Product Description

Current Transformer Temperature Rise Testing Machine CT Thermal Rise Automation Test Device

Product Introduction

GDCW current transformer temperature rise automation test device in accordance with the national grid standard <<GB1206 current transformer>> and the State Grid Corporation standard <<Q/GDW1572 metering current transformer technical specifications>> and other requirements to complete the current transformer temperature rise detection test fully automatically. According to the rated current size of the connected current transformer, the device automatically controls the electronic booster to rise to the target test current required by the standard, and in the process uninterruptedly monitors the temperature of the body of the current transformer, the temperature of the winding joints, the ambient temperature, etc., and automatically determines whether the current transformer has reached thermal stability on the basis of the measured temperature value and the standard requirement of the temperature rise stability conditions. When the temperature rise of the current transformer has reached stability, the device measures the DC resistance of the current transformer coil, and calculates the maximum temperature of the coil winding resistance after the current transformer has reached thermal stability and the maximum temperature rise during the test based on the winding resistance at this time and the DC resistance of the coil winding before the current rise.

Product Advantages
 

Compared with the current manual measurement of current transformer temperature rise test device has the following obvious advantages:

1.GDCW current transformer temperature rise automation test device can simultaneously measure the temperature rise of 5 current transformers, test efficiency is greatly improved.

2. Automatic adjustment of the output current size during the test, so that the test current and the target current error is always less than 0.5%, will not be due to changes in the resistance of the main circuit, grid voltage fluctuations and other factors causing large fluctuations in the test current, so that the test process is more convincing.

3. Real-time monitoring and recording of the temperature of the current transformer body, winding resistance joints and the environment, and automatically determine the temperature rise of the current transformer thermal stability conditions, to avoid errors in human judgement.

4 current transformer to achieve thermal stability, rapid measurement of current transformer winding resistance, to avoid manual wiring test time delay caused by the temperature rise value measurement error.

5 automatic switching of the current transformer secondary circuit load, to avoid possible errors caused by manual operation.
