Analysis of common faults of oil immersed transformer:
Gasanjik.Transformer is
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,GasanjikRecycling box transformer manufacturer, 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.
.Brief introduction of zero line of power transformer
Difference between dry-type transformer and oil immersed transformer:
For the installation of lightning rod, it is very easy to damage the relay protection inside and outside of dry-type transformer by lightning. If it is a serious situation it is very easy to cause fire accidents, power failure, damage to machinery and equipment, etc.
The plastic shells of electrical products and office supplies are equipped with grounding wires. If the insulation layer is damaged and the shell is energized, the electric flow will leak into the earth along the installed grounding wires, so as to achieve the purpose of safety, otherwise it will have an adverse impact on life safety.
It can be seen from the above that from the perspective of power saving, in some cases, transformers & ldquo; A small horse pulls a small car & rdquo; Can't compare with & ldquo; Middle car & rdquo;,GasanjikDry type transformer procurement, Even less than & ldquo; Great Lars, and the results can be properly made in terms of power saving or power consumption. According to the correlation between the load rate and the transformer capacity: 3. The transformer load rate and power saving will be brought into the formula: the load index of the transformer the loss of transformer full load and load must be considered in the calculation, that is, the operating load and rated capacity of the transformer 1. Now it is illustrated by examples that both sides of the acadc al electron touch toe ground type seek the derivative of P, and then reduce the active power loss of the large capacity transformer from the active power loss of the small capacity transformer: that is, the formula is reduced The load index is the load index when the transformer operation loss is small and the rate is large, and the rate is large when the specific copper loss is equivalent to iron loss.
The time difference between different steps of three-phase power switch of switching power supply shall be less than 10ms, the closing shall be maintained by high-voltage arrester, and the neutral line of transformer shall be reliably grounded (it shall be grounded immediately).
Focus on Development.The key reason for oil leakage is that there are defects in cast iron parts
Noise pollution control and prevention measures of dry-type transformer
The switching power supply lacks one phase of power;
When checking the hook core, the insulation of the electromagnetic coil and the porcelain sleeve is usually accidentally damaged. After the shell of the pottery is broken, if you work again, turn on the photo flash when it's light, and it's short when it's heavy. Therefore, please pay attention during maintenance. It is not necessary to destroy the insulation. After maintenance, experts can inspect special tools,GasanjikBrand of oil immersed transformer, parts, insulation, etc. and deliver them after they are determined to be complete and reliable.
Honesty is the foundation.What is the wiring mode of dry-type transformer?
Transformer is
Oil leakage of porcelain pot and laminated glass oil level gauge
Gasanjik.& ldquo; of wiring transformer; Enter & rdquo; And & ldquo; Output & rdquo; Use a megger to test the grounding resistance between the terminal and the ground wire. When accurately measured by 1000V megger, the resistance value exceeds 2m ohm bus.
In relay protection dry-type transformer, if there is any problem at a certain point, it will affect the whole power circuit
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.
