High Voltage Oil Immersed Transformer

Title goes here. INTRODUCTIONS I- GENERAL CHARACTERISTICS Transformers immersed in insulating fluid with natural self cooling (ONAN), three-phase, 10 - 20 MVA.for indoor or outdoor use, 50/60 Hz, hermetically sealed. II- MANUFACTURING STANDARD The transformers described in this catalogue are designedand tested in accordance to IEC/BSEN 60076 III- RATINGS 30,50, 80,100,125,160, 200,250, 315, 400, 500, 630, 800, 1000, 1250, 1600, 2000, 2500kVA. IV- HIGH VOLTAGE This material is designed for voltages of â?¤ 36 kV. Specific figures are not given for this parameter because of the wide variety of voltagesused. Transformers can be supplied on demand to run at two different primary voltages, the shift between these input voltages has two basic alternatives: with a primary tap changer which can be switched with no load and no applied voltage or by changing terminals under the cover. V- LOW VOLTAGE The secondary voltage under no load is allocated at 400V, 415V, 433V, though other voltages can be supplied on demand. When usage requires two voltages, transformers with two simultaneous voltages can be supplied. In this case the no-load voltages are set to 400V(230V),415V(240V),433V(230V). VI- VECTOR GROUP REFERENCE The connections normally used are as follows: For rated power levels of 160 kVA or less: Yyn0 For rated power levels over 160 kVA: Dyn11. ACCESSORIES I- BASIC EQUIPMENTS All transformers are supplied with: 3 high voltage bushings 4 or 7 low voltage bushings 5-position tap changer on cover, workable with transformer off load 2 lifting & tank removal eye-bolts Filling hole with M-40 x 1.5 outside thread and threaded cover Drainage & sampling plug at bottom of tank Two-way, standard rail gauge welded at the bottom of tank 2 earthing connections at bottom with M-10 screws II- OPTIONAL ACCESSORIES Thermometer Tap changer HV plug-in bushing Thermostat Protection & control block for the following

Pproduct brief introduction AC hipot tester series Testing Transformer is power plants power supply bureau and research institutions and other users to do the AC voltage test basic test equipment by the standards of the State Bureau of Quality Supervision for a variety of electrical products electrical components insulation material dielectric strength test etc. the insulation level assessment of products under the provisions of the voltage insulation defects were found in the sample and measure the ability of over-voltage. AC HV Testing Transformer Classification: There are four kinds of high voltage testing transformer according to the medium points: 1. Oil-immersed high voltage transformer test: large capacity cheap convenient maintenance mainstream products. 2. Inflatable high voltage test transformer : interrupter resistance and light weight. 3. Dry type high voltage testing transformer: light weight light volume can run backward price expensive. 4. Series type high voltage testing transformer: small volume low voltage light weight easy to transport and install.
