Protective measures for damping of dry-type transformer
Perera.During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.
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?
.Operation of oil immersed transformer
For example, in the 1970s, the radio programs applied by every family in the countryside had a ground wire,PereraPrice list of 315 KVA box type transformer, and they were often wet with tap water. Protective grounding is to bury the copper plate of metal electrical conductor in the soil layer, and then lead a point of it out of the road with transmission line, which completes the grounding protection. The grounding wire specifies the grounding wire resistance ≤ 4Ω. Grounding protection is a safeguard measure adopted to avoid safety accidents when using household appliances, office and other electrical equipment.
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.
From the appearance, the packaging types are different. The transformer core and electromagnetic coil can be seen immediately for dry-type transformer, and only the shell can be seen for oil immersed transformer;
At that time, only a few companies in China could produce 500kV high-voltage transformers, and the market share of high-voltage transformers was basically monopolized by overseas leaders.
The first step of the whole wave process calculation is to calculate the basic parameters of the Internet such as inductance, the good model is the solid model of infinite transformer core column, but there are many calculation methods.
Inspection basis.The power transformer conductor refers to the connecting transmission line between each electromagnetic coil, between the electromagnetic coil and the group outlet pipe, and between the electromagnetic coil and the tap changer.
The long-term overload of power transformer will slowly cause the scalding and insulation aging of solenoid coil, resulting in short circuit between coils, two-color short circuit or short circuit on the ground, resulting in the ignition of power transformer. Therefore, the insulation compressive strength of power transformer shall be tested before installation and operation, and overload is not allowed in the whole process of operation.
Sound, causing short circuit obstruction. If not handled properly, it will cause great damage.
Therefore, in the operation prevention and regulation of relay protection dry-type transformer, it is necessary to find the short-circuit fault point according to the fault situation, lock the fault point, and analyze the short-circuit fault types of relay protection dry-type transformer. At the same time, if all fields are clear,Perera630kVA dry type transformer, disconnect the switching power supply at the fault point the maintenance work of employees will be carried out smoothly, the resistance value exceeds 2m ohm bus.
