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

FIG. 2 is a block diagram of a power distribution line live tester according to an embodiment of the present invention, FIG. 3 is a front perspective view of a distribution line live tester according to an embodiment of the present invention, FIG. 1 is a cross-sectional view showing the first embodiment.

As shown in FIGS. 2 to 4, the distribution facility live wire tester of the present invention includes a main body 100 formed of a rectangular housing having a distribution facility therein, a monitor 110 formed on a side surface of the main body, And an alarm unit 130 for notifying the user of the risk of electric shock. The detection unit 130 checks whether the user is within the risk of electric shock by using the detection sensor, And a control unit (200) for controlling the alarm unit to inform the user of the risk of electric shock when the voltage is within the danger of electric shock.

Specifically, the main body 100 is formed in a rectangular housing with a built-in distribution facility used in a real field to feel presence feeling. The main body 100 may be formed as a cubicle installed in the field. The main body 100 is formed with a partition wall portion 140 dividing the inside of the main body 100 into a front portion and a rear portion so that the front portion of the main body 100 can be equipped with a special high pressure or high pressure distribution facility, have.

The monitor 110 is formed on a side surface of the main body 100, and is configured to display a voltage applied to a power distribution facility inside the main body 100 so that the user can confirm the voltage. The monitor 110 may be provided not only on the side surface of the main body 100 but also on the front surface and the rear surface of the main body 100 so that the user can more conveniently check the voltage applied to the power distribution apparatus. In addition, the monitor 110 may display not only the voltage but also the power factor, the current, the power, and the accessible distance depending on the voltage.

The detection sensor 120 is formed in the main body 100 in a configuration for confirming whether or not the user is within the danger of electric shock from the power distribution facility. The plurality of detection sensors 120 are installed on both sides of the main body 100 at predetermined distances from the power distribution facilities and are divided into distances accessible to the power distribution facility depending on the strength of the voltage.

Generally, the range of electric shock hazard of power distribution equipment according to the voltage strength is within 20 [cm] of 22.9 [KV], 6.6 [KV] within 6 [cm] of power distribution facility, 3.3 [KV] Cm, and the low voltage should not be in direct contact with the power distribution device. Therefore, the sensing sensor 120 is connected to the first sensing sensor 121 at a position 20 [cm] away from the power distribution facility, the second sensing sensor 122 is located at a position 6 [cm] away from the power distribution facility, and a third detection sensor 123 may be installed at a point [cm] away. In this way, the detection sensor 120 is composed of the first, second and third detection sensors 121, 122 and 123, and only the detection sensor corresponding to the intensity of the voltage is operated according to the intensity of the voltage applied to the main body 100 Or all of the detection sensors 120 are activated so that the distances of the user's power distribution facilities can be detected at various distances by the first, second and third detection sensors 121, 122 and 123.

The detection sensor 120 confirms that the user is within the risk of electric shock, and notifies the user through the alarm unit 130 that the user is in the danger of electric shock when the user is within the danger of electric shock.

Also, the sensing sensor 120 may be formed as two or more than four, depending on the usage, function, and voltage of the distribution facility live-line tester, so that the access distance of the user's distribution facility can be confirmed more precisely. The degree of danger of electric shock can be expressed by the alarm unit 120 through the control unit 200 by more precisely checking the user's accessibility to the distribution facility with the plurality of detection sensors 120.

A plurality of detection sensors 120 may be formed on the side surface of the main body 100 in the height direction so as to correspond to the keys of different users and to confirm a user's access distance from the distribution facility.

The alarm unit 130 is a configuration that notifies the user of the risk of electric shock. The warning unit 130 may include at least one of a vibrating vibration unit 131, a sound emitting unit 132, a light emitting unit 133 for emitting light, and a stimulation unit (not shown) for providing an electric stimulus . The alarm unit 130 informs the user of an electric shock hazard through an alarm, thereby preventing the user from being exposed to an electric shock.

The vibration unit 131 is configured to notify a user of a risk of electric shock by vibration and may be configured as a vibration footrest protruding forward from a lower end of the main body 100. [ As shown in FIG. 5, the vibrating unit 131 is formed so as to be housed in the main body 100 so as not to occupy a space when the power distribution facility live wire tester is not used.

In addition, the vibration intensity of the vibration unit 131 may vary depending on the intensity of the voltage applied to the power distribution unit by the control unit 200 or the approach distance of the power distribution unit of the user. The vibration intensity of the vibration section 131 changes according to the intensity or the approach distance of the voltage, so that the user can recognize the degree of danger of the electric shock hazard situation according to the intensity of the vibration.

The sound unit 132 is configured to make a sound to inform the user of the risk of electric shock. The sound unit 132 may be formed in the upper portion of the main body 100 or the main body 100 so that the user can recognize the dangerous situation more quickly when repairing or replacing the power distribution equipment in the main body 100, It can be installed separately from the main body 100 so that the surrounding people such as a co-worker who is not only heard by the user alone can be brought together to recognize the dangerous situation together.

In addition, the volume or the type of the sound 132 may vary depending on the intensity of the voltage applied to the power distribution unit by the control unit 200 or the access distance of the user's power distribution facility. Thus, the user can recognize the degree of danger of the electric shock hazard situation by changing the sound size or type of the sound portion 132 according to the intensity of the voltage or the approach distance.

The light emitting unit 133 emits light to inform the user of the risk of electric shock. The light emitting unit 133 is formed in the upper end of the main body 133 or the main body 133 so that the user can recognize the dangerous situation more quickly when repairing or replacing the power distribution equipment in the main body 100, The user can be aware of the dangerous situation together with the surrounding persons such as the co-worker, not the user alone.

In addition, the color of the light emitting portion 133 may vary depending on the intensity of the voltage applied to the power distribution unit by the control unit 200 or the access distance of the power distribution unit of the user. In this way, the color of the light emitting portion 133 changes according to the intensity of the voltage or the approach distance, so that the user can recognize the degree of danger of electric shock.

The stimulating unit (not shown) may be formed of a wearable device or a shock absorber with a configuration that notifies a user of an electric shock risk situation by giving an electric stimulus to a user with a predetermined current. The current of the stimulating part is formed to be less than 1 mA so that the user is not physically or mentally shocked.

The control unit 200 determines that the user is within the risk of electric shock by using the detection sensor 120 and controls the alarm unit 130 to notify a dangerous situation when the user is within a dangerous range. It can be formed as a device capable of performing the same communication.

The controller 200 controls the main body 100 to display the voltage to be applied as desired. Even if a voltage is not applied to the main body 100, for example, a voltage of 22.9 [KV] flows virtually in the power distribution apparatus of the main body under the control of the control unit 200 and a voltage of 22.9 [KV] , So that the user can apply the distance standard of 22.9 [KV]. When the voltage is not applied to the main body 100, the control unit 200 displays the voltage on the monitor 120 so that the students are prevented from accidental electric shock when they are educated by the power distribution line testing machine of the present invention. In addition, the control unit 200 can cut off the voltage applied to the main body 100, and can minimize the damage in case of an electric shock by blocking the voltage applied to the main body 100.

The controller 200 controls the intensity of the vibration of the alarm unit 130, the size or type of sound, and the color of the light according to the intensity of the voltage applied to the power distribution unit of the main body 100.

For example, in a power distribution system in which a voltage of 6.6 [KV] flows, the control unit 200 determines whether the user is within 6 [cm] of the risk of electric shock by the detection sensor 120, 130 to inform the alarm.

In the power distribution system in which the voltage of 22.9 [KV] flows, the controller 200 determines whether the user is within 20 [cm] of the danger of electric shock by the detection sensor 120. If the user is within the danger of electric shock, 130 to inform the alarm. At this time, the vibration unit 130 can be made stronger in vibration intensity of the vibration unit 131 and sound volume of the sound unit 132 becomes larger according to the intensity of the voltage, unlike the case of the power distribution system in which the voltage of 6.6 [KV] , The sound type of the sound part 132 changes, and the color of the light of the light emitting part 133 can be changed.

In addition, when the user is within the danger of electric shock, the controller 200 may control the intensity of the vibration, the magnitude or type of the sound, and the color of the light of the alarm unit 130 to vary according to the accessing distance of the user's power distribution facility.

For example, in the power distribution system in which a voltage of 22.9 [KV] flows, the control unit 200 operates only the first detection sensor 121 to check whether the user is within 20 [cm] To be alerted. The control unit 200 also operates the second and third detection sensors 122 and 123 as well as the first sensing sensor 121 so that the intensity of the vibration of the alarm unit 130 You can control the size of the sound, the type of sound, or the color of the light.

In the power distribution system in which the voltage of 3.3 [KV] flows, the control unit 200 operates only the third detection sensor 123 to check whether the user is within the danger of electric shock 3 [cm] A plurality of detection sensors 120 installed closer to the power distribution facility than the third detection sensor 123 that is not operated only by the third detection sensor 123 are operated to control the distance to the user's power distribution facility It is possible to control the intensity of the vibration or the sound of the alarm unit 130 to be adjusted, or to change the type of sound or the color of light.

The controller 200 may be formed separately from the main body 100 as described above, but may be formed in the main body 100.

7 is a cross-sectional view showing a second embodiment of the sensing sensor which is a main part of the present invention.

7, the detection sensor 120 is formed in the partition wall portion 140 in the main body 100. [

The detection sensor 120 is formed on the partition wall 140 of the main body 100 so that the number of sensors is smaller than that of the detection sensor 120 formed on the side surface of the main body 100, And a distance detection sensor.
