Abstract
The utility model discloses a non-injection inductive coupler, which comprises two semicircular amorphous microlite alloy magnetic cores, which can be enclosed outside a power supply cable or a ground wire of a power supply cable after being combined; an annular stainless steel anchor ear which is connected with a locking device and is fixed on the exterior circumference of the annular amorphous microlite alloy magnetic cores; an induction coil winding consisting of a plurality of turns of coils enwound on the amorphous microlite alloy magnetic cores and the stainless steel anchor ear. The locking device connected with the stainless steel anchor ear consists of a dropper, a duckbill and adjustable nuts. The non-injection inductive coupler provided by the utility model makes use of the amorphous microlite alloy magnetic cores and the induction coils enclosed outside shielding layers of power supply cables or ground wires of power supply cables to transmit signal. To destroy structure of original cables or ground wires of cables is not required. In addition, the utility model has compact conformation, is very convenient to be mounted and is very flexible.
Description
Technical field
The utility model relates to a kind of inductive coupler, particularly relates to a kind of non-pouring-in inductive coupler that uses in the high voltage transmission line carrier communication system that is applicable to.
Background technology
Inductive coupler is the important Coupling device that uses in a kind of high voltage transmission line carrier communication system, it can be installed in the no current potential screen or earth bus loop of power cable, send or receive the power line carrier signal by high frequency cable, realize impedance matching between transmission channel and the power line carrier equipment and the isolation between high-tension apparatus and the power line carrier equipment, and the transmission that can be the power line carrier signal provides very little insertion decay.Chinese patent 02237823.5 by the applicant's application and mandate discloses a kind of like this inductive coupler.Advantages such as this inductive coupler has that operating frequency is wide, signal attenuation is little, rated current is big, installation is convenient, easily debugging and signal transmission be unobstructed, thereby obtained using widely.During installation its upper port is linked to each other with cable shield, its lower port is then joined with earth connection.But we find that the space is narrower and small in some regional box type transformer in installing at the scene, thereby can't assemble this inductive coupler, thereby bring many inconvenience to installment work.And do not see as yet on the domestic market at present any need not to link to each other with power line can finish also that signal sends and the inductive coupler of reception.
Summary of the invention
In order to address the above problem, the purpose of this utility model is to provide a kind of compact conformation, easy for installation and flexible, and lower-cost non-pouring-in inductive coupler.
In order to achieve the above object, the non-pouring-in inductive coupler that provides of the utility model can be enclosed within power cable or the outer semicircle amorphous microcrystalline alloy magnetic core of power cable earth connection after comprising two merging; Link to each other with locking device and be fixed on ring stainless steel anchor ear on the annular amorphous microcrystalline alloy magnetic core excircle; Be wrapped on amorphous microcrystalline alloy magnetic core and the stainless steel anchor ear ring a few, and the induction coil winding that links to each other with carrier terminal equipment of two exits.
The described locking device that links to each other with the stainless steel anchor ear is made up of hook, duckbilled and adjustable nut.
The non-pouring-in inductive coupler that the utility model provides is to utilize amorphous microcrystalline alloy magnetic core that is enclosed within power cable or power cable earth connection screen outside and the transmission that induction coil is realized signal, it need not to destroy the structure of original cable or cable grounding line, and compact conformation, install very convenient and relatively flexibly.
Description of drawings
Below in conjunction with the drawings and specific embodiments non-pouring-in inductive coupler of the present utility model is elaborated.
Fig. 1 is a non-pouring-in inductive coupler vertical view of the present utility model.
Fig. 2 is a non-pouring-in inductive coupler front view of the present utility model.
Fig. 3 and Fig. 4 are respectively non-pouring-in inductive coupler of the present utility model and are installed in user mode figure on power cable or the power cable earth connection.
Embodiment
As shown in Figures 1 to 4, the non-pouring-in inductive coupler that provides of the utility model can be enclosed within power cable I or the outer semicircle amorphous microcrystalline alloy magnetic core 1 of power cable earth connection II after comprising two merging; Link to each other with locking device 4 and be fixed on ring stainless steel anchor ear 2 on annular amorphous microcrystalline alloy magnetic core 1 excircle; Be wrapped in amorphous microcrystalline alloy magnetic core 1 and stainless steel anchor ear 2 rings and go up a few, and the induction coil winding 3 that links to each other with carrier terminal equipment V of two exits.The described locking device 4 that links to each other with stainless steel anchor ear 2 is made up of hook 5, duckbilled 6 and adjustable nut 7.What magnetic core in the non-pouring-in inductive coupler that the utility model provides adopted is the amorphous microcrystalline alloy material of excellent performance, thereby every performance index of product are improved and improves.In addition, the size of this inductive coupler is less, thereby required material is less, thereby can reduce cost.Only need during installation locking device 4 is opened, two semicircle amorphous microcrystalline alloy magnetic cores are enclosed within the outside of power cable I or power cable earth connection II, hook 5 is linked to each other with duckbilled 6, and tighten adjustable nut 7, at last two exits of induction coil winding 3 are linked to each other with carrier terminal equipment V and can carry out the signal transmission, not only installation is very simple, but also can not destroy the facility on the high voltage transmission line.
With reference to IEC61334-3-22:2001 " middle pressure phase ground and pouring-in shielding ground bonding apparatus " standard non-pouring-in inductive coupler of the present utility model is tested, its key technical indexes is as follows:
Operating frequency 60-150KHz
Nominal impedance 75 Ω
Transmission range max 5km
This shows that the non-pouring-in inductive coupler that the utility model provides can satisfy the requirement of the PLC communication technology fully.
