Wei ChenTransf
PatanOld box tthe high-capacity transformer must be replaced by the small-capacity transformer with high utilization rate,Wei ChenAdvantages of oil immersed transformer, and then the iron loss is considered and the copper loss is ignored. In fact,Wei ChenWorking principle of power transformer, for a certain load, the active power loss of small capacity exceeds that of large capacity The active power loss of the transformer, so it consumes electromagnetic energy.
Oil leakage of porcelain pot and laminated glass oil level gauge
.The method and whole process of taking oil sample of power transformer are as follows:
The raw materials of Fushi blue can be used for bonding, so that the overall oil leakage of the connector can be greatly controlled; If the actual operation is convenient, the metal shell can also be bonded at the same time to achieve the purpose of leakage treatment.
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%.
Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;
How to maintain dry-type transformer?
Different diversion methods, dry-type transformers mostly use silica gel waterproof casing while oil transformers mostly use porcelain waterproof casing;
The cost is reasonable.Oil leakage at looper flange
Falling foreign matters and piercing
(II) the height width ratio of dry-type transformer pier installed on the ground is generally 0.5m, and a warning sign shall be hung at a prominent position.
When sampling in bulk gasoline barrels, samples shall be selected according to 5% of the number of gasoline barrels, but not less than 2 barrels. When sampling in batches of small and medium-sized pails or bottles,Wei ChenWhat are the pressure regulators, samples shall be taken according to 2% of the total number of barrels (bottles).
Job description.Fault judgment of power transformer
With Vietnam and Malaysia, China's first UHV transmission experimental demonstration project, China Transformer Corporation has entered a breakthrough in the development trend. The commodity voltage grade and volume rank first in the world, occupying the main technical position of the industry development trend. In addition, it has promoted the continuous improvement and perfection of the technology of low-voltage transformers.
Sound insulation treatment of main engine room the key to sound insulation treatment of dry-type transformer room is to start from three levels: window, ventilation and air exchange port and road surface, and apply sound insulation window, silencing cylinder, floating concrete floor damping pad and other sound insulation and noise reduction commodities to achieve sound insulation effect.
Wei Chen.When the screw of the through core extruder holding the iron core of the transformer is loose there are screw cap parts left on the iron core, or small metal materials fall into the transformer, the transformer will send out & ldquo; Ding Ding Dang & rdquo; Or & ldquo; Call & hellip; Call & hellip& rdquo; Blowing sound and its & ldquo; Squeak, squeak & rdquo; It's like a magnet sucking a small washer, while the working voltage, current and temperature of the transformer are all normal. Such conditions generally do not endanger all normal operation of the transformer, and can be solved until power failure.
Power transformers are used in all walks of life
