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.
Power transformer factory
a surname.The appropriate power saving calculation formula should be derived from the following process: active power loss of large capacity transformer: load of large capacity transformer; PDK - short-circuit fault loss of large capacity transformer, kW. Active power loss of small capacity transformer: when a pump room is in normal operation, two pumps are started separately, and each pump is driven by 100kW motor, so the usual load is 200 KW, CST = 0. One 750kva transformer was originally configured, and the capacity utilization rate introduced by the transformer manufacturer is only 34%
For 630kVA power engineering transformer, plastic parts are selected in the middle of iron core, clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.
.The heat discharge pipe of heat pipe radiator is generally made of slotted seamless steel pipe after flattening by stamping die. When the heat discharge pipe is bent and welded by electric welding, special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.
Dry type transformer company
After tightening the loose bolts, seal the flange, and solve the bolts that are likely to leak, so as to achieve the goal of complete treatment. Tighten the loose bolts strictly according to the actual operation and processing technology.
The transformer manufacturer will introduce the efficiency of the transformer to you
Noise pollution control and prevention measures of dry-type transformer
system.In order to better reduce the probability of short-circuit fault of relay protection dry-type transformer, prevention and key are & ldquo; Prevention and Manipulation & rdquo; Is dominant.
For 630kVA power engineering transformer, plastic parts are selected in the middle of iron core, clamp and electromagnetic coil to keep the electromagnetic coil in a stable clamping state to reduce noise.
Use fiber materials to seal the bolts to achieve the goal of controlling leakage. The other is to screw out the bolt (nut), wipe the Fushi blue film remover on the surface, and then tighten it after wiping the raw materials on the surface. After drying, the treatment goal can be achieved.
Avoid inadvertent damage of insulation during maintenance: when repairing the hanging core of power transformer special attention shall be paid to the maintenance of solenoid coil or insulating waterproof sleeve. If there is scratch damage, it shall be handled properly.
Welcome calls .Difference between dry-type transformer and oil immersed transformer:
According to statistics, to occupy the main global technical position, the transformer industry depends on two key data, commodity volume and voltage level. As early as & ldquo; Eleventh Five Year Plan; In the early stage, China has been a powerful country in the production, manufacturing and application of dry-type transformers all over the world,a surnamePower equipment transformer, but it is not a big country.
The project cost is different. Compared with the purchase price of capacity transformer, the purchase price of dry-type transformer is much higher than that of oil immersed transformer.
a surname.The manufacturing process of dry-type transformer is very process, and must be technically as a certain pillar. Only in that way, the performance of dry-type transformer will be more stable. What are the common manufacturing processes and steps of dry-type transformer?
Under normal conditions,a surnameAmerican box transformer, the actual operation of the oil immersed transformer shall be undertaken by the on-site operation and maintenance management staff. Within one week of grid connected operation, the operation and maintenance management staff shall improve the safety inspection range of the transformer, so as to ensure the reliable and stable operation of machinery and equipment.
