Wacos1600KVA transformer priceThe off-season effect is obvious, and the price continues to decline

in which 11 indicates that when the working voltage phasor of the primary side line D11 & rdquo;, as the minute hand, refers to the position at 12 o'clock the phase voltage phasor of the secondary side is at 11 o'clock. That is, the phase voltage UAB of the secondary side lags 30 degrees behind the working voltage uab330 of the primary side line (or 30 degrees ahead).

Gradually, high-frequency vibration damping mechanical equipment, such as low-frequency vibration damping platform, is installed at the bottom of the dry-type transformer, which can reduce the downward dispersion of the vibration of the dry-type transformer. Then replace the connection between the dry-type transformer and the surrounding engineering buildings, roads,WacosPower transformer model, the dry-type transformer room can also be soundproofed and decorated, and sound-absorbing plates and silencing shutters can be used to improve the soundproofing capacity of the dry-type transformer room.

Power transformer manufacturer

.The oil in the machinery and equipment of the oil storage tank shall generally stand for more than 8h before sampling; it is not necessary to stand when sampling on the running power transformer.

The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core, which is stacked at the 45 degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating, which is resistant to corrosion and rust and has sound insulation and noise reduction.

The hanging core of dry-type transformer is a vital part

Dry type transformer oscillation is solved by applying vibration damping platform to dry-type transformer and carrying out low-frequency vibration reduction management, which can control the oscillation below 0.2%,WacosApplication scope of oil immersed transformer, and then reduce the building structure noise transmitted by dry-type transformer oscillation.

At that time,WacosPrice of 400KVA dry type transformer, only a few companies in China could produce 500kV high-voltage transformers, and the market share of high-voltage transformers was basically monopolized by overseas leaders.

The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct, which can be equipped with air-cooled machinery and equipment (cooling centrifugal fan). After selecting air-cooled machinery and equipment, the output capacity can be increased by 20%.

Welcome to inquire.The clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, the fixed finger is at 12 o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.

How much is the power transformer

The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core, which is stacked at the 45 degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating, which is resistant to corrosion and rust, and has sound insulation and noise reduction.

Equipped with a temperature controller, platinum thermistor (pt10) is placed beside the embedded hole on the top of the low-voltage solenoid coil to test the winding resistance temperature rise of the transformer, stop the cooling centrifugal fan, set up common problem alarm, overtemperature alarm and overtemperature tripping effect, and provide reliable overvoltage protection machinery and equipment for the dry test transformer, so as to test the safety performance of the transformer operation.

Promise and keep promise.Oil leakage of heat pipe radiator

It should be said that after the development trend of these years, the overall level of China's transformer industry at this stage is basically international, and the quality level is no different from that of overseas goods& rdquo; The person in charge of the transformer Federation of China Household Appliance Industry Association said.

In order to better carry out the experiment of power transformer oil, it is necessary to sample the power transformer oil. The sampling work should be carried out on a dry sunny day. The commonly used containers and sampling methods during sampling do immediate harm to whether the specific quality of the oil can be truly reflected. The oil sample for AC voltage withstand test shall not be less than 0.5kg, and the oil sample for simplified experiment shall not be less than 1kg.

Wacos.For the leakage that has already occurred, find the leakage point first, which can not be ignored. For the position with serious leakage, shovel or sharp punch can be selected. The leakage point can be riveted with special tools for metal materials. After manipulating the leakage, the treatment surface shall be cleaned and tidy. Polymer composite materials are mostly selected for dry consolidation. After dry consolidation, the goal of long-term treatment of leakage can be achieved.

For no-load impulse closing of transformer, pay attention to the following matters:
