Meanwhile, it is preferable that the CCTV pool or the street light 10 has a mechanical stability and a protection means for achieving electrical stability so as to prevent electrical disturbance from occurring in the installed emergency call reporting terminal 20.

 Since the CCTV pool or street lamp 10 is usually made of a metallic housing which is vulnerable to insulation, an unstable voltage or current in an electric facility such as a power supply unit may damage externally connected additional facilities.

For this reason, the CCTV pool or the streetlight 10 in which the emergency call reporting terminal 20 is installed is required to have a protection means for protecting and blocking the emergency call reporting terminal 10 from external electrical influences, It is possible to prevent the communication failure of the emergency call reporting terminal 20 or to prevent the life span from being shortened.

According to an embodiment of the present invention, when the CCTV pool or the street lamp 10 on which the emergency call reporting terminal 10 is mounted is an electric facility having a metallic housing, the CCTV pool or streetlight 10 is attached to the outer surface of each metallic housing, A voltage sensing module 60 for sensing a surface voltage according to a surface current generated in the metallic housing by a partial discharge pulse generated by an internal partial discharge and transmitting the detected surface voltage may be constructed.

Specifically, in a CCTV pool or an electric facility such as a streetlight 10, a local insulation breakdown may occur in the insulation of a device such as a switchgear or a breaker, and this local insulation breakdown causes an internal discharge phenomenon.

The internal discharge causes deterioration of the apparatus, and such deterioration can determine the durability (remaining life) of the apparatus (facility), but it is not easy to detect it. These internal discharges are mainly discharged through gaps or joints in the metallic housing. When the surface voltage across the metallic housing occurs between the grounds, the ground voltage changes instantly and temporarily. The time it takes is very instantaneous.

In this embodiment, the voltage detection module 60 detects the surface voltage applied to the metallic housing to derive the stability level of the electric facility.

The voltage detection module 60 is attached to the outer surface of the metallic housing of the CCTV pool or the street lamp 10 and is provided with an internal partial discharge generated by locally breaking the insulator provided in the metallic housing such as a transformer, Is a configuration for detecting a phenomenon.

That is, when the surface current is generated in the metallic housing by the partial discharge pulse rather than directly detecting the discharge electromagnetic wave, the surface voltage is caught by the surface current. The surface voltage is sensed to recognize the internal partial discharge.

The voltage detection module 60 includes a voltage detection sensor 61 for accumulating and sensing the surface voltage as shown in FIG. 5, and a voltage detector 62 for detecting a surface voltage sensed by the voltage detection sensor 61 50 to the mobile terminal 100. [

The voltage analyzer 50 is configured to detect an internal partial discharge pulse using the surface voltage sensed by the voltage sensing module 60. The voltage analyzer 50 determines whether the discharge is caused by the internal partial discharge pulse or the like, The degree of deterioration of the electric facility is determined according to the discharge status and the type of electric discharge, and the stability level of the electric facility can be determined. By transmitting the stability level information to the central control server 30, The control server 30 is allowed to display relevant information and to maintain the CCTV Pool or the street lamp 10 having a problem or a future problem.

The method of determining the discharge status and the discharge type in the electric facility using the surface voltage in this way can be performed by various well-known techniques, so that the description thereof is omitted.

As a result, according to the present invention, the security level of the CCTV pool or the street light 10 installed in the electric emergency facility, that is, the emergency call reporting terminal 20 is grasped, and the stability of the emergency call reporting terminal And it is possible to protect the emergency call reporting terminal 20 from the electrical influence of the electric facility.

In the present invention, an embodiment of the voltage detection sensor 61 is shown in FIGS. 6A to 6C. The voltage detecting sensor 61 of this embodiment may be configured to include the detecting electrode 611, the ground electrode 612, the dielectric 613, and the BNC connecting terminal 614. [

The detection electrode 611 may be formed of a circular copper plate, and the ground electrode 612 may be formed of a circular copper plate.

The dielectric 613 is interposed between the detecting electrode 611 and the ground electrode 612 and may be made of epoxy resin. That is, the detecting electrode 611 and the ground electrode 612 are bonded to both ends of the dielectric 613.

The BNC connection terminal 614 may be configured to be coupled to the detection electrode 611 protruding through the dielectric 613 and the ground electrode 612 from the center of the detection electrode 611. The detection signal of the voltage detection sensor 61 is detected through the BNC connection terminal 614. [

The surface voltage detected by the voltage detection sensor 61 is transmitted to the voltage analysis unit 50 by the transmission unit 62.

An electric field concentration mitigation unit 615 is disposed at the edges of the detection electrode 611 and the ground electrode 612. The electric field concentration mitigation unit 615 is provided between the detection electrode 611 and the ground electrode 612, To control the phenomenon that the electric field is concentrated on the edge and the electric field is distorted. That is, to derive an accurate surface voltage value.

Here, the electric field concentration relaxation part 615 includes 5 to 10 parts by weight of antimony oxide, 5 to 10 parts by weight of aluminum powder, 3 to 5 parts by weight of polybutadiene, and 0.5 to 2 parts by weight of palladium, based on 100 parts by weight of the epoxy resin Feature.

The antimony oxide is added to the epoxy resin as a main component so as to function as a flame retardant.

The aluminum powder may cause microcracks when the subject epoxy resin shrinks with decreasing temperature. Such microcracks can function as an electric field concentration point and function to control the temperature shrinkage of the epoxy resin, In particular, the heat dissipation function is imparted by the material of the aluminum powder.

That is, when the electric field concentration relaxation unit 615 is exposed to heat, the shape of the electric field concentration relaxation unit 615 is distorted and a point at which electric field concentration occurs may be generated. The heat accumulated in the electric field concentration relaxation unit 615, So as to prevent the distortion of the shape.

Further, polybutadiene and palladium are further added to control the surface voids that can be generated in the field concentration mitigation portion 615. [ When the electric field concentration relaxation part 615 is exposed to heat, the epoxy resin reacts with other composition or the like to generate hydrogen gas. When the hydrogen employment ability is supersaturated, hydrogen is released to the outside during the temperature lowering process, It is possible to cause fine surface voids to be generated in the fine holes 615, and such fine surface voids can act as a point of electric field concentration.

In the present invention, polybutadiene is added so that the polybutadiene has a double bond that is opened in the presence of the palladium, which facilitates the fixation of hydrogen to the open double bond. Therefore, in the present invention, polybutadiene and palladium are mixed with the composition of the electric field concentration relaxation portion 615 to absorb hydrogen generated in the paste to control the formation of the surface voids.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or scope of the invention. Therefore, the technical scope of the present invention should not be limited to the contents described in the detailed description of the specification, but should be defined by the claims.
