VI. Frequently Asked Questions (FAQ) for 160kva Transformers
Ⅰ What are the typical application scenarios of 160kva three-phase oil immersed transformers?
*Power distribution for small and medium-sized factories;
*Electricity supply for commercial buildings, hospitals, or schools;
*Voltage conversion of rural power grids or community distribution systems;
*Power distribution at temporary construction sites.
Ⅱ What are the common configurations for its rated input/output voltage?
*High voltage side: 10kV (domestic distribution standard);
*Low voltage side: 400V (three-phase four wire system, line voltage 400V/phase voltage 230V);
Ⅲ How to calculate its rated current?
*High voltage side: I=160kva/10kV/√3=9.24A
*Low voltage side: I=160kva/0.4kV/√3=230.94A
Ⅳ What are the requirements for the surrounding environment during installation?
*Good ventilation, keep away from flammable and explosive materials;
*The basic platform needs to be level and load-bearing (with an oil content of about 200kg);
*Reserved heat dissipation space (with a side distance of ≥ 0.8 meters from the wall and no obstruction at the top);
*Outdoor installation requires the installation of rain covers or fences.
Ⅴ What is the overload capacity of a 160kva transformer?
*Short term overload (such as within 2 hours) can reach 150% load (copper coil);
*Long term overload will accelerate insulation aging, and it is necessary to avoid operating beyond the rated capacity.
Ⅵ What are the key points to pay attention to in daily maintenance?
*Oil level check: The oil gauge of the oil pillow should be within the marked range;
*Oil temperature monitoring: During normal operation, the top oil temperature is ≤ 65 ° C;
*Leakage inspection: Check for oil leakage in the fuel tank welds and gaskets;
*Regular tests: insulation oil withstand voltage test, winding DC resistance measurement (once a year).
Ⅶ How to determine whether insulation oil needs to be replaced?
*Breakdown voltage: below 30kV (new oil standard ≥ 35kV);
*Excessive acid value:> 0.1mg KOH/g；
*High moisture content:> 20ppm；
*Oil color dark black or with carbide particles (needs to be filtered or oil changed).
*Reason: Overload, blocked radiator, oil circulation failure, internal winding short circuit;
*Solution: Immediately reduce the load and check the load; Clean the heat sink or repair the cooling system; Suspend maintenance for internal faults.
Ⅸ What protective devices must be configured?
*High voltage side: drop out fuse or circuit breaker (overcurrent protection);
*Low voltage side: air switch (short circuit protection);
*Body protection: gas relay, pressure relief valve, thermometer;
*System protection: lightning arrester (lightning protection), grounding device (grounding resistance ≤ 4 Ω).
Ⅹ How to choose energy efficiency level when purchasing?
*Standard: According to local national energy efficiency regulations or customer requirements
