Common problems of tap changer of power transformer

The scientific research of power transformer oil is generally carried out according to the way of sampling. What are the common sampling methods and processes?

Horny posenis.Power transformer is indispensable for power stations and substations, but we must pay attention to many problems in the whole process of applying power transformer.

What is the important role of power transformer

.Due to poor sealing, generally, the sealing of box edge and machine cover is sealed with acid-base resistant rubber rod or rubber plate. If the joint is not solved well it will lead to common faults of oil leakage.

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.

Manufacturing process and steps of dry-type transformer

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.

The rate of transformer is: n = P2 / p1x1o%, that is, when the copper loss of transformer is equivalent to iron loss, the rate is very large. Therefore, the load of transformer is: 0 = P / PK. Fully consider the active power loss caused by reactive power in the system software during transformer operation. The load adjustment is: it can be seen from the calculation of load formula that the large rate of transformer does not occur when the load is full, Generally, it is about 50%, we should select effective transformers according to the load condition and load, so as to make the transformer in the situation of economic development and achieve the goal of power saving.

After the test, connect the data signal contact of the automobile relay with the alarm circuit,Horny posenisTransformer variable frequency power supply, the pull-in contact with the opening circuit, and adjust the overcurrent protection value.

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

High voltage fuse of transformer breaks one phase;

What is the reason for the shutdown of power transformer?

The main reason is that the welding quality of electric welding is poor there are empty welding, open welding, needle holes, sand holes and other shortcomings in welding. The oil transformer is easy to be covered with welding powder and paint when leaving the factory, and the potential safety hazards are exposed after operation. In addition,Horny posenisElectrical transformer, the electromagnetic induction vibration will crack the electric welding and lead to leakage.

technical service.Causes of fire in power transformer

Protection mode for type selection of dry-type test transformer

The power transformer belongs to relatively durable electrical equipment, power transformer winding and power transformer tapping power switch are analyzed below:

Horny posenis.The method and whole process of taking oil sample of power transformer are as follows:

Oil leakage of porcelain pot and laminated glass oil level gauge

Different diversion methods, dry-type transformers mostly use silica gel waterproof casing, while oil transformers mostly use porcelain waterproof casing;
