Abstract
A kind of pouring-in coupler for ring network cabinet communication, is respectively connected to cable shield end and earthing bar for side terminal of coupler in installation process, and realization concatenates coupler into shielding layer grounding line.The fixing terminal of coupler is fixed by bandage or screw.Secondary side signal terminal is connect with ring network cabinet communication module using high-frequency signal line.The pouring-in coupler structure of the utility model is compact, communication is stablized, and fully meets ring network cabinet communication requirement.
Description
Technical field
The utility model relates to a kind of pouring-in couplers for ring network cabinet communication, especially lead with power distribution automation
Cable shield makees the pouring-in coupler of the ring network cabinet communication of communication media in domain.
Background technique
Coupler is the Coupling device used in ring network cabinet communication system, main function be by coupling communication signals extremely
Cable shield realizes the communication between communication module, completes impedance matching between communication module and cable shield and is right
It is isolated between cable side and secondary ring network cabinet communication module data side.The coupler is good, logical in electrical safety performance
Believe that performance is stablized, can adapt to the communication signal transmissions under high and low temperature environment, meets the ring network cabinet communication of distribution automation field
Demand.Currently, domestic main coupler majority is plug-in coupler, the decaying of the type product signal is big, communication performance is poor,
This power distribution automation communication channel high to reliability requirement brings great hidden danger.
Utility model content
To solve the problems, such as that the application of plug-in coupler, the utility model provide a kind of installation side in ring network cabinet communication
Just, quick construction can guarantee the pouring-in coupler of the reliable and stable operation of ring network cabinet communication system.It is provided by the utility model
Pouring-in coupler for ring network cabinet communication is primarily characterized in that:
(1) primary side is the ground connection annealed copper wire for meeting domestic medium-voltage distribution circuit ground line code requirement, is grounded annealed copper wire
There are two tainless terminals, and one end is connected with cable shielding layer earthing line during the installation process, and the other end is crimped to ring network cabinet
On earthing bar.The mounting means is pouring-in installation, therefore the coupler is known as pouring-in coupler.
(2) secondary side is connected to ring network cabinet communication module by high-frequency signal line, realizes signal transmission.
(3) coupler ontology is the shell that circular configuration pours, and site operation is facilitated to install.
The utility model proposes coupler be pouring-in installation, by concatenating coupler primary side to cable shield
Ground line, secondary side connect with ring network cabinet communication module, realizes that ring network cabinet communication module couples a signal to cable shield.
Compared with plug-in coupler, communication performance is more excellent, and system operation is more reliable.
Detailed description of the invention
Coupler appearance and mounting means are described in detail in conjunction with attached drawing.
Fig. 1 is the top view of the pouring-in coupler of the utility model.
Fig. 2 is the installation method of the pouring-in coupler of the utility model.
Specific embodiment
As shown in Figure 1,1 once flanks shielded layer terminal for pouring-in coupler, 2 be the primary side of pouring-in coupler
Ground terminal, 3 be the secondary side signal terminal of coupler, and 4 be the body construction of coupler, and 5 be the fixing terminal of coupler.This
The pouring-in coupler of utility model during the installation process, is connected with cable shield by once shielded layer terminal 1 is flanked, passes through
Screw is by terminal and shielding layer grounding wire crimp；The primary side ground terminal 2 of coupler is connected with earthing bar again, and will bridging
Ground line between terminal 1 and 2 is cut；Secondary side signal terminal 3 is connect with ring network cabinet communication module with high-frequency signal line；
The fixing terminal 5 of coupler is fixed using bandage or screw.
The above description is only the embodiments of the present invention, and therefore it does not limit the scope of the patent of the utility model, all
Equivalent structure or equivalent flow shift made based on the specification and figures of the utility model, is applied directly or indirectly in
Other related technical areas are also included in the patent protection scope of the utility model.
Claims (1)
1. a kind of pouring-in coupler for ring network cabinet communication, the ring network cabinet for distribution cable route is communicated, and is mainly tied
Structure is made of first siding ring, second siding ring and coupler ontology；For cable run application characteristic, by the primary of coupler
The both ends of lateral coil are connected on the shielded layer side of cable and the earthing bar of ring network cabinet position, realize the note of coupler
Enter formula installation；The signal terminal of secondary side is connected to ring network cabinet communication module, the primary side of coupler, two by high-frequency signal line
Secondary side realizes the high-voltage line trackside of distribution system and the isolation of low-voltage signal side.
