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.
Here is some key information about LXK-80~240 zero sequence toroidal current transformer:
Product Overview:
LXK-80 ~ 240 type zero sequence toroidal current transformer is suitable for indoor, rated frequency 50Hz or 60Hz, rated voltage 35kV and below small grounding current system, for three-phase cable grounding protection, can also be used with relay protection matching
It can also be used with relay protection.
Technical parameters:
The primary insulation of the current transformer is ensured by the cable, the product only assesses the insulation of the secondary winding, the secondary winding can withstand 3kV frequency withstand voltage to ground.
The secondary winding can withstand 3kV frequency withstand voltage to ground.
The rated current ratio, accuracy level and rated output are shown in the following table (LXK-Φ(80, 120) type for example):
Ratio (A) | Relay Model | Relay Coil Link Type | Relay Scale | Primary Residual Current to Operate Relay (A) | Weight (kg)
60/1 | DD-11/60 | Series | 15×1 | 2.4-4.5 | 4.5
30×1 | | Parallel | 15×2 | 3-5 | DD-1/60 | Tandem | 3-4.5 | 4.5
DD-1/60 | Tandem | 15×1 | | 3-5 | 30×1 | Parallel | 15×2 | 3-5 | 30×1 | Parallel
30×1 | parallel | 15×2 | | 3-6 | DD-1/60 | series | 15×1 | | 3-5 | DD-1/60
Higher ratios and accuracy levels are also available, see brochure or contact manufacturer.
See brochure or contact manufacturer.
Product Features:
The transformer can be divided into two halves for installation, then combined into a single unit and clamped tightly with a hoop. Installation can be carried out without power supply.
The series of zero sequence current transformers are made of high quality materials.
The series of zero sequence current transformer imported high-quality silicon steel sheet processed by a special process into a toroidal core, with high accuracy and accuracy limitation coefficient, the core and the secondary winding using high-quality epoxy resin vacuum cast in a flame retardant plastic shell, moisture-proof, stable performance, no maintenance, its small size, light weight, small footprint.
.
Application scope:
Suitable for AC power systems, distribution lines and AC generators, motors and other electrical equipment, zero sequence overcurrent protection and small current grounding and routing devices, through the cable aperture range φ100mm ~ φ240mm
The aperture range of cable penetration is φ100mm~φ240mm.
The above information provides detailed technical parameters and product features of LXK-80~240 type zero sequence toroidal current transformer for your reference.
