new type column type fully enclosed indoor high voltage current transformer LZZB7-35:
Product Overview:
LZZB7-35 type current transformer is epoxy resin casting, pillar type fully enclosed structure, suitable for rated voltage of 35KV and below, rated frequency of 50Hz or 60Hz indoor power system, for current, power measurement and relay protection.
It is suitable for current and power measurement and relay protection in indoor power system with rated voltage 35KV and below and rated frequency 50Hz or 60Hz.
Technical Parameters:
Rated insulation level: 40.5/95/185kV.
Partial discharge level in accordance with GB1208 "current transformer" standard.
Various combinations of accuracy levels, including 0.2/10P10, 0.5/10P10, 0.2/10P20, 0.5/10P20, etc. Rated output ranges from 30/50VA to 63VA, depending on the combination of accuracy levels.
.
Rated short-time thermal current (Ith) and rated dynamic stabilizing current (Idyn) also vary depending on the accuracy class combination.
.
Construction Features:
This series of products are electrical grade epoxy resin casting molding, fully enclosed structure, with small size, light weight, high insulation strength, moisture resistance, maintenance-free and so on.
The epoxy resin is made of German standard epoxy resin from foreign countries.
The epoxy resin adopts German standard foreign resin, full vacuum casting, so that the product has the characteristics of UV resistance, large creepage distance structure, condensation resistance.
The epoxy resin is made of foreign resin of German standard.
Adoption of superconducting magnetic material, so that the product can have a large dynamic and thermal stability of the current carrying capacity under high precision, small partial discharge.
The product is characterized by small partial discharges.
Use conditions:
Installation place: indoor.
Ambient temperature: -5ºC~+40ºC range, air humidity not more than 85%.
Altitude: 1000 meters below sea level for use.
Filth level: Class IV, no corrosive gas in the installation place
.
Working principle:
The current transformer works according to the principle of electromagnetic induction and consists of closed core and windings, with few turns in the primary winding and more turns in the secondary winding
The primary winding has few turns and the secondary winding has more turns.
