Embodiment Construction
[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0020] Such as figure 1 As shown, in this embodiment, the distribution line of substation A is divided into four sections L1, L2, L4, and L5, and a pole-mounted switch DL1, DL3, DL4 is respectively set at the end of each section of the line, and a pole-mounted switch at the end of L5 figure 1 omitted. The power distribution line of substation B is divided into two sections, L3 and L6. The pole-mounted switch DL2 is installed at the end of L3 section, and the pole-mounted switch DL5 is set at the end of L6 section. The distribution lines of substation B and substation A intersect to form a T-shaped structure.
[0021] When in normal operation, the switch DL5 on the pole is disconnected, and substation A supplies power to L1, L2, L4, and L5 section line loads; B substation supplies power to L6, L3 section line loads. When substation A is overhauled and...

The invention discloses an E-type pole-mounted-switch-based 10 KV distribution line and fault detection method. A distribution line output by an A transformer substation is divided into a plurality of sections of lines, wherein the tail end of each section of line is provided with a pole-mounted switch; a distribution line output by a B transformer substation is divided into a plurality of sections of lines, wherein the tail end of each section of line is provided with a pole-mounted switch; and the distributing line of the B transformer substation and the distributing line of the A transformer substation meet to form a T-shaped structure. According to protector devices with the pole-mounted switches in series connection and arranged at the tail end of each section of line, the problems of complex protection setting and poor adaptation mode capability of the pole-mounted switches in the power supply lines can be effectively solved; and the advantages of simple setting, low action setting value, fast fault removal, and no maloperation are achieved.
Description
technical field [0001] The invention relates to a 10KV power distribution line, in particular to an E-type 10KV power distribution line based on a pole-mounted switch and a fault detection method. Background technique [0002] The pole-mounted switch protection device installed in the existing 10KV distribution line, because the pole-mounted switch is installed at the front end of the distribution line, and the connection relationship of the distribution line between different substations is complicated, the setting is complicated, and it cannot adapt to the distribution The protection range and current direction change after the power supply is switched on the same section of the network lead to complex setting. A set of setting values can only be adapted to one wiring method, which is easy to refuse to operate or malfunction, because the switch of the distribution network line is on the pole of the line. , or distribution boxes in different areas in the suburbs, it is di...
