By mounting the gripping mechanism 80 on the power transmission line 1, it is possible to prevent the operator from being separated from the hand when pulling the power transmission line 1, and it is necessary to bend the power transmission line 1 and pull it. Since there is no , it is possible to prevent damage to the coating of the power transmission line 1 or breakage or damage to the internal conductor. The sensing device unit (B) connected to the other end of the power transmission line (1) to warn the operator is connected to the other end of the power transmission line (1) with one end connected to the electrode (3) to supply power applied from the wire fixing mechanism (A) An alarm device 90 operated by The alarm device 80 and the other end of the power transmission line 1 are connected via a clamp c. At this time, the alarm device 90 is powered by the battery unit 70 when electricity is supplied to the power transmission line 1, It is operated with power and outputs an alarm sound.

By connecting the alarm device 90 to the transmission line 1, the operator can intuitively recognize the current state of the transmission line 1 through the alarm sound, thereby improving the convenience of work. The operational relationship of the present invention will be described as follows. First, after completing the installation of the wire fixing mechanism (A) by fixing the bracket (11) of the connecting bar (10) of the wire fixing mechanism (A) to the support (2) by the operator in order to wire the line, One end of the transmission line (1) is fixed to the fixing mechanism (3a) installed on the support (2), the middle part of the transmission line (1) is fixed to the fixing bracket (21) of the slide block (20), and the next transmission line ( 1) Pull the power transmission line (1) to the place where it is connected and take it, and a gripping mechanism (80) is installed at the other end of the power transmission line (1).

At this time, in order to prevent an electric shock accident of the operator, the power applied to the support 2 to which the transmission line 1 is connected is cut off so that electricity does not flow in the transmission line 1, and the transmission line 1 is also As shown in 2, even if the slide block 20 is advanced to the allowable limit position where the detection sensor 40 is turned on, the end of the power transmission line 1 is not straightened so that the electrode 3 in the bent state has sufficient margin. ) and the slide block 20 are preferably fixed to the fixing mechanism 3a and the fixing bracket 21, respectively. In the state connected as above, the operator attaches the outer surface of the gripping mechanism 80 installed at the other end of the power transmission line 1 to the other end of the power transmission line 1 in a state in which it is pulled taut with the electrode ( 3) or to the power transmission panel.

At this time, since one end of the power transmission line 1 is supported by the spring 30 while being fixed to the fixing bracket 21 of the slide block 20, when the operator pulls the other end of the power transmission line 1, the slide block 20 ) is advanced in a state supported by the spring 30, thereby preventing the power transmission line 1 from being excessively pulled. And, as shown in FIG. 6, when the operator pulls the power transmission line 1 excessively and the slide block 20 advances to the preset allowable limit position, the knob 41 of the detection sensor 40 detects it and A detection signal is output, and the detection signal of the detection sensor 40 is transmitted to the control unit 50, and the control unit 50 operates and controls the switch unit 60 that cut off the power connection by the received detection signal. It allows the current of the battery unit 70 to pass through.

Accordingly, the current is moved along the switch unit 60 that is energized with the battery unit 70 by the control unit 50 so that the current flows to the fixed electrode 3 through the cover c, and the electrode 3 A current flows to the power transmission line 1 connected to and the one end fixed to the fixing mechanism 3a, and a current flows to the alarm device 90 connected to the other end of the power transmission line 1 to generate a warning sound. In this way, the alarm device 90 of the detection device unit B is operated by the supplied electric power to inform the operator that the power transmission line 1 is being pulled excessively, and thus, the operator operates the detection device unit B ) by pulling the power transmission line 1 to such an extent that the alarm device 90 does not operate, the other end of the power transmission line 1 can be safely fixed to the fixing mechanism 3a of the other support 2 .

When the operation of installing the power transmission line 1 to the fixing mechanism 3a of the other support 2 is completed, the operator attaches the wire fixing mechanism A, the detecting device B, and the gripping mechanism 80 to the support ( 2) and the transmission line (1), and then connected to the next support (2) and the transmission line (1), and then the installation work of the next transmission line (1). When the installation of the transmission line 1 is completed through this method, after removing the wire fixing mechanism A, the sensing device B, and the gripping mechanism 80, power is applied to the transmission line 1, each It can supply power to a building or house. In addition, in the case of the electric leakage monitoring system of the transmission line configured as described above, the front end of the transmission line 1 is fixed to the fixing bracket 21 of the slide block 20 supported by the spring 30, so that the user Not only can (1) be excessively pulled, the connection between the electrode 3 of the support 2 and the transmission line 1 is loosened, or the transmission line 1 is fundamentally prevented from being damaged by excessive pulling, Since the slide block 20 is supported by the spring 30 and moves forward and backward, when the power transmission line 1 is pulled, the slide block 20 elastically moves forward and backward while the shock is applied to the transmission line 1 . it can be prevented

When the slide block 20 is excessively pulled in the wire fixing mechanism (A), the detection sensor 40 is turned on, and accordingly, the current of the battery unit 70 connected to the switch unit 60 is supplied to the electrode 3 By applying , the alarm device 90 of the sensing device B is operated, it is possible to prevent the operator from excessively pulling the power transmission line 1 . Since the alarm device 90 is operated by power supplied from the wire fixing mechanism A and applied to the transmission line 1 to sound an alarm, a separate power source is not required, so the structure is very simple and the transmission line ( Since the signal can always be transmitted accurately regardless of the installation location of 1) and the work position of the operator, the signal is always transmitted accurately, preventing operation errors from occurring and improving the operation reliability.

As shown in FIGS. 7 to 9, the electric leakage monitoring system of the power transmission line according to the present invention prevents the screw member 21c from loosening, thereby preventing the locking bracket 21 from sliding from the power transmission line 1 from being loosened. (100) is further included.
