Here is some key information about the LAJ-10Q Authentic Cast Insulation Totally Closed Through-Wall High Voltage Current Transformer (CT):
Product Overview:
LAJ-10Q type current transformer is a through-the-wall epoxy resin casting insulation products, suitable for rated frequency of 50Hz or 60Hz, rated voltage of 10kV and below in the power system, for power metering, current measurement and relay protection
It is suitable for power measurement, current measurement and relay protection in power systems with rated frequency or rated voltage of 10kV and below.
Technical Parameters:
Rated insulation level: 12/42/75kV (under the condition of surface condensation and artificial class II filth).
Power factor of load: COSφ=0.8 (lagging).
Rated secondary current: 5A.
Product performance in line with the standard: GB/T20840.1 and GB/T20840.2
.
Structural features:
The transformer is epoxy resin casting reinforced insulation type, which can be used in humid, product surface condensation and tropical and plateau areas.
250A and below is a multi-turn fully enclosed cast structure, 300-1000A is a single-turn fully enclosed cast structure, which enhances the strength of the external insulation, and belongs to the working condition type products.
It is a working condition type product.
Application conditions:
Ambient temperature: indoor type between -5ºC~+40ºC; outdoor type between -25ºC~40ºC, the average daily temperature does not exceed 30ºC.
Relative humidity not more than 85%.
Altitude not exceeding 1000m
.
Rated output and short-time thermal current, dynamic stabilization current:
The specific rated primary current, accuracy level and corresponding values of rated output, short-time thermal current and dynamic stabilizing current are shown in the following table:
| Rated Primary Current (A) | Accuracy Level Combination | Rated Output (VA) | Short-Time Thermal Current (kA) | Dynamic Stabilizing Current (kA) |
|----------------|------------|------------|--------------|--------------|
| 20/5 | 0.2S/0.5 | 10 | 2.4 | 4.3 |
| 30/5 | | | | | | | | | | | | | | | |
| ... | | | | | | | | |
