Abstract

PURPOSE:To securely carry out supply and regeneration of power-running electric power by providing a feeder through sections between feeders which are connected to adjacent substations and further interposedly providing a third and a fourth diode to connect anode sides. CONSTITUTION:A feeder line 3' sectioned by sections 6a, 6c as well as diodes 7a, 7b and 17a, 17b are provided between feeder lines 2, 5 which are connected to a first and a second substation 1a, 1b respectively. And, a common node between the anodes of the diodes 17a, 17b is connected to the feeder line 3' through a thyristor 11 and a Zener diode 12 for a regenerating current. Accordingly, in whichever position among the feeder lines 2, 3' 5 and the sections 6a, 6b an electric car 8 may be positioned, a power-running electric power can be securely supplied while a regenerating power can be efficiently regenerated. Also, since the circuit is formed by the diodes 17a, 17b, the thyristor 11, and the Zener diode 12, reliability is improved.

For this reason, a six-ring segmentation device using diodes, as shown in FIG. 1, has conventionally been used. In FIG. 1, 1a and 1b are two DC substations adjacent to each other. The output side of the substation 1a is connected to the feeder line 2, and the output side of the substation 1h is connected to the electric line 5. A feeder wire 3 is connected in series to the feeder line 2 through a section 6a, and a section 60 is connected to the six-ring wire 5 with six-ring #i.

Indicates that it is in contact with. Next, the operation of the apparatus constructed as described above will be described. First of all, if an accident occurs in the military section A while the active air M8 is passing through the section 6, the accident circulation from the unsound section B to the accidental section AVc will be blocked by section 6b, so there will be no accident circulation. .

Next, when electricity M8 enters section middle section C, the power to the electric car in a healthy state is substation 1a-+feeder line 2→
Diode 7a → electricity! It is supplied via route E8. Next, when electric Ji8 passes section abYA, if an accident occurs in electric section A while pantograph 9a is in contact with feeder R3 and pantograph 9b is in contact with follower electric wire 4, then if an accident occurs in electric section A, the healthy six-ring section B Since the fault current that is about to flow from the power section B to the power section A is blocked by the section 6a and the diode 7a, no current can flow from the power section B to the fault point (not shown) in the power section A. As shown in [σ], the fault current to the adjacent six-ring section is always blocked by section 6a and diode 7a, or section 6b, or section 6c and diode 7b, so the fault current is prevented from flowing to the adjacent six-ring section via eight electric cars. Fault current will not flow between sections. However, if electricity exists under the feeder line 3.4 and the electric car performs regenerative operation, the regenerative current flows through the diodes 7a * 7b and sections 6a and 6c.
As a result, regenerative braking 7 becomes impossible. In order to eliminate such drawbacks, conventionally,
For example, the voltage of each general electric wire divided into sections is constantly monitored using a voltage detector, and the detection signal can be used to determine whether the electric car is in power running mode or regenerative running mode. An electric power system has been adopted that performs a selection system of 417 cycles between power operation and regenerative operation depending on the operating condition of the electric vehicle. The above-mentioned feeding system is implemented [is a pressure detection device and a discrimination device that discriminates the operating state of the electric vehicle based on its detection signal, and this discrimination device σ] selects zero regeneration based on the output signal. Since a control device and other equipment are required to carry out the control, the number of components increases and the overall configuration of the power evaluation device becomes very complicated.

As described above, according to the present invention, the first feeder line connected to the DC output side of the first substation and the DC output line 1111 of the second substation installed adjacent to the first substation a second feeder wire connected to the first feeder wire; a third feeder wire provided in sections between the first feeder wire and the second feeder wire; The first wire is connected to the cathode side and the third feeder wire is connected to the cathode side.
a second diode having an anode side connected to the second feeder line and a cathode 11% 11 connected to the third feeder line, the cathode side being connected to the third feeder line; A third diode connected to the first electric wire, a fourth diode whose cathode side is connected to the second electric wire, and the anodes of the third diode and the fourth diode are commonly connected, and ] The common connection point and the third feeder line? A valve is inserted in the connecting electric circuit, a switching control element for flowing regenerative current, and a Zener diode whose cathode side is connected to the third feeder line and whose anode side is connected to the control terminal of the switching control element. Since we prepared, the electricity ■ is the first feeder line,
Second Ki 1! line, third missing line and section σ)
Even if the current position is present, it is possible to grasp the operating status of the electricity I, and also to ensure that the power is supplied according to the operating status. The regenerated power V can be effectively regenerated. In addition, since it is constructed with simple circuits such as the third and fourth diodes, switching control elements, and zener diodes, the reliability of the device is extremely high, and the entire device can be constructed at a low cost. ] If you get the effect, try it.
