Description of the invention (1) Background of the invention: 1. Field of the invention: (Please read the notes on the back before filling out this page) The invention relates to a power receiving and distributing device, which has a high voltage Busbars transmit power to distribution substations, especially for ground fault protection in a power distribution installation circuit, and power distribution installation circuits use a loop power distribution system as the master from the high-voltage busbar to the distribution substation. Circuit power distribution method. Transmission of power from a feeder line to a distribution substation is generally used as a method for high-voltage power distribution in a power receiving and distribution device. In addition, an ungrounded system is generally used as a grounding system. In the ground-fault protection of non-grounded systems, a ground-type voltage comparator or capacitor-type ground voltage detector is provided at the high-voltage busbar, and the ground-fault voltage is detected through the high-voltage busbar, and further through Ground fault current detectors are provided at individual feed lines to detect ground fault currents, and the combination of these together with ground fault detection relays can be used to alert or remove ground fault lines. In addition, there are ground fault voltage detection relays at the tertiary winding terminals of the ground-type voltage comparator or at the secondary winding terminals of the capacitor-type ground voltage detector, as well as ground fault voltage detection relays and ground fault detection. The provision of a series combination of operation of the test relay allows the ground fault line to be removed and at the same time separated from the intact line and improves reliability. Different from the above system, when the power transmission method from the high-voltage busbar to a plurality of distribution substations is a loop system, the current converters are provided on the power transmission side and the power reception side, respectively, and combined with guidance The paper size of this paper applies the national standard (CNS) A4 specification (210 x 297 mm) -4-463 44 1 A7 ______B7 V. Description of the invention (2) Electrical equipment, a section of ground fault point is determined and the ground fault point Detection and removal were implemented. (Please read the precautions on the back before filling this page.) In addition, as described above, when the power transmission method from a high-voltage busbar to multiple distribution substations is a loop system, ground fault current detection The relays are provided on the receiving and transmitting sides of individual distribution substations, and through their combination with the ground fault detection relay, the operating status of the individual relays is transmitted to devices such as a central monitoring device, which can include ground monitoring and control The power receiving and distributing device, according to the relationship of the position and the relay operated, determine the fault point and send an open signal to the relevant disconnection unit in order to protect the circuit. When a ground fault occurs in any distribution substation or at the cables in the power receiving and distributing device, and the power receiving and distributing device implements from the feeder line connected to the high voltage busbar to a plurality of power distribution substations When the power circuit is in power distribution, the combination of the ground fault current detector and the ground fault detection relay generates such a problem, which is that the ground fault detection relay where the power distribution substation where the ground fault occurs unexpectedly will generate an accident. The ground fault is unexpected, but at the same time, the ground fault detection relay in the intact distribution substation can be operated according to the fault point, and the relevant circuit breaker unit is turned on and the intact distribution substation can interrupt the power supply service. 0 In addition When the failure point is determined by sending out the operating status of the relay to a device such as a central monitoring device, the device can comprehensively monitor and control the power receiving and power distribution device including the power distribution substation.

Now, for example, when it is assumed that all circuit breakers 12, 13, and 30 to 35 connected in series along the loop power distribution circuit are closed to form a power distribution loop circuit, and power is transmitted from feeders 10 and 11 to In individual distribution substations 20, 21, and 22, a ground-type voltage comparator or capacitor-type ground voltage detector 8, a ground fault current detector 14, 1 5 and 4 0 to 4 5 and Directional ground fault detection relays 16, 17 and 50 to 55 connected to the secondary or tertiary terminals above to detect ground faults in the case of open-circuit power transmission from feeders 10 and 11 . When the directional ground fault detection relays 16, 17, and 50 to 55 are operated at the same time, the A contact 16A, 17A, and 50A to 55A are closed and are in the control unit; LOA, 11A, 20A, 20B The timers set in 22A and 22B are activated. Therefore, the operation time of the timer is determined by such a relationship that the timer T 1 operates at a later time sequence than the timer T 4, and the timer T 4 operates later than the timer T 6 In the timing, the timer T 6 operates in a timing later than the timer T 8, the timer T 2 operates in a timing later than the timer T 7, and the timer T 7 operates in a timing later than the timer T 5 In the late time sequence, and the timer T 5 operates on this paper size, it applies the Chinese National Standard (CNS) A4 specification (210 x 297 mm) -19- ----- I --- ^ -----. ..Install --- (please read the precautions on the back before filling this page) -6J. --- line · 4 6 344 1 A7 B7 V.

As already explained above, the operation timing of the individual timers from the timer T 1 on one side toward the timer T 2 on the other side is continuously compared in the following order T1 > T4 > T6 > T8 Quickly decide. In addition, the operation timings of the individual timers from the timer T 2 on one side to the timer τ 1 on the other side are continuously continued in the following order T 2 > T 7 > T 5 > T 3 Decide faster. When it is assumed that the power distribution substation 22 in the power distribution loop circuit 7 induces a ground fault accident 60, the ground fault current i and the ground fault current i flow from the ground fault accident 60 to the feed use on one side Circuit breaker 12 and the feed to the other side use circuit breaker 1 3. All ground-type voltage comparators or capacitor-type ground voltage detectors 8 detect a ground-fault voltage, and the ground-fault current i is detected by the ground-fault current detectors 1, 4, 5, 4, 1 and 4 3 . When the directional ground fault detection relays 16, 6, 1 and 53 are operated in the same direction as the ground fault current i, the A contacts 16A, 51A and 53A are closed.

On the other hand, since the directional ground fault detection relay showing the same direction as the ground fault current i is only the directional ground fault detection relay 17, When the ground fault detection relay 17 is in operation, the A contact 17A is closed and the timer T2 is activated to close the A contact T2A. As a result, the interrupt command 1 3 A is output to the circuit breaker 1 3 and the circuit breaker 1 3 is tripped. . As a result, the power supply can continue to the loads L 1 and L 2 without interrupting the power supply service to all LI, L2, and L3. That is, because the ground fault accident point 60 can be removed by this, no other interruption commands 3 1 A and 1 2 A are output, and the power transmission from the feeder 1 0 continues, and it can prevent the distribution substation 2 0 and 21 1 Unnecessary power supply service interruption. Next, it is now assumed that in the power distribution circuit 7 a ground fault accident 6 1 is induced at the main circuit cable connected between the distribution substations 2 1 and 22. When the ground fault accident 61 is induced, the ground fault current i and the ground fault current i flow from the ground fault accident 61 to the feeder-use breakers 1 2 and 1 3.
