixed at a selected position on the horizontal base (210) by the horizontal slot (211) of the horizontal base (210), so that the position of the fire extinguisher aiming unit (230) fixed to the vertical base (220) is selectively varied along the longitudinal direction of the horizontal support piece, thereby allowing the two fire extinguisher aiming units (230) to simultaneously face a specific direction or each face a selective direction by moving the position of the vertical base (220).

[0058] In this embodiment, two vertical bases (220) are shown fixed to the horizontal base (210), but the number is not limited as they can be installed in greater or lesser quantities depending on the capacity or size of the mold transformer (100).

[0059] The fire extinguisher aiming unit (230) is set so that the direction of the automatic fire extinguisher (270) is always aimed toward the prediction section where a fire is expected to occur in the mold transformer (100), and can be fixed at a selected position on the vertical base (220) through a fastener (F) that passes through the through hole of the vertical base (220) as shown in FIG. 3 along the longitudinal direction of the vertical base (220).

[0060] The fire extinguisher aiming unit (230) may include a fixed member (240), a horizontal rotating member (250), and a vertical rotating holder (260) as shown in FIGS. 3 to 6.

[0061] The fixing member (240) maintains the shape of a flat plate with an upper surface having a predetermined area, and on one side (left side in the drawing), a bent fixing piece (241) may be formed that is selectively connected to the vertical base (220) through a fastener (F) and a binding hole (C) formed along the longitudinal direction of the vertical base (220) and fixed to the vertical base (220). Additionally, two binding holes (C) through which the fastener (F) passes may be formed in the bent piece.

[0062] A horizontal rotating member (250), which will be described later, is seated on the plate surface of the fixed member (240), and a pair of curved slots (243), each consisting of two parts of the same virtual diameter, may be formed to pass through so that the seated horizontal rotating member (250) can be positioned in a fixed state while rotating in a selected horizontal direction.

[0063] A pair of curved slots (243) can be spaced apart and facing each other as shown in FIG. 4, and forming two curved slots (243) as a set is intended to maximize the fixation of the selected rotational direction of the horizontal rotational member (250) by enabling fastening through a fastener (F) at each curved slot (243) when the horizontal rotational member (250) described later is combined.

[0064] Additionally, the center of rotation of a pair of curved slots (243) may be the longitudinal center of the horizontal rotation member (250) described later.

[0065] In this embodiment, two curve slots (243) are shown as a set, but the number is not limited as they can be formed as a single unit.

[0066] The horizontal rotation member (250) is set to rotate horizontally so that the vertical rotation holder (260), described later, faces the fire prediction area of ​​the mold transformer (100), and can be fixed by being seated on the plate surface of the fixed member (240) so as to be rotatable left and right in the horizontal direction.

[0067] The horizontal rotating member (250) maintains a plate-like shape with a flat bottom surface, and a pair of support panels (251) extending to a predetermined length are extended vertically in a spaced-apart state.

[0068] The lower side of a pair of support panels (251) may have a structure in which a horizontal rotating member (250) is interconnected to form a single unit.

[0069] Additionally, on both lower sides of the horizontal rotating member (250), a plurality of connecting holes (C) may be formed, in which the horizontal rotating member (250) is seated on the fixed member (240) and connected to a pair of curved slots (243) through fasteners (F).

[0070] Accordingly, the horizontal rotation member (250) sets the rotation direction by rotating left and right along the curved slot (243) as shown in FIG. 6 and fixing it to the fixed member (240) through a fastener (F) that penetrates the curved slot (243) at a selected position.

[0071] The vertical rotation holder (260) enables vertical rotation of the automatic fire extinguisher (270) and can be rotatably coupled between a pair of support panels (251) of the horizontal rotation member (250).

[0072] The vertical rotating holder (260) can maintain the shape of a cylinder having a predetermined width, and can accommodate an automatic fire extinguisher (270) detachably inside.

[0073] And, the automatic fire extinguisher (270) housed in the vertical rotating holder (260) can be fixed and released through a separate tightening device, etc., not shown.

[0074] Additionally, as shown in FIG. 4, a protruding rotation axis (261) may be formed on each side of the vertical rotation holder (260) so that the vertical rotation holder (260) can rotate up and down between a pair of support panels (251), and a fixing knob (263) that forms a spiral connection may be coupled to the rotation axis (261).

[0075] That is, the fixed knob (263) is connected to the rotation axis (261) by passing through the connection hole (C) formed to penetrate the support panel (251), thereby allowing the rotational position of the vertical rotation holder (260) in the up and down direction to be fixed as shown by the arrow in FIG. 5.

[0076] A fire suppression unit (200) having the above structure is not merely a fire extinguisher placed on one side of the mold transformer (100), but allows the spray direction of the automatic fire extinguisher (270) to be freely adjusted through positional movement and rotation angle toward the fire prediction part of the mold transformer (100).

[0077] The fire suppression unit (200) can be installed on the left and right sides of the mold transformer (100) as shown in FIG. 1, and can be aimed at the main fire prediction part of the mold transformer (100) by rotating and moving.

[0078] For example, when aiming toward the tap switching device (114) on the lower side of the mold transformer (100) and the secondary terminal (112) on the upper side is required, the fire extinguisher aiming unit (230) on the left side of the drawing can aim toward the tap switching device (114) without separate vertical movement, and the fire extinguisher aiming unit (230) on the right side of the drawing can aim toward the secondary terminal (112) by moving and fixing it in the upward direction through the binding hole (C) of the vertical base (220) so that a spray range toward the secondary terminal (112) can be secured as the secondary terminal (112) is located on the upper side.

[0079] As described above, the molded transformer equipped with the automatic fire extinguisher of the present invention has an excellent effect of enabling immediate initial suppression by installing a plurality of fire suppression units in close proximity to the molded transformer and setting the spray direction of the automatic fire extinguisher of each fire suppression unit to be aimed at the direction in which a fire is predicted at any time, so that when a fire occurs, the automatic fire extinguisher quickly detects the temperature and sprays the extinguishing agent.

[0080] In addition, since the automatic fire extinguisher has a structure capable of rotating and moving up, down, left, and right, it offers excellent structural effectiveness by enabling targeting to specific locations in response to changes in the fire extinguishing area caused by the size and structure of the mold transformer.

[0081] In addition, since the automatic fire extinguisher is detachable, it offers the advantage of easy replacement and maintenance.

[0082] For the above, a molded transformer equipped with an automatic fire extinguisher according to the present invention has been described with reference to preferred embodiments and the attached drawings, but this is intended only to aid in understanding the invention and is not intended to limit the technical scope of the invention.

[0083] In other words, it goes without saying that various modifications or alterations are possible for a person of ordinary knowledge in the technical field to which the invention belongs without departing from the technical essence of the invention, and that such changes or alterations fall within the technical scope of the invention in terms of the interpretation of the claims.
