Product DescriptionJSZWK-10 anti-vibration three-phase voltage
transformer is mainly insulated by epoxy resin and special
insulating materials. It is equipped with a protective iron
box and a porcelain sleeve, which improves the moisture-proof
performance and electrical insulation performance. This product is
not afraid of frequency division, high frequency, It will be
burnt due to overvoltage, and it can run in the case of
single-phase grounding of the line for a long time without
over-temperature concerns. At the same time, the protection
winding generates a voltage of 100V to drive the relay to work.This
type of voltage transformer is a new type of voltage transformer
developed and developed after the three-phase five-column
voltage transformer to eliminate the public nuisance of
ferromagnetic resonance and a large number of burnt out of
the transformer due to the grounding of the power system to
different degrees.Model DescriptionTechinical parameters and
Structure dimensionsProduct features and scope of useThe high
voltage is converted into a standard secondary voltage of 100V or
lower according to a proportional relationship, which is used
for protection, metering and instrumentation devices. At the same
time, the use of voltage transformers can isolate high
voltages from electrical workers. Although the voltage transformer
is also a device that works according to the principle of
electromagnetic induction, its electromagnetic structure
relationship is exactly opposite to that of the current
transformer. The secondary circuit of the voltage transformer
is a high-impedance circuit, and the magnitude of the
secondary current is determined by the impedance of the circuit.
When the secondary load impedance decreases, the secondary
current increases, so that the primary current automatically
increases a component to satisfy the electromagnetic balance
relationship between the primary and secondary sides. It can
be said that the voltage transformer is a special transformer with
limited structure and use form. Simply put, it is the
"detection element".Use environment: 1. Installation
location: outdoor; 2. Ambient temperature: -25ºC ~ +60ºC;3.
Altitude: the altitude of the installation site should not exceed
2000 meters; 4. Relative humidity: the daily average is not
more than 95%, the monthly average is not more than 90%; 5.
The wind pressure does not exceed 700Pa (equivalent to a wind speed
of 34m/s); 6. Pollution level: 3Ordering notice1. Provide
wiring scheme diagram, application and system diagram, rated
voltage, rated current, etc.2. Requirements for control,
measurement and protection functions and other locking and
automatic devices.3. When the transformer is used in special
environmental conditions, it should be explained in detail when
ordering.4. When other or more accessories and spare parts are
needed, the type and quantity should be proposed.Product
