Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

The present invention relates to a switchboard having an IoT-based deterioration detection function capable of configuring a deterioration detection sensor formed of a mold integrated with a deterioration sensor and communicating with the deterioration detection sensor and an external mobile device.

FIG. 1 is a schematic diagram of a switchboard to which a mold-integrated composite sensor according to the present invention is applied, and FIG. 2 is a block diagram of a composite sensor in a switchboard to which the mold-integrated composite sensor according to the present invention is applied.

Referring to the accompanying drawings, a switchboard to which a mold-integrated type sensor according to the present invention is applied comprises a housing 10, a deterioration detection sensor 20, and a mobile device 30.

The enclosure 10 includes a basic frame forming a switchboard, and may be formed of a frame that is easy to connect the panel to the outer surface. Although the enclosure 10 is not shown in the drawing, it includes a horizontal frame arranged in the horizontal direction, a vertical frame arranged in the vertical direction, and a vertical frame arranged in the vertical direction, A plurality of compartment spaces are provided by the partition plate.

A door is provided at one side or both sides of the housing 10, and a plurality of spaced apart spaces are provided with an automatic breaker switch, a transformer formed in the lower space, a breaker and a wiring breaker provided in the front space, A power fuse formed at a rear upper portion, a lightning arrester, and a meter transformer formed at a lower portion thereof.

In addition, the inside of the housing 10 can be partitioned into partition walls having a predetermined thickness so as to separate the high-pressure side and the low-pressure side. The wall constituting the housing 10 is made of a high- . An input side terminal of the fault section automatic switch is connected to the housing 10 through an insulative connecting member formed on the upper portion of the housing 10 from an inlet formed in the front lower side of the housing 10. A connection cable is installed on the output side terminal of the automatic breaker of the fault section so that high voltage electricity is applied to the high voltage side of the transformer through a lightning arrester, a current-like power fuse and a transformer for a meter.

In the above-configured switchgear, the connecting portion and the supporting portion of the power equipment are covered with an insulator, which causes deterioration or mechanical damage depending on the service life, installation environment and operating conditions. As the insulator is damaged, the degree of damage is deepened due to the high voltage discharge phenomenon in a short period of time, and when it is left to stand, an arc is generated, which may lead to insulation breakdown and fire.

In addition, short-circuiting and disconnection of the connecting portion may be caused by an external force such as an external vibration, such as an earthquake.

The deterioration detection sensor detects temperature and provides detection information to the user's mobile device 30. The deterioration detection module 100 includes a deterioration detection module 100, a filter module 200, a memory 300, (400), a communication interface (500), and a breaker interface (600). At this time, the deterioration sensor may be installed in a plurality of target points.

Here, the target point for detecting the deterioration detection may be an access point such as a bus bar, a transformer, and a breaker.

The deterioration detection module 100 functions to take an infrared target point of the interior and exterior of the power plant, and may be an infrared ray camera for capturing an infrared image.

The deterioration detecting module 100 may further include an infrared ray photographing module and a vibration detecting module or an electromagnetic wave detecting module capable of detecting an electromagnetic wave due to an arc.

Vibration refers to vibration applied from the outside of the switchboard, and earthquake can be seen as a typical vibration. The vibration detection module performs a function of detecting an earthquake, and receives a vibration signal measured by the vibration sensor through a sensor input terminal, stores the pattern and intensity of the vibration signal, and outputs the pattern.

An arc occurs when electricity passes through a space, when electricity flows through a damaged insulation path using ambient dust, debris, and moisture as a conduction medium, or when electricity is leaked from a high voltage transmission line, It is generated when the signal is generated. When such an arc is generated, the fault current is induced due to the high temperature of the fault current, which causes a lot of damage to the power system. The magnitude of the arc fault current is limited by the resistance of the arc and the impedance to the grounding ears. That is, a low level of fault current is not enough to trip an overcurrent device installed near the arc fault instantaneously, resulting in amplification of the arc fault, and the amplified arc enhances the damage of the power system.

Accordingly, the generation of an arc generates an electromagnetic wave, and an arc can be detected through the electromagnetic wave detecting module which detects the electromagnetic wave generated by the arc.

The filter module 200 divides the infrared image taken by the deterioration detection module 100, and detects the temperature of each of the divided regions.

The infrared image captured by the deterioration detection module 100 also includes a surrounding area including a deterioration detection target point. That is, the range of the peripheral region including the deterioration sensing object varies in the photographed image according to the separation distance between the target point and the deterioration detection module 100. At this time, when target points for detecting deterioration are installed close to each other like the inter-phase connection points of the bus bars, there arises a problem that one of the target points can not be photographed independently and detected.

In the present invention, when a plurality of objects (connection points) are included in the infrared image captured by the deterioration detection module 100, the object is divided into a plurality of regions including the object, And the temperature is detected in the divided area.

FIG. 3 is a drawing for showing an embodiment in which an image area photographed by a deterioration detecting sensor is partitioned in a switchboard having an IoT-based deterioration detection diagnosis function according to the present invention.

Referring to FIG. 3, the photographed image area is divided into three zones based on three connection points. That is, the first region 201, the second region 202, and the third region 203 are divided into one divided region and one temperature region is detected in each of the divided regions.

The memory 300 stores and measures the measured temperature detected in each of the divided areas of the filter module 200 and the reference temperature of the steady state for each area.

For example, the reference temperature and the measurement temperature stored and managed in the first region 201 may be different from the reference temperature stored and managed in the second region 202.

At this time, the reference temperature may be a temperature detected and stored in the steady state of the switchboard, or may be a temperature detected through the filter module 200 or a temperature set by the user's input. The measured temperature is a temperature detected by the deterioration detecting module 100 and the filter module 200 according to a schedule of a certain period during the operation of the switchboard. Here, when the new measured temperature is input, the previously stored measured temperature is deleted and updated to the new measured temperature.

The control module 400 compares the reference temperature and the measured temperature stored in the memory 300 to determine whether the measured temperature falls within an error range of the reference temperature, And outputs a control signal when it exceeds the error range of the control signal.

At this time, the error range may be subdivided into a normal range, an allowable range, an alarm range, and a danger range, and the control signal is configured to output a control signal according to the subdivided error range. For example, when the error range is within the normal range and the allowable range, the control signal is not generated. In the case of the alarm range, the alarm message is outputted. In the danger range, the alarm message and the breaker trip signal are outputted .

The allowable range is the maximum allowable temperature that does not cause a failure due to deterioration depending on the ambient temperature.

According to the design conditions, when the error range between the measured temperature and the reference temperature is within the normal range, the control module 400 calculates an average temperature with respect to the measured temperature and the reference temperature, And store it in the memory 300 as the temperature.

The communication interface 500 transmits a message (an alarm message or a warning message) output from the control module 400 to a mobile device equipped with a management server application application through a communication network. The communication interface 500 is connected to a communication network, The message is transmitted to the device.

When the control signal output from the control module 400 includes a breaker trip signal, the breaker interface 600 transmits a trip signal to the breaker of the switchboard. Accordingly, when the trip signal is transmitted to the breaker, the breaker is operated by the trip signal to cut off power to be distributed.

Meanwhile, the mobile device 30 may be a mobile communication terminal of a user (administrator), and may include a smart phone, a PDA or the like capable of installing the server management application according to the installation of a server management application in the mobile device 30 .

The mobile device 30 receives and displays a message transmitted from the deterioration detection sensor 20 while being connected to a communication network.

Here, the server management application may be installed in an operating system such as an Android and an iOS, and may be manufactured as software that is operable.

The fabrication process of the deterioration sensor constructed as described above can be roughly described as follows: a pattern is processed selectively using a laser on a mold made of a thermoplastic resin, and then a chip is integrated after the plating process in a state where a plating process is performed . Thus, the mold, the circuit, and the chip are integrally formed.

The above process will be described in more detail.

The process of manufacturing the deterioration sensor includes an injection process, a laser pattern forming process, a plating process, and an SMT (Surface Mount Technology) process.

1. Injection process

The injection process is a process of injecting the mold into a shape corresponding to the space in which the deterioration detection sensor is disposed in the interior of the switchgear.

The mold, which is an injection mold, can be made of thermoplastics, and various kinds of polymers capable of plastic injection molding can be used. For example, semi-aromatic polyamide (PA6 / 6T), thermoplastic ester (PBT, PET), cross-linked polybutylene terephthalate (PBT), liquid crystal polymer, polycarbonate Can be used.

The injection product includes a laser reaction agent.

The laser reactant includes a Wheeler and a metal component. Preferably, a metalorganic or heavy metal component may be used, and the metal component may be separated from other atomic bonds through a physical-chemical reaction by a laser, and may remain in a portion where the laser passes.

A three-dimensional molding such as an injection molding is formed by injection molding, and the shape of the molding is injected corresponding to the shape of the space in which the composite sensor is disposed in the switchboard.

2. Laser pattern forming process

The laser pattern forming step is a step of forming a predetermined pattern on the surface of the mold, which is an injection molded article, by using a laser.

The laser moves along a preprogrammed pattern path and is configured to move a predetermined section repeatedly or to operate along a predetermined path according to the shape and thickness of the pattern. At this time, when the laser passes through the mold which is partially bent or protruded three-dimensionally, the jig holding the plastic injection molding is rotated or moved together with the plastic injection molding so that the laser is effectively irradiated to the three-dimensionally formed portion . And may be configured to move the laser in three dimensions according to design conditions to form a pattern.

As the laser, electromagnetic radiation from a UV laser, an excimer laser or a UV emitter may be used.

Here, at the surface through which the laser passes, the atomic bonds connected to the metal component are disassociated, and the surrounding atoms can react with other surrounding components while leaving a metal component through a physical reaction or a chemical reaction. Some may evaporate and some may combine with other atoms to form other molecules. In general, some components of the surface are removed through evaporation, and only metallic components can remain.

Through the above process, since the wheeler is not decomposed by the UV radiation applied to the mold surface, only part of the resin is removed and the wheeler is exposed. That is, the metal component of the laser-reactive agent is exposed to only a certain pattern by the laser pattern forming process.

3. Plating process

The copper plating step is a step of forming copper plating to a uniform thickness on the coating film formed in the strike step in the nickel plating step.

The plating solution used in the copper plating process was prepared by adding 55 to 65 ml / l of copper plating bath and supplement (QP-85-Cu-A) and 55 to 65 ml of alkali supplement (QP-85-Cu-B) to pure water 850 to 860 ml / (QP-85-Cu stabilizer) and formaldehyde (HcHo) in an amount of 15 to 20 ml / l, a stabilizer (QP-85-Cu stabilizer) and 8 to 10 ml / The mold is immersed in the plating liquid at a temperature of 43 to 48 DEG C at a deposition rate of 0.5 to 0.7 mu m / 10 minutes.

The nickel plating step is a step of forming a nickel metal film on the circuit pattern.

The plating solution used in this step was a mixture of 55 to 60 ml / l of a first electroless nickel plating solution (QP60 Ni-A) and a second electroless nickel plating solution And a plating solution (QP60 Ni-B) of 140 to 150 ml / l.

Further, the first and second electroless nickel plating solutions (QP60 Ni-A and QP60 Ni-B) can be used for a long time by continuous replenishment and are excellent in bath stability, .

Also, the first electroless nickel plating solution has a smoothness of 5 to 6 탆 / hr at a low temperature under a dry condition, and the phosphorus flow rate is 3 to 6 parts by weight.
