Protective measures for damping of dry-type transformer
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.

Manufacturing process and steps of dry-type transformer
The hanging core of dry-type transformer is a vital part
The domestic transformer market is slow
The whole process of hanging the core of dry-type transformer is more critical， and there are many situations that the hanging core of dry-type transformer must pay special attention to. Therefore， the hanging core of dry-type transformer should be carried out according to the above matters， so as to promote the safety of dry-type transformer!
retailerThere are many connection groups of dry-type transformers， and the selected structures and connections are also different. Then， what are the groups of dry-type transformers? How to carry out the connection? Or basically introduce it with the network of dry-type transformer manufacturers.
Falling foreign matters and piercing
When the power transformer operates at full load， it needs a large reactive load. This reactive load shall be provided by the power supply and distribution system. If the transformer volume is too large， it will not only increase the initial project investment， expand the proportion of full load loss， reduce power factor and increase Internet loss. Such operation is neither economic development nor scientific.
Oil leakage of bolt or pipe external thread
buildWhen sampling from a small and medium-sized power transformer without a discharge pipe (or oil sample suspension plate)， it can be in a power transformer such as a glass test tube when it is not in operation to extract the oil sample at the bottom， or it can be replaced by changing the oil.
The insulation of the through core anchor bolt clamping the iron core is damaged， resulting in a short circuit fault between the silicon steel sheet of the iron core and the through core anchor bolt;
Sound， causing short circuit obstruction. If not handled properly， it will cause great damage.
ManausFrom 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;
The power transformer is designed according to the temperature protection scheme. The embedded parts in the material layer of high (low) pressure electromagnetic coil poured with integral concrete are provided with longitudinal ventilation duct， the output capacity can be increased by %.
(I) the distance between the external contour of kV and below dry-type transformer and the surrounding guardrail or courtyard wall shall take into account the convenience of transportation and repair of dry-type transformer， and the distance shall not be less than m; At the angle with actual operation， a spacing of more than m shall be reserved; If metal fence is selected， the metal fence shall be grounded and a warning sign shall be hung at a prominent position.
