According to the condition of cracks, galvanized iron wire can be punched into the leakage or riveted with hammer. Then clean the leakage point with toluene and seal it with raw materials. Coated sand casting eyes can be sealed with raw materials immediately.
Ham.The transformer manufacturer will introduce the efficiency of the transformer to you
The insulating layer in the middle of the silicon steel plate is aging, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, resulting in heat temperature rise, and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.
.Some are tied with plastic tape, and some immediately press the two edges together because the socket can not be pressed firmly during installation, 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.

After the oil is drained, all anchor bolts of the automobile oil tank at the upper end of the detachable oil cover shall be tied with the lifting jack, and the lifting point shall be on the common earrings or bolts. If necessary, the human resources traction belt shall be used as a guide.
At rated power, the ratio of output power to input power of transformer is called the efficiency of transformer, i.e. & ETA; Is the efficiency of the transformer; P1 is the input power and P2 is the output power.
The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.
Quality Assurance.In the case of using dry-type transformer, customers must master the method of wiring. If there are problems in wiring, it is easy to cause common faults in application. So what is the wiring mode of dry-type transformer?
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.
If the oil immersed transformer is burned by the cover of the transformer, when the oil immersed transformer fails, open the lower side of the transformer and place an appropriate part. When the oil immersed transformer is on fire, use detection equipment to put out the fire immediately. In order not to expand the hazard, the fire brigade must be notified.
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.
Test results.Dry type transformer factory
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%
Generally speaking, the ignition emergency treatment method of oil immersed transformer is mainly to disconnect the oil immersed transformer, disconnect the switching power supply on each side,HamHow much is a three-phase transformer, quickly invest the reserved oil immersed transformer and start the power supply system from scratch. Stop the operation of refrigeration equipment. Key oil immersed transformer ignition. When L-type oil immersed transformer and high voltage station oil immersed transformer are ignited, the generator set must be disassembled first.
Ham.The capacity and working voltage are different. The dry-type transformer is generally suitable for distribution equipment. The capacity is generally below 2000kVA and the working voltage is below 35KV, which also ensures the rated voltage of 110kV; Oil immersed transformers are generally suitable for distribution equipment.
Performance and main parameters of common metal composites, various welding processes and machinery and equipment, blanking process, production and manufacturing process and quality standards of automobile oil tank, riser, coupling and oil storage tank cabinet, welding leakage test and NDT technology,HamPrice of 400KVA dry type transformer, surface treatment process and quality standards, copper, Production process and quality standard of aluminum shield; Body suit iron insertion process, wire installation process, body dryness solution and dry transformer oil solution process, vacuum pump oil immersion, general installation process, machinery and equipment of each process flow; The natural working environment is basically regulated.
The insulating layer in the middle of the silicon steel plate is aging,HamWhat is the price of 1600KVA transformer, the anchor bolt cover with the iron core is damaged, the iron core causes large vortex, resulting in heat, temperature rise and the aging of the insulating layer is accelerated. The core insulation compressive strength of power transformer must be measured on time and accurately. If it is found that the insulation compressive strength is less than the index value, please remove and replace the anchor bolt cover or carry out insulation for the copper core cable.
