Description

Inlet wire plug assembly of intelligent switch cabinet

Technical Field

The utility model relates to the technical field of power distribution cabinets, in particular to an incoming line plug assembly of an intelligent switch cabinet.

Background

In the drawer of an intelligent switch cabinet, a circuit breaker and a detection unit of the circuit breaker are generally integrated, a wire inlet end of the circuit breaker is connected to a bidirectional socket of a distribution bus through a wire inlet plug, a wire outlet end of the circuit breaker is connected to a wire outlet plug through a copper bar, and the part forms a primary circuit of the drawer. Detection units are then typically integrated on the primary circuit, which include at least a voltage sensor, a current sensor and a temperature sensor for detecting the current, voltage and temperature of the primary circuit.

In these detection units, the current sensor and the voltage sensor are generally arranged in a substantial range, such as between the circuit breaker and the incoming plug, and between the circuit breaker and the outgoing plug, from the viewpoint of easy maintenance. However, such an arrangement inevitably results in that the signal lines of the voltage sensor, the current sensor and the temperature sensor are relatively close to each other and are easily crossed together, so that on the one hand, the signal lines are inconvenient to be regulated, and on the other hand, the current signals in the signal lines of the current sensor easily cause crosstalk to the voltage signals in the signal lines of the voltage sensor. For example, on the conductive posts connected with the a/B/C three-phase interface of the inlet terminal of the circuit breaker, 3 kinds of sensors are distributed, so that the signal wire of the voltage sensor on any conductive post is affected by the current sensor on the same conductive post and the current sensor on the adjacent conductive post.

Disclosure of Invention

The summary of the utility model is provided to introduce a selection of concepts in a simplified form that are further described below in the detailed description. The summary of the utility model is not intended to identify key features or essential features of the claimed subject matter, nor is it intended to be used to limit the scope of the claimed subject matter.

In order to solve the problem of serious crosstalk of signal lines in drawers, some embodiments of the present utility model provide an incoming line plug assembly of an intelligent switch cabinet, including:

a conductive post for connection to a distribution busbar;

a connection post connected to the circuit breaker;

a connection conductor having one end connected to the conductive post and the other end connected to the connection post such that the conductive post is connected to the circuit breaker;

the arrangement direction of the conductive columns is perpendicular to the arrangement direction of the connecting columns, and the first sensors are arranged on the conductive columns; a second sensor is disposed on the connection post.

In this solution, the first sensor and the second sensor are both arranged between the circuit breaker and the distribution busbar, so that these sensors are approximately in a relatively concentrated area, which is relatively simple to overhaul. Meanwhile, the second sensor is disposed on the connection post, the first sensor is disposed on the conductive post, and the arrangement directions of the connection post and the conductive post are not parallel to each other, so the arrangement directions of the first sensor and the second sensor are not parallel to each other, but are not disposed along the same direction. The signal lines of the first sensor and the signal lines of the second sensor intersect with each other at a small number of portions and are distant from each other.

Further, the arrangement direction of the conductive posts is perpendicular to the arrangement direction of the connecting posts.

The arrangement direction of the connecting posts and the arrangement direction of the conductive posts are mutually perpendicular, and the circuit breaker is more suitable for the position relation between the circuit breaker and the distribution wiring. Because the distribution buses are generally vertically arranged in the cabinet body, the A, B, C three phases of the distribution buses are transversely arranged at intervals. After the circuit breaker is arranged in the drawer, A, B, C three-phase interfaces of the wire inlet end of the circuit breaker are generally longitudinally arranged, so that the wire inlet end arrangement mode of the circuit breaker and the distribution bus are generally vertically arranged; therefore, in the scheme, the arrangement mode of the conductive column and the connecting column can be more suitable for the position relation between the distribution bus and the circuit breaker.

Further, the device further comprises a fixing plate, at least one of the connecting column and the guide column penetrates through the fixing plate, and a plurality of mutually parallel protrusions are arranged on the fixing plate. The signal lines can be arranged along the projections by the projections provided on the fixing plate so as to separate the signal lines of the first sensor and the second sensor.

Further, a plurality of notches are also arranged on the protrusions. The notch can be passed to the ribbon, then behind ribbon end to end, fixes the signal line on protruding, avoids the signal line to be scattered, so set up the notch, can be convenient for fix the signal line on protruding through the ribbon.

Further, the extending direction of the protrusions is parallel to the arrangement direction of the conductive posts, and the arrangement direction of the protrusions is perpendicular to the arrangement direction of the conductive posts.

So, a plurality of archs will set up in the one side of spliced pole side by side, and then the signal line of the second sensor on the spliced pole of difference can be arranged along different archs respectively, and the signal line to the second sensor that can be better is regular to, because the signal line of every sensor can be arranged along different archs respectively, so be difficult to confuse the signal line of second sensor when overhauing.

Further, the second sensor is a milliamp-level induction coil.

The milliamp-level induction coil is capable of detecting current information and is smaller in volume than the remaining induction coils so that it can be disposed on the connection post; meanwhile, compared with other types of sensors (voltage and temperature), the current information of 56mA passing through the signal wire of the milliamp-level induction coil has the largest current, so that the signal wire is arranged by arranging the protrusions independently, and the crosstalk to signals transmitted in the signal wires of the other sensors can be avoided to the greatest extent.

Further, at least two conductive posts and at most one connecting post are arranged, and the central lines of the conductive posts and the connecting posts are mutually overlapped. Since the arrangement directions of the conductive posts and the connection posts are perpendicular to each other, the center lines of at most one of the conductive posts and the connection posts may coincide with each other. For example, when the positions of the bidirectional sockets of the phase a electricity of the distribution bus bar and the interfaces of the phase a electricity of the circuit breaker are just corresponding to each other and are positioned on the same straight line, the central lines for connecting the distribution bus bar, the connecting column and the conductive column are mutually overlapped.

The spacing between distribution buses is generally fixed. However, the distance between the connection posts is not necessarily the same for different types of molded case circuit breakers, so that the distance between the connection posts needs to be adjusted for different molded case circuit breakers. The utility model provides the following technical scheme:

further, at least one of the connecting column and the conductive column is in rotary connection with the connecting conductor; at least one of the connecting post and the conductive post forms a sliding connection with the connecting conductor.

Therefore, when the distance between the connecting columns is adjusted to adapt to the distances between the circuit breakers of different types, the angle and the length of the connecting line connected between the connecting columns and the conductive column are actually adjusted, and the connecting conductor can rotate and slide relatively, so that the angle and the length of the connecting conductor are adjustable, and the distance between the circuit breakers of different types is further adapted.

Further, a first guide structure is arranged on the connecting conductor, a second guide structure is formed on at least one of the connecting column and the conductive column, and the first guide structure and the second guide structure are in guide fit.

Further, the first guiding structure is a guiding groove arranged on the connecting conductor, and the second guiding structure is a guiding piece.

Further, the device also comprises a fixed housing, wherein a plurality of positioning holes are formed in the fixed housing, and positioning pins corresponding to the positioning holes are arranged on the connecting columns. The positioning pins on the connecting column are inserted into the positioning holes, so that the connecting column can be positioned, and different phases on the connecting column and the circuit breaker correspond to each other; because the conductive posts are all mutually corresponding to the distribution buses, the conductive posts are generally fixedly arranged. The connecting column is required to correspond to the circuit breakers of different types, so that the connecting column is required to move, and the position relationship among the connecting column, the connecting conductor and the conductive column is not changed after the connecting column is fixed through the matching of the positioning pin and the positioning hole.
