The present invention relates to a door device of a variety of enclosure-type electrical equipment, such as high-voltage integrated switchgear, motor control panel, distribution panel, and the like, in particular to apply a vertical-type slide winding door device to the door of the enclosure-type electrical equipment to minimize its installation space And it relates to a vertical door device of the switchgear to achieve a manual and automatic opening and closing operation of the sliding door smooth.

In general, door devices of various enclosure-type electrical installations, such as high-voltage integrated switchgear, motor control panel, distribution panel, etc., are installed in a door-type or double-door type hinge system having a hinge axis at the corner of the enclosure.

Accordingly, the calculation of the required area when installing the switchboard inside the building is calculated based on the maximum open state of all doors installed in the switchboard. This is because maintenance inspection for the maintenance of the facility is impossible unless sufficient space is secured in consideration of the turning radius of the door switchgear and the closing.

Therefore, when installing electrical equipment such as switchboards in a building interior, unlike in outdoor installations having a relatively high degree of freedom in terms of installation space and installation area, the door-type door provided in the electrical equipment causes an increase in the installation space of the corresponding equipment. To prevent efficient use of building space.

In particular, when a door such as a switchgear is installed in a case-opening manner, a hinge normally mounted at the corner of the enclosure performs only a function of a rotating shaft for maintaining smooth rotation of the door, where necessary to adjust the opening angle of the door. A stopper device for each opening angle can be added separately.

 This prevents the phenomenon that the door opened during maintenance inspection and maintenance of the corresponding switchgear does not maintain its own open position due to the surrounding wind, and interferes with the worker's work such as repeating the opening and closing. Additional costs are incurred, resulting in an increase in product costs such as switchboards.

The present invention is to solve the conventional problems as described above, the object of the present invention is the installation space by applying a vertical-type slide winding door device to various enclosure-type electrical equipment, such as high-voltage integrated switchgear, motor control panel, distribution panel, etc. It is to provide a vertical door device of the switchgear that can minimize the.

Another object of the present invention is to provide a vertical door device of the switchgear that can provide a stable opening and closing operation of the switchgear door by applying a restoring force of the coil spring to the vertical sliding door device.

Another object of the present invention is to quickly open the external door of the switchgear in case of an emergency such as a power failure or fire accident while improving the operability and security of the switchgear door. It is to provide a vertical door device of the switchgear to minimize the propagation of the accident by making it possible.

Vertical door device of the switchgear of the present invention for achieving the above object is a pair disposed in parallel between the upper and the under guide rail and the upper and under guide rails installed in parallel to correspond to each other in the upper end and the lower end of the front interior of the switchgear enclosure. A vertical door, a coil spring coupled to both ends of the vertical door to impart an elastic force of a spring when the vertical door is opened and closed, a vertical door and a coil spring wound by the coil spring, and the electrical switchboard electrical parts. And a winding room for isolation.

Hereinafter, the present invention will be described with reference to the accompanying drawings.

As referred to herein, the front panel of the switchgear housing 10 corresponding to the outer case of the high-low voltage integrated switchgear is mounted with a vertical door 20 of vertical slide operation type divided into left and right, and the switchgear enclosure 10 Upper guide rails 11 and the lower guide rails 12 are installed in parallel with each other at the upper front end and the lower end of the inner, respectively, so that the vertical door 20 houses the upper and under guide rails 11 and 12 together. It is shown that the refractive winding within 90 ° from the inflection point of the corner portion of.

The vertical sliding operation of the vertical door 20 is composed of a plurality of door cells, and when the transparent window cell is mounted on the door cell, the refraction type that can see the inside of the switchboard without opening the vertical door 20. Window 21 is created.

Therefore, the window 21 is also bent and mounted in the winding room 27 shown in FIG. 5 by refracting at an angle of 90 degrees or less at the corner of the switchgear enclosure when the door is opened, similar to the vertical door 20.

On the other hand, Figure 3 shows that the interior of the switchgear housing 10 is exposed by the slide winding of the vertical door 20, where the low pressure portion of the switchgear by way of example, reference numeral 28 in the drawing represents a high-low pressure barrier. Reference numeral 29 denotes a low pressure controller. On the contrary, when the vertical door is applied to the high pressure part of the switchgear, the high pressure transformer or the instrument current transformer will appear.

The coil spring 26 has an influence upon opening and closing of the vertical door to help or resist the winding and release of the vertical door 20, thereby providing a smooth vertical door opening and closing operation.

In addition, the coil spring 26 and the vertical door 20 refracted and wound thereon are configured to be located in the winding room 27 for isolation from the components of the switchboard and the switchboard.

The roller 25 located at both corners of the switchgear in the figure is installed to perform the function of the guide roller to guide the smooth winding and release of the vertical door 20, the high and low pressure partition wall 28 and the low pressure controller 29 Since it corresponds to the structure and components shown only in the low pressure portion of the switchgear seen as an exemplary condition of the present invention, when the vertical door 20 is installed on the high pressure side, the high and low pressure partition 28 and the low pressure controller ( 29) Instead, high pressure fuses, high voltage transformers, and instrument current transformers will be shown.

Figure 7 shows the configuration of the door opening and closing control circuit applicable to the vertical door automatic opening and closing device of the present invention.

As referred to herein, the controller 40 has an accident detection signal of the accident detection unit 43 including an electrostatic sensor 44, a fire sensor 45 and the like and a password for opening the door from the number keypad 46. The signal is connected to be input, and the alarm signal and the motor driving signal generated by the controller 40 are connected to control the alarm unit 56 and the motor driving unit 55, respectively.

The controller 40 includes an accident discrimination reference data memory 41 and an authentication data memory 42, and each of the information input from the accident detector 43 and the number keypad 46 is an accident discrimination reference data memory ( 41) and the data of the authentication data memory 42 are connected to each other so as to output an alarm signal for alarming an abnormal state and a drive motor control signal for opening and closing the door.

The controller 40 has a remote control IR receiver 47 and an IR remote control 51 using an infrared ray as a carrier, instead of a number keypad 46 for generating an authentication number for opening and closing of a switchboard vertical door, or a radio frequency carrier. RF receiver 48 and RF remote control 52 for remote control, or ID chip reader 49 and coin ID chip key 53 applied to a conventional door lock, or RF card having a contactless radio recognition function. By using the reader 50 and the RF card 54, an authentication number for opening / closing the vertical distribution door can be configured to be input to the controller 40 in a contact or non-contact or remote manner.

The number keypad 46 does not specify its installation position in the drawing, but may be generally installed near the handle of the vertical sliding door or near the side wall adjacent to the door, and the ID chip reader 49 or the RF card reader ( If 50) is used as an authentication key generating device for opening and closing the vertical sliding door instead of the number keypad 46, the installation position may be the same as the installation position of the number keypad 46.

On the contrary, when the IR receiver 47 or the RF receiver 48 is installed instead of the number keypad 46, the installation position of the IR receiver or the RF antenna required for these devices is not particularly limited, and is usually located at the head of the front panel of the switchboard. Expose and install.

Herein, the IR receiver 47, the RF receiver 48, the ID chip reader 49, and the RF card reader 50 of the dotted line display may be selectively installed in place of the number keypad 46.

Referring to the operation of the present invention configured as described above is as follows.

As referred to in the accompanying drawings, when the vertical door 20 is pushed outwards by using the handles provided on the vertical door 20 divided into left and right parts on the front of the switchgear housing 10, The entire vertical door 20 is formed in the coil spring 26 in the winding room 27 along the upper and under guide rails 11 and 12 installed in parallel with each other in the front upper end and the lower end of the switchboard enclosure 10. By the restoring force, the vertical door 20 is guided by the roller 25 and wound onto the coil spring 26 to open the door of the switchgear.

At this time, the restoring force of the coil spring 26 cancels the sliding movement resistance value of the vertical door 20 so that the door of the switchgear can be easily opened even without applying a large force. According to the balance between the restoring force of the spring 26 and the resistance value of the movement of the vertical door 20, the sliding vertical door maintains its door open state.

Therefore, the door open range of the switchgear can be freely determined according to the needs of the operator during the installation and maintenance of the switchgear, and thus there is no need for a separate stopper device for setting the opening angle as in the case of the conventional case-type door.

In particular, in the vertical door 20 of the present invention, when the door is opened, the door body is bent in the winding room 27 by refraction along the side wall surface inside the switchgear enclosure 10, and thus, unlike the case of the conventional casement type door opening. Since the space required for opening the door is not required, the installation space in the building such as the switchboard can be drastically reduced.

On the other hand, as shown in Fig. 4, the window cell 24 of the transparent material is inserted into and mounted in the middle part of the door cell of each of the door cells 22 constituting the vertical door 20, and these window cells 24 are mounted. The windows 21 are formed on the vertical door 20 by arranging a plurality of continuous heights and sizes, and such a window device is normally used without interrupting the slide winding operation in the switchboard of the vertical door 20. Even if the vertical door 20 of the switchboard does not open, the inside of the switchboard can be easily observed from the outside.

Figure 6 is another embodiment of the present invention, showing the structure of the forward and reverse motor block for implementing the vertical door automatic opening and closing device.

As referred to herein, the drive motor 31 is mounted on the fixed plate 30 to be fixed to one side of the switchgear housing 10, the drive motor 31 of the forward and reverse rotation control, the drive shaft of the forward and reverse motor penetrating the fixed plate 30 The forward and reverse rotational force which is fixed to the gear 32 and appears in the drive gear 32 is coupled to a winding shaft (not shown) for winding or releasing the vertical door via transmission gears 33 and 34. It is configured to be transmitted to the gear 35.

The forward and reverse drive motor 31 is configured to operate through a normal reverse control circuit in accordance with the operation of the vertical sliding door opening and closing switch (not shown) that may be provided on one side or side portion of the front door of the switchgear.

The door open / close switch may be installed as a circuit wiring for simultaneously opening and closing the left vertical sliding door and the right vertical sliding door, or may be installed as an independent circuit wiring to selectively open and close the left and right vertical sliding doors.

Referring to the operation of the vertical door automatic opening and closing device configured as described above is as follows.

First, the vertical door 20 divided into the left and right portions of the front panel switchgear housing 10 is operated by a corresponding switch when the door opening / closing switch which is provided at one side of the front panel or side surface of the switchboard cabinet is operated to the door open side. The selected left or right vertical door 20 has a switchboard enclosure 10 along an upper guide rail 11 and an under guide rail 12 installed in parallel to correspond to each other at the front upper and lower ends of the switchboard enclosure 10. The vertical sliding door opens as it is wound around a winding shaft installed near the inner edge.

That is, when the drive motor 31 of the forward / backward drive motor block rotates in the direction for opening the vertical door by the operation of the door open switch, the rotational force is driven by the drive gear 32 and the transmission gears 33 and 34. Since it is transmitted to the winding gear 35 through, the winding shaft provided in the center of the winding gear 35 is rotated, the vertical door 20 is wound by the rotation of the winding shaft is to open the door.

On the contrary, when the opening / closing switch is operated by closing the door, the driving motor rotates in the driving direction opposite to the previous driving direction, thereby releasing the vertical door 20 wound on the winding shaft of the winding gear 35 to close the door. The action will take place.

In particular, the electric opening and closing of the vertical door according to the present invention, because the switchgear check and maintenance workers can arbitrarily adjust the opening and closing amount of the vertical door through the stationary control of the drive motor, as in the case of the conventional casement type door to set the opening angle separately No stopper device is required.

On the other hand, the electric opening and closing of the switchgear vertical door can be controlled through a remote or contact or contactless or keying method.

As shown in FIG. 7, when the number keypad 46 is installed as a security means in the door apparatus of the switchgear, when the password is input to open the door to the controller 40 by operating the number keypad 46, the controller 40 ) Compares this with the password registered in the authentication data memory 42 and outputs the open control signal of the vertical door to the motor driving unit 55 to open the electric door opening operation of the switchgear according to the driving of the driving motor 31. This is done.

When the IR receiver 47 and the IR remote control 51 are applied to the switchgear door opening / closing security means instead of the number keypad 46, the switchboard manager and the operator operate the IR remote control 51 to register a password in advance. When the IR signal is input to the controller 40 through the IR receiver 47, the controller compares the information value of the input IR signal with the authentication data memory 42 value, the IR remote control of the authorized person According to the operation command to open the electric switchgear vertical door through the drive motor 31.

This operation is performed by the RF receiver 48 and the RF remote control 52, or the ID chip reader 49 and the ID chip key 53, or the RF card reader (instead of the number keypad 46 as the door opening and closing security means of the switchboard). The same also occurs when the switchgear vertical door is opened and closed by using the contact 50 or the contactless or remote method using the RF card 54).

The RF receiver 48, the RF remote control 52, the ID chip reader 49 and the ID chip key 53, the RF card reader 50 and the RF card 54 are controllers for authentication data (password) for opening and closing the door. In the carrier (RF or IR, etc.) method to be transmitted to the 40, it is slightly different from the number keypad method described above, and the controller 40 controls the password for opening and closing the vertical door using the remote control or the ID key or the RF card. The technical configuration to convey to the recognition is substantially the same.

That is, when the IR receiver 47 and the IR remote control 51 are applied as the opening / closing control means of the switchgear vertical door, the remote control signal of the IR remote control 51 passes through the IR receiver 47 using infrared rays as a carrier and the controller 40. When the remote control RF receiver 48 and the RF remote control 52 are applied as the opening / closing control means of the switchgear vertical door, the remote control signal of the RF remote control 52 is the RF receiver 48 using the radio frequency as a carrier. When the ID chip reader 49 and the coin-type ID chip key 53, which is applied to the normal door lock, are applied to the controller 40 through the switch 40, the ID chip key 53 is applied. The stored password is input to the controller 40 via the ID chip reader 49 in a contact manner, and the RF card 54 when the RF card reader 50 and the RF card 54 having a non-contact radio recognition function are applied. The data contained in the Electromagnetic Induction Method By the RF card reader 50 is input to the controller 40, it is possible to control the electric opening and closing of the switchgear vertical door according to the remote or direct operation of the manager or operator.

On the other hand, when an abnormal state occurs in the switchboard, the controller 40 outputs a control signal for automatically opening the vertical sliding door to the motor driving unit 55.

This means that in case of an emergency such as a fire or a power outage in the switchboard, this emergency takes precedence over the security of the switchboard so that the vertical door is automatically opened so that anyone can take emergency response with a fire extinguisher.

Whether the situation in the switchboard is an emergency condition is converted into a sensing signal of the electrostatic sensor 44 and the fire sensor 45 in the accident detecting unit 43 input to the controller 40, and then the reference data memory of the accident discrimination in the controller. The controller 40 outputs an alarm generation signal for emergency warning to the alarm unit 56 when the preset reference value is exceeded, that is, when a fire accident or a power failure occurs. In addition, the vertical door open control signal is output to the motor driving unit 55 at the same time as the alarm generation signal to control the electric opening and closing of the electric vertical door of the switchgear, in particular the electric opening and closing of the vertical external door of the switchgear.

This automatic switchgear door opening and closing operation in an emergency creates an environment that can quickly block other accidents from fire or power outage.

As described above, the present invention can achieve a unique effect of minimizing the installation space by applying a vertical type sliding door device to various enclosure-type electrical equipment such as a high and low voltage integrated switchgear, a motor control panel, and a distribution panel.

In addition, the present invention uses a restoring force of the coil spring can not only obtain a stable opening and closing operation of the switchgear door, but also the effect of facilitating or convenient manual opening or closing of the vertical sliding door.

In addition, the present invention not only improves the operability and security of the switchgear door, but also quickly opens an external door of the switchgear in case of an emergency such as a power failure or fire accident, so that emergency measures can be taken by a third party other than an administrator or a contractor. By using a fire extinguisher, the effect of minimizing accident propagation can be obtained.
