摘要： PURPOSE:To achieve non-contact detection of phase at one time in a 3-phase transmission/distribution line, by arranging a photoelectric field sensor using a Pockets effect element near the 3-phase transmission/distribution line. CONSTITUTION:Capacitor parallel that a electrodes 10 and 10' of a photoelectric field sensor are arranged right below the center of 3-phase transmission/ distribution lines A-C to receive a horizontal electric field being divided. Potential generated between the electrodes 10 and 10' is introduced to a Pockets effect element 11 with a lead 12 and subjected to an optoelectric conversion with a light waveguide through an E/O transducer 13 and an O/E transducer 14 to obtain an AC sine wave voltage component. In other words, when three wires A-C are arranged and a voltage applied thereto correspond to any one of VR, VS and VT, voltage are detected in six arrays of phases depending on the combination of application of voltages VR, VS and VT. Then, voltage phases detected are obtained by determining a phase reference to clarify which of the voltages VR, VS and VT is applied to each one of A-C wires. This enables detection of phases of applied voltages of the wires by extracting voltage components with a photoelectric field sensor.

摘要： PROBLEM TO BE SOLVED: To prevent a foreign material from entering a part between the inner circumferential part of an insulator unit and the outer circumferential face of a pipe with expandable diameter, when the diameter of the insulator unit is expanded in order to form the connection part of a power cable by using the insulator unit. SOLUTION: A pipe 1 with expandable diameter which is formed in a pipe shape by winding a leaf spring and whose outside diameter is variable is used. When an insulator unit is shipped, the pipe 1 is inserted in a clean room so as to be brought into close contact with the inner circumferential face of the insulator unit. In its execution, the inside diameter of the pipe 1 is expanded together with the insulator unit. Thereby, the inner circumferential face of the insulator unit is protected by the pipe 1 with expandable diameter up to its execution from its shipment, and it is possible to prevent a foreign material from entering.

摘要： PURPOSE:To decide a faulty section by detecting a fault current of a power cable through a CT, driving a solenoid with the output therefrom to bend an optical fiber, and then detecting the optical loss thud produced through an OTDR at the end of the optical fiber. CONSTITUTION:When a CT3 disposed at a joint of a power cable A detects a fault current of the power cable A, a solenoid 5 is operated with the output therefrom. Consequently, a stopper 6 is removed from a lower member 4b which is urged upward by means of a spring 7 and engages with an upper member 4a thus bending an optical fiber 1. Consequently, optical loss is generated in the fiber 1 and the generating position is detected at the fiber end 1 by means of an OTDR 2. Such detection mechanism is installed at each joint and the length of the optical fiber up to the installing position is previously measured. The joint of the cable, through which the fault current passed, is then determined with reference to the loss generating point. The fault point is located by tracking the fault current passing points.

摘要： PURPOSE:To lead an optical cable into a small diameter pipe at a necessary time by complexing the small diameter pipe into a leading wire for electric power and a power transmission distribution cable beforehand and providing it in a duct line to lay the power transmission distribution cable. CONSTITUTION:After the suitable length of an optical cable 1 is inserted into a pipe 3 beforehand from one edge of a small diameter pipe 3, the compressed air is intermittently sent from a passage 6 into an adapter 5 for ventilation. On the other hand, by dislocating from the starting period of the sending-in of the compressed air, the optical cable 1 is intermittently supplied by a cable inserting device 4. Thus, the optical cable 1 is successively introduced into the small diameter pipe. At this time, the sending-in of the compressed air and the supply of the optical cable 1 by the cable inserting device 4 may be intermittently and alternately executed. Thus, at the necessary time, the optical cable 1 can be led into the small diameter pipe 3.
