Quanzhou3000 oil immersed transformerWhat are the basic requirements for homework

Power transformer is one of the key equipment in power station and substation. The function of power transformer is in all aspects. It can not only raise the voltage and send electromagnetic energy to the power consumption area, so as to meet the needs of power consumption. In short, voltage transformation and blood pressure reduction must be carried out by the transformer.

Operation of oil immersed transformer

Quanzhou.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,QuanzhouWhat are the test items of dry-type transformer, epoxy resin adhesive shall be used to pour dry-type transformers.

Dry type transformer factory

.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.

Avoid the load operation of power transformer: if the load operation is long-term,QuanzhouMobile dry type transformer, it will lead to the scalding of solenoid coil, slow aging of insulation, short circuit fault between boxes, two-color short circuit fault or short circuit to ground fault and dissolution of oil.

After 24 hours of continuous trial operation with a certain load, the main body and accessories of the transformer are all normal and the transformer will turn to all normal operation.

Power transformer manufacturer

During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.

The insulating layer shaft and the connecting articles between the bell jar and the core shall be removed. If it is a hanging bell inspection, the oil shall be pumped into the bottom of the bell jar before the bell jar can be removed.

Test conclusion.Before application, the sampling container shall be cleaned with vehicle gasoline, 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 105 ℃ drying oven. After refrigeration, the bottle cap shall be tightly closed and cannot be opened before application.

Before and after sampling, clean the periphery of the sampling port with clean or hairless linen.

Careless maintenance and insulation damage

& 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,QuanzhouPrice list of transformer 3150kva, the resistance value exceeds 2m ohm bus.

Quality Assurance.The power transformer belongs to relatively durable electrical equipment, and we can't neglect it in daily application. The common problems of power transformer conductor, power transformer winding and power transformer tapping power switch are analyzed below:

Oil sample inspection & mdash; & mdash; the performance parameters such as compression resistance and residue shall be carried out every three years. The long-term overload or overload of the transformer can reduce the cycle time.

For 630kVA 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.

Quanzhou.Caused by sand holes and cracks. For crack leakage, drilling stop hole is a good way to remove in-situ stress and prevent widening.

Sound causing short circuit obstruction. If not handled properly, it will cause great damage.
