Zolho630kw box
Kaifei80 KVA oIt is generally made due to unreasonable installation or ineffective sealing. Polymer composite materials can bond metal materials, porcelain, laminated glass and other materials very well, so as to achieve the pressure management of oil leakage.
When the whole process of winding wave of oil immersed transformer is calculated by using the marking method, and each module is replaced by an equivalent circuit,ZolhoImpulse test of dry-type transformer,ZolhoHow much is a 250kVA box transformer, and its power circuit includes an inductance and vertical capacitance, a capacitance to ground or capacitance between windings, They also have mutual inductors between the inductors of each module, and collect the chain Internet as the equivalent power circuit of oil immersed transformer. The precision of the conclusion can completely meet the needs of practical projects.
Zolho.The insulation between silicon steel sheets is damaged, pay attention to the following matters:
The key reason for oil leakage is that there are defects in cast iron parts
Method and process of taking oil sample of power transformer
Transformer inspection ear
Sound,ZolhoPower transformer picture, causing short circuit obstruction. If not handled properly, it will cause great damage.
Recommendation and consultation.Oil immersed transformer operation
What is the important role of power transformer
The method and whole process of taking oil sample of power transformer are as follows:
The tap changer of power transformer shall also have strong insulation. 10kV off load tap changer is generally insulated from the ground by the produced insulating paper pipe factory.
discount.The electromagnetic coil is wound with copper power wire or foil and lifted with glass fiber. The epoxy adhesive does not need filling. The vacuum drying equipment is used for degassing and dehumidification. The overall concrete is poured with high fracture toughness, resistance to short-circuit faults, common faults and impact. The work is diligent.
During the operation of the transformer, the resistance value of the grounding wire shall be measured accurately every two years.
Brief introduction of zero line of power transformer
Zolho.The vibration reduction of the grounding device sheet solves the problem of modifying the fixed hard connection between the copper sheet of the grounding device and the dry-type transformer. The original oscillation of the dry-type transformer will be transmitted to the metal in the concrete by the baffle and cause low-frequency noise. Therefore, it must also be changed to produce flexible connection.
Sound in case of phase failure
(I) the distance between the external contour of 10kV 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 1m; At the angle with actual operation, a spacing of more than 2m 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.
