Introduction of Integrated Design of Distribution Transformer and Measuring Transformer
2017-05-02 16:33:36 click: 785The distribution transformer is an important equipment in the distribution network. At present, there are mainly the operation and management of the distribution transformer. Because the distribution of the distribution transformer is difficult to obtain the information in time, the long-term overload movement of the distribution transformer and the load type of the distribution transformer Many of the distribution network power quality has a greater impact and other issues. Distribution transformer intelligent monitoring system mainly by the distribution transformer monitoring terminal, data center. When the front distribution transformer is running, the high voltage side voltage is difficult to measure in the absence of a high pressure metering tank. In the conventional transformer structure, based on the high and low voltage leads to increase the current transformer, high pressure three, low voltage three, collecting current signal; high voltage coil internal measurement winding to achieve the voltage measurement, the equivalent of voltage transformer, Voltage signal; low pressure leads to copper openings, through the lead out.
Current transformers and voltage transformers, etc. are introduced into the electrical connector fixed to the wall of the box, through the electrical connector to the signal from the internal lead; cover placed thermometer to monitor the oil temperature.
S13-M · ZN-315/10 for the intelligent distribution network is S13-M · ZN-315/10, the connection group is Yyn0 and the voltage ratio is / 0.4% kV.
High and low voltage coil with special cardboard tube, the external winding without weft tape, the end of the coil are used to form the pressure ring, tap the area at the banding firmly, increase the coil strength; internal configuration measurement coil, the line voltage monitoring, line voltage Designed by 10000 / 400V.
In the body leads to the line, configure the high and low voltage current transformer, monitor the line current. High-voltage transformer parameters, low-voltage current transformer parameters, the transformer are made of amorphous materials, fully guarantee the accuracy of the measurement.
Configure the thermometer on the cover, monitor the oil temperature, and configure the platinum resistance on the intelligent module, and monitor the oil temperature with the thermometer.
The lid on the increase in electrical connectors, contacts and contacts between the full guarantee of electrical strength, the internal increase in sealed silicone to prevent oil leakage, through the connector to the current, voltage, temperature and other parameters passed to the intelligent module.
Transformer fuel tank with corrugated fuel tank, intelligent modules and electrical connectors outside the additional protective cover, small and beautiful appearance.
