Abstract
A sleeve of a distribution transformer comprises a sleeve body, wherein a pressing block is arranged on the sleeve body, and a rubber ring is arranged between the sleeve body and the pressing block. The sleeve of the distribution transformer is characterized in that the sleeve body is made of insulation silicon rubber, a magneto-electric inductor is arranged in the sleeve body in embedding mode, and a lead end of the magneto-electric inductor is guided out of the sleeve body. The sleeve of the distribution transformer has the advantages that the installation process is easier and more convenient due to the fact that no additional current inductors are needed to be installed, and simultaneously the problem of large measurement error rate caused by installation process level is solved due to the fact that the position of the magneto-electric inductor in the sleeve body is fixed. In addition, the sleeve body can protect the magneto-electric inductor so that failure rate of measurement devices is reduced and service life of the measurement devices is long. The sleeve body is good in insulation performance due to adoption of insulation silicon rubber, and simultaneously effect on the magneto-electric inductor caused by the insulation silicon rubber is weak due to the fact that the insulation silicon rubber is small in interior stress.
Description
Technical field
The present invention relates to a kind of sleeve of distribution transformer.
Background technology
On near wire in distribution line sleeve of distribution transformer, measuring equipment is installed, described measuring equipment is made up of coil current instrument transformer, gauge table, coil current instrument transformer wherein utilizes the voltage signal in electromagnetic induction principle measuring transformer output circuit, and voltage signal is transferred to gauge table.Be subject to the impact of the performance difference of instrument transformer own and mounting process level, the error rate of this metering method is large, and the failure rate of measuring equipment is high.Existing sleeve of distribution transformer comprises sleeve body, is provided with briquetting in sleeve body, between sleeve body and briquetting, is provided with cushion rubber.The material of sleeve body is ceramic insulating material, and insulation property can not satisfy the demands; In addition, sleeve of distribution transformer is only for drawing transformer binding post, function singleness.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of voltage signal that can gather in transformer output circuit, improves the failure rate of sleeve of distribution transformer insulation property, reduction metering device, the sleeve of distribution transformer of raising gauge table metering accuracy.
The present invention is achieved in that
A kind of sleeve of distribution transformer, comprise sleeve body, in sleeve body, be provided with briquetting, between sleeve body and briquetting, be provided with cushion rubber, its special character is: the material of described sleeve body is electrically insulating silicone rubber, in sleeve body, be embedded with magnetoelectric induction device, the lead end of described magnetoelectric induction device is drawn by sleeve body.
Above-mentioned magnetoelectric induction device is one.
Above-mentioned magnetoelectric induction device is multiple along the circumferential direction uniform, and is drawn by sleeve body after the lead end parallel connection of each magnetoelectric induction device.
The invention has the beneficial effects as follows:
Magnetoelectric induction device is embedded in sleeve body, and without current transformer is installed separately, installation process is easier; Meanwhile, because the position of magnetoelectric induction device in sleeve body fixed, avoided the large problem of error in dipping rate causing because of mounting process level; In addition, sleeve body can provide protection for magnetoelectric induction device, and the failure rate of measuring equipment reduces, long service life; The material of sleeve body is electrically insulating silicone rubber, good insulation preformance, and meanwhile, electrically insulating silicone rubber internal stress is little, a little less than the impact of magnetoelectric induction device.
