Description

Novel high-low voltage switch cabinet secondary zero line ground wire wiring circuit

Technical Field

The utility model relates to a low-voltage switchgear wiring field, in particular to novel high-low voltage switchgear secondary zero line ground wire wiring circuit.

Background

Along with the rapid development of the power grid market, the market demand of the low-voltage switch cabinet increases year by year, the end user not only requires the quality and quantity guarantee, but also requires the short supply period, and particularly as the low-voltage switch cabinet, the secondary wiring is complex, the process requirement is high, the number of cables is large, the construction difficulty is high, and the later maintenance and the overhaul convenience are required to be ensured. As a manufacturer, how to adopt a simple and rapid wiring mode is very important. In order to reduce the workload, facilitate the construction and the maintenance and improve the working efficiency, a novel zero line and ground wire wiring mode is designed.

The conventional low-voltage cabinet has the defects that the primary N line (zero line), the PE line (ground line), the secondary N line and the PE line are all in pressure connection with the corresponding N row and the corresponding PE row, and the conventional low-voltage cabinet is cross-used, so that the conventional switch cabinet has low wiring mode safety, is not attractive, and has large workload and large virtual connection rate.

The low-voltage cabinet type is many, and the secondary wiring is complicated, and especially secondary N line, PE line frequency of use are quite high, and the lead wire is more, cause very big work load, and the accessible reduces the lead wire quantity by a new mode of connection.

For example: as shown in FIG. 1, each loop leads N wires independently, the wire consumption is large, the wiring is complicated, and time and labor are wasted.

As shown in fig. 2, after each loop is short-circuited in sequence, one N line is led out, and when one N line on the right side of the graph is broken, all other loops on the left side are broken, so that the fault is spread.

Disclosure of Invention

In order to solve the technical problem, the utility model relates to a novel low-voltage switchgear secondary zero line ground wire wiring circuit, its technical scheme is:

including power, wire, fuse, pilot lamp and N line, the number of power, fuse and pilot lamp is the same, is a plurality of, and every power links to each other rather than the fuse that corresponds through the wire respectively, and every fuse passes through the wire and links to each other rather than the pilot lamp that corresponds respectively, and a N line is drawn forth after every pilot lamp end passes through the wire short circuit in proper order, and another N line is drawn forth through another wire to first pilot lamp end, and every N line connects to main N row.

Further, the wires are sequentially short-circuited to form a loop.

Furthermore, the wiring circuit is suitable for a high-low voltage switch cabinet with multiple loops sharing N lines or multiple loops sharing PE lines.

The utility model discloses beneficial effect does: the utility model relates to a novel low-voltage switchgear secondary zero line ground wire circuit of working a telephone switchboard, through the zero (ground) line short circuit in a plurality of return circuits, first and last zero (ground) line draw out respectively to main zero (ground) row's mode, both reached the effect that zero (ground) line is reliable and main zero (ground) row is connected, the amount of drawing forth of wire has also been practiced thrift simultaneously, the advantage of this kind of mode of working a telephone switchboard lies in, the zero (ground) line in a plurality of return circuits has the short wire or virtual other corresponding zero (ground) lines in the circumstances of connecing of arbitrary a plurality of return circuits to throw away can be reliable and main zero (ground) row is connected, make the wiring safe, beautifully, it is horizontal vertical simple and clear. No matter how many the number of the secondary zero (ground) lines, only two cables need to be led to the zero (ground) row, the utility model discloses safe and reliable does benefit to popularization and application.

Detailed Description

As shown in the figure, the utility model relates to a novel high-low voltage switch cabinet secondary zero line ground wire wiring circuit, including power A, wire B, fuse C, pilot lamp D and N line (zero line) E, the number of power, fuse and pilot lamp is the same, is 5, vertical one-to-one, and every power links to each other through the fuse that the wire corresponds rather than respectively, and every fuse passes through the wire and links to each other rather than the pilot lamp that corresponds respectively, and every pilot lamp is terminal to draw forth a N line through the wire after the wire short circuit in proper order, and the wire short circuit forms the return circuit in proper order. And another N line is led out from the tail end of the first indicator light through another wire, and the two N lines are connected to the main N row, so that no matter how many secondary zero (ground) lines are, only two cables need to be led to the zero (ground) row.
