JorpenOil imme
JorpenWhich isThe clock expression is used to indicate the phase difference correlation of the working voltage of the secondary side line. The phasor of the working voltage of the primary side line is used as the minute hand, the fixed finger is at 12 o'clock, and the phasor of the phase voltage of the secondary side is used as the second hand.
The vibration reduction of collecting and townhouse solves the soft connection of collecting and townhouse. For the copper bar of the low-voltage bus of the equipment, the electromagnetic induced noise oscillation may be transmitted from the townhouse to the building structure. The core of noise reduction solution must be changed to copper wire connection.
Jorpen.The top and middle of the transformer oil tank, the flange plate, barrel skin and the middle of the waterproof sleeve at the upper end of the automobile oil tank. The internal iron core and winding clamp are hot due to partial magnetic leakage, resulting in insulation damage.
After sampling, bind the laminated glass stopper firmly with clean paper or cloth to prevent dirt and water from contaminating the bottle stopper.
.Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, it is necessary to resolutely prevent the invasion of dirt such as rain, snow, wind and sand.
Oil leakage of cast iron parts
The method and whole process of taking oil sample of power transformer are as follows:
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, coupling and oil storage tank cabinet, welding leakage test and NDT technology, surface treatment process and quality standards,JorpenRecovery of transformer cabinet, 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, leakage test and leakage detection process and quality standards. Performance parameters of key work clothes, machinery and equipment of each process flow; The natural working environment is basically regulated.
During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.
Falling foreign matters and piercing
production.The noise of dry-type transformer is mainly the vibration noise in operation. This vibration noise is caused by multiple positions,JorpenTransformer electrical test, including the vibration of magnetic induction electromagnetic coil. All pay great attention to the solution of vibration when carrying out noise control.
Protective measures for damping of dry-type transformer
Connection group structure of dry-type transformer
The iron core of power transformer is made of high-quality crystallized hot-rolled ferrite core, which is stacked at the 45 degree fully inclined multi-step interface. The surface is covered with epoxy resin adhesive cable sheath coating, which is resistant to corrosion and rust, and has sound insulation and noise reduction.
Promise and keep promise.Operation of oil immersed transformer
The selection shall be carried out according to the load characteristics of power. There are many types of power loads. Different dry-type transformers shall be used for different power loads. If the standard impulse level of power load is less than 150kV, class H dry-type transformers shall be used. If the standard impulse level of power load exceeds 150kV epoxy resin adhesive shall be used to pour dry-type transformers.
Outdoor sampling shall be carried out in sunny days or dry weather with low environmental humidity. During sampling, it is necessary to resolutely prevent the invasion of dirt such as rain,JorpenMain transformer of wind farm, wind and sand.
Jorpen.A specific part of dry-type transformer is the hanging core of dry-type transformer. The hanging core of dry-type transformer is a vital component. How to carry out the hanging core?
It will also produce many faults, effectively deal with various faults of oil immersed transformer, make full use of the performance indicators and advantages of oil immersed transformer, and continuously improve the safety factor of oil immersed transformer. Ignition is a common fault of oil immersed transformer. The key fault of oil immersed transformer is short-circuit fault, and short-circuit fault is more general.
