When the power transformer operates at full load, it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large, it will not only increase the initial project investment, but also make the transformer operate at full load or load for a long time, expand the proportion of full load loss, reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.Analysis of common faults of oil immersed transformer:Brigadier general Rivadavia,Accurately measure the resistance of each phase winding and carry out the measurement. If there is a great difference it is a common fault of the winding. Then carry out the appearance inspection of the iron core, and then accurately measure the inter chip insulation resistor by AC voltage and galvanometer method. If the damage is not large, paint the damaged part.The bearing capacity of each load is different. Generally, dry-type transformer should operate under rated capacity, while oil transformer has better load working capacity.Palmerston,The vibration reduction solution of cable bridge is to modify the hard connection between bus bridge and dry-type transformer, and the vibration reduction solution is made at the cable bridge.Therefore, in the installation process of substation equipment, the lightning rod should be set according to the specific situation to prevent damage to the relay protection dry-type transformer caused by lightning. In addition, in the installation and use process of lightning rod, select reasonable types of lightning rod according to the operation situation to determine that they are in the same situation. In addition, during the installation of lightning rod, please connect all routes as far as possible to prevent other faults.When the transformer is out of phase, if the second phase is blocked, there is still no sound when the second phase is sent, and there is sound when the third phase is sent; If the third phase is blocked, the sound will not change, as in the case of the second phase. There are three reasons for phase deficiency:

Deterioration damage of transformer core insulationIn order to better avoid overvoltage damage, a group of overvoltage maintenance high-voltage Arresters (such as ycs active zinc oxide high-voltage arresters) shall be refitted at the working voltage bus duct side of dry-type transformer.When leaving the factory, the production and processing are not smooth and the sealing is poor. The common fault of oil leakage will be caused after the oil transformer is sealed for a period of time.Fair price,Loose core screwDue to careless transportation of the transformer and the thin high-voltage conductor,Brigadier general RivadaviaParameters of oil immersed transformer, the transformer was disconnected by vibration (but there was no grounding device).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, 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,Brigadier general Rivadavia200 KVA 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?Manufacturing cost,Before application,Brigadier general RivadaviaUnit price of scb11 dry type transformer, 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 ℃ drying oven. After refrigeration, the bottle cap shall be tightly closed and cannot be opened before application.Several detection methods for installing transformerNoise dispersion of dry-type transformerBrigadier general Rivadavia,Power transformerFor kVA 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 installation position of secondary commercial insurance of transformer on column and ground shall meet the following requirements: if there is an disconnector on the secondary side, it shall be installed between the disconnector and low-voltage composite insulator, or the circuit breaker shall be selected as the disconnector; If there is no disconnector on the secondary side, it shall be installed on both sides of the low-voltage composite insulator
