LXK-80 High-voltage zero sequence transformer indoor casting opening and closing through-type core protection device
Product Overview:
LXK-80 series zero sequence current transformer is suitable for indoor, rated frequency 50Hz or 60Hz, rated voltage 10KV below the power system in three-phase AC generator, motor zero sequence current protection.
The product is unsaturated epoxy resin casting open and close structure, convenient for product installation; magnetic conductivity materials used by the annealed toroidal iron core, to ensure that in the primary zero sequence current reaches the set current, the secondary accurate output current for relay action to achieve the purpose of protection.
Technical parameters:
Bore diameter of 80mm, suitable for cable through-center structure, only the insulation of the secondary coil is considered, the secondary coil to ground frequency withstand voltage 3kV
The secondary coil has a working frequency withstand voltage of 3kV to ground.
The installation place is indoor, the ambient temperature is maximum +40ºC, minimum -5ºC, the altitude does not exceed 1000m, no serious dirt in the atmosphere.
.
Structural characteristics:
Adopting "C" type iron core, the secondary coil is wound in two parts on the "C" type iron core and molded by epoxy resin casting. There are clamps at the bottom of the product for installation and fixing.
The bottom of the product has a clip for installation and fixing.
LSY-10 transformer protection device
Product description:
LSY-10 three-phase integrated current transformer is suitable for installation on the three-phase casing of ring network switchgear and main column switch, used for the measurement and protection of three-phase current transformer and zero-sequence current, and can also be used for the measurement and protection of zero-sequence current of multiple cable circuits.
It can also be used for zero sequence current measurement and protection of multiple cable circuits.
The core and secondary winding of this series of zero sequence current transformers are vacuum-wound with high quality epoxy resin in a flame-retardant plastic shell, which is moisture-proof, stable in performance and maintenance-free.
The core and secondary winding are made of high quality epoxy resin vacuum-wound in a flame retardant plastic case.
