Abstract
The invention relates to a current transformer capable of being started outdoors. The current transformer capable of being started outdoors comprises an upper semicircular iron core, a lower semicircular iron core, an upper outdoor semicircular resin shell and a lower outdoor semicircular resin shell, wherein a metal magnetism-conducting powder adhesive layer is arranged between the contact surface of the upper semicircular iron core and the contact surface of the lower semicircular iron core. According to the current transformer capable of being started outdoors, the metal magnetism-conducting powder adhesive layer is arranged between the contact surface of the upper semicircular iron core and the contact surface of the lower semicircular iron core, the upper semicircular iron core and the lower semicircular iron core are sealed through the upper outdoor semicircular resin shell and the lower outdoor semicircular resin shell, a wire to be tested penetrates through semicircular elastic rings on a central hole defined by the upper outdoor semicircular resin shell and lower outdoor semicircular resin shell in a connected and fixed mode, and then stable and high-precision use of the current transformer is achieved. The current transformer capable of being started outdoors is simple in structure, fast in installation, small in amount of leakage flux, high in measurement precision, good in partial discharging performance, resistant to aging, safe to use, and long in service life.
Description
Technical field
The present invention relates to current transformer, is the outdoor open-type current transformer of a kind of measurement and Microcomputer Protection specifically.
Background technology
Existing outdoor open-type current transformer is without line disconnection, two ferromagnetic cores that separate are snapped in after circuit fastening, but owing to being ferromagnetic core separately, fastening after between still exist air gap, thereby leakage field increases the certainty of measurement that has affected instrument transformer.In addition, outdoor open-type current transformer adopts in appearance and adds one deck sheath for protection at present, and while using under long-term adverse circumstances, sheath is easy aging and do not belong to identical material with instrument transformer appearance, affect instrument transformer and used safety and life-span, had potential safety hazard.
Summary of the invention
In order to solve above-mentioned deficiency of the prior art, the invention provides a kind of simple in structurely, quick for installation, leakage field is few, certainty of measurement is high, office put performance good, anti-aging, use safety, long outdoor open-type current transformer of life-span.
The technical solution used in the present invention is: a kind of outdoor open-type current transformer, comprise the unshakable in one's determination and upper and lower outdoor resin semicircle shell of upper and lower semicircle, and its technical characterstic is to be provided with metal magnetic conducting powdered adhesive layer between the contact-making surface of described upper and lower semicircle iron core.
Further, described upper and lower outdoor resin semicircle shell centre is to being connected into the interstitial hole that holds tested wire, on the circumference of interstitial hole, be evenly provided with three semicircle elastic rings that are connected in above on upper and lower outdoor resin semicircle shell, the center of circle of semicircle elastic ring and the center of circle of interstitial hole lay respectively at the both sides of semicircle elastic ring.
Again further, the bottom of described lower outdoor resin semicircle shell is provided with the stainless steel fixed base plate with fixed via.
Compared with prior art, advantage of the present invention is: adopt upper and lower outdoor resin semicircle shell to encapsulate upper and lower semicircle unshakable in one's determination, current transformer surface is without increasing safeguard procedures again, good weatherability, surface is without other materials, and it is excellent that performance is put in office, can meet various outdoor environment service conditions; The contact-making surface magnetic core surface of upper and lower two semicircular iron core is provided with metal magnetic conducting powdered adhesive layer, after zoarium, can fill the gap between upper and lower magnetic core, have advantages of that permeability is high, effectively avoided the leakage field that produces due to gap, increased the certainty of measurement of instrument transformer; In interstitial hole between upper and lower outdoor resin semicircle shell, all establish a plurality of semicircle elastic rings, semicircle elastic ring is fixedly connected with upper and lower outdoor resin semicircle shell, can be in advance in terrestrial operation, while having avoided installing in the past, first will fix and cushion equipment is fixed on punching circuit, reduced the danger of work high above the ground, play simultaneously and stablize the tested wire effect of cross-under; Stainless steel fixed base plate is fixed through fixed via by bolt, bears current transformer institute completely stressed, installs, easy to use, firm.
The present invention arranges metal magnetic conducting powdered adhesive layer between the contact-making surface of upper and lower semicircle iron core, by upper and lower outdoor resin semicircle shell, encapsulate upper and lower semicircle unshakable in one's determination, first the circular elastic ring of interstitial hole that coordinates upper and lower outdoor resin semicircle shell is the tested wire of cross-under fixedly, realizing stable, the high accuracy of current transformer uses, it is simple in structure, quick for installation, leakage field is few, certainty of measurement is high, office put performance good, anti-aging, use safety, life-span long.
