Product Description:

Type description

Technical characteristic
1.It accords to the GB1207-1997<voltage transformer> ,IEC186 and IEC60044.
2.This product has the character of limited tightness.All the tightness compartment do not be put into ultraviolet radiation so that we solve the problem of chap of tightness rubber and aging,these product is more reliable and has longer life,we ensure that it can run 20 years without leakage.
3.The porcelain is equipped with irragateing flange.the surface of flange use hot zincification to enhance the wholly mechnism of product and has beautiful outlook.
4.This product is equiped with bellow and is tightnesds completely.
5.With higher accuracy to 0.2,we can reach the requirment of customer with seperatly measuring secondary winding and protection winding.
6.With epoxy secondary terminal board,the product is enhanced secondary insulation and tightness.
7.All the standard comparthent are plated Dakelo.We ensure that the product don't rust for 20 years.
8.The inner structure of this product has changed largly and we solve the problem of old 35KV PT with unreasoned inner structure for the unpassed dielectric loss,This product has low partial discharge and litter dielectric loss with advanced workcraft.
9.The excitaton density of this product is equal or less than 0.7T and has the ability of avoiding ferro-resonance.

Q:The zero line of the transformer can be connected with the ground wire. Why not leave it?
Now the transformer, if the secondary side of the leakage protection, the user also received a leak, the zero line and ground must not be connected
Q:Inverter with transformer and transformer without the difference
Inverter with a transformer is played a role in isolation, it can provide you with pure sine wave current, so that the PV grid-connected system can provide a more secure and reliable isolation.
Q:How to use a multimeter to determine the quality of small transformers
Small transformer primary coil is generally 1 ~ 2k ohm, the secondary coil tens of ohms. If the problem with a multimeter measuring coil or open circuit, or open. There is also a fault that there is a short circuit in the middle of the coil, so that you only take the same transformer to compare the coil resistance.
Q:S11-1250kVA transformer oil capacity how much
S11-1250kVA transformer oil capacity is 550kg, the pressure of the relevant information will be marked on the nameplate, the nameplate has the relevant parameters.
Q:Altium designer DXP transformer in the same name how to change?
The same name is a painting of about 2-3mil radius of the solid circle, can not directly change, must be copied from the source file to the schematic library file can be changed, that is, to re-create schematic symbols.
Q:The difference between the reflection impedance of the ideal transformer and the hollow core transformer is different.
The reflection impedance of the hollow core transformer reflects the influence of the secondary circuit on the primary circuit through the mutual inductance. The reflection impedance is in series with the self-impedance of the primary circuit. The reflected impedance of the air-core transformer is opposite to the reactance characteristic of the secondary circuit impedance.
Q:80 kilowatts of electrical appliances need much transformer?
The selection of the transformer is based on the current. 80KW electrical current is 210A210 times (380 multiplied by 1.732) 138kva above the transformer can
Q:630 kilovolt transformer secondary side of the current is how much
There should be a second test voltage to calculate the current, but generally no load 400V. Full load 380V. Primary side rated current: I = 630000 ÷ 10000 ÷ 1.732 = 36.37A Secondary side rated current: I = 630000 ÷ 400 ÷ 1.732 = 909A Maximum output power P = 630 * 0.95 = 599KW (COS ¢ by 0.95) The maximum output power P = 630 * 0.9 = 567KW (COS ¢ by 0.9)
Q:How do I select a transformer connection group?
Both transformers are center-point direct-to-ground transformers. Dyn11 wiring group of the transformer because of its high-voltage winding is triangular wiring, so when the user produces three and three times the harmonic, can be formed in the triangular winding circulation, resulting in magnetic flux to eliminate this harmonic pollution for the grid. The Yyn0 transformer because there is no triangular winding, without this function. If only an independent power supply of small capacity transformer, you can use Yyn0 transformer, such a transformer everywhere, good production. If there is a transformer that may be supplied in parallel with other transformers, or as a backup power source for other power supplies, the same wiring group as other transformers should be selected. If it is recommended for large-capacity industrial transformers Dyn11 transformers are recommended to reduce the contamination of the grid by three or three times the number of harmonics.
Q:What does S11-M-500/10 transformer mean?
S represents three phases 11 design number M indicates sealing 500 indicates that the transformer capacity is 500KVA 10 indicates that the rated voltage of the transformer high voltage side is 10KV
