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.
North Santa Cruz.The domestic transformer market is slow
High voltage fuse of transformer breaks one phase;
.The flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.
The manufacturing process of dry-type transformer is very process,North Santa CruzEnergy efficiency class I oil immersed transformer, 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?
During no-load test run, the transformer shall be connected with the working voltage from the switching power supply side, and then make the working voltage impulse closing.
Insulation and heat removal are different. Dry type transformers are generally insulated with epoxy resin, insulated by insulating oil in the circulating system inside the transformer, and heat is discharged on the radiator (radiator) of the circulating system inside the transformer.
If the input of dry-type transformer is an alternating switching power supply, its output voltage is directly proportional to the coil turn ratio of the output input solenoid coil. If a rechargeable battery is used because it is DC, add a circuit in the input power supply circuit to change it into a continuously changing voltage. In that way, the alternating DC current can be obtained at the output end.
(III) dry type transformers of 315KVA and below can be installed on poles. The distance between its bottom end and the road surface shall not be less than 5m; The distance between the electrified part and the road surface shall not be less than 5m.
Quality documents.The power transformer conductor refers to the connecting transmission line between each electromagnetic coil,North Santa Cruz800 dry type transformer quotation, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.
Different diversion methods, while oil transformers mostly use porcelain waterproof casing;
& ldquo; YN, D11 & rdquo;, in which 11 indicates that when the working voltage phasor of the primary side line, 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 oil sample can be used only after sufficient standing.
A complete range of products.The flange surface is uneven, the tightening bolts are loose, and the installation and processing process is wrong, so that the bolts are not tightened well, resulting in oil leakage.
First of all, although dry-type transformer has strong moisture resistance, it is generally open structure or very susceptible to moisture, especially the insulation level of dry-type transformer manufactured in China is low (lower flame retardant grade) Therefore,North Santa CruzParameters of 1600KVA dry type transformer, the dry-type transformer can obtain high stability only when the air humidity is below 70%. The dry-type transformer shall also be prevented from stopping operation for a long time to prevent serious damp. When the grounding resistance value is less than 1000 / V (operating voltage), it indicates that the transformer is seriously damp and the trial operation shall be terminated.
When the full load test is carried out and everything is normal, the load can be connected.
North Santa Cruz.Before application the sampling container shall be cleaned with vehicle gasoline, soapy water or other organic solvents (such as trisodium phosphate) except oil stains, and then washed with tap water until it is not alkaline, and the water can be evenly distributed from the bottle, and then cleaned with purified water for many times. The cleaned sampling container shall be dried in a 105 ℃ drying oven. After refrigeration, the bottle cap shall be tightly closed and cannot be opened before application.
