DAHU electrical specializes in the production of 0.5-40.5kv transformers. It has cooperated with many national power bureaus for 10 years and exported to foreign markets. If there is any quality problem within the warranty period, it can be replaced free of charge.
Strut mounted high voltage voltage transformers (VT or PT) are key devices used in power systems to convert high voltages to low voltages for measurement, protection and control applications. Here is some key information about strut type high voltage voltage transformers:
Principle of operation:
Voltage transformers (VT or PT) work based on the principle of electromagnetic induction, converting the voltage on the high voltage side proportionally to the voltage on the low voltage side by means of an iron core and coil for use in measuring instruments and relay protection devices
Voltage transformer (VT or PT) works based on the principle of electromagnetic induction.
Technical parameters:
Technical parameters include rated voltage, ratio, accuracy class, frequency range and rated current. Rated voltage ratio is the key parameter, which determines the voltage relationship between the primary side and secondary side of the transformer.
The rated voltage ratio is the key parameter that determines the voltage relationship between the primary and secondary sides of the transformer.
Classification:
According to the voltage transformation principle is divided into electromagnetic and capacitive voltage divider. Electromagnetic induction type is mostly used for 220kV and below various voltage levels; capacitive voltage divider type is generally used for power systems above 110kV.
Classification.
Application Scenario:
Pillar-type high-voltage voltage transformer is suitable for indoor type of 35kV and below and outdoor type of 35kV and above power distribution equipment.
Application Scenario.
Insulation method:
Can be divided into dry type, casting type, oil-immersed type and gas-filled type. Pouring type voltage transformer structure is compact, easy maintenance, suitable for 3kV ~ 35kV indoor distribution equipment; oil-immersed voltage transformer insulation performance is better, can be used for more than 10kV outdoor power distribution equipment.
The oil-immersed voltage transformer has good insulation performance and can be used in outdoor distribution equipment above 10kV.
Product Features:
Certain high-voltage voltage transformers are encapsulated with epoxy resin, have high dielectric strength and insulation resistance, can withstand shock voltage, and have a wide range of operating frequencies.
.
Accuracy Class:
The accuracy class conforms to IEC 60044-2 standard, including 0.01, 0.02, 0.05 class, which ensures the accuracy of voltage transformer measurement under various working conditions.
The
Environmental Protection Requirements:
Comply with RoHS environmental requirements, indicating that the product in the selection of materials and production process to take into account the environmental factors
.
Installation and Design:
Capacitive voltage transformers (CVTs) are designed for tariff metering and protection of high-voltage power grids, with a single-phase design intended to connect the phase and ground of a network with an insulated or directly grounded neutral point
.
Pillar type high voltage voltage transformers are an integral part of the power system, they ensure stable operation and safe protection of the power system
